Sun Mar 31 10:59:50 UTC 2019

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:

The failure seems to be in the "samba-nt4" suite, whose build logs are available here:

    libcli: permit larger values of DataLength in SMB2_ENCRYPTION_CAPABILITIES of negotiate response

    Certain Netapp versions are sending SMB2_ENCRYPTION_CAPABILITIES
    structures containing DataLength field that includes the padding
    [0]. Microsoft has since clarified that only values smaller than
    the size are considered invalid [1].

    While parsing the NegotiateContext it is ensured that DataLength
    does not exceed the message bounds. Also, the value is not
    actually used anywhere outside the validation. Thus values
    greater than the actual data size are safe to use. This patch
    makes Samba fail only on values that are too small for the (fixed
    size) payload.
