Windows Vista RC1 and RC2 can't delete directory on Samba share
based on work by Joe Meadows <jmeadows@webopolis.com>.
Jeremy.
(This used to be commit 2dab892876)
Move more error code returns to NTSTATUS.
Client test code to follow... See if this
passes the build-farm before I add it into
3.0.25.

works - even with the strange "initial delete on close"
semantics. The "initial delete on close" flag isn't
committed to the share mode db until the handle is
closed, and is discarded if any real "delete on close"
was set. This allows me to remove the "initial_delete_on_close"
flag from the share db, and move it into a BOOL in files_struct.
Warning ! You must do a make clean after this. Cope with
the wrinkle in directory delete on close which is done
differently from files. We now pass all Samba4 smbtortute
BASE-DELETE tests except for the one checking that files
can't be created in a directory which has the delete on
close set (possibly expensive to fix).
Jeremy.
(This used to be commit f2df77a149)
Allow us to correctly refuse to set delete on close on a
non-empty directory. There are still some delete-on-close
wrinkles to be fixed, but I understand how to do that better
now. I'll fix this tomorrow.

a POSIX lock (applying a read-lock) and we overlap
pending read locks then send them an unlock message,
we may have allowed them to proceed.
Jeremy.
(This used to be commit a7a0b6ba50)
fix the messaging code to call the efficient calls :
save_re_uid()
set_effective_uid(0);
messaging_op
restore_re_uid();
instead of using heavyweight become_root()/unbecome_root()
pairs around all messaging code. Fixup the messaging
code to ensure sec_init() is called (only once) so that non-root
processes still work when sending messages.
This is a lighter weight solution to become_root()/unbecome_root()
(which swaps all the supplemental groups) and should be more
efficient. I will migrate all server code over to using this
(a similar technique should be used in the passdb backend
where needed).
Jeremy.
(This used to be commit 4ace291278)
of the lock array in order to delete them individually
it's also important to make a copy of the *size* of
this array. Otherwise the unlock decrements the termination
index of your for loop :-). Doh ! Big thanks to Volker
for showing me how to set up the build farm to track
this one down. This is not a 3.0.23a issue.
Jeremy.
(This used to be commit 2c82a159ae)
region between detecting a pending lock was needed
and when we added the blocking lock record. Make
sure that we hold the lock over all this period.
Removed the old code for doing blocking locks on
SMB requests that never block (the old SMBlock
and friends).
Discovered something interesting about the strange
NT_STATUS_FILE_LOCK_CONFLICT return. If we asked
for a lock with zero timeout, and we got an error
of NT_STATUS_FILE_LOCK_CONFLICT, treat it as though
it was a blocking lock with a timeout of 150 - 300ms.
This only happens when timeout is sent as zero and
can be seen quite clearly in ethereal. This is the
real replacement for old do_lock_spin() code.
Re-worked the blocking lock select timeout to correctly
use milliseconds instead of the old second level
resolution (far too coarse for this work).
Jeremy.
(This used to be commit b81d6d1ae9)
test. Phew - that was painful :-). But what it means
is that we now implement lock cancels and I can add
lock cancels into POSIX lock handling which will fix
the fast/slow system call issue with cifsfs !
Jeremy.
(This used to be commit f1a9cf075b)
requests. Maybe the Linux kernel OOM killer will
be kinder to smbd now :-). Back to tdbtorture
tests on cifsfs.
Jeremy.
(This used to be commit 1201383e7a)
We shouldn't allow this on the same smbd, but the cifsfs
client negotiates POSIX locks then sends Windows ones.
Doh ! Can't fix shipped client code....
Jeremy.
(This used to be commit 2f8cabe98d)
share_mode struct. Allows us to know the unix
uid of the opener of the file/directory. Needed
for info level queries on open files.
Jeremy.
(This used to be commit d929323d6f)
fsp pointers. Ensure we cope with this to pass Samba4
DENY tests (we used to pass these, there must have been
a regression with newer code). We now pass them.

db. Make this db self-cleaning on first read of entry after
open, and also on smbstatus -b call. Needs more testing when
I get back from Boston but passes valgrind at first look.
Jeremy.
(This used to be commit c665310963)
case it's in a performace critical path and it *hurts* us.
Go back to plain malloc/free with an explicit destructor
call.
Jeremy.
(This used to be commit 1c99aed563)
into 3.0. Also merge the new POSIX lock code - this
is not enabled unless -DDEVELOPER is defined.
This doesn't yet map onto underlying system POSIX
locks. Updates vfs to allow lock queries.
Jeremy.
(This used to be commit 08e52ead03)
this allows us to experiment with ensuring the tdb hash
size for our open files and locking db are appropriately
sized. Make the hash size larger by default (10007 instead
of 1049) and make the locking db hash size the same as the
open file db hash size.
Jeremy.
