The samba4.smb2.lock.CANCEL test is currently failing against Samba4 SMB2 server.
I don't have much more detail at the moment, but the test is exercising the
server's ability to pend a BRL requests, send back and asynchronous response, and
then have that response be canceled with an explicit SMB2_CANCEL request.
This test has been added to source4/selftest/knownfail until the server issue
can be investigated and fixed.
I've modified the test code to reflect the error codes that s4 gives. I
believe that s4 is in fact giving the correct error codes for these tests,
and I've added comments to the torture/smb2/lock.c code explaining my
Thanks very much for the bug report Steven.
