Hi Steve,
The most important fix is 1/5 that should fix those random hangs that
we've observed while running dfs tests on buildbot.
I have run twice 50 dfs tests against Windows 2022 and samba 4.16 with
these mount options
vers=3.1.1,echo_interval=10,{,hard}
vers=3.0,echo_interval=10,{,hard}
vers=3.0,echo_interval=10,{,sign}
vers=3.0,echo_interval=10,{,seal}
vers=2.1,echo_interval=10,{,hard}
vers=1.0,echo_interval=10,{,hard}
The only tests which failed (2%) were with SMB1 UNIX extensions
against samba. readdir(2) was getting STATUS_INVALID_LEVEL from
QUERY_PATH_INFO after failover for some reason -- I'll look into that
when time allows. Those failures aren't related to this series,
though.
I also did some quick tests with kerberos.
