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

alpha: Remove anonymous union in struct stat [BZ #27042]
This is clever, but it confuses downstream detection in at least zstd and GNOME's glib. zstd has preprocessor tests for the 'st_mtime' macro, which is not provided by the path using the anonymous union; glib checks for the presence of 'st_mtimensec' in struct stat but then tries to access that field in struct statx (which might be a bug on its own). Checked with a build for alpha-linux-gnu. |

linux: Consolidate brk implementation
It removes all the arch-specific assembly implementation. The outliers are alpha, where its kernel ABI explict return -ENOMEM in case of failure; and i686, where it can't use "call *%gs:SYSINFO_OFFSET" during statup in static PIE. Also some ABIs exports an additional ___brk_addr symbol and to handle it an internal HAVE_INTERNAL_BRK_ADDR_SYMBOL is added. Checked on x86_64-linux-gnu, i686-linux-gnu, adn with builsd for the affected ABIs. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com> |

linux: Disentangle fstatat from fxstatat
It implements all the required syscall for the all Linux kABIS on fstatat{64} instead of calling fxstatat{64}. On non-LFS implementation, it handles 3 cases: 1. New kABIs which uses generic pre 64-bit time Linux ABI (csky and nios): it issues __NR_fstat64 plus handle the overflow on st_ino, st_size, or st_blocks. 2. Old KABIs with old non-LFS support (arm, i386, hppa, m68k, microblaze, mips32, s390, sh, powerpc, and sparc32): it issues __NR_fstatat64 and convert the result to struct stat. 3. 64-bit kABI outliers (mips64 and mips64-n32): it issues __NR_newfstatat and convert the result to struct stat. The generic LFS implementation handles multiple cases: 1. XSTAT_IS_XSTAT64 being 1: 1.1. 64-bit kABI (aarch64, ia64, powerpc64*, s390x, riscv64, and x86_64): it issues __NR_newfstatat. 1.2. 64-bit kABI outlier (alpha): it issues __NR_fstatat64. 1.3. 64-bit kABI outlier where struct stat64 does not match kernel one (sparc64): it issues __NR_fstatat64 and convert the result to struct stat64. 1.4. 32-bit kABI with default 64-bit time_t (arc, riscv32): it issues __NR_statx and convert the result to struct stat64. 2.

The variable is placed in libc.so, and it can be true only in an outer libc, not libcs loaded via dlmopen or static dlopen. Since thread creation from inner namespaces does not work, pthread_create can update __libc_single_threaded directly.

New exp10f version without SVID compat wrapper
This patch changes the exp10f error handling semantics to only set errno according to POSIX rules. New symbol version is introduced at GLIBC_2.32. The old wrappers are kept for compat symbols. There are some outliers that need special handling: - ia64 provides an optimized implementation of exp10f that uses ia64 specific routines to set SVID compatibility. The new symbol version is aliased to the exp10f one. - m68k also provides an optimized implementation, and the new version uses it instead of the sysdeps/ieee754/flt32 one. - riscv and csky uses the generic template implementation that does not provide SVID support. For both cases a new exp10f version is not added, but rather the symbols version of the generic sysdeps/ieee754/flt32 is adjusted instead. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu. |

y2038: Replace __clock_gettime with __clock_gettime64
The __clock_gettime internal function is not supporting 64 bit time on architectures with __WORDSIZE == 32 and __TIMESIZE != 64 (like e.g. ARM 32 bit). The __clock_gettime64 function shall be used instead in the glibc itself as it supports 64 bit time on those systems. This patch does not bring any changes to systems with __WORDSIZE == 64 as for them the __clock_gettime64 is aliased to __clock_gettime (in ./include/time.h). |

semaphore: consolidate arch headers into a generic one
This consolidates the copy-pasted arch specific semaphore header into single version (based on s390) which suffices 32-bit and and 64-bit arch/ABI based on the canonical WORDSIZE.

sysv: Define __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64
On y2038 safe 32-bit systems the Linux kernel expects itimerval and rusage to use a 32-bit time_t, even though the other time_t's are 64-bit. There are currently no plans to make 64-bit time_t versions of these structs. There are also other occurrences where the time passed to the kernel via timeval doesn't match the wordsize. To handle these cases let's define a new macro __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64. This macro specifies if the kernel's old_timeval matches the new timeval64. This should be 1 for 64-bit architectures except for Alpha's osf syscalls. The define should be 0 for 32-bit architectures and Alpha's osf syscalls.

ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]
Exporting functions and relying on symbol interposition from libc.so
makes the choice of implementation dependent on DT_NEEDED order, which
is not what some compiler drivers expect.
This commit replaces one magic mechanism (symbol interposition) with
another one (preprocessor-/compiler-based redirection). This makes
the hand-over from the minimal malloc to the full malloc more
explicit.
Removing the ABI symbols is backwards-compatible because libc.so is
always in scope, and the dynamic loader will find the malloc-related
symbols there since commit

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

Linux: Add tables with system call numbers
The new tables are currently only used for consistency checks with the installed kernel headers and the architecture-independent system call names table. They are based on Linux 5.4. The goal is to use these architecture-specific tables to ensure that system call wrappers are available irrespective of the version of the installed kernel headers. The tables are formatted in the form of C header files so that they can be used directly in an #include directive, without external preprocessing. (External preprocessing of a plain table file would introduce cross-subdirectory dependency issues.) However, the intent is that they can still be treated as tables and can be processed by simple tools. The irregular system call names on 32-bit arm add a complication. The <fixup-asm-unistd.h> header is introduced to work around that, and the system calls are listed under regular names in the <arch-syscall.h> file. A make target, update-syscalls-list, is added to patch the glibc sources with data from the current kernel headers. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org> |

Use clock_gettime to implement gettimeofday.
Consolidate generic gettimeofday implementation to use clock_gettime. Linux ports that still provide gettimeofday through vDSO are not changed. Remove sysdeps/unix/clock_gettime.c, which implemented clock_gettime using gettimeofday; new OS ports must provide a real implementation of clock_gettime. Rename sysdeps/mach/gettimeofday.c to sysdeps/mach/clock_gettime.c and convert into an implementation of clock_gettime. It only supports CLOCK_REALTIME; Mach does not appear to have any support for monotonic clocks. It uses __host_get_time, which provides at best microsecond resolution. Hurd is currently using sysdeps/posix/clock_getres.c for clock_getres; its output for CLOCK_REALTIME is based on sysconf (_SC_CLK_TCK), and I do not know whether that gives the correct result. Unlike settimeofday, there are no known uses of gettimeofday's vestigial "get time zone" feature that are not bugs. (The per-process timezone support in localtime and friends is unrelated, and the programs that set the kernel's offset between the hardware clock and UTC do not need to read it back.) Therefore, this feature is dummied out. Henceforth, if gettimeofday's "struct timezone" argument is not NULL, it will write zeroes to both fields. Any program that is actually looking at this data will thus think it is running in UTC, which is probably more correct than whatever it was doing before. [__]gettimeofday no longer has any internal callers, so we can now remove its internal prototype and PLT bypass aliases. The __gettimeofday@GLIBC_2.0 export remains, in case it is used by any third-party code. It also allows to simplify the arch-specific implementation on x86 and powerpc to remove the hack to disable the internal route to non iFUNC variant for internal symbol. This patch also fixes a missing optimization on aarch64, powerpc, and x86 where the code used on static build do not use the vDSO.

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

Linux/Alpha: don't use timeval32 system calls.
Linux/Alpha has two versions of several system call wrappers that take or return data of type "struct timeval" (possibly nested inside a larger structure). The GLIBC_2.0 version is a compat symbol that calls __NR_osf_foo or __NR_old_foo and uses a struct timeval with a 32-bit tv_sec field. The GLIBC_2.1 version is used for current code, calls __NR_foo, and uses a struct timeval with a 64-bit tv_sec field. This patch changes all of the compat symbols of this type to be wrappers around their GLIBC_2.1 counterparts; the compatibility system calls will no longer be used. It serves as a proposal for part of how we do the transition to 64-bit time_t on systems that currently use 32-bit time_t: * The patched glibc will NOT use system calls that involve 32-bit time_t to implement its compatibility symbols. This will make both our lives and the kernel maintainers' lives easier. The primary argument I've seen against it is that the kernel could warn about uses of the old system calls, helping people find old binaries that need to be recompiled. I think there are several other ways we could accomplish this, e.g. scripts to scan the filesystem for binaries with references to the old symbol versions, or issuing diagnostics ourselves. * The compat symbols do NOT report failure after the Y2038 deadline. An earlier revision of this patch had them return -1 and set errno to EOVERFLOW, but Adhemerval pointed out that many of them have already performed side effects at the point where we discover the overflow, so that would break more than it fixes. Also, we don't want people to be _checking_ for EOVERFLOW from these functions; we want them to recompile with 64-bit time_t. So it's not actually useful for them to report failure to the calling code. * What they do do, when they encounter overflow, is saturate the overflowed "struct timeval"(s): tv_sec is set to INT32_MAX and tv_nsec is set to 999999. That means time stops advancing for programs with 32-bit time_t when they reach the deadline. That's obviously going to break stuff, but I think wrapping around is probably going to break _more_ stuff. I'd be interested to hear arguments against, if anyone has one. The new header file tv32-compat.h is currently Alpha-specific but I mean for it to be reused to aid in writing wrappers for all affected architectures. I only put it in sysdeps/unix/sysv/linux/alpha for now because I haven't checked whether the various "foo32" structures it defines agree with the ABI for ports other than Linux/Alpha.

ipc: Refactor sysvipc internal definitions
This patch refactor the internal sysvipc in two main points: 1. Add a new __ASSUME_SYSVIPC_DEFAULT_IPC_64 to infer the __IPC_64 value to be used along either the multiplexed __NR_ipc or wired-up syscall. The defaut value assumed for __IPC_64 is also changed from 0x100 to 0x0, aligning with Linux generic UAPI. The idea is to simplify the Linux 5.1 wire-up for sysvipc syscalls for some 32-bit ABIs (which expectes __IPC_64 being 0x0) and simplify new ports (which will no longer need to add ipc_priv.h). 2. It also removes some duplicated internal definition used on compat sysvipc symbols defined at ipc_priv.h (more specifically the __old_ipc_perm, SEMCTL_ARG_ADDRESS, MSGRCV_ARGS, and SEMTIMEDOP_IPC_ARGS).

