GNU C Library NEWS -- history of user-visible changes.
Update copyright dates with scripts/update-copyrights I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

Extend struct r_debug to support multiple namespaces [BZ #15971] Glibc does not provide an interface for debugger to access libraries loaded in multiple namespaces via dlmopen. The current rtld-debugger interface is described in the file: elf/rtld-debugger-interface.txt under the "Standard debugger interface" heading. This interface only provides access to the first link-map (LM_ID_BASE). 1. Bump r_version to 2 when multiple namespaces are used. This triggers the GDB bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28236 2. Add struct r_debug_extended to extend struct r_debug into a linked-list, where each element correlates to an unique namespace. 3. Initialize the r_debug_extended structure. Bump r_version to 2 for the new namespace and add the new namespace to the namespace linked list. 4. Add _dl_debug_update to return the address of struct r_debug' of a namespace. 5. Add a hidden symbol, _r_debug_extended, for struct r_debug_extended. 6. Provide the symbol, _r_debug, with size of struct r_debug, as an alias of _r_debug_extended, for programs which reference _r_debug. This fixes BZ #15971.

* Bump r_version in the debugger interface to 2 and add a new field,
r_next, support multiple namespaces.
Add generic C.UTF-8 locale (Bug 17318) We add a new C.UTF-8 locale. This locale is not builtin to glibc, but is provided as a distinct locale. The locale provides full support for UTF-8 and this includes full code point sorting via STRCMP-based collation (strcmp or wcscmp). The collation uses a new keyword 'codepoint_collation' which drops all collation rules and generates an empty zero rules collation to enable STRCMP usage in collation. This ensures that we get full code point sorting for C.UTF-8 with a minimal 1406 bytes of overhead (LC_COLLATE structure information and ASCII collating tables). The new locale is added to SUPPORTED. Minimal test data for specific code points (minus those not supported by collate-test) is provided in C.UTF-8.in, and this verifies code point sorting is working reasonably across the range. The locale was tested manually with the full set of code points without failure. The locale is harmonized with locales already shipping in various downstream distributions. A new tst-iconv9 test is added which verifies the C.UTF-8 locale is generally usable. Testing for fnmatch, regexec, and recomp is provided by extending bug-regex1, bugregex19, bug-regex4, bug-regex6, transbug, tst-fnmatch, tst-regcomp-truncated, and tst-regex to use C.UTF-8. Tested on x86_64 or i686 without regression. Reviewed-by: Florian Weimer <fweimer@redhat.com>

* Support for the C.UTF-8 locale has been added to glibc. The locale
supports full code-point sorting for all valid Unicode code points. A
limitation in the framework for fnmatch, regexec, and regcomp requires
a compromise to save space and only ASCII-based range expressions are
supported for now (see bug 28255). The full size of the locale is
only ~400KiB, with 346KiB coming from LC_CTYPE information for
Unicode. This locale harmonizes downstream C.UTF-8 already shipping
in various downstream distributions. The locale is not built into
glibc, and must be installed.

Add narrowing square root functions This patch adds the narrowing square root functions from TS 18661-1 / TS 18661-3 / C2X to glibc's libm: fsqrt, fsqrtl, dsqrtl, f32sqrtf64, f32sqrtf32x, f32xsqrtf64 for all configurations; f32sqrtf64x, f32sqrtf128, f64sqrtf64x, f64sqrtf128, f32xsqrtf64x, f32xsqrtf128, f64xsqrtf128 for configurations with _Float64x and _Float128; __f32sqrtieee128 and __f64sqrtieee128 aliases in the powerpc64le case (for calls to fsqrtl and dsqrtl when long double is IEEE binary128). Corresponding tgmath.h macro support is also added. The changes are mostly similar to those for the other narrowing functions previously added, so the description of those generally applies to this patch as well. However, the not-actually-narrowing cases (where the two types involved in the function have the same floating-point format) are aliased to sqrt, sqrtl or sqrtf128 rather than needing a separately built not-actually-narrowing function such as was needed for add / sub / mul / div. Thus, there is no __nldbl_dsqrtl name for ldbl-opt because no such name was needed (whereas the other functions needed such a name since the only other name for that entry point was e.g. f32xaddf64, not reserved by TS 18661-1); the headers are made to arrange for sqrt to be called in that case instead. The DIAG_* calls in sysdeps/ieee754/soft-fp/s_dsqrtl.c are because they were observed to be needed in GCC 7 testing of riscv32-linux-gnu-rv32imac-ilp32. The other sysdeps/ieee754/soft-fp/ files added didn't need such DIAG_* in any configuration I tested with build-many-glibcs.py, but if they do turn out to be needed in more files with some other configuration / GCC version, they can always be added there. I reused the same test inputs in auto-libm-test-in as for non-narrowing sqrt rather than adding extra or separate inputs for narrowing sqrt. The tests in libm-test-narrow-sqrt.inc also follow those for non-narrowing sqrt. Tested as followed: natively with the full glibc testsuite for x86_64 (GCC 11, 7, 6) and x86 (GCC 11); with build-many-glibcs.py with GCC 11, 7 and 6; cross testing of math/ tests for powerpc64le, powerpc32 hard float, mips64 (all three ABIs, both hard and soft float). The different GCC versions are to cover the different cases in tgmath.h and tgmath.h tests properly (GCC 6 has _Float* only as typedefs in glibc headers, GCC 7 has proper _Float* support, GCC 8 adds __builtin_tgmath).
2021-09-10 20:56:22 +00:00
* <math.h> functions that round their results to a narrower type, and
corresponding <tgmath.h> macros, are added from TS 18661-1:2014, TS
18661-3:2015 and draft ISO C2X:
- fsqrt, fsqrtl, dsqrtl and corresponding fMsqrtfN, fMsqrtfNx,
fMxsqrtfN and fMxsqrtfNx functions.
Add narrowing fma functions This patch adds the narrowing fused multiply-add functions from TS 18661-1 / TS 18661-3 / C2X to glibc's libm: ffma, ffmal, dfmal, f32fmaf64, f32fmaf32x, f32xfmaf64 for all configurations; f32fmaf64x, f32fmaf128, f64fmaf64x, f64fmaf128, f32xfmaf64x, f32xfmaf128, f64xfmaf128 for configurations with _Float64x and _Float128; __f32fmaieee128 and __f64fmaieee128 aliases in the powerpc64le case (for calls to ffmal and dfmal when long double is IEEE binary128). Corresponding tgmath.h macro support is also added. The changes are mostly similar to those for the other narrowing functions previously added, especially that for sqrt, so the description of those generally applies to this patch as well. As with sqrt, I reused the same test inputs in auto-libm-test-in as for non-narrowing fma rather than adding extra or separate inputs for narrowing fma. The tests in libm-test-narrow-fma.inc also follow those for non-narrowing fma. The non-narrowing fma has a known bug (bug 6801) that it does not set errno on errors (overflow, underflow, Inf * 0, Inf - Inf). Rather than fixing this or having narrowing fma check for errors when non-narrowing does not (complicating the cases when narrowing fma can otherwise be an alias for a non-narrowing function), this patch does not attempt to check for errors from narrowing fma and set errno; the CHECK_NARROW_FMA macro is still present, but as a placeholder that does nothing, and this missing errno setting is considered to be covered by the existing bug rather than needing a separate open bug. missing-errno annotations are duly added to many of the auto-libm-test-in test inputs for fma. This completes adding all the new functions from TS 18661-1 to glibc, so will be followed by corresponding stdc-predef.h changes to define __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__, as the support for TS 18661-1 will be at a similar level to that for C standard floating-point facilities up to C11 (pragmas not implemented, but library functions done). (There are still further changes to be done to implement changes to the types of fromfp functions from N2548.) Tested as followed: natively with the full glibc testsuite for x86_64 (GCC 11, 7, 6) and x86 (GCC 11); with build-many-glibcs.py with GCC 11, 7 and 6; cross testing of math/ tests for powerpc64le, powerpc32 hard float, mips64 (all three ABIs, both hard and soft float). The different GCC versions are to cover the different cases in tgmath.h and tgmath.h tests properly (GCC 6 has _Float* only as typedefs in glibc headers, GCC 7 has proper _Float* support, GCC 8 adds __builtin_tgmath).

- ffma, ffmal, dfmal and corresponding fMfmafN, fMfmafNx, fMxfmafN and
fMxfmafNx functions.
Add fmaximum, fminimum functions C2X adds new <math.h> functions for floating-point maximum and minimum, corresponding to the new operations that were added in IEEE 754-2019 because of concerns about the old operations not being associative in the presence of signaling NaNs. fmaximum and fminimum handle NaNs like most <math.h> functions (any NaN argument means the result is a quiet NaN). fmaximum_num and fminimum_num handle both quiet and signaling NaNs the way fmax and fmin handle quiet NaNs (if one argument is a number and the other is a NaN, return the number), but still raise "invalid" for a signaling NaN argument, making them exceptions to the normal rule that a function with a floating-point result raising "invalid" also returns a quiet NaN. fmaximum_mag, fminimum_mag, fmaximum_mag_num and fminimum_mag_num are corresponding functions returning the argument with greatest or least absolute value. All these functions also treat +0 as greater than -0. There are also corresponding <tgmath.h> type-generic macros. Add these functions to glibc. The implementations use type-generic templates based on those for fmax, fmin, fmaxmag and fminmag, and test inputs are based on those for those functions with appropriate adjustments to the expected results. The RISC-V maintainers might wish to add optimized versions of fmaximum_num and fminimum_num (for float and double), since RISC-V (F extension version 2.2 and later) provides instructions corresponding to those functions - though it might be at least as useful to add architecture-independent built-in functions to GCC and teach the RISC-V back end to expand those functions inline, which is what you generally want for functions that can be implemented with a single instruction. Tested for x86_64 and x86, and with build-many-glibcs.py.
2021-09-28 23:31:35 +00:00
* <math.h> functions for floating-point maximum and minimum,
corresponding to new operations in IEEE 754-2019, and corresponding
<tgmath.h> macros, are added from draft ISO C2X: fmaximum,
fmaximum_num, fmaximum_mag, fmaximum_mag_num, fminimum, fminimum_num,
fminimum_mag, fminimum_mag_num and corresponding functions for float,
long double, _FloatN and _FloatNx.
Define __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__ TS 18661-1 and C2X specify predefined macros __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__, making __STDC_IEC_559__ and __STDC_IEC_559_COMPLEX__ obsolescent (but still included in the standard). Now that we have all the functions from TS 18661-1, define these macros in stdc-predef.h, under the same conditions in which the older macros are defined, since support for the floating-point features in TS 18661-1 is now at the same level as that for those in C11 and before (all library functions and other library APIs present, but no standard pragma support). The macros are defined for now with their TS 18661-1 values. C2X will give them new values (listed as yyyymmL in the working drafts until the final standard), at which point there will be the question of what value to use in stdc-predef.h (where it could depend on __STDC_VERSION__, but not on feature test macros defined by the user). My inclination then would be to use the C2X value unconditionally rather than using an older value to indicate TS support, and only have any C standard version conditionals for the value when subsequent C standard versions define further values. (Note that I'm also inclined, when we implement the C2X change to the return types of fromfp functions, to make that change unconditional much like the change made to the types of totalorder functions, with the old version only supported with compat symbols for already-linked programs and not as an API for newly built objects. So using the C2X value would also accurately reflect not supporting the versions of APIs in the TS where those ended up being incompatible with the first version actually added to the standard.) Tested for x86_64.
2021-09-24 20:11:56 +00:00
* The __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__ macros are
predefined as specified in TS 18661-1:2014.
Add exp10 macro to <tgmath.h> (bug 26108) glibc has had exp10 functions since long before they were standardized; now they are standardized in TS 18661-4 and C2X, they are also specified there to have a corresponding type-generic macro. Add one to <tgmath.h>, so fixing bug 26108. glibc doesn't have other functions from TS 18661-4 yet, but when added, it will be natural to add the type-generic macro for each function family at the same time as the functions. Tested for x86_64.
2021-09-30 20:40:34 +00:00
* The exp10 functions in <math.h> now have a corresponding type-generic
macro in <tgmath.h>.
Add C2X _PRINTF_NAN_LEN_MAX C2X adds a macro _PRINTF_NAN_LEN_MAX to <stdio.h>, giving the maximum length of printf output for a NaN. glibc never includes an n-char-sequence in its printf output for NaNs, so the correct value for glibc is 4 ("-nan" or "-NAN"); define the macro accordingly. This patch makes the macro definition conditional on __GLIBC_USE (ISOC2X), as is generally done with features from new standard versions. The name is in the implementation namespace for older standards, so it would also be possible to define it unconditionally. Tested for x86_64.
2021-09-30 20:53:34 +00:00
* The ISO C2X macro _PRINTF_NAN_LEN_MAX has been added to <stdio.h>.
elf: Fix slow DSO sorting behavior in dynamic loader (BZ #17645) This second patch contains the actual implementation of a new sorting algorithm for shared objects in the dynamic loader, which solves the slow behavior that the current "old" algorithm falls into when the DSO set contains circular dependencies. The new algorithm implemented here is simply depth-first search (DFS) to obtain the Reverse-Post Order (RPO) sequence, a topological sort. A new l_visited:1 bitfield is added to struct link_map to more elegantly facilitate such a search. The DFS algorithm is applied to the input maps[nmap-1] backwards towards maps[0]. This has the effect of a more "shallow" recursion depth in general since the input is in BFS. Also, when combined with the natural order of processing l_initfini[] at each node, this creates a resulting output sorting closer to the intuitive "left-to-right" order in most cases. Another notable implementation adjustment related to this _dl_sort_maps change is the removing of two char arrays 'used' and 'done' in _dl_close_worker to represent two per-map attributes. This has been changed to simply use two new bit-fields l_map_used:1, l_map_done:1 added to struct link_map. This also allows discarding the clunky 'used' array sorting that _dl_sort_maps had to sometimes do along the way. Tunable support for switching between different sorting algorithms at runtime is also added. A new tunable 'glibc.rtld.dynamic_sort' with current valid values 1 (old algorithm) and 2 (new DFS algorithm) has been added. At time of commit of this patch, the default setting is 1 (old algorithm). Signed-off-by: Chung-Lin Tang <cltang@codesourcery.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* In order to support smoother in-place-upgrades and to simplify
the implementation of the runtime all functionality formerly
implemented in the libraries libpthread, libdl, libutil, libanl has
been integrated into libc. New applications do not need to link with
-lpthread, -ldl, -lutil, -lanl anymore. For backwards compatibility,
empty static archives libpthread.a, libdl.a, libutil.a, libanl.a are
provided, so that the linker options keep working. Applications which
have been linked against glibc 2.33 or earlier continue to load the
corresponding shared objects (which are now empty). The integration
of those libraries into libc means that additional symbols become
available by default. This can cause applications that contain weak
references to take unexpected code paths that would only have been
used in previous glibc versions when e.g. preloading libpthread.so.0,
potentially exposing application bugs.

Add C2X timespec_getres ISO C2X adds a timespec_getres function alongside the C11 timespec_get, with functionality similar to that of POSIX clock_getres (including allowing a NULL pointer to be passed to the function). Implement this function for glibc, similarly to the implementation of timespec_get. This includes a basic test like that of timespec_get, but no documentation in the manual, given that TIME_UTC and timespec_get aren't documented in the manual at all. The handling of 64-bit time follows that in timespec_get; people maintaining patch series for 64-bit time will need to update them accordingly (to export __timespec_getres64, redirect calls in time.h and run the test for _TIME_BITS=64). Tested for x86_64 and x86, and (previous version; only testcase differs) with build-many-glibcs.py.

* The ISO C2X function timespec_getres has been added.
Update floating-point feature test macro handling for C2X ISO C2X has made some changes to the handling of feature test macros related to features from the floating-point TSes, and to exactly what such features are present in what headers, that require corresponding changes in glibc. * For the few features that were controlled by __STDC_WANT_IEC_60559_BFP_EXT__ (and the corresponding DFP macro) in C2X, there is now instead a new feature test macro __STDC_WANT_IEC_60559_EXT__ covering both binary and decimal FP. This controls CR_DECIMAL_DIG in <float.h> (provided by GCC; I implemented support for the new feature test macro for GCC 11) and the totalorder and payload functions in <math.h>. C2X no longer says anything about __STDC_WANT_IEC_60559_BFP_EXT__ (so it's appropriate for that macro to continue to enable exactly the features from TS 18661-1). * The SNAN macros for each floating-point type have moved to <float.h> (and been renamed in the process). Thus, the copies in <math.h> should only be defined for __STDC_WANT_IEC_60559_BFP_EXT__, not for C2X. * The fmaxmag and fminmag functions have been removed (replaced by new functions for the new min/max operations in IEEE 754-2019). Thus those should also only be declared for __STDC_WANT_IEC_60559_BFP_EXT__. * The _FloatN / _FloatNx handling for the last two points in glibc is trickier, since __STDC_WANT_IEC_60559_TYPES_EXT__ is still in C2X (the integration of TS 18661-3 as an Annex, that is, which hasn't yet been merged into the C standard git repository but has been accepted by WG14), so C2X with that macro should not declare some things that are declared for older standards with that macro. The approach taken here is to provide the declarations (when __STDC_WANT_IEC_60559_TYPES_EXT__ is enabled) only when (defined __USE_GNU || !__GLIBC_USE (ISOC2X)), so if C2X features are enabled then those declarations (that are only in TS 18661-3 and not in C2X) will only be provided if _GNU_SOURCE is defined as well. Thus _GNU_SOURCE remains a superset of the TS features as well as of C2X. Some other somewhat related changes in C2X are not addressed here. There's an open proposal not to include the fmin and fmax functions for the _FloatN / _FloatNx types, given the new min/max operations, which could be handled like the previous point if adopted. And the fromfp functions have been changed to return a result in floating type rather than intmax_t / uintmax_t; my inclination there is to treat that like that change of totalorder type (new symbol versions etc. for the ABI change; old versions become compat symbols and are no longer supported as an API). Tested for x86_64 and x86.
2021-06-01 14:22:06 +00:00
* The feature test macro __STDC_WANT_IEC_60559_EXT__, from draft ISO
C2X, is supported to enable declarations of functions defined in Annex F
of C2X. Those declarations are also enabled when
__STDC_WANT_IEC_60559_BFP_EXT__, as specified in TS 18661-1, is
defined, and when _GNU_SOURCE is defined.
Add build option to disable usage of scv on powerpc Commit 68ab82f56690ada86ac1e0c46bad06ba189a10ef added support for the scv syscall ABI on powerpc. Since then systems that have kernel and processor support started using scv. However adding the proper support for a new syscall ABI requires changes to several other projects (e.g. qemu, valgrind, strace, kernel), which are gradually receiving support. Meanwhile, having a way to disable scv on glibc at build time can be useful for distros that may encounter conflicts with projects that still do not support the scv ABI, buying time until proper support is added. This commit adds a --disable-scv option that disables scv support and uses sc for all syscalls, like before commit 68ab82f56690ada86ac1e0c46bad06ba189a10ef.

only supported when LFS (_FILE_OFFSET_BITS=64) is also enabled. It is
only enabled for Linux and the full support requires a minimum kernel
version of 5.1.
y2038: Add support for 64-bit time on legacy ABIs A new build flag, _TIME_BITS, enables the usage of the newer 64-bit time symbols for legacy ABI (where 32-bit time_t is default). The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time.

posix: Add _Fork [BZ #4737] Austin Group issue 62 [1] dropped the async-signal-safe requirement for fork and provided a async-signal-safe _Fork replacement that does not run the atfork handlers. It will be included in the next POSIX standard. It allow to close a long standing issue to make fork AS-safe (BZ#4737). As indicated on the bug, besides the internal lock for the atfork handlers itself; there is no guarantee that the handlers itself will not introduce more AS-safe issues. The idea is synchronize fork with the required internal locks to allow children in multithread processes to use mostly of standard function (even though POSIX states only AS-safe function should be used). On signal handles, _Fork should be used intead and only AS-safe functions should be used. For testing, the new tst-_Fork only check basic usage. I also added a new tst-mallocfork3 which uses the same strategy to check for deadlock of tst-mallocfork2 but using threads instead of subprocesses (and it does deadlock if it replaces _Fork with fork).

to call async-signal-safe functions (such as raise or execve). This function
is currently a GNU extension.

* The posix_spawn_file_actions_addclosefrom_np function has been added,
enabling posix_spawn and posix_spawnp to close all file descriptors greater
than or equal to a given integer. This function is a GNU extension,
although Solaris also provides a similar function.
posix: Add posix_spawn_file_actions_addclosefrom_np This patch adds a way to close a range of file descriptors on posix_spawn as a new file action. The API is similar to the one provided by Solaris 11 [1], where the file action causes the all open file descriptors greater than or equal to input on to be closed when the new process is spawned. The function posix_spawn_file_actions_addclosefrom_np is safe to be implemented by iterating over /proc/self/fd, since the Linux spawni.c helper process does not use CLONE_FILES, so its has own file descriptor table and any failure (in /proc operation) aborts the process creation and returns an error to the caller. I am aware that this file action might be redundant to the current approach of POSIX in promoting O_CLOEXEC in more interfaces. However O_CLOEXEC is still not the default and for some specific usages, the caller needs to close all possible file descriptors to avoid them leaking. Some examples are CPython (discussed in BZ#10353) and OpenJDK jspawnhelper [2] (where OpenJDK spawns a helper process to exactly closes all file descriptors). Most likely any environment which calls functions that might open file descriptor under the hood and aim to use posix_spawn might face the same requirement.

mtrace: Deprecate mallwatch and tr_break The variable and function pair appear to provide a way for users to set conditional breakpoints in mtrace when a specific address is returned by the allocator. This can be achieved by using conditional breakpoints in gdb so it is redundant. There is no documentation of this interface in the manual either, so it appears to have been a hack that got added to debug malloc. Deprecate these symbols and do not call tr_break anymore.

* The symbols mallwatch and tr_break are now deprecated and no longer used in
mtrace. Similar functionality can be achieved by using conditional
breakpoints within mtrace functions from within gdb.
Remove __morecore and __default_morecore Make the __morecore and __default_morecore symbols compat-only and remove their declarations from the API.

* The __morecore and __after_morecore_hook malloc hooks and the default
implementation __default_morecore have been removed from the API. Existing
applications will continue to link against these symbols but the interfaces
no longer have any effect on malloc.
Move malloc hooks into a compat DSO Remove all malloc hook uses from core malloc functions and move it into a new library libc_malloc_debug.so. With this, the hooks now no longer have any effect on the core library. libc_malloc_debug.so is a malloc interposer that needs to be preloaded to get hooks functionality back so that the debugging features that depend on the hooks, i.e. malloc-check, mcheck and mtrace work again. Without the preloaded DSO these debugging features will be nops. These features will be ported away from hooks in subsequent patches. Similarly, legacy applications that need hooks functionality need to preload libc_malloc_debug.so. The symbols exported by libc_malloc_debug.so are maintained at exactly the same version as libc.so. Finally, static binaries will no longer be able to use malloc debugging features since they cannot preload the debugging DSO.

* Debugging features in malloc such as the MALLOC_CHECK_ environment variable
(or the glibc.malloc.check tunable), mtrace() and mcheck() have now been
disabled by default in the main C library. Users looking to use these
features now need to preload a new debugging DSO libc_malloc_debug.so to get
this functionality back.
Move malloc_{g,s}et_state to libc_malloc_debug These deprecated functions are only safe to call from __malloc_initialize_hook and as a result, are not useful in the general case. Move the implementations to libc_malloc_debug so that existing binaries that need it will now have to preload the debug DSO to work correctly. This also allows simplification of the core malloc implementation by dropping all the undumping support code that was added to make malloc_set_state work. One known breakage is that of ancient emacs binaries that depend on this. They will now crash when running with this libc. With LD_BIND_NOW=1, it will terminate immediately because of not being able to find malloc_set_state but with lazy binding it will crash in unpredictable ways. It will need a preloaded libc_malloc_debug.so so that its initialization hook is executed to allow its malloc implementation to work properly.

Remove malloc hooks [BZ #23328] Make malloc hooks symbols compat-only so that new applications cannot link against them and remove the declarations from the API.

* The deprecated memory allocation hooks __malloc_hook, __realloc_hook,
__memalign_hook and __free_hook are now removed from the API. Compatibility
symbols are present to support legacy programs but new applications can no
longer link to these symbols. These hooks no longer have any effect on glibc
functionality. The malloc debugging DSO libc_malloc_debug.so currently
supports hooks and can be preloaded to get this functionality back for older
programs. However this is a transitional measure and may be removed in a
future release of the GNU C Library. Users may port away from these hooks by
writing and preloading their own malloc interposition library.

Changes to build and runtime requirements:
linux: Require /dev/shm as the shared memory file system Previously, glibc would pick an arbitrary tmpfs file system from /proc/mounts if /dev/shm was not available. This could lead to an unsuitable file system being picked for the backing storage for shm_open, sem_open, and related functions. This patch introduces a new function, __shm_get_name, which builds the file name under the appropriate (now hard-coded) directory. It is called from the various shm_* and sem_* function. Unlike the SHM_GET_NAME macro it replaces, the callers handle the return values and errno updates. shm-directory.c is moved directly into the posix subdirectory because it can be implemented directly using POSIX functionality. It resides in libc because it is needed by both librt and nptl/htl. In the sem_open implementation, tmpfname is initialized directly from a string constant. This happens to remove one alloca call. Checked on x86_64-linux-gnu.
2021-02-03 11:55:13 +00:00
* On Linux, the shm_open, sem_open, and related functions now expect the
file shared memory file system to be mounted at /dev/shm. These functions
no longer search among the system's mount points for a suitable
replacement if /dev/shm is not available.

The features array can be expanded with backward binary compatibility for both .o and .so files. When COMMON_CPUID_INDEX_MAX is increased to support new processor features, __x86_get_cpu_features in the older glibc binaries returns NULL and HAS_CPU_FEATURE/CPU_FEATURE_USABLE return false on the new processor feature. No new symbol version is neeeded. Both CPU_FEATURE_USABLE and HAS_CPU_FEATURE are provided. HAS_CPU_FEATURE can be used to identify processor features. Note: Although GCC has __builtin_cpu_supports, it only supports a subset of <sys/platform/x86.h> and it is equivalent to CPU_FEATURE_USABLE. It doesn't support HAS_CPU_FEATURE.

Introduce _FORTIFY_SOURCE=3 Introduce a new _FORTIFY_SOURCE level of 3 to enable additional fortifications that may have a noticeable performance impact, allowing more fortification coverage at the cost of some performance. With llvm 9.0 or later, this will replace the use of __builtin_object_size with __builtin_dynamic_object_size. __builtin_dynamic_object_size ----------------------------- __builtin_dynamic_object_size is an LLVM builtin that is similar to __builtin_object_size. In addition to what __builtin_object_size does, i.e. replace the builtin call with a constant object size, __builtin_dynamic_object_size will replace the call site with an expression that evaluates to the object size, thus expanding its applicability. In practice, __builtin_dynamic_object_size evaluates these expressions through malloc/calloc calls that it can associate with the object being evaluated. A simple motivating example is below; -D_FORTIFY_SOURCE=2 would miss this and emit memcpy, but -D_FORTIFY_SOURCE=3 with the help of __builtin_dynamic_object_size is able to emit __memcpy_chk with the allocation size expression passed into the function: void *copy_obj (const void *src, size_t alloc, size_t copysize) { void *obj = malloc (alloc); memcpy (obj, src, copysize); return obj; } Limitations ----------- If the object was allocated elsewhere that the compiler cannot see, or if it was allocated in the function with a function that the compiler does not recognize as an allocator then __builtin_dynamic_object_size also returns -1. Further, the expression used to compute object size may be non-trivial and may potentially incur a noticeable performance impact. These fortifications are hence enabled at a new _FORTIFY_SOURCE level to allow developers to make a choice on the tradeoff according to their environment.
2020-12-30 06:24:00 +00:00
* A new fortification level _FORTIFY_SOURCE=3 is available. At this level,
glibc may use additional checks that may have an additional performance
overhead. At present these checks are available only on LLVM 9 and later.
The latest GCC available at this time (10.2) does not support this level of
fortification.

elf: Do not search HWCAP subdirectories in statically linked binaries This functionality does not seem to be useful since static dlopen is mostly used for iconv/character set conversion and NSS support. gconv modules are loaded with full paths anyway, so that the HWCAP subdirectory logic does not apply.

Move vtimes to a compatibility symbol I couldn't pinpoint which standard has added it, but no other POSIX system supports it and/or no longer provide it. The 'struct vtimes' also has a lot of drawbacks due its limited internal type size. I couldn't also see find any project that actually uses this symbol, either in some dignostic way (such as sanitizer). So I think it should be safer to just move to compat symbol, instead of deprecated. The idea it to avoid new ports to export such broken interface (riscv32 for instance). Checked on x86_64-linux-gnu and i686-linux-gnu.
2020-10-16 17:51:40 +00:00
* The deprecated <sys/vtimes.h> header and the function vtimes have been
removed. To support old binaries, the vtimes function continues to exist
as a compatibility symbol. Applications should use the getrlimit or
prlimit.

