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.

We would start the trans2 state, which is fine, but never pull the
expected reply off the packet queue.
I'm not sure if this is still a major problem after jra's recent 'no
duplicate mids on the list' change, but I think this is correct
anyway.
message, or we mess up the signing sequence number.... Also improve sign error
reporting. Also when deferring an open that had been deferred due to an oplock
break, don't re-add the mid to the pending sign queue or we increment the sequence
number twice and mess up signing again...
I can now bounce between 2 WinXP/Win2003 boxes opening Excel spreadsheets with
signing turned on and get correct "file in use" messages.

This patch re-adds support for 'optional' SMB signing. It also ensures that
we are much more careful about when we enable signing, particularly with
on-the-fly smb.conf reloads.
The client code will now attempt to use smb signing by default, and disable
it if the server doesn't correctly support it.

Add to the *start* of the list not the end of the list.
This ensures that the *last* send sequence with this mid
is returned by preference.
This can happen if the mid wraps and one of the early
mid numbers didn't get a reply and is still lurking on
the list.

solves the problem for me here, I can still successfully set up signing using
NTLMSSP against w2k3 and it does not show a signing error anymoe when the
password was wrong.
Jeremy, you might want to take a further look at it as this is not
particularly elegant.

- NTLM2 support in the server
- KEY_EXCH support in the server
- variable length session keys.
In detail:
- NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).
* This is known as 'NTLMv2 session security' *
(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes. We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)
This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed. This also needs to be turned off for
'security=server', which does not support this.
- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.
- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.
- There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation.
- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.
- The other big change is to allow variable length session keys. We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter. However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.
* This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *
- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe. This
should help reduce some of the 'it just doesn't work' issues.
- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer. (just allocate)
REMEMBER to make clean after this commit - I have changed plenty of data structures...
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 :-).
Jeremy.
Otherwise we find spurious mid sign records on reply_ntcancel calls (they cancel
by mid). That took a *lot* of tracking down. I still need to remove the mid
records from the sign state on reply_ntcancel to avoid leaking memory....
Jeremy.
bug with w2k. Turns out that when we're doing a trans/trans2/nttrans call
the MID and send_sequence_number and reply_sequence_number must remain constant.
This was something we got very wrong in earlier versions of Samba. I can now
get a directory listing from WINNT\SYSTEM32 with the older earlier parameters
for clilist.c
This still needs to be fixed for the server side of Samba, client appears to
be working happily now (I'm doing a signed smbtar download of an entire W2K3
image to test this :-).
Jeremy.
Server code *should* also work (I'll check shortly). May be the odd memory
leak. Problem was we (a) weren't setting signing on in the client krb5 sessionsetup
code (b) we need to ask for a subkey... (c). The client and server need to
ask for local and remote subkeys respectively.
Thanks to Paul Nelson @ Thursby for some sage advice on this :-).
Jeremy.
