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.

a dcesrv module and also use the autogenerated boilerplate
you can just use:
#define DCESRV_INTERFACE_<UPPERCASE_INTERFACE_NAME>_BIND <interface_name>_bind
#define DCESRV_INTERFACE_<UPPERCASE_INTERFACE_NAME>_UNBIND <interface_name>_unbind
the prototype for the functions are the same as in
struct dcesrv_interface {
...
/* this function is called when the client binds to this interface */
NTSTATUS (*bind)(struct dcesrv_call_state *, const struct dcesrv_interface *);
/* this function is called when the client disconnects the endpoint */
void (*unbind)(struct dcesrv_connection *, const struct dcesrv_interface *);
...
};
e.g.
#define DCESRV_INTERFACE_WINREG_BIND winreg_bind
#define DCESRV_INTERFACE_WINREG_UNBIND winreg_unbind

- implement the interface_by_name() and interface_by_uuid() hooks
for the autogenerated dcerpc server boilerplates.

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

when starting a pipe. Thanks to metze for a script that gave the idea.
do something like this to use it:
pidl.pl --parse --template librpc/idl/XXX.idl > rpc_server/XXX/rpc_XXX.c
then fill in the functions in rpc_XXX.c

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