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.

The return values calculated by the callers were wrong anyways since
the new marshalling code does not set the local tdbs tdb error code.

This is the new implementation of ctdb transactions using the
global lock feature. It is needed by the current dbwrap_ctdb code.

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.

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.

In samba_kdc_trust_message2entry() on error, hdb_free_entry()
may end up trying to access uninitialized memory or double
free the hdb_entry.

"nt_response" structures
In some cases those structures are not initialised and the whole authentication
system crashes with a SIGSEGV. Bug discovered by Matthieu Patou in bug #6755.

Previously the "no_pass" and "no_pass2" variables weren't handled correctly.
Since at the initialisation of the "CredentialsOptions" we don't have any
password at all. Only afterwards we could get one through "set_password".
If a password is specified, use it. If no password is specified, consider the
use fo an input mask on STDOUT. But if the loadparm context contains one prefer
it over the input.

Create widelinks_warning(int snum) to cover the message needed in make_connection.

Looking at the winbind interface, we should only be using the bulk conversion calls.

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.

This way we avoid any chance that a configuration reload may turn
back on wide links when unix extensions are enabled.

Make sure we match the previous allow widelinks behavior, in that
non-root preexec scripts can create share directories for a share
definition.

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).

It's not fully clear what this ":dn" part means for us. What we know is that
older AD implementations (Windows Server 2000, 2003) need it to have extended
matches working in the expected way.
To be able to interoperate with s3's winbind and other tools I and gd decided
to transform this into a warning until we know what to do.
This should fix bug #6511.

this makes it easier to modify the script to set us at R2 level in
provision. We should make this a parameter.
