|
|
|
|
2018-12-07 17:17:37 +00:00
|
|
|
|
* The getcpu wrapper function has been added, which returns the currently
|
|
|
|
|
|
used CPU and NUMA node. This function is Linux-specific.
|
|
|
|
|
|
|
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.

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.
(TLS_INIT_TP, TLS_DEFINE_INIT_TP): Remove tm_capable setup.
(THREAD_GET_TM_CAPABLE, THREAD_SET_TM_CAPABLE): Remove macros.
* sysdeps/powerpc/powerpc32/sysdep.h,
sysdeps/powerpc/powerpc64/sysdep.h (ABORT_TRANSACTION_IMPL,
ABORT_TRANSACTION): Remove macros.
* sysdeps/powerpc/sysdep.h (ABORT_TRANSACTION): Likewise.
* sysdeps/unix/sysv/linux/powerpc/elision-conf.c (elision_init): Set
__pthread_force_elision iff PPC_FEATURE2_HTM_NOSC is set.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h,
sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h
sysdeps/unix/sysv/linux/powerpc/syscall.S (ABORT_TRANSACTION): Remove
usage.
* sysdeps/unix/sysv/linux/powerpc/not-errno.h: Remove file.

|
|
|
|
* 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).
|
|
|
|
|
|
|
2018-12-07 14:00:04 +00:00
|
|
|
|
* The functions posix_spawn_file_actions_addchdir_np and
|
|
|
|
|
|
posix_spawn_file_actions_addfchdir_np have been added, enabling
|
|
|
|
|
|
posix_spawn and posix_spawnp to run the new process in a different
|
|
|
|
|
|
directory. These functions are GNU extensions. The function
|
|
|
|
|
|
posix_spawn_file_actions_addchdir_np is similar to the Solaris function
|
|
|
|
|
|
of the same name.

2018-09-12 13:32:05 +00:00
|
|
|
|
* The popen and system do not run atfork handlers anymore (BZ#17490).
|
|
|
|
|
|
Although it is a possible POSIX violation, the POSIX rationale in
|
|
|
|
|
|
pthread_atfork documentation regarding atfork handlers is to handle
|
2018-12-28 20:15:41 +00:00
|
|
|
|
inconsistent mutex state after a fork call in a multi-threaded process.
|
2018-09-12 13:32:05 +00:00
|
|
|
|
In both popen and system there is no direct access to user-defined mutexes.

|
|
2018-12-21 01:48:04 +00:00
|
|
|
|
* Support for the C-SKY ABIV2 running on Linux has been added. This port
|
|
|
|
|
|
requires at least binutils-2.32, gcc-9.0, and linux-4.20. Two ABIs are
|
|
|
|
|
|
supported:
|
|
|
|
|
|
- C-SKY ABIV2 soft-float little-endian
|
|
|
|
|
|
- C-SKY ABIV2 hard-float little-endian

|
|
|
|
* 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).
|
|
|
|
|
|
|
2019-01-24 14:04:12 +00:00
|
|
|
|
* As a GNU extension, the '_' and '-' flags can now be applied to
|
|
|
|
|
|
"%EY" to control how the year number is formatted; they have the
|
|
|
|
|
|
same effect that they would on "%Ey".

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.
[BZ #23649]
* sysdeps/unix/sysv/linux/microblaze/sys/procfs.h (struct
elf_prpsinfo): Use unsigned int for pr_uid and pr_gid.
* sysdeps/unix/sysv/linux/mips/sys/procfs.h (struct elf_prpsinfo):
Likewise.
* sysdeps/unix/sysv/linux/nios2/sys/procfs.h (struct
elf_prpsinfo): Likewise.
* sysdeps/unix/sysv/linux/riscv/sys/procfs.h (struct
elf_prpsinfo): Likewise.
* sysdeps/unix/sysv/linux/sys/procfs.h (struct elf_prpsinfo):
Likewise.
2018-09-14 13:21:33 +00:00
|
|
|
|
* 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.
|
|
|
|
|
|
|
2018-09-14 16:02:57 +00:00
|
|
|
|
* For the MIPS n32 ABI, the type of the pr_sigpend and pr_sighold members of
|
|
|
|
|
|
struct elf_prstatus, and the pr_flag member 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 those
|
|
|
|
|
|
structures.

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. Only use deprecated scanf when __USE_GNU is defined
and __STDC_VERSION__ is less than 199901L or __cplusplus is less
than 201103L, whichever is relevant for the language being compiled.
* libio/stdio.h, libio/bits/stdio-ldbl.h: Decide whether to redirect
scanf, fscanf, sscanf, vscanf, vfscanf, and vsscanf to their
__isoc99_ variants based only on __GLIBC_USE (DEPRECATED_SCANF).
* wcsmbs/wchar.h: wcsmbs/bits/wchar-ldbl.h: Likewise for
wscanf, fwscanf, swscanf, vwscanf, vfwscanf, and vswscanf.
* libio/iovsscanf.c
* libio/fwscanf.c
* libio/iovswscanf.c
* libio/swscanf.c
* libio/vscanf.c
* libio/vwscanf.c
* libio/wscanf.c
* stdio-common/fscanf.c
* stdio-common/scanf.c
* stdio-common/vfscanf.c
* stdio-common/vfwscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-compat.c
* sysdeps/ieee754/ldbl-opt/nldbl-fscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-fwscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-iovfscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-scanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-sscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-swscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-vfscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-vfwscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-vscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-vsscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-vswscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-vwscanf.c
* sysdeps/ieee754/ldbl-opt/nldbl-wscanf.c:
Override __GLIBC_USE_DEPRECATED_SCANF to 1.
* stdio-common/sscanf.c: Likewise. Remove ldbl_hidden_def for __sscanf.
* stdio-common/isoc99_sscanf.c: Add libc_hidden_def for __isoc99_sscanf.
* include/stdio.h: Provide libc_hidden_proto for __isoc99_sscanf,
not sscanf.
[!__GLIBC_USE (DEPRECATED_SCANF)]: Define sscanf as __isoc99_scanf
with a preprocessor macro.
* stdio-common/bug21.c, stdio-common/scanf14.c:
Use %ms instead of %as, %mS instead of %aS, %m[] instead of %a[];
remove DIAG_IGNORE_NEEDS_COMMENT for -Wformat.
* stdio-common/scanf16.c: Likewise. Add __attribute__ ((format (scanf)))
to xscanf, xfscanf, xsscanf.
* stdio-common/scanf14a.c: New copy of scanf14.c which still uses
%as, %aS, %a[]. Remove DIAG_IGNORE_NEEDS_COMMENT for -Wformat.
* stdio-common/scanf16a.c: New copy of scanf16.c which still uses
%as, %aS, %a[]. 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.

|
|
|
* 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, ...))).

|
|
|
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
|
2018-07-19 19:04:56 +00:00
|
|
|
|
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.
|

|
|
|
|
|
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.
|
|
|
|
|
|
|
2018-06-18 16:23:44 +00:00
|
|
|
|
* Unicode 11.0.0 Support: Character encoding, character type info, and
|
|
|
|
|
|
transliteration tables are all updated to Unicode 11.0.0, using
|
|
|
|
|
|
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. Tested with build-many-glibcs.py with both GCC 6 and GCC 7.

Add narrowing subtract functions.
This patch adds the narrowing subtract functions from TS 18661-1 to
glibc's libm: fsub, fsubl, dsubl, f32subf64, f32subf32x, f32xsubf64

f64subf128, f32xsubf64x, f32xsubf128, f64xsubf128 for configurations
with _Float64x and _Float128; __nldbl_dsubl for ldbl-opt.
The changes are essentially the same as for the narrowing add
functions, so the description of those generally applies to this patch
as well.

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.
The changes are mostly essentially the same as for the narrowing add
functions, so the description of those generally applies to this patch
as well. f32xmulf64 for i386 cannot use precision control as used for
add and subtract, because that would result in double rounding for
subnormal results, so that uses round-to-odd with long double
intermediate result instead. The soft-fp support involves adding a
new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs
and outputs.
Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft
float) and powerpc, and with build-many-glibcs.py.

