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.

checkin will pull this up to srvstr_get_path. At that point we can get more
independent of the inbuf, the base_ptr in pull_string will only be used
to satisfy UCS2 alignment constraints.
(This used to be commit 836782b07b)
when verifying a ticket from winbindd_pam.c.
I've found during multiple, fast, automated SSH logins (such
as from a cron script) that the replay cache in MIT's krb5
lib will occasionally fail the krb5_rd_req() as a replay attack.
There seems to be a small window during which the MIT krb5
libs could reproduce identical time stamps for ctime and cusec
in the authenticator since Unix systems only give back
milli-seconds rather than the micro-seconds needed by the
authenticator. Checked against MIT 1.5.1. Have not
researched how Heimdal does it.
My thinking is that if someone can spoof the KDC and TDS
services we are pretty hopeless anyways.

to all callers of smb_setlen (via set_message()
calls). This will allow the server to reflect back
the correct encryption context.

(This used to be commit 2d80a96120)
not just an NTLMSSP - grr. This complicates the re-use of
common client and server code but I think I've got it right.
Not turned on of valgrinded yet, but you can see it start
to take shape !
Jeremy.
(This used to be commit 60fc9c0aed)
to return a NT_STATUS_TIME_DIFFERENCE_AT_DC error to
a client when there's clock skew. Will help people
debug this. Prepare us for being able to return the
correct sessionsetupX "NT_STATUS_MORE_PROCESSING_REQUIRED"
error with associated krb5 clock skew error to allow
clients to re-sync time with us when we're eventually
able to be a KDC.
Jeremy.
(This used to be commit c426340fc7)
see this as a design flaw in data_blob() and it made me look in that routine.
Jeremy, revert or merge please :-)
Volker
(This used to be commit e7e6b8b5e0)
fragmented into "max xmit" size security blob
chunks. Bug #4400. Needs limits adding, and also
a client-side version.
Jeremy.
(This used to be commit aa69f2481a)
Vista sends the NTLMv2 blob by default in the tconX
packet. Make sure we save off the workgroup the user
was logged into on the client in the sessionsetupX
and re-use it for the NTLMv2 calc.
Jeremy.
(This used to be commit 45dcf62960)
logic in smbd/process.c. All interested (Volker,
Jerry, James etc). PLEASE REVIEW THIS CHANGE.
The logic should be identical but *much* easier
to follow and change (and shouldn't confuse Klockwork :-).
Jeremy.
(This used to be commit d357f8b335)
right now. r14112 broke it, in 3.0.22 register_vuid for security=share returns
UID_FIELD_INVALID which in current 3_0 is turned into an error condition. This
makes sure that we only call register_vuid if sec!=share and meanwhile also
fixes a little memleak.
Then I also found a crash in smbclient with sec=share and hostmsdfs=yes.
There's another crash with sec=share when coming from w2k3, but I need sleep
now.
Someone (jerry,jra?) please review the sesssetup.c change.
Thanks,
Volker
(This used to be commit 8059d0ae39)
prevents a nasty failure condition in winbindd's pam_auth where a tgt
and a service ticket could have been succefully retrieved, but just not
validated.
Guenther
(This used to be commit a75dd80c62)
changing the token generation. I *hate* this code!
Jerry, you have been looking at this as well, can you double-check that I did
not screw it up?
Thanks,
Volker
(This used to be commit 2765c4ff8d)
fail and we would still return success in the SMBsesssetup reply :-(
* Make sure to create the local token for the server_fino struct
in reply_spnego_kerberos() so that register_vuid() does not fail.
(how did this ever work?)
(This used to be commit 8dafa45b97)
setup comes in with the vc (virtual connection) field set to zero. This is
done by Windows, probably you can tweak that by some registry key.
This boolean option controls whether an incoming session setup
should kill other connections coming from the same IP. This matches
the default Windows 2003 behaviour.
Setting this parameter to yes becomes necessary when you have a flaky
network and windows decides to reconnect while the old connection
still has files with share modes open. These files become inaccessible
over the new connection.
The client sends a zero VC on the new connection, and Windows 2003
kills all other connections coming from the same IP. This way the
locked files are accessible again.
Please be aware that enabling this option will kill connections behind
a masquerading router.
Volker
(This used to be commit 5629ca1623)
Also remove the mem_ctx from the netsamlogon_cache_store() API.
Guenther, what should we be doing with the other fields in
the PAC_LOGON_INFO?
(This used to be commit 8bead2d282)
* remove redundant call to sub_set_smb_name() in session setup code.
* Fix lockup when running 'wbinfo -t' on a Samba PDC. Cause
was new authenticated session setup from winbindd which
resulted in a mangled username (machine_) that was not found
in the local files and so was queiued up to nss_winbindd.
Deadlock....
So now make sure to keep the trailing '$' for machine account
names when calling sub_set_smb_name().
