* nptl: Move mtx_timedlock into libcFlorian Weimer2021-05-0363-37/+79
| | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. The __pthread_mutex_timedlock@@GLIBC_PRIVATE export is no longer needed, so it is removed with this commit. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Move mtx_lock into libcFlorian Weimer2021-05-0361-29/+64
| | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. __pthread_mutex_lock@GLIBC_2.34 is not removed in this commit because it is still used from nptl/nptl-init.c. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Move mtx_init into libcFlorian Weimer2021-05-0361-125/+64
| | | | | | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. The calls to __pthread_mutex_init, __pthread_mutexattr_init, __pthread_mutexattr_settype are now private and no longer need to be exported. This allows the removal of the newly added GLIBC_2.34 symbol versions for those functions. Also clean up some weak declarations in <libc-lockP.h> for these functions. They are not needed and potentially incorrect for static linking of mtx_init. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Move mtx_destroy into libcFlorian Weimer2021-05-0361-61/+64
| | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. The __pthread_mutex_destroy@@GLIBC_2.34 symbol is no longer neded because this commit makes __pthread_mutex_destroy@GLIBC_2.0 a compatibility symbol, so remove the new symbol version.

* nptl: Move call_once into libcFlorian Weimer2021-05-0361-61/+64
| | | | | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. This change also turns __pthread_once into a compatibility symbol because after the call_once move, an internal call to __pthread_once can be used. This an adjustment to __libc_once: Outside libc (e.g., in nscd), it has to call pthread_once. With __pthread_once as a compatibility symbol, it is no longer to add a new GLIBC_2.34 version after the move from libpthread, and this commit removes the new __pthread_once@@GLIBC_2.34 version.

* Update kernel version to 5.12 in tst-mman-consts.py.Joseph Myers2021-04-291-1/+1
| | | | | | | | This patch updates the kernel version in the test tst-mman-consts.py to 5.12. (There are no new MAP_* constants covered by this test in 5.12 that need any other header changes.) Tested with build-many-glibcs.py.
* Update syscall lists for Linux 5.12.Joseph Myers2021-04-2826-2/+28
| | | | | | | | Linux 5.12 has one new syscall, mount_setattr. Update syscall-names.list and regenerate the arch-syscall.h headers with build-many-glibcs.py update-syscalls. Tested with build-many-glibcs.py.

* nptl: Move pthread_spin_init, Move pthread_spin_unlock into libcFlorian Weimer2021-04-2361-58/+128
| | | | | | | For some architectures, the two functions are aliased, so these symbols need to be moved at the same time. The symbols were moved using scripts/move-symbol-to-libc.py.

| | | | | | | | | And pthread_mutexattr_setkind_np as a compatibility symbol. __pthread_mutexattr_settype is used in mtx_init from libpthread, so this commit adds a GLIBC_2.34 symbol version for it. The symbols were moved using scripts/move-symbol-to-libc.py.

* nptl: Move pthread_mutexattr_init, __pthread_mutexattr_init into libcFlorian Weimer2021-04-2361-58/+128
| | | | | | | __pthread_mutexattr_init cannot be be made a compat symbol because it is used in mtx_init, which is still in libpthread. The symbols were moved using scripts/move-symbol-to-libc.py.
* nptl: Move pthread_mutexattr_gettype into libcFlorian Weimer2021-04-2361-58/+96
| | | | | | | | And pthread_mutexattr_getkind_np as a compatibility symbol. (There is no declaration in <pthread.h>, so there is no need to add an alias or a deprecation warning there.) The symbols were moved using scripts/move-symbol-to-libc.py.
* nptl: Move pthread_mutexattr_getrobust into libcFlorian Weimer2021-04-2361-58/+96

