2011-06-20	tdb_traverse/tdb_traverse_read: check returns for negative, not -1.	Rusty Russell	1	-2/+2
	TDB2 returns a negative error number on failure. This is compatible if we always check for < 0 instead of == -1. Also, there's no tdb_traverse_read in TDB2: we don't try to make traverse reliable any more, so there are no write locks anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-09	lib/util Bring procid_str() into lib/util as server_id_string()	Andrew Bartlett	1	-6/+6
	This is needed for OpenChange, which prints Samba struct server_id values in debug messages. Andrew Bartlett

2011-03-02	s3-server_id: only include server_id where needed.	Günther Deschner	1	-0/+1

	This avoids this structure being partially uninitialised. Adnrew Bartlett

2010-03-10	s3: Fix a long-standing problem with recycled PIDs	Volker Lendecke	1	-0/+153
	When a samba server process dies hard, it has no chance to clean up its entries in locking.tdb, brlock.tdb, connections.tdb and sessionid.tdb. For locking.tdb and brlock.tdb Samba is robust by checking every time we read an entry from the database if the corresponding process still exists. If it does not exist anymore, the entry is deleted. This is not 100% failsafe though: On systems with a limited PID space there is a non-zero chance that between the smbd's death and the fresh access, the PID is recycled by another long-running process. This renders all files that had been locked by the killed smbd potentially unusable until the new process also dies. This patch is supposed to fix the problem the following way: Every process ID in every database is augmented by a random 64-bit number that is stored in a serverid.tdb. Whenever we need to check if a process still exists we know its PID and the 64-bit number. We look up the PID in serverid.tdb and compare the 64-bit number. If it's the same, the process still is a valid smbd holding the lock. If it is different, a new smbd has taken over. I believe this is safe against an smbd that has died hard and the PID has been taken over by a non-samba process. This process would not have registered itself with a fresh 64-bit number in serverid.tdb, so the old one still exists in serverid.tdb. We protect against this case by the parent smbd taking care of deregistering PIDs from serverid.tdb and the fact that serverid.tdb is CLEAR_IF_FIRST. CLEAR_IF_FIRST does not work in a cluster, so the automatic cleanup does not work when all smbds are restarted. For this, "net serverid wipe" has to be run before smbd starts up. As a convenience, "net serverid wipedbs" also cleans up sessionid.tdb and connections.tdb. While there, this also cleans up overloading connections.tdb with all the process entries just for messaging_send_all(). Volker
