9f53b61f06 CVE-2013-4496:samr: Remove ChangePasswordUser
This old password change mechanism does not provide the plaintext to
validate against password complexity, and it is not used by modern
clients.  It also has quite difficult semantics to handle regarding
password lockout.

The missing features in both implementations (by design) were:

 - the password complexity checks (no plaintext)
 - the minimum password length (no plaintext)

Additionally, the source3 version did not check:

 - the minimum password age
 - pdb_get_pass_can_change() which checks the security
   descriptor for the 'user cannot change password' setting.
 - the password history
 - the output of the 'passwd program' if 'unix passwd sync = yes'.

Finally, the mechanism was almost useless, as it was incorrectly
only made available to administrative users with permission
to reset the password.  It is removed here so that it is not
mistakenly reinstated in the future.

168627e187 s3-kerberos: remove print_kdc_line() completely.
Just calling print_canonical_sockaddr() is sufficient, as it already deals with
ipv6 as well. The port handling, which was only done for IPv6 (not IPv4), is
removed as well. It was pointless because it always derived the port number from
the provided address which was either a SMB (usually port 445) or LDAP
connection. No KDC will ever run on port 389 or 445 on a Windows/Samba DC.
Finally, the kerberos libraries that we support and build with, can deal with
ipv6 addresses in krb5.conf, so we no longer put the (unnecessary) burden of
resolving the DC name on the kerberos library anymore.

925625b528 dbwrap_ctdb: avoid smbd/ctdb deadlocks: check whether we can work locally in db_ctdb_parse_record()
If the same process tries to re-lock the same record
it has already locked, don't go to the ctdbd again.

There are situations where we already have a lock on a record
and then do a dbwrap_parse_record() on that record, for instance
in locking code:

do_lock()
  -> grabs lock on brl record with brl_get_locks()
    -> calls brl_lock()
      -> calls brl_lock_posix or _windows_default()
        -> calls contend_level2_oplocks_begin()
          -> calls brl_locks_get_read_only()
            -> calls dbwrap_parse_record on the same brl record as above

In the local (tdb) case, this is not a problem, because
identical fcntl locks in the same process don't contend each other,
but calling out to ctdb for this lets smbd and ctdb deadlock.

db_ctdb_fetch_lock() already correclty checks first
whether we can simply try to lock locally. But db_ctdb_parse_record()
failed to do so for empty records, i.e. records that only
consist of the ctdb record header. (These can be deleted records
but can also be freshly created and still empty records.)

This patch lets db_ctdb_parse_record() not skip local access
for empty records, hence fixing the deadlock.

PLAN: In the long run, it would be better to solve this
generically on the dbwrap_layer, i.e. root the notion of
an already locked record there, and skip any call to the
db (tdb or ctdb backend) if we have it. This would also
solve the problem for all calls like fetch_locked, parse_record
and possibly others.  But this is the urgent fix for now.

abf08ed544 s3: smbd: Ensure brl_get_locks_readonly() always returns a valid struct byte_range_lock even if there are no locks.
brl_get_locks_readonly() currently returns NULL when it can't
find any byte range locks on the file. This is an error - it
should return a valid struct byte_range_lock containing num_locks == 0
so it can be cached.

Returning NULL when there are no locks causes POSIX lock
tests to fail returning NT_STATUS_NO_MEMORY (as it thinks
it can't allocate the struct) instead of NT_STATUS_OK.
