Description Steven Danneman 2009-12-02 19:21:36 UTC
The MS-CIFS spec, section 2.2.4.32.1 states that only a single lock cancel
request can be made per PDU.  The Samba4 server handles this correctly, but
then returns an incorrect error code when a locked file is unlocked.

Interestingly, Windows servers do not conform to the spec and allow multiple
lock cancellation requests to be made without error.

This behavior is exercised by the RAW-LOCK-ASYNC smbtorture4 test.

samba4.raw.lock.*.async should be removed from 
source4/selftest/knownfail when this bug is fixed.
Comment 2 Matthias Dieter Wallnöfer 2010-03-08 04:33:23 UTC
Reassign file server related bugs up to tridge.
