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.

2010-04-05Add FSCTL_QUERY_ALLOCATED_RANGES to the list of Windows ioctls we support.Jeremy Allison1-0/+52
Based on a patch reported and tested by Ira Cooper <samba@ira.wakeful.net>. Jeremy.
2010-04-05Fix issue with aio where r/w lock wasn't kept across aio read operations.Jeremy Allison2-49/+108
Change schedule_aio_read_and_X/schedule_aio_write_and_X to return NTSTATUS. Move the grant and release of the lock into the aio code. Jeremy
2010-04-01Move initialize_async_io_handler() inside of smbd/aio.c.Jeremy Allison2-37/+42
Call from actual aio read or write. No reason to call this globally on startup. Jeremy.
2010-03-31Make smbd_lock_socket/smbd_unlock_socket recursive with a ref_count.Jeremy Allison6-56/+68
As these always call exit_server, make that part of the function. Use _internal functions for the echo client. Metze please check ! Jeremy.

2010-03-25s3: Make sure our CLEAR_IF_FIRST optimization works for serverid.tdbVolker Lendecke1-0/+4
In the child, we fully re-open serverid.tdb, which leads to one fcntl lock for CLEAR_IF_FIRST detection per smbd. This opens the tdb in the parent and holds it, so that tdb_reopen_all correctly catches the CLEAR_IF_FIRST bit.
2010-03-25s3: Make sure our CLEAR_IF_FIRST optimization works for the notify tdbsVolker Lendecke2-0/+31
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.

2010-03-22s3: Add "log writeable files on exit" parameterVolker Lendecke1-0/+31
This boolean option controls whether at exit time the server dumps a list of files with debug level 0 that were still open for write. This is an administrative aid to find the files that were potentially corrupt if the network connection died.
