commit a43bfe2916814cb521dd2109f950adb0fdebb8f6 Author: Hermès Bélusca-Maïto <[email protected]> AuthorDate: Fri Aug 9 17:39:00 2024 +0200 Commit: Hermès Bélusca-Maïto <[email protected]> CommitDate: Sun Dec 15 22:12:22 2024 +0100 [NTOS:CM/IO/KE] Implement minimal support for CrashControl:AutoReboot The REG_DWORD value `AutoReboot` stored in the registry key `HKLM\SYSTEM\CurrentControlSet\Control\CrashControl` (used as a boolean value), controls whether to automatically reboot the operating system at the end of the crash dump, after a bugcheck. ReactOS doesn't currently implement crash dumps, so only the auto-reboot is done. (The reason of the apparent redundant `Reboot` variable in KeBugCheckWithTf() is because that variable would be updated on return by the not-yet-existing crash-dump helper routines called from there.) --- ntoskrnl/config/cmdata.c | 9 +++++++-- ntoskrnl/include/internal/io.h | 1 + ntoskrnl/io/iomgr/iomgr.c | 1 + ntoskrnl/ke/bug.c | 2 ++ 4 files changed, 11 insertions(+), 2 deletions(-) diff --git a/ntoskrnl/config/cmdata.c b/ntoskrnl/config/cmdata.c index 693c9ac7b26..4656fe85cdd 100644 --- a/ntoskrnl/config/cmdata.c +++ b/ntoskrnl/config/cmdata.c @@ -624,8 +624,6 @@ DATA_SEG("INITDATA") CM_SYSTEM_CONTROL_VECTOR CmControlVector[] = NULL, NULL }, - - { L"ProductOptions", L"ProductSuite", @@ -926,6 +924,13 @@ DATA_SEG("INITDATA") CM_SYSTEM_CONTROL_VECTOR CmControlVector[] = NULL, NULL }, + { + L"CrashControl", + L"AutoReboot", + &IopAutoReboot, + NULL, + NULL + }, { NULL, NULL, diff --git a/ntoskrnl/include/internal/io.h b/ntoskrnl/include/internal/io.h index 10dc76bc2ba..f78c05a14be 100644 --- a/ntoskrnl/include/internal/io.h +++ b/ntoskrnl/include/internal/io.h @@ -1453,6 +1453,7 @@ extern GENERIC_MAPPING IopFileMapping; extern POBJECT_TYPE _IoFileObjectType; extern HAL_DISPATCH _HalDispatchTable; extern LIST_ENTRY IopErrorLogListHead; +extern ULONG IopAutoReboot; extern ULONG IopNumTriageDumpDataBlocks; extern PVOID IopTriageDumpDataBlocks[64]; extern PIO_BUS_TYPE_GUID_LIST PnpBusTypeGuidList; diff --git a/ntoskrnl/io/iomgr/iomgr.c b/ntoskrnl/io/iomgr/iomgr.c index b982414e270..249d93b6cae 100644 --- a/ntoskrnl/io/iomgr/iomgr.c +++ b/ntoskrnl/io/iomgr/iomgr.c @@ -43,6 +43,7 @@ LARGE_INTEGER IoWriteTransferCount = {{0, 0}}; ULONG IoOtherOperationCount = 0; LARGE_INTEGER IoOtherTransferCount = {{0, 0}}; KSPIN_LOCK IoStatisticsLock = 0; +ULONG IopAutoReboot; ULONG IopNumTriageDumpDataBlocks; PVOID IopTriageDumpDataBlocks[64]; diff --git a/ntoskrnl/ke/bug.c b/ntoskrnl/ke/bug.c index 297de556fe4..7cb9c1c2e67 100644 --- a/ntoskrnl/ke/bug.c +++ b/ntoskrnl/ke/bug.c @@ -1134,6 +1134,8 @@ KeBugCheckWithTf(IN ULONG BugCheckCode, /* FIXME: Support Triage Dump */ /* FIXME: Write the crash dump */ + // TODO: The crash-dump helper must set the Reboot variable. + Reboot = !!IopAutoReboot; } else {