The generic implementation follow the kernel ipc64_perm size so the syscall can be made directly without temporary buffer copy. However, since glibc defines the MODE field as mode_t, it omits the __PAD1 field (since glibc does not export mode_t as 16-bit for any architecture). It is a two-fold improvement: 2.1. New implementation which follow Linux UAPI will not need to provide an arch-specific ipc-perm.h header neither wrongly use the wrong 16-bit definition from previous default ipc.h (as csky did). 2.1. It allows consolidate ipc_perm definition for architectures that already provide mode_t as 32-bit. 3. All kernel ABIs for the supported architectures already provides the expected padding for mode type extension to 32-bit. However, some architectures the padding has the wrong placement, so it requires the ipc control routines (msgctl, semctl, and shmctl) to adjust the mode field accordingly. Currently they are armeb, microblaze, m68k, s390, and sheb. A new assume is added, __ASSUME_SYSVIPC_BROKEN_MODE_T, which the required ABIs define. 4. For the ABIs that define __ASSUME_SYSVIPC_BROKEN_MODE_T, it also require compat symbols that do not adjust the mode field. Checked on arm-linux-gnueabihf, aarch64-linux-gnu, powerpc64le-linux-gnu, and x86_64-linux-gnu. I also checked the sysvipc tests on hppa-linux-gnu, sh4-linux-gnu, s390x-linux-gnu, and s390-linux-gnu. I also did a sanity test against armeb qemu usermode for the sysvipc tests.

alpha: force old OSF1 syscalls for getegid, geteuid and getppid [BZ #24986]
On alpha, Linux kernel 5.1 added the standard getegid, geteuid and getppid syscalls (commit ecf7e0a4ad15287). Up to now alpha was using the corresponding OSF1 syscalls through: - sysdeps/unix/alpha/getegid.S - sysdeps/unix/alpha/geteuid.S - sysdeps/unix/alpha/getppid.S When building against kernel headers >= 5.1, the glibc now use the new syscalls through sysdeps/unix/sysv/linux/syscalls.list. When it is then used with an older kernel, the corresponding 3 functions fail. A quick fix is to move the OSF1 wrappers under the sysdeps/unix/sysv/linux/alpha directory so they override the standard linux ones. A better fix would be to try the new syscalls and fallback to the old OSF1 in case the new ones fail. This can be implemented in a later commit.

Finish move of clock_* functions to libc. [BZ #24959]
In glibc 2.17, the functions clock_getcpuclockid, clock_getres, clock_gettime, clock_nanosleep, and clock_settime were moved from librt.so to libc.so, leaving compatibility stubs behind. Now that the dynamic linker no longer insists on finding versioned symbols in the same library that originally defined them, we do not need the stubs anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases for most of the functions anymore either. (clock_gettime still needs one.) For ports added before 2.17, libc.so needs to provide two symbol versions for each, the default at GLIBC_2.17 plus a compat version matching what librt had. While I'm at it, move the clock_*.c files and their tests from rt/ to time/. |

Refactor sigcontextinfo.h
This patch refactor sigcontextinfo.h header to use SA_SIGINFO as default for both gmon and debug implementations. This allows simplify profil-counter.h on Linux to use a single implementation and remove the requirements for newer ports to redefine __sigaction/sigaction to use SA_SIGINFO. The GET_PC macro is also replaced with a function sigcontext_get_pc that returns an uintptr_t instead of a void pointer. It allows easier convertion to integer on ILP32 architecture, such as x32, without the need to suppress compiler warnings. The patch also requires some refactor of register-dump.h file for some architectures (to reflect it is now called from a sa_sigaction instead of sa_handler signal context). - Alpha, i386, and s390 are straighfoward to take in consideration the new argument type. - ia64 takes in consideration the kernel pass a struct sigcontextt as third argument for sa_sigaction. - sparc take in consideration the kernel pass a pt_regs struct as third argument for sa_sigaction. - m68k dummy function is removed and the FP state is dumped on register_dump itself. - For SH the register-dump.h file is consolidate on a common implementation and the floating-point state is checked based on ownedfp field. The register_dump does not change its output format in any affected architecture. I checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, powerpc64-linux-gnu, and powerpc64le-linux-gnu. I also checked the libSegFault.so through catchsegv on alpha-linux-gnu, m68k-linux-gnu and sh4-linux-gnu to confirm the output has not changed.

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

Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532]
The kernel changes for a 64-bit time_t on 32-bit architectures resulted in <asm/socket.h> indirectly including <linux/posix_types.h>. The latter is not namespace-clean for the POSIX version of <sys/socket.h>. This issue has persisted across several Linux releases, so this commit creates our own copy of the SO_* definitions for !__USE_MISC mode. The new test socket/tst-socket-consts ensures that the copy is consistent with the kernel definitions (which vary across architectures). The test is tricky to get right because CPPFLAGS includes include/libc-symbols.h, which in turn defines _GNU_SOURCE unconditionally. Tested with build-many-glibcs.py. I verified that a discrepancy in the definitions actually results in a failure of the socket/tst-socket-consts test. |

This patch fixes further coding style issues where code should have broken lines before operators in accordance with the GNU Coding Standards but instead was breaking lines after them.

ldbl-opt: Add error and error_at_line (bug 23984)
On platforms where long double may have the same format as double (-mlong-double-64), error and error_at_line do not take that into account and might produce wrong output if a long double conversion is requested by the format string ('%Lf'). This patch adds compatibility functions for this situation and redirects calls via header magic. Tested for powerpc, powerpc64 and powerpc64le. |

ldbl-opt: Add err, errx, verr, verrx, warn, warnx, vwarn, and vwarnx (bug 23984)
When support for long double format with 128-bits (-mlong-double-128) was added for platforms where long double had the same format as double, such as powerpc, compatibility versions for the functions listed in the commit title were missed. Since the older format of long double can still be used (with -mlong-double-64), using these functions with a format string that requests the printing of long double variables will produce wrong outputs. This patch adds the missing compatibility functions and header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le. |

ldbl-opt: Add argp_error and argp_failure (bug 23983)
The functions argp_error and argp_failure are missing support for printing long double values when long double has the same format as double. This patch adds the new functions __nldbl_argp_error and __nldbl_argp_failure, as well as header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le. |

alpha: Use Linux generic sigaction implementation
Alpha rt_sigaction syscall uses a slight different kernel ABI than generic one: arch/alpha/kernel/signal.c 90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act, 91 struct sigaction __user *, oact, 92 size_t, sigsetsize, void __user *, restorer) Similar as sparc, the syscall expects a restorer function. However different than sparc, alpha defines the restorer as the 5th argument (sparc defines as the 4th). This patch removes the arch-specific alpha sigaction implementation, adapt the Linux generic one to different restore placements (through STUB macro), and make alpha use the Linux generic kernel_sigaction definition.

Remove __ASSUME_ST_INO_64_BIT.
kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment "However, SH is lame, and still does not have a 64-bit inode field.". The macro is, in fact, defined to 0 by Alpha as well as SH. The Alpha case is, however, trivially useless: none of the files that test __ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel support for stat64 syscalls, with a 64-bit st_ino field, in Linux 2.6.4; the define to 0 for Alpha in glibc predates that). The SH kernel gained support for a 64-bit st_ino in struct stat64 in commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64() syscall."), which is in Linux 2.6.22 and later. So the redefinition of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of the files testing it do so immediately after a stat64-family syscall has been used, which will always have set the 64-bit st_ino correctly (in addition to the 32-bit __st_ino), while the relevant code __xstat32_conv executes only after such a syscall in the function calling __xstat32_conv. Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it. Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases around it identical, so that conditional is also removed. Tested compilation with build-many-glibcs.py for its Alpha and SH configurations; also ran the glibc testsuite for x86_64 and x86. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ST_INO_64_BIT): Remove macro definition. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_ST_INO_64_BIT): Do not undefine and define. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_ST_INO_64_BIT): Likewise. * sysdeps/unix/sysv/linux/fxstat64.c: Do not include <kernel-features.h>.

Remove the error handling wrapper from pow
Introduce new pow symbol version that doesn't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The wrapper is disabled for sysdeps/ieee754/dbl-64 by using empty w_pow.c and enabled for targets with their own pow implementation or ifunc dispatch on __ieee754_pow by including math/w_pow.c. The compatibility symbol version still uses the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously powl was an alias of pow, now it points to the compatibility symbol with the wrapper, because it still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g. arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The __pow_finite symbol is now an alias of pow. Both __pow_finite and pow set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header.

Remove the error handling wrapper from exp and exp2
Introduce new exp and exp2 symbol version that don't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The double precision wrappers are disabled for sysdeps/ieee754/dbl-64 by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and math/w_exp2.c files use the wrapper template and can be included by targets that have their own exp and exp2 implementations or use ifunc on the glibc internal __ieee754_exp symbol. The compatibility symbol versions still use the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously expl and exp2l were aliases of exp and exp2, now they point to the compatibility symbols with the wrapper, because they still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The _finite symbols are now aliases of the standard symbols (they have no performance advantage anymore). Both the standard symbols and _finite symbols set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header (the new macro name is __exp instead of __ieee754_exp which breaks some math.h macros).

Use common bits/shm.h for more architectures.
sysdeps/unix/sysv/linux/bits/shm.h has padding after time fields in struct shmid_ds unconditionally, and thus is only suitable for 32-bit architectures (no 64-bit configurations use this file); sysdeps/unix/sysv/linux/generic/bits/shm.h is substantively the same, except that the padding is conditioned on __WORDSIZE == 32, and so it can be used for 64-bit architectures as well. This patch adds the conditionals to sysdeps/unix/sysv/linux/bits/shm.h. The linux/generic/ version is then no longer needed and so is removed, as are the alpha and s390 versions which are also no longer needed. The other architecture-specific versions have different padding, layout, types or SHMLBA definitions and so are still needed after this change. This is essentially the same change for bits/shm.h as the bits/msq.h patch and the bits/sem.h patch. However, the details of the padding variations for the architectures that aren't changed are not all the same between msqid_ds, shmid_ds and semid_ds.

Complete sys/procfs.h unification.
This patch completes the process of unifying sys/procfs.h headers for architectures using the Linux kernel by making alpha use the generic version. That was previously deferred because alpha has different definitions of prgregset_t and prfpregset_t from other architectures, so changing to the common definitions would change C++ name mangling. To avoid such a change, a header bits/procfs-prregset.h is added, and alpha gets its own version of that header.

Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu.

Add renameat2 function [BZ #17662]
The implementation falls back to renameat if renameat2 is not available in the kernel (or in the kernel headers) and the flags argument is zero. Without kernel support, a non-zero argument returns EINVAL, not ENOSYS. This mirrors what the kernel does for invalid renameat2 flags. |

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.

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. * math/Makefile (libm-narrow-fns): Add mul.

