2011-10-11s3:locking: convert locking.c to use dbwrap wrapper functions onlyMichael Adam1-12/+31
Avoid direct use of the db_record and db_context structs.

2011-07-29s3:dbwrap: move db_open() to a file dbwrap_open.c of its own.Michael Adam1-0/+1
Also start new folder lib/dbwrap/ where dbwrap_open.c is stored and make the fallbacke implementation functoins non-static and create a dbwrap_private.h header file that contains their prototypes.
2011-06-20tdb_compat: Higher level API fixes.Rusty Russell1-1/+1
My previous patches fixed up all direct TDB callers, but there are a few utility functions and the db_context functions which are still using the old -1 / 0 return codes. It's clearer to fix up all the callers of these too, so everywhere is consistent: non-zero means an error. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2011-01-25Fix bug #7863 - Unlink may unlink wrong file when hardlinks are involved.Jeremy Allison1-93/+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.

Will be used when we store more than one delete on close token.

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.

2010-03-15We don't need to treat the token differently in the conn->admin_user case, ↵Jeremy Allison1-11/+0
it should already be pointing to a token with uid == 0. Jeremy.
2010-03-15Rever e80ceb1d7355c8c46a2ed90d5721cf367640f4e8 "Remove more uses of "extern ↵Jeremy Allison1-0/+10
struct current_user current_user;"." As requested by Volker, split this into smaller commits. Jeremy.
2010-03-12Remove more uses of "extern struct current_user current_user;".Jeremy Allison1-10/+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.
2010-03-10s3: Fix a long-standing problem with recycled PIDsVolker Lendecke1-1/+1
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
2010-01-12Fix bug #6876 - Delete of an object whose parent folder does not have delete ↵Jeremy Allison1-0/+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.
2009-12-02Remove unneeded argument from can_set_delete_on_close(). EnsureJeremy Allison1-9/+2
can_set_delete_on_close() is correctly called before any setting of the disposition bit (clean up the do_unlink() call). Jeremy.
2009-11-21s3: Cache brlock.tdb entries for the fast read&write strict locking code pathVolker Lendecke1-10/+8
For a netbench run this gains around 2% user-space CPU, fetching a 100MB file takes around 4% less.
