2010-03-10s3: Fix a long-standing problem with recycled PIDsVolker Lendecke1-0/+4
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
2010-02-12s3: Implement global locks in a g_lock tdbVolker Lendecke1-0/+3
This is the basis to implement global locks in ctdb without depending on a shared file system. The initial goal is to make ctdb persistent transactions deterministic without too many timeouts.
2009-11-08Revert "s3: Make run_rpc_command take strings instead of a ndr_interface_table"Volker Lendecke1-2/+1
This reverts commit 53f2a1595e76db9fe1b42db65b51895b73365993.

2009-09-29s3: Remove the lua interpreter againVolker Lendecke1-4/+0
This was meant to support async winbind. But as the hairy parts of async winbind (getgrent) are done without it, it can go again.
2009-07-22Revert "net: Use samba default command line arguments."Kai Blin1-0/+3
This reverts commit fb262f79fab00374023e59476e8d05a1015a7041 and related commits c36031778e1983ddb11d3e1fcab35e738dbf94bc 72fd5fa6bb78a054fad5e5ebe19a0c0387a7d45b and 38cd0e086f50ce54d88a19aa5a6803469af90489 This change caused more trouble than it solved. We need to do this differently. Reverting so we don't accidently release this.
2009-05-25net: Use samba default command line arguments.Kai Blin1-3/+0
Attention: The meaning of the -N flag changed. To get the old meaning for net groupmap set, use the long option --ntname The long option for using kerberos changed from --kerberos to --use-kerberos net rpc commands will now prompt for a password if none is given. As a benefit, net will now accept an authentication file like other samba command line tools. So no need to specify the password on the command line in scripts anymore. This should fix bug #6357 Signed-off-by: Kai Blin <kai@samba.org>

2008-12-17net luaVolker Lendecke1-0/+5
This adds a lua command line interpreter with some sample code how to build your own data types based on our internal data types. Not meant as the final word, but as a playground for experiments for people. Might be removed later when we find this turns out to be too awkward.
