For widl * to be wine's only IDL compiler, a fair bit of work remains to be done. * until then we have used some midl-generated stuff. (What?) * widl currently doesn't generate stub/proxy files required by wine's (O)RPC * capabilities -- nor does it make those lovely format strings :( * The MS MIDL compiler does some really esoteric stuff. Of course Ove has * started with the less esoteric stuff. There are also lots of nice * comments in there if you want to flex your bison and help build this monster. * * - RPC has a quite featureful error handling mechanism; basically none of this is * implemented right now. We also have deficiencies on the compiler side, where * wine's __TRY / __EXCEPT / __FINALLY macros are not even used for RpcTryExcept & co, * due to syntactic differences! (we can fix it with widl by using __TRY) * * - There are several different memory allocation schemes for MSRPC. * I don't even understand what they all are yet, much less have them * properly implemented. Surely we are supposed to be doing something with * the user-provided allocation/deallocation functions, but so far, * I don't think we are doing this... * * - MSRPC provides impersonation capabilities which currently are not possible * to implement in wine. At the very least we should implement the authorization * API's & gracefully ignore the irrelevant stuff (to an extent we already do). * * - Some transports are not yet implemented. The existing transport implementations * are incomplete and may be bug-infested. * * - The various transports that we do support ought to be supported in a more * object-oriented manner, as in DCE's RPC implementation, instead of cluttering * up the code with conditionals like we do now. * * - Data marshalling: So far, only the beginnings of a full implementation * exist in wine. NDR protocol itself is documented, but the MS API's to * convert data-types in memory into NDR are not. This is challenging work, * and has supposedly been "at the top of Greg's queue" for several months now. * * - ORPC is RPC for OLE; once we have a working RPC framework, we can * use it to implement out-of-process OLE client/server communications. * ATM there is maybe a disconnect between the marshalling in the OLE DLLs * and the marshalling going on here [TODO: well, is there or not?] * * - In-source API Documentation, at least for those functions which we have * implemented, but preferably for everything we can document, would be nice, * since some of this stuff is quite obscure. * * - Name services... [TODO: what about them] * * - Protocol Towers: Totally unimplemented.... I think. * * - Context Handle Rundown: whatever that is. * * - Nested RPC's: Totally unimplemented. * * - Statistics: we are supposed to be keeping various counters. we aren't. * * - Async RPC: Unimplemented. * * - XML/http RPC: Somewhere there's an XML fiend that wants to do this! Betcha * we could use these as a transport for RPC's across computers without a * permissions and/or licensing crisis. * * - The NT "ports" API, aka LPC. Greg claims this is on his radar. Might (or * might not) enable users to get some kind of meaningful result out of * NT-based native rpcrt4's. Commonly-used transport for self-to-self RPC's. * * - ...? More stuff I haven't thought of. If you think of more RPC todo's * drop me an e-mail or send a patch to the * wine-patches mailing list. */ #include "config.h" #include #include #include #include #include "windef.h" #include "winerror.h" #include "winbase.h" #include "winuser.h" #include "winnt.h" #include "winternl.h" #include "iptypes.h" #include "iphlpapi.h" #include "wine/unicode.h" #include "rpc.h" #include "ole2.h" #include "rpcndr.h" #include "rpcproxy.h" #include "rpc_binding.h" #include "rpcss_np_client.h" #include "wine/debug.h" WINE_DEFAULT_DEBUG_CHANNEL(rpc); static UUID uuid_nil; static HANDLE master_mutex; HANDLE RPCRT4_GetMasterMutex(void) { return master_mutex; } static CRITICAL_SECTION uuid_cs; static CRITICAL_SECTION_DEBUG critsect_debug = { 0, 0, &uuid_cs, { &critsect_debug.ProcessLocksList, &critsect_debug.ProcessLocksList }, 0, 0, { (DWORD_PTR)(__FILE__ ": uuid_cs") } }; static CRITICAL_SECTION uuid_cs = { &critsect_debug, -1, 0, 0, 0, 0 }; static CRITICAL_SECTION threaddata_cs; static CRITICAL_SECTION_DEBUG threaddata_cs_debug = { 0, 0, &threaddata_cs, { &threaddata_cs_debug.ProcessLocksList, &threaddata_cs_debug.ProcessLocksList }, 0, 0, { (DWORD_PTR)(__FILE__ ": threaddata_cs") } }; static CRITICAL_SECTION threaddata_cs = { &threaddata_cs_debug, -1, 0, 0, 0, 0 }; struct list threaddata_list = LIST_INIT(threaddata_list); struct threaddata { struct list entry; CRITICAL_SECTION cs; DWORD thread_id; RpcConnection *connection; }; /*********************************************************************** * DllMain * * PARAMS * hinstDLL [I] handle to the DLL's instance * fdwReason [I] * lpvReserved [I] reserved, must be NULL * * RETURNS * Success: TRUE * Failure: FALSE */ BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved) { struct threaddata *tdata; switch (fdwReason) { case DLL_PROCESS_ATTACH: master_mutex = CreateMutexA( NULL, FALSE, RPCSS_MASTER_MUTEX_NAME); if (!master_mutex) ERR("Failed to create master mutex\n"); break; case DLL_THREAD_DETACH: tdata = NtCurrentTeb()->ReservedForNtRpc; if (tdata) { EnterCriticalSection(&threaddata_cs); list_remove(&tdata->entry); LeaveCriticalSection(&threaddata_cs); DeleteCriticalSection(&tdata->cs); if (tdata->connection) ERR("tdata->connection should be NULL but is still set to %p\n", tdata); HeapFree(GetProcessHeap(), 0, tdata); } case DLL_PROCESS_DETACH: CloseHandle(master_mutex); master_mutex = NULL; break; } return TRUE; } /************************************************************************* * RpcStringFreeA [RPCRT4.@] * * Frees a character string allocated by the RPC run-time library. * * RETURNS * * S_OK if successful. */ RPC_STATUS WINAPI RpcStringFreeA(RPC_CSTR* String) { HeapFree( GetProcessHeap(), 0, *String); return RPC_S_OK; } /************************************************************************* * RpcStringFreeW [RPCRT4.@] * * Frees a character string allocated by the RPC run-time library. * * RETURNS * * S_OK if successful. */ RPC_STATUS WINAPI RpcStringFreeW(RPC_WSTR* String) { HeapFree( GetProcessHeap(), 0, *String); return RPC_S_OK; } /************************************************************************* * RpcRaiseException [RPCRT4.@] * * Raises an exception. */ void WINAPI RpcRaiseException(RPC_STATUS exception) { /* FIXME: translate exception?