Ignore absolute symbols in ABI tests.
A recent binutils patch <https://sourceware.org/ml/binutils/2018-04/msg00336.html> stops the MIPS linker including the _gp_disp absolute symbol in dynamic symbol tables. With older binutils, it is included for MIPS o32 (despite the use of symbol versioning), and this means that all the ABI test baselines for MIPS o32 include "_gp_disp _gp_disp A". This symbol is not meaningfully part of the ABI for shared libraries, since it always has to be resolved at static link time to the local definition for the linked object. All the other absolute symbols in ABI test baselines are the names of symbol versions. I don't think the mere existence of a symbol version with a given name - as opposed to the contents of that version if nonempty - is part of the ABI either. Thus, this patch allows the ABI tests to pass both before and after the binutils change by changing abilist.awk not to include absolute symbols in its output, and changing the baselines accordingly. Tested for x86_64, and with build-many-glibcs.py. * scripts/abilist.awk: Ignore absolute symbols. * sysdeps/mach/hurd/i386/ld.abilist: Remove absolute symbols. *

Consolidate Linux getdents{64} implementation
This patch consolidates Linux getdents{64} implementation on just the default sysdeps/unix/sysv/linux/getdents{64}{_r}.c ones. Although this symbol is used only internally, the non-LFS version still need to be build due the non-LFS getdirentries which requires its semantic. The non-LFS default implementation now uses the wordsize-32 as base which uses getdents64 syscall plus adjustment for overflow (it allows to use the same code for architectures that does not support non-LFS getdents syscall). It has two main differences to wordsize-32 one: - DIRENT_SET_DP_INO is added to handle alpha requirement to zero the padding. - alloca is removed by allocating a bounded temporary buffer (it increases stack usage by roughly 276 bytes). The default implementation handle the Linux requirements: * getdents is only built for _DIRENT_MATCHES_DIRENT64 being 0. * getdents64 is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. * A compat symbol is added for getdents64 for ABI that used to export the old non-LFS version. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/alpha/getdents.c: Add comments with alpha requirements.

linux: Consolidate sigaction implementation
This patch consolidates all Linux sigaction implementations on the default sysdeps/unix/sysv/linux/sigaction.c. The idea is remove redundant code and simplify new ports addition by following the current generic Linux User API (UAPI). The UAPI for new ports defines a generic extensible sigaction struct as: struct sigaction { __sighandler_t sa_handler; unsigned long sa_flags; #ifdef SA_RESTORER void (*sa_restorer) (void); #endif sigset_t sa_mask; }; Where SA_RESTORER is just placed for compatibility reasons (news ports should not add it). A similar definition is used on generic kernel_sigaction.h. The user exported sigaction definition is not changed, so for most architectures it requires an adjustment to kernel expected one for the syscall. The main changes are: - All architectures now define and use a kernel_sigaction struct meant for the syscall, even for the architectures where the user sigaction has the same layout of the kernel expected one (s390-64 and ia64). Although it requires more work for these architectures, it simplifies the generic implementation. Also, sigaction is hardly a hotspot where micro optimization would play an important role. - The generic kernel_sigaction definition is now aligned with expected UAPI one for newer ports, where SA_RESTORER and sa_restorer are not expected to be defined. This means adding kernel_sigaction for current architectures that does define it (m68k, nios2, powerpc, s390, sh, sparc, and tile) and which rely on previous generic definition. - Remove old MIPS usage of sa_restorer. This was removed since 2.6.27 (2957c9e61ee9c - "[MIPS] IRIX: Goodbye and thanks for all the fish"). - The remaining arch-specific sigaction.c are to handle ABI idiosyncrasies (like SPARC kernel ABI for rt_sigaction that requires an additional stub argument). So for new ports the generic implementation should work if its uses Linux UAPI. If SA_RESTORER is still required (due some architecture limitation), it should define its own kernel_sigaction.h, define it and include generic header (assuming it still uses the default generic kernel layout). Checked on x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabihf, aarch64-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, powerpc-linux-gnu, powerpc64-linux-gnu, ia64-linux-gnu and alpha-linux-gnu.

Remove unused frame.h header, sigcontextinfo.h macros.
The glibc-internal header frame.h was used in the old debug/backtrace.c but is now unused. Similarly, there are some sigcontextinfo.h macros that are used nowhere in glibc - ADVANCE_STACK_FRAME and FIRST_FRAME_POINTER were used in the old debug/backtrace.c, while SIGCONTEXT_EXTRA_ARGS, GET_FRAME, GET_STACK and CALL_SIGHANDLER were unused even before the removal of that old implementation (beyond uses of SIGCONTEXT_EXTRA_ARGS in definitions of CALL_SIGHANDLER).

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 for all configurations; f32subf64x, f32subf128, f64subf64x, 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.

Refactor Linux ARCH_FORK implementation
This patch refactors the ARCH_FORK macro and the required architecture specific header to simplify the required architecture definitions to provide the fork syscall semantic and proper document current Linux clone ABI variant. Instead of require the reimplementation of arch-fork.h header, this patch changes the ARCH_FORK to an inline function with clone ABI defined by kernel-features.h define. The generic kernel ABI meant for newer ports is used as default and redefine if the architecture requires. Checked on x86_64-linux-gnu and i686-linux-gnu.

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. * math/Makefile (libm-narrow-fns): Add add.

Alpha: Add wrappers to get/setrlimit64 to fix RLIM64_INFINITY constant [BZ #22648]
RLIM64_INFINITY was supposed to be a glibc convention rather than
anything seen by the kernel, but it ended being passed to the kernel
through the prlimit64 syscall.
* On the kernel side, the value is defined for the prlimit64 syscall for
all architectures in include/uapi/linux/resource.h:
#define RLIM64_INFINITY (~0ULL)
* On the kernel side, the value is defined for getrlimit and setrlimit
in arch/alpha/include/uapi/asm/resource.h
#define RLIM_INFINITY 0x7ffffffffffffffful
* On the GNU libc side, the value is defined in
sysdeps/unix/sysv/linux/alpha/bits/resource.h:
# define RLIM64_INFINITY 0x7fffffffffffffffLL
This was not an issue until the getrlimit and setrlimit glibc functions
have been changed in commit

Add _Float32 function aliases.
This patch concludes filling out TS 18661-3 support for different types by adding *f32 function aliases of float functions to support _Float32. As with _Float64 and _Float32x, this is supported for all glibc configurations. As with the previous such patches there are some x86 ulps updates because of inline functions present for float but not for _Float32. The patch also has the usual bits/floatn-common.h update, symbol versions, ABI baselines updates, test enablement and documentation. Tested for x86_64 and x86, and with build-many-glibcs.py, with both GCC 6 and GCC 7. * bits/floatn-common.h (__HAVE_FLOAT32): Define to 1. * manual/math.texi (Mathematics): Document support for _Float32. * math/Makefile (test-types): Add float32. * math/Versions (GLIBC_2.27): Add _Float32 functions. * stdlib/Versions (GLIBC_2.27): Likewise. * wcsmbs/Versions (GLIBC_2.27): Likewise. * sysdeps/unix/sysv/linux/aarch64/libc.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Likewise. * sysdeps/i386/fpu/libm-test-ulps: Likewise. * sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise. |

Add _Float64, _Float32x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64 and *f32x function aliases, supporting _Float64 and _Float32x, as aliases for double functions. These types are supported for all glibc configurations. The API corresponds exactly to that for _Float128 and _Float64x. _Float32 aliases to float functions remain to be added in subsequent patches to complete this process (then there are a few miscellaneous functions in TS 18661-3 to implement that aren't simply versions of existing functions for new types). The patch enables the feature in bits/floatn-common.h, adds symbol versions and documentation with updates to ABI baselines, and arranges for the libm functions for the new types to be tested. As with the _Float64x changes there are some x86 ulps updates because of header inlines not used for the new types (and one other change to the non-multiarch libm-test-ulps, which I suppose comes from using a different compiler version / configuration from when it was last regenerated). Tested for x86_64 and x86, and with build-many-glibcs.py, with both GCC 6 and GCC 7. * bits/floatn-common.h (__HAVE_FLOAT64): Define to 1.

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

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. * sysdeps/ia64/Makeconfig (float64x-alias-fcts): New variable. * sysdeps/ieee754/float128/Makeconfig (float64x-alias-fcts): Likewise. * sysdeps/ieee754/ldbl-128/Makeconfig (float64x-alias-fcts): Likewise. * sysdeps/x86/Makeconfig: New file. * bits/floatn-common.h (__HAVE_FLOAT64X): Remove macro.

Linux: Add memfd_create system call wrapper
The system call is somewhat obscure because it is closely related to file descriptor sealing. However, it is also the recommended way to create alias mappings, which is why it has more general use. No emulation is provided. Except for the name of the /proc/self/fd links, it would be possible to implement an approximation using O_TMPFILE and tmpfs, but this does not appear to be worth the added complexity.

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 with both GCC 6 and GCC 7. * sysdeps/ieee754/ldbl-128/Makeconfig: New file. * sysdeps/ieee754/ldbl-128/bits/floatn.h: Likewise. * sysdeps/ieee754/ldbl-128/float128-abi.h: Likewise. * sysdeps/generic/libm-alias-ldouble.h: Include <bits/floatn.h>.

Linux: Consolidate {RTLD_}SINGLE_THREAD_P definition
Current GLIBC has two ways to implement the single thread optimization on syscalls to avoid calling the cancellation path: either by using global variables (__{libc,pthread}_multiple_thread) or by accessing the TCB field (defined by TLS_MULTIPLE_THREADS_IN_TCB). Both the variables and the macros to acces its value are defined in the architecture sysdep-cancel.h header. This patch consolidates its definition on only one header, sysdeps/unix/sysv/linux/sysdep-cancel.h, and adds a new define (SINGLE_THREAD_BY_GLOBAL) which the architecture defines if it prefer to use the global variables instead of the TCB field. This is an optimization, so if the architecture does not define it, the TCB method will be used as default.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version b5ec983 (glob: simplify symlink detection). The only difference to gnulib code is * DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there were not already defined. Gnulib code which uses HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead the patch check for each definition instead. Also, the patch requires additional globfree and globfree64 files for compatibility version on some architectures.

Remove NO_CANCELLATION macro
The NO_CANCELLATION macro is used currently on generic headers to define non cancellable syscalls and on Linux fcntl to implement the non cancellable variation. Former should be single-handled by not-cancel.h header and former could be simplified build both cancellable and non cancellable for default objects and alias the non-cancellable to default one for rtld ones (since Linux already support cancellation as default). This patch thus removes the NO_CANCELLATION macro and its usage. The generic non cancellable fcntl is route to internal fcntl. Checked on x86_64-linux-gnu and i686-linux-gnu.

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

Remove cancellation support for syscall generation
This patch removes the cancellation mark from the auto-generation syscall script. Now all the cancellable syscalls are done throught C code using the SYSCALL_CANCEL macro. It simplifies the assembly required to each architecture port, since the SYSCALL_CANCEL uses the already defined INLINE_SYSCALL macros, and allows a more straigh fix on cancellation machanism (since no more specific assembly fixes will be required). Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.A Also with build-many-glibc.py with remaning touched architectures. * sysdeps/unix/make-syscalls.sh: Remove cancellable tagging for syscall definitions. * sysdeps/unix/syscall-template.S (SYSCALL_CANCELLABLE): Remove definition. * sysdeps/unix/sysv/linux/aarch64/sysdep-cancel.h (PSEUDO): Remove definition.

Fix uc_* namespace (bug 21457).
The standard members of ucontext_t, in all standard versions with that type, are uc_link, uc_sigmask, uc_stack and uc_mcontext. The uc_* namespace is mostly reserved for additions to the structure. However, in XPG4.2, it's only reserved when <ucontext.h> is included, not when <signal.h> is included, while <signal.h> is required to define ucontext_t (but not allowed to make visible other symbols from <ucontext.h>). Thus, nonstandard members should avoid uc_* names. Some already do use __uc_*, but others don't; most architectures (all except ia64, I think) have a member uc_flags and some have additional members beyond that. This patch makes nonstandard members have an __ prefix unless __USE_MISC is defined. Members whose names indicate they are solely padding / reserved for future use are renamed unconditionally to use the __glibc_reserved1 naming convention. This is part of the preparation for a revised version of the mcontext_t / sigcontext patch to be able to eliminate all 13 of the miscellaneous XFAILs in conform/Makefile, rather than only 11 of them as at present (at least one further fix on top of this one will be needed for that as well). Tested for x86_64, and with build-many-glibcs.py. [BZ #21457] * sysdeps/arm/sys/ucontext.h (__ctx): Move undefine further down. (ucontext_t): Use __ctx with uc_flags.