* 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

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.

* 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.

* 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.

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.
[BZ #18471]
* sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Use weak
aliases for non-libc case of versioned symbols.
* sysdeps/unix/sysv/linux/lseek64.c: Include <shlib-compat.h>.
(llseek): Define as compat symbol if
[SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_28)], not as weak alias
with link warning.

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.

is added to fix some Linux Open File Description (OFD) locks usage on non

fcntl and LFS support is handled transparently. Also for Linux, the OFD

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.

|

* 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.

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. 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.

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. 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.

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.
Tested (a) for x86_64, (b) for aarch64, (c) with build-many-glibcs.py

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.
Tested for x86_64 and x86, and with build-many-glibcs.py, with both
GCC 6 and GCC 7.

2017-09-18 22:00:22 +00:00
|
|
|
|
* 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
|
2018-02-01 00:45:43 +00:00
|
|
|
|
same syntax as "mon" and "abmon". These arrays are optional; if they
|
|
|
|
|
|
are not provided then they have the same content as "mon" and "abmon",
|
|
|
|
|
|
respectively.
|
|
|
|
|
|
|
|
|
|
|
|
These features are provided for locales which define "alt_mon" and/or
|
|
|
|
|
|
"ab_alt_mon" in their locale source data. This release includes such
|
|
|
|
|
|
alternative month name data for the following languages: Belarusian,
|
|
|
|
|
|
Croatian, Greek, Lithuanian, Polish, Russian, and Ukrainian.
|
2017-09-18 22:00:22 +00:00

|
|

This feature is currently a GNU extension, but it is expected to
|
|
|
|
|
|
be added to the next revision of POSIX, and it is also already
|
|
|
|
|
|
available on some BSD-derived operating systems.

support for two grammatical forms of the month names, also extends the locale

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.

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.

<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. The calls in ns_print.c (part of incomplete
handling of TKEY) are changed to use %lu to print times instead of
trying to pretty-print the times any more.
Tested for x86_64.
* resolv/res_debug.c (p_secstodate): Condition definition on
[SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)]. Define
directly as __p_secstodate, and as a compat symbol. Do not use
libresolv_hidden_def.
* resolv/resolv.h (p_secstodate): Remove macro and function
declaration.
* resolv/ns_print.c (ns_sprintrrf): Print times with %lu, not
using p_secstodate.
* include/resolv.h (__p_secstodate): Do not use
libresolv_hidden_proto.
* resolv/Makefile (tests): Move tst-p_secstodate to ....
(tests-internal): ... here.
* resolv/tst-p_secstodate.c: Include <shlib-compat.h>. Condition
all contents on [TEST_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)]
and declare and use __p_secstodate and use compat_symbol_reference
in that case.
[!TEST_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)] (do_test): Add
implementation returning 77.

* The libresolv function p_secstodate is no longer supported for new
|
|
|
|
|
|
programs.

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.
The contents of (bits/)libio.h and (bits/)_G_config.h are still
exposed to external software via stdio.h; changing that requires more
complex surgery than I have time to attempt right now.
* libio/libio.h, libio/_G_config.h: New stub headers which issue a
deprecation warning and then include <bits/libio.h>, <bits/_G_config.h>
respectively.
* libio/libio.h: Rename the original version of this file to
libio/bits/libio.h. Error out if not included by stdio.h or the
stub libio.h.
* include/libio.h: Move to include/bits. Forward to libio/bits/libio.h.
* sysdeps/generic/_G_config.h: Move to top-level bits/. Error out
if not included by bits/libio.h or the stub _G_config.h.
* sysdeps/unix/sysv/linux/_G_config.h: Move to
sysdeps/unix/sysv/linux/bits. Error out if not included by
bits/libio.h or the stub _G_config.h.
* libio/stdio.h: Include bits/libio.h, not libio.h.
* libio/Makefile: Install bits/libio.h and bits/_G_config.h as
well as libio.h and _G_config.h.
* csu/init.c, libio/fmemopen.c, libio/iolibio.h, libio/oldfmemopen.c
* libio/strfile.h, stdio-common/vfscanf.c
* sysdeps/pthread/flockfile.c, sysdeps/pthread/funlockfile.c
Include stdio.h, not _G_config.h nor libio.h.
* libio/iofgetpos.c: Also rename fgetpos64 out of the way.
* libio/iofsetpos.c: Also rename fsetpos64 out of the way.
* scripts/check-installed-headers.sh: Skip libio.h and _G_config.h.
2017-12-23 05:06:03 +00:00
|
|
|
|
* The nonstandard header files <libio.h> and <_G_config.h> are deprecated
|
|
|
|
|
|
and will be removed in a future release. Software that is still using
|
|
|
|
|
|
either header should be updated to use standard <stdio.h> interfaces
|
|
|
|
|
|
instead.

2017-07-05 13:03:00 +00:00
|
|
|
|
Major new features:
|
|
|
|
|
|
|
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.
|
|

|
|
|
|
2017-05-31 09:10:25 +00:00
|
|
|
|
* Unicode 10.0.0 Support: Character encoding, character type info, and
|
|
|
|
|
|
transliteration tables are all updated to Unicode 10.0.0, using
|
2017-02-21 11:30:38 +00:00
|
|
|
|
generator scripts contributed by Mike FABIAN (Red Hat).
|
2017-07-26 06:15:01 +00:00
|
|
|
|
These updates cause user visible changes, especially the changes in
|
|
|
|
|
|
wcwidth for many emoji characters cause problems when emoji sequences
|
|
|
|
|
|
are rendered with pango, see for example:

|
|
|
|
|
2017-07-05 13:46:57 +00:00
|
|
|
|
- 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.
|
2017-04-21 13:40:56 +00:00
|
|
|
|
|
2017-07-05 13:46:57 +00:00
|
|
|
|
- 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.
|

|
|
|
|
|
2017-07-05 13:46:57 +00:00
|
|
|
|
- When the “rotate” (RES_ROTATE) resolver option is active, the GNU C
|
|
|
|
|
|
Library will now randomly pick a name server from the configuration as a
|
|
|
|
|
|
starting point. (Previously, the second name server was always used.)
|
2017-05-08 12:59:21 +00:00
|
|
|
|
|
2017-07-05 13:03:00 +00:00
|
|
|
|
* The tunables feature is now enabled by default. This allows users to tweak
|
|
|
|
|
|
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
|
2017-06-20 12:31:18 +00:00
|
|
|
|
|
2017-07-05 13:03:00 +00:00
|
|
|
|
* 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.

|
|
|
2017-07-05 13:03:00 +00:00
|
|
|
|
* 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.

* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
|
2017-07-05 17:43:58 +00:00
|
|
|
|
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
|
|
|
|
|
|
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
|
|

|
|
|
|
To compile programs that use this feature, the compiler must support
|
2017-07-05 17:43:58 +00:00
|
|
|
|
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.

