Adhemerval Zanella	7dd416491e	linux: Fix __sem_check_add_mapping search_sem Similar to __sem_check_add_mapping fix, take in consideration the trailling NULL. Checked x86_64-linux-gnu.	2021-02-09 16:09:51 -03:00
Adhemerval Zanella	e99156816d	linux: Fix __sem_check_add_mapping name length Take in consideration the trailling NULL since sem_search uses strcmp to compare entries. Checked on x86_64-linux-gnu and powerpc-linux-gnu (where it triggered a nptl/tst-sem7 regression).	2021-02-09 14:42:55 -03:00
Adhemerval Zanella	c1f46f9db7	pthread: Remove alloca usage from __sem_check_add_mapping sem_open already returns EINVAL for input names larger than NAME_MAX, so it can assume the largest name length with tfind. Checked on x86_64-linux-gnu.	2021-02-08 14:10:42 -03:00
Adhemerval Zanella	da4aea0b5e	pthread: Refactor semaphore code 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.	2021-02-08 14:10:42 -03:00
