From b0d1ca9ebf605abb63b95ef73d56d56a1109002e Mon Sep 17 00:00:00 2001 From: Ray Strode Date: Wed, 18 Jul 2018 16:40:58 -0400 Subject: session-worker: unblock SIGUSR1 before PAM Right now we unblock SIGUSR1 just before starting the session, but we should really do it before starting the worker/PAM. This commit fixes that and removes a useless call to set SIGUSR1 back to the default disposition, right before exec (which does the same thing anyway) Closes: https://gitlab.gnome.org/GNOME/gdm/issues/399 --- daemon/gdm-session-worker-job.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'daemon/gdm-session-worker-job.c') diff --git a/daemon/gdm-session-worker-job.c b/daemon/gdm-session-worker-job.c index 69dca2e5..7f3b4c14 100644 --- a/daemon/gdm-session-worker-job.c +++ b/daemon/gdm-session-worker-job.c @@ -117,12 +117,19 @@ session_worker_job_setup_journal_fds (void) static void session_worker_job_child_setup (GdmSessionWorkerJob *session_worker_job) { + sigset_t mask; session_worker_job_setup_journal_fds (); /* Terminate the process when the parent dies */ #ifdef HAVE_SYS_PRCTL_H prctl (PR_SET_PDEATHSIG, SIGTERM); #endif + /* + * Reset signal mask to default since it was altered by the + * manager process + */ + sigemptyset (&mask); + sigprocmask (SIG_SETMASK, &mask, NULL); } static void -- cgit v1.2.1