Do not use __ptr_t.
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

Fix XPG4.2 bits/sigaction.h namespace (bug 21899).
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and SA_NODEFER should be defined in signal.h, but they are only defined for other standards at present. This patch fixes the various bits/sigaction.h headers accordingly. All the fixes are essentially the same, except those for SPARC and Tile. For SPARC, the header (a) spuriously defined various nonstandard macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some standard macros as aliases of nonstandard ones instead of the other way round. This patch fixes the SPARC header to handle these macros the same way and with the same conditions as those for other architectures, so the standard macros are the primary ones and the other ones are defined only for __USE_MISC and are aliases of the standard ones where applicable. For Tile, the header spuriously defined the nonstandard macro SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved to __USE_MISC. (Those nonstandard macros are in a reserved namespace, but it seems desirable to be consistent between architectures as far as possible, and so not define them in standard modes anywhere.)

Rename struct ucontext tag (bug 21457).
The ucontext_t type has a tag struct ucontext. As with previous such issues for siginfo_t and stack_t, this tag is not permitted by POSIX (is not in a reserved namespace), and so namespace conformance means breaking C++ name mangling for this type. In this case, the type does need to have some tag rather than just a typedef name, because it includes a pointer to itself. This patch uses struct ucontext_t as the new tag, so the type is mangled as ucontext_t (the POSIX *_t reservation applies in all namespaces, not just the namespace of ordinary identifiers). Another reserved name such as struct __ucontext could of course be used. Because of other namespace issues, this patch does not by itself fix bug 21457 or allow any XFAILs to be removed.

Call exit directly in clone (BZ #21512)
On aarch64, alpha, arm, hppa, mips, nios2, powerpc, sh, sparc, tile, and x86_64 the clone syscall jumps to _exit after the child execution and the function ends the process execution by calling exit_group. This behavior have a small issue where threads created with CLONE_THREAD using clone syscall directly will eventually exit the whole group altogether instead of just the thread created. Also, s390, microblaze, ia64, i386, and m68k differs by calling exit syscall directly. This patch changes all architectures to call the exit syscall directly, as for s390, microblaze, ia64, i386, and m68k. This do not have change glibc internal behavior in any sort, since the only usage of clone implementation in posix_spawn calls _exit directly in the created child (fork uses a direct call to clone). Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, powerpc-linux-gnu, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu.

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.

Define struct rusage in sys/wait.h when required (bug 21575).
Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require sys/wait.h to include the definition of struct rusage. This is missing in glibc. This patch adds the required definition. struct rusage is moved to a new header bits/types/struct_rusage.h to avoid bringing in the whole of sys/resource.h (although the standards in question do allow the whole of sys/resource.h to be brought in). In the five bits/resource.h headers, the only variation between the definitions of struct rusage is that the sysdeps/unix/sysv/linux version is prepared for x32 (by having anonymous unions with __syscall_slong_t fields) and the others are not. Thus, this version is suitable for use generically (everything other than x32 simply has __syscall_slong_t the same as long int, so there are no API or ABI changes involved, and anonymous unions are already a required language feature for glibc headers elsewhere), and this patch uses it as a base for the single implementation of bits/types/struct_rusage.h. Tested for x86_64, and with build-many-glibcs.py. [BZ #21575] * resource/bits/types/struct_rusage.h: New file. * include/bits/types/struct_rusage.h: Likewise. * bits/resource.h (struct rusage): Include <bits/types/struct_rusage.h> instead of defining here. * sysdeps/unix/sysv/linux/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/alpha/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/mips/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/resource.h (struct rusage): Likewise. * resource/Makefile (headers): Add bits/types/struct_rusage.h. * posix/sys/wait.h [__USE_XOPEN_EXTENDED && !__USE_XOPEN2K8]: Include <bits/types/struct_rusage.h> |

Remove __need macros from errno.h (__need_Emath, __need_error_t).
This is fairly complicated, not because the users of __need_Emath and __need_error_t have complicated requirements, but because the core changes had a lot of fallout. __need_error_t exists for gnulib compatibility in argz.h and argp.h. error_t itself is a Hurdism, an enum containing all the E-constants, so you can do 'p (error_t) errno' in gdb and get a symbolic value. argz.h and argp.h use it for function return values, and they want to fall back to 'int' when that's not available. There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic. Reorganize file. Declare errno here. When __ASSEMBLER__ is defined, don't declare anything other than the E-constants. * include/errno.h: Change conditional for exposing internal declarations to (not _ISOMAC and not __ASSEMBLER__). * bits/errno.h: Remove logic for __need_Emath.

Define SIG_HOLD for XPG4 (bug 21538).
Various bits/signum.h headers define SIG_HOLD if __USE_UNIX98. That should be __USE_XOPEN, as this macro is in XPG4. This patch fixes the conditionals accordingly. Because of other header bugs, this does not allow any XFAILs to be removed (however, the XPG4/signal.h/conform XFAIL only depends on a few such straightforward header bugs, not on the more complicated to fix ucontext_t issues, as ucontext_t isn't included in signal.h in XPG4).

Fix struct sigaltstack namespace (bug 21517).
glibc defines the stack_t type with the tag struct sigaltstack. This is not permitted by POSIX; sigaltstack is only reserved with file scope in the namespace of ordinary identifiers, not the tag namespace, and in the case where stack_t is obtained from ucontext.h rather than signal.h, it's not reserved with file scope at all. This patch removes the tag accordingly and updates uses in glibc of struct sigaltstack. This is similar to the removal of the "struct siginfo" tag a few years ago: C++ name mangling changes are an unavoidable consequence. A NEWS item is added to note the changed mangling. There is inevitably some risk of breaking builds of anything that relies on the struct sigaltstack name (though the first few hits I looked at from codesearch.debian.net generally seemed to involve code that could use the stack_t name conditionally, so depending on how they determine the conditionals they may work with glibc not defining the struct tag anyway). Tested for x86_64 and x86, and with build-many-glibcs.py.

Fix more namespace issues in sys/ucontext.h (bug 21457).
Continuing the fixes for namespace issues in sys/ucontext.h, this patch moves various symbols into the implementation namespace in the absence of __USE_MISC. As with previous changes, it is nonexhaustive, just covering more straightforward cases. Structure fields are generally changed to have a prefix __ in the absence of __USE_MISC, via a macro __ctx (used without a space before the open parenthesis, since the result is a single identifier). Various macros such as NGREG also have leading __ added. No changes are made to structure tags (and thus to C++ name mangling), except that in the (unused) file sysdeps/i386/sys/ucontext.h, structures defined inside other structures as the type for a field have their tags removed in the non-__USE_MISC case (those structure tags would not in any case have been visible in C++, because in C++ the scope of such a tag is limited to the containing structure). No changes are made to the contents of bits/sigcontext.h, or to whether it is included. Because of remaining namespace issues, this patch does not yet fix the bug or allow any XFAILs to be removed.

posix: Implement preadv2 and pwritev2
This patch adds support of preadv2 and pwritev2 which are similar to preadv/pwritev but with an extra flag argument. As for preadv/pwritev both interfaces are added a non-standard GNU API. For default 'posix' implementation trying to emulate the Linux supported flags is troublesome: * We can not temporary change the file state of the O_DSYNC and O_SYNC flags to emulate RWF_{D}SYNC (attempts to change the state of using fcntl are silently ignored). * IOCB_HIPRI requires the file opened in O_DIRECT and uses an internal semantic not provided by any other flag (O_NONBLOCK for instance). So default sysdeps/posix implementations fails with EOPNOTSUPP for any non supported flag (which are none currently) calls generic preadv/pwritev. Basically this implementation supports only preadv2 called as preadv (with flags sets to 0). The Linux one uses the preadv2/pwritev2 syscall if defined, otherwise it call preadv/writev. Instead of using the previous __ASSUME_* to unconditionally issue the syscall (and avoid building the fallback routine), it call pread/write if the preadv2/pwritev2 syscalls fails. The idea is just avoid adding another __ASSUME_* and checking each architecture on every kernel bump and simplify code conditionals.

Add reallocarray function
The reallocarray function is an extension from OpenBSD. It is an integer-overflow-safe replacement for realloc(p, X*Y) and malloc(X*Y) (realloc(NULL, X*Y)). It can therefore help in preventing certain security issues in code. This is an updated version of a patch originally submitted by Rüdiger Sonderfeld in May 2014 [1]. Checked on i686-linux-gnu and x86_64-linux-gnu.

Fix sys/ucontext.h namespace from signal.h etc. inclusion (bug 21457).
The various sys/ucontext.h headers include <signal.h> and all the headers split out of <bits/sigstack.h>. (Except that the powerpc version does not include <signal.h>.) None of the standard versions defining ucontext.h require or permit such inclusions; rather, they all say that the stack_t and sigset_t types from signal.h are defined. This patch fixes the headers to include just the bits/ headers for those types (and the existing includes of bits/sigcontext.h). Since bits/types/sigset_t.h is now being included instead of bits/types/__sigset_t.h, __sigset_t uses in the headers are replaced by direct use of the public sigset_t type. sysdeps/unix/sysv/linux/x86/bits/sigcontext.h was relying on the prior inclusion of <signal.h> to define types such as __uint32_t, so gets a bits/types.h include added to provide those types. Although one could keep some or all of the includes under a __USE_MISC conditional, that seems unnecessary to me, especially given the lack of a <signal.h> include in the powerpc version meaning that portable programs already cannot rely on such an include. Tested for x86_64 and x86, and with build-many-glibcs.py. As with other such fixes, more namespace issues remain so this does not permit any XFAILs to be removed or bugs to be closed.

Remove __need macros from signal.h.
The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t, sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a scalar, so it's now directly available from bits/types.h. The others get bits/types/ headers. Side effects include: There have been small changes to which non-signal headers expose which subset of the signal-related types. A couple of architectures' nested siginfo_t fields had to be renamed to prevent undesired macro expansion. Internal code that wants to manipulate signal masks must now include <sigsetops.h> (which is not installed) and should be aware that __sigaddset, __sigandset, __sigdelset, __sigemptyset, and __sigorset no longer return a value (unlike the public API). Relatedly, the public signal.h no longer declares any of those functions. The obsolete sigmask() macro no longer has a system-specific definition -- in the cases where it matters, it didn't work anyway.

