[libvirt] [PATCH] daemon: Fix regression of libvirtd reloading support

This is introduced by commit df0b57a95a, which forgot to add signal handler for SIGHUP. A simple reproduce method: 1) Create a domain XML under /etc/libvirt/qemu 2) % kill -SIGHUP $(pidof libvirtd) 3) % virsh list --all (the new created domain XML is not listed) --- daemon/libvirtd.c | 13 +++++++++++++ 1 files changed, 13 insertions(+), 0 deletions(-) diff --git a/daemon/libvirtd.c b/daemon/libvirtd.c index b866a01..3e0159b 100644 --- a/daemon/libvirtd.c +++ b/daemon/libvirtd.c @@ -1102,6 +1102,17 @@ static void daemonShutdownHandler(virNetServerPtr srv, virNetServerQuit(srv); } +static void daemonReloadHandler(virNetServerPtr srv ATTRIBUTE_UNUSED, + siginfo_t *sig ATTRIBUTE_UNUSED, + void *opaque ATTRIBUTE_UNUSED) +{ + VIR_INFO(_("Reloading configuration on SIGHUP")); + virHookCall(VIR_HOOK_DRIVER_DAEMON, "-", + VIR_HOOK_DAEMON_OP_RELOAD, SIGHUP, "SIGHUP", NULL); + if (virStateReload() < 0) + VIR_WARN("Error while reloading drivers"); +} + static int daemonSetupSignals(virNetServerPtr srv) { if (virNetServerAddSignalHandler(srv, SIGINT, daemonShutdownHandler, NULL) < 0) @@ -1110,6 +1121,8 @@ static int daemonSetupSignals(virNetServerPtr srv) return -1; if (virNetServerAddSignalHandler(srv, SIGTERM, daemonShutdownHandler, NULL) < 0) return -1; + if (virNetServerAddSignalHandler(srv, SIGHUP, daemonReloadHandler, NULL) < 0) + return -1; return 0; } -- 1.7.6