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
|
|
|
|
|
|
removed.
|
|
|
|
|
|
|
|
|
|
|
|
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
|
2017-07-05 13:46:57 +00:00
|
|
|
|
will only be built and installed when the GNU C Library is configured with
|
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
|
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.
|
2017-06-30 08:43:33 +00:00
|
|
|
|
|
2017-06-30 09:31:41 +00:00
|
|
|
|
* The _res_opcodes variable has been removed from libresolv. It had been
|
|
|
|
|
|
exported by accident.
|
|
|
|
|
|
|
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.)
|
|
|
|
|
|
|
2017-07-05 13:46:57 +00:00
|
|
|
|
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
|
2017-07-05 13:03:00 +00:00
|
|
|
|
|
2017-07-05 13:46:57 +00:00
|
|
|
|
* On most architectures, GCC 4.9 or later is required to build the GNU C
|
|
|
|
|
|
Library. On powerpc64le, GCC 6.2 or later is required.
|
2017-07-05 13:03:00 +00:00
|
|
|
|
|
|
|
|
|
|
Older GCC versions and non-GNU compilers are still supported when
|
2017-07-05 13:46:57 +00:00
|
|
|
|
compiling programs that use the GNU C Library. (We do not know exactly
|
|
|
|
|
|
how old, and some GNU extensions to C may be _de facto_ required. If you
|
|
|
|
|
|
are interested in helping us make this statement less vague, please
|

Security related changes:
|
|
|
|
|
|
|
2017-04-13 11:09:38 +00:00
|
|
|
|
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
|
2017-08-02 02:37:16 +00:00
|
|
|
|
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
|
|
|
|
|
|
|
|
|
|
|
|
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
|
|
|
|
|
|
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
|
|
|
|
|
|
|
|
|
|
|
|
* Avoid printing a backtrace from the __stack_chk_fail function since it is
|
|
|
|
|
|
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
|
|
|
|
|
|
(CVE-2010-3192).
|
|
|
|
|
|
|
|
|
|
|
|
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
|
|
|
|
|
|
fixed (CVE-2017-12133).

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).

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.

* The inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated. This
|
|
|
|
|
|
means that in a future release, the macros “major”, “minor”, and “makedev”
|
|
|
|
|
|
will only be available from <sys/sysmacros.h>.
|
|
|
|
|
|
|
|
|
|
|
|
These macros are not part of POSIX nor XSI, and their names frequently
|
|
|
|
|
|
collide with user code; see for instance glibc bug 19239 and Red Hat bug
|
|
|
|
|
|
130601. <stdlib.h> includes <sys/types.h> under _GNU_SOURCE, and C++ code
|
|
|
|
|
|
presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the
|
|
|
|
|
|
problem.

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). Other architecture versions are untested.

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.
I believe we have consensus for adding TS 18661-1 interfaces as per
<https://sourceware.org/ml/libc-alpha/2016-06/msg00421.html>.

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).

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.)

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.

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.

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.

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.
Tested for x86_64, x86, mips64 and powerpc.

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.

* 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.

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.

* 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.

* 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

for the Linux quota interface which predates kernel version 2.4.22 has
|

been removed.

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.

* 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.

|
|
|
|
|
|
2017-01-14 11:07:41 +00:00

|
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.
|
|

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.

|
|
|
|
* 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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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

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.

* GDB pretty printers have been added for mutex and condition variable
|
|
|
|
|
|
structures in POSIX Threads. When installed and loaded in gdb these pretty
|
|
|
|
|
|
printers show various pthread variables in human-readable form when read
|
|
|
|
|
|
using the 'print' or 'display' commands in gdb.

|
|
|
|
* Tunables feature added to allow tweaking of the runtime for an application
|
|
|
|
|
|
program. This feature can be enabled with the '--enable-tunables' configure
|
|
|
|
|
|
flag. The GNU C Library manual has details on usage and README.tunables has
|
|
|
|
|
|
instructions on adding new tunables to the library.

|
|

2017-02-05 13:06:06 +00:00
|
|
|
|
* A new version of condition variables functions have been implemented in
|
|
|
|
|
|
the NPTL implementation of POSIX Threads to provide stronger ordering
|
|
|
|
|
|
guarantees.
|
|
|
|
|
|
|
|
|
|
|
|
* A new version of pthread_rwlock functions have been implemented to use a more
|
|
|
|
|
|
scalable algorithm primarily through not using a critical section anymore to
|
|
|
|
|
|
make state changes.

have been created with makecontext could fail to terminate due to a
|

missing .cantunwind annotation. This has been observed to lead to a hang
|

(denial of service) in some Go applications compiled with gccgo. Reported

* The DNS stub resolver functions would crash due to a NULL pointer
|
|
|
|
|
|
dereference when processing a query with a valid DNS question type which
|
|
|
|
|
|
was used internally in the implementation. The stub resolver now uses a
|
|
|
|
|
|
question type which is outside the range of valid question type values.

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.

* 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.

|
|
|
been included in previous releases.

|
|
|
|
|
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.

|
|
|
|
* 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

libm. They are defined by TS 18661 and IEEE754-2008. 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
|
|

* An unnecessary stack copy in _nss_dns_getnetbyname_r was removed. It
|
|
|
|
|
|
could result in a stack overflow when getnetbyname was called with an

* Previously, getaddrinfo copied large amounts of address data to the stack,
|
|
|
|
|
|
even after the fix for CVE-2013-4458 has been applied, potentially
|
|
|
|
|
|
resulting in a stack overflow. getaddrinfo now uses a heap allocation
|
|
|
|
|
|
instead. Reported by Michael Petlan. (CVE-2016-3706)

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.

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.

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).

for the form NAME@VERSION:OBSOLETED and generate SHLIB_COMPAT
conditionals for them.
* sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Likewise.

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.

* 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

* 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

* 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)

* 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.

* CVE-2014-8121 The NSS backends shared internal state between the getXXent
|
|
|
|
|
|
and getXXbyYY NSS calls for the same database, causing a denial-of-service

* Added vector math library named libmvec with the following vectorized x86_64
|
2015-06-18 17:11:27 +00:00
|
|
|
|
implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
|
|
|
|
|
|
pow, powf.
|
2015-06-09 11:25:49 +00:00
|
|
|
|
The library can be disabled with --disable-mathvec. Use of the functions is
|
|
|
|
|
|
enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
|
2015-06-25 16:46:50 +00:00
|
|
|
|
Shared library libmvec.so is linked in as needed when using -lm (no need to
|
|
|
|
|
|
specify -lmvec explicitly for not static builds).

compliance. The new implementation fixes the following long-standing
|
|
|
|
|
|
issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
|
|
|
|

* 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.

This header was formerly part of SUS, but was deprecated in 1994 and
|
2015-08-01 18:38:05 +00:00
|
|
|

* CVE-2015-1472 CVE-2015-1473 Under certain conditions wscanf can allocate
|
|
|
|
|
|
too little memory for the to-be-scanned arguments and overflow the
|
|
|
|

* 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.

|
* 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.

* 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.
(+gccwarn-c): Do not use -Werror=implicit-function-declaration.
* manual/install.texi (Configuring and compiling): Document
--disable-werror.
* INSTALL: Regenerated.
* debug/Makefile (CFLAGS-tst-chk1.c): Add -Wno-error.
(CFLAGS-tst-chk2.c): Likewise.
(CFLAGS-tst-chk3.c): Likewise.
(CFLAGS-tst-chk4.cc): Likewise.
(CFLAGS-tst-chk5.cc): Likewise.

2014-12-10 01:14:48 +00:00
|
|
|
|
* The GNU C Library is now built with -Werror by default. This can be
|
|
|
|
|
|
disabled by configuring with --disable-werror.
|
|
|
|
|
|
|
2014-12-01 10:31:29 +00:00

2014-11-14 18:52:16 +00:00
|
|
|
|
|
|
|
|
|
|
* The obsolete sigvec function has been removed. This was the original
|
|
|
|
|
|
4.2BSD interface that inspired the POSIX.1 sigaction interface, which
|
|
|
|
|
|
programs have been using instead for about 25 years. Of course, ABI
|
|
|
|
|
|
compatibility for old binaries using sigvec remains intact.

|
* 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.

* Reverted change of ABI data structures for s390 and s390x:
|
|
|
|
|
|
On s390 and s390x the size of struct ucontext and jmp_buf was increased in
|
|
|
|
|
|
2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions
|
|
|
|
|
|
of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp
|
|
|
|
|
|
are preserved pointing straight to the same implementation as the old ones.
|
2014-08-27 15:53:25 +00:00
|
|
|
|
Given that, new callers will simply provide a too-big buffer to these
|
2014-08-01 07:48:17 +00:00
|
|
|
|
functions. Any applications/libraries out there that embed jmp_buf or
|
|
|
|
|
|
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.

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.

|
* 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.

* 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.

* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
|
|
|
|
|
|
copy the path argument. This allowed programs to cause posix_spawn to
|
|
|
|
|
|
deference a dangling pointer, or use an unexpected pathname argument if
|
|
|
|
|
|
the string was modified after the posix_spawn_file_actions_addopen

invocation.

* All supported architectures now use the main glibc sysdeps directory
|

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

|
|
|
|
|
|
|
* The NPTL implementation of POSIX pthreads is no longer an "add-on".
|
|
|
|
|
|
On configurations that support it (all Linux configurations), it's now
|
|
|
|
|
|
used regardless of the --enable-add-ons switch to configure. It is no
|
|
|
|
|
|
longer possible to build such configurations without pthreads support.

* 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.

* 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.

* Support for loadable gconv transliteration modules has been removed.
|
|
|
|
|
|
The support for transliteration modules has been non-functional for
|
|
|
|
|
|
over a decade, and the removal is prompted by security defects. The
|
|
|
|
|
|
normal gconv conversion modules are still supported. Transliteration
|
|
|
|
|
|
with //TRANSLIT is still possible, and the //IGNORE specifier
|
2014-08-26 18:43:07 +00:00

support compiling programs that are derived from BSD sources and use
|
|

* 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.

|
|
2013-09-23 05:50:02 +00:00
|

|
|
* CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
|
|
|
|
|
|
rules for large collation sequences to optimize multiple passes and falls
|
|
|
|
|
|
back to alloca if malloc fails, resulting in a possible stack overflow.

|
|
The implementation now falls back to an uncached collation sequence lookup
|

if malloc fails.

initialized for static applications resulting in the security feature
|
|
|
|
|
|
being disabled. The pointer guard is now correctly initialized to a

2013-09-25 15:40:50 +00:00
|
|
|
|
* Substantially revised locales: gd_GB, ht_HT
|
|
|
|
|
|
|
2013-09-20 05:25:09 +00:00
|
|
|
|
* The LC_ADDRESS field was updated to support country_car for almost all
|
|
|
|
|
|
supported locales.

|
|
|
|
|
|
|
2013-09-24 22:07:47 +00:00
|
|
|
|
* The localedef utility now supports --big-endian and --little-endian
|
|
|
|
|
|
command-line options to generate locales for a different system from that
|
|
|
|
|
|
for which the C library was built.
|
|
|
|
|
|
|
2013-10-26 00:48:25 +00:00
|
|
|
|
* Binary locale files now only depend on the endianness of the system for
|
|
|
|
|
|
which they are generated and not on other properties of that system. As a
|
|
|
|
|
|
consequence, binary files generated with new localedef may be incompatible
|
|
|
|
|
|
with old versions of the GNU C Library, and binary files generated with
|
|
|
|
|
|
old localedef may be incompatible with this version of the GNU C Library,
|
|
|
|
|
|
in the following circumstances:
|
|
|
|
|
|
|
|
|
|
|
|
+ Locale files may be incompatible on m68k systems.
|
|
|
|
|
|
|
|
|
|
|
|
+ Locale archive files (but not separate files for individual locales) may
|
|
|
|
|
|
be incompatible on systems where plain "char" is signed.

|
|
|
|
2013-09-07 15:58:42 +00:00
|
|

|
|
|
|
--disable-versioning had not worked for several years.
|
|
|
|
|
|
|
2013-09-20 05:25:09 +00:00
|
|
|
|
* ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
|
|
|
|
|
|
cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).

* SystemTap probes for slow multiple precision fallback paths of
|
|
|
|
|
|
transcendental functions have been introduced.

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.
[_DEFAULT_SOURCE]: Undefine and redefine _DEFAULT_SOURCE,
_BSD_SOURCE and _SVID_SOURCE.
[!__STRICT_ANSI__ && !_ISOC99_SOURCE && !_POSIX_SOURCE &&
!_POSIX_C_SOURCE && !_XOPEN_SOURCE && !_BSD_SOURCE &&
!_SVID_SOURCE]: Likewise.
[_DEFAULT_SOURCE && !_POSIX_SOURCE && !_POSIX_C_SOURCE]
(__USE_POSIX_IMPLICITLY): Define.
[_DEFAULT_SOURCE && !_POSIX_SOURCE && !_POSIX_C_SOURCE]
(_POSIX_SOURCE): Undefine and redefine.
[_DEFAULT_SOURCE && !_POSIX_SOURCE && !_POSIX_C_SOURCE]
(_POSIX_C_SOURCE): Likewise.
* manual/creature.texi (_DEFAULT_SOURCE): Document.
(Feature Test Macros): Update documentation of default features.
2013-12-19 13:32:42 +00:00
|
|
|
|
* A new feature test macro _DEFAULT_SOURCE is available to enable the same
|
|
|
|
|
|
set of header declarations that are enabled by default, even when other
|
|
|
|
|
|
feature test macros or compiler options such as -std=c99 would otherwise
|
|
|
|
|
|
disable some of those declarations.
|
|
|
|
|
|
|
2013-12-17 18:05:42 +00:00
|
|
|
|
* The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
|
2013-12-17 18:11:48 +00:00
|
|
|
|
conflict with POSIX. The libbsd-compat library (which was a dummy library
|
|
|
|
|
|
that did nothing) has also been removed.
|
2014-01-29 07:20:37 +00:00
|
|
|
|
|
|
|
|
|
|
* Preliminary documentation about Multi-Thread, Async-Signal and
|
|
|
|
|
|
Async-Cancel Safety has been added.
|
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 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.

* CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
|
|
|
|
|
|
fixed (Bugzilla #15330).
|
2012-12-27 21:37:39 +00:00
|
|
|
|
|
2013-02-19 04:28:05 +00:00
|
|
|
|
* Add support for calling C++11 thread_local object destructors on thread
|
|
|
|
|
|
and program exit. This needs compiler support for offloading C++11
|
|
|
|
|
|
destructor calls to glibc.
|
|
|
|
|
|
|
2013-03-01 15:13:40 +00:00
|
|
|
|
* Improved worst case performance of libm functions with double inputs and
|
|
|
|
|
|
output.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for priority inherited mutexes in pthread condition variables on
|
|
|
|
|
|
non-x86 architectures.
|
|
|
|
|
|
|
2013-06-28 22:53:57 +00:00
|
|
|
|
* Port to Xilinx MicroBlaze contributed by David Holsgrove.
|
|
|
|
|
|
|
|
|
|
|
|
* Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
|
|
|
|
|
|
|
|
|
|
|
|
* Optimized string functions for ARM. Implemented by Will Newton and
|
|
|
|
|
|
Richard Henderson.
|
|
|
|
|
|
|
|
|
|
|
|
* Optimized libm functions for SPARC. Implemented by David S. Miller.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for building more of ARM glibc as Thumb-2 code. Implemented by
|
|
|
|
|
|
Richard Henderson.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for building most of MIPS glibc as MIPS16 code. Implemented by
|
|
|
|
|
|
Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
|
|
|
|
|
|
|
2013-03-15 07:00:03 +00:00
|
|
|
|
* Added a benchmark framework to track performance of functions in glibc.
|
|
|
|
|
|
|
2013-04-02 11:51:02 +00:00
|
|
|
|
* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
|
|
|
|
|
|
It is based on draft TS 18661 and currently enabled as a GNU extension.
|
2013-06-13 04:24:35 +00:00
|
|
|
|
|
2013-06-13 17:42:00 +00:00
|
|
|
|
* On Linux, the clock function now uses the clock_gettime system call
|
|
|
|
|
|
for improved precision, rather than old times system call.
|
2013-06-15 06:54:15 +00:00
|
|
|
|
|
2013-09-18 20:15:12 +00:00
|
|
|
|
* 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.
|
|
|
|
|
|
|
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.
|
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.
|
2013-07-25 15:49:13 +00:00
|
|
|
|
|
|
|
|
|
|
* Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10
|
|
|
|
|
|
availability). Implemented by Ryan S. Arnold.
|
|
|
|
|
|
|
|
|
|
|
|
* Support added for POWER8 platform. Implemented by Ryan S. Arnold.

