2023-08-08htl: Initialize ___pthread_self earlySamuel Thibault2-17/+1
When using jemalloc, malloc() needs to use TSD, while libpthread initialization needs malloc(). Having ___pthread_self set early to some static storage allows TSD to work early, thus allowing jemalloc and libpthread to initialize together. This incidentaly simplifies __pthread_enable/disable_asynccancel and __pthread_self, now that ___pthread_self is always initialized.

2023-02-12mach, hurd: Cast through uintptr_tSergey Bugaev1-2/+3
When casting between a pointer and an integer of a different size, GCC emits a warning (which is escalated to a build failure by -Werror). Indeed, if what you start with is a pointer, which you then cast to a shorter integer and then back again, you're going to cut off some bits of the pointer. But if you start with an integer (such as mach_port_t), then cast it to a longer pointer (void *), and then back to a shorter integer, you are fine. To keep GCC happy, cast through an intermediary uintptr_t, which is always the same size as a pointer.

2022-08-02htl: Let pthread_self and cancellability called earlySamuel Thibault2-1/+15
When applications redirect some functions they might get called before libpthread is fully initialized. They may still expected pthread_self and cancellable functions to work, so cope with such calls in that situation.
2022-02-14htl: Destroy thread-specific data before releasing joinsSamuel Thibault1-3/+3
Applications may want to assume that after pthread_join() returns, all thread-specific data has been released.
2022-01-22htl: Fix cleaning the reply portSamuel Thibault6-25/+27
If any RPC fails, the reply port will already be deallocated. __pthread_thread_terminate thus has to defer taking its name until the very last __thread_terminate_release which doesn't reply a message. But then we have to read from the pthread structure. This introduces __pthread_dealloc_finish() which does the recording of the thread termination, so the slot can be reused really only just before the __thread_terminate_release call. Only the real thread can set it, so let's decouple this from the pthread_state by just removing the PTHREAD_TERMINATED state and add a terminated field.

I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah.

d482ebfa6785 ('htl: Keep thread signals blocked during its initialization') fixed not letting signals get delivered too early during thread creation, but it also affected the main thread, thus making it block signals by default. We need to just let the main thread sigset as it is.

The next commit is going to introduce a new implementation of THREAD_GSCOPE_WAIT which needs to access the list of threads.

2021-09-03Remove "Contributed by" linesSiddhesh Poyarekar1-1/+0
We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2021-07-13htl: Let libc call __pthread_mutex_{,try,un}lockSamuel Thibault1-0/+1
Now that NPTL was moved to libc, libc makes internal __pthread calls, so htl has to expose them internally.
2021-06-24Consolidate pthread_atforkAdhemerval Zanella1-3/+1
The pthread_atfork is similar between Linux and Hurd, only the compat version bits differs. The generic version is place at sysdeps/pthread with a common name. It also fixes an issue with Hurd license, where the static-only object did not use LGPL + exception. Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for i686-gnu.
2021-06-03dlfcn: Cleanups after -ldl is no longer requiredFlorian Weimer1-1/+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.

2021-03-29fork.h: replace with register-atfork.hSamuel Thibault1-1/+0
UNREGISTER_ATFORK is now defined for all ports in register-atfork.h, so most previous includes of fork.h actually only need register-atfork.h now, and cxa_finalize.c does not need an ifdef UNREGISTER_ATFORK any more. The nptl-specific fork generation counters can then go to pthreadP.h, and fork.h be removed. Checked on x86_64-linux-gnu and i686-gnu. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2021-03-12posix: Consolidate register-atforkAdhemerval Zanella2-158/+1
Both htl and nptl uses a different data structure to implement atfork handlers. The nptl one was refactored by 27761a1042d to use a dynarray which simplifies the code. This patch moves the nptl one to be the generic implementation and replace Hurd linked one. Different than previous NPTL, Hurd also uses a global lock, so performance should be similar. Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for i686-gnu.
2021-02-08pthread: Refactor semaphore codeAdhemerval Zanella2-21/+1
The internal semaphore list code is moved to a specific file, sem_routine.c, and the internal usage is simplified to only two functions (one to insert a new semaphore and one to remove it from the internal list). There is no need to expose the internal locking, neither how the semaphore mapping is implemented. No functional or semantic change is expected, tested on x86_64-linux-gnu.
2021-02-08linux: Require /dev/shm as the shared memory file systemFlorian Weimer2-3/+0
Previously, glibc would pick an arbitrary tmpfs file system from /proc/mounts if /dev/shm was not available. This could lead to an unsuitable file system being picked for the backing storage for shm_open, sem_open, and related functions. This patch introduces a new function, __shm_get_name, which builds the file name under the appropriate (now hard-coded) directory. It is called from the various shm_* and sem_* function. Unlike the SHM_GET_NAME macro it replaces, the callers handle the return values and errno updates. shm-directory.c is moved directly into the posix subdirectory because it can be implemented directly using POSIX functionality. It resides in libc because it is needed by both librt and nptl/htl. In the sem_open implementation, tmpfname is initialized directly from a string constant. This happens to remove one alloca call. Checked on x86_64-linux-gnu.
