da3053048c Merge of new 2.2 code into HEAD (Gerald I hate you :-) :-). Allows new SAMR
RPC code to merge with new passdb code.
Currently rpcclient doesn't compile. I'm working on it...

7e4c4721b4 Changed to sourceforge tdb code. This includes spinlocks (so we now have
a --with-spinlocks option to configure, this does mean the on-disk tdb
format has changed, so 2.2alphaX sites will need to re-create their
tdb's. The upside is no more tdb fragmentation and a +5% on netbench.
Swings and roundabouts....

e522de4808 Using a structure for a tdb key can lead to insideous, hard
to find bugs. On 64 bit IRIX, structure packing means that
a
struct {
SMB_DEV_T dev /* 4 bytes */
SMB_INO_T ino /* 8 bytes */
}

has 4 bytes of padding between the two members. If you
don't null the memory before using it as a tdb key,
you randomly can't find keys depending on what is in
the padding. This caused me immense pain and was hard
to track down.... :-)

6d9ce38306 Fix for uninitialized memory read in brlock code. brl_locktest now needs
to correctly set the fnum, as the brl_conflict code looks at it.

c6230f6431 - clear dead locks at startup

20ce61ccc8 Fix for stacking locks in brlock and POSIX. Windows only allows a read lock
to overlay a write lock on the same fnum. When overlaying read locks onto
a write lock, the number of locks is counted, and the first unlock removes
the write lock and downgrades this to a read lock. Do the same when mapping
to POSIX.

9a5eb068ab Ok - this is the *third* implementation of this (third time's the charm :-).
This implementation keeps all POSIX lock records in a separate in memory
tdb database only known about in locking/posix.c. In addition, the pending
close fd's are also held in a tdb which has an array of fd's indexed by
device and inode.

The walk-split code uglyness has been moved to posix.c from brlock.c,
which is the only place that needs to know about it, and the extra
functions hacked into brlock to expose internal state have been removed.

This implementation passes smbtorture locktest4, the only thing I need
to check now for completeness is what to do about lock upgrade/downgrades
which Win32 allows under some *very* strange circumstances.

4b60a33c6f Ok - this is more subtle than it looks :-).
When a file is being closed, once it passes the fnum and tid tests then
the locking context should be ignored when removing all locks. This is
what is done in the brl close case, but when you have outstanding
POSIX locks, then you cannot remove all the brl locks in one go, you
have to get the lock list and call do_unlock individually. As this
uses global_smbpid as the locking context, you need to make sure
that this is set correctly for the specific lock being removed. I
now do this by storing the smbpid in each entry in the unlock list returned from
the query call. I removed the smbpid from fsp (not needed) and
things seem ok (even with the stupid smbpid tricks that smbtorture plays :-).

36db78feda Fixed subtle unlocking bug when a file is closed. We need to store the
smbpid used when a file was opened in the files_struct. Else we use
the wrong global_smbpid when we are closing the file and trying to
remove the brl locks - this causes the brl locks to be left when the
file is closed as the samba_context check fails.

e4d382750c Added the hard code :-).
HEAD should now map brl locks correctly into POSIX locks, including the
really nasty case of large range unlock.

There is a lot of pretty ASCII art in locking/brlock.c explaining
exactly how this code works. If it is unclear, please ask me.

bbe275e95b 1) added void* state argument to tdb_traverse. guess what! there were
two places i found where it was appropriate to _use_ that third argument,
in locking.c and brlock.c!  there was a static traverse_function and
i removed the static variable, typecast it to a void*, passed it to
tdb_traverse and re-cast it back to the traverse_function inside the
tdb_traverse function.  this makes the use of tdb_traverse() reentrant,
which is never going to happen, i know, i just don't like to see
statics lying about when there's no need for them.

as i had to do in samba-tng, all uses of tdb_traverse modified to take
the new void* state argument.

2) disabled rpcclient: referring people to use SAMBA_TNG rpcclient.
i don't know how the other samba team members would react if i deleted
rpcclient from cvs main.  damn, that code's so old, it's unreal.
20 rpcclient commands, instead of about 70 in SAMBA_TNG.

82af221e4a we now pass all byte range locking tests
the last piece was to use a smb timeout slightly larger than the
locking timeout in bloking locks to prevent a race

6c2a1fdf36 the bulk of the new byte range locking coode
it doesn't map to posix locks yet, that will come later.
