aca6a1e1ee r1993: Allow WinXP domain logon to progress a bit further (it seems broken for me).
Fix indent, and add a few more useful debug messages.

Send a fault, if the bind is not accepted - don't just leave the client hanging.

b83ba93eae r1983: a completely new implementation of talloc
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().

45a85bdd35 r1486: commit the start of the generic server infastructure
the idea is to have services as modules (smb, dcerpc, swat, ...)

the process_model don't know about the service it self anymore.

TODO:
- the smbsrv should use the smbsrv_send function
- the service subsystem init should be done like for other modules
- we need to have a generic socket subsystem, which handle stream, datagram,
  and virtuell other sockets( e.g. for the ntvfs_ipc module to connect to the dcerpc server
  , or for smb or dcerpc or whatever to connect to a server wide auth service)
- and other fixes...

NOTE: process model pthread seems to be broken( but also before this patch!)

dc9f55dbec r1294: A nice, large, commit...
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.

8087d844ef r995: - renamed many of our crypto routines to use the industry standard
names rather than our crazy naming scheme. So DES is now called
  des_crypt() rather than smbhash()

- added the code from the solution of the ADS crypto challenge that
  allows Samba to correctly handle a 128 bit session key in all of the
  netr_ServerAuthenticateX() varients. A huge thanks to Luke Howard
  from PADL for solving this one!

- restructured the server side rpc authentication to allow for other
  than NTLMSSP sign and seal. This commit just adds the structure, the
  next commit will add schannel server side support.

- added 128 bit session key support to our client side code, and
  testing against w2k3 with smbtorture. Works well.

21e6b1531b r464: a big improvement to the API for writing server-side RPC
servers. Previously the server pipe code needed to return the RPC
level status (nearly always "OK") and separately set the function call
return using r->out.result. All the programmers writing servers
(metze, jelmer and me) were often getting this wrong, by doing things
like "return NT_STATUS_NO_MEMORY" which was really quite meaningless
as there is no code like that at the dcerpc level.

I have now modified pidl to generate the necessary boilerplate so that
just returning the status you want from the function will work. So for
a NTSTATUS function you return NT_STATUS_XXX and from a WERROR
function you return WERR_XXX. If you really want to generate a DCERPC
level fault rather than just a return value in your function then you
should use the DCESRV_FAULT() macro which will correctly generate a
fault for you.

As a side effect, this also adds automatic type checking of all of our
server side rpc functions, which was impossible with the old API. When
I changed the API I found and fixed quite a few functions with the
wrong type information, so this is definately useful.

I have also changed the server side template generation to generate a
DCERPC "operation range error" by default when you have not yet filled
in a server side function. This allows us to correctly implement
functions in any order in our rpc pipe servers and give the client the
right information about the fault.

4d39861f99 avoid a copy of the data being input to the dcerpc server in the most
common case of there being no pending partial data and a full dcerpc
packet being received.

We should use this same model for the smb server. It gives us
efficient memory usage while allowing for completely async socket
operations.

7e6cf43756 This patch adds a better dcerpc server infastructure.
1.) We now register endpoint servers add startup via register_backend()
    and later use the smb.conf 'dcerpc endpoint servers' parameter to setup the dcesrv_context

2.) each endpoint server can register at context creation time as much interfaces as it wants
    (multiple interfaces on one endpoint are supported!)
    (NOTE:  there's a difference between 'endpoint server' and 'endpoint'!
	    for details look at rpc_server/dcesrv_server.h)

3.) one endpoint can have a security descriptor registered to it self
    this will be checked in the future when a client wants to connect
    to an smb pipe endpoint.

4.) we now have a 'remote' endpoint server, which works like the ntvfs_cifs module
    it takes this options in the [globals] section:

    dcerpc remote:interfaces = srvsvc, winreg, w32time, epmapper
    dcerpc remote:binding = ...
    dcerpc remote:user = ...
    dcerpc remote:password = ...

5.) we currently have tree endpoint servers: epmapper, rpcecho and remote

    the default for the 'dcerpc endpiont servers = epmapper, rpcecho'

    for testing you can also do
    dcerpc endpoint servers = rpcecho, remote, epmapper
    dcerpc remote:interfaces = srvsvc, samr, netlogon

6,) please notice the the epmapper now only returns NO_ENTRIES
    (but I think we'll find a solution for this too:-)

7.) also there're some other stuff left, but step by step :-)

This patch also includes updates for the
register_subsystem() , ntvfs_init(), and some other funtions
to check for duplicate subsystem registration

6f12e4ace1 it turns out that a wire policy handle isn't a blob either, its a
uint32 followed by a GUID. I needed to fix this to support running in
mixed-mode rpc (where smbtorture is bigendian and w2k3 is
little-endian). Otherwise when you send back a policy handle the
server doesn't recognise it.

24c22aef90 a fairly large commit!
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.

This required quite a bit of new infrastructure:

  * a generic way of handling dcerpc policy handles in the rpc server

  * added type checked varients of talloc. These are much less error
    prone. I'd like to move to using these for nearly all uses of
    talloc.

  * added more dcerpc fault handling code, and translation from
    NTSTATUS to a dcerpc fault code

  * added data_blob_talloc_zero() for allocating an initially zero
    blob

  * added a endpoint enumeration hook in the dcerpc endpoint server
