Tue Dec 4 13:19:20 UTC 2018

The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-12-04-1419/flakey.log

The failure seems to be in the "samba" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-12-04-1419/samba.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-12-04-1419/samba.stdout

The top commit at the time of the failure was:

commit 34f4491d79b47b2fe2457b8882f11644cf773bc4
Author: Stefan Metzmacher <metze at samba.org>

    CVE-2018-14629 dns: fix CNAME loop prevention using counter regression

    The loop prevention should only be done for CNAME records!

    Otherwise we truncate the answer records for A, AAAA or
    SRV queries, which is a bad idea if you have more than 20 DCs.
