* nptl: Move pthread_getname_np into libcFlorian Weimer2021-05-173-6/+13
| | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. 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 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.

| | | | | | | | | | | | 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.
