* posix: Consolidate fork implementationAdhemerval Zanella2021-06-243-14/+139
| | | | | | | | | | | | | | | | The Linux nptl implementation is used as base for generic fork implementation to handle the internal locks and mutexes. The system specific bits are moved a new internal _Fork symbol. (This new implementation will be used to provide a async-signal-safe _Fork now that POSIX has clarified that fork might not be async-signal-safe [1]). For Hurd it means that the __nss_database_fork_prepare_parent and __nss_database_fork_subprocess will be run in a slight different order. [1] https://austingroupbugs.net/view.php?id=62

* y2038: Add support for 64-bit time on legacy ABIsAdhemerval Zanella2021-06-152-1/+30

The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time.

* linux: Use sched_getaffinity for __get_nprocs (BZ #27645)Adhemerval Zanella2021-05-071-0/+1
| | | | | | | | Both the sysfs and procfs parsing (through GET_NPROCS_PARSER) are removed in favor the syscall. The initial scratch buffer should fit to most of the common usage (1024 bytes with maps to 8192 CPUs). Checked on x86_64-linux-gnu and aarch64-linux-gnu.
* Remove architecture specific sched_cpucount optimizationsAdhemerval Zanella2021-05-071-26/+14
| | | | | | | | | | | | | | And replace the generic algorithm with the Brian Kernighan's one. GCC optimize it with popcnt if the architecture supports, so there is no need to add the extra POPCNT define to enable it. This is really a micro-optimization that only adds complexity: recent ABIs already support it (x86-64-v2 or power64le) and it simplifies the code for internal usage, since i686 does not allow an internal iFUNC call. Checked on x86_64-linux-gnu, aarch64-linux-gnu, and powerpc64le-linux-gnu.
* Annotate additional APIs with GCC attribute access.Martin Sebor2021-05-062-8/+17
| | | | | | | | | | | | | | | | This change continues the improvements to compile-time out of bounds checking by decorating more APIs with either attribute access, or by explicitly providing the array bound in APIs such as tmpnam() that expect arrays of some minimum size as arguments. (The latter feature is new in GCC 11.) The only effects of the attribute and/or the array bound is to check and diagnose calls to the functions that fail to provide a sufficient number of elements, and the definitions of the functions that access elements outside the specified bounds. (There is no interplay with _FORTIFY_SOURCE here yet.) Tested with GCC 7 through 11 on x86_64-linux.

| | | | | | | | | | | | | | | | Gnulib has added the proposed fix with aed23714d60 (done in 2005), but recently with a glibc merge with 67306f6 (done in 2020 with sync back) it has fallback to old semantic to return -1 on in case of failure. From gnulib developer feedback it was an oversight. Although the full fix for BZ #14185 would require to rewrite fnmatch implementation to use mbrtowc instead of mbsrtowcs on the full input, this mitigate the issue and it has been used by gnulib for a long time. This patch also removes the alloca usage on the string convertion to wide characters before calling the internal function. Checked on x86_64-linux-gnu.

* linux: Require /dev/shm as the shared memory file systemFlorian Weimer2021-02-083-1/+49
| | | | | | | | | | | | | | | | | | | | | Previously, glibc would pick an arbitrary tmpfs file system from /proc/mounts if /dev/shm was not available. This could lead to an unsuitable file system being picked for the backing storage for shm_open, sem_open, and related functions. This patch introduces a new function, __shm_get_name, which builds the file name under the appropriate (now hard-coded) directory. It is called from the various shm_* and sem_* function. Unlike the SHM_GET_NAME macro it replaces, the callers handle the return values and errno updates. shm-directory.c is moved directly into the posix subdirectory because it can be implemented directly using POSIX functionality. It resides in libc because it is needed by both librt and nptl/htl. In the sem_open implementation, tmpfname is initialized directly from a string constant. This happens to remove one alloca call. Checked on x86_64-linux-gnu.

