In librpc, always try SMB level authentication, even if trying
schannel, but allow fallback to anonymous. This should better
function with servers that set restrict anonymous.
There are too many parts of Samba that get, parse and modify the
binding parameters. Avoid the extra work, and add a binding element
to the struct dcerpc_pipe
The libnet vampire code has been refactored, to reduce extra layers
and to better conform with the standard argument pattern. Also, take
advantage of the new libnet_Lookup code, so we don't require the silly
'password server' smb.conf parameter.
To better support forcing traffic to be sealed for the vampire
operation, the dcerpc_bind_auth() function now takes an auth level
parameter.

dcerpc_interface_table struct rather then a tuple of interface
name, UUID and version.
This removes the requirement for having a global list of DCE/RPC interfaces,
except for these parts of the code that use that list explicitly
(ndrdump and the scanner torture test).
This should also allow us to remove the hack that put the authservice parameter
in the dcerpc_binding struct as it can now be read directly from
dcerpc_interface_table.
I will now modify some of these functions to take a dcerpc_syntax_id
structure rather then a full dcerpc_interface_table.

flag 'smb2' in the dcerpc binding string. This gives a pretty good

- removed the struct dcerpc_request_state as all the state
information is already available on the dcerpc_pipe structure, so just
use that
- added a single dcerpc_recv_data() handler for receiving packets
from the transport layer. This then does the initial decoding of
the dcerpc packet, and then looks at the packet type in order to
work out who to dispatch it to. This should allow in-flight async
rpc requests to still work while a new bind or alter context is
happening
- ensure that if the transport indicates the connection is dead that
any in-flight bind or alter context requests are given an error
- removed full_request_private and instead use separate bind_private
and alter_private pointers
- added a few comments for some bits I found hard to understand

requests. If it's
not there (it's not yet on *any* call... :-)), the rpc client strictly
sequences calls to an rpc pipe. Might need some more work on the exact
sequencing semantics when a pipe with both sync and async calls is actually
deployed, but I want it in for winbind simplification.

structure in ndr_push_*() and ndr_print_*(). The push and print
functions really should not modify the structure.
metze, to make this work I had to change your spoolss hand
marshaller. Can you please check it is OK? I think that the IN and OUT
sides of that function are not ever called on the same structure, so I
think that attempt at remembering the value by assigning to
r->in._offered was not doing anything anyway, but please correct me if
I have misunderstood it.
If you really do need to remember something on those structures I'd
suggest the ndr_token_store() and ndr_token_retrieve() functions,
which are used by pidl for just this sort of thing.

event_context for the socket_connect() call, so that when things that
use dcerpc are running alongside anything else it doesn't block the
whole process during a connect.
Then of course I needed to change any code that created a dcerpc
connection (such as the auth code) to also take an event context, and
anything that called that and so on .... thus the size of the patch.
There were 3 places where I punted:
- abartlet wanted me to add a gensec_set_event_context() call
instead of adding it to the gensec init calls. Andrew, my
apologies for not doing this. I didn't do it as adding a new
parameter allowed me to catch all the callers with the
compiler. Now that its done, we could go back and use
gensec_set_event_context()
- the ejs code calls auth initialisation, which means it should pass
in the event context from the web server. I punted on that. Needs fixing.
- I used a NULL event context in dcom_get_pipe(). This is equivalent
to what we did already, but should be fixed to use a callers event
context. Jelmer, can you think of a clean way to do that?
I also cleaned up a couple of things:
- libnet_context_destroy() makes no sense. I removed it.
- removed some unused vars in various places

- added support for "spnego" in binding strings. This enables SPNEGO
auth in the dcerpc client code, using as many allter_context calls as
are needed

dcerpc_alter_context and multiple context_ids in the dcerpc client
library.
This stage does the following:
- split "struct dcerpc_pipe" into two parts, the main part being "struct dcerpc_connection", which
contains all the parts not dependent on the context, and "struct dcerpc_pipe" which has
the context dependent part. This is similar to the layering in libcli_*() for SMB
- disable the current dcerpc_alter code. I've used a #warning until i
get the 2nd phase finished. I don't know how portable #warning is, but
it won't be long before I add full alter context support anyway, so it won't last long
- cleanup the allocation of dcerpc_pipe structures. The previous code
was quite awkward.

rather then a large table in librpc/gen_ndr/tables.c. This will allow us
to only link in only the required gen_ndr files (speeds up linking quite a
bit, makes binaries smaller).
Each gen_ndr_* file now has a init function that calls the init functions
of the interfaces it contains. I did it this way to keep pidl's code simple,
though it might hurt startup time a bit. I'd be happy to change it if
people like one function better.

server. CONNECT security uses NTLMSSP, but does not do any signing or
sealing (or equivalently, its like signing, but with a zero filled
checksum).

This means that 'require NTLMv2 session security' now works for RPC
pipe signing. We don't yet have sealing, but it can't be much further.
This is almost all tridge's code, munged into a form that can work
with the GENSEC API.
This commit also includes more lsakey fixes - that key is used for all
DCE-RPC level authenticated connections, even over CIFS/ncacn_np.
No doubt I missed something, but I'm going to get some sleep :-)

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.

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.

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.
