smbd: Don't store num_read_oplocks in brlock.tdb 2019-07-04T14:03:29+00:00 Volker Lendecke vl@samba.org 2019-06-30T17:51:13+00:00 8bae5d82e2a101d37f5572e1d174b37816576840 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.

Right now we already need that when accessing leases.tdb, and soon it will be required for brlock.tdb as well. It does not give direct access to the parsed share mode entry, but the record is available for dbwrap_watched_wakeup() within downgrade_lease(). It can be freely nested with get_share_mode_lock calls, the record will be shared and proper nesting should be checked.
