We still have a few strange bugs with 64-bit locking values. I will
get traces.

(This used to be commit ff4c201d93e1f59ce61e9341f7f94ce92389ed7b)
functions so we can funnel through some well known functions. Should help greatly with
malloc checking.
HEAD patch to follow.

(This used to be commit 620f2e608f70ba92f032720c031283d295c5c06a)
tdb call, so there is no need to get the chainlock. This reduces the
number of tdb locking calls made on file IO
(This used to be commit 78e904c27b31d7123b521c446247d6ff558c84cc)
* remove corrupt tdb and shutdown (only for printing tdbs, connections,
sessionid & locking)
* decrement smbd counter in connections.tdb in smb_panic()
* various Makefile hack to get things to link
'max smbd processes' looks like it might be broken. The counter KEY is not
being set. Will look into that tomorrow.
(This used to be commit 6e22c5da929b6d9a4e32dc704c83112b2ad8fcfd)
for smb -> smb lock release). Adds new PENDING_LOCK type to lockdb
(does not interfere with existing locks).
Jeremy.
(This used to be commit 766928bbba1e597c9c2b12458dd8d37e6080593e)
major changes include:
- added NSTATUS type
- added automatic mapping between dos and nt error codes
- changed all ERROR() calls to ERROR_DOS() and many to ERROR_NT()
these calls auto-translate to the client error code system
- got rid of the cached error code and the writebmpx code
We eventually will need to also:
- get rid of BOOL, so we don't lose error info
- replace all ERROR_DOS() calls with ERROR_NT() calls
but that is too much for one night
(This used to be commit 83d9896c1ea8be796192b51a4678c2a3b87f7518)
many possible mem leaks, and segfaults fixed.
someone should port this fix to 2.2 also.
(This used to be commit fa8e55b8b465114ce209344965c1ca0333b84db9)
RPC code to merge with new passdb code.
Currently rpcclient doesn't compile. I'm working on it...
Jeremy.
(This used to be commit 0be41d5158ea4e645e93e8cd30617c038416e549)
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....
Jeremy.
(This used to be commit 9dea7b7c257db487f8ced7dad3fce92fba03ea91)
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.... :-)
Jeremy.
(This used to be commit f2a5ba3f0939f59097f0ef6a25f1cf9b5574f157)
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.
Jeremy.
(This used to be commit 74d42644e6e52808037975e909aa56c850838b76)
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.
Jeremy.
(This used to be commit 3f655de1c764b9ee1472a111621d4317f19f624d)
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.
(This used to be commit 6baa96bb466915cc17e8cbad50254d6bd47b967b)
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.
(This used to be commit 2746e5602e493e5b022764b4b839eb4d2f14363b)
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.
(This used to be commit 135855dbd3b8934a49229b81646cd4469acba926)
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.
(This used to be commit 49d7f0afbc1c5425d53019e234d54ddf205c8e9a)
the last piece was to use a smb timeout slightly larger than the
locking timeout in bloking locks to prevent a race
(This used to be commit 1b54cb4a33a65e62c2e3189b78ef073869a60c75)