|
|
|
2012-11-28 17:07:39 +00:00
|
|
|
|
* The add-on ports collection is now distributed in the "ports" subdirectory
|
|
|
|
|
|
of the main GNU C Library distribution, rather than separately.
|
|
|
|
|
|
|
2012-11-09 23:18:49 +00:00
|
|
|
|
* Port to ARM AArch64 contributed by Linaro.
|
|
|
|
|
|
|
2012-07-12 11:04:55 +00:00
|
|
|
|
* Support for STT_GNU_IFUNC symbols added for s390 and s390x.
|
|
|
|
|
|
Optimized versions of memcpy, memset, and memcmp added for System z10 and
|
|

2012-07-25 17:46:22 +00:00
|
|
|
|
* The new function secure_getenv allows secure access to the environment,
|
|
|
|
|
|
returning NULL if running in a SUID/SGID process. This function replaces
|
|
|
|
|
|
the internal function __secure_getenv.

|
|
|
|
|
|
2012-07-26 10:03:35 +00:00

|
|
|
|
|
Implemented by Maxim Kuvyrkov.

|
|
|
|
2012-08-03 13:42:47 +00:00

|
* The minimum Linux kernel version that this version of the GNU C Library
|
2012-08-07 16:40:32 +00:00
|
|
|
|
can be used with is 2.6.16.

|
|
|
2012-08-22 16:04:42 +00:00
|
|
|
|
* Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
|
|
|
|
|
|
powerpc POWER7. Implemented by Will Schmidt.
|
|
|
|
|
|
|
2012-08-22 20:31:12 +00:00
|
|
|
|
* New configure option --disable-nscd builds the C library such that it
|
|
|
|
|
|
never attempts to contact the Name Service Caching Daemon (nscd).
|
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.
|
2012-08-22 20:31:12 +00:00
|
|
|
|
|
2012-11-28 17:07:39 +00:00
|
|
|
|
* Improved support for cross-compilation, including cross-testing and
|
|
|
|
|
|
bootstrap builds without a previously built glibc.
|
|
|
|
|
|
|
2012-12-13 20:40:06 +00:00
|
|
|
|
* Several testsuite tests are now able to test multiple IFUNC variants of an
|
2012-12-13 20:42:06 +00:00
|
|
|
|
interface, rather than just testing the one that would be chooen by
|
2012-12-13 20:40:06 +00:00
|
|
|
|
default.
|
|
|
|
|
|
|
2012-11-28 17:07:39 +00:00
|
|
|
|
* New configure options --with-bugurl and --with-pkgversion, for
|
|
|
|
|
|
distributors to use to embed their bug-reporting and package version
|
|
|
|
|
|
information in --help and --version output.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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.

* Support for the x32 ABI on x86-64 added. The x32 target is selected by
|
|
|
|
|
|
configuring glibc with:
|
|
|
|
|
|
BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'

* ISO C11 support:
|
|
|
|
|
|
|
|
|
|
|
|
+ define static_assert
|
|
|
|
|
|
|

+ do not declare gets
|

|
|
|
|
|

|
|
+ declare at_quick_exit and quick_exit also for ISO C11
|
|
|
|
|
|
|
|
|
|
|
|
+ aligned_alloc. NB: The code is deliberately allows the size parameter
|
|
|
|
|
|
to not be a multiple of the alignment. This is a moronic requirement
|
|
|
|
|
|
in the standard but it is only a requirement on the caller, not the
|
|
|
|
|
|
implementation.

* New configure option --enable-obsolete-rpc makes the deprecated RPC
|
|
|
|
|
|
headers and functions available at compile time as they were before
|
|
|
|
|
|
version 2.14. This option will be removed at some time in the future
|
|
|
|
|
|
after the TI-RPC library becomes fully sufficient for the needs of
|
|
|
|
|
|
existing applications.

2012-05-25 19:19:30 +00:00
|
|
|
|
* Compatibility code for Linux kernel versions before 2.4 has been removed.
|
2012-05-14 14:11:02 +00:00
|
|
|
|
Note that glibc is not expected to work with any Linux kernel version
|
|
|
|
|
|
before 2.6.
|
2012-05-22 16:52:55 +00:00
|
|
|
|
|
2012-05-24 14:45:49 +00:00
|
|
|
|
* New header <sys/auxv.h> and function getauxval allowing easy access to
|
|
|
|
|
|
the AT_* key-value pairs passed from the Linux kernel. The header also
|
|
|
|
|
|
defines the HWCAP_* bits associated with the AT_HWCAP key.
|
|
|
|
|
|
|
2012-05-22 16:52:55 +00:00
|

2012-05-25 20:49:31 +00:00
|
|
|
|
|
|
|
|
|
|
* New configure option --enable-systemtap builds SystemTap static probes
|
|
|
|
|
|
into libc for setjmp and longjmp and into libpthread for various operations.
|
|
|
|
|
|
So far the setjmp/longjmp probes and some of the libpthread probes are
|
|
|
|
|
|
provided only for i*86 and x86_64.

|
* More optimized functions for SPARC. Implemented by David S. Miller.
|
|
|
|
|
|
|
|
|
|
|
|
* Improved support for cross-compilation, especially bootstrap builds
|
|
|
|
|
|
without a previously built glibc.
|
|
|
|
|
|
|
|
|
|
|
|
* Ports for the TILE-Gx and TILEPro families of processors. Contributed by
|
|
|
|
|
|
Chris Metcalf from Tilera.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for the old ARM ABI has been removed from ports. Only the EABI is
|
|
|
|
|
|
now supported for ARM processors.
|
|
|
|
|
|
|
|
|
|
|
|
* The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
|
|
|
|
|
|
as the name of the dynamic linker, to distinguish it from the
|
|
|
|
|
|
/lib/ld-linux.so.3 dynamic linker used for the base EABI.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for CRIS has been removed from ports.
|
2012-06-04 18:46:37 +00:00

|
|
|
|
|
|
|
|
* A new class of installed header has been documented for low-level
|
|
|
|
|
|
platform-specific functionality. PowerPC added the first instance with a
|
|
|
|
|
|
function to provide time base register access. Contributed by Tulio

* Math library bug fixes. A thorough audit of all open math library bugs was
|
|
|
|
|
|
conducted by Joseph Myers. Significant progress was made on many math

|
|
|
|
|
library bugs resulting in more accurate exceptions and function results.

* The RPC implementation in libc is obsoleted. Old programs keep working
|
|
|
|
|
|
but new programs cannot be linked with the routines in libc anymore.
|
|
|
|
|
|
Programs in need of RPC functionality must be linked against TI-RPC.
|
2011-05-30 16:31:25 +00:00
|
|
|
|
The TI-RPC implementation is IPv6 enabled and there are other benefits.
|
2011-05-05 11:39:34 +00:00
|
|
|
|
|
|

Visible changes of this change include (obviously) the inability to link
|
2011-05-06 11:47:33 +00:00
|
|
|
|
programs using RPC functions without referencing the TI-RPC library and the
|
|
|
|
|
|
removal of the RPC headers from the glibc headers.

* The malloc hook implementation is marked deprecated and will be removed
|
|
|
|
|
|
from the default implementation in the next version. The design never
|
|
|
|
|
|
worked ever since the introduction of threads. Even programs which do
|
|
|
|
|
|
not create threads themselves can use multiple threads created internally.

* New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
|
|
|
|
|
|
will not be used to fill in password fields in the passwd.byname replies.
|
|
|
|
|
|
Instead it is used to synthesize the shadow.byname table, should it be
|
|
|
|
|
|
missing. This is a useful mode in some installations involving Solaris.

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
|
|
|
|

|
|
|
|
|
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
|
|
|

|
|
|
|
|
|
'options single-request' in /etc/resolv.conf.

