bytes to make sure they are zero. Non-zero values usually indicate one
of two things:
- the server is leaking data through sending uninitialised memory
- we have mistaken a real field in the IDL for padding
to differentiate between the two you really need to run with
"print,padcheck" and look carefully at whether the non-zero pad bytes
are random or appear to be deliberate.

The fix uses the new talloc_increase_ref_count() function in an
interesting way. I suspect this sort of technique will become quite
common.

use readx/writex instead of the more efficient SMBtrans calls. This
patch restores the efficiency by using SMBtrans when possible.

generate a separate *_send() async function for every RPC call, and
there is a single dcerpc_ndr_request_recv() call that processes the
receive side of any rpc call. The caller can use
dcerpc_event_context() to get a pointer to the event context for the
pipe so that events can be waited for asynchronously.
The only part that remains synchronous is the initial bind
calls. These could also be made async if necessary, although I suspect
most applications won't need them to be.

The bug (found by tridge) is that Win2k3 is being tighter about the
NTLMSSP flags. If we don't negotiate sealing, we can't use it.
We now have a way to indicate to the GENSEC implementation mechanisms
what things we want for a connection.

This version does the following:
1) talloc_free(), talloc_realloc() and talloc_steal() lose their
(redundent) first arguments
2) you can use _any_ talloc pointer as a talloc context to allocate
more memory. This allows you to create complex data structures
where the top level structure is the logical parent of the next
level down, and those are the parents of the level below
that. Then destroy either the lot with a single talloc_free() or
destroy any sub-part with a talloc_free() of that part
3) you can name any pointer. Use talloc_named() which is just like
talloc() but takes the printf style name argument as well as the
parent context and the size.
The whole thing ends up being a very simple piece of code, although
some of the pointer walking gets hairy.
So far, I'm just using the new talloc() like the old one. The next
step is to actually take advantage of the new interface
properly. Expect some new commits soon that simplify some common
coding styles in samba4 by using the new talloc().

This implements gensec for Samba's server side, and brings gensec up
to the standards of a full subsystem.
This means that use of the subsystem is by gensec_* functions, not
function pointers in structures (this is internal). This causes
changes in all the existing gensec users.
Our RPC server no longer contains it's own generalised security
scheme, and now calls gensec directly.
Gensec has also taken over the role of auth/auth_ntlmssp.c
An important part of gensec, is the output of the 'session_info'
struct. This is now reference counted, so that we can correctly free
it when a pipe is closed, no matter if it was inherited, or created by
per-pipe authentication.
The schannel code is reworked, to be in the same file for client and
server.
ntlm_auth is reworked to use gensec.
The major problem with this code is the way it relies on subsystem
auto-initialisation. The primary reason for this commit now.is to
allow these problems to be looked at, and fixed.
There are problems with the new code:
- I've tested it with smbtorture, but currently don't have VMware and
valgrind working (this I'll fix soon).
- The SPNEGO code is client-only at this point.
- We still do not do kerberos.

This layer is used for DCERPC security, as well as ntlm_auth at this
time. It expect things like SASL and the CIFS layer to use it as
well.
The particular purpose of this layer is to introduce SPENGO, which
needs generic access to the actual implementation mechanisms.
Schannel, due to it's 'interesting' setup properties is in GENSEC, but
is only in the RPC code.

Samba's NTLMSSP code is now fully talloc based, which should go a long
way to cleaning up the memory leaks in this code. This also avoids a
lot of extra copies of data, as we now allocate the 'return' blobs on
a caller-supplied context.
I have also been doing a lot of work towards NTLM2 signing and
sealing. I have this working for sealing, but not for the verifier
(MD5 integrity check on the stream) which is still incorrect.
(I can aim a rpcecho sinkdata from a Win2k3 box to my server, and the
data arrives intact, but the signature check fails. It does however
match the test values I have...).
The new torture test is cludged in - when we get a unit test suite
back, I'll happliy put it in the 'right' place....

- added schannel sign and sign/seal support to the dcerpc client
code. You select it with binding options of "schannel,sign" or
"schannel,seal".

This adds support for bigendian rpc in the client. I have installed
SUN pcnetlink locally and am using it to test the samba4 rpc
code. This allows us to easily find places where we have stuffed up
the types (such as 2 uint16 versus a uint32), as testing both
big-endian and little-endian easily shows which is correct. I have now
used this to fix several bugs like that in the samba4 IDL.
In order to make this work I also had to redefine a GUID as a true
structure, not a blob. From the pcnetlink wire it is clear that it is
indeed defined as a structure (the byte order changes). This required
changing lots of Samba code to use a GUID as a structure.
I also had to fix the if_version code in dcerpc syntax IDs, as it
turns out they are a single uint32 not two uint16s.
The big-endian support is a bit ugly at the moment, and breaks the
layering in some places. More work is needed, especially on the server
side.

I have recoded the core dcerpc packet structures (all the PDUs etc) in
terms of IDL, which means we now use pidl to generate all the code for
handling the most basic dcerpc packets. This is not normally possible
as it isn't completely valid NDR, but pidl has a number of extensions
that make it quite easy.
This also means we get the server side dcerpc
marshalling/unmarshalling code for free.

* don't consider not doing lsa_QueryInfoPolicy level 11 a failure
(w2k3 doesn't have this level, w2k does)
* on a NDR validation failure dump the failed data at level 3
(This used to be commit 9d5078962f0f8aef3360dea4c4774cf8de1fdc26)

* added a NDR validator. The way it works is that when the
DCERPC_DEBUG_VALIDATE_* flags are set the dcerpc system will
perform NDR buffer validation. On sending a request the packet is
first marshalled, then unmarahslled, then marshalled again, and it is
confirmed that the two marshalling results are idential. This
ensures that our pull and push routines are absolutely in sync, so
that we can be very confident that if a routine works in the client
then the corresponding routine must work on the server side. A
similar validation is performed on all replies.
* a result of this change is that pidl is fussier about the [ref]
tag. You can only use it on pointers (which is the only place it
makes sense)
* fixed a basic alignment bug in the push side of the NDR code
* added server side pull/push support. Our dcerpc system is now fully
ready to be used on the server side.
* fixed the relative offset pointer list. It must be traversed in
reverse order on push
* added automatic value setting for the size parameter in outgoing
SdBuf structures.
* expanded the ndr debugging code to always give a message on any
failure
* fixed the subcontext push code
* fixed some memory leaks in smbtorture RPC tests
