* htl: Move thread table to ld.soSergey Bugaev2021-09-161-2/+0
| | | | | | | | | | | The next commit is going to introduce a new implementation of THREAD_GSCOPE_WAIT which needs to access the list of threads. Since it must be usable from the dynamic laoder, we have to move the symbols for the list of threads into the loader.

* htl: Let libc call __pthread_mutex_{,try,un}lockSamuel Thibault2021-07-131-0/+1
| | | | | Now that NPTL was moved to libc, libc makes internal __pthread calls, so htl has to expose them internally.
* linux: Require /dev/shm as the shared memory file systemFlorian Weimer2021-02-081-1/+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.
* htl: Add missing symbolsSamuel Thibault2020-12-031-0/+2
| | | | | hurd/hurdsig.c needs to detect whether __pthread_detach and __pthread_create are available, so they need to be exposed.
* htl: Initialize laterSamuel Thibault2020-11-111-2/+2
| | | | | | | | Since htl does not actually need a stack switch, we can initialize it like nptl is, avoiding all sorts of startup issues with ifunc. More precisely, htl defines __pthread_initialize_minimal instead of the elder _cthread_init_routine. We can then drop the stack switching dances.
* htl: Move cleanup stack to variable shared between libc and pthreadSamuel Thibault2020-06-141-0/+1
| | | | | | | | | | | | | | | | | | | | If libpthread gets loaded dynamically, the stack needs to already contain the cleanup handlers of the main thread. * htl/libc_pthread_init.c (__pthread_cleanup_stack): New per-thread variable. * htl/Versions (libc): Add __pthread_cleanup_stack as private symbol. * htl/pt-internal.h (struct __pthread): Remove cancelation_handlers field. (__pthread_cleanup_stack): Add variable declaration. * htl/pt-alloc.c (initialize_pthread): Remove initialization of cancelation_handlers field. * htl/pt-cleanup.c (__pthread_get_cleanup_stack): Return the address of __pthread_cleanup_stack instead of that of the cancelation_handlers field. * htl/forward.c: Include <pt-internal.h>. (dummy_list): Remove variable. (__pthread_get_cleanup_stack): Return the address of __pthread_cleanup_stack instead of that of dummy_list.