* It is now possible to install audit libraries for the dynamic linker using
|
|
|
|
|
|
LD_AUDIT. Implemented by Ulrich Drepper.
|
2005-07-03 04:43:32 +00:00

|
|
|
|
|
|
* The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
|
|
|
|
|
|
longer supported. The new NPTL implementation requires Linux 2.6 kernels.
|
|
|
|
|
|
For a libc and libpthread that works well on Linux 2.4 kernels, we
|
|
|
|
|
|
recommend using the stable 2.3 branch.

|
|
|
|
|
|
|

Version 2.3.4
|
|
|
|
|
|
|
|
|
|
|
|
* Support for RFC 3678. Real implementations exist only for Linux so far.
|
|
|
|
|
|
Implemented by Ulrich Drepper.
|
2004-09-17 08:44:34 +00:00
|
|
|
|
|
|
|
|
|
|
* nscd can now cache entries persistently. Expiring entries are reloaded.
|
|
|
|
|
|
For speedups the cache can be shared in memory with client processes.
|
|
|
|
|
|
Implemented by Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* nscd can now perform SELinux checks.
|
|
|
|
|
|
Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
|
|
|
|
|
|
|
2004-10-19 16:05:21 +00:00
|
|
|
|
* getaddrinfo queries are now cached. Canonical name lookup is performed
|
2004-09-17 08:44:34 +00:00
|
|
|
|
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
|
2004-10-19 16:05:21 +00:00
|
|
|
|
the process after showing an error message. Implemented by Ulrich Drepper.
|
2004-09-17 08:44:34 +00:00
|
|
|
|
|
|
|
|
|
|
* Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
|
2004-10-19 16:05:21 +00:00
|
|
|
|
lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* Namespaces in ld.so are implemented. DSOs can be loaded in separate
|
|
|
|
|
|
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.
|
2004-12-19 09:41:58 +00:00
|
|
|
|
Implemented by Jakub Jelinek and Ulrich Drepper.
|
|
|
|
|
|
|
|
|
|
|
|
* 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.

|
|
|
|
|
|
|
2003-03-15 23:16:22 +00:00
|
|
|
|
* New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
|
|
|
|
|
|
interrogate the dynamic linker, compatible with the Solaris interface.
|
|
|
|
|
|
|
2003-03-03 00:20:51 +00:00
|
|
|
|

|
|
|
|
|
|
implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.

|
2003-04-24 23:45:17 +00:00
|
|
|
|
Implemented by Thorsten Kukuk.
|
|
|
|

Version 2.3.2

|
|
|
|
|
|
2002-12-03 00:54:55 +00:00
|
|
|
|
* 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.

|
|
|
* The functions getresuid, getresgid, setresuid, and setresgid, which
|
|
|
|
|
|
have long been available on Linux, are now declared in <unistd.h>
|
|
|
|
|
|
and are now also available on the Hurd.
|
|
|
|
|
|
|
|
|
|
|
|
* ELF thread-local storage support (TLS) now works on x86-64.
|
2002-10-14 08:03:18 +00:00
|
|
|
|
|
|
|
|
|
|
* The new dynamic string token $LIB is expanded in shared library names.
|
|
|
|
|
|
This normally expands to lib, but on some 64-bit platforms to lib64 instead.

|
PowerPC machines with no FPU.
|

|
|
|
2002-11-05 08:43:05 +00:00

|
* The `btowc' function should work at least twice as fast due to
|
|
|
|
|
|
specialized callbacks in the iconv modules. Implemented by Bruno Haible.
|
2003-01-13 09:28:02 +00:00
|
|
|
|
|
|
|
|
|
|
* With approriate thread add-ons cancelable functions are now implemented
|
|
|
|
|
|
in libc.so as well. No need to call the function in libpthread. This
|
|
|
|
|
|
change allowed to finally disable the incorrect and expensive handling
|
|
|
|
|
|
of weak definition in ld.so.
|
|
|
|
|
|
|
|
|
|
|
|
* Yet more PLT entries in libc.so have been removed. We finally arrived
|
|
|
|
|
|
at the bare minimum. Startup times improved appropriately.
|
|
|
|
|
|
|
|
|
|
|
|
* Support for the new Linux/x86 system call interface was added. The
|
|
|
|
|
|
AT_SYSINFO auxiliary vector entry is recognized and handled.

|
|
charsets.
|
|
|
|
|
|
|
|

* The Hurd now uses the GNU libio implementation of stdio rather than the
|
|
|
|
|
|
old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
|
|
|
|
|

|
|
* The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
|
|
|
|
|
|
with the same behavior as the Linux system call of the same name.

* Lots of headers were cleaned up. Using the tool in the conform/ subdir
|
2001-01-31 07:42:03 +00:00
|
|
|
|
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.

* 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).

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.

|
|
|
* 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.
|
|
|
|
|
|
|
1997-02-15 04:31:36 +00:00
|
|
|
|
* An additional locale model to support C++ Standard Library locale
|
1997-02-19 04:43:53 +00:00
|
|
|
|
model and probably more was implemented by Ulrich Drepper.
|
1997-02-15 04:31:36 +00:00
|
|
|
|
|
1997-02-19 04:43:53 +00:00
|
|
|
|
* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
|
1997-02-15 04:31:36 +00:00
|
|
|
|
symbol level.
|
|
|
|
|
|
|
|
|
|
|
|
* Miles Bader provided the `argp' function family to support hierachical
|
|
|
|
|
|
command line argument parsing, layered on top of getopt.

|
Version 2.0.1
|
|
|
|
|
|
|
|
|
|
|
|
* fixed lots of header problems (especially Linux/GNU specific)
|
|
|
|
|
|
|
|
|
|
|
|
* dynamic loader preserves all registers
|
|
|
|
|
|
|
|
|
|
|
|
* Roland McGrath provided support for handling of auxiliary objects in
|
|
|
|
|
|
the ELF dynamic loader.
|
|
|
|
|
|
|
|
|
|
|
|
* support for parallel builds is improved
|
|
|
|
|

1996-06-22 21:14:17 +00:00
|
|
|
|
Version 2.0
|
1995-02-18 01:27:10 +00:00
|
|
|
|
|
1996-03-19 21:59:41 +00:00
|
|
|
|
* GNU extensions are no longer declared by default. To enable them you
|
|
|
|
|
|
must define the macro `_GNU_SOURCE' in your program or compile with
|
|
|
|
|
|
`-D_GNU_SOURCE'.
|
|
|
|
|
|
|
1995-02-18 01:27:10 +00:00
|
|
|
|
* The library has changed from using GNU ld symbol aliases to using weak
|
|
|
|
|
|
symbols where available. The ELF object file format supports weak
|
|
|
|
|
|
symbols; GNU ld also supports weak symbols in the a.out format. (There
|
|
|
|
|
|
is also now support for other GNU ld extensions in ELF. Use the
|
1995-02-21 06:17:59 +00:00
|
|
|
|
`--with-elf' option to configure to indicate you have ELF, and
|
|
|
|
|
|
`--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
|
1995-02-18 01:27:10 +00:00
|
|
|
|
of many files which contained only symbol aliases, reducing the size of
|
|
|
|
|
|
the source and the compiled library; many other files were renamed to
|
|
|
|
|
|
less cryptic names previously occupied by the symbol alias files.
|
1996-08-26 10:28:45 +00:00
|
|
|
|
There is a new header file <elf.h> for programs which operate on
|
|
|
|
|
|
files in the ELF format.
|
1995-03-21 07:58:50 +00:00
|
|
|
|
|
|
|
|
|
|
* Converted to Autoconf version 2, so `configure' has more options.
|
|
|
|
|
|
Run `configure --help' to see the details.
|
|
|
|
|
|
|
|
|
|
|
|
* The library can now be configured to build profiling, highly-optimized
|
1995-08-07 21:45:04 +00:00
|
|
|
|
(but undebuggable), and/or shared libraries (ELF with GNU ld only). The
|
|
|
|
|
|
`--enable-profile', `--enable-omitfp', and `--enable-shared' options to
|
|
|
|
|
|
`configure' enable building these extra libraries. The shared library is
|
|
|
|
|
|
built by default when using both ELF and GNU ld. When shared libraries
|
|
|
|
|
|
are enabled, the new library `-ldl' is available for arbitrary run-time
|
|
|
|
|
|
loading of shared objects; its interface is defined in <dlfcn.h>. The
|
|
|
|
|
|
new header file <link.h> gives access to the internals of the run-time
|
1997-01-26 05:33:35 +00:00
|
|
|
|
dynamic linker, `ld.so'. The shell script `ldd' is similar to the
|
|
|
|
|
|
application of same name on other systems and it provides information
|
|
|
|
|
|
about dynamically linked binaries.
|
1995-03-21 07:58:50 +00:00
|
|
|
|
|
1996-01-02 08:57:42 +00:00
|
|
|
|
* The C library now provides the run-time support code for profiling
|
|
|
|
|
|
executables compiled with `-pg'. Programs can control the profiling code
|
1996-03-19 21:59:41 +00:00
|
|
|
|
through the interface in <sys/gmon.h>. The `gmon.out' files written by
|
|
|
|
|
|
the GNU C library can be read only by GNU `gprof' (from GNU binutils);
|
|
|
|
|
|
the support for this file format was contributed by David Mosberger-Tang.
|
1996-01-02 08:57:42 +00:00
|
|
|
|
|
1996-03-05 21:41:30 +00:00
|
|
|
|
* The math code has been replaced with a math library based on fdlibm from
|
1997-01-26 05:33:35 +00:00
|
|
|
|
Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
|
|
|
|
|
|
Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
|
|
|
|
|
|
functions. The math functions now reside in a separate library, so
|
|
|
|
|
|
programs using them will need to use `-lm' their linking commands.
|
|
|
|
|
|
|
|
|
|
|
|
* John C. Bowman contributed optimized ix87 assembler inline functions.