S390: Derive float_t from FLT_EVAL_METHOD float_t supposedly represents the type that is used to evaluate float expressions internally. While the isa supports single-precision float operations, the port of glibc to s390 incorrectly deferred to the generic definitions which, back then, tied float_t to double. gcc by default evaluates float in single precision, so that scenario violates the C standard (sections 5.2.4.2.2 and 7.12 in C11/C17). With -fexcess-precision=standard, gcc evaluates float in double precision, which aligns with the standard yet at the cost of added conversion instructions. With this patch, we drop the s390-specific definition of float_t and defer to the default behavior, which aligns float_t with the compiler-defined FLT_EVAL_METHOD in a standard-compliant way. Checked on s390x-linux-gnu with 31-bit and 64-bit builds.
2020-11-30 14:53:59 +00:00
* On s390(x), the type float_t is now derived from the macro
__FLT_EVAL_METHOD__ that is defined by the compiler, instead of being
hardcoded to double. This does not affect the ABI of any libraries
that are part of the GNU C Library, but may affect the ABI of other
libraries that use this type in their interfaces. The new definition
improves consistency with compiler behavior in many scenarios.
NEWS: Add entry for glibc-hwcaps and deprecate legacy hwcaps
2021-01-29 16:26:18 +00:00
* A future version of glibc will stop loading shared objects from the
"tls" subdirectories on the library search path, the subdirectory that
corresponds to the AT_PLATFORM system name, and also stop employing
the legacy AT_HWCAP search mechanism. Applications should switch to
the new glibc-hwcaps mechanism instead; if they do not do that, only
the baseline version (directly from the search path directory) will be
loaded.

Changes to build and runtime requirements:
Linux: Require properly configured /dev/pts for PTYs Current systems do not have BSD terminals, so the fallback code in posix_openpt/getpt does not do anything. Also remove the file system check for /dev/pts. Current systems always have a devpts file system mounted there if /dev/ptmx exists. grantpt is now essentially a no-op. It only verifies that the argument is a ptmx-descriptor. Therefore, this change indirectly addresses bug 24941. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2020-10-07 12:55:04 +00:00
* On Linux, the system administrator needs to configure /dev/pts with
the intended access modes for pseudo-terminals. glibc no longer
attemps to adjust permissions of terminal devices. The previous glibc
defaults ("tty" group, user read/write and group write) already
corresponded to what most systems used, so that grantpt did not
perform any adjustments.
* On Linux, the posix_openpt and getpt functions no longer attempt to
use legacy (BSD) pseudo-terminals and assume that if /dev/ptmx exists
(and pseudo-terminals are supported), a devpts file system is mounted
on /dev/pts. Current systems already meet these requirements.

NEWS: Mention CVE-2021-3326 (iconv assertion with ISO-20220-JP-3)
2021-01-29 16:29:57 +00:00
This assertion was triggered by certain valid inputs in which the
converted output contains a combined sequence of two wide characters
crossing a buffer boundary. Reported by Tavis Ormandy.
iconv: Accept redundant shift sequences in IBM1364 [BZ #26224] The IBM1364, IBM1371, IBM1388, IBM1390 and IBM1399 character sets share converter logic (iconvdata/ibm1364.c) which would reject redundant shift sequences when processing input in these character sets. This led to a hang in the iconv program (CVE-2020-27618). This commit adjusts the converter to ignore redundant shift sequences and adds test cases for iconv_prog hangs that would be triggered upon their rejection. This brings the implementation in line with other converters that also ignore redundant shift sequences (e.g. IBM930 etc., fixed in commit 692de4b3960d).

pthread_attr_getsigmask_np have been added. They allow applications
to specify the signal mask of a thread created with pthread_create.
Add the __libc_single_threaded variable The variable is placed in libc.so, and it can be true only in an outer libc, not libcs loaded via dlmopen or static dlopen. Since thread creation from inner namespaces does not work, pthread_create can update __libc_single_threaded directly. Using __libc_early_init and its initial flag, implementation of this variable is very straightforward. A future version may reset the flag during fork (but not in an inner namespace), or after joining all threads except one. Reviewed-by: DJ Delorie <dj@redhat.com>

Deprecated and removed features, and other changes affecting compatibility:
Remove --enable-obsolete-rpc configure flag Sun RPC was removed from glibc. This includes rpcgen program, librpcsvc, and Sun RPC headers. Also test for bug #20790 was removed (test for rpcgen). Backward compatibility for old programs is kept only for architectures and ABIs that have been added in or before version 2.28. libtirpc is mature enough, librpcsvc and rpcgen are provided in rpcsvc-proto project. NOTE: libnsl code depends on Sun RPC (installed libnsl headers use installed Sun RPC headers), thus --enable-obsolete-rpc was a dependency for --enable-obsolete-nsl (removed in a previous commit).

Linux: Remove <sys/sysctl.h> and the sysctl function Linux 5.5 remove the system call in commit 61a47c1ad3a4dc6882f01ebdc88138ac62d0df03 ("Linux: Remove <sys/sysctl.h>"). Therefore, the compat function is just a stub that sets ENOSYS. Due to SHLIB_COMPAT, new ports will not add the sysctl function anymore automatically. x32 already lacks the sysctl function, so an empty sysctl.c file is used to suppress it. Otherwise, a new compat symbol would be added. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* Using weak references to libpthread functions such as pthread_create

define pthread_create within libc.so.6 itself, so such checks will
always flag the program as multi-threaded. Applications should check

flavor of secure RPC.)
nss: Remove cryptographic key support from nss_files, nss_nis, nss_nisplus The interface has hard-coded buffer sizes and is therefore tied to DES. It also does not match current practice where different services on the same host use different key material. This change simplifies removal of the sunrpc code.

Changes to build and runtime requirements:
powerpc64le: raise GCC requirement to 7.4 for long double transition Add compiler feature tests to ensure we can build ieee128 long double. These test for -mabi=ieeelongdouble, -mno-gnu-attribute, and -Wno-psabi. Likewise, verify some compiler bugs have been addressed. These aren't helpful for building glibc, but may cause test failures when testing the new long double. See notes below from Raji. On powerpc64le, some older compiler versions give error for the function signbit() for 128-bit floating point types. This is fixed by PR83862 in gcc 8.0 and backported to gcc6 and gcc7. This patch adds a test to check compiler version to avoid compiler errors during make check. Likewise, test for -mno-gnu-attribute support which was On powerpc64le, a few files are built on IEEE long double mode (-mabi=ieeelongdouble), whereas most are built on IBM long double mode (-mabi=ibmlongdouble, the default for -mlong-double-128). Since binutils 2.31, linking object files with different long double modes causes errors similar to: ld: libc_pic.a(s_isinfl.os) uses IBM long double, libc_pic.a(ieee128-qefgcvt.os) uses IEEE long double. collect2: error: ld returned 1 exit status make[2]: *** [../Makerules:649: libc_pic.os] Error 1 The warnings are fair and correct, but in order for glibc to have support for both long double modes on powerpc64le, they have to be ignored. This can be accomplished with the use of -mno-gnu-attribute option when building the few files that require IEEE long double mode. However, -mno-gnu-attribute is not available in GCC 6, the minimum version required to build glibc, so this patch adds a test for this feature in powerpc64le builds, and fails early if it's not available.

Version 2.31
Major new features:
Add feature test macro _ISOC2X_SOURCE. This patch starts preparation for C2X support in glibc headers by adding a feature test macro _ISOC2X_SOURCE and corresponding __GLIBC_USE (ISOC2X). (I chose to use the newer __GLIBC_USE style for this rather than the older __USE_* macros tested with #ifdef.) As with other such macros, C2X features are also enabled by compiling for a standard newer than C17, or by using _GNU_SOURCE. This patch does not itself enable anything new in the headers for C2X; that is to be done in followup patches. (For example, most of the TS 18661-1 functions should be declared for C2X without any __STDC_WANT_IEC_60559_BFP_EXT__ being needed, but the ones that 18661-1 adds to Annex F because of their close relation to IEEE 754 formats do still need the WANT macro in C2X.) Once C2X becomes an actual standard we'll presumably move to using the actual year in the feature test macro and __GLIBC_USE, with some period when both macro spellings are accepted, as was done with _ISOC9X_SOURCE. Tested for x86_64. * include/features.h (_ISOC2X_SOURCE): New feature test macro. Undefine and define to 1 if [_GNU_SOURCE]. (__GLIBC_USE_ISOC2X): New macro. Undefine and redefine depending on [_ISOC2X_SOURCE] and [__STDC_VERSION__ > 201710L]. (__USE_ISOC11): Also define to 1 if [_ISOC2X_SOURCE]. (__USE_ISOC99): Likewise.

* The GNU C Library now supports a feature test macro _ISOC2X_SOURCE to
enable features from the draft ISO C2X standard. Only some features from
this draft standard are supported by the GNU C Library, and as the draft
is under active development, the set of features enabled by this macro is
liable to change. Features from C2X are also enabled by _GNU_SOURCE, or
by compiling with "gcc -std=gnu2x".

Add tgmath.h macros for narrowing functions. When adding some of the TS 18661 narrowing functions for glibc 2.28, I deferred adding corresponding <tgmath.h> support because of unresolved questions about the specification for those type-generic macros, especially in relation to _FloatN and _FloatNx types. Those issues are now clarified in the response to Clarification Request 13 to TS 18661-3, and this patch adds the deferred tgmath.h support. As with other tgmath.h macros, there are fairly straightforward implementations based on __builtin_tgmath for GCC 8 and later, which result in exactly the right function being called in each case, and more complicated implementations for GCC 7 and earlier, which generally result in a function being called whose arguments have the right format (i.e. an alias for the right function), but which might not be exactly the function name specified by TS 18661. In one case with older compilers (f32x* macros, where the type _Float64x exists and all the arguments have type _Float32 or _Float32x), there is a further relaxation and the function called may have arguments narrower than the one specified by the TS, but still wide enough to represent the arguments exactly, so the result of the call is unchanged (as this does not affect any case where rounding of integer arguments might be involved). With GCC 6 or before this is inherently unavoidable (but still harmless and not detectable by how the compiled program behaves, unless it redefines the functions in question like the testcases do) because _Float32x and _Float64 are both typedefs for double in that case but the specified semantics result in different functions, with different argument formats, being called for those two argument types. Tests for the new macros are handled through gen-tgmath-tests.py, which deals with the special-case handling for older GCC. Tested as follows: with the full glibc testsuite on x86_64 and x86 (with GCC 6, 7 and 8); with the math/ tests on aarch64 and arm (with GCC 6, 7 and 8); with build-many-glibcs.py (with GCC 6, 7 and 9). * math/tgmath.h [__HAVE_FLOAT128X]: Give error.

mode, the AD bit, as provided by the name server, is available to
applications which call res_search and related functions. In the default
mode, the AD bit is not set in queries, and it is automatically cleared in
responses, indicating a lack of DNSSEC validation. (Therefore, the name
servers and the network path to them are treated as untrusted.)

Deprecated and removed features, and other changes affecting compatibility:
Make totalorder and totalordermag functions take pointer arguments. The resolution of C floating-point Clarification Request 25 <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2397.htm#dr_25> is that the totalorder and totalordermag functions should take pointer arguments, and this has been adopted in C2X (with const added; note that the integration of this change into C2X is present in the C standard git repository but postdates the most recent public PDF draft). This patch updates glibc accordingly. As a defect resolution, the API is changed unconditionally rather than supporting any sort of TS 18661-1 mode for compilation with the old version of the API. There are compat symbols for existing binaries that pass floating-point arguments directly. As a consequence of changing to pointer arguments, there are no longer type-generic macros in tgmath.h for these functions. Because of the fairly complicated logic for creating libm function aliases and determining the set of aliases to create in a given glibc configuration, rather than duplicating all that in individual source files to create the versioned and compat symbols, the source files for the various versions of totalorder functions are set up to redefine weak_alias before using libm_alias_* macros to create the symbols required. In turn, this requires creating a separate alias for each symbol version pointing to the same implementation (see binutils bug <https://sourceware.org/bugzilla/show_bug.cgi?id=23840>), which is done automatically using __COUNTER__. (As I noted in <https://sourceware.org/ml/libc-alpha/2018-10/msg00631.html>, it might well make sense for glibc's symbol versioning macros to do that alias creation with __COUNTER__ themselves, which would somewhat simplify the logic in the totalorder source files.) It is of course desirable to test the compat symbols. I did this with the generic libm-test machinery, but didn't wish to duplicate the actual tables of test inputs and outputs, and thought it risky to attempt to have a single object file refer to both default and compat versions of the same function in order to test them together. Thus, I created libm-test-compat_totalorder.inc and libm-test-compat_totalordermag.inc which include the generated .c files (with the processed version of those tables of inputs) from the non-compat tests, and added appropriate dependencies. I think this provides sufficient test coverage for the compat symbols without also needing to make the special ldbl-96 and ldbl-128ibm tests (of peculiarities relating to the representations of those formats that can't be covered in the generic tests) run for the compat symbols. Tests of compat symbols need to be internal tests, meaning _ISOMAC is not defined. Making some libm-test tests into internal tests showed up two other issues. GCC diagnoses duplicate macro definitions of __STDC_* macros, including __STDC_WANT_IEC_60559_TYPES_EXT__; I added an appropriate conditional and filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91451> for this issue. On ia64, include/setjmp.h ends up getting included indirectly from libm-symbols.h, resulting in conflicting definitions of the STR macro (also defined in libm-test-driver.c); I renamed the macros in include/setjmp.h. (It's arguable that we should have common internal headers used everywhere for stringizing and concatenation macros.)

As of this release, callers of gettimeofday with a non-null 'tzp' argument
should expect to receive a 'struct timezone' whose tz_minuteswest and
tz_dsttime fields are zero. (For efficiency reasons, this does not always
happen on a few Linux-based ports. This will be corrected in a future
release.)
All callers should supply a null pointer for the 'tzp' argument to
gettimeofday. For accurate information about the time zone associated
with the current time, use the localtime function.
gettimeofday itself is obsolescent according to POSIX. We have no plans
to remove access to this function, but portable programs should consider
using clock_gettime instead.
Use clock_settime to implement stime; withdraw stime. Unconditionally, on all ports, use clock_settime to implement stime, not settimeofday or a direct syscall. Then convert stime into a compatibility symbol and remove its prototype from time.h. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.

Use clock_settime to implement settimeofday. Unconditionally, on all ports, use clock_settime to implement settimeofday. Remove sysdeps/unix/clock_settime.c, which implemented clock_settime by calling settimeofday; new OS ports must henceforth provide a real implementation of clock_settime. Hurd had a real implementation of settimeofday but not of clock_settime; this patch converts it into an implementation of clock_settime. It only supports CLOCK_REALTIME and microsecond resolution; Hurd/Mach does not appear to have any support for finer-resolution clocks. The vestigial "set time zone" feature of settimeofday complicates the generic settimeofday implementation a little. The only remaining uses of this feature that aren't just bugs, are using it to inform the Linux kernel of the offset between the hardware clock and UTC, on systems where the hardware clock doesn't run in UTC (usually because of dual-booting with Windows). There currently isn't any other way to do this. However, the callers that do this call settimeofday with _only_ the timezone argument non-NULL. Therefore, glibc's new behavior is: callers of settimeofday must supply one and only one of the two arguments. If both arguments are non-NULL, or both arguments are NULL, the call fails and sets errno to EINVAL. When only the timeval argument is supplied, settimeofday calls __clock_settime(CLOCK_REALTIME), same as stime. When only the timezone argument is supplied, settimeofday calls a new internal function called __settimezone. On Linux, only, this function will pass the timezone structure to the settimeofday system call. On all other operating systems, and on Linux architectures that don't define __NR_settimeofday, __settimezone is a stub that always sets errno to ENOSYS and returns -1. The settimeoday syscall is enabled on Linux by the flag COMPAT_32BIT_TIME, which is an option to either 32-bits ABIs or COMPAT builds (defined usually by 64-bit kernels that want to support 32-bit ABIs, such as x86). The idea to future 64-bit time_t only ABIs is to not provide settimeofday syscall. The same semantics are implemented for Linux/Alpha's GLIBC_2.0 compat symbol for settimeofday. There are no longer any internal callers of __settimeofday, so the internal prototype is removed.

* The settimeofday function can still be used to set a system-wide time
zone when the operating system supports it. This is because the Linux
kernel reused the API, on some architectures, to describe a system-wide
time-zone-like offset between the software clock maintained by the kernel,
and the "RTC" clock that keeps time when the system is shut down.
However, to reduce the odds of this offset being set by accident,
settimeofday can no longer be used to set the time and the offset
simultaneously. If both of its two arguments are non-null, the call
will fail (setting errno to EINVAL).
Callers attempting to set this offset should also be prepared for the call
to fail and set errno to ENOSYS; this already happens on the Hurd and on
some Linux architectures. The Linux kernel maintainers are discussing a
more principled replacement for the reused API. After a replacement
becomes available, we will change settimeofday to fail with ENOSYS on all
platforms when its 'tzp' argument is not a null pointer.
Revise NEWS description of changes to gettimeofday etc. Mostly English grammar and style improvements. The bullet list is reorganized a little for clarity. The details of exactly which Linux-based ports still report system-wide time zone information from gettimeofday has been removed, as this is not intended to be something people should rely on. Also clarify the deprecation of older SPARC ISAs, based on the fact that “SPARC version 7” is actually the very first version of the SPARC ISA (Sun Microsystems was very fond of letting the marketing department pick version numbers).

* SPARC ISA v7 is no longer supported. v8 is still supported, but only if
the optional CAS instruction is implemented (for instance, LEON processors
are still supported, but SuperSPARC processors are not).
Consolidate and deprecate ftime ftime is an obsolete variation on gettimeofday, offering only millisecond time resolution; it was probably a system call in ooold versions of BSD Unix. For historic reasons, we had three implementations of it. These are all consolidated into time/ftime.c, and then the function is deprecated. For some reason, the implementation of ftime in terms of gettimeofday was rounding rather than truncating microseconds to milliseconds. In all the other places where we use a higher-resolution time function to implement a lower-resolution one, we truncate. ftime is changed to match, just for tidiness' sake. Like gettimeofday, ftime tries to report the time zone, and using that information is always a bug. This patch dummies out the reported timezone information; the timezone and dstflag fields of the returned "struct timeb" will always be zero.

configurations.
Remove 32 bit sparc v7 support The patch is straighforward: - The sparc32 v8 implementations are moved as the generic ones. - A configure test is added to check for either __sparc_v8__ or __sparc_v9__. - The triple names are simplified and sparc implies sparcv8. The idea is to keep support on sparcv8 architectures that does support CAS instructions, such as LEON3/LEON4. Checked on a sparcv9-linux-gnu and sparc64-linux-gnu.

Lazy binding failures during dlopen/dlclose must be fatal [BZ #24304] If a lazy binding failure happens during the execution of an ELF constructor or destructor, the dynamic loader catches the error and reports it using the dlerror mechanism. This is undesirable because there could be other constructors and destructors that need processing (which are skipped), and the process is in an inconsistent state at this point. Therefore, we have to issue a fatal dynamic loader error error and terminate the process. Note that the _dl_catch_exception in _dl_open is just an inner catch, to roll back some state locally. If called from dlopen, there is still an outer catch, which is why calling _dl_init via call_dl_init and a no-exception is required and cannot be avoiding by moving the _dl_init call directly into _dl_open. _dl_fini does not need changes because it does not install an error handler, so errors are already fatal there.

* If a lazy binding failure happens during dlopen, during the execution of
an ELF constructor, the process is now terminated. Previously, the
dynamic loader would return NULL from dlopen, with the lazy binding error
captured in a dlerror message. In general, this is unsafe because
resetting the stack in an arbitrary function call is not possible.
Add NEWS entry about the change in handling of PT_GNU_STACK on MIPS The change was introduced in: commit 33bc9efd91de1b14354291fc8ebd5bce96379f12 Author: Dragan Mladjenovic <dmladjenovic@wavecomp.com> Date: Fri Aug 23 16:38:04 2019 +0000 mips: Force RWX stack for hard-float builds that can run on pre-4.8 kernels and probably requires a small explanation.

* For MIPS hard-float ABIs, the GNU C Library will be configured to need an
executable stack unless explicitly configured at build time to require
minimum kernel version 4.8 or newer. This is because executing
floating-point branches on a non-executable stack on Linux kernels prior to
4.8 can lead to application crashes for some MIPS configurations. While
currently PT_GNU_STACK is not widely used on MIPS, future releases of GCC are
expected to enable non-executable stack by default with PT_GNU_STACK by
default and is thus likely to trigger a crash on older kernels.
The GNU C Library can be built with --enable-kernel=4.8.0 in order to keep a
non-executable stack while dropping support for older kernels.
Add NEWS entry about 64-bit time_t syscall use on 32-bit targets This internal change ideally should not affect the public API or ABI, but there is a widespread use of seccomp sandboxes, even on 32-bit targets, that don't handle new Linux syscall usage well, so it's worth mentioning in the NEWS.

* System call wrappers for time system calls now use the new time64 system
calls when available. On 32-bit targets, these wrappers attempt to call
the new system calls first and fall back to the older 32-bit time system
calls if they are not present. This may cause issues in environments
that cannot handle unsupported system calls gracefully by returning
-ENOSYS. Seccomp sandboxes are affected by this issue.

Changes to build and runtime requirements:
Linux: Use system call tables during build Use <arch-syscall.h> instead of <asm/unistd.h> to obtain the system call numbers. A few direct includes of <asm/unistd.h> need to be removed (if the system call numbers are already provided indirectly by <sysdep.h>) or replaced with <sys/syscall.h>. Current Linux headers for alpha define the required system call names, so most of the _NR_* hacks are no longer needed. For the 32-bit arm architecture, eliminate the INTERNAL_SYSCALL_ARM macro, now that we have regular system call names for cacheflush and set_tls. There are more such cleanup opportunities for other architectures, but these cleanups are required to avoid macro redefinition errors during the build. For ia64, it is desirable to use <asm/break.h> directly to obtain the break number for system calls (which is not a system call number itself). This requires replacing __BREAK_SYSCALL with __IA64_BREAK_SYSCALL because the former is defined as an alias in <asm/unistd.h>, but not in <asm/break.h>.

2019-04-21 11:39:25 +00:00
* Memory allocation functions malloc, calloc, realloc, reallocarray, valloc,
pvalloc, memalign, and posix_memalign fail now with total object size
larger than PTRDIFF_MAX. This is to avoid potential undefined behavior with
pointer subtraction within the allocated object, where results might
overflow the ptrdiff_t type.
ld.so: Support moving versioned symbols between sonames [BZ #24741] This change should be fully backwards-compatible because the old code aborted the load if a soname mismatch was encountered (instead of searching further for a matching symbol). This means that no different symbols are found. The soname check was explicitly disabled for the skip_map != NULL case. However, this only happens with dl(v)sym and RTLD_NEXT, and those lookups do not come with a verneed entry that could be used for the check. The error check was already explicitly disabled for the skip_map != NULL case, that is, when dl(v)sym was called with RTLD_NEXT. But _dl_vsym always sets filename in the struct r_found_version argument to NULL, so the check was not active anyway. This means that symbol lookup results for the skip_map != NULL case do not change, either.
2019-06-28 08:12:50 +00:00
* The dynamic linker no longer refuses to load objects which reference
versioned symbols whose implementation has moved to a different soname
since the object has been linked. The old error message, symbol
FUNCTION-NAME, version SYMBOL-VERSION not defined in file DSO-NAME with
link time reference, is gone.

* Add new POSIX-proposed pthread_cond_clockwait, pthread_mutex_clocklock,
pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and sem_clockwait
functions. These behave similarly to their "timed" equivalents, but also
accept a clockid_t parameter to determine which clock their timeout should
be measured against. All functions allow waiting against CLOCK_MONOTONIC
and CLOCK_REALTIME. The decision of which clock to be used is made at the
time of the wait (unlike with pthread_condattr_setclock, which requires
the clock choice at initialization time).

on kernels that do not support the copy_file_range system call, and if
this function returns ENOSYS, they will need to use their own fallback.

rt: Turn forwards from librt to libc into compat symbols [BZ #24194] As the result of commit 6e6249d0b461b952d0f544792372663feb6d792a ("BZ#14743: Move clock_* symbols from librt to libc."), in glibc 2.17, clock_gettime, clock_getres, clock_settime, clock_getcpuclockid, clock_nanosleep were added to libc, and the file rt/clock-compat.c was added with forwarders to the actual implementations in libc. These forwarders were wrapped in #if SHLIB_COMPAT (librt, GLIBC_2_2, GLIBC_2_17) so that they are not present for newer architectures (such as powerpc64le) with a 2.17 or later ABI baseline. But the forwarders were not marked as compatibility symbols. As a result, on older architectures, historic configure checks such as AC_CHECK_LIB(rt, clock_gettime) still cause linking against librt, even though this is completely unnecessary. It also creates a needless porting hazard because architectures behave differently when it comes to symbol availability. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* The functions clock_gettime, clock_getres, clock_settime,

since glibc 2.17.

Remove obsolete, never-implemented XSI STREAMS declarations The stub implementations are turned into compat symbols. Linux actually has two reserved system call numbers (for getpmsg and putpmsg), but these system calls have never been implemented, and there are no plans to implement them, so this patch replaces the wrappers with the generic stubs. According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>, the presence of the XSI STREAMS declarations is a minor portability hazard because they are not actually implemented. This commit does not change the TIRPC support code in sunrpc/rpc_svcout.c. It uses additional XTI functionality and therefore never worked with glibc. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

Remove support for PowerPC SPE extension (powerpc*-*-*gnuspe*). GCC 9 dropped support for the SPE extensions to PowerPC, which means powerpc*-*-*gnuspe* configurations are no longer buildable with that compiler. This ISA extension was peculiar to the “e500” line of embedded PowerPC chips, which, as far as I can tell, are no longer being manufactured, so I think we should follow suit. This patch was developed by grepping for “e500”, “__SPE__”, and “__NO_FPRS__”, and may not eliminate every vestige of SPE support. Most uses of __NO_FPRS__ are left alone, as they are relevant to normal embedded PowerPC with soft-float. * sysdeps/powerpc/preconfigure: Error out on powerpc-*-*gnuspe* host type. * scripts/build-many-glibcs.py: Remove powerpc-*-linux-gnuspe and powerpc-*-linux-gnuspe-e500v1 from list of build configurations. * sysdeps/powerpc/powerpc32/e500: Recursively delete. * sysdeps/unix/sysv/linux/powerpc/powerpc32/e500: Recursively delete. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/context-e500.h: Delete. * sysdeps/powerpc/fpu_control.h: Remove SPE variant.

arm: Remove ioperm/iopl/inb/inw/inl/outb/outw/outl support Linux only supports the required ISA sysctls on StrongARM devices, which are armv4 and no longer tested during glibc development and probably bit-rotted by this point.

Changes to build and runtime requirements:
Require GCC 6.2 or later to build glibc. As discussed during development for glibc 2.29, when we increased the required minimum GCC version for building glibc to GCC 5, working purely based on the times at which such requirements have been increased in the past it would be appropriate for glibc 2.30 to require GCC 6 (matching GCC 4.9 having been required for glibc 2.26). Naming 6.2 specifically as the minimum version then means a separate version requirement no longer needs to be specified for powerpc64le. Thus, this patch increases the minimum to 6.2, removing the documentation of the separate requirement for powerpc64le. It does not remove the powerpc64le configure test, or any __GNUC_PREREQ that could be removed as not being in installed headers or files shared with gnulib; I think such cleanups are best done separately. Tested for x86_64. * configure.ac (libc_cv_compiler_ok): Require GCC 6.2 or later. * configure: Regenerated. * manual/install.texi (Tools for Compilation): Update minimum GCC version. * INSTALL: Regenerated.
2019-02-01 16:27:44 +00:00

in the lower 32 bits of the 64-bit RDX register with non-zero upper
32 bits. When it happened with the sign bit of RDX register set,
memcmp gave the wrong result since it treated the size argument as
zero. Reported by H.J. Lu.

Add convenience target 'install-locale-files'. The convenience install target 'install-locale-files' is created to allow distributions to install all of the SUPPORTED locales as files instead of into the locale-archive. You invoke the new convenience target like this: make localedata/install-locale-files DESTDIR=<prefix>
2018-07-26 14:14:55 +00:00
* A new convenience target has been added for distribution maintainers
to build and install all locales as directories with files. The new
target is run by issuing the following command in your build tree:
'make localedata/install-locale-files', with an optional DESTDIR
to set the install root if you wish to install into a non-default
configured location.

Add new pow implementation The algorithm is exp(y * log(x)), where log(x) is computed with about 1.3*2^-68 relative error (1.5*2^-68 without fma), returning the result in two doubles, and the exp part uses the same algorithm (and lookup tables) as exp, but takes the input as two doubles and a sign (to handle negative bases with odd integer exponent). The __exp1 internal symbol is no longer necessary. There is separate code path when fma is not available but the worst case error is about 0.54 ULP in both cases. The lookup table and consts for log are 4168 bytes. The .rodata+.text is decreased by 37908 bytes on aarch64. The non-nearest rounding error is less than 1 ULP.

powerpc: Only enable TLE with PPC_FEATURE2_HTM_NOSC Linux from 3.9 through 4.2 does not abort HTM transaction on syscalls, instead it suspend and resume it when leaving the kernel. The side-effects of the syscall will always remain visible, even if the transaction is aborted. This is an issue when transaction is used along with futex syscall, on pthread_cond_wait for instance, where the futex call might succeed but the transaction is rolled back leading the pthread_cond object in an inconsistent state. Glibc used to prevent it by always aborting a transaction before issuing a syscall. Linux 4.2 also decided to abort active transaction in syscalls which makes the glibc workaround superfluous. Worse, glibc transaction abortion leads to a performance issue on recent kernels where the HTM state is saved/restore lazily (v4.9). By aborting a transaction on every syscalls, regardless whether a transaction has being initiated before, GLIBS makes the kernel always save/restore HTM state (it can not even lazily disable it after a certain number of syscall iterations). Because of this shortcoming, Transactional Lock Elision is just enabled when it has been explicitly set (either by tunables of by a configure switch) and if kernel aborts HTM transactions on syscalls (PPC_FEATURE2_HTM_NOSC). It is reported that using simple benchmark [1], the context-switch is about 5% faster by not issuing a tabort in every syscall in newer kernels. Checked on powerpc64le-linux-gnu with 4.4.0 kernel (Ubuntu 16.04). * NEWS: Add note about new TLE support on powerpc64le. * sysdeps/powerpc/nptl/tcb-offsets.sym (TM_CAPABLE): Remove. * sysdeps/powerpc/nptl/tls.h (tcbhead_t): Rename tm_capable to __ununsed1.

