* dlfcn: Cleanups after -ldl is no longer requiredFlorian Weimer2021-06-031-7/+0
| | | | | | | | | | | | This commit removes the ELF constructor and internal variables from dlfcn/dlfcn.c. The file now serves the same purpose as nptl/libpthread-compat.c, so it is renamed to dlfcn/libdl-compat.c. The use of libdl-shared-only-routines ensures that libdl.a is empty. This commit adjusts the test suite not to use $(libdl). The libdl.so symbolic link is no longer installed. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* Add missing symbols to Version filesFlorian Weimer2021-06-021-0/+8
| | | | | | | | | Some symbols have explicit versioned_symbol or compat_symbol markers in the sources, but no corresponding entry in the Versions files. This presently works because the local: * directive is only applied to the base version. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Add pthread_attr_setaffinity_np failure testAdhemerval Zanella2021-05-272-0/+60
| | | | | | | | It checks whether an invalid affinity mask does return an error, similar to what sysdeps/pthread/tst-bad-schedattr.c does for pthread_attr_setschedparam. Checked on x86_64-linux-gnu.
* nptl: Move createthread to pthread_createAdhemerval Zanella2021-05-272-166/+115
| | | | | | | | The 'create_thread' function is moved to pthread_create.c. It removes the START_THREAD_DEFN and START_THREAD_SELF macros and make the lock usage more clear (no need to cross-reference multiple files). No functional change.
* nptl: Move Linux createthread to nptlAdhemerval Zanella2021-05-271-8/+116
| | | | | | git mv -f sysdeps/unix/sysv/linux/createthread.c nptl/createthread.c No functional change.
* nptl: Install SIGSETXID handler with SA_ONSTACK [BZ #27914]Florian Weimer2021-05-271-2/+5
| | | | | | | | | | | | | | The signal is sent to all threads, some of which may have switched to very small stacks. If they have also installed an alternate signal stack, SA_ONSTACK makes this work. The Go runtime needs this: runtime: C.setuid/C.setgid smashes Go stack <https://github.com/golang/go/issues/9400> Doing this for SIGCANCEL is less obviously beneficial and needs further testing.

* Linux: Remove remaining references to $(shared-thread-library)Florian Weimer2021-05-251-14/+7
| | | | | | | Since the variable expands to nothing under Linux, it is no longer necessary to clutter the makefiles with it. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Do not install libpthread.so and do not link tests with itFlorian Weimer2021-05-251-24/+5

* nptl: Remove remaining code from libpthreadFlorian Weimer2021-05-217-195/+11
| | | | | | | | | Only the placeholder compatibility symbols are left now. The __errno_location symbol was removed (moved) using scripts/move-symbol-to-libc.py. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move pthread_create, thrd_create into libcFlorian Weimer2021-05-216-26/+38
| | | | | | | | | | | | | | | | | | | The symbols were moved using scripts/move-symbol-to-libc.py. The libpthread placeholder symbols need some changes because some symbol versions have gone away completely. But __errno_location@@GLIBC_2.0 still exists, so the GLIBC_2.0 version is still there. The internal __pthread_create symbol now points to the correct function, so the sysdeps/nptl/thrd_create.c override is no longer necessary. There was an issue how the hidden alias of pthread_getattr_default_np was defined, so this commit cleans up that aspects and removes the GLIBC_PRIVATE export altogether.

* nptl: Move semi-public __pthread_get_minstack symbol into libcFlorian Weimer2021-05-215-20/+23
| | | | | | | | | No abilist updates here because it is a GLIBC_PRIVATE symbol. It's also necessary to move nptl_version into pthread_create, so that it still ends up in static binaries. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Eliminate the __static_tls_size, __static_tls_align_m1 variablesFlorian Weimer2021-05-214-59/+27
| | | | | | | | | | | | | | | | | | | Use the __nptl_tls_static_size_for_stack inline function instead, and the GLRO (dl_tls_static_align) value directly. The computation of GLRO (dl_tls_static_align) in _dl_determine_tlsoffset ensures that the alignment is at least TLS_TCB_ALIGN, which at least STACK_ALIGN (see allocate_stack). Therefore, the additional rounding-up step is removed. ALso move the initialization of the default stack size from __pthread_initialize_minimal_internal to __pthread_early_init. This introduces an extra system call during single-threaded startup, but this simplifies the initialization sequence. No locking is needed around the writes to __default_pthread_attr because the process is single-threaded at this point. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Perform signal initialization upon pthread_createFlorian Weimer2021-05-215-88/+131
| | | | | | | | | | | | | Install signal handlers and unblock signals before pthread_create creates the first thread. create_thread in sysdeps/unix/sysv/linux/createthread.c can send SIGCANCEL to the current thread, so the SIGCANCEL handler is currently needed even if pthread_cancel is never called. (The way timer_create uses SIGCANCEL does not need a signal handler; both SIG_DFL and SIG_IGN dispositions should work.) 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).

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