[libvirt] [PATCH 04/14] Ensure signal handler propagates fatal signals to default handler

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When replacing the default SEGV/ABORT/BUS signal handlers you can't rely on the process being terminated after your custom handler runs. It is neccessary to manually restore the default handler and then re-raise the signal * src/rpc/virnetserver.c: Restore default handler and raise signal --- src/rpc/virnetserver.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/rpc/virnetserver.c b/src/rpc/virnetserver.c index 5e1719b..d5e9d0a 100644 --- a/src/rpc/virnetserver.c +++ b/src/rpc/virnetserver.c @@ -257,8 +257,9 @@ static void virNetServerFatalSignal(int sig, siginfo_t *siginfo ATTRIBUTE_UNUSED #ifdef SIGUSR2 if (sig != SIGUSR2) { #endif - sig_action.sa_handler = SIG_IGN; + sig_action.sa_handler = SIG_DFL; sigaction(sig, &sig_action, NULL); + raise(sig); #ifdef SIGUSR2 } #endif -- 1.7.6
