+Subject: [PATCH] lib: fix memory leak on connect() failure
+
+Change sockunion_log() to not use strdup(). This fixes a small memory
+leak that occurs on every failed connect(), and is simpler/cleaner.

+Subject: [PATCH] lib: call filter delete hook before freeing access list
+
+The delete_hook was being run after calling access list delete function.
+This would cause ospf to dereference a NULL, in ospf_filter_update
+because 'access->name' was already freed.
