Rob Shearman : rpcrt4: The initialisation of [out] variables in the stubless code must be after the unmarshaling of [in] and [in, out] variables has been completed.
Module: wine Branch: master Commit: ed5b296289a991c00820f9b0a32e47a6aa3eb145 URL: http://source.winehq.org/git/wine.git/?a=commit;h=ed5b296289a991c00820f9b0a3... Author: Rob Shearman <rob(a)codeweavers.com> Date: Mon Jan 14 11:56:13 2008 +0000 rpcrt4: The initialisation of [out] variables in the stubless code must be after the unmarshaling of [in] and [in, out] variables has been completed. This is because the size of an [out] variable could depend on a conformance value stored in an unmarshalled [in] or [in,out] variable. --- dlls/rpcrt4/ndr_stubless.c | 63 +++++++++++++++++++++++++------------------- 1 files changed, 36 insertions(+), 27 deletions(-) diff --git a/dlls/rpcrt4/ndr_stubless.c b/dlls/rpcrt4/ndr_stubless.c index bc40641..8a99286 100644 --- a/dlls/rpcrt4/ndr_stubless.c +++ b/dlls/rpcrt4/ndr_stubless.c @@ -114,11 +114,12 @@ static inline unsigned long call_memory_sizer(PMIDL_STUB_MESSAGE pStubMsg, PFORM } #define STUBLESS_UNMARSHAL 1 -#define STUBLESS_CALLSERVER 2 -#define STUBLESS_CALCSIZE 3 -#define STUBLESS_GETBUFFER 4 -#define STUBLESS_MARSHAL 5 -#define STUBLESS_FREE 6 +#define STUBLESS_INITOUT 2 +#define STUBLESS_CALLSERVER 3 +#define STUBLESS_CALCSIZE 4 +#define STUBLESS_GETBUFFER 5 +#define STUBLESS_MARSHAL 6 +#define STUBLESS_FREE 7 void WINAPI NdrRpcSmSetClientToOsf(PMIDL_STUB_MESSAGE pMessage) { @@ -855,6 +856,7 @@ static DWORD calc_arg_size(MIDL_STUB_MESSAGE *pStubMsg, PFORMAT_STRING pFormat) pFormat = ComputeVariance(pStubMsg, NULL, pFormat, pStubMsg->MaxCount); size = ComplexStructSize(pStubMsg, pFormat); size *= pStubMsg->MaxCount; + break; default: FIXME("Unhandled type %02x\n", *pFormat); /* fallthrough */ @@ -915,6 +917,8 @@ static LONG_PTR *stub_do_args(MIDL_STUB_MESSAGE *pStubMsg, if (pParam->param_attributes.ServerAllocSize) HeapFree(GetProcessHeap(), 0, *(void **)pArg); break; + case STUBLESS_INITOUT: + break; case STUBLESS_UNMARSHAL: if (pParam->param_attributes.ServerAllocSize) *(void **)pArg = HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, @@ -988,7 +992,21 @@ static LONG_PTR *stub_do_args(MIDL_STUB_MESSAGE *pStubMsg, if (pParam->param_attributes.ServerAllocSize) HeapFree(GetProcessHeap(), 0, *(void **)pArg); - /* FIXME: call call_freer here for IN types with MustFree set */ + break; + case STUBLESS_INITOUT: + if (!pParam->param_attributes.IsIn && + pParam->param_attributes.IsOut && + !pParam->param_attributes.ServerAllocSize && + !pParam->param_attributes.IsByValue) + { + DWORD size = calc_arg_size(pStubMsg, pTypeFormat); + + if(size) + { + *(void **)pArg = NdrAllocate(pStubMsg, size); + memset(*(void **)pArg, 0, size); + } + } break; case STUBLESS_UNMARSHAL: if (pParam->param_attributes.ServerAllocSize) @@ -1002,18 +1020,6 @@ static LONG_PTR *stub_do_args(MIDL_STUB_MESSAGE *pStubMsg, else call_unmarshaller(pStubMsg, (unsigned char **)pArg, pTypeFormat, 0); } - else if (pParam->param_attributes.IsOut && - !pParam->param_attributes.ServerAllocSize && - !pParam->param_attributes.IsByValue) - { - DWORD size = calc_arg_size(pStubMsg, pTypeFormat); - - if(size) - { - *(void **)pArg = NdrAllocate(pStubMsg, size); - memset(*(void **)pArg, 0, size); - } - } break; case STUBLESS_CALCSIZE: if (pParam->param_attributes.IsOut || pParam->param_attributes.IsReturn) @@ -1127,14 +1133,9 @@ static LONG_PTR *stub_do_old_args(MIDL_STUB_MESSAGE *pStubMsg, call_freer(pStubMsg, *(unsigned char **)pArg, pTypeFormat); else if (pParam->param_direction == RPC_FC_OUT_PARAM) pStubMsg->pfnFree(*(void **)pArg); - break; - case STUBLESS_UNMARSHAL: - if (pParam->param_direction == RPC_FC_IN_OUT_PARAM || - pParam->param_direction == RPC_FC_IN_PARAM) - call_unmarshaller(pStubMsg, (unsigned char **)pArg, pTypeFormat, 0); - else if (pParam->param_direction == RPC_FC_RETURN_PARAM) - retval_ptr = (LONG_PTR *)pArg; - else if (pParam->param_direction == RPC_FC_OUT_PARAM) + break; + case STUBLESS_INITOUT: + if (pParam->param_direction == RPC_FC_OUT_PARAM) { DWORD size = calc_arg_size(pStubMsg, pTypeFormat); @@ -1145,6 +1146,13 @@ static LONG_PTR *stub_do_old_args(MIDL_STUB_MESSAGE *pStubMsg, } } break; + case STUBLESS_UNMARSHAL: + if (pParam->param_direction == RPC_FC_IN_OUT_PARAM || + pParam->param_direction == RPC_FC_IN_PARAM) + call_unmarshaller(pStubMsg, (unsigned char **)pArg, pTypeFormat, 0); + else if (pParam->param_direction == RPC_FC_RETURN_PARAM) + retval_ptr = (LONG_PTR *)pArg; + break; case STUBLESS_CALCSIZE: if (pParam->param_direction == RPC_FC_OUT_PARAM || pParam->param_direction == RPC_FC_IN_OUT_PARAM || @@ -1406,9 +1414,10 @@ LONG WINAPI NdrStubCall2( stubMsg.Buffer = stubMsg.BufferStart; } break; - case STUBLESS_MARSHAL: case STUBLESS_UNMARSHAL: + case STUBLESS_INITOUT: case STUBLESS_CALCSIZE: + case STUBLESS_MARSHAL: case STUBLESS_FREE: if (bV2Format) retval_ptr = stub_do_args(&stubMsg, &pFormat[parameter_start_offset],