* sysconf: Add _SC_MINSIGSTKSZ/_SC_SIGSTKSZ [BZ #20305]H.J. Lu2021-02-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add _SC_MINSIGSTKSZ for the minimum signal stack size derived from AT_MINSIGSTKSZ, which is the minimum number of bytes of free stack space required in order to gurantee successful, non-nested handling of a single signal whose handler is an empty function, and _SC_SIGSTKSZ which is the suggested minimum number of bytes of stack space required for a signal stack. If AT_MINSIGSTKSZ isn't available, sysconf (_SC_MINSIGSTKSZ) returns MINSIGSTKSZ. On Linux/x86 with XSAVE, the signal frame used by kernel is composed of the following areas and laid out as: ------------------------------ | alignment padding | ------------------------------ | xsave buffer | ------------------------------ | fsave header (32-bit only) | ------------------------------ | siginfo + ucontext | ------------------------------ Compute AT_MINSIGSTKSZ value as size of xsave buffer + size of fsave header (32-bit only) + size of siginfo and ucontext + alignment padding. If _SC_SIGSTKSZ_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are redefined as /* Default stack size for a signal handler: sysconf (SC_SIGSTKSZ). */ # undef SIGSTKSZ # define SIGSTKSZ sysconf (_SC_SIGSTKSZ) /* Minimum stack size for a signal handler: SIGSTKSZ. */ # undef MINSIGSTKSZ # define MINSIGSTKSZ SIGSTKSZ Compilation will fail if the source assumes constant MINSIGSTKSZ or SIGSTKSZ. The reason for not simply increasing the kernel's MINSIGSTKSZ #define (apart from the fact that it is rarely used, due to glibc's shadowing definitions) was that userspace binaries will have baked in the old value of the constant and may be making assumptions about it. For example, the type (char [MINSIGSTKSZ]) changes if this #define changes. This could be a problem if an newly built library tries to memcpy() or dump such an object defined by and old binary. Bounds-checking and the stack sizes passed to things like sigaltstack() and makecontext() could similarly go wrong.

Please remember to include 2021 in the dates for any new files added in future (which means updating any existing uncommitted patches you have that add new files to use the new copyright dates in them).

| | | | | | | | | | | | | | | | | | | | | | | | | | | The tests posix/bug-ga2-mem and resolv/mtrace-tst-leaks2 are failing on fedora 33 as mtrace reports memory leaks. The /etc/nsswitch.conf differs between Fedora 32: hosts: files dns myhostname Fedora 33: hosts: files resolve [!UNAVAIL=return] myhostname dns Therefore /lib64/libnss_resolve.so.2 (from systemd) and the dependencies libgcc_s.so.1 and libpthread.so.0 are loaded. Usually all malloc'ed resources from getaddrinfo / gethostbyname are freed and the libraries are dlclose'd in nss/nsswitch.c:libc_freeres_fn (free_mem). Unfortunately, /lib64/libnss_resolve.so.2 is marked with DF_1_NODELETE. As this library is not unmapped, you'll see "Memory not freed". Therefore those tests are now only relying on libnss_files.so by making them test-container tests and providing the required configuration files. By moving the tests to tests-container, those are now running with "make check". Therefore the mtrace part of the tests are also moved from "make xcheck" to "make check". bug-ga2.c is now using test-driver.c in order to support WAIT_FOR_DEBUGGER environment variable.
* Remove tls.h inclusion from internal errno.hAdhemerval Zanella2020-11-134-1/+4
| | | | | | | | | | | | The tls.h inclusion is not really required and limits possible definition on more arch specific headers. This is a cleanup to allow inline functions on sysdep.h, more specifically on i386 and ia64 which requires to access some tls definitions its own. No semantic changes expected, checked with a build against all affected ABIs.

* Fix handling of collating symbols in fnmatch (bug 26620)Andreas Schwab2020-09-163-3/+41
| | | | | | The variable idx contains the index into the extra array, whereas wextra points into the extra array at this index, containing the length of the following collating sequence in the wide character representation.
* Remove internal usage of extensible stat functionsAdhemerval Zanella2020-09-111-7/+0
| | | | | | | | | | | | It replaces the internal usage of __{f,l}xstat{at}{64} with the __{f,l}stat{at}{64}. It should not change the generate code since sys/stat.h explicit defines redirections to internal calls back to xstat* symbols. Checked with a build for all affected ABIs. I also check on x86_64-linux-gnu and i686-linux-gnu. Reviewed-by: Lukasz Majewski <lukma@denx.de>
* Copy regex_internal.h from GnulibPaul Eggert2020-08-041-2/+1
| | | | | | | | | | | Sync this file from Gnulib, thus incorporating the following fix for a bug with regexps with 16 or more subexpressions: * posix/regex_internal.h (struct re_backref_cache_entry): Use bitset_word_t as the type of eps_reachable_subexps_map, instead of unsigned short int. This fixes a bug I introduced to glibc in 2005-09-28T17:33:18Z!drepper@redhat.com (glibc commit 2c05d33f90861d074dc12808dafbde30f487b1a0, BZ #1302). Remove unused member 'unused'.
* Copy regex BITSET_WORD_BITS porting from GnulibPaul Eggert2020-08-042-30/+22
| | | | | | | | * posix/regex.c (__STDC_WANT_IEC_60559_BFP_EXT__): Define, for ULONG_WIDTH. This syncs regex.c from Gnujlib. * posix/regex_internal.h (ULONG_WIDTH): Use a more-portable fallback, from Gnulib. (BITSET_WORD_BITS): Now defined in terms of ULONG_WIDTH.
* Sync regex.h from GnulibPaul Eggert2020-08-041-2/+0
| | | | | * posix/regex.h: Remove an ‘#ifndef _CRAY’ that hasn’t been needed for years in Gnulib (and was needed only because of Gnulib).
