e4275a35a6 Fixed the (incorrect) paranioa fix I put in for the fcntl lock spin.
Don't delete a share mode that failed to remove the oplock (doh!),
just set the oplock entry to zero....

e6a6dee027 This is Jeremy pretending to be Volker, 'cos the
link from Seattle is having problems.
I've added 3 things here to work on the fcntl spin
problem.
1). Check *all* tdb return codes... :-).
2). If we're asking ourselves to break an oplock, and we can't
find a fsp pointer that matches the entry, this is a *logic bug*
and we should abort and panic so someone with gdb can pick up
the pieces.
3). After we've broken an oplock, ensure that the entry itself
has been removed, and if not remove it ourselves. This should
not be neccessary in a correctly working environmen,t, but will
provide an added layer of robustness in error situations.
4). I hate german keyboards :-) :-).

c786a4d89a Ensure we are very explicit about what we're comparing when
we're comparing structures (ie. don't just do a memcmp). I
don't think this will fix the fcntl spin issue, but it's a
"just in case" change.

6e7f03f9b9 This is a big, rather ugly patch. Whilst investigating the files not truncated
when copying to a full disk problem, I discovered that we were not allowing
the delete on close flag to be set properly, this led to other things, and
after investigation of the proper delete on close semantics and their relationship
to the file_share_delete flag I discovered there were some cases where we
weren't doing the deny modes properly. And this after only 5 years working
on them..... :-) :-).
So here's the latest attempt. I realised the delete on close flag needs to
be set across all smbds with a dev/ino pair open - in addition, the delete
on close flag, allow share delete and delete access requested all need to
be stored in the share mode tdb.
The "delete_on_close" entry in the fsp struct is now redundant and should
really be removed. This may also mean we can get rid of the "iterate_fsp"
calls that I didn't like adding in the first place. Whilst doing this patch,
I also discovered we needed to do the se_map_generic() call for file opens
and POSIX ACL mapping, so I added that also.
This code, although ugly, now passes the deny mode torture tests plus the
delete on close tests I added. I do need to add one more multiple connection
delete on close test to make sure I got the semantics exactly right, plus we
should also (as Andrew suggested) move to random testing here.

The good news is that NT should now correctly delete the file on disk
full error when copying to a disk :-).

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.

636f146abf Restructuring of vfs layer to include a "this" pointer - can be an fsp or
a conn struct depending on the call.
We need this to have a clean NT ACL call interface.
This will break any existing VFS libraries (that's why this is pre-release
code).
Andrew gets credit for this one :-) :-).

In addition - added Herb's WITH_PROFILE changes - Herb - please examine
the changes I've made to the smbd/reply.c code you added. The original
code was very ugly and I have replaced it with a
START_PROFILE(x)/END_PROFILE(x) pair using the preprocessor.
Please check this compiles ok with the --with-profile switch.

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.... :-)

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.

d009301464 Implemented the last (I hope:-) part of the locking puzzle, the reference
counting when Windows downgrades a write lock to a read lock, then reference
counts the unlocks to match the locks.

32d5416b6a split the username in the vuser structure into a separate

(unused at the moment).

This will be important shortly, as operation in appliance mode needs
the domain to be always carried with the username.

700f72453e - removed all our old wildcard matching code and replaced it with a
call to ms_fnmatch(). This also removes all the Win9X semantics stuff
and a bunch of other associated cruft.

- moved the stat cache code into statcache.c

- fixed the uint16 alignment requirements of ascii_to_unistr() and
  unistr_to_ascii()

- trans2 SMB_FIND_FILE_BOTH_DIRECTORY_INFO returns the short name as
  unicode always (at least thats what NT4 does)

- fixed some errors in the in-memory tdb code. Still ugly, but doesn't

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 :-).
