* Fix bug #7863 - Unlink may unlink wrong file when hardlinks are involved.Jeremy Allison2011-01-251-93/+239
| | | | | | Do this by keeping a linked list of delete on close tokens, one for each filename that identifies a path to the dev/inode. Use the jenkins hash of the pathname to identify the correct token.
* Add uint32_t name_hash argument (currently unused) to get_file_infos().Jeremy Allison2011-01-251-0/+1
| | | | Will be used when we store more than one delete on close token.
* Add name_hash into the share mode entry struct (as yet only use for renames ↵Jeremy Allison2011-01-251-2/+15
| | | | to identify a specific path).

* Change to using TDB_INCOMPATIBLE_HASH (the jenkins hash) on allJeremy Allison2010-09-272-2/+2
| | | | | | | | | | TDB_CLEAR_IF_FIRST tdb's. For tdb's like gencache where we open without CLEAR_IF_FIRST and then with CLEAR_IF_FIRST if corrupt this is still safe to use as if opening an existing tdb the new hash will be ignored - it's only used on creating a new tdb not opening an old one. Jeremy.

* Remove more uses of "extern struct current_user current_user;".Jeremy Allison2010-03-121-10/+0
| | | | | | | | | | | | | Use accessor functions to get to this value. Tidies up much of the user context code. Volker, please look at the changes in smbd/uid.c to familiarize yourself with these changes as I think they make the logic in there cleaner. Cause smbd/posix_acls.c code to look at current user context, not stored context on the conn struct - allows correct use of these function calls under a become_root()/unbecome_root() pair. Jeremy.
* s3: Fix a long-standing problem with recycled PIDsVolker Lendecke2010-03-102-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Fix bug #6876 - Delete of an object whose parent folder does not have delete ↵Jeremy Allison2010-01-121-0/+3
| | | | | | | | | | rights fails even if the delete right is set on the object. Final fix for the vfs_acl_xattr and vfs_acl_tdb code. Ensure we can delete a file even if the underlying POSIX permissions don't allow it, if the Windows permissions do. Jeremy.

| | | | | | can_set_delete_on_close() is correctly called before any setting of the disposition bit (clean up the do_unlink() call). Jeremy.

* s3: Cache brlock.tdb entries for the fast read&write strict locking code pathVolker Lendecke2009-11-212-15/+65

* s3: Remove debug_ctx()Volker Lendecke2009-11-032-7/+7
| | | | | | | | smbd just crashed on me: In a debug message I called a routine preparing a string that itself used debug_ctx. The outer routine also used it after the inner routine had returned. It was still referencing the talloc context that the outer debug_ctx() had given us, which the inner DEBUG had already freed.
