However if psmisc is -built on a Linux >= 5.1 system but run on a < 5.1 Linux -system the system call fails and killall doesn't work. - -The fix, as proposed by Peter T. Breuer, is to try -pidfd_send_signal() and if the return value is < 0 and -errno is ENOSYS then we know at runtime the system call -failed and we fall through to trusty old kill(). - -Note, this means that killall on systems below 5.1 still -have the race PID condition that the pidfd calls fix. - -References: - https://bugs.debian.org/1015228 ---- a/src/killall.c -+++ b/src/killall.c -@@ -326,7 +326,12 @@ my_send_signal( - { - #ifdef __NR_pidfd_send_signal - if (pid > 0) /* Not PGID */ -- return syscall(__NR_pidfd_send_signal, pidfd, sig, NULL, 0); -+ { -+ int ret = syscall(__NR_pidfd_send_signal, pidfd, sig, NULL, 0); -+ if (ret >= 0 || errno != ENOSYS) -+ return ret; -+ // fall through if no such syscall -+ } - #endif - return kill(pid, sig); - } -GitLab |
