2013-10-17s3:include: fix messaging_send_buf() protype in messages.hStefan Metzmacher1-1/+1

2012-04-17s3: Add messaging_tdb_event()Volker Lendecke1-0/+3
This is a void* that represents a signal handler attached to some custom tevent_context. This is necessary to make the tdb based messaging infrastructure trigger its business when we are sitting in tevent_loop_once for an event context that is not the main one in the messaging context.

2011-08-11s3-messaging: Change classification of MSG_SMB_CONF_UPDATED.Simo Sorce1-1/+0
smbd is not the only daemon interested in smb.conf changes. Move this message to the GENERAL class so that all interested partied (nmbd, winbindd, spoolssd, etc..) can receive this notification. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-11s3-messaging: Fix messaging classes.Simo Sorce1-1/+1
This has been broken since ff0ac5b0 (May 2007). Basically all messages were belonging to the General class except for CTDB messages. This fixed the message_send_all() function to correctly compute the class, and fixes registrations to include all they need to cope with the fact not all messages are of calss general (registrations rotted a bit because as long as FLAG_MSG_GENERAL was defined the process woould receive all messages).

2010-03-25s3: Make sure our CLEAR_IF_FIRST optimization works for messaging.tdbVolker Lendecke1-0/+2
In the child, we fully re-open messaging.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.
2010-03-10s3: Fix a long-standing problem with recycled PIDsVolker Lendecke1-0/+1
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

2007-10-10r23410: Merge the core of the cluster code.Volker Lendecke1-0/+36
I'm 100% certain I've forgotten to merge something, but the main code should be in. It's mainly in dbwrap_ctdb.c, ctdbd_conn.c and messages_ctdbd.c. There should be no changes to the non-cluster case, it does survive make test on my laptop. It survives some very basic tests with ctdbd enables, I did not do the full test suite for clusters yet.

Secondly, this patch does not call the checker routines in smbcontrol directly but depends on a running smbd. (This used to be commit 7e39d77c1f90d9025cab08918385d140e20ca25b)

This way we could theoretically add the MSG_FLAG_NODUPLICATES again, but I would rather not do this, because that one is racy and can't be guaranteed at all.

doing this because for the clustering the marshalling is needed in more than one place, so I wanted a decent routine to marshall a message_rec struct which was not there before. Tridge, this seems about the same speed as it used to be before, the librpc/ndr overhead in my tests was under the noise. Volker (This used to be commit eaefd00563173dfabb7716c5695ac0a2f7139bb6)

2007-10-10r14898: This change is an attempt to improve the quality of the information thatJames Peach1-0/+1
is produced when a process exits abnormally. First, we coalesce the core dumping code so that we greatly improve our odds of being able to produce a core file, even in the case of a memory fault. I've removed duplicates of dump_core() and split it in two to reduce the amount of work needed to actually do the dump. Second, we refactor the exit_server code path to always log an explanation and a stack trace. My goal is to always produce enough log information for us to be able to explain any server exit, though there is a risk that this could produce too much log information on a flaky network. Finally, smbcontrol has gained a smbd fault injection operation to test the changes above. This is only enabled for developer builds. (This used to be commit 56bc02d64498eb3faf89f0c5452b9299daea8e95)
