From ce30c8dcb41dfe9264f79f30c7f51c0e74576638 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sun, 31 May 2015 23:55:55 +0200 Subject: tree-wide: whenever we fork off a foreign child process reset signal mask/handlers Also, when the child is potentially long-running make sure to set a death signal. Also, ignore the result of the reset operations explicitly by casting them to (void). --- src/login/inhibit.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/login') diff --git a/src/login/inhibit.c b/src/login/inhibit.c index 57cfb5d0b5..0e5dce5925 100644 --- a/src/login/inhibit.c +++ b/src/login/inhibit.c @@ -33,6 +33,7 @@ #include "strv.h" #include "formats-util.h" #include "process-util.h" +#include "signal-util.h" static const char* arg_what = "idle:sleep:shutdown"; static const char* arg_who = NULL; @@ -274,6 +275,9 @@ int main(int argc, char *argv[]) { if (pid == 0) { /* Child */ + (void) reset_all_signal_handlers(); + (void) reset_signal_mask(); + close_all_fds(NULL, 0); execvp(argv[optind], argv + optind); -- cgit v1.2.3-54-g00ecf