* For powercp64le ABI, Transactional Lock Elision is now enabled iff kernel
indicates that it will abort the transaction prior to entering the kernel
(PPC_FEATURE2_HTM_NOSC on hwcap2). On older kernels the transaction is
suspended, and this caused some undefined side-effects issues by aborting
transactions manually. Glibc avoided it by abort transactions manually on
each syscall, but it lead to performance issues on newer kernels where the
HTM state is saved and restore lazily (the state being saved even when the
process actually does not use HTM).

strftime: Set the default width of "%Ey" to 2 [BZ #23758] In Japanese locales, strftime's alternative year format (%Ey) produces a year numbered within a time period called an _era_. A new era typically begins when a new emperor is enthroned. The result of "%Ey" is therefore usually a one- or two-digit number. Many programs that display Japanese era dates assume that the era year is two digits wide. To improve how these programs display dates during the first nine years of a new era, change "%Ey" to pad one- digit numbers on the left with a zero. This change applies to all locales. It is expected to be harmless for other locales that use the alternative year format (e.g. lo_LA and th_TH, in which "%Ey" produces the year of the Buddhist calendar) as those calendars' year numbers are already more than two digits wide, and this is not expected to change. This change needs to be in place before 2019-05-01 CE, as a new era is scheduled to begin on that date.

* strftime's default formatting of a locale's alternative year (%Ey)
has been changed to zero-pad the year to a minimum of two digits,
like "%y". This improves the display of Japanese era years during
the first nine years of a new era, and is expected to be harmless
for all other locales (only Japanese locales regularly have
alternative year numbers less than 10). Zero-padding can be
overridden with the '_' or '-' flags (which are GNU extensions).
strftime: Pass the additional flags from "%EY" to "%Ey" [BZ #24096] The full representation of the alternative calendar year (%EY) typically includes an internal use of "%Ey". As a GNU extension, apply any flags on "%EY" (e.g. "%_EY", "%-EY") to the internal "%Ey", allowing users of "%EY" to control how the year is padded.

Fix sys/procfs.h pr_uid, pr_gid type (bug 23649). As noted in <https://sourceware.org/ml/libc-alpha/2018-09/msg00178.html>, glibc's sys/procfs.h headers for microblaze, mips (n64), nios2 and riscv have incorrect types for the pr_uid and pr_gid members of struct elf_prpsinfo (as does the generic Linux version, but nothing uses that). This patch fixes those headers to use unsigned int. The generic Linux version is also fixed, but I do *not* recommend making new architectures use it yet. Rather, I think it should be reworked to look more like a copy of the AArch64 version, but with a new <bits/procfs.h> header included to provide register set definitions; <bits/procfs.h> would then be architecture-specific while many architectures could use the generic <sys/procfs.h>. This fix is deliberately separate from any reworking to use a generic header more, since it's possible there could be uses for backporting this fix but not for backporting a subsequent cleanup. Tested with build-many-glibcs.py. This of course doesn't provide much validation of the structure layout; if the Linux kernel is fixed so that "#include <linux/elfcore.h>" actually compiles with the headers from "make headers_install" (and if the layout in both headers is meant to be the same, whatever ABI we are building for), I have a test that can be added to glibc to check the layout against that from the Linux kernel.

* The type of the pr_uid and pr_gid members of struct elf_prpsinfo, defined
in <sys/procfs.h>, has been corrected to match the type actually used by
the Linux kernel. This affects the size and layout of that structure on
MicroBlaze, MIPS (n64 ABI only), Nios II and RISC-V.
Fix MIPS n32 pr_sigpend, pr_sighold, pr_flag type (bug 23656). As discussed at <https://sourceware.org/ml/libc-alpha/2018-09/msg00191.html> and followup discussions, the MIPS n32 definitions of pr_sigpend and pr_sighold in struct elf_prstatus, and pr_flag in struct elf_prpsinfo, are wrong to use unsigned long long int; actual n32 core dumps use a 32-bit type there, so userspace unsigned long int is correct for all MIPS ABIs. This patch removes the conditionals (also thereby aligning the structures with other architectures and so facilitating future unification of different versions of this header). Tested with build-many-glibcs.py for its MIPS configurations. [BZ #23656] * sysdeps/unix/sysv/linux/mips/sys/procfs.h (struct elf_prstatus): Remove [_MIPS_SIM = _ABIN32] conditional case.

Use C99-compliant scanf under _GNU_SOURCE with modern compilers. The only difference between noncompliant and C99-compliant scanf is that the former accepts the archaic GNU extension '%as' (also %aS and %a[...]) meaning to allocate space for the input string with malloc. This extension conflicts with C99's use of %a as a format _type_ meaning to read a floating-point number; POSIX.1-2008 standardized equivalent functionality using the modifier letter 'm' instead (%ms, %mS, %m[...]). The extension was already disabled in most conformance modes: specifically, any mode that doesn't involve _GNU_SOURCE and _does_ involve either strict conformance to C99 or loose conformance to both C99 and POSIX.1-2001 would get the C99-compliant scanf. With compilers new enough to use -std=gnu11 instead of -std=gnu89, or equivalent, that includes the default mode. With this patch, we now provide C99-compliant scanf in all configurations except when _GNU_SOURCE is defined *and* __STDC_VERSION__ or __cplusplus (whichever is relevant) indicates C89/C++98. This leaves the old scanf available under e.g. -std=c89 -D_GNU_SOURCE, but removes it from e.g. -std=gnu11 -D_GNU_SOURCE (it was already not present under -std=gnu11 without -D_GNU_SOURCE) and from -std=gnu89 without -D_GNU_SOURCE. There needs to be an internal override so we can compile the noncompliant scanf itself. This is the same problem we had when we removed 'gets' from _GNU_SOURCE and it's dealt with the same way: there's a new __GLIBC_USE symbol, DEPRECATED_SCANF, which defaults to off under the appropriate conditions for external code, but can be overridden by individual files within stdio. We also run into problems with PLT bypass for internal uses of sscanf, because libc_hidden_proto uses __REDIRECT and so does the logic in stdio.h for choosing which implementation of scanf to use; __REDIRECT isn't transitive, so include/stdio.h needs to bridge the gap with a macro. As far as I can tell, sscanf is the only function in this family that's internally called by unrelated code. Finally, there are several tests in stdio-common that use the extension. bug21.c is a regression test for a crash; it still exercises the relevant code when changed to use %ms instead of %as. scanf14.c through scanf17.c are more complicated since they are actually testing the subtleties of the extension - under what circumstances is 'a' treated as a modifier letter, etc. I changed all of them to use %ms instead of %as as well, but duplicated scanf14.c and scanf16.c as scanf14a.c and scanf16a.c. These still use %as and are compiled with -std=gnu89 to access the old extension. A bunch of diagnostic overrides and manual workarounds for the old stdio.h behavior become unnecessary. Yay! * include/features.h (__GLIBC_USE_DEPRECATED_SCANF): New __GLIBC_USE parameter.

Add __attribute__ ((format (scanf))) to xscanf, xfscanf, xsscanf. * stdio-common/scanf15.c, stdio-common/scanf17.c: No need to override feature selection macros or provide definitions of u_char etc. * stdio-common/Makefile (tests): Add scanf14a and scanf16a. (CFLAGS-scanf15.c, CFLAGS-scanf17.c): Remove. (CFLAGS-scanf14a.c, CFLAGS-scanf16a.c): New. Compile these files with -std=gnu89.
2018-02-10 16:58:35 +00:00
* An archaic GNU extension to scanf, under which '%as', '%aS', and '%a[...]'
meant to scan a string and allocate space for it with malloc, is now
restricted to programs compiled in C89 or C++98 mode with _GNU_SOURCE
defined. This extension conflicts with C99's use of '%a' to scan a
hexadecimal floating-point number, which is now available to programs
compiled as C99 or C++11 or higher, regardless of _GNU_SOURCE.
POSIX.1-2008 includes the feature of allocating a buffer for string input
with malloc, using the modifier letter 'm' instead. Programs using
'%as', '%aS', or '%a[...]' with the old GNU meaning should change to
'%ms', '%mS', or '%m[...]' respectively. Programs that wish to use the
C99 '%a' no longer need to avoid _GNU_SOURCE.
GCC's -Wformat warnings can detect most uses of this extension, as long
as all functions that call vscanf, vfscanf, or vsscanf are annotated with
__attribute__ ((format (scanf, ...))).

Changes to build and runtime requirements:
Patch to require Python 3.4 or later to build glibc. This patch makes Python 3.4 or later a required tool for building glibc, so allowing changes of awk, perl etc. code used in the build and test to Python code without any such changes needing makefile conditionals or to handle older Python versions. This patch makes the configure test for Python check the version and give an error if Python is missing or too old, and removes makefile conditionals that are no longer needed. It does not itself convert any code from another language to Python, and does not remove any compatibility with older Python versions from existing scripts. Tested for x86_64. * configure.ac (PYTHON_PROG): Use AC_CHECK_PROG_VER. Set critic_missing for versions before 3.4. * configure: Regenerated. * manual/install.texi (Tools for Compilation): Document requirement for Python to build glibc. * INSTALL: Regenerated. * Rules [PYTHON]: Make code unconditional. * benchtests/Makefile [PYTHON]: Likewise. * conform/Makefile [PYTHON]: Likewise. * manual/Makefile [PYTHON]: Likewise. * math/Makefile [PYTHON]: Likewise.

Require GCC 5 or later to build glibc (bug 23993). We know that building glibc with GCC 4.9 is broken on various platforms (bug 23993). As it's more than a year since we last increased the minimum GCC version to build glibc, this patch changes the requirement to be GCC 5 or later (indeed, based on 4.9 having been required for building 2.26, it would be consistent in terms of timing to require GCC 6 or later from the 2.30 release onwards). It deliberately just updates the configure test and corresponding documentation, leaving removal of no-longer-needed __GNUC_PREREQ tests for a separate patch. In the NEWS entry, the requirement for a newer GCC version for powerpc64le is reiterated (as in the entry for the 4.9 requirement in 2.26) to avoid suggesting the version requirement there has gone down. (If that version goes up further as part of support for binary128 long double, of course the wording would change at that time.) Tested for x86_64. [BZ #23993] * configure.ac (libc_cv_compiler_ok): Require GCC 5 or later. * configure: Regenerated. * manual/install.texi (Tools for Compilation): Update minimum GCC version. * INSTALL: Regenerated.

* On most architectures, GCC 5 or later is required to build the GNU C
Library. (On powerpc64le, GCC 6.2 or later is still required, as before.)
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library.

CVE-2016-10739: getaddrinfo: Fully parse IPv4 address strings [BZ #20018] The IPv4 address parser in the getaddrinfo function is changed so that it does not ignore trailing whitespace and all characters after it. For backwards compatibility, the getaddrinfo function still recognizes legacy name syntax, such as 192.000.002.010 interpreted as 192.0.2.8 (octal). This commit does not change the behavior of inet_addr and inet_aton. gethostbyname already had additional sanity checks (but is switched over to the new __inet_aton_exact function for completeness as well). To avoid sending the problematic query names over DNS, commit 6ca53a2453598804a2559a548a08424fca96434a ("resolv: Do not send queries for non-host-names in nss_dns [BZ #24112]") is needed.

Major new features:
Update NEWS with ISO 14651 update information.
2018-07-27 19:56:24 +00:00
* The localization data for ISO 14651 is updated to match the 2016
Edition 4 release of the standard, this matches data provided by
Unicode 9.0.0. This update introduces significant improvements to the
collation of Unicode characters. This release deviates slightly from
the standard in that the collation element ordering for lowercase and
uppercase LATIN script characters is adjusted to ensure that regular
expressions with ranges like [a-z] and [A-Z] don't interleave e.g. A
is not matched by [a-z]. With the update many locales have been
updated to take advantage of the new collation information. The new
collation information has increased the size of the compiled locale
archive or binary locales.

* The GNU C Library can now be compiled with support for Intel CET, AKA
Intel Control-flow Enforcement Technology. When the library is built
with --enable-cet, the resulting glibc is protected with indirect
branch tracking (IBT) and shadow stack (SHSTK). CET-enabled glibc is
compatible with all existing executables and shared libraries. This
feature is currently supported on i386, x86_64 and x32 with GCC 8 and
binutils 2.29 or later. Note that CET-enabled glibc requires CPUs
capable of multi-byte NOPs, like x86-64 processors as well as Intel

Pentium Pro or newer. NOTE: --enable-cet has been tested for i686,
x86_64 and x32 on non-CET processors. --enable-cet has been tested
for x86_64 and x32 on CET SDVs, but Intel CET support hasn't been
validated for i686.

libc-abis: Define ABSOLUTE ABI [BZ #19818][BZ #23307] Define a new ABSOLUTE ABI for static linker's use with EI_ABIVERSION where correct absolute (SHN_ABS) symbol run-time load semantics is required. This way it can be ensured at static link time that a program or DSO will not suffer from previous semantics where absolute symbols were relocated by the base address, or symbols whose `st_value' is zero silently ignored leading to a confusing "undefined symbol" error message at load time, and instead "ELF file ABI version invalid" is printed with old dynamic loaders, making it clear that there is an ABI version incompatibility. [BZ #19818] [BZ #23307] * libc-abis (ABSOLUTE): New ABI. * sysdeps/unix/sysv/linux/mips/libc-abis (ABSOLUTE): New ABI. * NEWS: Mention the new ABI. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2018-07-05 17:06:43 +00:00
* The GNU C Library now has correct support for ABSOLUTE symbols
(SHN_ABS-relative symbols). Previously such ABSOLUTE symbols were
relocated incorrectly or in some cases discarded. The GNU linker can
make use of the newer semantics, but it must communicate it to the
dynamic loader by setting the ELF file's identification (EI_ABIVERSION
field) to indicate such support is required.
Bug 23308: Update to Unicode 11.0.0 Unicode 11.0.0 Support: Character encoding, character type info, and transliteration tables are all updated to Unicode 11.0.0, using the generator scripts contributed by Mike FABIAN (Red Hat).

Add narrowing add functions. This patch adds the narrowing add functions from TS 18661-1 to glibc's libm: fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64 for all configurations; f32addf64x, f32addf128, f64addf64x, f64addf128, f32xaddf64x, f32xaddf128, f64xaddf128 for configurations with _Float64x and _Float128; __nldbl_daddl for ldbl-opt. As discussed for the build infrastructure patch, tgmath.h support is deliberately deferred, and FP_FAST_* macros are not applicable without optimized function implementations. Function implementations are added for all relevant pairs of formats (including certain cases of a format and itself where more than one type has that format). The main implementations use round-to-odd, or a trivial computation in the case where both formats are the same or where the wider format is IBM long double (in which case we don't attempt to be correctly rounding). The sysdeps/ieee754/soft-fp implementations use soft-fp, and are used automatically for configurations without exceptions and rounding modes by virtue of existing Implies files. As previously discussed, optimized versions for particular architectures are possible, but not included. i386 gets a special version of f32xaddf64 to avoid problems with double rounding (similar to the existing fdim version), since this function must round just once without an intermediate rounding to long double. (No such special version is needed for any other function, because the nontrivial functions use round-to-odd, which does the intermediate computation with the rounding mode set to round-to-zero, and double rounding is OK except in round-to-nearest mode, so is OK for that intermediate round-to-zero computation.) mul and div will need slightly different special versions for i386 (using round-to-odd on long double instead of precision control) because of the possibility of inexact intermediate results in the subnormal range for double. To reduce duplication among the different function implementations, math-narrow.h gets macros CHECK_NARROW_ADD, NARROW_ADD_ROUND_TO_ODD and NARROW_ADD_TRIVIAL. In the trivial cases and for any architecture-specific optimized implementations, the overhead of the errno setting might be significant, but I think that's best handled through compiler built-in functions rather than providing separate no-errno versions in glibc (and likewise there are no __*_finite entry points for these function provided, __*_finite effectively being no-errno versions at present in most cases). Tested for x86_64 and x86, with both GCC 6 and GCC 7. Tested for mips64 (all three ABIs, both hard and soft float) and powerpc with GCC 7.

Add narrowing multiply functions. This patch adds the narrowing multiply functions from TS 18661-1 to glibc's libm: fmul, fmull, dmull, f32mulf64, f32mulf32x, f32xmulf64 for all configurations; f32mulf64x, f32mulf128, f64mulf64x, f64mulf128, f32xmulf64x, f32xmulf128, f64xmulf128 for configurations with _Float64x and _Float128; __nldbl_dmull for ldbl-opt.

Add renameat2 function [BZ #17662] The implementation falls back to renameat if renameat2 is not available in the kernel (or in the kernel headers) and the flags argument is zero. Without kernel support, a non-zero argument returns EINVAL, not ENOSYS. This mirrors what the kernel does for invalid renameat2 flags.
2018-07-05 16:59:02 +00:00
* The renameat2 function has been added, a variant of the renameat function
which has a flags argument. If the flags are zero, the renameat2 function
acts like renameat. If the flag is not zero and there is no kernel
support for renameat2, the function will fail with an errno value of
EINVAL. This is different from the existing gnulib function renameatu,
which performs a plain rename operation in case of a RENAME_NOREPLACE
flags and a non-existing destination (and therefore has a race condition
that can clobber the destination inadvertently).

getnameinfo. (getaddrinfo calls with non-ASCII names and AI_IDN will fail
with an encoding error.) Flags which used to change the IDN encoding and
decoding behavior (AI_IDN_ALLOW_UNASSIGNED, AI_IDN_USE_STD3_ASCII_RULES,
NI_IDN_ALLOW_UNASSIGNED, NI_IDN_USE_STD3_ASCII_RULES) have been

Improve DST handling (Bug 23102, Bug 21942, Bug 18018, Bug 23259). This commit improves DST handling significantly in the following ways: firstly is_dst () is overhauled to correctly process DST sequences that would be accepted given the ELF gABI. This means that we actually now accept slightly more sequences than before. Now we accept $ORIGIN$ORIGIN, but in the past we accepted only $ORIGIN\0 or $ORIGIN/..., but this kind of behaviour results in unexpected and uninterpreted DST sequences being used as literal search paths leading to security defects. Therefore the first step in correcting this defect is making is_dst () properly account for all DSTs and making the function context free in the sense that it counts DSTs without knowledge of path, or AT_SECURE. Next, _dl_dst_count () is also simplified to count all DSTs regardless of context. Then in _dl_dst_substitute () we reintroduce context-dependent processing for such things as AT_SECURE handling. At the level of _dl_dst_substitute we can have access to things like the true start of the string sequence to validate $ORIGIN-based paths rooted in trusted directories. Lastly, we tighten up the accepted sequences in AT_SECURE, and avoid leaving known unexpanded DSTs, this is noted in the NEWS entry. Verified with a sequence of 68 tests on x86_64 that cover non-AT_SECURE and AT_SECURE testing using a sysroot (requires root to run). The tests cover cases for bug 23102, bug 21942, bug 18018, and bug 23259. These tests are not yet appropriate for the glibc regression testsuite, but with the upcoming test-in-container testing framework it should be possible to include these tests upstream soon. See the mailing list for the tests: https://www.sourceware.org/ml/libc-alpha/2018-06/msg00251.html

* Parsing of dynamic string tokens in DT_RPATH, DT_RUNPATH, DT_NEEDED,
DT_AUXILIARY, and DT_FILTER has been expanded to support the full
range of ELF gABI expressions including such constructs as
'$ORIGIN$ORIGIN' (if valid). For SUID/GUID applications the rules
have been further restricted, and where in the past a dynamic string
token sequence may have been interpreted as a literal string it will
now cause a load failure. These load failures were always considered
unspecified behaviour from the perspective of the dynamic loader, and
for safety are now load errors e.g. /foo/${ORIGIN}.so in DT_NEEDED
results in a load failure now.

* The nonstandard header files <libio.h> and <_G_config.h> are no longer
installed. Software that was using either header should be updated to
use standard <stdio.h> interfaces instead.
* The stdio functions 'getc' and 'putc' are no longer defined as macros.
This was never required by the C standard, and the macros just expanded
to call alternative names for the same functions. If you hoped getc and
putc would provide performance improvements over fgetc and fputc, instead
investigate using (f)getc_unlocked and (f)putc_unlocked, and, if
necessary, flockfile and funlockfile.
* All stdio functions now treat end-of-file as a sticky condition. If you
read from a file until EOF, and then the file is enlarged by another
process, you must call clearerr or another function with the same effect
(e.g. fseek, rewind) before you can read the additional data. This
corrects a longstanding C99 conformance bug. It is most likely to affect
programs that use stdio to read interactive input from a terminal.
(Bug #1190.)
* The macros 'major', 'minor', and 'makedev' are now only available from
the header <sys/sysmacros.h>; not from <sys/types.h> or various other
headers that happen to include <sys/types.h>. These macros are rarely
used, not part of POSIX nor XSI, and their names frequently collide with
user code; see https://sourceware.org/bugzilla/show_bug.cgi?id=19239 for
further explanation.
<sys/sysmacros.h> is a GNU extension. Portable programs that require
these macros should first include <sys/types.h>, and then include
<sys/sysmacros.h> if __GNU_LIBRARY__ is defined.
[BZ #19239] Don't include sys/sysmacros.h from sys/types.h. This completes the deprecation and removal of this inclusion, which was begun in the 2.25 release. * posix/sys/types.h: Don't include sys/sysmacros.h. * misc/sys/sysmacros.h: Remove the conditional deprecation warnings for the macros defined by this header.

Remove tilegx port. Since tile support has been removed from the Linux kernel for 4.17, this patch removes the (unmaintained) port to tilegx from glibc (the tilepro support having been previously removed). This reflects the general principle that a glibc port needs upstream support for the architecture in all the components it build-depends on (so binutils, GCC and the Linux kernel, for the normal case of a port supporting the Linux kernel but no other OS), in order to be maintainable. Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile, there are updates to various comments referencing tile for which removal of those references seemed appropriate. The configuration is removed from README and from build-many-glibcs.py. contrib.texi keeps mention of removed contributions, but I updated Chris Metcalf's entry to reflect that he also contributed the non-removed support for the generic Linux kernel syscall interface. __ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used by tile. * sysdeps/tile: Remove. * sysdeps/unix/sysv/linux/tile: Likewise. * README (tilegx-*-linux-gnu): Remove from list of supported configurations. * manual/contrib.texi (Contributors): Mention Chris Metcalf's contribution of support for generic Linux kernel syscall interface. * scripts/build-many-glibcs.py (Context.add_all_configs): Remove tilegx configurations.

Obsolete nfsservctl. The Linux nfsservctl syscall was removed in Linux 3.1.

Make llseek a compat symbol (bug 18471). The llseek function name is an obsolete, Linux-specific, unprototyped name for lseek64 with a link-time warning. This patch completes the obsoletion of this function name by making it into a compat symbol, not available for newly linked programs and not included in the ABI for new ports. When a compat symbol is defined in syscalls.list, the code for that function is not built at all for static linking unless some non-compat symbol for that function is also defined with an explicit symbol version, so an explicit symbol version for lseek64 is added to the MIPS n32 syscalls.list. The case in make-syscalls.sh that handles such explicit non-compat symbol versions then needs to be changed to use weak_alias instead of strong_alias when the syscall is built outside of libc, to avoid linknamespace failures from a strong lseek64 symbol in static libpthread. The x32 llseek.S was as far as I could tell already unused (nothing builds an llseek.* source file, at least since the lseek / lseek64 / llseek consolidation), so is removed in this patch as well. Tested for x86_64 and x86, and with build-many-glibcs.py.

Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251) This patch fixes the OFD ("file private") locks for architectures that support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and F_{SET,GET}L{W}K64 expects a flock64 argument and when using old F_OFD_* flags with a non LFS flock argument the kernel might interpret the underlying data wrongly. Kernel idea originally was to avoid using such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS semantic as default it is possible to provide the functionality and avoid the bogus struct kernel passing by adjusting the struct manually for the required flags. The idea follows other LFS interfaces that provide two symbols: 1. A new LFS fcntl64 is added on default ABI with the usual macros to select it for FILE_OFFSET_BITS=64. 2. The Linux non-LFS fcntl use a stack allocated struct flock64 for F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided struct. 3. Keep a compat symbol with old broken semantic for architectures that do not define __OFF_T_MATCHES_OFF64_T. So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will aliased to fcntl and no adjustment would be required. So to actually use F_OFD_* with LFS support the source must be built with LFS support (_FILE_OFFSET_BITS=64). Also F_OFD_SETLKW command is handled a cancellation point, as for F_SETLKW{64}. Checked on x86_64-linux-gnu and i686-linux-gnu.

* The fcntl function now have a Long File Support variant named fcntl64. It
is added to fix some Linux Open File Description (OFD) locks usage on non
LFS mode. As for others *64 functions, fcntl64 semantics are analogous with
fcntl and LFS support is handled transparently. Also for Linux, the OFD
locks act as a cancellation entrypoint.
Disallow use of DES encryption functions in new programs. The functions encrypt, setkey, encrypt_r, setkey_r, cbc_crypt, ecb_crypt, and des_setparity should not be used in new programs, because they use the DES block cipher, which is unacceptably weak by modern standards. Demote all of them to compatibility symbols, and remove their prototypes from installed headers. cbc_crypt, ecb_crypt, and des_setparity were already compat symbols when glibc was configured with --disable-obsolete-rpc. POSIX requires encrypt and setkey to be available when _XOPEN_CRYPT is defined, so this change also removes the definition of X_OPEN_CRYPT from <unistd.h>. The entire "DES Encryption" section is dropped from the manual, as is the mention of AUTH_DES and FIPS 140-2 in the introduction to crypt.texi. The documentation of 'memfrob' cross-referenced the DES Encryption section, which is replaced by a hyperlink to libgcrypt, and while I was in there I spruced up the actual documentation of 'memfrob' and 'strfry' a little. It's still fairly jokey, because those functions _are_ jokes, but they do also have real use cases, so people trying to use them for real should have all the information they need. DES-based authentication for Sun RPC is also insecure and should be deprecated or even removed, but maybe that can be left as TI-RPC's problem.
2018-06-29 14:53:18 +00:00
* The obsolete functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt,
ecb_crypt, and des_setparity are no longer available to newly linked
binaries, and the headers <rpc/des_crypt.h> and <rpc/rpc_des.h> are no
longer installed. These functions encrypted and decrypted data with the
DES block cipher, which is no longer considered secure. Software that
still uses these functions should switch to a modern cryptography library,
such as libgcrypt.
* Reflecting the removal of the encrypt and setkey functions above, the
macro _XOPEN_CRYPT is no longer defined. As a consequence, the crypt
function is no longer declared unless _DEFAULT_SOURCE or _GNU_SOURCE is
enabled.
* The obsolete function fcrypt is no longer available to newly linked
binaries. It was just another name for the standard function crypt,
and it has not appeared in any header file in many years.
New configure option --disable-crypt. Some Linux distributions are experimenting with a new, separately maintained and hopefully more agile implementation of the crypt API. To facilitate this, add a configure option which disables glibc's embedded libcrypt. When this option is given, libcrypt.* and crypt.h will not be built nor installed.
2018-06-29 14:53:47 +00:00
* We have tentative plans to hand off maintenance of the passphrase-hashing
library, libcrypt, to a separate development project that will, we hope,
keep up better with new passphrase-hashing algorithms. We will continue
to declare 'crypt' in <unistd.h>, and programs that use 'crypt' or
'crypt_r' should not need to change at all; however, distributions will
need to install <crypt.h> and libcrypt from a separate project.
In this release, if the configure option --disable-crypt is used, glibc
will not install <crypt.h> or libcrypt, making room for the separate
project's versions of these files. The plan is to make this the default
behavior in a future release.

