c00e4040bc s4:gensec/spengo: make sure we send the blob with the micListMech signature to the peer
We should even do this if the submech has no more data to send.

ae9f7857d5 r20107: don't segfault when the server didn't send a supportedMech in a negTokenTarg
this happens because we send 1.2.840.113554.1.2.2 before 1.2.840.48018.1.2.2
in the negTokenInit. And w2k's spnego code redirects us to use 1.2.840.48018.1.2.2
and then we start the our spnego engine with 1.2.840.48018.1.2.2 and in the then following
negTokenTarg w2k don't send the supportedMech (which means it aggrees in what we've choosen)

ba07fa43d0 r17197: This patch moves the encryption of bulk data on SASL negotiated security
contexts from the application layer into the socket layer.

This improves a number of correctness aspects, as we now allow LDAP
packets to cross multiple SASL packets.  It should also make it much
easier to write async LDAP tests from windows clients, as they use SASL
by default.  It is also vital to allowing OpenLDAP clients to use GSSAPI
against Samba4, as it negotiates a rather small SASL buffer size.

This patch mirrors the earlier work done to move TLS into the socket
layer.

Unusual in this pstch is the extra read callback argument I take.  As
SASL is a layer on top of a socket, it is entirely possible for the
SASL layer to drain a socket dry, but for the caller not to have read
all the decrypted data.  This would leave the system without an event
to restart the read (as the socket is dry).

As such, I re-invoke the read handler from a timed callback, which
should trigger on the next running of the event loop.  I believe that
the TLS code does require a similar callback.

In trying to understand why this is required, imagine a SASL-encrypted
LDAP packet in the following formation:

+-----------------+---------------------+
| SASL  Packet #1 | SASL Packet #2      |
----------------------------------------+
| LDAP Packet #1       | LDAP Packet #2 |
----------------------------------------+

In the old code, this was illegal, but it is perfectly standard
SASL-encrypted LDAP.  Without the callback, we would read and process
the first LDAP packet, and the SASL code would have read the second SASL
packet (to decrypt enough data for the LDAP packet), and no data would
remain on the socket.

Without data on the socket, read events stop.  That is why I add timed
events, until the SASL buffer is drained.

Another approach would be to add a hack to the event system, to have it
pretend there remained data to read off the network (but that is ugly).

In improving the code, to handle more real-world cases, I've been able
to remove almost all the special-cases in the testnonblock code.  The
only special case is that we must use a deterministic partial packet
when calling send, rather than a random length.  (1 + n/2).  This is
needed because of the way the SASL and TLS code works, and the 'resend
on failure' requirements.

44e601b5ad r13206: This patch finally re-adds a -k option that works reasonably.
From here we can add tests to Samba for kerberos, forcing it on and
off.  In the process, I also remove the dependency of credentials on
GENSEC.

This also picks up on the idea of bringing 'set_boolean' into general
code from jpeach's cifsdd patch.

b0fe5e6ade r11196: Clean up memory leaks (pointed out by vl), and handle the case where
the client doesn't guess correctly on the mech to use.  It must back
off and try the mech the server selected from the list.

I'm not particularly attached to our SPNEGO parser, so while I can't
easily use the SPNEGO application logic in Heimdal, I'm going to look
closely at using the asn1 routines to avoid some pain here.

f281d77824 r10291: The patch optionally (off by default, not available in all cases) allows
Samba to use the target principal name supplied in the mechTokenMIC of
an SPNEGO negTokenInit.

This isn't a great idea for security reasons, but is how Samba3 behaves,
and allows kerberos to function more often in some environments.  It is
only available for CIFS session setups, due to the ordering of the
exchange.

5edbeca141 r10153: This patch adds a new parameter to gensec_sig_size(), the size of the
data to be signed/sealed.  We can use this to split the data from the
signature portion of the resultant wrapped packet.

This required merging the gsskrb5_wrap_size patch from
lorikeet-heimdal, and fixes AES encrption issues on DCE/RPC (we no
longer use a static 45 byte value).

This fixes one of the krb5 issues in my list.

7e36c7e607 r9416: Cleanups inspired by jra's work to migrate Samba4's NTLMSSP code back
into Samba3.

The NTLMSSP sign/seal code now assumes that GENSEC has already checked
to see if SIGN or SEAL should be permitted.  This simplfies the code
ensures that no matter what the mech, the correct code paths have been
set in place.

Also remove duplication caused by the NTLMv2 code's history, and
document why some of the things a bit funny.

In SPNEGO, create a new routine to handle the negTokenInit creation.
We no longer send an OID for a mech we can't start (like kerberos on
the server without a valid trust account).

8a68f96f8c r7827: Add in-memory keytab to Samba4, using the new MEMORY_WILDCARD keytab
support in Heimdal.

This removes the 'ext_keytab' step from my Samba4/WinXP client howto.

In doing this work, I realised that the replay cache in Heimdal is
currently a no-op, so I have removed the calls to it, and therefore
the mutex calls from passdb/secrets.c.

This patch also includes a replacement 'magic' mechanism detection,
that does not issue extra error messages from deep inside the GSSAPI
code.

5c6dd5e800 r6800: A big GENSEC update:
Finally remove the distinction between 'krb5' and 'ms_krb5'.  We now
don't do kerberos stuff twice on failure.  The solution to this is
slightly more general than perhaps was really required (as this is a
special case), but it works, and I'm happy with the cleanup I achived
in the process.  All modules have been updated to supply a
NULL-terminated list of OIDs.

In that process, SPNEGO code has been generalised, as I realised that
two of the functions should have been identical in behaviour.

Over in the actual modules, I have worked to remove the 'kinit' code
from gensec_krb5, and placed it in kerberos/kerberos_util.c.

The GSSAPI module has been extended to use this, so no longer requires
a manual kinit at the command line.  It will soon loose the
requirement for a on-disk keytab too.

The general kerberos code has also been updated to move from
error_message() to our routine which gets the Heimdal error string
(which may be much more useful) when available.
