[PATCH v3 0/6] MR8326: ntdll: Implement RtlActivateActivationContextUnsafeFast().
For React Native. -- v3: kernel32/tests: Add tests for RtlActivateActivationContextUnsafe() and RtlDeactivateActivationContextUnsafeFast(). ntdll: Implement RtlDeactivateActivationContextUnsafeFast(). ntdll: Implement RtlActivateActivationContextUnsafeFast(). ntdll: Set and check 0x8 flag for activation context stack frames. kernel32/tests: Add tests for normal activation context stack frame flags. ntdll: Use explicit ACTIVATION_CONTEXT type instead of HANDLE. https://gitlab.winehq.org/wine/wine/-/merge_requests/8326

From: Zhiyi Zhang <zzhang(a)codeweavers.com> Prepare for RtlActivateActivationContextUnsafeFast(), which adds frames with flags 0x20. Normal frame flags are 0x28. So 0x8 is most likely to note that it's callee-allocated and needs to be freed in RtlFreeActivationContextStack(). Whereas missing 0x8 probably means a frame is caller-allocated. --- dlls/kernel32/tests/actctx.c | 3 --- dlls/ntdll/actctx.c | 5 +++-- dlls/ntdll/ntdll_misc.h | 3 +++ 3 files changed, 6 insertions(+), 5 deletions(-) diff --git a/dlls/kernel32/tests/actctx.c b/dlls/kernel32/tests/actctx.c index 71b1b5721fb..050b39516d9 100644 --- a/dlls/kernel32/tests/actctx.c +++ b/dlls/kernel32/tests/actctx.c @@ -2236,7 +2236,6 @@ static void test_actctx(void) frame = NtCurrentTeb()->ActivationContextStackPointer->ActiveFrame; ok(!frame->Previous, "Got unexpected Previous.\n"); ok(frame->ActivationContext == handle, "Got unexpected ActivationContext.\n"); - todo_wine ok(frame->Flags & NTDLL_ACTCTX_STACK_FRAME_HEAP_ALLOCATED, "Got unexpected Flags %#lx.\n", frame->Flags); b = DeactivateActCtx(0, cookie); @@ -2251,7 +2250,6 @@ static void test_actctx(void) frame = NtCurrentTeb()->ActivationContextStackPointer->ActiveFrame; ok(!frame->Previous, "Got unexpected Previous.\n"); ok(frame->ActivationContext == handle, "Got unexpected ActivationContext.\n"); - todo_wine ok(frame->Flags & NTDLL_ACTCTX_STACK_FRAME_HEAP_ALLOCATED, "Got unexpected Flags %#lx.\n", frame->Flags); b = DeactivateActCtx(0, cookie); @@ -2266,7 +2264,6 @@ static void test_actctx(void) frame = NtCurrentTeb()->ActivationContextStackPointer->ActiveFrame; ok(!frame->Previous, "Got unexpected Previous.\n"); ok(frame->ActivationContext == handle, "Got unexpected ActivationContext.\n"); - todo_wine ok(frame->Flags & NTDLL_ACTCTX_STACK_FRAME_HEAP_ALLOCATED, "Got unexpected Flags %#lx.\n", frame->Flags); b = DeactivateActCtx(0, cookie); diff --git a/dlls/ntdll/actctx.c b/dlls/ntdll/actctx.c index 7c8a4e0e1a9..d4dba2369e3 100644 --- a/dlls/ntdll/actctx.c +++ b/dlls/ntdll/actctx.c @@ -5443,7 +5443,7 @@ NTSTATUS WINAPI RtlActivateActivationContextEx( ULONG flags, TEB *teb, ACTIVATIO frame = RtlAllocateHeap( GetProcessHeap(), HEAP_GENERATE_EXCEPTIONS, sizeof(*frame) ); frame->Previous = actctx_stack->ActiveFrame; frame->ActivationContext = actctx; - frame->Flags = 0; + frame->Flags = NTDLL_ACTCTX_STACK_FRAME_HEAP_ALLOCATED; actctx_stack->ActiveFrame = frame; RtlAddRefActivationContext( actctx ); @@ -5508,7 +5508,8 @@ void WINAPI RtlFreeActivationContextStack( ACTIVATION_CONTEXT_STACK *actctx_stac { RTL_ACTIVATION_CONTEXT_STACK_FRAME *prev = frame->Previous; RtlReleaseActivationContext( frame->ActivationContext ); - RtlFreeHeap( GetProcessHeap(), 0, frame ); + if (frame->Flags & NTDLL_ACTCTX_STACK_FRAME_HEAP_ALLOCATED) + RtlFreeHeap( GetProcessHeap(), 0, frame ); frame = prev; } actctx_stack->ActiveFrame = NULL; diff --git a/dlls/ntdll/ntdll_misc.h b/dlls/ntdll/ntdll_misc.h index f82edef6b65..e0760afdc2a 100644 --- a/dlls/ntdll/ntdll_misc.h +++ b/dlls/ntdll/ntdll_misc.h @@ -35,6 +35,9 @@ #define NTDLL_TLS_ERRNO 16 /* TLS slot for _errno() */ +/* undocumented */ +#define NTDLL_ACTCTX_STACK_FRAME_HEAP_ALLOCATED 0x8 /* RTL_ACTIVATION_CONTEXT_STACK_FRAME.Flags */ + #ifdef __i386__ static const USHORT current_machine = IMAGE_FILE_MACHINE_I386; #elif defined(__x86_64__) -- GitLab https://gitlab.winehq.org/wine/wine/-/merge_requests/8326