Split up bits/sigstack.h.
bits/sigstack.h contains four things: the legacy struct sigstack type, the preferred stack_t type, the SS_* enum values and macros for signal stack sizes. These vary in different ways between glibc configurations; in particular, the stack sizes vary much more than any of the other pieces. Furthermore, these pieces have different standard namespace rules for when they should be visible (not currently visible in conform/ results both because the relevant tests are XFAILed for sys/ucontext.h namespace issues, and because some of the expectations are incorrect in the same way as the headers, e.g. neither expectations nor headers reflect that current POSIX no longer has either the sigstack function or the sigstack structure). To reduce duplication of identical definitions, and facilitate namespace fixes without requiring the same feature test macro conditions to be repeated in many versions of the same header, this patch splits bits/sigstack.h up into four headers. It keeps the stack size macros, while new bits/types/struct_sigstack.h, bits/types/stack_t.h and bits/ss_flags.h are added for the other pieces. bits/types/struct_sigstack.h is the same everywhere, bits/types/stack_t.h has three variants different in the order of the structure elements (generic = MIPS Linux, and other Linux), and bits/ss_flags.h has generic and Linux variants. This patch includes the new headers everywhere that included <bits/sigstack.h>, so should cause no difference to what any public header defines. Subsequent namespace fixes would then remove or condition some of those includes. There should be no conflicts with Zack's changes to signal.h types, beyond the trivial conflict of both making additions to signal/Makefile's headers list; the two patches affect disjoint sets of types and other definitions.

posix: Consolidate Linux sigsuspend implementation
This patch consolidates the sigsuspend Linux syscall generation on sysdeps/unix/sysv/linux/sigsuspend.c. It basically removes the alpha assembly version which call the old sigsusped interface using only the first doubleword from sigset. Current minimum supported kernel on alpha (3.2) enforces rt_sigsuspend on the architecture (__ARCH_WANT_SYS_RT_SIGSUSPEND option on kernel), so it is possible to use the default implementation. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu. * sysdeps/unix/sysv/linux/alpha/sigsuspend.S: Remove file. * sysdeps/unix/sysv/linux/sigsuspend.c: Simplify include list. * nptl/Makefile (CFLAGS-sigsuspend.c): New rule. * sysdeps/unix/sysv/linux/sparc/sparc64/Makefile (CFLAGS-sigsuspend.c): Remove rule. |

Define more termios.h macros unconditionally for alpha (bug 21277).
termios.h should define IUCLC for UNIX98 and older XSI standards. The sysdeps/unix/sysv/linux/alpha version defines it only if __USE_MISC, so causing some conform/ tests to fail. Other versions define it unconditionally (I* being a reserved namespace for this header); the API should be consistent between architectures in the absence of a clear reason for it to differ (and given that a symbol is part of the API on two architectures, I don't see any reason for the feature test macros required ever to differ between those architectures), so this patch makes the alpha version define it unconditionally as well. Two non-POSIX macros alongside it, IMAXBEL and IUTF8, are also defined unconditionally on other architectures, so this patch makes them consistent by defining them unconditionally on alpha as well. Tested (compilation only) with build-many-glibcs.py. [BZ #21277] * sysdeps/unix/sysv/linux/alpha/bits/termios.h (IUCLC): Define unconditionally. (IMAXBEL): Likewise. (IUTF8): Likewise. |

Make alpha termios.h define IXANY unconditionally (bug 21259).
sysdeps/unix/sysv/linux/alpha/bits/termios.h defines IXANY only if __USE_MISC. But it's in the base standard for POSIX.1:2008, and XSI-shaded in previous standards. This patch makes the header define it unconditionally, like other versions of this header do (it's always reserved by standards that don't require it, so defining unconditionally is OK by the standards). Tested (compilation only) for alpha with build-many-glibcs.py. Note that there are still termios.h conformtest failures after this patch because of other issues with the alpha version of this header. [BZ #21259] * sysdeps/unix/sysv/linux/alpha/bits/termios.h (IXANY): Define unconditionally, not just for [__USE_MISC]. |

New condvar implementation that provides stronger ordering guarantees.
This is a new implementation for condition variables, required after http://austingroupbugs.net/view.php?id=609 to fix bug 13165. In essence, we need to be stricter in which waiters a signal or broadcast is required to wake up; this couldn't be solved using the old algorithm. ISO C++ made a similar clarification, so this also fixes a bug in current libstdc++, for example. We can't use the old algorithm anymore because futexes do not guarantee to wake in FIFO order. Thus, when we wake, we can't simply let any waiter grab a signal, but we need to ensure that one of the waiters happening before the signal is woken up. This is something the previous algorithm violated (see bug 13165). There's another issue specific to condvars: ABA issues on the underlying futexes. Unlike mutexes that have just three states, or semaphores that have no tokens or a limited number of them, the state of a condvar is the *order* of the waiters. A waiter on a semaphore can grab a token whenever one is available; a condvar waiter must only consume a signal if it is eligible to do so as determined by the relative order of the waiter and the signal. Therefore, this new algorithm maintains two groups of waiters: Those eligible to consume signals (G1), and those that have to wait until previous waiters have consumed signals (G2). Once G1 is empty, G2 becomes the new G1. 64b counters are used to avoid ABA issues. This condvar doesn't yet use a requeue optimization (ie, on a broadcast, waking just one thread and requeueing all others on the futex of the mutex supplied by the program). I don't think doing the requeue is necessarily the right approach (but I haven't done real measurements yet): * If a program expects to wake many threads at the same time and make that scalable, a condvar isn't great anyway because of how it requires waiters to operate mutually exclusive (due to the mutex usage). Thus, a thundering herd problem is a scalability problem with or without the optimization. Using something like a semaphore might be more appropriate in such a case. * The scalability problem is actually at the mutex side; the condvar could help (and it tries to with the requeue optimization), but it should be the mutex who decides how that is done, and whether it is done at all. * Forcing all but one waiter into the kernel-side wait queue of the mutex prevents/avoids the use of lock elision on the mutex. Thus, it prevents the only cure against the underlying scalability problem inherent to condvars. * If condvars use short critical sections (ie, hold the mutex just to check a binary flag or such), which they should do ideally, then forcing all those waiter to proceed serially with kernel-based hand-off (ie, futex ops in the mutex' contended state, via the futex wait queues) will be less efficient than just letting a scalable mutex implementation take care of it. Our current mutex impl doesn't employ spinning at all, but if critical sections are short, spinning can be much better. * Doing the requeue stuff requires all waiters to always drive the mutex into the contended state. This leads to each waiter having to call futex_wake after lock release, even if this wouldn't be necessary.

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).

Refactor Linux ipc_priv header
Some architectures support the old-style IPC and require IPC_64 equal to 0x100 to be passed along SysV IPC syscalls, while new architectures should default to new IPC version (without the flags being set). This patch refactor current ipc_priv.h Linux headers in two directions: - Remove cross platform references (for instance alpha including powerpc definition) and add required definition for each required port. The idea is to avoid tie one architecture definition with another and make platform change independent. - Move all common definitions (the ipc syscall commands) on a common header, ipc_ops.h. * sysdeps/unix/sysv/linux/aarch64/ipc_priv.h: New file. * sysdeps/unix/sysv/linux/alpha/ipc_priv.h: Avoid included other arch definition and define its own. * sysdeps/unix/sysv/linux/ipc_ops.h: New file. * sysdeps/unix/sysv/linux/x86_64/ipc_priv.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/ipc_priv.h: Likewise. * sysdeps/unix/sysv/linux/mips/ipc_priv.h: Remove file. * sysdeps/unix/sysv/linux/mips/mips64/ipc_priv.h: New file. * sysdeps/unix/sysv/linux/ipc_priv.h: Move ipc syscall operation definitions to common header. * sysdeps/unix/sysv/linux/powerpc/ipc_priv.h: Use common syscall operation from ipc_ops.h. |

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

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

Refactor long double information into bits/long-double.h.
Information about whether the ABI of long double is the same as that of double is split between bits/mathdef.h and bits/wordsize.h. When the ABIs are the same, bits/mathdef.h defines __NO_LONG_DOUBLE_MATH. In addition, in the case where the same glibc binary supports both -mlong-double-64 and -mlong-double-128, bits/wordsize.h defines __LONG_DOUBLE_MATH_OPTIONAL, along with __NO_LONG_DOUBLE_MATH if this particular compilation is with -mlong-double-64. As part of the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, this patch puts all that information in a single header, bits/long-double.h. It is included from sys/cdefs.h alongside the include of bits/wordsize.h, so other headers generally do not need to include bits/long-double.h directly. Previously, various bits/mathdef.h headers and bits/wordsize.h headers had this long double information (including implicitly in some bits/mathdef.h headers through not having the defines present in the default version). After the patch, it's all in six bits/long-double.h headers. Furthermore, most of those new headers are not architecture-specific. Architectures with optional long double all use the ldbl-opt sysdeps directory, either in the order (ldbl-64-128, ldbl-opt, ldbl-128) or (ldbl-128ibm, ldbl-opt). Thus a generic header for the case where long double = double, and headers in ldbl-128, ldbl-96 and ldbl-opt, suffices to cover every architecture except for cases where long double properties vary between different ABIs sharing a set of installed headers; fortunately all the ldbl-opt cases share a single compiler-predefined macro __LONG_DOUBLE_128__ that can be used to tell whether this compilation is -mlong-double-64 or -mlong-double-128. The two cases where a set of headers is shared between ABIs with different long double properties, MIPS (o32 has long double = double, other ABIs use ldbl-128) and SPARC (32-bit has optional long double, 64-bit has required long double), need their own bits/long-double.h headers. As with bits/wordsize.h, multiple-include protection for this header is generally implicit through the include guards on sys/cdefs.h, and multiple inclusion is harmless in any case. There is one subtlety: the header must not define __LONG_DOUBLE_MATH_OPTIONAL if __NO_LONG_DOUBLE_MATH was defined before its inclusion, because doing so breaks how sysdeps/ieee754/ldbl-opt/nldbl-compat.h defines __NO_LONG_DOUBLE_MATH itself before including system headers. Subject to keeping that working, it would be reasonable to move these macros from defined/undefined #ifdef to always-defined 1/0 #if semantics, but this patch does not attempt to do so, just rearranges where the macros are defined. After this patch, the only use of bits/mathdef.h is the alpha one for modifying complex function ABIs for old GCC. Thus, all versions of the header other than the default and alpha versions are removed, as is the include from math.h. Tested for x86_64 and x86. Also did compilation-only testing with build-many-glibcs.py. * bits/long-double.h: New file. * sysdeps/ieee754/ldbl-128/bits/long-double.h: Likewise. * sysdeps/ieee754/ldbl-96/bits/long-double.h: Likewise. * sysdeps/ieee754/ldbl-opt/bits/long-double.h: Likewise. * sysdeps/mips/bits/long-double.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/long-double.h: Likewise. * math/Makefile (headers): Add bits/long-double.h. * misc/sys/cdefs.h: Include <bits/long-double.h>. * stdlib/strtold.c: Include <bits/long-double.h> instead of <bits/wordsize.h>. * bits/mathdef.h [!_COMPLEX_H]: Do not allow inclusion.

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. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (llogb): New declaration. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (llogb): New macro. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (__FP_LONG_MAX): New macro.

Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]
This change moves the main implementation of _dl_catch_error, _dl_signal_error to libc.so, where TLS variables can be used directly. This removes a writable function pointer from the rtld_global variable. For use during initial relocation, minimal implementations of these functions are provided in ld.so. These are eventually interposed by the libc.so implementations. This is implemented by compiling elf/dl-error-skeleton.c twice, via elf/dl-error.c and elf/dl-error-minimal.c. As a side effect of this change, the static version of dl-error.c no longer includes support for the _dl_signal_cerror/_dl_receive_error mechanism because it is only used in ld.so. |

Add setpayloadsig, setpayloadsigf, setpayloadsigl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayloadsig functions for glibc; these are like the setpayload functions, but produce a signaling NaN instead of a quiet NaN. The substance of the implementation was included with the setpayload implementation, so the new files here just need to wrap the main files with different defines to build the new functions. Because the functions store a signaling NaN via a pointer and the libm-test macros choose a suitable initial value for the variable in such a case by comparing with the expected value, the relevant macro needs to clear exceptions after FE_INVALID may have been raised by that comparison. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (setpayloadsig): New declaration. * math/Versions (setpayloadsig): New libm symbol at version GLIBC_2.25.

