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 metze (hmmm, my first large commit...I hope it works as supposed :-) (This used to be commit 917e45dafd5be4c2cd90ff425b8d6f8403122349)