| | | | | | | And __pthread_mutexattr_destroy as a compat symbol (so no GLIBC_2.34 symbol version is added for it). The symbols were moved using scripts/move-symbol-to-libc.py.
* nptl: Move pthread_mutex_trylock, __pthread_mutex_trylock into libcFlorian Weimer2021-04-2361-58/+128
| | | | | | | | The symbols were moved using scripts/move-symbol-to-libc.py. __pthread_mutex_trylock is used to implement mtx_timedlock, which still resides in libpthread, so add a GLIBC_2.34 version for it, to match the existing GLIBC_2.0 version.
* nptl: Move pthread_mutex_timedlock, pthread_mutex_clocklock to libcFlorian Weimer2021-04-2361-58/+128
| | | | | | | The symbols were moved using scripts/move-symbol-to-libc.py. The symbol aliasing follows pthread_cond_timedwait et al. Missing hidden prototypes had to be added to nptl/pthreadP.h for consistency.
* nptl: Move pthread_mutex_setprioceiling into libcFlorian Weimer2021-04-2361-29/+64

* nptl: Move pthread_atfork compatibility symbol to libcFlorian Weimer2021-04-2233-15/+18
| | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. There is no new symbol version because of the compatibility symbol status. The __pthread_atfork reference in nptl/Versions was unused.
* nptl: Move setxid broadcast implementation into libcFlorian Weimer2021-04-211-4/+0
| | | | | | | The signal handler is exported as __nptl_setxid_sighandler, so that the libpthread initialization code can install it. This is sufficient for now because it is guarantueed to happen before the first pthread_create call.
* nptl: Move core condition variable functions into libcFlorian Weimer2021-04-2161-209/+80
| | | | | | | | | | | | | | | Onl pthread_cond_clockwait did not have a forwarder, so it needs a new symbol version. Some complications arise due to the need to supply hidden aliases, GLIBC_PRIVATE exports (for the C11 condition variable implementation that still remains in libpthread) and 64-bit time_t stubs. pthread_cond_broadcast, pthread_cond_signal, pthread_cond_timedwait, pthread_cond_wait, pthread_cond_clockwait have been moved using scripts/move-symbol-to-libc.py.

* nptl: Move core mutex functions into libcFlorian Weimer2021-04-2161-232/+256
| | | | | | | | | | | | | | This is complicated because of a second compilation of nptl/pthread_mutex_lock.c via nptl/pthread_mutex_cond_lock.c. PTHREAD_MUTEX_VERSIONS is introduced to suppress symbol versions in that case. The symbols __pthread_mutex_lock, __pthread_mutex_unlock, __pthread_mutex_init, __pthread_mutex_destroy, pthread_mutex_lock, pthread_mutex_unlock, pthread_mutex_init, pthread_mutex_destroy have been moved using scripts/move-symbol-to-libc.py.

* x86: Remove low-level lock optimizationFlorian Weimer2021-04-211-87/+0
| | | | | | | | | | | | | | | The current approach is to do this optimizations at a higher level, in generic code, so that single-threaded cases can be specifically targeted. Furthermore, using IS_IN (libc) as a compile-time indicator that all locks are private is no longer correct once process-shared lock implementations are moved into libc. The generic <lowlevellock.h> is not compatible with assembler code (obviously), so it's necessary to remove two long-unused #includes. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move rwlock functions with forwarders into libcFlorian Weimer2021-04-2161-174/+288
| | | | | | | | | | | | | | | The forwarders were only used internally, so new symbol versions are needed. All symbols are moved at once because the forwarders are no-ops if libpthread is not loaded, leading to inconsistencies in case of a partial migration. The symbols __pthread_rwlock_rdlock, __pthread_rwlock_unlock, __pthread_rwlock_wrlock, pthread_rwlock_rdlock, pthread_rwlock_unlock, pthread_rwlock_wrlock have been moved using scripts/move-symbol-to-libc.py. The __ symbol variants are turned into compat symbols, which is why they do not receive a GLIBC_2.34 version.
* nptl: Move pthread_key_delete into libc.Florian Weimer2021-04-2161-29/+64
| | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. tss_delete (still in libpthread) uses the __pthread_key_create alias, so that is now exported under GLIBC_PRIVATE.
* nptl: Move pthread_setspecific, __pthread_setspecific into libcFlorian Weimer2021-04-2161-58/+128
| | | | The symbols have been moved using scripts/move-symbol-to-libc.py.
