From 2f253986df3e5cf5aca0bb2fcec2e23c0cab57d7 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 4 Dec 2018 19:59:29 -0500 Subject: kernel/svc: Correct behavior of svcResetSignal() While partially correct, this service call allows the retrieved event to be null, as it also uses the same handle to check if it was referring to a Process instance. The previous two changes put the necessary machinery in place to allow for this, so we can simply call those member functions here and be done with it. --- src/core/hle/kernel/svc.cpp | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) (limited to 'src/core') diff --git a/src/core/hle/kernel/svc.cpp b/src/core/hle/kernel/svc.cpp index e6c77f9db..84df2040e 100644 --- a/src/core/hle/kernel/svc.cpp +++ b/src/core/hle/kernel/svc.cpp @@ -1433,17 +1433,24 @@ static ResultCode CloseHandle(Handle handle) { return handle_table.Close(handle); } -/// Reset an event +/// Clears the signaled state of an event or process. static ResultCode ResetSignal(Handle handle) { LOG_DEBUG(Kernel_SVC, "called handle 0x{:08X}", handle); const auto& handle_table = Core::CurrentProcess()->GetHandleTable(); + auto event = handle_table.Get(handle); + if (event) { + return event->Reset(); + } - ASSERT(event != nullptr); + auto process = handle_table.Get(handle); + if (process) { + return process->ClearSignalState(); + } - event->Clear(); - return RESULT_SUCCESS; + LOG_ERROR(Kernel_SVC, "Invalid handle (0x{:08X})", handle); + return ERR_INVALID_HANDLE; } /// Creates a TransferMemory object -- cgit v1.2.3
