* nptl: Add missing __pthread_cond_wait alias in static buildsFlorian Weimer2021-05-191-0/+3
| | | | | | | Fixes commit cf3fff1c195f859ba949a7ad86d4fca70bd99740 ("nptl: Move cnd_wait into libc"). Reviewed-by: Jonathan Nieder <jrnieder@gmail.com>
* nptl: Move pthread_sigqueue into libcFlorian Weimer2021-05-174-5/+19
| | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. The GLIBC_2.11 version is now empty, so add a placeholder symbol. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move pthread_setschedprio into libcFlorian Weimer2021-05-174-6/+19
| | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. The GLIBC_2.3.4 version is now empty, so add a placeholder symbol. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move pthread_setname_np into libcFlorian Weimer2021-05-174-4/+21
| | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. Add __libpthread_version_placeholder@@GLIBC_2.12 for the targets that need it. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* nptl: Move pthread_getcpuclockid into libcFlorian Weimer2021-05-174-7/+23
| | | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. __libpthread_version_placeholder@@GLIBC_2.2 is needed by this change; the Versions entry for GLIBC_2.2 in libpthread had leftover symbols due to an error in a previous conflict resolution. The condition for the placeholder symbol is complicated because some architectures have earlier symbols at the GLIBC_2.2 symbol versions, so the placeholder is not required there (yet).

* nptl: Move pthread_getattr_default_np into libcFlorian Weimer2021-05-175-6/+26
| | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. A new placeholder symbol __libpthread_version_placeholder@GLIBC_2.18 is needed to keep the GLIBC_2.18 symbol version in libpthread. The __pthread_getattr_default_np@@GLIBC_PRIVATE export is used from pthread_create. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move __nptl_create_event, __nptl_death_event into libcFlorian Weimer2021-05-174-5/+7
| | | | | | | | In libthread_db, use the exported GLIBC_PRIVATE symbols directly instead of relying on _thread_db_* variables in libpthread (which used to be created by the DB_FUNCTION macros). Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move __nptl_initial_report_events into ld.so/startup codeFlorian Weimer2021-05-173-12/+6
| | | | | | | | | | | | The initialization of the report_events TCB field is now performed in __tls_init_tp instead of __pthread_initialize_minimal_internal (in libpthread). The events interface is difficult to test because GDB stopped using it in 2015. The td_thr_get_info change to ignore lookup issues is enough to support GDB with this change.

* nptl: Fix tst-pthread-gdb-attach for ptrace_scope equal 1Adhemerval Zanella2021-05-141-17/+39
| | | | | | | | | This is similar to the fix for elf/tst-pldd (2f9046fb059e94fe25): it checks ptrace_scope value (values higher than 2 are too restrictive to allow the test to run) and it rearranges the spawned processes to make the target process the gdb child. Checked on x86_64-linux-gnu with ptrace_scope set to 1.
* nptl: Move pthread_getconcurrency, pthread_setconcurrency into libcFlorian Weimer2021-05-114-8/+24
| | | | | | | | The symbols were moved using scripts/move-symbol-to-libc.py, in one commit due to their dependency on the internal __concurrency_level variable. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* nptl: Move pthread_attr_setstacksize into libcFlorian Weimer2021-05-113-11/+19
| | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. It is necessary to arrange for a __libpthread_version_placeholder@GLIBC_2.6 on some of the powerpc targets. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* nptl: Move stack cache management, __libpthread_freeres into libcFlorian Weimer2021-05-119-153/+202
| | | | | | | | | | | | | This replaces the FREE_P macro with the __nptl_stack_in_use inline function. stack_list_del is renamed to __nptl_stack_list_del, stack_list_add to __nptl_stack_list_add, __deallocate_stack to __nptl_deallocate_stack, free_stacks to __nptl_free_stacks. It is convenient to move __libpthread_freeres into libc at the same time. This removes the temporary __default_pthread_attr_freeres export and restores full freeres coverage for __default_pthread_attr. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move pthread_setattr_default_np into libcFlorian Weimer2021-05-114-6/+16
| | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. The export of __default_pthread_attr_freeres is temporary. There is a minor regression in freeres coverage because in the dynamic case, __default_pthread_attr_freeres is no longer called if libpthread is not linked in.
