- added server side support for schannel type 23. This allows WinXP to establish a schannel connection
to Samba4 as an ADS DC
- added client side support for schannel type 23, but disabled it as currently the client
code has now way of getting the fully qualified domain name (which is needed)
- report dcerpc faults in the server code in the log
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

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

(hmmm, my first large commit...I hope it works as supposed :-)
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
