a5eb6cad50 r2105: added a TestSleep() operation to the echo pipe and extended the
RPC-ECHO test to use it to test asynchronous rpc operations.

9a9244a1c6 r873: converted samba4 to use real 64 bit integers instead of
structures. This was suggested by metze recently.

I checked on the build farm and all the machines we have support 64
bit ints, and support the LL suffix for 64 bit constants. I suspect
some won't support strtoll() and related functions, so we will
probably need replacements for those.

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.

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

bd3dcfe582 added auto-generation of the server side boilerplate code for each
pipe.

The server side code gets generated as librpc/gen_ndr/ndr_NAME_s.c and
gets included in the pipe module

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.

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

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

30a996b682 after chatting with jeremy I decided to use a separate directory for
each rpc endpoint implementation, so we will have rpc_server/samr/
rpc_server/lsa/ etc.

this should encourage each pipe to be written in a more complete
manner, as it gives easy ways to split the pipe into multiple modules.
