+Subject: BUG/MAJOR: dns: Broken kqueue events handling (BSD systems).
+X-Git-Url: http://git.haproxy.org/?p=haproxy.git;a=commitdiff_plain;h=64920538fc19f3c7f94dfa1e84a9a6569b8c3d37

+BUG/MAJOR: dns: Broken kqueue events handling (BSD systems).
+
+Some DNS related network sockets were closed without unregistering their file
+descriptors from their underlying kqueue event sets. This patch replaces calls to
+close() by fd_delete() calls to that to delete such events attached to DNS
+network sockets from the kqueue before closing the sockets.
+
+The bug was introduced by commit 26c6eb8 ("BUG/MAJOR: dns: restart sockets
+after fork()") which was backported in 1.7 so this fix has to be backported
+there as well.
+
+Thanks to Jim Pingle who reported it and indicated the faulty commit, and
+to Lukas Tribus for the trace showing the bad file descriptor.
