that create dispositions that cause O_TRUNC break
oplocks. This simplifies the code - although we have
to keep separate the client requested access mask and
the access mask we actually use to open the file.

oplocks that were granted when we had released the lock. Fix
strange case where stat open grants a batch oplock on file
create, but grants no oplock on file open.

(This used to be commit b7374835e6ec0c98fc4020623f0a37c0c173b8aa)
no way to get all the cases where kernel oplocks are
on and we can't open the file and get the correct
semantics (think about the open with truncate with
an attribute only open - we'd need a vfs change to
add the truncate(fname, len) call). So always drop
the share mode lock before doing any real fd opens and
then re-acquire it afterwards. We're already dealing
with the race in the create case, and we deal with
any other races in the same way. Volker, please
examine *carefully* :-). This should fix the problems
people reported with kernel oplocks being on.

share_mode struct. Allows us to know the unix

for info level queries on open files.

This allows a requestor to set FORCE_OPLOCK_BREAK_TO_NONE
to ensure we don't break to level 2. Fixed a couple
of resource leaks in error paths in open_file_ntcreatex.

mid replies on path based set-eof trans2 calls.
Needs modification for HEAD (as in head open_file_ntcreateX
properly returns NTSTATUS - I'll fix this tomorrow my
time). Secondly it still fails the Samba4 RAW-OPLOCK
smbtorture because of an interesting case. Our oplock
code always returns "break to level 2" if it can.
In this case (path-based set-eof or set-allocation size
on an exclusive oplocked file) W2K3 always sends a
break-to-none. We send the break to none (from level2)
after we've done the write for eof or allocation size.
I need to work out some way of telling our break code
to always break to none (might need to extend the message
field).

This could be the cause of the perf. problem reported
between 3.0.14a and 3.0.2x. Lufthansa has *wireless*

is produced when a process exits abnormally.
First, we coalesce the core dumping code so that we greatly improve our
odds of being able to produce a core file, even in the case of a memory
fault. I've removed duplicates of dump_core() and split it in two to
reduce the amount of work needed to actually do the dump.
Second, we refactor the exit_server code path to always log an explanation
and a stack trace. My goal is to always produce enough log information
for us to be able to explain any server exit, though there is a risk
that this could produce too much log information on a flaky network.
Finally, smbcontrol has gained a smbd fault injection operation to test
the changes above. This is only enabled for developer builds.
(This used to be commit 56bc02d64498eb3faf89f0c5452b9299daea8e95)
because lck->num_share_modes != 0 doesn't mean that
there *are* other valid share modes. They may be
all marked "UNUSED" or be deferred open entries.
In that case don't downgrade the granted oplock to
level2 needlessly - a client can have an exclusive
oplock in this case. The original code handled this
correctly in the lck->num_share_modes == 0 case but
not in the case where there were no valid share modes
but lck->num_share_modes != 0. I'll clean up my
Samba4 torture tester for this and commit it tomorrow.
Jeremy.
(This used to be commit 306061c93d9181262298516fefd83444f5a65ce5)
The sad thing is the core of this bug fix is just
removing a paranoia "exit_server" call, as the
rest of the logic was already correct :-).
Lots of comments to explain the logic added.
I will look at adding tests to exercise this,
might be possible.
Jeremy.
(This used to be commit c2488db727e1a00f112be7b169de9e6208e311f3)
Remove check_for_pipe() - Volker was completely correct.
If it gets re-added it will be in a old open call path, not
in the generic code path.
Jeremy.
(This used to be commit 50c894a6e949d4d3579926650674f381a821a671)
honored (ie. the file gets deleted) for derectories when set at open
time - even though it doesn't show in the qfileinfo call. This is not
true of files.... (if anyone from the EU is listening, it's stuff like
this that makes CIFS non-documentable :-).
Jeremy.
(This used to be commit e2fc8a196a06f76aa47fabc30872c701a2f7ccec)
by saving the UNIX token used to set a delete on close flag,
and using it when doing the delete. libsmbsharemodes.so still
needs updating to cope with this change.
Samba4 torture tests to follow.

always linearize into little-endian. Should fix all
Solaris issues with this, plus provide a cleaner base
moving forward for cluster-aware Samba where smbd's
can communicate across different compilers/architectures
(eventually these message will have to go cross-machine).
Jeremy.
(This used to be commit d01824b78576a034428e1cef73868d1169057991)
oplocks across the cluster. Adapt Samba to it.
The gpfs API is called via libgpfs.so. This code is written with dlopen(), so
that you can compile on a system with gpfs installed and later on run on
systems without gpfs available.
So to actually make Samba call gpfs share mode calls you need to compile with
gpfs.h and libgpfs.so around and set 'gpfs share = yes' on the shares you
export from GPFS.

that have open file handles to allow them to correctly
implement delete on close. There is a further correctness
fix I'm intending to add to this to cope with different share
paths, but not right now...
Jeremy.
(This used to be commit 932e337db8788e75344e1c7cf1ef009d090cb039)
revving the minor version number for libsmbsharemodes (we
now have a new _ex interface that takes the share path
as well as the filename). Needed for #3303. Some code written
by SATOH Fumiyasu <fumiya@samba.gr.jp> included in the changes
to locking/locking.c. The smbstatus output is a bit of a mess
and needs overhauling...
Jeremy.
(This used to be commit 9d93af713f8520ca506730dd32aa2b994937eaba)
can treat them similarly to file opens (delete on
close, share mode violations etc.). This fixes bug
#3216 I will up the default hash size on the locking
db in a later commit as this means more entries.
Jeremy.

<alex@infobit.ru>. A fcbopen specific part of the code was erroneously
being called as part of the mainline open. Note, that this patch
superceeds and replaces the fix that Volker added for this bug
(which he added a Samba4 torture test for ) :
"Fix a race condition in Samba 3. If two files are opened simultaneously with
NTCREATEX_DISP_CREATE (create if not exists, else fail) they might end up with
two or more times NT_STATUS_OK as EEXIST is not correctly handled."
Jeremy.

NTCREATEX_DISP_CREATE (create if not exists, else fail) they might end up with
two or more times NT_STATUS_OK as EEXIST is not correctly handled.
Jeremy, please look closely at this. You can easily verify this by adding a
smb_msleep(100) to the top of open_file_ntcreate and run the new samba4
torture test. It does also happen without the msleep, but not as reliably.
Thanks,
Volker

tests on this as it's very late NY time (just wanted to get this work
into the tree). I'll test this over the weekend....
Jerry - in looking at the difference between the two trees there
seem to be some printing/ntprinting.c and registry changes we might
want to examine to try keep in sync.

to confirm this but in the meantime get it up and running.
