I've ported all applicable SMB oplock torture tests to SMB2, giving us
a good base for SMB2 oplock testing.
There are several differences between oplocks in SMB and SMB2, mostly
because of differences in W2K3 and W2K8. The existing SMB oplock
tests all pass against W2K3, but several fail against W2K8. These
same tests were failing in SMB2, util I reworked them.
BATCH19, BATCH20: In W2K3/SMB a setfileinfo - rename command wouldn't
cause a sharing violation or break an existing oplock. It appears that
in W2K8/SMB2 a sharing violation is raised.
BATCH22: In W2K3/SMB when a second opener was waiting the full timeout
of an oplock break, it would receive NT_STATUS_SHARING_VIOLATION after
about 35 seconds. This bug has been fixed in W2K8/SMB2 and instead
the second opener succeeds.
LEVELII500: Added 1 new test checking that the server returns a proper
error code when a client improperly replies to a levelII to none break
notification.
STREAM1: W2K8 now grants oplocks on alternate data streams.
