2012-01-18s3: Add a "lock_order" argument to db_openVolker Lendecke1-2/+4
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.
2011-10-13lib/util: Add back control of mmap and hash size in tdb for top level buildAndrew Bartlett1-2/+11
This passes down a struct loadparm_context to allow these parameters to be checked. This may be s3 or s4 context, allowing the #if _SAMBA_BUILD_ macro to go away safely. Andrew Bartlett
2011-10-11s3:smbd: convert notify db to use dbwrap wrapper functionsMichael Adam1-28/+30
Avoid direct use of the db_record and db_context structs.
2011-07-29s3:dbwrap: move all .c and .h files of dbwrap to lib/dbwrap/Michael Adam1-1/+1

2011-07-29s3:dbwrap: move db_open() to a file dbwrap_open.c of its own.Michael Adam1-0/+1
Also start new folder lib/dbwrap/ where dbwrap_open.c is stored and make the fallbacke implementation functoins non-static and create a dbwrap_private.h header file that contains their prototypes.
2011-06-20tdb_compat: Higher level API fixes.Rusty Russell1-1/+1
My previous patches fixed up all direct TDB callers, but there are a few utility functions and the db_context functions which are still using the old -1 / 0 return codes. It's clearer to fix up all the callers of these too, so everywhere is consistent: non-zero means an error. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-09s3-talloc Change TALLOC_ZERO_P() to talloc_zero()Andrew Bartlett1-2/+2
Using the standard macro makes it easier to move code into common, as TALLOC_ZERO_P isn't standard talloc.

2011-05-06lib/util Move source3 tdb_wrap_open() into the common code.Andrew Bartlett1-0/+1
This #if _SAMBA_BUILD == 3 is very unfortunate, as it means that in the top level build, these options are not available for these databases. However, having two different tdb_wrap lists is a worse fate, so this will do for now. Andrew Bartlett

2010-09-27Change to using TDB_INCOMPATIBLE_HASH (the jenkins hash) on allJeremy Allison1-4/+4
TDB_CLEAR_IF_FIRST tdb's. For tdb's like gencache where we open without CLEAR_IF_FIRST and then with CLEAR_IF_FIRST if corrupt this is still safe to use as if opening an existing tdb the new hash will be ignored - it's only used on creating a new tdb not opening an old one. Jeremy.
2010-09-26s3: Remove talloc_autofree_context() from notify_internal_parent_init()Volker Lendecke1-4/+3

2010-04-06fix a segfault in the notify subsystemChristian Ambach1-5/+16
When the notify_array cannot be loaded correctly, do not keep the half-baked parsing results in the global variable. This can lead to segfaults next time notify_load is entered and the seqnum has not changed. This has been seen in a case where mixed smbd versions were running in a CTDB cluster (versions with and w/o commit c216d1e6 that changed the notify_entry structure). There will be missed notifications until all smbds are at the same software level, but this should be acceptable and is better than crashing and interrupting client operations. This fix cleans up the notify_array, removes the unparseable data from the TDB and returns a fresh notify_array that can be worked with. The NDR_PRINT_DEBUG had to be moved to only be called when the parsing succeeded, it was seen to cause additional segfaults. The status variable is intentionally left to NT_STATUS_OK to not make callers abort and report errors to the clients and make them disconnect.

2010-03-25s3: Add a comment to notify_internal_parent_init, this is pretty confusingVolker Lendecke1-0/+6
2010-03-25s3: Make sure our CLEAR_IF_FIRST optimization works for the notify tdbsVolker Lendecke1-0/+27
The notify tdb files are opened at tconX time, which leads to one fcntl lock for CLEAR_IF_FIRST detection per smbd. This opens the tdbs in the parent and holds it, so that tdb_reopen_all correctly catches the CLEAR_IF_FIRST bit.

2009-11-05s3: Fix the talloc hierarchy in notify_remove_onelevelVolker Lendecke1-1/+1
We want to free the record early, not when talloc_tos() is free'ed.
2009-04-30Fix notify_onelevel: notify is not necessarily enabledVolker Lendecke1-0/+4
Thanks to Günther Deschner! Volker
2009-04-16Add notify_onelevel.tdbVolker Lendecke1-0/+286
This optimizes non-recursive notifys. For non-recursive notifies we can use a per-directory file-id indexed notify record. This matters for the Windows Explorer and IIS cases which do not use recursive notifies. In these cases, we do not have to shuffle around the whole notify record on every change. For the cluster case, this improves correctness of the notifies, ctdb only distributes the tdb seqnum once a second, so we can lose notifies.
