* linux: Add close_rangeAdhemerval Zanella2021-07-0837-1/+362
| | | | | | | | | | It was added on Linux 5.9 (278a5fbaed89) with CLOSE_RANGE_CLOEXEC added on 5.11 (582f1fb6b721f). Although FreeBSD has added the same syscall, this only adds the symbol on Linux ports. This syscall is required to provided a fail-safe way to implement the closefrom symbol (BZ #10353). Checked on x86_64-linux-gnu and i686-linux-gnu on kernel 5.11 and 4.15.
* libio: Replace internal _IO_getdelim symbol with __getdelimFlorian Weimer2021-07-071-1/+1
| | | | | | | __getdelim is exported, _IO_getdelim is not. Add a hidden prototype for __getdelim. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* Update kernel version to 5.13 in tst-mman-consts.pyJoseph Myers2021-07-071-1/+1
| | | | | | | | This patch updates the kernel version in the test tst-mman-consts.py to 5.13. (There are no new MAP_* constants covered by this test in 5.13 that need any other header changes.) Tested with build-many-glibcs.py.
* nptl: Remove GLIBC_2.34 versions of __pthread_mutex_lock, __pthread_mutex_unlockFlorian Weimer2021-07-0732-64/+0
| | | | | | | | Now that there are no internal users anymore, these new symbol versions can be removed from the public ABI. The compatibility symbols remain. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* linux: Fix setsockopt fallbackAdhemerval Zanella2021-07-061-1/+3
| | | | | | | The final 2 arguments for SO_TIMESTAMP/SO_TIMESTAMPNS are being set wrongly. Checked on x86_64-linux-gnu and i686-linux-gnu.
* linux: Use the expected size for SO_TIMESTAMP{NS} convertionAdhemerval Zanella2021-07-061-2/+5
| | | | | | | Kernel returns 32-bit values for COMPAT_SO_TIMESTAMP{NS}_OLD, not 64-bit values. Checked on x86_64-linux-gnu and i686-linux-gnu.
* linux: Consolidate Linux setsockopt implementationAdhemerval Zanella2021-07-0615-14/+5
| | | | | | | | | | | | | | | | This patch consolidates the setsockopt implementation on sysdeps/unix/sysv/linux/getsockopt.c. The changes are: 1. Remove it from auto-generation syscalls.list on all architectures. 2. Add __ASSUME_SETSOCKOPT_SYSCALL as default and undef if for specific kernel versions on some architectures. This also fix a potential issue where 32-bit time_t ABI should use the linux setsockopt which overrides the underlying SO_* constants used for socket timestamping for _TIME_BITS=64. Checked on x86_64-linux-gnu and i686-linux-gnu.

* resolv: Move libanl into libc (if libpthread is in libc)Florian Weimer2021-07-0264-145/+307
| | | | | | | | | | The symbols gai_cancel, gai_error, gai_suspend, getaddrinfo_a, __gai_suspend_time64 were moved using scripts/move-symbol-to-libc.py. For Hurd (which remains !PTHREAD_IN_LIBC), a few #define redirects had to be added because several pthread functions are not available under __. (Linux uses __ prefixes for most hidden aliases, and has to in some cases to avoid linknamespace issues.)
* Update syscall lists for Linux 5.13Joseph Myers2021-07-0126-2/+80
| | | | | | | | | Linux 5.13 has three new syscalls (landlock_create_ruleset, landlock_add_rule, landlock_restrict_self). Update syscall-names.list and regenerate the arch-syscall.h headers with build-many-glibcs.py update-syscalls. Tested with build-many-glibcs.py.
* Fix extra PLT reference in libc.so due to __glob64_time64 if build with gcc ↵Stefan Liebler2021-07-011-0/+1
| | | | | | | | | | | | | | | | 7.5 on 32bit. Starting with recent commit 84f7ce84474c1648ce96884f1c91ca7b97ca3fc2 "posix: Add glob64 with 64-bit time_t support", elf/check-localplt fails due to extra PLT reference __glob64_time64 in __glob64_time64 itself. This is observable with gcc 7.5 on x86_64 with -m32 or s390x with -m31. E.g. if build with gcc 10, gcc is generating a call to __glob64_time64.localalias. This patch is adding a hidden version of __glob64_time64 in the same way as for __globfree64_time64.
* Linux: Avoid calling malloc indirectly from __get_nprocsFlorian Weimer2021-06-301-26/+57

* login: Move libutil into libcFlorian Weimer2021-06-3066-188/+454
| | | | | | | | | | | | | | | | The symbols forkpty, login, login_tty, logout, logwtmp, openpty were moved using scripts/move-symbol-to-libc.py. This is a single commit because most of the symbols are tied together via forkpty, for example. Several changes to use hidden prototypes are needed. This commit also updates pseudoterminal terminology on modified lines. For 390 (31-bit), this commit follows the existing style for the compat symbol version creation.

* posix: Add _Fork [BZ #4737]Adhemerval Zanella2021-06-2832-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | Austin Group issue 62 [1] dropped the async-signal-safe requirement for fork and provided a async-signal-safe _Fork replacement that does not run the atfork handlers. It will be included in the next POSIX standard. It allow to close a long standing issue to make fork AS-safe (BZ#4737). As indicated on the bug, besides the internal lock for the atfork handlers itself; there is no guarantee that the handlers itself will not introduce more AS-safe issues. The idea is synchronize fork with the required internal locks to allow children in multithread processes to use mostly of standard function (even though POSIX states only AS-safe function should be used). On signal handles, _Fork should be used intead and only AS-safe functions should be used. For testing, the new tst-_Fork only check basic usage. I also added a new tst-mallocfork3 which uses the same strategy to check for deadlock of tst-mallocfork2 but using threads instead of subprocesses (and it does deadlock if it replaces _Fork with fork).

The way the ABI intransition is implemented is changed with this commit: the implementation is now consolidated in one file with a TIMER_T_WAS_INT_COMPAT check. The shared librt is now empty, so this commit adds a placeholder symbol at the base version, GLIBC_2.2, and potentially at the GLIBC_2.3.3 version as well (the leftover from the int/timer_t ABI transition).