Remove cached PID/TID in clone
This patch remove the PID cache and usage in current GLIBC code. Current usage is mainly used a performance optimization to avoid the syscall, however it adds some issues: - The exposed clone syscall will try to set pid/tid to make the new thread somewhat compatible with current GLIBC assumptions. This cause a set of issue with new workloads and usecases (such as BZ#17214 and [1]) as well for new internal usage of clone to optimize other algorithms (such as clone plus CLONE_VM for posix_spawn, BZ#19957). - The caching complexity also added some bugs in the past [2] [3] and requires more effort of each port to handle such requirements (for both clone and vfork implementation). - Caching performance gain in mainly on getpid and some specific code paths. The getpid performance leverage is questionable [4], either by the idea of getpid being a hotspot as for the getpid implementation itself (if it is indeed a justifiable hotspot a vDSO symbol could let to a much more simpler solution). Other usage is mainly for non usual code paths, such as pthread cancellation signal and handling. For thread creation (on stack allocation) the code simplification in fact adds some performance gain due the no need of transverse the stack cache and invalidate each element pid. Other thread usages will require a direct getpid syscall, such as cancellation/setxid signal, thread cancellation, thread fail path (at create_thread), and thread signal (pthread_kill and pthread_sigqueue). However these are hardly usual hotspots and I think adding a syscall is justifiable. It also simplifies both the clone and vfork arch-specific implementation. And by review each fork implementation there are some discrepancies that this patch also solves: - microblaze clone/vfork does not set/reset the pid/tid field - hppa uses the default vfork implementation that fallback to fork. Since vfork is deprecated I do not think we should bother with it. The patch also removes the TID caching in clone. My understanding for such semantic is try provide some pthread usage after a user program issue clone directly (as done by thread creation with CLONE_PARENT_SETTID and pthread tid member). However, as stated before in multiple discussions threads, GLIBC provides clone syscalls without further supporting all this semantics. I ran a full make check on x86_64, x32, i686, armhf, aarch64, and powerpc64le. For sparc32, sparc64, and mips I ran the basic fork and vfork tests from posix/ folder (on a qemu system). So it would require further testing on alpha, hppa, ia64, m68k, nios2, s390, sh, and tile (I excluded microblaze because it is already implementing the patch semantic regarding clone/vfork).

Add setpayload, setpayloadf, setpayloadl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayload functions for glibc; these set a number (pointed to by a function argument) to a quiet NaN with the given payload, or to +0 if the given payload is not valid. The implementations are structured to allow the substance of the implementation to be shared with the setpayloadsig functions when those are added. The semantics in the TS are not entirely clear in the case where the payload passed to the function is zero (see discussion on the WG14 reflector last month). This patch implements what seems the most sensible interpretation, that -0 is never valid to give as the payload, but +0 is valid in the case where the kind of NaN being generated has its high mantissa bit set so payload 0 is actually possible in such a NaN. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (setpayload): New declaration. * math/Versions (setpayload): New libm symbol at version GLIBC_2.25.

Consolidate Linux setrlimit and getrlimit implementation
This patch consolidates all Linux setrlimit and getrlimit on the default
sysdeps/unix/sysv/linux/{set,get}rlimit{64}.c. It contains two exceptions:
1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19
and higher due a broken RLIM64_INFINITY constant.
2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB
limit. I am not sure if it is required, but a RLIM_INFINITY fix [1]
change its definition without adding a compat symbol. This patch does
not aim to address this possible issue, it follow current symbol
export.
The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64)
and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This
code path is only used on kernel older than 2.6.36 (basically now only x86)
and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once
x86 moves to be on par with other architectures regarding minimum kernel
supported we can get rid of using old syscalls and default path.
A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as
default for 64 bits ports. This allows the default implementation to avoid
{get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit.
Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a
sanity build plus check-abi on all other supported architectures.

Update alpha localplt.data.
This patch updates alpha localplt.data so the localplt test passes in my compile-only all-ABIs glibc testing. The failures I see without this patch are: Missing required PLT reference: ld.so: __tls_get_addr Missing required PLT reference: ld.so: free Now, __tls_get_addr can be made optional. For free, rather than making it optional as in libc.so it seems better to mark all the malloc-related symbols in both libc.so and ld.so as allowing an R_ALPHA_GLOB_DAT relocation as an alternative to using a PLT entry, so this patch does so. Tested for alpha. * sysdeps/unix/sysv/linux/alpha/localplt.data: Make __tls_get_addr optional in ld.so. Allow R_ALPHA_GLOB_DAT relocation for malloc, calloc, realloc, free, memalign and __libc_memalign rather than making them optional. |

Consolidate lseek/lseek64/llseek implementations
This patch consolidates all Linux lseek/lseek64/llseek implementation in on on sysdeps/unix/sysv/linux/lseek{64}.c. It also removes the llseek file and instead consolidate the LFS lseek implementation on lseek64.c as for other LFS symbols implementations. The general idea is: - lseek: ABIs that not define __OFF_T_MATCHES_OFF64_T will preferable use __NR__llseek if kernel supports it, otherwise they will use __NR_lseek. ABIs that defines __OFF_T_MATCHES_OFF64_T won't produce any symbol. - lseek64: ABIs with __OFF_T_MATCHES_OFF64_T will preferable use __NR_lseek (since it will use 64-bit arguments without low/high splitting) and __NR__llseek if __NR_lseek is not defined (for some ILP32 ports). - llseek: files will be removed and symbols will be aliased ot lseek64. ABI without __OFF_T_MATCHES_OFF64_T and without __NR_llseek (basically MIPS64n32 so far) are covered by building lseek with off_t as expected and lseek64 using __NR_lseek (as expected for off64_t being passed using 64-bit registers). For this consolidation I mantained the x32 assembly specific implementation because to correctly fix this it would required both the x32 fix for {INLINE,INTERNAL}_SYSCALL [1] and a wrapper to correctly subscribe it to return 64 bits instead of default 32 bits (as for times). It could a future cleanup. It is based on my previous {INTERNAL,INLINE}_SYSCALL_CALL macro [2], although it is mainly for simplification.

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.

Add getpayload, getpayloadf, getpayloadl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the getpayload functions for glibc; these extract the NaN payload (from an argument passed as a pointer, for which corresponding libm-test support is added) and return it in the same floating-point type. The return value of these functions is unspecified for non-NaN arguments; the patch does the simplest thing to implement, which is that the functions do not check whether the argument is a NaN and just treat the relevant bits of the representation as a payload regardless. A conversion from integer to floating-point is used to produce the required return value, except in the ldbl-128 case; as 128-bit integers are not supported for all configurations using ldbl-128, the code constructs the required floating-point representation of the return value directly instead.

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 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.

Installed-header hygiene (BZ#20366): stack_t.
sys/ucontext.h unconditionally uses stack_t, and it does not make sense to change that. But signal.h only declares stack_t under __USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is already in a bits header, bits/sigstack.h, but that header insists on only being included by signal.h, so we have to change that as well as all of the sys/ucontext.h variants. (Some but not all variants of bits/sigcontext.h, which sys/ucontext.h may also need, had already received this adjustment; for consistency, I made them all the same, even if that's not strictly necessary in some configurations.) bits/sigcontext.h and bits/sigstack.h also all need to receive multiple inclusion guards. * sysdeps/generic/sys/ucontext.h * sysdeps/arm/sys/ucontext.h * sysdeps/i386/sys/ucontext.h * sysdeps/m68k/sys/ucontext.h * sysdeps/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h * sysdeps/unix/sysv/linux/arm/sys/ucontext.h * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h * sysdeps/unix/sysv/linux/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h * sysdeps/unix/sysv/linux/s390/sys/ucontext.h * sysdeps/unix/sysv/linux/sh/sys/ucontext.h * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h * sysdeps/unix/sysv/linux/tile/sys/ucontext.h * sysdeps/unix/sysv/linux/x86/sys/ucontext.h: Include both bits/sigcontext.h and bits/sigstack.h.

Installed-header hygiene (BZ#20366): time.h types.
Many headers are expected to expose a subset of the type definitions in time.h. time.h has a whole bunch of messy logic for conditionally defining some its types and structs, but, as best I can tell, this has never worked 100%. In particular, __need_timespec is ineffective if _TIME_H has already been defined, which means that if you compile #include <time.h> #include <sched.h> with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get In file included from test.c:2:0: /usr/include/sched.h:74:57: warning: "struct timespec" declared inside parameter list will not be visible outside of this definition or declaration extern int sched_rr_get_interval (__pid_t __pid, struct timespec *__t) __THROW; ^~~~~~~~ And if you want to _use_ sched_rr_get_interval in a TU compiled that way, you're hosed. This patch replaces all of that with small bits/types/TYPE.h headers as introduced earlier. time.h and bits/time.h are now *much* simpler, and a lot of other headers are slightly simpler. * time/time.h, bits/time.h, sysdeps/unix/sysv/linux/bits/time.h: Remove all logic conditional on __need macros. Move all the conditionally defined types to their own headers... * time/bits/types/clock_t.h: Define clock_t here. * time/bits/types/clockid_t.h: Define clockid_t here. * time/bits/types/struct_itimerspec.h: Define struct itimerspec here. * time/bits/types/struct_timespec.h: Define struct timespec here. * time/bits/types/struct_timeval.h: Define struct timeval here. * time/bits/types/struct_tm.h: Define struct tm here. * time/bits/types/time_t.h: Define time_t here. * time/bits/types/timer_t.h: Define timer_t here. * time/Makefile: Install the new headers. * bits/resource.h, io/fcntl.h, io/sys/poll.h, io/sys/stat.h * io/utime.h, misc/sys/select.h, posix/sched.h, posix/sys/times.h * posix/sys/types.h, resolv/netdb.h, rt/aio.h, rt/mqueue.h * signal/signal.h, pthread/semaphore.h, sysdeps/nptl/pthread.h * sysdeps/unix/sysv/linux/alpha/bits/resource.h * sysdeps/unix/sysv/linux/alpha/sys/acct.h * sysdeps/unix/sysv/linux/bits/resource.h * sysdeps/unix/sysv/linux/bits/timex.h * sysdeps/unix/sysv/linux/mips/bits/resource.h * sysdeps/unix/sysv/linux/net/ppp_defs.h * sysdeps/unix/sysv/linux/sparc/bits/resource.h * sysdeps/unix/sysv/linux/sys/acct.h * sysdeps/unix/sysv/linux/sys/timerfd.h * sysvipc/sys/msg.h, sysvipc/sys/sem.h, sysvipc/sys/shm.h * time/sys/time.h, time/sys/timeb.h Use the new bits/types headers. * include/time.h: Remove __need logic. * include/bits/time.h * include/bits/types/clock_t.h, include/bits/types/clockid_t.h * include/bits/types/time_t.h, include/bits/types/timer_t.h * include/bits/types/struct_itimerspec.h * include/bits/types/struct_timespec.h * include/bits/types/struct_timeval.h * include/bits/types/struct_tm.h: New wrapper headers. |

Remove the ptw-% patterns
Nothing depends on the PTW macro anymore, so the mechanism to define PTW for recompliations of libc routines is no longer needed. The source files are still recompiled for the nptl directory, just without the “ptw-” prefix. (Reducing the number of pattern rules in sysd-rules is critical for improving make performance.) |

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).

