d09abeb686 r1004: continue tridge's work on dcerpc server auth/crypto code
I made it much more generic, and we should be able to add a
module interface to this code, so that other DCERPC_AUTH types can be added
via modules...

729b2f41c9 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.

cb070b9084 r623: setUserInfo level 24 (password set) now works in the SAMR server. This includes all
of the password complexity, password history and other password restrictions.

a4df5c7cf8 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.

6fbbfc4462 r374: allow for a policy_handle fetch using a handle type of
DCESRV_HANDLE_ANY. This is needed for operations like samr_Close()
that take any handle type.

917e45dafd 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

9b1c76a8e9 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.

6ee0935afe ntlmssp over rpc over tcp now fully works
I needed to hack the ntlmssp code a little, as the auth code in samba4
is out of date relative to the samba3 auth code. I need to do a merge :)

74041b6a0a fixed a bug handling multiple PDUs being read from a socket at one
time in the rpc server.

started on the framework for the dcerpc authentication server code

593bc29bbe completed the linkage between the endpoint mapper and the dcerpc
server endpoints. We can now successfully setup listening endpoints on
high ports, then use our endpoint mapper redirect incoming clients to
the right port.

also greatly cleanup the rpc over tcp session handling.

partial packets on both input and output

9fb0f03693 dcerpc over tcp in the samba4 server now works to some extent. It
needs quite a bit more work to get it finished. The biggest missing
feature is the lack of NTLMSSP which is needed for basic
authentication over tcp

097e7ca99d rpcdump.exe now works fine against a Samba4 server
for some reason the epm_Lookup replies can't be parsed by ethereal,
although w2k parses then fine as does the Samba4 NDR code.
-
Andrew Tridgell
3f85f9b782 added a basic dcerpc endpoint mapper to Samba4. Currently only
implements the epm_Lookup() call, I'll add the other important calls
soon. I was rather pleased to find that epm_Lookup() worked first
time, which is particularly surprising given its complexity.

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
    operations

4dac951718 we now support pdu fragmentation on both input and output in the rpc
server code
-
Andrew Tridgell
46e0a35819 * the RPC-ECHO pipe now works in smbd, as long as the data sizes
don't cause fragmented pdus (I'll add fragments shortly)

 * change data_blob_talloc() to not zero memory when the 2nd argument
   is NULL. The zeroing just masks bugs, and can't even allow a DOS
   attack

 * modified pidl to ensure that [ref] arguments to the out side of
   functions are allocated when parsing the in side. This allows rpc
   backends to assume that [ref] variables are all setup. Doesn't work
   correctly for [ref] arrays yet

 * changed DLIST_ADD_END() to take the type instead of a tmp
   variable. This means you don't need to declare a silly tmp variable in
   the caller