|
|
|
|
* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
|
|
|
|
|
|
mechanism similar to that found in Solaris 2. This is now used for the
|
1997-01-26 05:33:35 +00:00
|
|
|
|
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.

Mon Jun 24 22:39:12 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/alpha/dl-machine.h (ELF_MACHINE_RUNTIME_TRAMPOLINE):
A .plt entry now loads the .rela.plt offset directly rather
than making us calculate it.
Sun Jun 23 15:24:05 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* time/Makefile ($(installed-localtime-file) rule): Do
$(make-target-directory) first.
* resolv.h: Fix wrapper for resolv/resolv.h.
* configure.in (ld --no-whole-archive check): Use AC_TRY_COMMAND.

Sat Jun 22 16:49:47 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* rpm/Makefile ($(config)): Make sure the word list in the for
loop is syntactically non-empty.
1996-06-25 08:56:57 +00:00
|
|
|
|
|
1995-03-21 07:58:50 +00:00
|
|
|
|
* 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.
|
|
|
|
|
|
|
1997-01-26 05:33:35 +00:00
|
|
|
|
* The implementation of the POSIX locale model was completely rewritten by
|
|
|
|
|
|
Ulrich Drepper. This includes the new programs `localedef' and `locale'
|
|
|
|
|
|
to compile the POSIX locale definition.
|
|
|
|
|
|
|
|
|
|
|
|
* The former dummy implementations of the strcoll and strxfrm function are
|
|
|
|
|
|
now replaced by fully functional code contributed by Ulrich Drepper. The
|
|
|
|
|
|
collation information comes from the POSIX locale definitions.
|
|
|
|
|
|
|
1995-03-21 07:58:50 +00:00
|
|
|
|
* The new header <langinfo.h> defines an interface for accessing
|
|
|
|
|
|
various locale-dependent data (using the locale chosen with `setlocale').
|
|
|
|
|
|
|
1996-03-05 21:41:30 +00:00
|
|
|
|
* Ulrich Drepper has contributed a new suite of functions for operation on
|
1997-01-26 05:33:35 +00:00
|
|
|
|
wide-character and multibyte-character strings, in <wchar.h>;
|
1996-03-29 01:04:20 +00:00
|
|
|
|
and classification and case conversion of wide characters, in <wctype.h>.
|
1997-01-26 05:33:35 +00:00
|
|
|
|
These new functions are conforming to the ISO C, Amendement 1 specification.
|
|
|
|
|
|
|
|
|
|
|
|
* There is now a second implementation of the standard I/O library available.
|
|
|
|
|
|
It comes from GNU libg++ as was written by Per Bothner, heavily modified
|
|
|
|
|
|
by Hongjiu Lu and made thread safe by Ulrich Drepper.
|
1996-03-05 21:41:30 +00:00
|
|
|
|
|
1996-01-02 08:57:42 +00:00
|
|
|
|
* You can now use positional parameter specifications in format strings
|
1995-03-21 07:58:50 +00:00
|
|
|
|
for the `printf' and `scanf' families of functions. For example,
|
|
|
|
|
|
`printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
|
|
|
|
|
|
``Number 6, Mr Jones''. This is mainly useful when providing different
|
1995-03-24 07:59:23 +00:00
|
|
|
|
format strings for different languages, whose grammars may dictate
|
|
|
|
|
|
different orderings of the values being printed. To support this
|
1995-03-21 07:58:50 +00:00
|
|
|
|
feature, the interface for `register_printf_handler' has changed; see
|
1995-03-24 07:59:23 +00:00
|
|
|
|
the header file <printf.h> for details.
|
1995-03-21 07:58:50 +00:00
|
|
|
|
|
|
|
|
|
|
* 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).
|
1995-02-18 01:27:10 +00:00
|
|
|
|
|
|
|
|
|
|
* 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.
|
|
|
|
|
|
|
|
|
|
|
|
* The new header file <fts.h> and suite of functions simplify programs that
|
|
|
|
|
|
operate on directory trees. This code comes from 4.4 BSD.
|
|
|
|
|
|
|
1997-01-26 05:33:35 +00:00
|
|
|
|
* The resolver code has been updated from the BIND 4.9.5-P1 release.
|
|
|
|
|
|
Parts of the code were heavily modified by Ulrich Drepper to fit in the
|
|
|
|
|
|
NSS scheme used in glibc.
|
1995-02-18 01:27:10 +00:00
|
|
|
|
|
|
|
|
|
|
* There is a new malloc debugging hook `__memalign_hook'.
|
|
|
|
|
|
|
|
|
|
|
|
* There are new typedefs `ushort' for `unsigned short int' and `uint' for
|
|
|
|
|
|
`unsigned int' in <sys/types.h>. These are for compatibility only and
|
|
|
|
|
|
their use is discouraged.
|
|
|
|
|
|
|
|
|
|
|
|
* The `-lmcheck' library to enable standard malloc debugging hooks is now
|
|
|
|
|
|
done differently, so that it works even without GNU ld.
|
1995-02-21 06:17:59 +00:00
|
|
|
|
|
1995-02-25 01:23:32 +00:00
|
|
|
|
* New function `euidaccess' checks allowed access to a file like `access',
|
|
|
|
|
|
but using the effective IDs instead of the real IDs.
|
1995-03-21 07:58:50 +00:00
|
|
|
|
|
|
|
|
|
|
* The time zone data files have been updated for the latest and greatest
|
|
|
|
|
|
local time conventions of the countries of the world.
|
|
|
|
|
|
|
|
|
|
|
|
* The new function `dirfd' extracts the file descriptor used by a DIR stream;
|
|
|
|
|
|
see <dirent.h>.
|
|
|
|
|
|
|
|
|
|
|
|
* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
|
|
|
|
|
|
for formatting floating-point numbers. They are provided only for
|
1997-01-26 05:33:35 +00:00
|
|
|
|
compatibility; new programs should use `sprintf' instead. There are
|
|
|
|
|
|
also equivalent function for the `long double' floating-point type and
|
|
|
|
|
|
all functions also exist in a reentrant form.
|
1995-03-27 10:24:00 +00:00
|
|
|
|
|
|
|
|
|
|
* The new auxiliary library `-lutil' from 4.4 BSD contains various
|
|
|
|
|
|
functions for maintaining the login-record files (primarily of use to
|
|
|
|
|
|
system programs such as `login'), and convenient functions for
|
|
|
|
|
|
allocating and initializing a pseudo-terminal (pty) device.
|
1995-09-27 02:50:10 +00:00
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed new support for System V style
|
|
|
|
|
|
shared memory and IPC on systems that support it.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed several miscellaneous new functions found
|
|
|
|
|
|
in System V: The `hsearch' family of functions provide an effective
|
|
|
|
|
|
implementation of hash tables; `a64l' and `l64a' provide a very simple
|
|
|
|
|
|
binary to ASCII mapping; `drand48' and friends provide a 48-bit random
|
|
|
|
|
|
number generator.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed new reentrant counterparts for the
|
|
|
|
|
|
`random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
|
|
|
|
|
|
|
|
|
|
|
|
