* s3: Make sure our CLEAR_IF_FIRST optimization works for serverid.tdbVolker Lendecke2010-03-251-0/+4
| | | | | | In the child, we fully re-open serverid.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.
* s3: Make sure our CLEAR_IF_FIRST optimization works for the notify tdbsVolker Lendecke2010-03-251-0/+4
| | | | | | The notify tdb files are opened at tconX time, which leads to one fcntl lock for CLEAR_IF_FIRST detection per smbd. This opens the tdbs in the parent and holds it, so that tdb_reopen_all correctly catches the CLEAR_IF_FIRST bit.

* s3: Add "log writeable files on exit" parameterVolker Lendecke2010-03-221-0/+31
| | | | | | | This boolean option controls whether at exit time the server dumps a list of files with debug level 0 that were still open for write. This is an administrative aid to find the files that were potentially corrupt if the network connection died.

* s3: Fix a long-standing problem with recycled PIDsVolker Lendecke2010-03-101-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* s3-smbd: add a rate limited cleanup of brl, connections and locking dbAndrew Tridgell2010-02-051-6/+42
| | | | | | | | | | | On unclean shutdown we can end up with stale entries in the brlock, connections and locking db. Previously we would do the cleanup on every unclean exit, but that can cause smbd to be completely unavailable for several minutes when a large number of child smbd processes exit. This adds a rate limited cleanup of the databases, with the default that cleanup happens at most every 20s

* s3/smbd: open the share_info.tdb on startup instead of tconxSteven Danneman2009-08-261-0/+9
| | | | | | | | This is a small performance optimization. Instead of opening the tdb on every smb connection in the forked child process, we now open it in the parent and share the fd. This also reduces the total fd usage in the system.

* Make gencache more stableVolker Lendecke2009-07-151-0/+1
| | | | | | | | | | 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.
* s3: forward MSG_DEBUG from smbd parent to all childrenAravind Srinivasan2009-06-221-14/+25
| | | | | | | | | | | | | | | | | | | Before 3.3, an smbcontrol debug message sent to the target "smbd" would actually be sent to all running processes including nmbd and winbindd. This behavior was changed in 3.3 so that the "smbd" target would only send a message to the process found in smbd.pid, while the "all" target would send a message to all processes. The ability to set the debug level of all processes within a single daemon, without specifying each pid is quite useful. This was implemented in winbindd in 065760ed. This patch does the same thing for smbd. Upon receiving a MSG_DEBUG the parent smbd will rebroadcast it to all of its children. The printing process has been added to the list of smbd child processes, and we now always track the number of smbd children regardless of the "max smbd processes" setting.

* s3: Allow child processes to exit gracefully if we are out of fdsMarc VanHeyningen2009-05-271-6/+13
| | | | | | | | | | 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>

* S3: Stop creating SMBD cores when failing to create a pipe.todd stecher2009-02-181-0/+4
| | | | | | This was uncovered when the MAX FD limit was hit, causing an instant core and invoking error reporting. This fix causes SMBD to exit, but without building a core.

| | | | | | This commit adds a configure argument which allows for setting MADV_PROTECT in the madvise() API. With this enabled the kernel won't kill SMBD when it's running low on memory.
