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.
|
||||
|
||||
