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

2010-02-10More of the fix for bug #7118 - nmbd problems with socket address.Jeremy Allison1-0/+89
Add a simple "processed packet queue" cache to stop nmbd responding to packets received on the broadcast and non-broadcast socket (which it has opened when "nmbd bind explicit broadcast = yes"). This is a very simple packet queue - it only keeps the packets processed during a single call to listen_for_packets() (i.e. one select call). This means that if the delivery notification for a packet received on both broadcast and non-broadcast addresses is done in two different select calls, the packet will still be processed twice. This is a very rare occurrance and we can just live with it when it does as the protocol is stateless. If this is ever flagged as a repeatable problem then we can add a longer lived cache, using timeout processing to clear etc. etc. But without storing all packets processed we can never be *sure* we've eliminated the race condition so I'm going to go with this simple solution until someone proves a more complex one is needed :-). Jeremy.

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.

2009-05-27s3: Allow child processes to exit gracefully if we are out of fdsMarc VanHeyningen2-4/+4
When we run out of file descriptors for some reason, every new connection forks a child that immediately panics causing smbd to coredump. This seems unnecessarily harsh; with this code change we now catch that error and merely log a message about it and exit without the core dump. Signed-off-by: Tim Prouty <tprouty@samba.org>

2009-02-04Have nmbd check all available interfaces for WINS before failingAravind Srinivasan2-2/+4
When nmbd is acting as WINS, it picks the first interface's IP as WINS server's IP. If the first interface's IP is zero, we will just quit (even though we might have other interfaces with valid IPs). This patch makes nmbd look at all interfaces and pick the first interface with a valid IP as the WINS server's IP.

2009-01-15s3: make better use of ccache by not including version.h in every C-file.Michael Adam1-1/+1
version.h changes rather frequently. Since it is included via includes.h, this means each C file will be a cache miss. This applies to the following situations: * When building a new package with a new Samba version * building in a git branch after calling mkversion.sh after a new commit (i.e. virtually always) This patch improves the situation in the following way: * remove inlude "version.h" from includes.h * Use samba_version_string() instead of SAMBA_VERSION_STRING in files that use no other macro from version.h instead of SAMBA_VERSION_STRING. * explicitly include "version.h" in those files that use more macros from "version.h" than just SAMBA_VERSION_STRING.