Version 2.27
Major new features:
Add --enable-static-pie configure option to build static PIE [BZ #19574] Static PIE extends address space layout randomization to static executables. It provides additional security hardening benefits at the cost of some memory and performance. Dynamic linker, ld.so, is a standalone program which can be loaded at any address. This patch adds a configure option, --enable-static-pie, to embed the part of ld.so in static executable to create static position independent executable (static PIE). A static PIE is similar to static executable, but can be loaded at any address without help from a dynamic linker. When --enable-static-pie is used to configure glibc, libc.a is built as PIE and all static executables, including tests, are built as static PIE. The resulting libc.a can be used together with GCC 8 or above to build static PIE with the compiler option, -static-pie. But GCC 8 isn't required to build glibc with --enable-static-pie. Only GCC with PIE support is needed. When an older GCC is used to build glibc with --enable-static-pie, proper input files are passed to linker to create static executables as static PIE, together with "-z text" to prevent dynamic relocations in read-only segments, which are not allowed in static PIE. The following changes are made for static PIE: 1. Add a new function, _dl_relocate_static_pie, to: a. Get the run-time load address. b. Read the dynamic section. c. Perform dynamic relocations. Dynamic linker also performs these steps. But static PIE doesn't load any shared objects. 2. Call _dl_relocate_static_pie at entrance of LIBC_START_MAIN in libc.a. crt1.o, which is used to create dynamic and non-PIE static executables, is updated to include a dummy _dl_relocate_static_pie. rcrt1.o is added to create static PIE, which will link in the real _dl_relocate_static_pie. grcrt1.o is also added to create static PIE with -pg. GCC 8 has been updated to support rcrt1.o and grcrt1.o for static PIE. Static PIE can work on all architectures which support PIE, provided: 1. Target must support accessing of local functions without dynamic relocations, which is needed in start.S to call __libc_start_main with function addresses of __libc_csu_init, __libc_csu_fini and main. All functions in static PIE are local functions. If PIE start.S can't reach main () defined in a shared object, the code sequence: pass address of local_main to __libc_start_main ... local_main: tail call to main via PLT can be used. 2. start.S is updated to check PIC instead SHARED for PIC code path and avoid dynamic relocation, when PIC is defined and SHARED isn't defined, to support static PIE. 3. All assembly codes are updated check PIC instead SHARED for PIC code path to avoid dynamic relocations in read-only sections. 4. All assembly codes are updated check SHARED instead PIC for static symbol name. 5. elf_machine_load_address in dl-machine.h are updated to support static PIE. 6. __brk works without TLS nor dynamic relocations in read-only section so that it can be used by __libc_setup_tls to initializes TLS in static PIE. NB: When glibc is built with GCC defaulted to PIE, libc.a is compiled with -fPIE, regardless if --enable-static-pie is used to configure glibc. When glibc is configured with --enable-static-pie, libc.a is compiled with -fPIE, regardless whether GCC defaults to PIE or not. The same libc.a can be used to build both static executable and static PIE. There is no need for separate PIE copy of libc.a. On x86-64, the normal static sln: text data bss dec hex filename 625425 8284 5456 639165 9c0bd elf/sln the static PIE sln: text data bss dec hex filename 657626 20636 5392 683654 a6e86 elf/sln The code size is increased by 5% and the binary size is increased by 7%. Linker requirements to build glibc with --enable-static-pie: 1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from static PIE. 2. Linker can create working static PIE. The x86-64 linker needs the fix for https://sourceware.org/bugzilla/show_bug.cgi?id=21782 The i386 linker needs to be able to convert "movl main@GOT(%ebx), %eax" to "leal main@GOTOFF(%ebx), %eax" if main is defined locally. Binutils 2.29 or above are OK for i686 and x86-64. But linker status for other targets need to be verified. 3.

executables are like static executables but can be loaded at any address
Add --enable-static-pie configure option to build static PIE [BZ #19574] Static PIE extends address space layout randomization to static executables. It provides additional security hardening benefits at the cost of some memory and performance. Dynamic linker, ld.so, is a standalone program which can be loaded at any address. This patch adds a configure option, --enable-static-pie, to embed the part of ld.so in static executable to create static position independent executable (static PIE). A static PIE is similar to static executable, but can be loaded at any address without help from a dynamic linker. When --enable-static-pie is used to configure glibc, libc.a is built as PIE and all static executables, including tests, are built as static PIE. The resulting libc.a can be used together with GCC 8 or above to build static PIE with the compiler option, -static-pie. But GCC 8 isn't required to build glibc with --enable-static-pie. Only GCC with PIE support is needed. When an older GCC is used to build glibc with --enable-static-pie, proper input files are passed to linker to create static executables as static PIE, together with "-z text" to prevent dynamic relocations in read-only segments, which are not allowed in static PIE. The following changes are made for static PIE: 1. Add a new function, _dl_relocate_static_pie, to: a. Get the run-time load address. b. Read the dynamic section. c. Perform dynamic relocations. Dynamic linker also performs these steps. But static PIE doesn't load any shared objects. 2. Call _dl_relocate_static_pie at entrance of LIBC_START_MAIN in libc.a. crt1.o, which is used to create dynamic and non-PIE static executables, is updated to include a dummy _dl_relocate_static_pie. rcrt1.o is added to create static PIE, which will link in the real _dl_relocate_static_pie. grcrt1.o is also added to create static PIE with -pg. GCC 8 has been updated to support rcrt1.o and grcrt1.o for static PIE. Static PIE can work on all architectures which support PIE, provided: 1. Target must support accessing of local functions without dynamic relocations, which is needed in start.S to call __libc_start_main with function addresses of __libc_csu_init, __libc_csu_fini and main. All functions in static PIE are local functions. If PIE start.S can't reach main () defined in a shared object, the code sequence: pass address of local_main to __libc_start_main ... local_main: tail call to main via PLT can be used. 2. start.S is updated to check PIC instead SHARED for PIC code path and avoid dynamic relocation, when PIC is defined and SHARED isn't defined, to support static PIE. 3. All assembly codes are updated check PIC instead SHARED for PIC code path to avoid dynamic relocations in read-only sections. 4. All assembly codes are updated check SHARED instead PIC for static symbol name. 5. elf_machine_load_address in dl-machine.h are updated to support static PIE. 6. __brk works without TLS nor dynamic relocations in read-only section so that it can be used by __libc_setup_tls to initializes TLS in static PIE. NB: When glibc is built with GCC defaulted to PIE, libc.a is compiled with -fPIE, regardless if --enable-static-pie is used to configure glibc. When glibc is configured with --enable-static-pie, libc.a is compiled with -fPIE, regardless whether GCC defaults to PIE or not. The same libc.a can be used to build both static executable and static PIE. There is no need for separate PIE copy of libc.a. On x86-64, the normal static sln: text data bss dec hex filename 625425 8284 5456 639165 9c0bd elf/sln the static PIE sln: text data bss dec hex filename 657626 20636 5392 683654 a6e86 elf/sln The code size is increased by 5% and the binary size is increased by 7%. Linker requirements to build glibc with --enable-static-pie: 1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from static PIE. 2. Linker can create working static PIE. The x86-64 linker needs the fix for https://sourceware.org/bugzilla/show_bug.cgi?id=21782 The i386 linker needs to be able to convert "movl main@GOT(%ebx), %eax" to "leal main@GOTOFF(%ebx), %eax" if main is defined locally. Binutils 2.29 or above are OK for i686 and x86-64. But linker status for other targets need to be verified. 3. Linker should resolve undefined weak symbols to 0 in static PIE: https://sourceware.org/bugzilla/show_bug.cgi?id=22269 4.

Linker requirements to build glibc with --enable-static-pie: 1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from static PIE. 2. Linker can create working static PIE. The x86-64 linker needs the fix for https://sourceware.org/bugzilla/show_bug.cgi?id=21782 The i386 linker needs to be able to convert "movl main@GOT(%ebx), %eax" to "leal main@GOTOFF(%ebx), %eax" if main is defined locally. Binutils 2.29 or above are OK for i686 and x86-64. But linker status for other targets need to be verified. 3. Linker should resolve undefined weak symbols to 0 in static PIE: https://sourceware.org/bugzilla/show_bug.cgi?id=22269 4. Many ELF backend linkers incorrectly check bfd_link_pic for TLS relocations, which should check bfd_link_executable instead: https://sourceware.org/bugzilla/show_bug.cgi?id=22263 Tested on aarch64, i686 and x86-64.

Optimized generic expf and exp2f with wrappers Based on new expf and exp2f code from https://github.com/ARM-software/optimized-routines/ with wrapper on aarch64: expf reciprocal-throughput: 2.3x faster expf latency: 1.7x faster without wrapper on aarch64: expf reciprocal-throughput: 3.3x faster expf latency: 1.7x faster without wrapper on aarch64: exp2f reciprocal-throughput: 2.8x faster exp2f latency: 1.3x faster libm.so size on aarch64: .text size: -152 bytes .rodata size: -1740 bytes expf/exp2f worst case nearest rounding error: 0.502 ulp worst case non-nearest rounding error: 1 ulp Error checks are inline and errno setting is in separate tail called functions, but the wrappers are kept in this patch to handle the _LIB_VERSION==_SVID_ case. (So e.g. errno is set twice for expf calls and once for __expf_finite calls on targets where the new code is used.) Double precision arithmetics is used which is expected to be faster on most targets (including soft-float) than using single precision and it is easier to get good precision result with it. Const data is kept in a separate translation unit which complicates maintenance a bit, but is expected to give good code for literal loads on most targets and allows sharing data across expf, exp2f and powf. (This data is disabled on i386, m68k and ia64 which have their own expf, exp2f and powf code.) Some details may need target specific tweaks: - best convert and round to int operation in the arg reduction may be different across targets. - code was optimized on fma target, optimal polynomial eval may be different without fma. - gcc does not always generate good code for fp bit representation access via unions or it may be inherently slow on some targets. The libm-test-ulps will need adjustment because.. - The argument reduction ideally uses nearest rounded rint, but that is not efficient on most targets, so the polynomial can get evaluated on a wider interval in non-nearest rounding mode making 1 ulp errors common in that case. - The polynomial is evaluated such that it may have 1 ulp error on negative tiny inputs with upward rounding. * math/Makefile (type-float-routines): Add math_errf and e_exp2f_data. * sysdeps/aarch64/fpu/math_private.h (TOINT_INTRINSICS): Define.

malloc: Abort on heap corruption, without a backtrace [BZ #21754] The stack trace printing caused deadlocks and has been itself been targeted by code execution exploits.
2017-08-30 14:39:41 +00:00
* In order to support faster and safer process termination the malloc API
family of functions will no longer print a failure address and stack
backtrace after detecting heap corruption. The goal is to minimize the
amount of work done after corruption is detected and to avoid potential
security issues in continued process execution. Reducing shutdown time
leads to lower overall process restart latency, so there is benefit both
from a security and performance perspective.
abort: Do not flush stdio streams [BZ #15436]
2017-10-05 12:48:16 +00:00

in deadlocks and further data corruption. This change also affects
process aborts as the result of assertion failures.
Add _Float128 function aliases. This patch adds support for *f128 function aliases on platforms where long double has the binary128 format (and thus GCC 7 provides the _Float128 type with the same ABI as long double but as a distinct type in terms of C type compatibility). This is the same API as provided in glibc 2.26 for powerpc64le / x86_64 / x86 / ia64 where _Float128 has a different format from long double, with the bulk of the API coming from TS 18661-3. All the functions alias the corresponding long double functions, and __* function names are not provided since those are only needed once for each floating-point format, not more than once for different types with the same format (so for example, -ffinite-math-only maps foof128 to __fool_finite, while type-generic macros end up calling e.g. __issignalingl for _Float128 arguments on such platforms). The preparation for this feature was done in previous patches, so this one just needs to add the relevant makefile and header definitions, and update macro definitions of libm_alias_ldouble_other_r, to turn on the feature, and update documentation and ABI baselines.

this format is supported but is not the format of long double.
Add _Float64x function aliases. This patch continues filling out TS 18661-3 support by adding *f64x function aliases on platforms with _Float64x support. (It so happens the set of such platforms is exactly the same as the set of platforms with _Float128 support, although on x86_64, x86 and ia32 the _Float64x format is Intel extended rather than binary128.) The API provided corresponds exactly to that provided for _Float128, mostly coming from TS 18661-3. As these functions always alias those for another type (long double, _Float128 or both), __* function names are not provided, as in other cases of alias types. Given the preparation done in previous patches, this one just enables the feature via Makeconfig and bits/floatn.h, adds symbol versions, and updates documentation and ABI baselines. The symbol versions are present unconditionally as GLIBC_2.27 in the relevant Versions files, as it's OK for those to specify versions for functions that may not be present in some configurations; no additional complexity is needed unless in future some configuration gains support for this type that didn't have such support in 2.27. The Makeconfig additions for ia64 and x86 aren't strictly needed, as those configurations also get float64x-alias-fcts definitions from sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given that _Float64x is not _Float128 for those configurations. A libm-test-ulps update for x86 is included. This is because bits/mathinline.h does not have _Float64x support added and for two functions the use of out-of-line functions results in increased ulps (ifloat64x shares ulps with ildouble / ifloat128 as appropriate). Given that we'd like generally to eliminate bits/mathinline.h optimizations, preferring to have such optimizations in GCC instead, it seems reasonable not to add such support there for new types. GCC support for _FloatN / _FloatNx built-in functions is limited, but has been improved in GCC 8, and at some point I hope the full set of libm built-in functions in GCC, and other optimizations with per-floating-type aspects, will be enabled for all _FloatN / _FloatNx types.

Add _Float64x function aliases. This patch continues filling out TS 18661-3 support by adding *f64x function aliases on platforms with _Float64x support. (It so happens the set of such platforms is exactly the same as the set of platforms with _Float128 support, although on x86_64, x86 and ia32 the _Float64x format is Intel extended rather than binary128.) The API provided corresponds exactly to that provided for _Float128, mostly coming from TS 18661-3. As these functions always alias those for another type (long double, _Float128 or both), __* function names are not provided, as in other cases of alias types. Given the preparation done in previous patches, this one just enables the feature via Makeconfig and bits/floatn.h, adds symbol versions, and updates documentation and ABI baselines. The symbol versions are present unconditionally as GLIBC_2.27 in the relevant Versions files, as it's OK for those to specify versions for functions that may not be present in some configurations; no additional complexity is needed unless in future some configuration gains support for this type that didn't have such support in 2.27.

The patch enables the feature in bits/floatn-common.h, adds symbol versions and documentation with updates to ABI baselines, and arranges for the libm functions for the new types to be tested. As with the _Float64x changes there are some x86 ulps updates because of header inlines not used for the new types (and one other change to the non-multiarch libm-test-ulps, which I suppose comes from using a different compiler version / configuration from when it was last regenerated).

However, it is also the recommended way to create alias mappings, which is why it has more general use. No emulation is provided.

Linux: Implement interfaces for memory protection keys This adds system call wrappers for pkey_alloc, pkey_free, pkey_mprotect, and x86-64 implementations of pkey_get and pkey_set, which abstract over the PKRU CPU register and hide the actual number of memory protection keys supported by the CPU. pkey_mprotect with a -1 key is implemented using mprotect, so it will work even if the kernel does not support the pkey_mprotect system call. The system call wrapers use unsigned int instead of unsigned long for parameters, so that no special treatment for x32 is needed. The flags argument is currently unused, and the access rights bit mask is limited to two bits by the current PKRU register layout anyway.

For memset/bzero, performance comparison with niagara4 code: For memset nonzero data, 256-1023 bytes - 60-90% gain (in cache); 5% gain (out of cache) 1K+ bytes - 80-260% gain (in cache); 40-80% gain (out of cache) For memset zero data (and bzero), 256-1023 bytes - 80-120% gain (in cache), 0% gain (out of cache) 1024+ bytes - 2-4x gain (in cache), 10-35% gain (out of cache) Tested in sparcv9-*-* and sparc64-*-* targets in both multi and non-multi arch configurations.

ldconfig: set LC_COLLATE to C [BZ #22505] ldconfig supports `include' directives and use the glob function to process them. The glob function sort entries according to the LC_COLLATE category. When using a standard "include /etc/ld.so.conf.d/*.conf" entry in /etc/ld.so.conf, the order therefore depends on the locale used to run ldconfig. A few examples of locale specific order that might be disturbing in that context compared to the C locale: - The cs_CZ and sk_SK locales sort the digits after the letters. - The et_EE locale sorts the 'z' between 's' and 't'. This patch fixes that by setting LC_COLLATE to C in order to process files in deterministic order, independently of the locale used to launch ldconfig. NOTE: This should NOT be backported to older release branches. Changelog: [BZ #22505] * elf/ldconfig.c (main): Call setlocale to force LC_COLLATE to C.
2017-12-16 11:25:41 +00:00
* The ldconfig utility now processes `include' directives using the C/POSIX
collation ordering. Previous glibc versions used locale-specific
ordering, the change might break systems that relied on that.

* Support for two grammatical forms of month names has been added.
In a call to strftime, the "%B" and "%b" format specifiers will now
produce the grammatical form required when the month is used as part
of a complete date. New "%OB" and "%Ob" specifiers produce the form
required when the month is named by itself. For instance, in Greek
and in many Slavic and Baltic languages, "%B" will produce the month
in genitive case, and "%OB" will produce the month in nominative case.
In a call to strptime, "%B", "%b", "%h", "%OB", "%Ob", and "%Oh"
are all valid and will all accept any known form of month
name---standalone or complete, abbreviated or full. In a call to
nl_langinfo, the query constants MON_1..12 and ABMON_1..12 return
the strings used by "%B" and "%b", respectively. New query
constants ALTMON_1..12 and _NL_ABALTMON_1..12 return the strings
used by "%OB" and "%Ob", respectively.
In a locale definition file, use "alt_mon" and "ab_alt_mon" to
define the strings for %OB and %Ob, respectively; these have the

Obsolete matherr, _LIB_VERSION, libieee.a. This patch obsoletes support for SVID libm error handling (the system where a user-defined function matherr is called on a libm function error; only enabled if you also set _LIB_VERSION = _SVID_ or _LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global variable to control libm error handling. matherr and _LIB_VERSION are made into compat symbols, not supported for new ports or for static linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_, so disabling errno setting for some functions) is also removed, and all the related definitions are removed from math.h. The manual already recommends against using matherr, and it's already not supported for _Float128 functions (those use new wrappers that don't support matherr, only errno) - this patch means that it becomes possible to e.g. add sinf32 as an alias to sinf without that resulting in undesired matherr support in sinf32 for existing glibc ports. matherr support is not part of any standard supported by glibc (it was removed in XPG4). Because matherr is a function to be defined by the user, of course user programs defining such a function will still continue to link; it just quietly won't be used. If they try to write to the library's copy of _LIB_VERSION to enable SVID error handling, however, they will get a link error (but if they define their own _LIB_VERSION variable, they won't). I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

Obsolete pow10 functions. This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates.

Fix mcontext_t sigcontext namespace (bug 21457). This patch completes the ucontext.h namespace fixes by fixing issues related to the use of struct sigcontext as mcontext_t, and inclusion of <bits/sigcontext.h> even when struct sigcontext is not so used. Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the way to get the sigcontext structure is by including <signal.h> (in a context where __USE_MISC is defined); the sysdeps/generic version of sys/ucontext.h keeps the inclusion by necessity, with a comment about how this is not namespace-clean, but the only configuration that used it, MicroBlaze, gets its own version of the header in this patch. Where mcontext_t was typedefed to struct sigcontext, the contents of struct sigcontext are inserted (with appropriate namespace handling to prefix fields with __ when __USE_MISC is not defined); review should check that this has been done correctly in each case, whether the definition of struct sigcontext comes from glibc headers or from the Linux kernel. This changes C++ name mangling on affected architectures (which do not include x86_64/x86).

Remove add-ons mechanism. glibc has an add-ons mechanism to allow additional software to be integrated into the glibc build. Such add-ons may be within the glibc source tree, or outside it at a path passed to the --enable-add-ons configure option. localedata and crypt were once add-ons, distributed in separate release tarballs, but long since stopped using that mechanism. Linuxthreads was always an add-on. Ports spent some time as an add-on with separate release tarballs, then was first moved into the glibc source tree, then had its sysdeps files moved into the main sysdeps hierarchy so the add-ons mechanism was no longer used. NPTL spent some time as an add-on in the main glibc tree before stopping using the add-on mechanism. libidn used to have separate release tarballs but no longer does so, but still uses the add-ons mechanism within the glibc source tree. Various other software has supported building with the add-ons mechanism at times in the past, but I don't think any is still widely used. Add-ons involve significant, little-used complexity in the glibc build system, and make it hard to understand what the space of possible glibc configurations is. This patch removes the add-ons mechanism. libidn is now built via the Subdirs mechanism to cause any configuration using sysdeps/unix/inet to build libidn; HAVE_LIBIDN (which effectively means shared libraries are available) is now defined via sysdeps/unix/inet/configure. Various references to add-ons around the source tree are removed (in the case of maint.texi, the example list of sysdeps directories is still very out of date). Externally maintained ports should now put their files in the normal sysdeps directory structure rather than being arranged as add-ons; they probably need to change e.g. elf.h anyway, rather than actually being able to work just as a drop-in subtree. Hurd libpthread should be arranged similarly to NPTL, so some files might go in a hurd-pthreads (or similar) top-level directory in glibc, while sysdeps files should go in the normal sysdeps directory structure (possibly in hurd or hurd-pthreads subdirectories, just as there are nptl subdirectories in the sysdeps tree).

Remove --with-fp / --without-fp. There is a configure option --without-fp that specifies that nofpu sysdeps directories should be used instead of fpu directories. For most glibc configurations, this option is of no use: either there is no valid nofpu variant of that configuration, or there are no fpu or nofpu sysdeps directories for that processor and so the option does nothing. For a few configurations, if you are using a soft-float compiler this option is required, and failing to use it generally results in compilation errors from inline asm using unavailable floating-point instructions. We're moving away from --with-cpu to configuring glibc based on how the compiler generates code, and it is natural to do so for --without-fp as well; in most cases the soft-float and hard-float ABIs are incompatible so you have no hope of building a working glibc with an inappropriately configured compiler or libgcc. This patch eliminates --without-fp, replacing it entirely by automatic configuration based on the compiler. Configurations for which this is relevant (coldfire / mips / powerpc32 / sh) define a variable with_fp_cond in their preconfigure fragments (under the same conditions under which those fragments do anything); this is a preprocessor conditional which the toplevel configure script then uses in a test to determine which sysdeps directories to use. The config.make with-fp variable remains. It's used only by powerpc (sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various flags variables. For powerpc, -mcpu= options can imply use of soft-float. That could be an issue if you want to build for e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp sysdeps directory. If in future we eliminate --with-cpu and replace it entirely by testing the compiler, it would be natural at that point to eliminate that code as well (as the user should then just use a compiler defaulting to 476fp and the 476 sysdeps directory would be used automatically). Tested for x86_64, and tested with build-many-glibcs.py that installed shared libraries are unchanged by this patch. * configure.ac (--with-fp): Remove configure option. (with_fp_cond): New variable. (libc_cv_with_fp): New configure test. Use this variable instead of with_fp. * configure: Regenerated. * config.make.in (with-fp): Use @libc_cv_with_fp@. * manual/install.texi (Configuring and compiling): Remove --without-fp. * INSTALL: Regenerated. * sysdeps/m68k/preconfigure (with_fp_cond): Define for ColdFire. * sysdeps/mips/preconfigure (with_fp_cond): Define. * sysdeps/powerpc/preconfigure (with_fp_cond): Define for 32-bit. * sysdeps/sh/preconfigure (with_fp_cond): Define. * scripts/build-many-glibcs.py (Context.add_all_configs): Do not use --without-fp to configure glibc.
2017-12-12 13:56:47 +00:00
* The --without-fp configure option is now ignored. Whether hardware
floating-point instructions are used is now configured based on whether
the compiler used at configure time (without any options implied by a
--with-cpu= configure option) uses such instructions.

Obsolete p_secstodate. This patch, relative to a tree with <https://sourceware.org/ml/libc-alpha/2017-11/msg00797.html> (pending review) applied, obsoletes p_secstodate, making the underlying function __p_secstodate into a compat symbol not available for new binaries or ports.

Deprecate external use of libio.h and _G_config.h. libio.h was originally the header for a set of supported GNU extensions, but they have not been maintained as such in many years, they are now standing in the way of improvements to stdio, and we don't think there are any remaining external users. _G_config.h was never intended for public use, but predates the bits convention. Move both of these headers into the bits directory and provide stubs at top level which issue deprecation warnings.

Changes to build and runtime requirements:
plural.c: improve reproducibility There is a subtle non-determinism when building glibc. This depends on whether the glibc is built using the distibuted file intl/plural.c or built using the generated file intl/plural.c. These two files (intl/plural.c generated vs. distributed) are slightly different, hence we may end up with slightly different libraries. Originally, having "bison" installed was optional. So if "bison" was not present, we always built libraries with the distributed plural.c. If bison was installed, we *** may have *** replaced the distributed file plural.c with a new plural.c generated from plural.y. if the timestamps triggered this rule: plural.c plural.y $(BISON) $(BISONFLAGS) $@ $^ Given that timestamps are not preserved in GIT repositories, the above rule is not reliable without explicitly touching plural.c or plural.y. In other words, the rule may or may not have fired. In summary: there are two distinct sources of non-determinism: 1. Having "bison" installed or not 2. Having "bison" installed but timestamps poorly defined. This patch fixes this by requiring "bison" being installed and by always generating intl/plural.c from intl/plural.y. (This is achieved by simply removing checked-in intl/plural.c) [BZ #22432] * configure.ac (BISON): Require to be present. * configure: Regenerated. * intl/Makefile (generated): Add plural.c. [$(BISON) != no]: Make code unconditional. (plural.c): Change rule to $(objpfx)plural.c. ($(objpfx)plural.o): Depend on $(objpfx)plural.c. * intl/plural.c: Remove. * manual/install.texi (Tools for Compilation): Document bison as required. * INSTALL: Regenerated.

* bison version 2.7 or later is required to generate code in the 'intl'

2017-10-22 07:29:52 +00:00
CVE-2017-15671: The glob function, when invoked with GLOB_TILDE,
would sometimes fail to free memory allocated during ~ operator
processing, leading to a memory leak and, potentially, to a denial
of service.
Update NEWS to add CVE-2017-15804 entry
2017-12-01 20:53:51 +00:00
CVE-2017-15804: The glob function, when invoked with GLOB_TILDE and
without GLOB_NOESCAPE, could write past the end of a buffer while
glob: Fix buffer overflow during GLOB_TILDE unescaping [BZ #22332]
2017-10-22 08:00:57 +00:00
unescaping user names. Reported by Tim Rühsen.
Add references to CVE-2017-17426
2017-12-06 06:39:25 +00:00
CVE-2017-17426: The malloc function, when called with an object size near
the value SIZE_MAX, would return a pointer to a buffer which is too small,
instead of NULL. This was a regression introduced with the new malloc
thread cache in glibc 2.26. Reported by Iain Buclaw.
elf: Compute correct array size in _dl_init_paths [BZ #22606]
2017-12-14 14:18:38 +00:00
CVE-2017-1000408: Incorrect array size computation in _dl_init_paths leads
to the allocation of too much memory. (This is not a security bug per se,
it is mentioned here only because of the CVE assignment.) Reported by
Qualys.
elf: Count components of the expanded path in _dl_init_path [BZ #22607]
2017-12-14 14:05:57 +00:00
CVE-2017-1000409: Buffer overflow in _dl_init_paths due to miscomputation
of the number of search path components. (This is not a security
vulnerability per se because no trust boundary is crossed if the fix for
CVE-2017-1000366 has been applied, but it is mentioned here only because
of the CVE assignment.) Reported by Qualys.
elf: Check for empty tokens before dynamic string token expansion [BZ #22625] The fillin_rpath function in elf/dl-load.c loops over each RPATH or RUNPATH tokens and interprets empty tokens as the current directory ("./"). In practice the check for empty token is done *after* the dynamic string token expansion. The expansion process can return an empty string for the $ORIGIN token if __libc_enable_secure is set or if the path of the binary can not be determined (/proc not mounted). Fix that by moving the check for empty tokens before the dynamic string token expansion. In addition, check for NULL pointer or empty strings return by expand_dynamic_string_token. The above changes highlighted a bug in decompose_rpath, an empty array is represented by the first element being NULL at the fillin_rpath level, but by using a -1 pointer in decompose_rpath and other functions. Changelog: [BZ #22625] * elf/dl-load.c (fillin_rpath): Check for empty tokens before dynamic string token expansion. Check for NULL pointer or empty string possibly returned by expand_dynamic_string_token. (decompose_rpath): Check for empty path after dynamic string token expansion.
2017-12-30 09:54:23 +00:00
CVE-2017-16997: Incorrect handling of RPATH or RUNPATH containing $ORIGIN
for AT_SECURE or SUID binaries could be used to load libraries from the
current directory.
linux: make getcwd(3) fail if it cannot obtain an absolute path [BZ #22679] Currently getcwd(3) can succeed without returning an absolute path because the underlying getcwd syscall, starting with linux commit v2.6.36-rc1~96^2~2, may succeed without returning an absolute path. This is a conformance issue because "The getcwd() function shall place an absolute pathname of the current working directory in the array pointed to by buf, and return buf". This is also a security issue because a non-absolute path returned by getcwd(3) causes a buffer underflow in realpath(3). Fix this by checking the path returned by getcwd syscall and falling back to generic_getcwd if the path is not absolute, effectively making getcwd(3) fail with ENOENT. The error code is chosen for consistency with the case when the current directory is unlinked. [BZ #22679] CVE-2018-1000001 * sysdeps/unix/sysv/linux/getcwd.c (__getcwd): Fall back to generic_getcwd if the path returned by getcwd syscall is not absolute. * io/tst-getcwd-abspath.c: New test. * io/Makefile (tests): Add tst-getcwd-abspath.
2018-01-07 02:03:41 +00:00
CVE-2018-1000001: Buffer underflow in realpath function when getcwd function
succeeds without returning an absolute path due to unexpected behaviour
of the Linux kernel getcwd syscall. Reported by halfdog.
Record CVE-2018-6485 in ChangeLog and NEWS [BZ #22343]
2018-02-01 14:00:44 +00:00
CVE-2018-6485: The posix_memalign and memalign functions, when called with
an object size near the value of SIZE_MAX, would return a pointer to a
buffer which is too small, instead of NULL. Reported by Jakub Wilk.
Record CVE-2018-6551 in NEWS and ChangeLog [BZ #22774]
2018-02-06 08:19:03 +00:00
CVE-2018-6551: The malloc function, when called with an object size near

2017-07-06 17:37:30 +00:00
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.

- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload” (RES_NORELOAD) disables this behavior.
[BZ 21340] add support for POSIX_SPAWN_SETSID This patch adds support for the POSIX_SPAWN_SETSID flag.

- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search” directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
Require Linux kernel 3.2 or later on x86 / x86_64. As per the recent discussion, this patch implements a requirement for Linux 3.2 or later for x86 and x86_64. This is only the initial change to increase the configured minimum; it's expected that followup patches would deal with associated removal of conditionals that are no longer needed. If we remove the start-up test on the kernel version, of course the NEWS and README text should then be revised (to reflect that this version is just one such that glibc does not intend to include compatibility code for any older kernel version, rather than older kernels necessarily failing to work or glibc necessarily having compatibility code for newer interfaces). The followups would be able to assume presence of getcpu (x86_64), recvmmsg (not always through its own syscall, sometimes only through socketcall), sendmmsg (likewise), /proc/$pid/task/$tid/comm, f_flags from statfs, prlimit64. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/i386/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/i386/configure: Regenerated. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/x86_64/64/configure: Regenerated. * README: Update statement about Linux kernel requirements.

* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
Rename xlocale.h to bits/types/__locale_t.h. xlocale.h is already a single-type micro-header, defining struct __locale_struct and the typedefs __locale_t and locale_t. This patch brings it into the bits/types/ scheme: there are now bits/types/__locale_t.h which defines only __locale_struct and __locale_t, and bits/types/locale_t.h which defines locale_t as well as the other two. None of *our* headers need __locale_t.h, but it appears to me that libstdc++ could make use of it. There are a lot of external uses of xlocale.h, but all the uses I checked had an autoconf test or equivalent for its existence. It has never been available from other C libraries, and it has always contained a comment reading "This file is not standardized, don't rely on it, it can go away without warning" so I think dropping it is pretty safe. I also took the opportunity to clean up comments in various public header files that still talk about the *_l interfaces as though they were completely nonstandard. There are a few of them, notably the strtoX_l and wcstoX_l families, that haven't been standardized, but the bulk are in POSIX.1-2008. * locale/xlocale.h: Rename to... * locale/bits/types/__locale_t.h: ...here. Adjust commentary. Only define struct __locale_struct and __locale_t, not locale_t. * locale/bits/types/locale_t.h: New file; define locale_t here. * locale/Makefile (headers): Update to match. * include/xlocale.h: Delete wrapper. * include/bits/types/__locale_t.h: New wrapper. * include/bits/types/locale_t.h: New wrapper. * ctype/ctype.h, include/printf.h, include/time.h * locale/langinfo.h, locale/locale.h, stdlib/monetary.h * stdlib/stdlib.h, string/string.h, string/strings.h, time/time.h * wcsmbs/wchar.h, wctype/wctype.h: Use bits/types/locale_t.h. Correct outdated comments regarding the standardization status of the functions that take locale_t arguments. * stdlib/strtod_l.c, stdlib/strtof_l.c, stdlib/strtol_l.c * stdlib/strtold_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstold.c, wcsmbs/wcstold_l.c: Don't include xlocale.h. If necessary, include locale.h instead. * stdlib/strtold_l.c: Unconditionally include wchar.h.

* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
Factor out shared definitions from bits/signum.h. Many of the things defined by bits/signum.h are invariant across all supported operating systems. This patch factors out all of them to a new header bits/signum-generic.h, which each bits/signum.h will include and then override whichever things need adjustment. Normally that will mean, at most, adding or changing a few signal numbers. A user-visible side effect is that the obsolete signal constant SIGUNUSED (which is an alias for SIGSYS on all platforms that define it) is no longer exposed by any version of bits/signum.h. A side effect only relevant to glibc hackers is that _NSIG is now defined in terms of __SIGRTMAX, instead of the other way around. This is because __SIGRTMAX varies from platform to platform, but _NSIG==__SIGRTMAX+1 is true universally. If your platform doesn't support realtime signals, leave __SIGRTMAX equal to __SIGRTMIN. I also added a Linux-specific test to make sure that our signal constants match the ones in <asm/signal.h>, since we can't use that header (it's not even vaguely namespace-clean). * bits/signum-generic.h: Renamed from bits/signum.h. Add proper multiple include guard and misuse check. Define __SIGRTMIN = __SIGRTMAX = 32, and define _NSIG = __SIGRTMAX+1. Move definition of SIGIO to "archaic names for compatibility" section. * bits/signum.h: New file which just includes bits/signum-generic.h. * sysdeps/unix/bsd/bits/signum.h * sysdeps/unix/sysv/linux/bits/signum.h * sysdeps/unix/sysv/linux/alpha/bits/signum.h * sysdeps/unix/sysv/linux/hppa/bits/signum.h * sysdeps/unix/sysv/linux/mips/bits/signum.h * sysdeps/unix/sysv/linux/sparc/bits/signum.h Just include <bits/signum-generic.h> and then add or adjust signal constants. Do not define SIGUNUSED, SIGRTMIN, or SIGRTMAX. * signal/Makefile: Install bits/signum-generic.h. * signal/signal.h: Define SIGRTMIN and SIGRTMAX here. * sysdeps/generic/siglist.h: SIGSYS and SIGWINCH are universal. Prefer SIGPOLL to SIGIO. Simplify #ifdeffage. * sysdeps/unix/sysv/linux/tst-signal-numbers.sh: New test. * sysdeps/unix/sysv/linux/Makefile: Run it.

* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
Add reallocarray function The reallocarray function is an extension from OpenBSD. It is an integer-overflow-safe replacement for realloc(p, X*Y) and malloc(X*Y) (realloc(NULL, X*Y)). It can therefore help in preventing certain security issues in code. This is an updated version of a patch originally submitted by Rüdiger Sonderfeld in May 2014 [1]. Checked on i686-linux-gnu and x86_64-linux-gnu.

* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
Optimize generic spinlock code and use C11 like atomic macros. This patch optimizes the generic spinlock code. The type pthread_spinlock_t is a typedef to volatile int on all archs. Passing a volatile pointer to the atomic macros which are not mapped to the C11 atomic builtins can lead to extra stores and loads to stack if such a macro creates a temporary variable by using "__typeof (*(mem)) tmp;". Thus, those macros which are used by spinlock code - atomic_exchange_acquire, atomic_load_relaxed, atomic_compare_exchange_weak - have to be adjusted. According to the comment from Szabolcs Nagy, the type of a cast expression is unqualified (see http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_423.htm): __typeof ((__typeof (*(mem)) *(mem)) tmp; Thus from spinlock perspective the variable tmp is of type int instead of type volatile int. This patch adjusts those macros in include/atomic.h. With this construct GCC >= 5 omits the extra stores and loads. The atomic macros are replaced by the C11 like atomic macros and thus the code is aligned to it. The pthread_spin_unlock implementation is now using release memory order instead of sequentially consistent memory order. The issue with passed volatile int pointers applies to the C11 like atomic macros as well as the ones used before. I've added a glibc_likely hint to the first atomic exchange in pthread_spin_lock in order to return immediately to the caller if the lock is free. Without the hint, there is an additional jump if the lock is free. I've added the atomic_spin_nop macro within the loop of plain reads. The plain reads are also realized by C11 like atomic_load_relaxed macro. The new define ATOMIC_EXCHANGE_USES_CAS determines if the first try to acquire the spinlock in pthread_spin_lock or pthread_spin_trylock is an exchange or a CAS. This is defined in atomic-machine.h for all architectures. The define SPIN_LOCK_READS_BETWEEN_CMPXCHG is now removed. There is no technical reason for throwing in a CAS every now and then, and so far we have no evidence that it can improve performance. If that would be the case, we have to adjust other spin-waiting loops elsewhere, too! Using a CAS loop without plain reads is not a good idea on many targets and wasn't used by one. Thus there is now no option to do so. Architectures are now using the generic spinlock automatically if they do not provide an own implementation. Thus the pthread_spin_lock.c files in sysdeps folder are deleted. ChangeLog: * NEWS: Mention new spinlock implementation. * include/atomic.h: (__atomic_val_bysize): Cast type to omit volatile qualifier. (atomic_exchange_acq): Likewise.

Enable tunables by default All of the major architectures are adopting tunables as a way to add tuning to the library, from hwcap_mask for aarch64 to HLE for s390 and ifunc and cache geometry for x86. Given this adoption and the fact that we don't want additional tuning knobs to be added outside of tunables, it makes sense to enable tunables by default using this trivial patch. Smoke tested on x86 to ensure that tunables code was built without specifying it as a configure flag. I have kept it as --enabled and not changed it to --disable since we want to still keep the option of different kinds of front-ends for tunables. * configure.ac(--enable-tunables): Enable by default. * configure: Regenerate. * NEWS: Mention change. * manual/install.texi (enable-tunables): Adjust documentation. * INSTALL: Regenerate.

128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
powerpc64le: Enable float128 This patch adds ULPs for the float128 type, updates the abilist for libc and libm, and adds the files bits/floatn.h and float128-abi.h, in order to enable the new type for powerpc64le. This patch also adds the implementation of sqrtf128 for powerpc64le, since it is not implemented in libgcc. The sfp-machine.h header is taken from libgcc.

Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been

2017-07-05 13:03:00 +00:00
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
Consistently say "GNU C Library" in NEWS, not "glibc".
2017-07-05 13:46:57 +00:00
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)

2017-07-05 13:03:00 +00:00
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.

2017-07-05 13:03:00 +00:00
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)

resolv: Automatically reload a changed /etc/resolv.conf file [BZ #984] This commit enhances the stub resolver to reload the configuration in the per-thread _res object if the /etc/resolv.conf file has changed. The resolver checks whether the application has modified _res and will not overwrite the _res object in that case. The struct resolv_context mechanism is used to check the configuration file only once per name lookup.

fixed (CVE-2017-12133).

Version 2.25
Support __STDC_WANT_LIB_EXT2__ feature test macro. This patch implements support for the __STDC_WANT_LIB_EXT2__ feature test macro from ISO/IEC TR 24731-2:2010, thereby implementing one possible approach for supporting ISO C feature test macros. Recall that, as described in <https://sourceware.org/ml/libc-alpha/2016-05/msg00486.html>, these macros work based on the definition when affected headers are included, so cannot be handled once when the first system header is included because that might not be one of the headers the particular macro in question affects. <https://sourceware.org/ml/libc-alpha/2016-05/msg00680.html> expresses views on possible approaches for implementation and <https://sourceware.org/ml/libc-alpha/2016-06/msg00039.html> follows up on that. This patch arranges things so that the relevant condition is __GLIBC_USE (LIB_EXT2), following one of the suggestions given. Headers using these macros include <bits/libc-header-start.h>, which in turn includes <features.h>. Headers must define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION before including <bits/libc-header-start.h>, to discourage inclusion outside glibc as requested. __USE_GNU conditions on affected functions are changed to __GLIBC_USE (LIB_EXT2), while it's added as an additional alternative on the conditions for functions already enabled for some POSIX versions. It would be possible to convert existing __USE_* conditionals to __GLIBC_USE (with the relevant __GLIBC_USE_* being defined in <features.h> where __USE_* are presently defined), and so make them typo-proof (given -Wundef -Werror in glibc builds) because __GLIBC_USE is used with #if not #ifdef / #if defined. No attempt is made to enforce the rule about diagnosing different definitions of __STDC_WANT_LIB_EXT2__ when affected headers are included; such a diagnostic is incompatible with multiple-include guards on the affected headers, unless compiler extensions are added to support it. As previously noted, glibc does not implement all features from TR 24731-2:2010: the functions aswprintf vaswprintf getwdelim getwline are not in glibc, although they would be appropriate to add if someone wished to do so. But I think it makes sense to support the feature test macro if *any* of the controlled features are present in glibc. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/libc-header-start.h: New file. * Makefile (headers): Add bits/libc-header-start.h. * include/features.h (__STDC_WANT_LIB_EXT2__): Document. (__GLIBC_USE): New macro. * libio/stdio.h: Define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION and include <bits/libc-header-start.h> instead of including <features.h>. (fmemopen): Declare also if [__GLIBC_USE (LIB_EXT2)]. (open_memstream): Likewise. (vasprintf): Declare if [__GLIBC_USE (LIB_EXT2)], not [__USE_GNU]. (__asprintf): Likewise. (asprintf): Likewise. (__getdelim): Declare also if [__GLIBC_USE (LIB_EXT2)]. (getdelim): Likewise. (getline): Likewise. * string/string.h: Define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION and include <bits/libc-header-start.h> instead of including <features.h>. (strdup): Declare also if [__GLIBC_USE (LIB_EXT2)] (strndup): Likewise. * wcsmbs/wchar.h: Define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION and include <bits/libc-header-start.h> instead of including <features.h>. (open_wmemstream): Declare also if [__GLIBC_USE (LIB_EXT2)]. * manual/creature.texi (__STDC_WANT_LIB_EXT2__): Document macro.
2016-08-02 17:40:35 +00:00
* The feature test macro __STDC_WANT_LIB_EXT2__, from ISO/IEC TR
24731-2:2010, is supported to enable declarations of functions from that
TR. Note that not all functions from that TR are supported by the GNU C
Library.

2016-08-02 03:00:21 +00:00
Support __STDC_WANT_IEC_60559_BFP_EXT__ feature test macro. This patch implements support for the __STDC_WANT_IEC_60559_BFP_EXT__ feature test macro from ISO/IEC 18661-1:2014, following the __GLIBC_USE approach now used for __STDC_WANT_LIB_EXT2__.

* The feature test macro __STDC_WANT_IEC_60559_BFP_EXT__, from ISO/IEC TS
18661-1:2014, is supported to enable declarations of functions and macros
Update NEWS feature test macro description of TS 18661-1 support. The NEWS entry for the feature test macro __STDC_WANT_IEC_60559_BFP_EXT__ describes the state of support for that TS as "most features from that TS are not supported by the GNU C Library". This patch updates it to say "not all features from that TS are supported by the GNU C Library". (The functions not yet supported are the fromfp functions - I'm working on them, but they may not be done before the freeze - and the functions round result to narrower type - which definitely won't be started for 2.25, since they require significant infrastructure work. That's 30 functions, which is less than half the number of functions in the TS, so saying "most" now seems inaccurate.)

* The feature test macro __STDC_WANT_IEC_60559_FUNCS_EXT__, from ISO/IEC TS

Make _REENTRANT and _THREAD_SAFE aliases for _POSIX_C_SOURCE=199506L. For many years, the only effect of these macros has been to make unistd.h declare getlogin_r. _POSIX_C_SOURCE >= 199506L also causes this function to be declared. However, people who don't carefully read all the headers might be confused into thinking they need to define _REENTRANT for any threaded code (as was indeed the case a long time ago). Therefore, remove __USE_REENTRANT, and make _REENTRANT and _THREAD_SAFE into synonyms for _POSIX_C_SOURCE=199506L. This will only affect programs that don't select a higher conformance level some other way. For instance, -std=c89 -D_REENTRANT will see a change in visible declarations, but -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT won't, and -D_REENTRANT all by itself also won't, because _DEFAULT_SOURCE implies _POSIX_C_SOURCE > 199506. * include/features.h: Remove __USE_REENTRANT. Treat _REENTRANT and _THREAD_SAFE the same as _POSIX_C_SOURCE=199506L, if a higher POSIX conformance level has not been selected by other macros. * NEWS, manual/creature.texi: Document this change. * posix/unistd.h, posix/bits/unistd.h: Don't check __USE_REENTRANT. * include/libc-symbols.h: Don't define _REENTRANT. * scripts/check-installed-headers.sh: Don't undefine _REENTRANT.
2016-12-06 15:14:42 +00:00
* The nonstandard feature selection macros _REENTRANT and _THREAD_SAFE are
now treated as compatibility synonyms for _POSIX_C_SOURCE=199506L.
Since the GNU C Library defaults to a much newer revision of POSIX, this
will only affect programs that specifically request an old conformance
mode. For instance, a program compiled with -std=c89 -D_REENTRANT will
see a change in the visible declarations, but a program compiled with
just -D_REENTRANT, or -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT,
will not.
Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
defined by all multithreaded code, but glibc has not required this for
many years.

Add femode_t functions. TS 18661-1 defines a type femode_t to represent the set of dynamic floating-point control modes (such as the rounding mode and trap enablement modes), and functions fegetmode and fesetmode to manipulate those modes (without affecting other state such as the raised exception flags) and a corresponding macro FE_DFL_MODE. This patch series implements those interfaces for glibc. This first patch adds the architecture-independent pieces, the x86 and x86_64 implementations, and the <bits/fenv.h> and ABI baseline updates for all architectures so glibc keeps building and passing the ABI tests on all architectures. Subsequent patches add the fegetmode and fesetmode implementations for other architectures. femode_t is generally an integer type - the same type as fenv_t, or as the single element of fenv_t where fenv_t is a structure containing a single integer (or the single relevant element, where it has elements for both status and control registers) - except where architecture properties or consistency with the fenv_t implementation indicate otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic pointer value (-1 cast to const femode_t *), a value that can be distinguished from valid pointers by its high bits but otherwise contains a representation of the desired register contents, or a pointer to a constant variable (the powerpc case; __fe_dfl_mode is added as an exported constant object, an alias to __fe_dfl_env). Note that where architectures (that share a register between control and status bits) gain definitions of new floating-point control or status bits in future, the implementations of fesetmode for those architectures may need updating (depending on whether the new bits are control or status bits and what the implementation does with previously unknown bits), just like existing implementations of <fenv.h> functions that take care not to touch reserved bits may need updating when the set of reserved bits changes. (As any new bits are outside the scope of ISO C, that's just a quality-of-implementation issue for supporting them, not a conformance issue.) As with fenv_t, femode_t should properly include any software DFP rounding mode (and for both fenv_t and femode_t I'd consider that fragment of DFP support appropriate for inclusion in glibc even in the absence of the rest of libdfp; hardware DFP rounding modes should already be included if the definitions of which bits are status / control bits are correct). Tested for x86_64, x86, mips64 (hard float, and soft float to test the fallback version), arm (hard float) and powerpc (hard float, soft float and e500).

Define FE_SNANS_ALWAYS_SIGNAL. TS 18661-1 defines a macro FE_SNANS_ALWAYS_SIGNAL in <fenv.h>, to indicate that the recommended practice regarding sNaNs (that operations always produce a qNaN output with "invalid" exception, even in the fmax / fmin / hypot / pow cases where a qNaN input would not result in qNaN output) is followed. Now that those functions with C99 special cases for NaNs have been fixed not to apply those special cases to sNaN, only to qNaN, glibc follows that recommended practice. This patch makes it define the corresponding macro. Since compiler optimizations may affect whether sNaNs behave as expected and the macro relates to both language and library features, it is only defined if __SUPPORT_SNAN__ is defined (which GCC defines for -fsignaling-nans). It is also not defined if FE_INVALID is undefined, since the recommended practice specifically refers to raising the "invalid" exception, so it seems inappropriate to define the macro for soft-float cases without support for exceptions. (Further refinement would be possible in cases where bits/fenv.h is shared by configurations both with and without exceptions support.) Tested for x86_64 and x86, and also did compile-only testing for nios2 to cover the no-exceptions case. * math/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT) && FE_INVALID && __SUPPORT_SNAN__] (FE_SNANS_ALWAYS_SIGNAL): New macro. * math/test-fe-snans-always-signal.c: New file. * math/Makefile (tests): Add test-fe-snans-always-signal.

fesetexcept, fetestexceptflag, fegetmode and fesetmode functions, the
femode_t type and the FE_DFL_MODE and FE_SNANS_ALWAYS_SIGNAL macros.
Add fesetexcept. TS 18661-1 defines an fesetexcept function for setting floating-point exception flags without the side-effect of causing enabled traps to be taken. This patch series implements this function for glibc. The present patch adds the fallback stub implementation, x86 and x86_64 implementations, documentation, tests and ABI baseline updates. The remaining patches, some of them untested, add implementations for other architectures. The implementations generally follow those of the fesetexceptflag function. As for fesetexceptflag, the approach taken for architectures where setting flags causes enabled traps to be taken is to set the flags (and potentially cause traps) rather than refusing to set the flags and returning an error. Since ISO C and TS 18661 provide no way to enable traps, this is formally in accordance with the standards. The NEWS entry should be considered a placeholder, since this patch series is intended to be followed by further such series adding other TS 18661-1 features, so that the NEWS entry would end up looking more like * New <fenv.h> features from TS 18661-1:2014 are added to libm: the fesetexcept, fetestexceptflag, fegetmode and fesetmode functions, the femode_t type and the FE_DFL_MODE macro. with hopefully more such entries for other features, rather than having an entry for a single function in the end.

Add <limits.h> integer width macros. TS 18661-1 defines macros for the width of integer types, intended for use with the fromfp functions to convert from floating-point types to integer types of any width, in any rounding mode and with control over whether "inexact" is raised. Such macros are, of course, more generally useful than just with those functions. Those macros are added to <limits.h> and <stdint.h>. This patch adds the <limits.h> macros to glibc's header, with the <stdint.h> ones intended to be added in a separate patch (which would add to the NEWS entry created by this patch).

Add issubnormal. TS 18661-1 adds an issubnormal classification macro to <math.h>. This patch implements it for glibc. There are no new underlying functions in libm because the implementation uses fpclassify; any optimizations for this macro should be done through adding __builtin_subnormal in GCC and using it in the header for suitable GCC versions, not through adding other optimized inline or out-of-line versions to glibc. The intended structure of the NEWS entry for <math.h> features from TS 18661-1 is like: * New <math.h> features are added from TS 18661-1:2014: - Nearest integer functions: roundeven, roundevenf, roundevenl. - Comparison macros: iseqsig. - Classification macros: iscanonical, issubnormal, iszero. (that is, following the grouping of interfaces in TS 18661-1:2014, with any group where any interfaces are new in glibc 2.25 being listed like that).

- Signaling NaN macros: SNANF, SNAN, SNANL.
Add fromfp functions. TS 18661-1 defines fromfp functions (fromfp, fromfpx, ufromfp, ufromfpx, and float and long double variants) to convert from floating-point to an integer type with any signedness and any given width up to that of intmax_t, in any of the five IEEE rounding modes (the usual four for binary floating point, plus rounding to nearest with ties rounding away from zero), with control of whether in-range non-integer values should result in the "inexact" exception being raised. This patch implements these functions for glibc. These implementations are (apart from raising exceptions) pure integer implementations; it's entirely possible optimized versions could be devised for some architectures. A common math/fromfp.h header provides various common helper code that can readily be shared between the implementations for different types. For each type, the bulk of the implementation is also shared between the four functions, with wrappers that define UNSIGNED and INEXACT macros appropriately before including the main implementation. As the functions return intmax_t and uintmax_t without math.h being allowed to expose those typedef names, they are declared using __intmax_t and __uintmax_t as obtained from <bits/types.h>. The FP_INT_* rounding direction macros are defined as ascending integers in the order the names are listed in the TS; I see no significant value in allowing architectures to vary the values of them. The libm-test machinery is duly adapted to handle unsigned int arguments, and intmax_t and uintmax_t results. Because each test input is generally tested for four functions, five rounding modes and several different widths, the libm-test.inc additions are very large. Thus, the diffs in the body of this message exclude the libm-test.inc changes, with the full patch being attached gzipped. The bulk of the new tests were generated (expanded from a test input plus rounding results and information about where it lies in the relevant interval between integers, to libm-test tests for all relevant combinations of function, rounding direction and width) by a script that's included in the patch as math/gen-fromfp-tests.py (input data math/gen-fromfp-tests-inputs); as an ad hoc script that's not really expected to be rerun, it's not very polished, but it's at least plausibly useful for adding any further tests for these functions in future. I may split the libm-test tests up by function in future (so both libm-test.inc and auto-libm-test-out are split into separate files, and the tests for each function are also built and run separately), but not for 2.25. For no obvious reason, adding tgmath tests for the new functions resulted in -Wuninitialized errors from test-tgmath.c about the variable i being used uninitialized. Those errors were correct - the variable is read by the frexp version in test-tgmath.c (where real frexp would write through that pointer instead of reading it) - but I don't know why this patch would result in the pre-existing issue being newly detected. The patch initializes the variable to avoid those errors. With these changes, glibc 2.25 should have all the library features from TS 18661-1 other than the functions that round result to narrower type (and constant rounding directions, but I'm considering those mainly a compiler feature not a library one).

- Nearest integer functions: roundeven, roundevenf, roundevenl, fromfp,
fromfpf, fromfpl, ufromfp, ufromfpf, ufromfpl, fromfpx, fromfpxf,
fromfpxl, ufromfpx, ufromfpxf, ufromfpxl.
Add roundeven, roundevenf, roundevenl. TS 18661-1 defines roundeven functions that round a floating-point number to the nearest integer, in that floating-point type, with ties rounding to even (whereas the round functions round ties away from zero). As with other such functions, they raise no exceptions apart from "invalid" for signaling NaNs. There was a previous user request for this functionality in glibc in <https://sourceware.org/ml/libc-help/2015-02/msg00005.html>. This patch implements these functions for glibc. The implementations use integer bit-manipulation (or roundeven on the high and low parts, in the IBM long double case). It's possible that there may be faster approaches on some architectures (in particular, on AArch64 the frintn instruction should do exactly what's required); I'll leave it to architecture maintainers or others interested to implement such architecture-specific versions if desired. (Where architectures have instructions to round to nearest integer in the current rounding mode, implementations saving and restoring the rounding mode - and dealing with exceptions if those instructions generate "inexact" - are also possible, though their performance depends on the cost of manipulating exceptions / rounding mode state.) Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (roundeven): New declaration. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (roundeven): New macro. * math/Versions (roundeven): New libm symbol at version GLIBC_2.25.

Add llogb, llogbf, llogbl. TS 18661-1 defines llogb functions that are like ilogb except that they return long int instead of int. Corresponding FP_LLOGB* macros are defined, whose values are required to have the obvious correspondence to those of the FP_ILOGB* macros. This patch implements these functions and macros for glibc. llogb uses the type-generic infrastructure, with an implementation similar to the wrapper for ilogb but with additional conversion from FP_ILOGB* to FP_LLOGB*; this approach avoids needing to modify or duplicate any of the architecture-specific ilogb implementations. Tests are also based on those for ilogb. Ideally the llogb functions would alias the ilogb ones when long is 32-bit, but such aliasing requires the associated header declarations of the different-type alias to be hidden, typically by defining macros before including the header (see e.g. how sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to __hidden_lround before including <math.h>). The infrastructure for type-generic function implementations does not support defining such macros at present (since C code can't define a macro whose name is determined by other macros). So this patch leaves them as separate functions (similar to e.g. scalbln and scalbn being separate in such a case as well), but with the remapping of FP_ILOGB* to FP_LLOGB* conditioned out in the case where it would be the identity map.

- Max-min magnitude functions: fmaxmag, fmaxmagf, fmaxmagl, fminmag,
fminmagf, fminmagl.
Add iseqsig. TS 18661-1 adds an iseqsig type-generic comparison macro to <math.h>. This macro is like the == operator except that unordered operands result in the "invalid" exception and errno being set to EDOM. This patch implements this macro for glibc. Given the need to set errno, this is implemented with out-of-line functions __iseqsigf, __iseqsig and __iseqsigl (of which the last only exists at all if long double is ABI-distinct from double, so no function aliases or compat support are needed). The present patch ignores excess precision issues; I intend to deal with those in a followup patch. (Like comparison operators, type-generic comparison macros should *not* convert operands to their semantic types but should preserve excess range and precision, meaning that for some argument types and values of FLT_EVAL_METHOD, an underlying function should be called for a wider type than that of the arguments.) The underlying functions are implemented with the type-generic template machinery. Comparing x <= y && x >= y is sufficient in ISO C to achieve an equality comparison with "invalid" raised for unordered operands (and the results of those two comparisons can also be used to tell whether errno needs to be set). However, some architectures have GCC bugs meaning that unordered comparison instructions are used instead of ordered ones. Thus, a mechanism is provided for architectures to use an explicit call to feraiseexcept to raise exceptions if required. If your architecture has such a bug you should add a fix-fp-int-compare-invalid.h header for it, with a comment pointing to the relevant GCC bug report; if such a GCC bug is fixed, that header's contents should have a __GNUC_PREREQ conditional added so that the workaround can eventually be removed for that architecture.

- Comparison macros: iseqsig.
Add iscanonical. TS 18661-1 adds an iscanonical classification macro to <math.h>. The motivation for this is decimal floating-point, where some values have both canonical and noncanonical encodings. For IEEE binary interchange formats, all encodings are canonical. For x86/m68k ldbl-96, and for ldbl-128ibm, there are encodings that do not represent any valid value of the type; although formally iscanonical does not need to handle trap representations (and so could just always return 1), it seems useful, and in line with the description in the TS of "representations that are extraneous to the floating-point model" as being non-canonical (as well as "redundant representations of some or all of its values"), for it to detect those representations and return 0 for them. This patch adds iscanonical to glibc. It goes in a header <bits/iscanonical.h>, included under appropriate conditions in <math.h>. The default header version just evaluates the argument (converted to its semantic type, though current GCC will probably discard that conversion and any exceptions resulting from it) and returns 1. ldbl-96 and ldbl-128ibm then have versions of the header that call a function __iscanonicall for long double (the sizeof-based tests will of course need updating for float128 support, like other such type-generic macro implementations). The ldbl-96 version of __iscanonicall has appropriate conditionals to reflect the differences in the m68k version of that format (where the high mantissa bit may be either 0 or 1 when the exponent is 0 or 0x7fff). Corresponding tests for those formats are added as well. Other architectures do not have any new functions added because just returning 1 is correct for all their floating-point formats. Tested for x86_64, x86, mips64 (to test the default macro version) and powerpc. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Include <bits/iscanonical.h>. * bits/iscanonical.h: New file. * math/s_iscanonicall.c: Likewise. * math/Versions (__iscanonicall): New libm symbol at version GLIBC_2.25. * math/libm-test.inc (iscanonical_test_data): New array.

Add issubnormal. TS 18661-1 adds an issubnormal classification macro to <math.h>. This patch implements it for glibc. There are no new underlying functions in libm because the implementation uses fpclassify; any optimizations for this macro should be done through adding __builtin_subnormal in GCC and using it in the header for suitable GCC versions, not through adding other optimized inline or out-of-line versions to glibc. The intended structure of the NEWS entry for <math.h> features from TS 18661-1 is like: * New <math.h> features are added from TS 18661-1:2014: - Nearest integer functions: roundeven, roundevenf, roundevenl. - Comparison macros: iseqsig. - Classification macros: iscanonical, issubnormal, iszero.

