If a client connects to a non-public address first followed by a connect to public address with the same client_guid and a connection to the non-public address gets disconnected first, we hit by a use-after-free talloc_get_type_abort() called from release_ip() as "xconn" is already gone, taking smbd_release_ip_state with it. We need to decide between calling ctdbd_unregister_ips() by default, as it means the tcp connection is really gone and ctdb needs to remove the 'tickle' information. But when a connection was passed to a different smbd process, we need to use ctdbd_passed_ips() as the tcp connection is still alive and the 'tickle' information should not be removed within ctdb.

# Files in this directory contain lists of regular expressions # matching the names of tests that are that are flapping. In other # words, they sometimes succeed and sometimes fail, depending on # external factors. # # "make test" will not report failures or successes for tests listed here. # # DO NOT ADD TESTS HERE UNLESS THEY ARE ACTUALLY FLAPPING # # It is much better to add known failing tests to 'knownfail', so the # test system can warn when they actually start passing. # # Empty lines and lines beginning with '#' are ignored. # Please don't add tests to this README!
