autobuild[sn-devel-144]: intermittent test failure detected

Tue Jul 31 17:47:53 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-144/2018-07-31-1947/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-144/2018-07-31-1947/samba.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-07-31-1947/samba.stdout

The top commit at the time of the failure was:

commit 8dac16e82d04a64d8dee42285fe3fd32cc26f0af

    smb2_query_directory: make 'return true' explicit in smb2_query_directory_next_entry()

    'return req' should do the same as 'return true' for a bool function,
    it's implicitly expanded as 'return (req!=NULL)?true:false.

    There's no point in that as 'req' is always a valid pointer.

    This was most likely just a copy and paste bug.

    So we make this explicit now and avoid that Coverity reports this:

    CID 1438158:  Null pointer dereferences  (REVERSE_INULL)
    Null-checking "req" suggests that it may be null, but it has already
    been dereferenced on all paths leading to the check.