- Total order functions: totalorder, totalorderf, totalorderl,
totalordermag, totalordermagf, totalordermagl.
Add totalorder, totalorderf, totalorderl. TS 18661-1 defines totalorder functions implementing the totalOrder comparison operation from IEEE 754-2008. This patch implements these functions for glibc, including the type-generic macro in <tgmath.h>. (The totalordermag functions will be added in a separate patch.) The description of the totalOrder operation is complicated. However, for IEEE interchange binary formats and the preferred quiet NaN convention, what that complicated description means is that you interpret the representation as a sign-magnitude integer (with -0 coming before +0) and do a <= comparison on that interpretation. For finite values and infinities the ordering of the sign-magnitude integers is just the same as the ordering of floating-point values, so this extends that to all representations. (Different representations of the same floating-point value - which includes same quantum in the decimal case - must still be considered equal by this operation, but that issue doesn't arise for IEEE interchange binary formats.) So the complications are: * When MIPS quiet NaN conventions are in use, the representation of NaNs needs adjusting before making such an integer comparison. This patch does this adjustment only when both arguments are NaNs, as there's no need for it if only one is a NaN, and as long as both are NaNs you can just flip the relevant bits without any problems from this turning a NaN into an infinity. * For the m68k version of ldbl-96, where the high mantissa bit is "don't care" for infinities and NaNs, representations where it differs must compare the same. Note: although the testcase for this compiles, I have not actually tested on m68k. * For ldbl-128ibm, the low part must be ignored when the high part is NaN, and low parts of +0 and -0 must be considered the same whatever the high part. The new tests in libm-test.inc are the first tests there specifying particular payloads for input NaNs. Separate tests are also added for the ldbl-96 and ldbl-128ibm special cases where there are different representations of the same value that must compare equal (which can't be covered in libm-test.inc as that only specifies values, not representations).

Add canonicalize, canonicalizef, canonicalizel. TS 18661-1 defines canonicalize functions to produce a canonical version of a floating-point representation. This patch implements these functions for glibc. As with the iscanonical macro, these functions are oriented to the decimal floating-point case, where some values have both canonical and noncanonical representations. However, the functions have a return value that says whether they succeeded in storing a canonical result; thus, they can fail for the case of an invalid representation (while still not making any particular choice from among multiple equally canonical valid representations of the same value). Since no floating-point formats in glibc actually have noncanonical valid representations, a type-generic implementation of these functions can be used that expects iscanonical to return 0 only for invalid representations. Now that iscanonical is used within libm.so, libm_hidden_proto / libm_hidden_def are added for __iscanonicall. The definition of these functions is intended to correspond to a convertFormat operation to the same floating-point format. Thus, they convert signaling NaNs to quiet NaNs, raising the "invalid" exception. Such a conversion "should" produce "the canonical version of that signaling NaN made quiet". libm-test.inc is made to check NaN payloads for the output of these functions, a new feature (at some point manipulation functions such as fabs and copysign should have tests added that verify payload preservation for them). As however some architectures may not follow the recommended practice of preserving NaN payloads when converting a signaling NaN to quiet, a new math-tests.h macro SNAN_TESTS_PRESERVE_PAYLOAD is added, and defined to 0 for non-NAN2008 MIPS; any other architectures seeing test failures for lack of payload preservation in this case should also define this macro to 0. (If any cases arise where the sign isn't preserved either, those should have a similar macro added.) The ldbl-96 and ldbl-128ibm tests of iscanonical are renamed and adapted to test canonicalizel as well on the same representations.

- Canonicalize functions: canonicalize, canonicalizef, canonicalizel.
Add setpayload, setpayloadf, setpayloadl. TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayload functions for glibc; these set a number (pointed to by a function argument) to a quiet NaN with the given payload, or to +0 if the given payload is not valid. The implementations are structured to allow the substance of the implementation to be shared with the setpayloadsig functions when those are added. The semantics in the TS are not entirely clear in the case where the payload passed to the function is zero (see discussion on the WG14 reflector last month). This patch implements what seems the most sensible interpretation, that -0 is never valid to give as the payload, but +0 is valid in the case where the kind of NaN being generated has its high mantissa bit set so payload 0 is actually possible in such a NaN.

- NaN functions: getpayload, getpayloadf, getpayloadl, setpayload,
Add setpayloadsig, setpayloadsigf, setpayloadsigl. TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayloadsig functions for glibc; these are like the setpayload functions, but produce a signaling NaN instead of a quiet NaN. The substance of the implementation was included with the setpayload implementation, so the new files here just need to wrap the main files with different defines to build the new functions. Because the functions store a signaling NaN via a pointer and the libm-test macros choose a suitable initial value for the variable in such a case by comparing with the expected value, the relevant macro needs to clear exceptions after FE_INVALID may have been raised by that comparison.

setpayloadf, setpayloadl, setpayloadsig, setpayloadsigf, setpayloadsigl.
Add getpayload, getpayloadf, getpayloadl. TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the getpayload functions for glibc; these extract the NaN payload (from an argument passed as a pointer, for which corresponding libm-test support is added) and return it in the same floating-point type. The return value of these functions is unspecified for non-NaN arguments; the patch does the simplest thing to implement, which is that the functions do not check whether the argument is a NaN and just treat the relevant bits of the representation as a payload regardless. A conversion from integer to floating-point is used to produce the required return value, except in the ldbl-128 case; as 128-bit integers are not supported for all configurations using ldbl-128, the code constructs the required floating-point representation of the return value directly instead. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (getpayload): New declaration. * math/Versions (getpayload): New libm symbol at version GLIBC_2.25.

* The functions strfromd, strfromf, and strfroml, from ISO/IEC TS 18661-1:2014,
are added to libc. They convert a floating-point number into string.
Enable -fstack-protector=* when requested by configure [BZ #7065]
2016-12-26 09:09:10 +00:00
* Most of glibc can now be built with the stack smashing protector enabled.
It is recommended to build glibc with --enable-stack-protector=strong.
Implemented by Nick Alcock (Oracle).
New string function explicit_bzero (from OpenBSD). explicit_bzero(s, n) is the same as memset(s, 0, n), except that the compiler is not allowed to delete a call to explicit_bzero even if the memory pointed to by 's' is dead after the call. Right now, this effect is achieved externally by having explicit_bzero be a function whose semantics are unknown to the compiler, and internally, with a no-op asm statement that clobbers memory. This does mean that small explicit_bzero operations cannot be expanded inline as small memset operations can, but on the other hand, small memset operations do get deleted by the compiler. Hopefully full compiler support for explicit_bzero will happen relatively soon. There are two new tests: test-explicit_bzero.c verifies the visible semantics in the same way as the existing test-bzero.c, and tst-xbzero-opt.c verifies the not-being-optimized-out property. The latter is conceptually based on a test written by Matthew Dempsky for the OpenBSD regression suite. The crypt() implementation has an immediate use for this new feature. We avoid having to add a GLIBC_PRIVATE alias for explicit_bzero by running all of libcrypt's calls through the fortified variant, __explicit_bzero_chk, which is in the impl namespace anyway. Currently I'm not aware of anything in libc proper that needs this, but the glue is all in place if it does become necessary. The legacy DES implementation wasn't bothering to clear its buffers, so I added that, mostly for consistency's sake. * string/explicit_bzero.c: New routine. * string/test-explicit_bzero.c, string/tst-xbzero-opt.c: New tests. * string/Makefile (routines, strop-tests, tests): Add them. * string/test-memset.c: Add ifdeffage for testing explicit_bzero. * string/string.h [__USE_MISC]: Declare explicit_bzero. * debug/explicit_bzero_chk.c: New routine. * debug/Makefile (routines): Add it. * debug/tst-chk1.c: Test fortification of explicit_bzero. * string/bits/string3.h: Fortify explicit_bzero. * manual/string.texi: Document explicit_bzero. * NEWS: Mention addition of explicit_bzero. * crypt/crypt-entry.c (__crypt_r): Clear key-dependent intermediate data before returning, using explicit_bzero. * crypt/md5-crypt.c (__md5_crypt_r): Likewise. * crypt/sha256-crypt.c (__sha256_crypt_r): Likewise. * crypt/sha512-crypt.c (__sha512_crypt_r): Likewise. * include/string.h: Redirect internal uses of explicit_bzero to __explicit_bzero_chk[_internal]. * string/Versions [GLIBC_2.25]: Add explicit_bzero. * debug/Versions [GLIBC_2.25]: Add __explicit_bzero_chk. * sysdeps/arm/nacl/libc.abilist * sysdeps/unix/sysv/linux/aarch64/libc.abilist * sysdeps/unix/sysv/linux/alpha/libc.abilist * sysdeps/unix/sysv/linux/arm/libc.abilist * sysdeps/unix/sysv/linux/hppa/libc.abilist * sysdeps/unix/sysv/linux/i386/libc.abilist * sysdeps/unix/sysv/linux/ia64/libc.abilist * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist * sysdeps/unix/sysv/linux/microblaze/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist * sysdeps/unix/sysv/linux/nios2/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist * sysdeps/unix/sysv/linux/sh/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Add entries for explicit_bzero and __explicit_bzero_chk.

* The function explicit_bzero, from OpenBSD, has been added to libc. It is
intended to be used instead of memset() to erase sensitive data after use;
the compiler will not optimize out calls to explicit_bzero even if they
are "unnecessary" (in the sense that no _correct_ program can observe the
effects of the memory clear).
Fix default float_t definition (bug 20855). The default (top-level) version of bits/mathdef.h defines float_t to double. It is used on ColdFire, MicroBlaze, Nios II and SH3, all of which define FLT_EVAL_METHOD to 0, so float_t should be float (and C11 requires a certain correspondence between these typedefs and FLT_EVAL_METHOD values). I proposed fixing this default in <https://sourceware.org/ml/libc-alpha/2015-01/msg00499.html>, with no objections from architecture maintainers, and this patch makes that fix. As noted in the NEWS entry added, this might affect the ABIs of non-glibc libraries (ImageMagick has been mentioned in gcc-patches discussion of the S/390 case - which is unaffected by this patch), but as noted in my previous message, affected libraries would have problems with -mfpmath=sse anyway on 32-bit x86. A (compilation) testcase is added to verify the required correspondence of typedefs to FLT_EVAL_METHOD values. This test is built with -fexcess-precision=standard to avoid any issues with GCC 7 on S/390 providing a more accurate FLT_EVAL_METHOD definition in the default (no excess precision) mode. (This will also be usable to test a fix for the recently reported bug about these typedefs on x86_64 -mfpmath=387, as architecture-specific tests can be added that It is entirely possible that the fixed default makes some architecture-specific versions of bits/mathdef.h semantically equivalent to the default version and so no longer required. I don't intend to investigate that separately from the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, which will create as few header variants as possible for each group of definitions. Tested (compilation only) with build-many-glibcs.py. [BZ #20855] * bits/mathdef.h (float_t): Define to float. * math/test-flt-eval-method.c: New file. * math/Makefile (tests): Add test-flt-eval-method. (CFLAGS-test-flt-eval-method.c): New variable.
2016-11-23 00:28:30 +00:00
* On ColdFire, MicroBlaze, Nios II and SH3, the float_t type is now defined
to float instead of double. This does not affect the ABI of any libraries
that are part of the GNU C Library, but may affect the ABI of other
libraries that use this type in their interfaces.
More NEWS entries / fixes for float_t / double_t changes. Document changes for x86_64 -mfpmath=sse and -mfpmath=sse+387. Don't put these NEWS entries in the middle of TS 18661-1 entries.
2016-11-23 21:30:04 +00:00
* On x86_64, when compiling with -mfpmath=387 or -mfpmath=sse+387, the
float_t and double_t types are now defined to long double instead of float
and double. These options are not the default, and this does not affect
the ABI of any libraries that are part of the GNU C Library, but it may
affect the ABI of other libraries that use this type in their interfaces,
if they are compiled or used with those options.
Add strfromd, strfromf, and strfroml functions ISO/IEC TS 18661-1 adds several functions in the strfrom family to stdlib. This patch adds strfromd, strfromf, and strfroml. This is being done in preparation for the new floating-point type, float128. The added functions convert a floating-point value into a string, with configurable format.

Add getentropy, getrandom, <sys/random.h> [BZ #17252]
2016-12-12 16:28:03 +00:00
* The getentropy and getrandom functions, and the <sys/random.h> header file
have been added.
libio: Limit buffer size to 8192 bytes [BZ #4099] This avoids overly large buffers with network file systems which report very large block sizes.
2016-11-30 13:59:27 +00:00
* The buffer size for byte-oriented stdio streams is now limited to 8192
bytes by default. Previously, on Linux, the default buffer size on most
file systems was 4096 bytes (and thus remains unchanged), except on
network file systems, where the buffer size was unpredictable and could be
as large as several megabytes.
Base <sys/quota.h> on Linux kernel headers [BZ #20525] Macros which are also defined in <linux/quota.h> are removed, and <linux/quota.h> is included instead. This commit cleans up the definition of fs_to_dq_blocks and struct dqblock and struct dqinfo, too.
2016-09-01 13:53:13 +00:00
* The <sys/quota.h> header now includes the <linux/quota.h> header. Support
for the Linux quota interface which predates kernel version 2.4.22 has
been removed.
malloc: Remove malloc_get_state, malloc_set_state [BZ #19473] After the removal of __malloc_initialize_hook, newly compiled Emacs binaries are no longer able to use these interfaces. malloc_get_state is only used during the Emacs build process, so we provide a stub implementation only. Existing Emacs binaries will not call this stub function, but still reference the symbol. The rewritten tst-mallocstate test constructs a dumped heap which should approximates what existing Emacs binaries pass to glibc malloc.
2016-10-26 11:28:28 +00:00
* The malloc_get_state and malloc_set_state functions have been removed.
Already-existing binaries that dynamically link to these functions will
get a hidden implementation in which malloc_get_state is a stub. As far
as we know, these functions are used only by GNU Emacs and this change
will not adversely affect already-built Emacs executables. Any undumped
Emacs executables, which normally exist only during an Emacs build, should
be rebuilt by re-running “./configure; make” in the Emacs build tree.
resolv: Remove RES_NOIP6DOTINT and its implementation
2016-10-07 11:55:47 +00:00
* The “ip6-dotint” and “no-ip6-dotint” resolver options, and the
corresponding RES_NOIP6DOTINT flag from <resolv.h> have been removed.
“no-ip6-dotint” had already been the default, and support for the
“ip6-dotint” option was removed from the Internet in 2006.
Fix typo in NEWS The ip6-bytestring resolver corresponds to the RES_USEBSTRING flag and not RES_NOIP6DOTINT. Thank you Michael Kerrisk for noticing and pointing it out.
2017-01-14 11:07:41 +00:00
* The "ip6-bytestring" resolver option and the corresponding RES_USEBSTRING
resolv: Remove RES_USEBSTRING and its implementation [BZ #20629] In ns_name_ntop, the NS_CMPRSFLGS check is no longer needed because labellen (called earlier) already rejects everything which is not a plain label (compression references and extended label types).
2016-10-07 11:43:48 +00:00
flag from <resolv.h> have been removed. The option relied on a
backwards-incompatible DNS extension which was never deployed on the
Internet.
resolv: Deprecate RES_BLAST
2016-12-31 18:08:39 +00:00
* The flags RES_AAONLY, RES_PRIMARY, RES_NOCHECKNAME, RES_KEEPTSIG,
RES_BLAST defined in the <resolv.h> header file have been deprecated.
They were already unimplemented.
resolv: Deprecate unimplemented flags RES_AAONLY, RES_PRIMARY, RES_NOCHECKNAME, RES_KEEPTSIG result in compile-time warnings. Some of these flags are still used in applications.
2016-10-07 15:41:45 +00:00
resolv: Deprecate the "inet6" option and RES_USE_INET6 [BZ #19582]
2016-10-04 09:52:10 +00:00
* The "inet6" option in /etc/resolv.conf and the RES_USE_INET6 flag for
_res.flags are deprecated. The flag was standardized in RFC 2133, but
removed again from the IETF name lookup interface specification in RFC
2553. Applications should use getaddrinfo instead.
Remove obsolete DNSSEC support [BZ #20591] The removed function declaration have never been implemented in libresolv.
2016-09-21 14:08:31 +00:00
* DNSSEC-related declarations and definitions have been removed from the
<arpa/nameser.h> header file, and libresolv will no longer attempt to
decode the data part of DNSSEC record types. Previous versions of glibc
only implemented minimal support for the previous version of DNSSEC, which
is incompatible with the currently deployed version.
<arpa/nameser.h>: Remove RR type classification macros [BZ #20592] The macros are no longer up-to-date, and the classification is not useful. In this particular case, removal without prior deprecation seems the right approach.
2016-09-21 14:27:14 +00:00
* The resource record type classification macros ns_t_qt_p, ns_t_mrr_p,
ns_t_rr_p, ns_t_udp_p, ns_t_xfr_p have been removed from the
<arpa/nameser.h> header file because the distinction between RR types and
meta-RR types is not officially standardized, subject to revision, and
thus not suitable for encoding in a macro.
resolv: Remove unsupported hook functions from the API [BZ #20016]
2016-09-21 14:30:27 +00:00
* The types res_sendhookact, res_send_qhook, re_send_rhook, and the qhook
and rhook members of the res_state type in <resolv.h> have been removed.
The glibc stub resolver did not support these hooks, but the header file
did not reflect that.
Add configure check to test if gcc supports attribute ifunc. This patch adds a configure check to test if gcc supports attribute ifunc. The support can either be enabled in <gcc-src>/gcc/config.gcc for one architecture in general by setting default_gnu_indirect_function variable to yes or by configuring gcc with --enable-gnu-indirect-function. The next patch rewrites libc_ifunc macro to use gcc attribute ifunc instead of inline assembly to generate the IFUNC symbols due to false debuginfo. If gcc does not support attribute ifunc, the old approach for generating ifunc'ed symbols is used. Then the debug-information is false. Thus it is recommended to use a gcc with indirect function support (See notes in INSTALL). After this patch-series these inline assemblies for ifunc-handling are not scattered in multiple files but are used only indirect via ifunc-macros and can simply removed in libc-symbols.h in future. If glibc is configured with --enable-multi-arch and gcc does not support attribute ifunc, a configure warning is dumped! ChangeLog: * config.h.in (HAVE_GCC_IFUNC): New undef. * configure.ac: Add check if gcc supports attribute ifunc feature. * configure: Regenerated. * manual/install.texi: Add recommendation for gcc with indirect-function support. * INSTALL: Regenerated.
2016-10-07 07:56:46 +00:00
* For multi-arch support it is recommended to use a GCC which has
been built with support for GNU indirect functions. This ensures
that correct debugging information is generated for functions
selected by IFUNC resolvers. This support can either be enabled by
configuring GCC with '--enable-gnu-indirect-function', or by
enabling it by default by setting 'default_gnu_indirect_function'
variable for a particular architecture in the GCC source file
'gcc/config.gcc'.
Add pretty printers for the NPTL lock types This patch adds pretty printers for the following NPTL types: - pthread_mutex_t - pthread_mutexattr_t - pthread_cond_t - pthread_condattr_t - pthread_rwlock_t - pthread_rwlockattr_t To load the pretty printers into your gdb session, do the following: python import sys sys.path.insert(0, '/path/to/glibc/build/nptl/pretty-printers') end source /path/to/glibc/source/pretty-printers/nptl-printers.py You can check which printers are registered and enabled by issuing the 'info pretty-printer' gdb command. Printers should trigger automatically when trying to print a variable of one of the types mentioned above. The printers are architecture-independent, and were tested on an AMD64 running Ubuntu 14.04 and an x86 VM running Fedora 24. In order to work, the printers need to know the values of various flags that are scattered throughout pthread.h and pthreadP.h as enums and #defines. Since replicating these constants in the printers file itself would create a maintenance burden, I wrote a script called gen-py-const.awk that Makerules uses to extract the constants. This script is pretty much the same as gen-as-const.awk, except it doesn't cast the constant values to 'long' and is thorougly documented. The constants need only to be enumerated in a .pysym file, which is then referenced by a Make variable called gen-py-const-headers. As for the install directory, I discussed this with Mike Frysinger and Siddhesh Poyarekar, and we agreed that it can be handled in a separate patch, and shouldn't block merging of this one. In addition, I've written a series of test cases for the pretty printers. Each lock type (mutex, condvar and rwlock) has two test programs, one for itself and other for its related 'attributes' object. Each test program in turn has a PExpect-based Python script that drives gdb and compares its output to the expected printer's. The tests run on the glibc host, which is assumed to have both gdb and PExpect; if either is absent the tests will fail with code 77 (UNSUPPORTED). For cross-testing you should use cross-test-ssh.sh as test-wrapper. I've tested the printers on both native builds and a cross build using a Beaglebone Black running Debian, with the build system's filesystem shared with the board through NFS. Finally, I've written a README that explains all this and more. * INSTALL: Regenerated. * Makeconfig: Add comments and whitespace to make the control flow clearer. (+link-printers-tests, +link-pie-printers-tests, CFLAGS-printers-tests, installed-rtld-LDFLAGS, built-rtld-LDFLAGS, link-libc-rpath, link-libc-tests-after-rpath-link, link-libc-printers-tests): New.

Version 2.24
Require Linux 3.2 except on x86 / x86_64, 3.2 headers everywhere. In <https://sourceware.org/ml/libc-alpha/2016-01/msg00885.html> I proposed a minimum Linux kernel version of 3.2 for glibc 2.24, since Linux 2.6.32 has reached EOL. In the discussion in February, some concerns were expressed about compatibility with OpenVZ containers. It's not clear that these are real issues, given OpenVZ backporting kernel features and faking the kernel version for guest software, as discussed in <https://sourceware.org/ml/libc-alpha/2016-02/msg00278.html>. It's also not clear that supporting running GNU/Linux distributions from late 2016 (at the earliest) on a kernel series from 2009 is a sensible expectation. However, as an interim step, this patch increases the requirement everywhere except x86 / x86_64 (since the controversy was only about those architectures); the special caveats and settings can easily be removed later when we're ready to increase the requirements on x86 / x86_64 (and if someone would like to raise the issue on LWN as suggested in the previous discussion, that would be welcome). 3.2 kernel headers are required everywhere by this patch. (x32 already requires 3.4 or later, so is unaffected by this patch.) As usual for such a change, this patch only changes the configure scripts and associated documentation. The intent is to follow up with removal of dead __LINUX_KERNEL_VERSION conditionals. Each __ASSUME_* or other macro that becomes dead can then be removed independently. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/configure.ac (LIBC_LINUX_VERSION): Define to 3.2.0. (arch_minimum_kernel): Likewise. * sysdeps/unix/sysv/linux/configure: Regenerated. * sysdeps/unix/sysv/linux/i386/configure.ac (arch_minimum_kernel): Define to 2.6.32. * sysdeps/unix/sysv/linux/i386/configure: Regenerated. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac (arch_minimum_kernel): Define to 2.6.32. * sysdeps/unix/sysv/linux/x86_64/64/configure: Regenerated. * README: Document Linux 3.2 requirement. * manual/install.texi (Linux): Document Linux 3.2 headers requirement. * INSTALL: Regenerated.
2016-02-24 17:15:12 +00:00
* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 3.2, except on i[4567]86 and x86_64, where Linux
kernel version 2.6.32 or later suffices (on architectures that already
required kernel versions more recent than 3.2, those requirements remain
unchanged). Linux 3.2 or later kernel headers are required on all
architectures.

Remove union wait [BZ #19613] The overloading approach in the W* macros was incompatible with integer expressions of a type different from int. Applications using union wait and these macros will have to migrate to the POSIX-specified int status type.

* The type “union wait” has been removed. It was deprecated in the early
1990s and never part of POSIX. Application code should use the int type
instead of “union wait”.
NSS: Implement group merging support. https://sourceware.org/glibc/wiki/Proposals/GroupMerging == Justification == It is common today for users to rely on centrally-managed user stores for handling their user accounts. However, much software existing today does not have an innate understanding of such accounts. Instead, they commonly rely on membership in known groups for managing access-control (for example the "wheel" group on Fedora and RHEL systems or the "adm" group on Debian-derived systems). In the present incarnation of nsswitch, the only way to have such groups managed by a remote user store such as FreeIPA or Active Directory would be to manually remove the groups from /etc/group on the clients so that nsswitch would then move past nss_files and into the SSSD, nss-ldap or other remote user database. == Solution == With this patch, a new action is introduced for nsswitch: NSS_ACTION_MERGE. To take advantage of it, one will add [SUCCESS=merge] between two database entries in the nsswitch.conf file. When a group is located in the first of the two group entries, processing will continue on to the next one. If the group is also found in the next entry (and the group name and GID are an exact match), the member list of the second entry will be added to the group object to be returned. == Implementation == After each DL_LOOKUP_FN() returns, the next action is checked. If the function returned NSS_STATUS_SUCCESS and the next action is NSS_ACTION_MERGE, a copy of the result buffer is saved for the next pass through the loop. If on this next pass through the loop the database returns another instance of a group matching both the group name and GID, the member list is added to the previous list and it is returned as a single object. If the following database does not contain the same group, then the original is copied back into the destination buffer. This patch implements merge functionality only for the group database. For other databases, there is a default implementation that will return the EINVAL errno if a merge is requested. The merge functionality can be implemented for other databases at a later time if such is needed. Each database must provide a unique implementation of the deep-copy and merge functions. If [SUCCESS=merge] is present in nsswitch.conf for a glibc version that does not support it, glibc will process results up until that operation, at which time it will return results if it has found them or else will simply return an error. In practical terms, this ends up behaving like the remainder of the nsswitch.conf line does not exist. == Iterators == This feature does not modify the iterator functionality from its current behavior. If getgrnam() or getgrgid() is called, glibc will iterate through all entries in the `group` line in nsswitch.conf and display the list of members without attempting to merge them. This is consistent with the behavior of nss_files where if two separate lines are specified for the same group in /etc/groups, getgrnam()/getgrgid() will display both. Clients are already expected to handle this gracefully. == No Premature Optimizations == The following is a list of places that might be eligible for optimization, but were not overengineered for this initial contribution: * Any situation where a merge may occur will result in one malloc() of the same size as the input buffer. * Any situation where a merge does occur will result in a second malloc() to hold the list of pointers to member name strings. * The list of members is simply concatenated together and is not tested for uniqueness (which is identical to the behavior for nss_files, which will simply return identical values if they both exist on the line in the file. This could potentially be optimized to reduce space usage in the buffer, but it is both complex and computationally expensive to do so. == Testing == I performed testing by running the getent utility against my newly-built glibc and configuring /etc/nsswitch.conf with the following entry: group: group: files [SUCCESS=merge] sss In /etc/group I included the line: wheel:x:10:sgallagh I then configured my local SSSD using the id_provider=local to respond with: wheel:*:10:localuser,localuser2 I then ran `getent group wheel` against the newly-built glibc in multiple situations and received the expected output as described above: * When SSSD was running. * When SSSD was configured in nsswitch.conf but the daemon was not running. * When SSSD was configured in nsswitch.conf but nss_sss.so.2 was not installed on the system. * When the order of 'sss' and 'files' was reversed. * All of the above with the [SUCCESS=merge] removed (to ensure no regressions). * All of the above with `getent group 10`. * All of the above with `getent group` with and without `enumerate=true` set in SSSD. * All of the above with and without nscd enabled on the system.
2016-04-30 02:11:09 +00:00
* A new NSS action is added to facilitate large distributed system
administration. The action, MERGE, allows remote user stores like LDAP
to be merged into local user stores like /etc/groups in order to provide
easy to use, updated, and managed sets of merged credentials. The new
action can be used by configuring it in /etc/nsswitch.conf:
group: files [SUCCESS=merge] nis

Add nextup and nextdown math functions TS 18661 adds nextup and nextdown functions alongside nextafter to provide support for float128 equivalent to it. This patch adds nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf to libm before float128 support. The nextup functions return the next representable value in the direction of positive infinity and the nextdown functions return the next representable value in the direction of negative infinity. These are currently enabled as GNU extensions.

leak for each thread which is created, performs a failing naming lookup,
and exits. Over time, this could result in a denial of service due to
memory exhaustion. Reported by Matthias Schiffer. (CVE-2016-5417)

Updated __nonnull annotations for wcscat, wcsncat, wcscmp and wcsncmp [BZ #18265] This patch adds __nonnull annotations for wcscat, wcsncat, wcscmp and wcsncmp. These added annotations match the annoations for strcat, strncat, strcmp, strncmp in glibc.
2015-05-22 08:00:26 +00:00
Version 2.23
Update to Unicode 8.0.0. Update __STDC_ISO_10646__ to 201505L for Unicode 8.0.0. Update character encoding, ctype, and transliteration tables. New scripts autogenerate transliteration tables.
2015-12-10 05:30:51 +00:00
* Unicode 8.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 8.0.0, using new
and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, such as the fixes for bugs
89, 16061, and 18568.
Remove CPU set size checking from affinity functions [BZ #19143] With current kernel versions, the check does not reliably detect that unavailable CPUs are requested, for these reasons: (1) The kernel will silently ignore non-allowed CPUs, that is, CPUs which are physically present but disallowed for the thread based on system configuration. (2) Similarly, CPU bits which lack an online CPU (possible CPUs) are ignored. (3) The existing probing code assumes that the CPU mask size is a power of two and at least 1024. Neither has it to be a power of two, nor is the minimum possible value 1024, so the value determined is often too large. This means that the CPU set size check in glibc accepts CPU bits beyond the actual hard system limit. (4) Future kernel versions may not even have a fixed CPU set size. After the removal of the probing code, the kernel still returns EINVAL if no CPU in the requested set remains which can run the thread after the affinity change. Applications which care about the exact affinity mask will have to query it using sched_getaffinity after setting it. Due to the effects described above, this commit does not change this. The new tests supersede tst-getcpu, which is removed. This addresses bug 19164 because the new tests allocate CPU sets dynamically. * nptl/check-cpuset.h: Remove. * nptl/pthread_attr_setaffinity.c (__pthread_attr_setaffinity_new): Remove CPU set size check. * nptl/pthread_setattr_default_np.c (pthread_setattr_default_np): Likewise. * sysdeps/unix/sysv/linux/check-cpuset.h: Remove. * sysdeps/unix/sysv/linux/pthread_setaffinity.c (__kernel_cpumask_size, __determine_cpumask_size): Remove.