* Ulrich Drepper has contributed new, highly-optimized versions of several
|
|
|
|
|
|
string functions for the i486/Pentium family of processors.
|
|
|
|
|
|
|
1996-01-02 08:57:42 +00:00
|
|
|
|
* Ulrich Drepper has updated the Linux-specific code, based largely
|
1995-09-27 02:50:10 +00:00
|
|
|
|
on work done in Hongjiu Lu's version of GNU libc for Linux.
|
1997-01-26 05:33:35 +00:00
|
|
|
|
The GNU library now supports Linux versions 2.0.10 and later,
|
|
|
|
|
|
using the ELF object file format (i[3456]86-*-linux).
|
1995-09-27 02:50:10 +00:00
|
|
|
|
|
1996-03-19 21:59:41 +00:00
|
|
|
|
* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
|
|
|
|
|
|
|
1997-01-26 05:33:35 +00:00
|
|
|
|
* David Mosberger-Tang and Richard Henderson have ported the C library
|
|
|
|
|
|
to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
|
|
|
|
|
|
dynamic linking support for ELF/Alpha.
|
|
|
|
|
|
|
|
|
|
|
|
* Richard Henderson contributed several Alpha optimized assembler function
|
|
|
|
|
|
for arithmetic and string handling.
|
1996-03-19 21:59:41 +00:00
|
|
|
|
|
1995-09-27 02:50:10 +00:00
|
|
|
|
* Ulrich Drepper has contributed a new set of message catalog functions to
|
1996-06-22 21:14:17 +00:00
|
|
|
|
support multiple languages using the <libintl.h> interface, for use with
|
|
|
|
|
|
his new package GNU gettext. Translation volunteers have contributed
|
|
|
|
|
|
catalogs of the library's messages in Spanish, German, and Korean.
|
|
|
|
|
|
|
|
|
|
|
|
* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
|
|
|
|
|
|
program and the `catgets' function for reading the catalog files it
|
|
|
|
|
|
creates. (The <libintl.h> interface is preferred; we include the
|
|
|
|
|
|
<nl_types.h> interface using `catgets' only for source compatibility with
|
|
|
|
|
|
programs already written to use it.)
|
1996-01-02 08:57:42 +00:00
|
|
|
|
|
|
|
|
|
|
* New header file <values.h> gives SVID-compatible names for <limits.h>
|
|
|
|
|
|
constants.
|
|
|
|
|
|
|
|
|
|
|
|
* Various new macros, declarations, and small header files for compatibility
|
|
|
|
|
|
with 4.4 BSD.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `group_member' is a convenient way to check if a process has
|
|
|
|
|
|
a given effective group ID.
|
|
|
|
|
|
|
|
|
|
|
|
* When using GCC 2.7 and later, the socket functions are now declared in a
|
|
|
|
|
|
special way so that passing an argument of type `struct sockaddr_in *',
|
|
|
|
|
|
`struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
|
|
|
|
|
|
`struct sockaddr *' type, does not generate a type-clash warning.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `error' declared in header file <error.h> is a convenient
|
1996-12-20 01:39:50 +00:00
|
|
|
|
function for printing error messages and optionally exiting; this is the
|
1996-01-02 08:57:42 +00:00
|
|
|
|
canonical function used in GNU programs. The new functions `err', `warn',
|
|
|
|
|
|
and friends in header file <err.h> are the canonical 4.4 BSD interface for
|
|
|
|
|
|
doing the same thing.
|
|
|
|
|
|
|
|
|
|
|
|
* The <glob.h> interface has several new flags from 4.4 BSD that extend the
|
|
|
|
|
|
POSIX.2 `glob' function to do ~ and {...} expansion.
|
|
|
|
|
|
|
|
|
|
|
|
* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
|
1997-01-26 05:33:35 +00:00
|
|
|
|
`clearenv' which is used in POSIX.9 is also available.
|
1996-01-02 08:57:42 +00:00
|
|
|
|
|
|
|
|
|
|
* New function `getsid' returns session ID number on systems that support it.
|
|
|
|
|
|
|
1996-03-05 21:41:30 +00:00
|
|
|
|
* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
|
|
|
|
|
|
files <db.h> and <mpool.h> provide a rich set of functions for several
|
|
|
|
|
|
types of simple databases stored in memory and in files, and <ndbm.h> is
|
1996-12-20 01:39:50 +00:00
|
|
|
|
an old `ndbm'-compatible interface using the `db' functions. Link with
|
1996-07-08 17:45:03 +00:00
|
|
|
|
`-ldb' to get these functions.
|
1996-03-05 21:41:30 +00:00
|
|
|
|
|
|
|
|
|
|
* New macro `strdupa' copies a string like `strdup', but uses local stack
|
|
|
|
|
|
space from `alloca' instead of dynamic heap space from `malloc'.
|
1996-03-14 11:20:03 +00:00
|
|
|
|
|
|
|
|
|
|
* New function `strnlen' is like `strlen' but searches only a given maximum
|
1997-01-26 05:33:35 +00:00
|
|
|
|
number of characters for the null terminator. `stpncpy', `strndup' and
|
|
|
|
|
|
`strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
|
|
|
|
|
|
function.
|
1996-06-22 21:14:17 +00:00
|
|
|
|
|
|
|
|
|
|
* New function `statfs' in header <sys/statfs.h>.
|
|
|
|
|
|
|
|
|
|
|
|
* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
|
|
|
|
|
|
provide convenient functions for operating on blocks of null-terminated
|
|
|
|
|
|
strings.
|
|
|
|
|
|
|
|
|
|
|
|
* A new suite of functions in <utmp.h> handle all the details of reading
|
|
|
|
|
|
and writing the utmp file.
|
1997-01-26 05:33:35 +00:00
|
|
|
|
|
|
|
|
|
|
* 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.

|
1995-02-18 01:27:10 +00:00
|
|
|
|
|
|
|
|
|
|
* The library now supports SVR4 on i386s (i386-unknown-sysv4).
|
|
|
|
|
|
|
|
|
|
|
|
* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
|
|
|
|
|
|
|
|
|
|
|
|
* Jason Merrill has contributed a port to the Sequent Symmetry running
|
|
|
|
|
|
Dynix version 3 (i386-sequent-dynix).
|
|
|
|
|
|
|
|
|
|
|
|
* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
|
|
|
|
|
|
ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
|
|
|
|
|
|
|
|
|
|
|
|
* New function `memory_warnings' lets you arrange to get warnings when
|
|
|
|
|
|
malloc is running out of memory to allocate, like Emacs gives you.
|
|
|
|
|
|
|
|
|
|
|
|
* The C library now contains the relocating allocator used in Emacs 19 for
|
|
|
|
|
|
its editing buffers. This allocator (ralloc) minimizes allocation
|
|
|
|
|
|
overhead and fragmentation by moving allocated regions around whenever it
|
|
|
|
|
|
needs to. You always refer to a ralloc'd region with a "handle" (a
|
|
|
|
|
|
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,
|
Update.
2000-08-11 Ulrich Drepper <drepper@redhat.com>
* rt/aio_cancel.c: If canceling a specific request which is running
*really* do nothing.
* rt/aio_misc.h: Add `done' to states of a request.
* rt/aio_misc.c: Add several tests for the correct state.

in <strings.h>.)

|
* 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.
