* 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.

| | | | | | | | | 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

* nptl: Move pthread_mutexattr_destroy 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_kill_other_threads_np compatibility symbol into libcFlorian Weimer2021-04-2261-29/+32
| | | | And stop including the function for new architectures.
* 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.

* nptl: Move part of TCB initialization from libpthread to __tls_init_tpFlorian Weimer2021-04-211-29/+0
| | | | | | | | | | | | | | | | | | | This initalization should only happen once for the main thread's TCB. At present, auditors can achieve this by not linking against libpthread. If libpthread becomes part of libc, doing this initialization in libc would happen for every audit namespace, or too late (if it happens from the main libc only). That's why moving this code into ld.so seems the right thing to do, right after the TCB initialization. For !__ASSUME_SET_ROBUST_LIST ports, this also moves the symbol __set_robust_list_avail into ld.so, as __nptl_set_robust_list_avail. It also turned into a proper boolean flag. Inline the __pthread_initialize_pids function because it seems no longer useful as a separate function. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

| | | | | | | | | | | | | | The pthread_exit symbol was moved using scripts/move-symbol-to-libc.py. No new symbol version is needed because there was a forwarder. The new tests nptl/tst-pthread_exit-nothreads and nptl/tst-pthread_exit-nothreads-static exercise the scenario that pthread_exit is called without libpthread having been linked in. This is not possible for the generic code, so these tests do not live in sysdeps/pthread for now. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move __pthread_unwind_next into libcFlorian Weimer2021-04-2163-56/+65
| | | | | | | | | | | | | | | | | | | It's necessary to stub out __libc_disable_asynccancel and __libc_enable_asynccancel via rtld-stubbed-symbols because the new direct references to the unwinder result in symbol conflicts when the rtld exception handling from libc is linked in during the construction of librtld.map. unwind-forcedunwind.c is merged into unwind-resume.c. libc now needs the functions that were previously only used in libpthread. The GLIBC_PRIVATE exports of __libc_longjmp and __libc_siglongjmp are no longer needed, so switch them to hidden symbols.
