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.

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.
