s3:locking: add brl_req_guid() and brl_req_mem_ctx() helper functions

2019-09-09T14:23:41+00:00

This allows the vfs backend to detect a retry and keep state between
the retries.

s3:brlock: always return LOCK_NOT_GRANTED instead of FILE_LOCK_CONFLICT

2019-09-09T14:23:40+00:00

Returning NT_STATUS_FILE_LOCK_CONFLICT is a SMB1 only detail
for delayed brlock requests, which is handled in
smbd_smb1_do_locks*().

The brlock layer should be consistent even for posix locks.

smbd: Don't store num_read_oplocks in brlock.tdb

2019-07-04T14:03:29+00:00

This removes a kludgy implementation that worked around a locking
hierarchy problem: Setting a byte range lock had to contend the level2
oplocks, which are stored in locking.tdb/leases.tdb. We could not
access locking.tdb in the brlock.tdb code, as brlock.tdb might have
been locked first without locking.tdb, violating the locking hierarchy
locking.tdb->brlock.tdb. Now that that problem is gone (see the commit
wrapping do_lock() in share_mode_do_locked()), we can remove this
kludge.
