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.

fd_close now calls fd_close_posix() directly.
set_posix_lock/release_posix_lock() now handle the reference counting.
More changes due when this gets moved to the file locking/posix.c

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 :-).
Jeremy.

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.
Jeremy.

removed from the smbd/open.c code.
We now use a dlink list of structures indexed by dev/inode to store
all pending fd's for close. This could be rewritten to use lib/hash.c
if this is discovered to be too slow in use.
Andrew, please take a look and let me know if this is what you
had in mind.

test. Was miscounting posix locks, plus was not taking into account
the case where other_fsp == fsp in the 'move locks' case. DOH ! This
code will be re-written anyway :-).

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.
Jeremy.

open on the same dev/inode pair with existing POSIX locks.
This is done at the smbd/open layer, so smbd just calls fd_close() and
the transfer of any open fd's is done under the covers of fd_close().
When an fsp is closed and no other fsp's open on the same dev/inode
pair have existing POSIX locks then all fd's associated with this fsp
are closed.
Now only the hard part of doing the POSIX range unlock code when read
locks overlap remains for full POSIX/SMB lock integration....

new open mechanism Andrew & I discussed.
config.sub:
configure: Included the QNX patch.
include/vfs.h:
smbd/vfs-wrap.c:
smbd/vfs.c: Added ftruncate vfs call (needed).
Note that we will also need locking calls in the vfs (to be added).
lib/util_unistr.c:
nmbd/nmbd_processlogon.c: Fix for NT domain logons causing nmbd to core dump.
Also fix for sidsize DOS bug.
locking/locking.c: Check value of ret before using it for memdup.
printing/printing.c: Convert print_fsp_open to return an allocated fsp.
rpc_server/srv_lsa.c: Fix for NT domain logons.
I have removed all use of lp_share_modes() from the code (although I
left the parameter in the table for backwards compatibility). It no longer makes
sense for this to exist.
smbd/close.c: Removed lp_share_modes().
smbd/fileio.c: Fixed parameters to unlock_share_entry call in panic code.
smbd/files.c: Correctly set the unix_ERR_code to ERRnofids on fsp allocation fail.
smbd/nttrans.c:
smbd/reply.c:
smbd/trans2.c: Changed all occurrences of open_file_shared/open_directory/
open_file_stat to return an fsp from the call.
smbd/open.c: Changed all occurrences of open_file_shared/open_directory/
open_file_stat to return an fsp from the call.
In addition I have fixed a long standing race condition in the deny mode
processing w.r.t. two smbd's creating a file. Andrew, please note that
your original idea of using open with O_EXCL in this case would not work
(I went over the races very carefully) and so we must re-check deny modes
*after* the open() call returns. This is because there is a race between
the open with O_EXCL and the lock of the share mode entry. Imagine the
case where the first smbd does the open with O_EXCL and a deny mode of DENY_ALL,
but is pre-empted before it locks the share modes and creates the deny
mode entry for DENY_ALL. A second smbd could then come in with O_RDONLY
and a deny mode of DENY_NONE and the two opens would be allowed.
The *only* way to fix this race is to lock the share modes after the
open and then do the deny mode checks *after* this lock in the case
where the file did not originally exist.
This code will need extensive testing but seems to initially work.
Jeremy.

printing/printing.c: Cast tdb_delete to (tdb_traverse_func) to stop warning.
tmpfile gives mirror warning.
smbd/groupname.c: Remember to file_lines_free() on exit.
tdb/tdb.h: Add tdb_traverse_func typedef.

include/includes.h: Added SMB_BIG_UINT_BITS.
lib/util.c: Removed align2/align4 - use macros.
libsmb/namequery.c: Use ALIGN2.
locking/locking.c: Replace do_lock, do_unlock, args with SMB_BIG_UINT, not SMB_OFF_T.
Needed to move to hiding POSIX locks at a lower layer.
nmbd/nmbd_processlogon.c: Use ALIGN2/ALIGN4 macros.
smbd/blocking.c: Replace do_lock, do_unlock, args with SMB_BIG_UINT, not SMB_OFF_T.

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.

the last piece was to use a smb timeout slightly larger than the
locking timeout in bloking locks to prevent a race

note the ugly global_smbpid - I hope that won't bethere for long, I
just didn't want to do two lots of major surgery at the one time.
Using global_smbpid avoids the big change of getting rid of our
inbuf/outbuf interface to reply routines. I'll do that once the
locking stuff passes all tests.

this means "nmblookup -S" now always works, even with broken servers
the database stores all unexpected replies and these can be accessed
by any client.
while doing this I cleaned up a couple of functions, and put in place
a better trn_id generator. in most places the code got quite a bit
simpler due to the addition of simple helper functions.
I haven't yet put the code in to take advantage of this for pdc
replies - that will be next. Jeremys pdc finding code will then work :)

- added TDB_CLEAR_IF_FIRST flag to clear the database if this is the
first attached process. Useful for non-persistent databases like our
locking area (this will also make upgrades to new database layouts easier)
- use lock_path() in a couple of places
- leave connections database open while smbd running
- cleaned up some tdb code a little, using macros for constants

instead of either sysv or mmap shared memory or lock files.
this means we can now completely remove
locking_shm.c
locking_slow.c
shmem.c
shmem_sysv.c
and lots of other things also got simpler
locking.c got a bit larger, but is much better compartmentalised now

semantics.
This was trickier than it looks :-). Check out the new DELETE_ON_CLOSE
flag in the share modes and the new code that iterates through all open
files on the same device and inode in files.c and trans2.c
Also changed the code that modifies share mode entries to take
generic function pointers rather than doing a specific thing so
this sort of change should be easier in the future.

painstakingly put in :)
This gets rid of most of the #ifdef LARGE_SMB_INO_T ifdefs around
DEBUG() statements. We just use %.0f in all cases. Makes the code a
bit easier to read :)

include/smb.h: Moved old typedefs of uint8 etc. into include/includes.h where
all the other defines live (changed them from typedefs to
defines).
Other changes : changed from using uint32 to SMB_DEV_T and SMB_INO_T
in preparation for moving to size independed (ie. 64 bit clean) device
and inode access. Stat call wrapper comes next :-).

the head of an SMB request (ie. are part of a chain) will not be queued -
this will be fixed when we move to the new chain code. In practice, this
doesn't seem to cause much of a problem (in my admittedly limited testing)
bug a debug level zero message will be placed in the log when this
happens to help determine how real the problem is.

Connections[] is now a local array in server.c
I might have broken something with this change. In particular the
oplock code is suspect and some .dll files aren't being oplocked when
I expected them to be. I'll look at it after I've got some sleep.
