If a new process is started with -sf and it fails to bind, it may send a SIGTTOU to the master process in hope that it will temporarily unbind. Unfortunately this one doesn't catch it and stops to background instead of forwarding the signal to the workers. The same is true for SIGTTIN. This commit simply implements an extra signal handler for the master to deal with such signals that must be passed down to the workers. It must be backported as far as 1.8, though there the code differs in that it's entirely in haproxy.c and doesn't require an extra sig handler. |
