Denys Vlasenko	91e11eba6e	ash: jobs: Fix waitcmd busy loop Upstream commit: Date: Tue, 2 Jun 2020 23:46:48 +1000 jobs: Fix waitcmd busy loop We need to clear gotsigchld in waitproc because it is used as a loop conditional for the waitcmd case. Without it waitcmd may busy loop after a SIGCHLD. This patch also changes gotsigchld into a volatile sig_atomic_t to prevent compilers from optimising its accesses away. Fixes: 6c691b3e5099 ("jobs: Only clear gotsigchld when waiting...")

Denys Vlasenko	8d5f465a20	ash: jobs: Fix infinite loop in waitproc Upstream commit: Date: Fri, 10 Apr 2020 21:03:09 +1000 jobs: Fix infinite loop in waitproc After we changed the resetting of gotsigchld so that it is only done if jp is NULL, we can now get an infinite loop in waitproc if gotsigchld is set but there is no outstanding child because everything had been waited for previously without gotsigchld being zeroed. This patch fixes it by always zeroing gotsigchld as we did before. The bug that the previous patch was trying to fix is now resolved by switching the blocking mode to DOWAIT_NORMAL after the specified job has been completed so that we really do wait for all outstanding dead children.
