reg_perfcount currently uses a counters_directory() helper to return the
counter specific tdb path. Fix leaks and error checking in the helper
function and all callers.

When a createkey fails due to access denied, we need to do a

This is in preparation to support handing flags to backends,
in particular activating read only record support for ctdb
databases. For a start, this does nothing but adding the
parameter, and all databases use DBWRAP_FLAG_NONE.

This prevents race between fetching seqnum and key content.
Because there is currently no way to atomically fetch the
record along with the seqnum, I use a loop.
This is far from optimal and should should ideally be done
differently. But for now it fixes the race.

The purpose is to prevent next reads from going to disk.
Note that this will currently only be effective with local tdbs, not
with ctdb: For tdb, store and delete bump the seqnum while transaction
commit does not. For ctdb, transaction commit bumps the seqnum, while
store and delete don't... This needs fixing (in ctdb).

Note that this will currently only be effective in the local TDB implementation.
For CTDB, this wont work since seqnum currently works differently there (needs
fixing): For tdb, store and delete operations bump the db seqnum, while
transaction commits don't. For ctdb, the seqnum is bumped by the transaction
commit but not by store and delete operations.

This is wrong layering (calling into regdb_transaction* in the reg_api code)
but fixes a potential race. It makes the multi-step create procedure atomic.
This should completely be done in the backend.

This is at the wrong layer, but if fixes a race potentially causing
data corruption by concurrent access.
Signed-off-by: Andreas Schneider <asn@samba.org>
(there was no lock around fetching the values and storing them)
The layering is wrong in that it uses regdb transactions in reg_api

This will be used to enforce a lock hierarchy between the databases. We have
seen deadlocks between locking.tdb, brlock.tdb, serverid.tdb and notify*.tdb.
These should be fixed by refusing a dbwrap_fetch_locked that does not follow a
defined lock hierarchy.
As reported by Ismail Doenmez (idonmez@suse.com), sizeof() is
incorrectly used by _reg_perfcount_init_data_block() in an attempt to
determine the length of a talloced array.