Add fetestexceptflag.
TS 18661-1 defines an fetestexceptflag function to test the exception state saved in an fexcept_t object by fegetexceptflag. This patch implements this function for glibc. Almost all architectures save exception state in such a way that it can be directly ANDed with exception flag bits, so rather than having lots of fetestexceptflag implementations that all do the same thing, the math/ implementation is made to use this generic logic (which is also OK in the fallback case where FE_ALL_EXCEPT is zero). The only architecture that seems to need anything different is s390. (fegetexceptflag and fesetexceptflag use abbreviated filenames fgetexcptflg.c and fsetexcptflg.c. Because we are no longer concerned by 14-character filename limits, fetestexceptflag uses the obvious filename fetestexceptflag.c.) The NEWS entry is intended to be expanded along the lines given in <https://sourceware.org/ml/libc-alpha/2016-08/msg00356.html> when fegetmode and fesetmode are added.

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>.

Minimize sysdeps code involved in defining major/minor/makedev.
Presently sys/sysmacros.h is entirely defined in sysdeps. This would mean that the deprecation logic coming up in the next patch would have to be written twice (in generic/ and unix/sysv/linux/). To avoid that, hoist all but the unavoidably system-dependent logic to misc/, leaving a bits/ header behind. This also promotes the Linux-specific encoding of dev_t, which accommodates 32-bit major and minor numbers in a 64-bit dev_t, to generic, as glibc's dev_t is always 64 bits wide. The former Linux implementation used inline functions to avoid evaluating arguments more than once. After this change, all platforms use inline functions, which means that three new symbols are added to the generic ABI. (These symbols are in the user namespace, which is how they have always been on Linux. They begin with "gnu_dev_", so collisions with user code are pretty unlikely.) New ports henceforth need only provide a bits/sysmacros.h defining internal macros __SYSMACROS_{DECLARE,DEFINE}_{MAJOR,MINOR,MAKEDEV}. This is only necessary if the kernel encoding is incompatible with the now-generic encoding (for instance, it would be necessary for FreeBSD). While I was at it, I added a basic round-trip test for these functions. * sysdeps/generic/sys/sysmacros.h: Delete file. * sysdeps/unix/sysv/linux/makedev.c: Delete file. * sysdeps/unix/sysv/linux/sys/sysmacros.h: Move file ... * bits/sysmacros.h: ... here; this encoding is now the generic encoding. Now defines only the following macros: __SYSMACROS_DECLARE_MAJOR, __SYSMACROS_DEFINE_MAJOR, __SYSMACROS_DECLARE_MINOR, __SYSMACROS_DEFINE_MINOR, __SYSMACROS_DECLARE_MAKEDEV, __SYSMACROS_DEFINE_MAKEDEV. * misc/sys/sysmacros.h, misc/makedev.c: New files that use bits/sysmacros.h and the above new macros to generate the public implementations of major, minor, and makedev. * misc/tst-makedev.c: New test. * include/sys/sysmacros.h: New wrapper. * misc/Makefile (headers): Add sys/sysmacros.h, bits/sysmacros.h.

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

Revert {send,sendm,recv,recvm}msg conformance changes
After some discussion in libc-alpha about this POSIX compliance fix, I see that GLIBC should indeed revert back to previous definition of msghdr and cmsghdr and implementation of sendmsg, recvmsg, sendmmsg, recvmmsg due some reasons: * The possible issue where the syscalls wrapper add the compatibility layer is quite limited in scope and range. And kernel current also add some limits to the values on the internal msghdr and cmsghdr fields: - msghdr::msg_iovlen larger than UIO_MAXIOV (1024) returns EMSGSIZE. - msghdr::msg_controllen larger than INT_MAX returns ENOBUFS. * There is a small performance hit for recvmsg/sendmsg/recmmsg which is neglectable, but it is a big hit for sendmmsg since now instead of calling the syscall for the packed structure, GLIBC is calling multiple sendmsg. This defeat the very existence of the syscall. * It currently breaks libsanitizer build on GCC [1] (I fixed on compiler-rt). However the fix is incomplete because it does add any runtime check since libsanitizer currently does not have any facility to intercept symbols with multiple version [2]. This, along with incorret dlsym/dlvsym return for versioned symbol due another bug [3], makes hard to interpose versioned symbols. Also, current approach of fixing GCC PR#71445 leads to half-baked solutions without versioned symbol interposing. This patch basically reverts commits |

Bug 20198: quick_exit should not call destructors.
In C++11 18.5.12 says "Objects shall not be destroyed as a result of calling quick_exit." In C11 quick_exit is silent about thread object destruction. Therefore to make glibc C++ compliant we do not call any thread local destructors. A new regression test verifies the fix. I will note that C++11 18.5.3 makes it clear that C++ defines additional requirements for _Exit() to prevent it from executing destructors. Given that the point of _Exit() is to terminate the process immediately it makes sense the C and C++ should line up and avoid calling destructors. No failures. New regtest passes. |

network: recvmmsg and sendmmsg standard compliance (BZ#16919)
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively, however Linux implements it as a size_t. So for 64-bits architecture where sizeof of size_t is larger than socklen_t, both sendmmsg and recvmmsg need to adjust the mmsghdr::msg_hdr internal fields before issuing the syscall itself. This patch fixes it by operating on the padding if it the case. For recvmmsg, the most straightfoward case, only zero padding the fields is suffice. However, for sendmmsg, where adjusting the buffer is out of the contract (since it may point to a read-only data), the function is rewritten to use sendmsg instead (which from previous patch allocates a temporary msghdr to operate on). Also for 64-bit ports that requires it, a new recvmmsg and sendmmsg compat version is created (which uses size_t for both cmsghdr::cmsg_len and internal Tested on x86_64, i686, aarch64, armhf, and powerpc64le. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = socket] (sysdep_routines): Add oldrecvmmsg and oldsendmmsg. * sysdeps/unix/sysv/linux/aarch64/libc.abilist: Add recvmmsg and sendmmsg. * sysdeps/unix/sysv/linux/alpha/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist: Likewise. * sysdeps/sysv/linux/powerpc/powerpc64/libc-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/oldrecvmmsg.c: New file. * sysdeps/unix/sysv/linux/oldsendmmsg.c: Likewise. * sysdeps/unix/sysv/linux/recvmmsg.c (__recvmmsg): Adjust msghdr iovlen and controllen fields to adjust to POSIX specification. * sysdeps/unix/sysv/linux/sendmmsg.c (__sendmmsg): Likewise. |

POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively. However Linux defines it as both size_t and for 64-bit it requires some adjustments to make the functions standard compliance. This patch fixes it by creating a temporary header and zeroing the pad fields for 64-bits architecture where size of size_t exceeds the size of the int.

Fix clone (CLONE_VM) pid/tid reset (BZ#19957)
As discussed in libc-alpha [1] current clone with CLONE_VM (without CLONE_THREAD set) will reset the pthread pid/tid fields to -1. The issue is since memory is shared between the parent and child it will clobber parent's cached pid/tid leading to internal inconsistencies if the value is not restored. And even it is restored it may lead to racy conditions when between set/restore a thread might invoke pthread function that validate the pthread with INVALID_TD_P/INVALID_NOT_TERMINATED_TD_P and thus get wrong results. As stated in BZ19957, previously reports of this behaviour was close with EWONTFIX due the fact usage of clone outside glibc is tricky since glibc requires consistent internal pthread, while using clone directly may not provide it. However since now posix_spawn uses clone (CLONE_VM) to fixes various issues related to previous vfork usage this issue requires fixing. The vfork implementation also does something similar, but instead it negates and restores only the *pid* field and functions that might access its value know to handle such case (getpid, raise and pthread ones that uses INVALID_TD_P/INVALID_NOT_TERMINATED_TD_P macros that check only *tid* field). Also vfork does not call __clone directly, instead calling either __NR_vfork or __NR_clone directly. So this patch removes this clone behavior by avoiding setting the pthread pid/tid field for CLONE_VM. There is no need to check for CLONE_THREAD, since the minimum supported kernel in all architecture implies that CLONE_VM must be used with CLONE_THREAD, otherwise clone returns EINVAL. Instead of current approach of: int clone(int (*fn)(void *), void *child_stack, int flags, ...) [...] if (flags & CLONE_THREAD) goto do_syscall; pid_t new_value; if (flags & CLONE_VM) new_value = -1; else new_value = getpid (); THREAD_SETMEM (THREAD_SELF, pid, new_value); THREAD_SETMEM (THREAD_SELF, tid, new_value); do_syscall: [...] The new approach uses: int clone(int (*fn)(void *), void *child_stack, int flags, ...) [...] if (flags & CLONE_VM) goto do_syscall; pid_t new_value = getpid (); THREAD_SETMEM (THREAD_SELF, pid, new_value); THREAD_SETMEM (THREAD_SELF, tid, new_value); do_syscall: [...] It also removes the linux tst-getpid2.c test which expects the previous behavior and instead add another clone test. Tested on x86_64, i686, x32, powerpc64le, aarch64, armhf, s390, and s390x. I also did limited check on mips32 and sparc64 (using the new added test). I also got reviews from both m68k, hppa, and tile. So I presume for these architecture the patch works. The fixes for alpha, microblaze, sh, ia64, and nio2 have not been tested.

Adjust kernel-features.h defaults for socket syscalls.
This patch adjusts the defaults for kernel-features.h macros relating to availability of accept4, recvmmsg and sendmmsg. It is not intended to affect which macros end up getting defined in any configuration. At present, all architectures with syscalls for those functions need to define __ASSUME_*_SYSCALL macros; in particular, any new architecture needs its own kernel-features.h file for that purpose, though it may not otherwise need such a header. Those macros are then used together with __ASSUME_SOCKETCALL to define macros for whether the functions in question are available. This patch changes the defaults so that the syscalls are assumed to be available by default with recent-enough kernels, and it is the responsibility of architecture headers to undefine the macros if they are unavailable in supported kernels at least as recent as the version where the architecture-independent functionality was introduced. The __ASSUME_<function> macros are defaulted similarly instead of being defined based on other macros (defining based on other macros would no longer work because the #undefs appear after the generic header is included), so where the syscall being unavailable means the function is unavailable this means the architecture header has to undefine the __ASSUME_<function> macro; this only affects __ASSUME_ACCEPT4 for ia64, as other cases where the syscalls were added late enough to be relevant with current kernel version requirements are all on socketcall architectures. As a consequence, the AArch64 and Nios II kernel-features.h header files are removed, and others simplified.

posix: New Linux posix_spawn{p} implementation
This patch implements a new posix_spawn{p} implementation for Linux. The main difference is it uses the clone syscall directly with CLONE_VM and CLONE_VFORK flags and a direct allocated stack. The new stack and start function solves most the vfork limitation (possible parent clobber due stack spilling). The remaning issue are related to signal handling: 1. That no signal handlers must run in child context, to avoid corrupt parent's state. 2. Child must synchronize with parent to enforce stack deallocation and to possible return execv issues. The first one is solved by blocking all signals in child, even NPTL-internal ones (SIGCANCEL and SIGSETXID). The second issue is done by a stack allocation in parent and a synchronization with using a pipe or waitpid (in case or error). The pipe has the advantage of allowing the child signal an exec error (checked with new tst-spawn2 test). There is an inherent race condition in pipe2 usage for architectures that do not support the syscall directly. In such cases the a pipe plus fctnl is used instead and it may lead to file descriptor leak in parent (as decribed by fcntl documentation). The child process stack is allocate with a mmap with MAP_STACK flag using default architecture stack size. Although it is slower than use a stack buffer from parent, it allows some slack for the compatibility code to run scripts with no shebang (which may use a buffer with size depending of argument list count). Performance should be similar to the vfork default posix implementation and way faster than fork path (vfork on mostly linux ports are basically clone with CLONE_VM plus CLONE_VFORK). The only difference is the syscalls required for the stack allocation/deallocation. It fixes BZ#10354, BZ#14750, and BZ#18433. Tested on i386, x86_64, powerpc64le, and aarch64.