Add tst-affinity, tst-affinity-pid. [$(subdir) == nptl] (tests): Add tst-thread-affinity-pthread, tst-thread-affinity-pthread2, tst-thread-affinity-sched. * sysdeps/unix/sysv/linux/tst-affinity.c: New file. * sysdeps/unix/sysv/linux/tst-affinity-pid.c: New file. * sysdeps/unix/sysv/linux/tst-skeleton-affinity.c: New skeleton test file. * sysdeps/unix/sysv/linux/tst-thread-affinity-sched.c: New file. * sysdeps/unix/sysv/linux/tst-thread-affinity-pthread.c: New file. * sysdeps/unix/sysv/linux/tst-thread-affinity-pthread2.c: New file. * sysdeps/unix/sysv/linux/tst-thread-skeleton-affinity.c: New skeleton test file. * sysdeps/unix/sysv/linux/tst-getcpu.c: Remove. Superseded by tst-affinity-pid.
2015-11-24 16:21:01 +00:00
* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
kernel-internal CPU set size. This means that requests that change the
CPU affinity which failed before (for example, an all-ones CPU mask) will
now succeed. Applications that need to determine the effective CPU
affinities need to call sched_getaffinity or pthread_getaffinity_np after
setting it because the kernel can adjust it (and the previous size check
would not detect this in the majority of cases).
Add LFS support for fts functions (bug 11460) fts didn't have large-file support yet and fts.h had an #error preventing usage when _FILE_OFFSET_BITS was set. This required nasty workarounds for programs using fts with LFS. This patch implements LFS support for fts by adding FTS64 and FTENT64 variants plus fts64 functions. Which are simple aliases for 64bit off_t arches. Also includes a simple testcase for some of the fts functions with or without LFS enabled. [BZ #11460] * io/Makefile (routines): Add fts64.

Terminate process on invalid netlink response from kernel [BZ #12926] The recvmsg system calls for netlink sockets have been particularly prone to picking up unrelated data after a file descriptor race (where the descriptor is closed and reopened concurrently in a multi-threaded process, as the result of a file descriptor management issue elsewhere). This commit adds additional error checking and aborts the process if a datagram of unexpected length (without the netlink header) is received, or an error code which cannot happen due to the way the netlink socket is used.

socket. If such responses are received, an affected process will
terminate with an error message of "Unexpected error <number> on netlink
descriptor <number>" or "Unexpected netlink response of size <number> on
descriptor <number>". The most likely cause for these errors is a
multi-threaded application which erroneously closes and reuses the netlink
file descriptor while it is used by getaddrinfo.

S390: Optimize string, wcsmbs and memory functions. This patch set introduces optimized string, wcsmbs and memory functions for S390/S390x. The functions are accelerated by the usage of the new z13 vector instructions. The Principles of Operations manual for IBM z13 is publically available: http://publibfi.boulder.ibm.com/epubs/pdf/dz9zr010.pdf The support for these instructions in assembler was introduced by commits: -"[Committed] S/390: Add support for IBM z13." (https://sourceware.org/ml/binutils/2015-01/msg00197.html) -"[Committed] S/390: Add more IBM z13 instructions" (https://sourceware.org/ml/binutils/2015-03/msg00088.html) The first patches do preparation for the latter optimization patches. The floating point exception handling - fetestexcept(), ... - is fixed and the platform and hwcap strings are extended. The current ifunc routines memset, memcpy and memcmp are refactored and the ifunc test-framework is now enabled. A S390 specific configure-check tests if the used binutils supports the new vector instructions. The optimized functions are provided via ifunc if the binutils supports the vector instructions. Otherwise a message is dumped to configure output and only the currently used common code functions are available. The optimized functions are implemented in common for s390-32 and s390-64 and the few differences are handled via #ifdef. The ifunc-resolvers are defined in files sysdeps/s390/multiarch/<func>.c, which choose either the current implementation __<func>_c() or the vector implementation __<func>_vx() depending on the HWCAP_S390_VX flag bit in AT_HWCAP field. If the bit is set, the hardware and the kernel are supporting vector registers and instructions. If the used binutils lacks vector-support, then the default implementation in string or wcsmbs directory is included here instead. The file sysdeps/s390/multiarch/<func>-c.c includes the current implementation and defines the function name __<func>_c. The assembler files sysdeps/s390/multiarch/<func>-vx.S with the vector instructions are using the directive '.machine "z13"' to allow building glibc without option '-march=z13'. Additionally the directive '.machinemode "zarch_nohighgprs"' is needed for the 31bit glibc. This mode does not set the highgprs flag in ELF header, which would lead to an unloadable libc on a 31bit kernel. The most optimized string functions are structured in the same way: The first 16 bytes of the string is loaded unaligned via vlbb - vector load to block boundary (e.g. 4k). This instruction loads 16 bytes if possible. In case of a page cross, it only loads the last bytes of the current page without a segmentation fault. Afterwards these first part of string is processed. If e.g. for strlen the end of string is reached within this first part, the function returns. Otherwise the pointer is aligned to 16 byte, so i can load a full vector register with vl without checking for a page cross. Afterwards the first part of string is processed. If e.g. for strlen the end of string is reached within this first part, the function returns. Otherwise the pointer is aligned to 16 byte, so a full vector register can be loaded with vl - vector load - without checking for a page cross. The remaining string is processed in a four times unrolled loop, because benchmark results measured improvements compared to a non unrolled loop. The optimized wide string functions can only handle 4byte aligned string pointers. Although a wchar_t pointer should always be 4byte aligned, the most current common code wide string functions can handle non aligned strings. Thus the optimized functions will fall back to the common code functions in case of a non aligned wide string to behave the same as before this patch. Some string tests can test the string and the wide string version of a function. The remaining ones are extended and new wide string tests are added. This is the same in case of the benchtests.

Make obsolete syscall wrappers into compat symbols (bug 18472). Various Linux kernel syscalls have become obsolete over time. Specifically, the following are obsolete in all kernel versions supported by glibc, are not present for architectures more recently added to the kernel, and as such, the wrapper functions for them should be compat symbols, not in static libc and not available for new links with shared libc. * bdflush: in Linux 2.6, does nothing if present. * create_module get_kernel_syms query_module: Linux 2.4 module interface, syscalls not present in Linux 2.6. * uselib: part of the mechanism for loading a.out shared libraries, irrelevant with ELF. This patch adds support for syscalls.list to list syscall aliases of the form NAME@VERSION:OBSOLETED, with SHLIB_COMPAT conditionals being generated for such aliases. Those five syscalls are then made into compat symbols (obsoleted in glibc 2.23, so future ports won't have these symbols at all), with the header <sys/kdaemon.h> declaring bdflush being removed. When we move to 3.2 as minimum kernel version, the same can be done for nfsservctl (removed in Linux 3.1) as well. Tested for x86_64 and x86 (testsuite, as well as checking that the symbols in question indeed become compat symbols, that they are indeed omitted from static libc, and that the generated SHLIB_COMPAT conditionals look right). [BZ #18472] * sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Handle entries for the form NAME@VERSION:OBSOLETED and generate SHLIB_COMPAT conditionals for them. * sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Likewise. * sysdeps/unix/sysv/linux/sys/kdaemon.h: Remove file. * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Remove sys/kdaemon.h. * sysdeps/unix/sysv/linux/syscalls.list (bdflush): Make into compat-only syscall, obsoleted in glibc 2.23. (create_module): Likewise. (get_kernel_syms): Likewise. (query_module): Likewise. (uselib): Likewise. * manual/sysinfo.texi (System Parameters): Do not mention bdflush.

* The obsolete functions bdflush, create_module, get_kernel_syms,
query_module and uselib are no longer available to newly linked binaries;
the header <sys/kdaemon.h> has been removed. These functions and header

Require GCC 4.7 or later to build glibc. This patch implements a requirement of GCC 4.7 or later to build glibc. This was discussed in the thread starting at <https://sourceware.org/ml/libc-alpha/2015-08/msg00851.html>. Concerns were expressed by Mike and David. At <https://sourceware.org/ml/libc-alpha/2015-10/msg00453.html> I have provided a 14-patch series showing in outline the cleanups facilitated by this version requirement, as requested by Mike (this patch is the first in that series, with the addition of a NEWS entry). Given the absence of further concerns or alternative proposals for criteria for updates to this version requirement as requested in <https://sourceware.org/ml/libc-alpha/2015-10/msg00065.html>, I am interpreting this as "absence of sustained opposition" under Carlos's definition at <https://sourceware.org/glibc/wiki/Consensus> and proposing this patch for inclusion in glibc. I'd like to remind people testing with 4.6 that if they move to testing with GCC 5 then it will probably be about four years before they need to update the compiler they use to test glibc again. Although on the principles of time-based updates I think a move to requiring binutils 2.23 would be reasonable, I'm not currently aware of any cleanups that would facilitate so am not proposing that at this time (but would expect to propose a move to requiring binutils 2.24 in a year's time, as that brings features such as AVX512 support that should allow some conditionals to be cleaned up). If someone thinks a move to requiring 2.23 would help clean things up for their architecture, please speak up. (And in general, I suspect there are lots of architecture-specific configure tests that could be removed on the basis of current GCC and binutils version requirements, given how I've found architecture-independent tests obsolete on the basis of version requirements going back 20 years.) Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_compiler_ok): Require GCC 4.7 or later. * configure: Regenerated. * manual/install.texi (Tools for Compilation): Document requirement for GCC 4.7 or later. * INSTALL: Regenerated.

Fix lgamma setting signgam for ISO C (bug 15421). The lgamma (and likewise lgammaf, lgammal) function wrongly sets the signgam variable even when building for strict ISO C conformance (-std=c99 / -std=c11), although the user may define such a variable and it's only in the implementation namespace for POSIX with XSI extensions enabled. Following discussions starting at <https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems that the safest approach for fixing this particular issue is for signgam to become a weak alias for a newly exported symbol __signgam, with the library functions only setting __signgam, at which point static linker magic will preserve the alias for newly linked binaries that refer to the library's signgam rather than defining their own, while breaking the alias for programs that define their own signgam, with new symbol versions for lgamma functions and with compat symbols for existing binaries that set both signgam and __signgam. This patch implements that approach for the fix. signgam is made into a weak alias. The four symbols __signgam, lgamma, lgammaf, lgammal get new symbol versions at version GLIBC_2.23, with the existing versions of lgamma, lgammaf and lgammal becoming compat symbols. When the compat versions are built, gamma, gammaf and gammal are aliases for the compat versions (i.e. always set signgam); this is OK as they are not ISO C functions, and avoids adding new symbol versions for them unnecessarily. When the compat versions are not built (i.e. for static linking and for future glibc ports), gamma, gammaf and gammal are aliases for the new versions that set __signgam. The ldbl-opt versions are updated accordingly. The lgamma wrappers are adjusted so that the same source files, included from different files with different definitions of USE_AS_COMPAT, can build either the new versions or the compat versions. Similar changes are made to the ia64 versions (untested). Tests are added that the lgamma functions do not interfere with a user variable called signgam for ISO C, with various choices for the size of that variable, whether it is initialized, and for static and dynamic linking. The conformtest whitelist entry is removed as well. Tested for x86_64, x86, mips64 and powerpc, including looking at objdump --dynamic-syms output to make sure the expected sets of symbols were aliases. Also spot-tested that a binary built with old glibc works properly (i.e. gets signgam set) when run with new glibc.

Fix nan functions handling of payload strings (bug 16961, bug 16962). The nan, nanf and nanl functions handle payload strings by doing e.g.: if (tagp[0] != '\0') { char buf[6 + strlen (tagp)]; sprintf (buf, "NAN(%s)", tagp); return strtod (buf, NULL); } This is an unbounded stack allocation based on the length of the argument. Furthermore, if the argument starts with an n-char-sequence followed by ')', that n-char-sequence is wrongly treated as significant for determining the payload of the resulting NaN, when ISO C says the call should be equivalent to strtod ("NAN", NULL), without being affected by that initial n-char-sequence. This patch fixes both those problems by using the __strtod_nan etc. functions recently factored out of strtod etc. for that purpose, with those functions being exported from libc at version GLIBC_PRIVATE. Tested for x86_64, x86, mips64 and powerpc. [BZ #16961] [BZ #16962] * math/s_nan.c (__nan): Use __strtod_nan instead of constructing a string on the stack for strtod. * math/s_nanf.c (__nanf): Use __strtof_nan instead of constructing a string on the stack for strtof. * math/s_nanl.c (__nanl): Use __strtold_nan instead of constructing a string on the stack for strtold. * stdlib/Versions (libc): Add __strtof_nan, __strtod_nan and __strtold_nan to GLIBC_PRIVATE. * math/test-nan-overflow.c: New file. * math/test-nan-payload.c: Likewise. * math/Makefile (tests): Add test-nan-overflow and test-nan-payload.

CVE-2015-7547: getaddrinfo() stack-based buffer overflow (Bug 18665). * A stack-based buffer overflow was found in libresolv when invoked from libnss_dns, allowing specially crafted DNS responses to seize control of execution flow in the DNS client. The buffer overflow occurs in the functions send_dg (send datagram) and send_vc (send TCP) for the NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC family. The use of AF_UNSPEC triggers the low-level resolver code to send out two parallel queries for A and AAAA. A mismanagement of the buffers used for those queries could result in the response of a query writing beyond the alloca allocated buffer created by _nss_dns_gethostbyname4_r. Buffer management is simplified to remove the overflow. Thanks to the Google Security Team and Red Hat for reporting the security impact of this issue, and Robert Holiday of Ciena for reporting the related bug 18665.

soft-fp: Fix _FP_FMA when product is zero and third argument is finite (bug 17932). soft-fp's _FP_FMA fails to set the result's exponent for cases where the result of the multiplication is 0, yielding incorrect (arbitrary, depending on uninitialized values) results for those cases. This affects libm for architectures using soft-fp to implement fma. This patch adds the exponent setting and tests for this case. Tested for ARM soft-float (which uses soft-fp fma), x86_64 and x86 (to verify not introducing new libm test failures there). (This bug showed up in testing my patch to move the Linux kernel to current soft-fp. math/Makefile has "override CFLAGS += -Wno-uninitialized" which would have stopped compiler warnings from showing up this problem, although I wouldn't be surprised if removing that shows spurious warnings from this code, if the compiler fails to follow that various cases where the exponent is uninitialized don't need it initialized because the class is set to a value meaning the uninitialized exponent isn't used.) [BZ #17932] * soft-fp/op-common.h (_FP_FMA): Set exponent of result in case where multiplication results in zero and third argument is finite and nonzero. * math/auto-libm-test-in: Add more tests of fma. * math/auto-libm-test-out: Regenerated.

Version 2.22
* The following bugs are resolved with this release:
Mark bug 2981 (elf/tst-audit* fail on MIPS) as fixed. Changes in support of -fno-plt also cause the elf/tst-audit* tests to start passing on MIPS. This patch duly marks the relevant bug as fixed in ChangeLog and NEWS.

CVE-2015-1781: resolv/nss_dns/dns-host.c buffer overflow [BZ#18287]
2015-04-21 12:06:31 +00:00
* A buffer overflow in gethostbyname_r and related functions performing DNS
requests has been fixed. If the NSS functions were called with a
misaligned buffer, the buffer length change due to pointer alignment was
not taken into account. This could result in application crashes or,
potentially arbitrary code execution, using crafted, but syntactically
valid DNS responses. (CVE-2015-1781)

Make time zone file parser more robust [BZ #17715]
2015-04-24 15:34:47 +00:00
* The time zone file parser has been made more robust against crafted time
zone files, avoiding heap buffer overflows related to the processing of
the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
large time zone data files. Overly long time zone specifiers in the TZ
variable no longer result in stack overflows and crashes.
powerpc __tls_get_addr call optimization This patch is glibc support for a PowerPC TLS optimization, inspired by Alexandre Oliva's TLS optimization for other processors, http://www.lsd.ic.unicamp.br/~oliva/writeups/TLS/RFC-TLSDESC-x86.txt In essence, this optimization uses a zero module id in the tls_index GOT entry to indicate that a TLS variable is allocated space in the static TLS area. A special plt call linker stub for __tls_get_addr checks for such a tls_index and if found, returns the offset immediately. The linker communicates the fact that the special __tls_get_addr stub is used by setting a bit in the dynamic tag DT_PPC64_OPT/DT_PPC_OPT. glibc communicates to the linker that this optimization is available by the presence of __tls_get_addr_opt. tst-tlsmod2.so is built with -Wl,--no-tls-get-addr-optimize for tst-tls-dlinfo, which otherwise would fail since it tests that no static tls is allocated. The ld option --no-tls-get-addr-optimize has been available since binutils-2.20 so doesn't need a configure test. * NEWS: Advertise TLS optimization. * elf/elf.h (R_PPC_TLSGD, R_PPC_TLSLD, DT_PPC_OPT, PPC_OPT_TLS): Define.

libio: fmemopen rewrite to POSIX compliance This patch added a new fmemopen version, for glibc 2.22, that aims to be POSIX complaint. It fixes some long-stading glibc fmemopen issues, such as: * it changes the way fseek with SEEK_END works on fmemopen to seek relative to buffer size instead of first '\0'.

sparc: fix sigaction for 32bit builds [BZ #18694] Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction struct to pass conform tests, but it ended up also changing the ABI for 32 bit builds. For 64 bit builds, changing the long to two ints works, but for 32 bit builds, it inserts 4 extra bytes. This leads to many packages randomly failing like bash that spews things like: configure: line 471: wait_for: No record of process 0 Bracket the new member by a wordsize check to fix the ABI for 32bit.
2015-07-20 11:29:15 +00:00
* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
releases. It has been fixed to match 2.19 and older, but binaries built
against 2.20 and 2.21 might need to be recompiled. See BZ#18694.

Deprecate the use of regexp.h <regexp.h> (not to be confused with <regex.h>) is an obsolete and frankly horrible regular expression-matching API. It was part of SVID but was withdrawn in Issue 5 (for reference, we're on Issue 7 now). It doesn't do anything you can't do with <regex.h>, and using it involves defining a bunch of macros before including the header. Moreover, the code in regexp.h that uses those macros has been buggy since its creation (in 1996) and no one has noticed, which indicates to me that there are no users. (Specifically, RETURN() is used in a whole bunch of cases where it should have been ERROR().) The header is given a warning and marked deprecated for 2.22.

soft-fp: Fix _FP_FMA when product is zero and third argument is finite (bug 17932). soft-fp's _FP_FMA fails to set the result's exponent for cases where the result of the multiplication is 0, yielding incorrect (arbitrary, depending on uninitialized values) results for those cases. This affects libm for architectures using soft-fp to implement fma. This patch adds the exponent setting and tests for this case. Tested for ARM soft-float (which uses soft-fp fma), x86_64 and x86 (to verify not introducing new libm test failures there). (This bug showed up in testing my patch to move the Linux kernel to current soft-fp. math/Makefile has "override CFLAGS += -Wno-uninitialized" which would have stopped compiler warnings from showing up this problem, although I wouldn't be surprised if removing that shows spurious warnings from this code, if the compiler fails to follow that various cases where the exponent is uninitialized don't need it initialized because the class is set to a value meaning the uninitialized exponent isn't used.) [BZ #17932] * soft-fp/op-common.h (_FP_FMA): Set exponent of result in case where multiplication results in zero and third argument is finite and nonzero. * math/auto-libm-test-in: Add more tests of fma. * math/auto-libm-test-out: Regenerated.

Return failure in getnetgrent only when all netgroups have been searched (#17363) The netgroups lookup code fails when one of the groups in the search tree is empty. In such a case it only returns the leaves of the tree after the blank netgroup. This is because the line parser returns a NOTFOUND status when the netgroup exists but is empty. The __getnetgrent_internal implementation needs to be fixed to try remaining groups if the current group is entry. This patch implements this fix. Tested on x86_64. [BZ #17363] * inet/getnetgrent_r.c (__internal_getnetgrent_r): Try next group if the current group is empty.

Fix semaphore destruction (bug 12674).

In the latter case, we keep a conservative estimate of whether there are any waiting threads in one bit of the field that counts the number of available tokens, thus allowing sem_post to atomically both add a token and determine whether it needs to call futex_wake.

* A new semaphore algorithm has been implemented in generic C code for all
machines. Previous custom assembly implementations of semaphore were
difficult to reason about or ensure that they were safe. The new version
of semaphore supports machines with 64-bit or 32-bit atomic operations.
The new semaphore algorithm is used by sem_init, sem_open, sem_post,
sem_wait, sem_timedwait, sem_trywait, and sem_getvalue.
CVE-2014-7817: wordexp fails to honour WRDE_NOCMD. The function wordexp() fails to properly handle the WRDE_NOCMD flag when processing arithmetic inputs in the form of "$((... ``))" where "..." can be anything valid. The backticks in the arithmetic epxression are evaluated by in a shell even if WRDE_NOCMD forbade command substitution. This allows an attacker to attempt to pass dangerous commands via constructs of the above form, and bypass the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD in exec_comm(), the only place that can execute a shell. All other checks for WRDE_NOCMD are superfluous and removed. We expand the testsuite and add 3 new regression tests of roughly the same form but with a couple of nested levels. On top of the 3 new tests we add fork validation to the WRDE_NOCMD testing. If any forks are detected during the execution of a wordexp() call with WRDE_NOCMD, the test is marked as failed. This is slightly heuristic since vfork might be used in the future, but it provides a higher level of assurance that no shells were executed as part of command substitution with WRDE_NOCMD in effect. In addition it doesn't require libpthread or libdl, instead we use the public implementation namespace function __register_atfork (already part of the public ABI for libpthread). Tested on x86_64 with no regressions.

powerpc: Optimized strncmp for POWER8/PPC64 This patch adds an optimized POWER8 strncmp. The implementation focus on speeding up unaligned cases follwing the ideas of power8 strcmp. The algorithm first check the initial 16 bytes, then align the first function source and uses unaligned loads on second argument only. Aditional checks for page boundaries are done for unaligned cases (where sources alignment are different).

powerpc: Optimized st{r,p}cpy for POWER8/PPC64 This patch adds an optimized POWER8 strcpy using unaligned accesses. For strings up to 16 bytes the implementation first calculate the string size, like strlen, and issues a memcpy. For larger strings, source is first aligned to 16 bytes and then tested over a loop that reads 16 bytes am combine the cmpb results for speedup. Special case is added for page cross reads. It shows 30%-60% improvement over the optimized POWER7 one that uses only aligned accesses.

powerpc: Add the lock elision using HTM This patch adds support for lock elision using ISA 2.07 hardware transactional memory instructions for pthread_mutex primitives. Similar to s390 version, the for elision logic defined in 'force-elision.h' is only enabled if ENABLE_LOCK_ELISION is defined. Also, the lock elision code should be able to be built even with a compiler that does not provide HTM support with builtins. However I have noted the performance is sub-optimal due scheduling pressures.
2014-11-07 17:25:32 +00:00
* Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64
and powerpc64le. This may improve lock scaling of existing programs on
HTM capable systems. The lock elision code is only enabled with
--enable-lock-elision=yes. Also, the TSX lock elision implementation for
powerpc will issue a transaction abort on every syscall to avoid side
effects being visible outside transactions.

Require GCC 4.6 or later to build glibc. As discussed in the thread starting at <https://sourceware.org/ml/libc-alpha/2014-10/msg00792.html>, and continuing into November, this patch increases the minimum GCC version for building glibc to 4.6 (there seemed to be no clear consensus for 4.7). In particular, this allows us to use #pragma GCC diagnostic for fine-grained warning control with -Werror (subject to establishing a suitable policy for that use). The documentation has a statement, as requested, about the most recent GCC version tested for building glibc, and I've updated <https://sourceware.org/glibc/wiki/Release> to refer to updating that statement. A NEWS entry is added for this change, although previous such changes didn't get them. Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by this patch). * configure.ac (libc_cv_compiler_ok): Require GCC 4.6 or later. * configure: Regenerated. * manual/install.texi (Tools for Compilation): Document a requirement of GCC 4.6 or later and that GCC 4.9 is the newest compiler verified to work. * INSTALL: Regenerated.
2014-11-14 18:00:34 +00:00
* The minimum GCC version that can be used to build this version of the GNU
C Library is GCC 4.6. Older GCC versions, and non-GNU compilers, can
still be used to compile programs using the GNU C Library.
Use -Werror by default, add --disable-werror. As discussed starting at <https://sourceware.org/ml/libc-alpha/2014-11/msg00323.html>, this patch makes the glibc build use -Werror by default to avoid accidentally adding new warnings to the build. The configure option --disable-werror can be used to disable this. -Wno-error=undef is temporarily used because the build isn't clean regarding -Wundef warnings. The idea is that once the remaining -Wundef warnings have been cleaned up (in at least one configuration), -Wno-error=undef will be removed. I get a clean build and test on x86_64 (GCC 4.9 branch) with this patch. The expectation is that this may well break the build for some other configurations, and people seeing such breakage should make appropriate fixes to fix or suppress the warnings for their configurations. In some cases that may involve using pragmas as the right fix (I think that will be right for the -Wno-inline issue for MIPS I referred to in <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, for example), in some cases -Wno-error in sysdeps makefiles (__restore_rt in MIPS sigaction, for example), in some cases substantive fixes for the warnings. Note that if, with a view to listing all the warnings then fixing them all, you just look for "warning:" in output from building and testing with --disable-werror, you'll see lots of warnings from the linker about functions such as tmpnam. Those warnings can be ignored - only compiler warnings are relevant to -Werror, not linker warnings. * configure.ac (--disable-werror): New configure option. (enable_werror): New AC_SUBST. * configure: Regenerated. * config.make.in (enable-werror): New variable. * Makeconfig [$(enable-werror) = yes] (+gccwarn): Add -Werror -Wno-error=undef.

The initial motivation was to include the plural.y changes which enable building with bison 3.0, but the majority of the other changes are merely cosmetic so it seemed like merging the whole directory was simpler than trying to take it piecemeal. The merge was done by copying across the latext gettext code and adding in a few small glibc changes that have been added over the years that seemed beneficial, as well as a couple of small build fixes that should be merged back to gettext. I also reverted the gettext commit: commit 279b57fc367251666f00e8e2b599b83703451afb Author: Bruno Haible <bruno@clisp.org> Date: Fri Jun 14 12:03:49 2002 +0000 Make absolute pathnames inside $LANGUAGE work. As it caused localedata/tst-setlocale3 to fail and it wasn't clear that glibc wanted that behaviour. The merge has dropped many uses of __glibc_likely/unlikely. This is intentional given that it eases merging. It seems to me that the cost of continually rewriting these lines when merging and the risk of adding bugs when doing so outweighs the benefits of using these macros when code is shared with another project. Tested with make check on x86_64. ChangeLog: 2014-12-11 Will Newton <will.newton@linaro.org> Merge gettext 0.19.3 into intl/.

NEWS for MIPS ABIs * NEWS: Announce support for new MIPS ABI extensions.
2015-01-06 15:06:14 +00:00
* Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
The original MIPS o32 hard-float ABI requires an FPU where double-precision
registers overlay two consecutive single-precision registers. MIPS32R2
introduced a new FPU mode (FR=1) where double-precision registers extend the
corresponding single-precision registers which is incompatible with the
o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both
require the use of FR=1 making a transition necessary. New o32 ABI
extensions enable users to migrate over time from the original o32 ABI
through to the updated o32 FP64 ABI. To achieve this the dynamic linker now
tracks the ABI of any loaded object and verifies that new objects are
compatible. Mode transitions will also be requested as required and
unsupportable objects will be rejected. The ABI checks include both soft and
hard float ABIs for o32, n32 and n64.
GCC 5 with GNU binutils 2.25 onwards:
It is strongly recommended that all o32 system libraries are built using the
new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
with the original and all new o32 ABI extensions. Configure a MIPS GCC
compiler using --with-fp-32=xx to set this by default.
Return failure in getnetgrent only when all netgroups have been searched (#17363) The netgroups lookup code fails when one of the groups in the search tree is empty. In such a case it only returns the leaves of the tree after the blank netgroup. This is because the line parser returns a NOTFOUND status when the netgroup exists but is empty. The __getnetgrent_internal implementation needs to be fixed to try remaining groups if the current group is entry. This patch implements this fix. Tested on x86_64. [BZ #17363] * inet/getnetgrent_r.c (__internal_getnetgrent_r): Try next group if the current group is empty.

ucontext_t in an ABI-relevant data structure that have already been rebuilt
against 2.19 headers will have to rebuilt again. This is necessary in any
case to revert the breakage in their ABI caused by the glibc change.

* Support for file description locks is added to systems running the
Linux kernel. The standard file locking interfaces are extended to
operate on file descriptions, not file descriptors, via the use of
F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks
are associated with an open file instead of a process.
Deduplicate setenv. Setenv contained a code path that was redundant as it could be handled in general case.

