However, if the client then -terminates the connection, the socket file descriptor receives a HUP -event, which is not handled, thus the kernel keeps marking the HUP event -as occurring. While iterating over the file descriptors that triggered -an event, the client file descriptor will keep having the HUP event and -the client_work() function is always called with AVAHI_WATCH_HUP but -without nothing being done, thus entering an infinite loop. - -See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=984938 ---- - avahi-daemon/simple-protocol.c | 5 +++++ - 1 file changed, 5 insertions(+) - -diff --git a/avahi-daemon/simple-protocol.c b/avahi-daemon/simple-protocol.c -index 3e0ebb11..6c0274d6 100644 ---- a/avahi-daemon/simple-protocol.c -+++ b/avahi-daemon/simple-protocol.c -@@ -424,6 +424,11 @@ static void client_work(AvahiWatch *watch, AVAHI_GCC_UNUSED int fd, AvahiWatchEv - } - } - -+ if (events & AVAHI_WATCH_HUP) { -+ client_free(c); -+ return; -+ } -+ - c->server->poll_api->watch_update( - watch, - (c->outbuf_length > 0 ?