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.

Simplify the abilist format
The new format lists the version on each line, as in: VERSION SYMBOL TYPE [VALUE] This makes it easier to process the files with line-oriented tools. The abilist files were converted with this awk script: /^[^ ]/ { version = $1 } /^ / { print version, substr($0, 2) } And sorted under the "C" locale with sort. |

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.

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call __x86.get_pc_thunk.reg to load PC into reg in case there is an error, which is required for setting errno. In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT.

libio: fmemopen rewrite to POSIX compliance
This patch added a new fmemopen version, for glibc 2.22, that aims to be POSIX complaint. It fixes some long-stading glibc fmemopen issues, such as: * it changes the way fseek with SEEK_END works on fmemopen to seek relative to buffer size instead of first '\0'. This is default mode and 'b' opening mode does not change internal behavior (bz#6544). * fix apending opening mode to use as start position either first null byte of len specified in function call (bz#13152 and #13151). * remove binary option 'b' and internal different handling (bz#12836) * fix seek/SEE_END with negative values (bz#14292). A compatibility symbol is provided to with old behavior for older symbols version (2.2.5). * include/stdio.h (fmemopen): Remove hidden prototype.

nptl: Rewrite cancellation macros
This patch changes the way cancellation entrypoints are defined to instead call the macro SYSCALL_CANCEL. An usual cnacellation definition is defined as: if (SINGLE_THREAD_P) return INLINE_SYSCALL (syscall, NARGS, args...) int oldtype = LIBC_CANCEL_ASYNC (); return INLINE_SYSCALL (syscall, NARGS, args...) LIBC_CANCEL_RESET (oldtype); And it is rewrited as just: SYSCALL_CANCEL (syscall, args...) The idea is to remove LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET explicit usage. Tested on i386, x86_64, powerpc32, powerpc64le, arm, and aarch64. * sysdeps/unix/sysdep.h [SYSCALL_CANCEL]: New macro: define cancellable syscalls. (SYS_ify): Add guard to no redefine it.

Fix semaphore destruction (bug 12674).
This commit fixes semaphore destruction by either using 64b atomic operations (where available), or by using two separate fields when only 32b atomic operations are available. In the latter case, we keep a conservative estimate of whether there are any waiting threads in one bit of the field that counts the number of available tokens, thus allowing sem_post to atomically both add a token and determine whether it needs to call futex_wake. See: https://sourceware.org/ml/libc-alpha/2014-12/msg00155.html |

Fix libm feraiseexcept namespace (bug 17723).
Various C90 and UNIX98 libm functions call feraiseexcept, which is not in those standards. This causes linknamespace test failures - except on x86 / x86_64, where feraiseexcept is inline (for the relevant constant arguments) in bits/fenv.h. This patch fixes this by making those functions call __feraiseexcept instead. All changes are applied to all architectures rather than considering the possibility that some might not be needed in some cases (e.g. x86) as it seems most maintainable to keep architectures consistent. Where __feraiseexcept does not exist, it is added, with feraiseexcept made a weak alias; where it is a strong alias, it is made weak. libm_hidden_def / libm_hidden_proto are used with __feraiseexcept (this might in some cases improve code generation for existing calls to __feraiseexcept in some code on some architectures). Where there are dummy feraiseexcept macros (on architectures without floating-point exceptions support, to avoid compile errors from references to undefined FE_* macros), corresponding dummy __feraiseexcept macros are added. And on x86, to ensure __feraiseexcept calls still get inlined, the inline function in bits/fenv.h is refactored so that most of it can be reused in an inline __feraiseexcept in a separate include/bits/fenv.h. Calls are changed in C90/UNIX98 functions, but generally not in functions missing from those standards. They are also changed in libc_fe* functions (on the basis that those might be used in any libm function), and in feupdateenv (on the same basis - may be used, via default libc_*, in any libm function - of course feupdateenv will need changing to __feupdateenv in a subsequent patch to make that fully namespace-clean). No __feraiseexcept is added corresponding to the feraiseexcept in powerpc bits/fenvinline.h, because that macro definition is conditional on !defined __NO_MATH_INLINES, and glibc libm is built with -D__NO_MATH_INLINES, so changing internal calls to use __feraiseexcept should make no difference. Tested for x86_64 (testsuite; the only change in disassembly of installed shared libraries is a slight code reordering in clog10, of no apparent significance). Also tested for MIPS, where (in the configuration tested) it eliminates math.h linknamespace failures for n32 and n64 (some for o32 remain because of other issues). [BZ #17723] * include/fenv.h (__feraiseexcept): Use libm_hidden_proto. * math/fraiseexcpt.c (__feraiseexcept): Use libm_hidden_def. * sysdeps/aarch64/fpu/fraiseexcpt.c (feraiseexcept): Rename to __feraiseexcept and define as weak alias of __feraiseexcept.

Fix __get_nprocs fgets_unlocked namespace (bug 17582).
__get_nprocs is called from malloc code, but calls fgets_unlocked, which is not an ISO C or POSIX function. This patch fixes it to call a new __fgets_unlocked name instead. Note: there are various other uses of fgets_unlocked in glibc's libraries, and I haven't yet investigated which others might also be problematic (called directly or indirectly from standard functions) and so need to change to use __fgets_unlocked. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17582] * libio/iofgets.c [weak_alias && !_IO_MTSAFE_IO] (__fgets_unlocked): Add alias of _IO_fgets. Use libc_hidden_def. * libio/iofgets_u.c (fgets_unlocked): Rename to __fgets_unlocked and define as weak alias of __fgets_unlocked. Use libc_hidden_weak.

Run check-localpltk/textrel/execstack over ld.so.
For maximum paranoia we run ld.so through the normal set of tests for all of the shared libraries. This includes running ld.so through check-localplt, check-textrel, and check-execstack. While none of these should trigger any failures given the way ld.so is built, it might possibly fail if a developer does something wrong. This paranoia was triggered by a discussion over the use of __strcpy vs. strcpy [1] and if the symbol could leak and use the libc.so version. The check-localplt test fails right away because localplt.data needs updating for all arches. By default we add 6 new symbols: __tls_get_addr, __libc_memalign, malloc, calloc, realloc and free. Other machines like i386, power, and s390 require some different symbol sets e.g. ___tls_get_addr vs. __tls_get_addr for i386.

Remove __libc_creat function name.
glibc has lots of __libc_* function names that no longer serve any purpose (are not used for any calls or exported at a public symbol version). This patch removes __libc_creat. It has the effect of creat becoming a strong symbol instead of a weak symbol in various cases, but that's fine; in shared libraries it doesn't matter at all, while for static linking the only other symbol sometimes defined in the same object is creat64, and whenever creat64 is a reserved name so is creat. Other such cases of unnecessary __libc_* symbols are expected to be dealt with in separate patches over time. Tested for x86_64 (testsuite, and that the disassembly of installed shared libraries is unchanged by the patch). * include/fcntl.h (__libc_creat): Remove declaration. * io/creat.c (__libc_creat): Rename to creat. (creat): Do not define as alias. * sysdeps/unix/sysv/linux/alpha/creat.c (creat64): Define as alias of creat instead of __libc_creat. * sysdeps/unix/sysv/linux/generic/creat.c (__libc_creat): Rename to creat.

Remove configuration name patterns from shlib-versions.
This patch removes the first column (patterns matching configuration names) from shlib-versions, leaving shlib-versions entry selection based purely on sysdeps directories. An implication of this removal is that the default for any non-Linux ports using NPTL will be the same SONAMEs for NPTL libraries as for Linux (as those defaults, previously limited to .*-.*-linux.*, are left in nptl/shlib-versions and nptl_db/shlib-versions). Special host_os handling in configure.ac that was purely for shlib-versions is removed. (The host_os setting is still used for libc-abis - see <https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding that - but no entries there are affected by this change.) Tested on x86_64 and x86 that the installed shared libraries are unchanged by this patch. * scripts/soversions.awk: Do not handle configuration names. * Makeconfig ($(common-objpfx)soversions.i): Do not pass cpu, vendor and os variables to soversions.awk. * configure.ac: Do not modify gnu-* host_os. * configure: Regenerated * shlib-versions: Remove first column with configuration names. * nptl/shlib-versions: Likewise. * nptl_db/shlib-versions: Likewise. * sysdeps/hppa/shlib-versions: Likewise. * sysdeps/m68k/shlib-versions: Likewise. * sysdeps/mach/hurd/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/aarch64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/alpha/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/arm/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/hppa/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/ia64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/microblaze/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/mips/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sh/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/tile/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/shlib-versions: Likewise. libidn/ChangeLog: * shlib-versions: Remove first column with configuration names. |

Move architecture shlib-versions files to Linux-specific directories.
Various architectures have files such as sysdeps/<arch>/shlib-versions whose contents are in fact entirely Linux-specific, relating only to the symbol / shared library versions for the port to Linux on that architecture, when any future port to a different OS on that architecture would use the symbol version of the glibc release it goes in, as standard for new ports. This patch moves such files under sysdeps/unix/sysv/linux/, merging in the contents of sysdeps/<arch>/nptl/shlib-versions in the process. The only bits not moved are those relating to libgcc_s versions, which don't appear OS-specific in the same way that glibc's symbol versions so. It deliberately does not change the regular expressions given for matching configurations in each file; some match only Linux although not Linux-specific, or match other OSes although Linux-specific. It is with a view to at least the following further cleanups: * Move architecture-specific content from the toplevel shlib-versions and nptl/shlib-versions into sysdeps shlib-versions files, so eliminating another difference between ex-ports and non-ex-ports architectures. * Likewise, for OS-specific content in shlib-versions files. * At that point, the first field in shlib-versions files (the regular expression matching a configuration triplet) should be redundant, so eliminate that field and leave shlib-versions selection working purely on a sysdeps basis (with limited use of %ifdef in shlib-versions files when needed) rather than having its own separate mechanism to select what configuration information is relevant. * Move the build of gnu/lib-names.h to a similar mechanism to that used for gnu/stubs.h (each library build installing a version of the header specifically for that build), so we can eliminate the duplication of soname information in the makefiles and get it purely from shlib-versions files again. There may be other cleanups possible as well (in particular, I'm not sure that all cases where the same "Earliest symbol set" information is repeated for many different libraries actually should need to repeat it rather than specifying it just once for DEFAULT for the given configuration, and separately specifying any non-default choices of soname). Tested x86_64 that the installed shared libraries are unchanged by this patch. * sysdeps/aarch64/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/aarch64/shlib-versions: ... here. * sysdeps/alpha/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/alpha/shlib-versions: ... here. * sysdeps/arm/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/arm/shlib-versions: ... here. * sysdeps/hppa/shlib-versions: Move all contents except for libgcc_s entry to ... * sysdeps/unix/sysv/linux/hppa/shlib-versions: ... here.
