From 72c0a2c255b172ebbb2a2b7dab7c9aec4c9582d9 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 15 Jun 2015 20:13:23 +0200 Subject: everywhere: port everything to sigprocmask_many() and friends This ports a lot of manual code over to sigprocmask_many() and friends. Also, we now consistly check for sigprocmask() failures with assert_se(), since the call cannot realistically fail unless there's a programming error. Also encloses a few sd_event_add_signal() calls with (void) when we ignore the return values for it knowingly. --- src/nspawn/nspawn.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'src/nspawn') diff --git a/src/nspawn/nspawn.c b/src/nspawn/nspawn.c index c87956bb01..fed77383c3 100644 --- a/src/nspawn/nspawn.c +++ b/src/nspawn/nspawn.c @@ -4465,7 +4465,7 @@ int main(int argc, char *argv[]) { int r, n_fd_passed, loop_nr = -1; char veth_name[IFNAMSIZ]; bool secondary = false, remove_subvol = false; - sigset_t mask, mask_chld; + sigset_t mask_chld; pid_t pid = 0; int ret = EXIT_SUCCESS; union in_addr_union exposed = {}; @@ -4664,9 +4664,7 @@ int main(int argc, char *argv[]) { log_info("Spawning container %s on %s.\nPress ^] three times within 1s to kill container.", arg_machine, arg_image ?: arg_directory); - assert_se(sigemptyset(&mask) == 0); - sigset_add_many(&mask, SIGCHLD, SIGWINCH, SIGTERM, SIGINT, -1); - assert_se(sigprocmask(SIG_BLOCK, &mask, NULL) == 0); + assert_se(sigprocmask_many(SIG_BLOCK, NULL, SIGCHLD, SIGWINCH, SIGTERM, SIGINT, -1) >= 0); assert_se(sigemptyset(&mask_chld) == 0); assert_se(sigaddset(&mask_chld, SIGCHLD) == 0); -- cgit v1.2.3-54-g00ecf
