2010-03-22s3: Fix a bad memleak in winbindVolker Lendecke1-1/+2
2010-03-10s3: Fix a long-standing problem with recycled PIDsVolker Lendecke1-1/+6
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
2010-03-05s3:winbindd: add DEBUG(10,...) for the end of each top levelStefan Metzmacher1-6/+24
That will hopefully make debugging a bit easier (at least for me). metze

2009-12-26s3: winbindd_cli_state->getgrent_state is no longer usedVolker Lendecke1-4/+0
2009-12-26s3: getgrent_state has been replaced by grent_stateVolker Lendecke1-1/+1
2009-12-21s3:winbind: Add a lower-cost alternative to wbinfo -t: wbinfo --ping-dcVolker Lendecke1-0/+2
This just does a NULL RPC call through an existing NETLOGON connection. If someone knows an operation that "just works" and does not return NOT_SUPPORTED, please tell me :-)

2009-07-31Slightly restructure the async winbind request calling conventionVolker Lendecke1-7/+12
The main loop now allocates the response, this has to be done everywhere
2009-07-27Fix a valgrind error in winbindVolker Lendecke1-1/+2
When looking for idle clients, we dereferenced state->response. As this is dynamically allocated now, the proper test is whether state->response exists at all. This is the case when an async operation is in process at that moment.
2009-07-25Fix a winbind memleakVolker Lendecke1-0/+1
2009-07-15Make gencache more stableVolker Lendecke1-0/+2
This provides a compromise between stability and performance: gencache is a persistent database these days that for performance reasons can not use tdb transactions for all writes. This patch splits up gencache into gencache.tdb and gencache_notrans.tdb. gencache_notrans is used with CLEAR_IF_FIRST, writes to it don't use transactions. By default every 5 minutes and when a program exits, all entries from _notrans.tdb are transferred to gencache.tdb in one transaction.

2009-06-14Remove "winbindd_request" and "winbindd_response" from winbindd_cli_stateVolker Lendecke1-6/+10
This shrinks the memory footprint of an idle client by 5592 bytes to 60 bytes on my 32-bit box.
