* nptl: Replace pthread_sigqueue implementation with Linux oneFlorian Weimer2021-05-111-4/+38

* linux: Move funlockfile/_IO_funlockfile into libcAdhemerval Zanella2021-05-101-1/+0
| | | | | | | | | | The nptl version is used as default, since now with symbol always present the single-thread optimization is tricky. Hurd is not change, it is used it own lock scheme (which call _cthreads_funlockfile). Checked on x86_64-linux-gnu.

* Linux: Move __reclaim_stacks into the fork implementation in libcFlorian Weimer2021-05-104-119/+0
| | | | | | | As a result, __libc_pthread_init is no longer needed. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Move __default_pthread_attr, __default_pthread_attr_lock into libcFlorian Weimer2021-05-104-6/+14
| | | | | | | | The GLIBC_PRIVATE exports for these symbols are expected to be temporary. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Simplify resetting the in-flight stack in __reclaim_stacksFlorian Weimer2021-05-101-3/+3

* nptl: Move changing of stack permissions into ld.soFlorian Weimer2021-05-103-68/+6
| | | | | | | | | All the stack lists are now in _rtld_global, so it is possible to change stack permissions directly from there, instead of calling into libpthread to do the change. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Simplify the change_stack_perm calling conventionFlorian Weimer2021-05-101-24/+5
| | | | | | | | Only ia64 needs the page mask, and it is straightforward to compute the value within the function itself. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Move more stack management variables into _rtld_globalFlorian Weimer2021-05-101-30/+21
| | | | | | | | | | | | Permissions of the cached stacks may have to be updated if an object is loaded that requires executable stacks, so the dynamic loader needs to know about these cached stacks. The move of in_flight_stack and stack_cache_actsize is a requirement for merging __reclaim_stacks into the fork implementation in libc.

* nptl: Export __libc_multiple_threads from libc as an internal symbolFlorian Weimer2021-05-107-29/+8
| | | | | | | | This allows the elimination of the __libc_multiple_threads_ptr variable in libpthread and its initialization procedure. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* elf, nptl: Resolve recursive lock implementation earlyFlorian Weimer2021-05-101-9/+0
| | | | | | | | | | | If libpthread is included in libc, it is not necessary to delay initialization of the lock/unlock function pointers until libpthread is loaded. This eliminates two unprotected function pointers from _rtld_global and removes some initialization code from libpthread.

| | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. A small adjust to the sem_unlink implementation is necessary to avoid a check-localplt failure. A placeholder symbol to keep the GLIBC_2.1.1 version alive in libpthread is added with this commit. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

| | | | | | | | | | | The symbols were moved using move-symbol-to-libc.py. Both functions are moved at the same time because they depend on internal functions in sysdeps/pthread/sem_routines.c, which are moved in this commit as well. Additional hidden prototypes are required to avoid check-localplt failures. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* nptl: Consolidate async cancel enable/disable implementation in libcFlorian Weimer2021-05-056-33/+7
| | | | | | | | | | | | | | Previously, the source file nptl/cancellation.c was compiled multiple times, for libc, libpthread, librt. This commit switches to a single implementation, with new __pthread_enable_asynccancel@@GLIBC_PRIVATE, __pthread_disable_asynccancel@@GLIBC_PRIVATE exports. The almost-unused CANCEL_ASYNC and CANCEL_RESET macros are replaced by LIBC_CANCEL_ASYNC and LIBC_CANCEL_ASYNC macros. They call the __pthread_* functions unconditionally now. The macros are still needed because shared code uses them; Hurd has different definitions. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* elf, nptl: Initialize static TLS directly in ld.soFlorian Weimer2021-05-053-39/+0
| | | | | | | | | | The stack list is available in ld.so since commit 1daccf403b1bd86370eb94edca794dc106d02039 ("nptl: Move stack list variables into _rtld_global"), so it's possible to walk the stack list directly in ld.so and perform the initialization there. This eliminates an unprotected function pointer from _rtld_global and reduces the libpthread initialization code.
