------------------------------------
Summary: C epoll proactor listener cleanup race
Key: PROTON-1531
URL: https://issues.apache.org/jira/browse/PROTON-1531
Project: Qpid Proton
Issue Type: Bug
Components: proton-c
Affects Versions: proton-c-0.18.0
Reporter: Cliff Jansen
Assignee: Cliff Jansen
Fix For: proton-c-0.18.0
It is possible that closing a listener while an incoming connection is about to
trigger an epoll event on the listener can result in accessing free'd memory.
The solution is to force an event event to fire via a shutdown() call on the
socket and delay deletion until the callback completes. This strategy is
already in use by the pconnection cleanup logic, which can be used as a
template.
