2010-02-12s3:dbwrap_ctdb: fix db_ctdb_fetch_db_seqnum_from_db() when NT_STATUS_NOT_FOUND.Michael Adam1-1/+5
Don't treat this as an error but return seqnum 0 instead. Michael

2010-02-12s3:dbwrap_ctdb: maintain a database sequence number that bumps in transactionsMichael Adam1-5/+116
For persistent databases, 64bit integer is kept in a special record __db_sequence_number__. This record is incremented with each completed transaction. The retry mechanism for failing TRANS3_COMMIT controls inside the db_ctdb_transaction_commit() function now relies one a modified behaviour of ctdbd's treatment of persistent databases in recoveries. Recently, a special treatment for persistent databases had been introduced in ctdb (1.0.108) to work around the problems with the orinal design of persistent transactions. Now with the rewrite we need to revert to the old behaviour that ctdb always takes the newest copies of all records. This change also paves the way for a next step, which will make recovery use the db seqnum to tell which node has the newest copy of a persistent db and use that node's copy. This will greatly reduce the amount of data transferred with each recovery. Michael
2010-02-12s3:dbwrap_ctdb: change db_ctdb_transaction_store() to return NTSTATUS.Michael Adam1-18/+12
The return values calculated by the callers were wrong anyways since the new marshalling code does not set the local tdbs tdb error code. Michael

2010-02-12build: Add a configure check for CTDB_CONTROL_TRANS3_COMMIT.Michael Adam1-0/+17
This is the new implementation of ctdb transactions using the global lock feature. It is needed by the current dbwrap_ctdb code. Michael

2010-02-12s3:dbwrap_ctdb: start rewrite of transactions using the global lock (g_lock)Michael Adam1-320/+160
This simplifies the transaction code a lot: * transaction_start essentially consists of acquiring a global lock. * No write operations at all are performed on the local database until the transaction is committed: Every store operation is just going into the marshall buffer. * The commit operation calls a new simplified TRANS3_COMMIT control in ctdb which rolls out thae changes to all nodes including the node that is performing the transaction.

2010-02-12s3: Implement global locks in a g_lock tdbVolker Lendecke11-7/+950
This is the basis to implement global locks in ctdb without depending on a shared file system. The initial goal is to make ctdb persistent transactions deterministic without too many timeouts.

2010-02-11Final part of jumbo patch for bug #7104 - "wide links" and "unix extensions" ↵Jeremy Allison1-0/+12
are incompatible. Volker pointed out that the preexec scripts get passed the conn->connectpath as a parameter, so call canonicalize_connect_path() both *before* and after the preexec scripts. Ignore errors on the call before the preexec scripts, as the path may not exist until created by the preexec scripts. Jeremy.
2010-02-11Introduce lp_safe_widelinks()Simo Sorce5-5/+24
This way we avoid any chance that a configuration reload may turn back on wide links when unix extensions are enabled.
2010-02-11Fine changes to previous fix for bug #7104 - "wide links" and "unix ↵Jeremy Allison1-20/+18
extensions" are incompatible. Make sure we match the previous allow widelinks behavior, in that non-root preexec scripts can create share directories for a share definition. Jeremy
2010-02-11Suplementary patch for bug #7104 - "wide links" and "unix extensions" are ↵Jeremy Allison1-27/+28
incompatible. Bug reported by Ralf Zimmermann <r.zimmermann@siegnetz.de>. Reproduced by jra. If the target directory of a share doesn't exist, but is designed to be created by a "root preexec" script call, then the widelinks check is done too early - thus preventing the user from connecting to the share. Fix is to re-arrange the order of checks in make_connection_snum() to always do the following order of operations: (1). Turn off wide links if unix extensions = yes. (2). Call any root preexec scripts. (3). Canonicalize the share path to remove any symlinks (ie. end up with the realpath in the connection_struct). Jeremy.

2010-02-11s3-spoolss: implement spoolss_EnumJobs level 3.Günther Deschner1-0/+76
Level 3 has been added with NT 4.0 and Windows 7 (at least 64bit version) makes use of it in order to display queued jobs. Windows 7 will *not* fall back to level 2 if we just return WERR_UNKNOWN_LEVEL, instead there will be no printjobs displayed at all. Guenther

2010-02-10util: rewrite dlinklist.h so that DLIST_ADD_END() is O(1)Andrew Tridgell1-59/+111
This changes the meaning of the ->prev pointer in our doubly linked lists to point at the end of the list from the front of the list. That allows us to implement DLIST_ADD_END() and related functions in O(1) time, which can be a huge saving in many places in Samba. This also means that the 'type' argument to various DLIST_*() macros is no longer needed, but I have left it in for now to keep the patchset small, which will make it easier to revert if any problems are found. In the future we should remove the 'type' arguments. (jra. Move the one use of DLIST_TAIL over to the new macros).

2010-02-10Revert "Change the default of "nmbd bind explicit broadcast" to "no""Jeremy Allison1-3/+3
This reverts commit 84fba3c1bc962804259f201d465acfdf0cd3c6a8. Now we have a "processed packet queue" in nmbd we can go back to doing this by default. Jeremy.
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.

until the double processing problem in bug #7118 is fixed. Jeremy.
