Tests show that NdrPointerFree (and hence NdrFree) don't check whether the memory was allocated with NdrAllocate before freeing it. This makes sense as servers don't need to use NdrAllocate to allocate memory being returned and so this commit caused that memory to be leaked. NdrAllocate hasn't been changed as the tests show it is correct and it appears that the memory list is used to implement the RpcSs memory model. --- dlls/rpcrt4/ndr_marshall.c | 25 +------------------------ dlls/rpcrt4/tests/ndr_marshall.c | 6 ------ 2 files changed, 1 insertions(+), 30 deletions(-) diff --git a/dlls/rpcrt4/ndr_marshall.c b/dlls/rpcrt4/ndr_marshall.c index bd5c81d..5e77d18 100644 --- a/dlls/rpcrt4/ndr_marshall.c +++ b/dlls/rpcrt4/ndr_marshall.c @@ -373,32 +373,9 @@ void * WINAPI NdrAllocate(MIDL_STUB_MESSAGE *pStubMsg, size_t len) static void WINAPI NdrFree(MIDL_STUB_MESSAGE *pStubMsg, unsigned char *Pointer) { - NDR_MEMORY_LIST *mem_list, *prev_mem_list; - TRACE("(%p, %p)\n", pStubMsg, Pointer); - for (prev_mem_list = NULL, mem_list = pStubMsg->pMemoryList; - mem_list; - prev_mem_list = mem_list, mem_list = mem_list->next) - { - const unsigned char *base_pointer = (unsigned char *)mem_list - mem_list->size; - if (base_pointer == Pointer) - { - if (mem_list->magic != MEML_MAGIC) - { - ERR("memory linked list corrupted, magic changed to 0x%08x\n", mem_list->magic); - break; - } - - /* fixup next pointers */ - if (prev_mem_list) - prev_mem_list->next = mem_list->next; - else - pStubMsg->pMemoryList = mem_list->next; - pStubMsg->pfnFree(Pointer); - break; - } - } + pStubMsg->pfnFree(Pointer); } static inline BOOL IsConformanceOrVariancePresent(PFORMAT_STRING pFormat) diff --git a/dlls/rpcrt4/tests/ndr_marshall.c b/dlls/rpcrt4/tests/ndr_marshall.c index 391f277..ba5243b 100644 --- a/dlls/rpcrt4/tests/ndr_marshall.c +++ b/dlls/rpcrt4/tests/ndr_marshall.c @@ -1193,17 +1193,13 @@ todo_wine { my_free_called = 0; StubMsg.Buffer = StubMsg.BufferStart; NdrPointerFree( &StubMsg, mem, fmtstr_conf_str ); -todo_wine { ok(my_free_called == 1, "free called %d\n", my_free_called); -} mem = my_alloc(10); my_free_called = 0; StubMsg.Buffer = StubMsg.BufferStart; NdrPointerFree( &StubMsg, mem, fmtstr_conf_str ); -todo_wine { ok(my_free_called == 1, "free called %d\n", my_free_called); -} /* Server */ my_alloc_called = 0; @@ -1246,9 +1242,7 @@ todo_wine { my_free_called = 0; StubMsg.Buffer = StubMsg.BufferStart; NdrPointerFree( &StubMsg, mem, fmtstr_conf_str ); -todo_wine { ok(my_free_called == 1, "free called %d\n", my_free_called); -} HeapFree(GetProcessHeap(), 0, mem_orig); HeapFree(GetProcessHeap(), 0, StubMsg.RpcMsg->Buffer);
