Fix possible use-after-free on exit #151

Closed debarshiray closed 8 years ago

debarshiray commented 8 years ago

When the last client of dleyna-server exits, and dleyna-server tries to exit, it might use the "upnp" pointer after it was freed as we receive a signal where the user_data is invalid. Avoid that by zero'ing freed pointers and disconnecting from the signal for which "upnp" is user_data.

Yes - I agree this is good fix...
