+Subject: [PATCH] Avoid infinite-loop in avahi-daemon by handling HUP event in
+ client_work
+
+If a client fills the input buffer, client_work() disables the
+AVAHI_WATCH_IN event, thus preventing the function from executing the
+`read` syscall the next times it is called. 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

+Subject: [PATCH] Fix NULL pointer crashes from #175
+
+avahi-daemon is crashing when running "ping .local".
+The crash is due to failing assertion from NULL pointer.
+Add missing NULL pointer checks to fix it.
+
+Introduced in #175 - merge commit 8f75a045709a780c8cf92a6a21e9d35b593bdecd