Increase minimum Linux kernel version to 2.6.32. This patch increases the minimum Linux kernel version for glibc to 2.6.32, as discussed in the thread starting at <https://sourceware.org/ml/libc-alpha/2014-01/msg00511.html>. This patch just does the minimal change to arch_minimum_kernel settings (and LIBC_LINUX_VERSION, which determines the minimum kernel headers version, as it doesn't make sense for that to be older than the minimum kernel that can be used at runtime). Followups would be expected to do, roughly and not necessarily precisely in this order: * Remove __LINUX_KERNEL_VERSION checks in kernel-features.h files where those checks are always true / always false for kernels 2.6.32 and above. * Otherwise simplify/improve conditionals in those files (for example, where defining once in the main file then undefining in architecture-specific files makes things clearer than having lots of separate definitions of the same macro), possibly fixing in the process cases where a macro should optimally have been defined for a given architecture but wasn't. (In the review in preparation for this version increase I checked what the right conditions should be for all macros in the main kernel-features.h whose definitions there would have been affected by the increase - but I only fixed that subset of the issues found where --enable-kernel=2.6.32 would have caused a kernel feature to be wrongly assumed to be present, not any cases where a feature is not assumed but could be assumed.) * Remove conditionals on __ASSUME_* where they can now be taken to be always-true, and the definitions when the macros are only used in Linux-specific files. * Split more architectures out of the main kernel-features.h (like ex-ports architectures), once various of the architecture conditionals there have been eliminated so the new architecture-specific files are no larger than actually necessary. Tested x86_64. 2014-03-27 Joseph Myers <joseph@codesourcery.com> [BZ #9894] * sysdeps/unix/sysv/linux/configure.ac (LIBC_LINUX_VERSION): Change to 2.6.32.

Do not terminate default test runs on test failure. This patch is an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> and <https://sourceware.org/ml/libc-alpha/2014-03/msg00180.html>. Normal practice for software testsuites is that rather than terminating immediately when a test fails, they continue running and report at the end on how many tests passed or failed. The principle behind the glibc testsuite stopping on failure was probably that the expected state is no failures and so any failure indicates a problem such as miscompilation. In practice, while this is fairly close to true for native testing on x86_64 and x86 (kernel bugs and race conditions can still cause intermittent failures), it's less likely to be the case on other platforms, and so people testing glibc run the testsuite with "make -k" and then examine the logs to determine whether the failures are what they expect to fail on that platform, possibly with some automation for the comparison. This patch switches the glibc testsuite to the normal convention of not stopping on failure - unless you use stop-on-test-failure=y, in which case it behaves essentially as it did before (and does not generate overall test summaries on failure). Instead, the summary tests.sum may contain tests that FAILed. At the end of the test run, any FAIL or ERROR lines from tests.sum are printed, and then it exits with error status if there were any such lines. In addition, build failures will also cause the test run to stop - this has the justification that those *do* indicate serious problems that should be promptly fixed and aren't generally hard to fix (but apart from that, avoiding the build stopping on those failures seems harder). Note that unlike the previous patches in this series, this *does* require people with automation around testing glibc to change their processes - either to start using tests.sum / xtests.sum to track failures and compare them with expectations (with or without also using "make -k" and examining "make" logs to identify build failures), or else to use stop-on-test-failure=y and ignore the new tests.sum / xtests.sum mechanism. (If all you check is the exit status from "make check", no changes are needed unless you want to avoid test runs continuing after the first failure.) Tested x86_64. * scripts/evaluate-test.sh: Handle fourth argument to determine whether test run should stop on failure. * Makeconfig (stop-on-test-failure): New variable. (evaluate-test): Pass fourth argument to evaluate-test.sh based on $(stop-on-test-failure). * Makefile (tests): Give a summary of results from testing and exit with failure status if they include an ERROR or FAIL. (xtests): Likewise. * manual/install.texi (Configuring and compiling): Mention stop-on-test-failure=y. * INSTALL: Regenerated.
2014-03-14 21:02:40 +00:00
* Running the testsuite no longer terminates as soon as a test fails.
Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
with PASS or FAIL lines for individual tests. A summary of the results is
printed, including a list of failing lists, and "make check" exits with
error status if there were any unexpected failures. "make check
stop-on-test-failure=y" may be used to keep the old behavior.
Remove am33 port. This patch removes the am33 port (no other port #includes any files from it), as previously discussed (see <https://sourceware.org/ml/libc-ports/2014-01/msg00046.html>).
2014-02-08 00:16:57 +00:00
* The am33 port, which had not worked for several years, has been removed
from ports.
Remove _BSD_SOURCE and _SVID_SOURCE. This is a minimal patch to remove _BSD_SOURCE and _SVID_SOURCE from the documented user API, making them into aliases for _DEFAULT_SOURCE with a #warning given, but keeping most of the features.h logic using those macros and all the exising __USE_* conditionals, on the basis that all the consequent cleanups will go in followup patches. Tested x86_64. * include/features.h: Update comment documenting feature test macros. [_BSD_SOURCE || _SVID_SOURCE]: Give #warning. Define _DEFAULT_SOURCE. * manual/creature.texi (_BSD_SOURCE): Remove documentation. (_SVID_SOURCE): Likewise. (_DEFAULT_SOURCE): Update description of default features. (Feature Test Macros): Don't mention _SVID_SOURCE in conjunction with _GNU_SOURCE. * manual/filesys.texi (__ftw_func_t): Do not refer to _BSD_SOURCE. (S_ISVTX): Likewise. * manual/math.texi (Mathematical Constants): Likewise. * manual/signal.texi (Interrupted Primitives): Likewise. * manual/startup.texi (putenv): Do not refer to _SVID_SOURCE. * math/test-matherr.c (_SVID_SOURCE): Do not define. * sysvipc/sys/ipc.h [__USE_SVID && !__USE_XOPEN && __GNUC__ >= 2]: Don't refer to _SVID_SOURCE in warning text.
2014-02-11 23:40:07 +00:00
* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
supported; they now act the same as _DEFAULT_SOURCE (but generate a
warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
conflicted with POSIX (support for which was removed in 2.19), the
interfaces those macros enabled remain available when compiling with
_GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
test macros defined.
ARM: Add optimized ARMv7 strcmp implementation Add an optimized implementation of strcmp for ARMv7-A cores. This implementation is significantly faster than the current generic C implementation, particularly for strings of 16 bytes and longer. Tested with the glibc string tests for arm-linux-gnueabihf and armeb-linux-gnueabihf. The code was written by ARM, who have agreed to assign the copyright to the FSF for integration into glibc.

S/390: Port of lock elision to System/z Added support for TX lock elision of pthread mutexes on s390 and s390x. This may improve lock scaling of existing programs on TX capable systems. The lock elision code is only built with --enable-lock-elision=yes and then requires a GCC version supporting the TX builtins. With lock elision default mutexes are elided via __builtin_tbegin, if the cpu supports transactions. By default lock elision is not enabled and the elision code is not built.

Update README and NEWS for ports directory removal. This patch updates README to remove a mention of the ports directory. It also adds a NEWS item for the merge of ports into the main sysdeps tree (I think it's NEWS-worthy, although not strictly a user-visible feature). Other remaining ports references to resolve: a comment in manual/signal.texi (not giving a literal path, but maybe should change anyway); a comment in config.h.in (path should be updated); scripts/list-sources.sh (appears to date back to ports being a separate repository). * README: Do not mention ports directory.
2014-06-25 12:55:21 +00:00

instead of some being in a separate "ports" directory (which was
distributed separately before glibc 2.17).

_nl_find_locale: Improve handling of crafted locale names [BZ #17137] Prevent directory traversal in locale-related environment variables (CVE-2014-0475).
2014-05-12 13:24:12 +00:00
* Locale names, including those obtained from environment variables (LANG
and the LC_* variables), are more tightly checked for proper syntax.
setlocale will now fail (with EINVAL) for locale names that are overly
long, contain slashes without starting with a slash, or contain ".." path
components. (CVE-2014-0475) Previously, some valid locale names were
silently replaced with the "C" locale when running in AT_SECURE mode
(e.g., in a SUID program). This is no longer necessary because of the
additional checks.
NEWS: Mention x86-64 ld.so use of Intel MPX instructions.
2014-08-12 16:49:58 +00:00
* On x86-64, the dynamic linker's lazy-binding support is now compatible
with application code using Intel MPX instructions. (With all previous
versions, the MPX register state could be clobbered when making calls
into or out of a shared library.) Note that while the new dynamic
linker is compatible with all known x86 hardware whether or not it
supports Intel MPX, some x86 instruction-set emulators might fail to
handle the new instruction encodings. This is known to affect Valgrind
versions up through 3.9 (but will be fixed in the forthcoming 3.10
release), and might affect other tools that do instruction emulation.

Check for integer overflow in cache size computation in strcoll strcoll is implemented using a cache for indices and weights of collation sequences in the strings so that subsequent passes do not have to search through collation data again. For very large string inputs, the cache size computation could overflow. In such a case, use the fallback function that does not cache indices and weights of collation sequences. Fixes CVE-2012-4412.
2013-09-23 05:54:30 +00:00
* CVE-2012-4412 The strcoll implementation caches indices and rules for
large collation sequences to optimize multiple passes. This cache
computation may overflow for large collation sequences and may cause a
stack or buffer overflow. This is now fixed to use a slower algorithm
which does not use a cache if there is an integer overflow.

Add _DEFAULT_SOURCE feature test macro. This patch adds a feature test macro _DEFAULT_SOURCE to enable the default set of header declarations. The intention is: if _DEFAULT_SOURCE is not used there is no change to the set of __USE_* macros glibc defines; if it's used on its own, and without compiler options such as -std=c99 that define __STRICT_ANSI__, again, there is no change; if it's used together with the macros it approximately (i.e., apart from __USE_POSIX_IMPLICITLY) implies (-D_BSD_SOURCE -D_SVID_SOURCE -D_POSIX_C_SOURCE=200809L), again, there is no change. Otherwise, it causes the relevant features to be enabled, even if __STRICT_ANSI__, or another feature test macro, would cause them to be disabled. This macro deliberately bundles the POSIX.1-2008 (non-X/Open) functionality with the BSD/SVID/"misc" functionality, rather than defining a macro that gives just the latter, as many of the header cleanups resulting from removing _BSD_SOURCE and _SVID_SOURCE support are only possible when BSD/SVID/"misc" is always bundled with POSIX.1-2008. Tested x86_64. * include/features.h: Update comment documenting feature test macros. Mention _DEFAULT_SOURCE in comment. [_GNU_SOURCE] (_DEFAULT_SOURCE): Undefine and redefine.

NEWS: Add comment about changed ABI on s390 and s390x.
2014-04-08 14:30:07 +00:00
* Change of ABI data structures for s390 and s390x:
On s390 and s390x the size of struct ucontext and jmp_buf was increased to
allow for future hardware extensions. All library functions that accept or
return these structures were versioned in order to provide backwards
compatibility with existing code. However, not all cases can be handled
with interface versioning. If an application embeds either structure into
another structure and that structure is passed to another compilation unit
which expects the newer larger-sized object then any access to the new
fields will result in undefined behaviour. Similarly any access to fields
that were moved by the enlarging of the structures will cause undefined
behaviour. To fix the undefined behaviour all objects that are part of the
final in-memory image must agree on the size of structures, and this may
require recompilation.

CVE-2013-2207, BZ #15755: Disable pt_chown. The helper binary pt_chown tricked into granting access to another user's pseudo-terminal. Pre-conditions for the attack: * Attacker with local user account * Kernel with FUSE support * "user_allow_other" in /etc/fuse.conf * Victim with allocated slave in /dev/pts Using the setuid installed pt_chown and a weak check on whether a file descriptor is a tty, an attacker could fake a pty check using FUSE and trick pt_chown to grant ownership of a pty descriptor that the current user does not own. It cannot access /dev/pts/ptmx however. In most modern distributions pt_chown is not needed because devpts is enabled by default. The fix for this CVE is to disable building and using pt_chown by default. We still provide a configure option to enable hte use of pt_chown but distributions do so at their own risk.

* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
has been fixed by disabling the use of pt_chown (Bugzilla #15755).
Distributions can re-enable building and using pt_chown via the new configure
option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
considerable security risks and should only be used if the distribution
understands and accepts the risks.

* Added support for version-3 tz format files. This is needed when using
the tz database release 2013e or later, and affects a few unusual cases --
currently only TZ='America/Godthab' for time stamps after 2037.
New API to set default thread attributes This patch introduces two new convenience functions to set the default thread attributes used for creating threads. This allows a programmer to set the default thread attributes just once in a process and then run pthread_create without additional attributes.
2013-06-15 06:54:15 +00:00
* Added new API functions pthread_getattr_default_np and
pthread_setattr_default_np to get and set the default pthread
attributes of a process.
Add lock elision to NEWS file
2013-07-02 15:49:30 +00:00
* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
This may improve lock scaling of existing programs on TSX capable systems.
When the --enable-lock-elision=yes parameter is specified at configure
time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
mutexes.
Added NEWS entries for AT_HWCAP2 and POWER8 enablement.
2013-07-25 15:49:13 +00:00

2012-08-03 13:42:47 +00:00
Add versions of wcscpy, wcschr, wcsrchr for power6/power7. Initially based on the versions found in wcsmbs/* ; these files have been changed by hand unrolling, and adding some additional variables to allow some read-ahead to occur, which then relieves some of the wait-for-increment/wait-for-load/wait-for-compare-results pressure that was slowing down every iteration through the while-loop. For 64-bit Power7, These changes give an approx 20% throughput boost for the wcschr and wcsrchr functions; and approx 40% boost for the wcscpy function. 32-bit improvements appear to be slightly better with ~ %30 and ~ %45 respectively. Results for Power6 closely match those for power7.
2012-08-22 16:04:42 +00:00
* Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
powerpc POWER7. Implemented by Will Schmidt.
BZ#13696: Add --disable-nscd configure option.
2012-08-22 20:31:12 +00:00

never attempts to contact the Name Service Caching Daemon (nscd).
Add --disable-build-nscd configure option.
2012-08-22 20:35:55 +00:00
New configure option --disable-build-nscd avoids building nscd itself;
this is the default if --disable-nscd is used.

Don't make ttyname* fail if proc filesystem is not available The ttyname and ttyname_r functions on Linux now fall back to searching for the tty file descriptor in /dev/pts or /dev if /proc is not available. This allows creation of chroots without the procfs mounted on /proc. Fixes BZ #14516.
2012-08-29 04:33:39 +00:00
* The ttyname and ttyname_r functions on Linux now fall back to searching for
the tty file descriptor in /dev/pts or /dev if /proc is not available. This
allows creation of chroots without the procfs mounted on /proc.
* NEWS: Add note about FIPS mode. Wording suggested by Roland McGrath.
2012-10-10 10:06:03 +00:00
* The `crypt' function now fails if passed salt bytes that violate the
specification for those values. On Linux, the `crypt' function will
consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
enabled, and fail on encrypted strings using the MD5 or DES algorithm
when the mode is enabled.
BZ#14743: Move clock_* symbols from librt to libc.
2012-10-24 21:50:46 +00:00
* The `clock_*' suite of functions (declared in <time.h>) is now available
directly in the main C library. Previously it was necessary to link with
-lrt to use these functions. This change has the effect that a
single-threaded program that uses a function such as `clock_gettime' (and
is not linked with -lrt) will no longer implicitly load the pthreads
library at runtime and so will not suffer the overheads associated with
multi-thread support in other code such as the C++ runtime library.

PowerPC added the first instance with a function to provide time base register access (__ppc_get_timebase). This is required for applications that measure time at high frequencies with high precision that can't afford a syscall.

the second request. The 'single-request-reopen' option in /etc/resolv.conf
can be used to select this mode right away, instead of rediscovering the
necessity is every process again.

servers (the case, e.g., for some people using the built-in DNS
server in ADSL modems/routers). There is a once-per-process timeout
in case of a broken server. To avoid it, users can run nscd or put
'options single-request' in /etc/resolv.conf.

efficiently.
Implemented by Ulrich Drepper.
* The nothrow function attribute is used when headers are used by gcc when
compiling C code. This can avoid significant amounts of exception
handling data.
* The malloc functions perform more error checking and are stricter when
it comes to reacting on errors. The default action is to terminate

namespaces using the new function dlmopen(). This feature is of course,
like most other dynamic loading functionality, not available in statically
linked applications. Implemented by Ulrich Drepper.
* Low-overhead boundary checking variants of string and some stdio functions
were added. These are to be used in conjunction with a gcc patch by
Jakub Jelinek which adds calls to these functions if possible.
* version.h (VERSION): 2.3.4. * README.template: Various updates. * README: Regenerated. * NEWS: Mention ports. * README-alpha: File removed.
2004-12-19 09:41:58 +00:00

* Old code for several operating systems and machine architectures that
have not been in working condition in a long time have been removed from
the main source tree maintained by the GNU C Library's maintainers.
These files are now reside in the separate `ports' source module
that is usable as an add-on when building the library.

* Thread-safe interfaces for many functions that access locale data
were added in version 2.3, but these features were omitted from NEWS.
Many functions have variants with an `_l' suffix that take a `locale_t'
object as a parameter rather than consulting the current locale.
The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
create and maintain `locale_t' objects. Additionally, the new function
`uselocale' sets "the current locale" (as used by functions not so
parameterized) set for an individual thread. These features were added
in version 2.3, implemented by Ulrich Drepper and Roland McGrath.

we can now check for namespace violations and missing declarations. The
result is that almost all headers are now Unix-compliant (as defined in
the upcoming XPG6). The negative side is that some programs might need
corrections, too, if they depend on the incorrect form of the headers in
previous versions which defined too many symbols and included too many
other headers.
Update.
2001-02-10 07:33:38 +00:00
* regex now handles multibyte character sets correctly.
Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
* iconv (the program) does now conform to the upcoming XPG6 and handles
charmaps. Instead of the charset names the path of charmaps can be
provided and the conversion happens based on this data.
Contributed by Ulrich Drepper.
* The locale program now provides detailed information about the installed
locales. While
locale -a
only lists the names of the supported locales
locale -a --verbose
provides details such as country, language, and codeset name.
Contributed by Ulrich Drepper.
Update. 2001-01-30 Ulrich Drepper <drepper@redhat.com> * iconv/gconv_open.c (__gconv_open): Set conv_flags if IGNORE is seen, not flags. * nis/nis_findserv.c: Include <time.h>.

2000-11-27 08:58:12 +00:00
Version 2.2.1
* The gencat program now parses the input file according to the charset
selected by the LC_CTYPE category. This is important for stateful
character sets. To make generating catalogs easier there is a way
to overwrite the charset selected by the locale: before the first
message or $ quote line the catalog can contain a line like
$ codeset=ISO-8859-2
to select the charset (ISO-8859-2 in this case).
Implemented by Shinya Hanataka and Ulrich Drepper.
Update. 2000-11-28 Ulrich Drepper <drepper@redhat.com> * sysdeps/i386/fpu/libm-test-ulps: Adjust some values for the crappy i486 FPU. Reported by Michael Deutschmann <michael@talamasca.ocis.net>.

2000-05-28 19:32:08 +00:00
This change could in some situations effect backward compatibility. Since
now `_res' is a thread-local instead of a global variable, modifying it
in one thread does not have any effect in other threads.
Update. 1999-12-13 Andreas Jaeger <aj@suse.de> * resolv/resolv.h: Remove K&R compatibility. * resolv/res_libc.c: Move definition of _res after res_init, res_init should use the threaded specific context. * resolv/Makefile (+cflags): Remove -Wno-comment since it's not needed anymore. * locale/langinfo.h: Add constants for wide character collation data. * locale/categories.def: Add appropriate entries for collate entries. * locale/C-collate.c: Add initializers for new entries. * locale/programs/ld-collate.c: Implement output of wide character tables. * locale/programs/ld-ctype.c (allocate_arrays): Change algorithm to compute wide character table size a bit: it now gives up a bit of total table size for fewer levels.

* Richard Henderson corrected size of struct timeval on Linux/Alpha to
conform to POSIX member type requirements. Symbol versions have been
adjusted as needed within the library, and for direct use by applications,
but there is potential for problems if third-party libraries use
struct timeval as part of their interface. This does not present
a problem for X and other "essential" system libraries.

group, passwd, hosts, networks, services, protocols, rpc, ethers,
shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
file controls what services are used for each individual database. This
works by loading shared libraries with names specified in `nsswitch.conf',
so service modules can be changed or added at any time without even
relinking any program. Currently there are the file, db, and NIS based
NSS services available.

* The new functions `strtoq' and `strtouq' parse integer values from
strings, like `strtol' and `strtoul', but they return `long long int' and
`unsigned long long int' values, respectively (64-bit quantities).
* The new functions `strtof' and `strtold' parse floating-point values from
strings, like `strtod', but they return `float' and `long double' values,
respectively (on some machines `double' and `long double' are the same).
* Ulrich Drepper has contributed new implementations of the floating-point
printing and reading code used in the `printf' family of functions and
`strtod', `strtof', and `strtold'. These new functions are perfectly
accurate, and much faster than the old ones.

* The `printf' and `scanf' families of functions now understand a new
formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
to group numbers as indicated by the locale; for `scanf' and friends, this
says to accept as valid only a number with all the proper grouping
separators in the right places. In the default "C" locale, numbers are
not grouped; but locales for specific countries will define the usual
conventions (i.e. separate thousands with `,' in the US locale).

* The pgrp functions have been regularized, slightly incompatibly but much
less confusingly. The core functions are now `getpgid' and `setpgid',
which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
argument) and BSD `setpgrp' (identical to `setpgid') functions are
provided for compatibility. There is no longer an incompatible `getpgrp'
with an argument declared under _BSD_SOURCE; no BSD code uses it.

operate on directory trees. This code comes from 4.4 BSD.

* An implementation of the NIS/YP(tm) based NSS service was contributed by
Thorsten Kukuk.
* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
completely POSIX compliant and also implemented the extended functionality
to handle alternate digit representation and alternate era date formats.
* Ulrich Drepper provided an implementation of the `strptime' function
defined in XPG4.2 which transforms a string into a `struct tm' value.
* Paul Eggert provided the tzselect shell script as part of the timezone
code. The shell script makes it easy to select the correct timezone
specification.
* The implementation of the malloc family of functions is completely replaced
by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
The implementation uses the mmap function (if available) and it is
optimized for the use in multi threaded programs.
* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
functions. This new functionality is usable by specifying a special
salt string and it is compatible with implementation on *BSD systems.
* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
`getsubopt' to handle second level command line options, `bsd_signal'
to access BSD style `signal' functionality, the obsolete `regexp' style
expression matcher.
* the `lchown' function is available on system which support this
functionality.
* The implementation of the shadow password handling function was contributed
by Ulrich Drepper.
* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
* POSIX.1g support was added. The <sys/select.h> header is available,
`isfdtype' and `pselect' are implemented. Craig Metz contributed an
implementation of `getaddrinfo'.

Version 1.09
* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
* The new function `daemon' from 4.4 BSD is useful for server programs that
want to put themselves in the background.
* Joel Sherrill has contributed support for several standalone boards that
run without an operating system.
* `printf', `scanf' and friends now accept a `q' type modifier for long
long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
* All of the code taken from BSD (notably most of the math and networking
routines) has been updated from the BSD 4.4-Lite release.
* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
* The new functions `getdomainname' and `setdomainname' fetch or change the
YP/NIS domain name. These are system calls which exist on systems which
have YP (aka NIS).
* The time zone data files have been updated for the latest international
conventions.
* The SunRPC programs `portmap' and `rpcinfo' are now installed in
$(sbindir) (usually /usr/local/sbin) instead of $(bindir).
Version 1.08
* The C library now includes support for Sun RPC, from Sun's free
RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
are included. (There is still no support for YP.)
* Tom Quinn has contributed a port of the C library to SGI machines running
Irix 4 (mips-sgi-irix4).
* The new `lockf' function is a simplified interface to the locking
facilities of `fcntl', included for compatibility.
* New time functions `timegm', `timelocal', and `dysize' for compatibility.
* New header file <sys/timeb.h> and new function `ftime' for compatibility.
* New header files <poll.h> and <sys/poll.h> and new function `poll' for
compatibility.
* The error message printed by `assert' for a failed assertion now includes
the name of the program (if using GNU ld) and the name of the calling
function (with versions of GCC that support this).
* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
* The library now includes the <sys/mman.h> header file and memory
management functions `mmap', `munmap', `mprotect', `msync', and
`madvise', on systems that support those facilities.
* The interface for `mcheck' has changed slightly: the function called to
abort the program when an allocation inconsistency is detected now takes
an argument that indicates the type of failure. The new function
`mprobe' lets you request a consistency check for a particular block at
any time (checks are normally done only when you call `free' or `realloc'
on a block).
* It is now possible to easily cross-compile the C library, building on one
system a library to run on another machine and/or operating system. All
you need to do is set the variable `HOST_CC' in `configparms' to the
native compiler for programs to run on the machine you are building on (a
few generator programs are used on Unix systems); set `CC' to the
cross-compiler.
* The new function `fexecve' (only implemented on the GNU system) executes
a program file given a file descriptor already open on the file.
Version 1.07
* Brendan Kehoe has contributed most of a port to the DEC Alpha
running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
* You can set the variable `libprefix' in `configparms' to specify a prefix
to be prepended to installed library files; this makes it easy to install
the GNU C library to be linked as `-lgnuc' or whatever.
* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
copies a limited number of characters from a string, and returns the
address of the last character written.
* You no longer need to check for whether the installed `stddef.h' is
compatible with the GNU C library. configure now checks for you.
* You can now define a per-stream `fileno' function to convert the
stream's cookie into an integral file descriptor.
* ``malloc (0)'' no longer returns a null pointer. Instead, it
allocates zero bytes of storage, and returns a unique pointer which
you can pass to `realloc' or `free'. The behavior is undefined if
you dereference this pointer.
* The C library now runs on Sony NEWS m68k machines running either
NewsOS 3 or NewsOS 4.
* The new `syscall' function is a system-dependent primitive function
for invoking system calls. It has the canonical behavior on Unix
systems, including unreliable return values for some calls (such as
`pipe', `fork' and `getppid').
* The error code `EWOULDBLOCK' is now obsolete; it is always defined
to `EAGAIN', which is the preferred name. On systems whose kernels
use two distinct codes, the C library now translates EWOULDBLOCK to
EAGAIN in every system call function.
Version 1.06
* The GNU C Library Reference Manual is now distributed with the library.
`make dvi' will produce a DVI file of the printed manual.
`make info' will produce Info files that you can read on line using C-h i
in Emacs or the `info' program.

pointer to a pointer--an object of type `void **').
* There is a new `printf' format: `%m' gives you the string corresponding
to the error code in `errno'.
* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
or `%[' conversion, but instead of filling in a fixed-sized buffer you
pass, the `a' modifier says to fill in a `char **' you pass with a
malloc'd string.
* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
`FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
* `mkstemp' is a traditional Unix function to atomically create and open a
uniquely-named temporary file.
Version 1.05
* The standard location for the file that says what the local timezone is
has changed again. It is now `/usr/local/etc/localtime' (or more
precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
* The distribution no longer contains any files with names longer than 14
characters.
* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
* New functions `ttyslot' and `syslog' from 4.4 BSD.
Version 1.04
* The configuration process has changed quite a bit. The `configure'
script is now used just like the configuration scripts for other GNU
packages. The `sysdeps' directory hierarchy is much rearranged.
The file `INSTALL' explains the new scheme in detail.
* The header files no longer need to be processed into ANSI C and
traditional C versions. There is just one set of files to install, and
it will work with ANSI or old C compilers (including `gcc -traditional').
* Brendan Kehoe and Ian Lance Taylor have ported the library to the
MIPS DECStation running Ultrix 4.
* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
Tom Quinn contributed the initial code. The GNU C library can NOT yet be
made itself into a shared library.
* Yet further improved support for the i386, running 4.3 BSD-like systems
(such as Mach 3 with the Unix single-server), or System V.
* New function `strncasecmp' to do case-insensitive string comparison
with limited length.
* New function `strsep' is a reentrant alternative to `strtok'.
* New functions `scandir' and `alphasort' for searching directories.
* New function `setenv' is a better interface to `putenv'.
* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
function for traversing a directory tree.
* The GNU obstack package is now also part of the C library.
The new function `open_obstack_stream' creates a stdio stream that
writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
formatted output directly to an obstack.
* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
* The new functions `strfry' and `memfrob' do mysterious and wonderful
things to your strings.
* There are some new test programs: test-fseek, testmb, and testrand.
* Some work has been done to begin porting the library to 4.4 BSD and Linux.
These ports are not finished, but are a good starting place for really
supporting those systems.
* `/etc/localtime' is now the standard location for the file that says what
the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
This follows the general principle that `/etc' is the place for all local
configuration files.
* The C library header files now use `extern "C"' when used by the C++
compiler, so the C library should now work with C++ code.
* The header file <bstring.h> is gone. <string.h> now declares bcopy,

* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
function which uses the `merge sort' algorithm, and is said to be
significantly faster than the old GNU `qsort' function. Merge sort is
now the standard `qsort' function. The new algorithm can require a lot
of temporary storage; so, the old sorting function is called when the
required storage is not available.
* The C library now includes Michael Glad's Ultra Fast Crypt, which
provides the Unix `crypt' function, plus some other entry points.
* The code and header files taken from 4.4 BSD have been updated with the
latest files released from Berkeley.

Update copyright dates not handled by scripts/update-copyrights. I've updated copyright dates in glibc for 2021. This is the patch for the changes not generated by scripts/update-copyrights and subsequent build / regeneration of generated files. As well as the usual annual updates, mainly dates in --version output (minus csu/version.c which previously had to be handled manually but is now successfully updated by update-copyrights), there is a small change to the copyright notice in NEWS which should let NEWS get updated automatically next year. Please remember to include 2021 in the dates for any new files added in future (which means updating any existing uncommitted patches you have that add new files to use the new copyright dates in them).
