and finishes the trans2 conversion.

InBuffer/OutBuffer
The complete history of this patch can be found under
http://www.samba.org/~vlendec/inbuf-checkin/.
Jeremy, Jerry: If possible I would like to see this in 3.2.0. I'm only
checking into 3_2 at the moment, as it currently will slow down operations for
all non-converted (i.e. all at this moment) operations, as it will copy the
talloc'ed inbuf over the global InBuffer. It will need quite a bit of effort
to convert everything necessary for the normal operations an XP box does.
I have patches for negprot, session setup, tcon_and_X, open_and_X, close. More
to come, but I would appreciate some help here.

lock we know nothing about that we retry the lock every
10 seconds instead of waiting for the standard select
timeout. This is how we used to (and are supposed to)
work.

The majority of this patch passes a "struct messaging_context" down
there. No functional change, survives make test.

This changes "struct process_id" to "struct server_id", keeping both is

The idea is that we have blocking.c:brl_timeout as a timed
event that is present whenever we do have a blocking lock
pending. It fires brl_timeout_fn() which calls
process_blocking_lock_queue().
Whenever we make changes to blocking_lock_queue, we trigger
a recalc_brl_timeout() which sets a new brl_timout event if
necessary. This makes the call to
blocking_locks_timeout_ms() in setup_select_timeout()
unnecessary, this is implicitly done in
event_add_to_select_args() from the timed events.

void message_register(int msg_type,
void (*fn)(int msg_type, struct process_id pid,
- void *buf, size_t len))
+ void *buf, size_t len,
+ void *private_data),
+ void *private_data)
{
struct dispatch_fns *dfn;
So this adds a (so far unused) private pointer that is passed from
message_register to the message handler. A prerequisite to implement a tiny
samba4-API compatible wrapper around our messaging system. That itself is
necessary for the Samba4 notify system.
Yes, I know, I could import the whole Samba4 messaging system, but I want to
do it step by step and I think getting notify in is more important in this
step.

bytes returned" is less than the amount we want
to send, return what we can and set STATUS_BUFFER_OVERFLOW
(doserror ERRDOS,ERRbufferoverflow). Required by
OS/2 to handle EA's that are too large. It's hard
to test this in Samba4 smbtorture as the max data
bytes returned is hard coded at 0xffff (as it is
in the Samba3 client libraries also). I used a
custom version of Samba4 smbtorture to test this
out. Might add a "max data bytes" param to make
this testable in the build farm. Confirmed by
"Guenter Kukkukk (sambaos2)" <sambaos2@kukkukk.com>
and Andreas Taegener <atsamba11@eideltown.de>
that this fixes the issue.

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).

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).

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 !

then is the client supports it (current clients supported are Samba and
CIFSVFS - detected by the negprot strings "Samba", "POSIX 2" and a bare
"NT LM 0.12" string) then the setting of the per packet flag smb_flag
FLAG_CASELESS_PATHNAMES is taken into account per packet. This allows
the linux CIFS client to use Samba in a case sensitive manner.
Additional command in smbclient "case_sensitive", toggles the
flag in subsequent packets.
Docs to follow.

I was storing the mid of the oplock break - I should have been
storing the mid from the open. There are thus 2 types of deferred
packet sequence returns - ones that increment the sequence number
(returns from oplock causing opens) and ones that don't (change notify
returns etc). Running with signing forced on does lead to some
interesting tests :-).

0x80000000 -> 0xFFFFFFFF would fail as they were being cast
from IVAL (uint32) to SMB_OFF_T (off_t or off64_t, both *signed* types).
The sign extension would cause the offset to be treated as negative.
Thanks to Herb for helping me track this one down (IRIX is good for large
file tests :-).

"One of these locks is not like the others... One of these locks is not
quite the same" :-). When is a zero timeout lock not zero ? When it's
being processed by Windows 2000 of course.. This code change, ugly though
it is - completely fixes the foxpro/access multi-user file system database
problems that people have been having. I used a *wonderful* test program
donated by "Gerald Drouillard" <gerald@drouillard.ca> which allowed me
to completely reproduce this problem, and to finally determine the correct
fix. This also explains why Windows 2000 is *so slow* when responding to
the smbtorture lock tests. I *love* it when all these things come together
and finally make sense :-).
