Adam Yi 436a604b7d posix: Fix system blocks SIGCHLD erroneously [BZ #30163] ... Fix bug that SIGCHLD is erroneously blocked forever in the following scenario: 1. Thread A calls system but hasn't returned yet 2. Thread B calls another system but returns SIGCHLD would be blocked forever in thread B after its system() returns, even after the system() in thread A returns. Although POSIX does not require, glibc system implementation aims to be thread and cancellation safe. This bug was introduced in 5fb7fc9635 when we moved reverting signal mask to happen when the last concurrently running system returns, despite that signal mask is per thread. This commit reverts this logic and adds a test. Signed-off-by: Adam Yi <ayi@janestreet.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>		2023-03-07 09:54:50 -03:00
