These private functions are needed to set up two different kinds of system's anonymous logon tokens: one that includes everyone in the group and the other that doesn't. These functions are needed as next step closer to the
implementation of NtImpersonateAnonymousToken system call.
for manually reported devices, as it is required by the newdev.dll
for installing drivers from INF files
CORE-17212 CORE-17398
Co-authored-by: Stanislav Motylkov <x86corez@gmail.com>
This control class is triggered when a driver is being installed for a
non-critical device. The driver info should already be in the registry
so we just need to push the device through the state graph
Meanwhile, combine the code for similar control classes into
PiControlSyncDeviceAction routine
CORE-17463 CORE-17490
In Windows Server 2003 the lock is initialised on a per-token basis, that is, the lock resource is created in SepDuplicateToken() and SepCreateToken() functions. This ensures that the lock initialisation is done locally for the specific token thus avoiding the need of a global lock.
Do not ditch the pages as soon as the section are unmapped
Improve MmBalancer "algorithm" (or whatever you call that)
Various needed fixes to get this going.
Previously, when creating a file section, Mm requested Cc to cache the file, then Cc would request pages from Mm, then Mm would request them back to serve its file-mapping role
Now, Mm does it all by itself. If file cahcing is requested by the FS driver, then Cc creates a file mapping and uses that to serve its purpose.
This is a rewrite of Cc
During the boot process, it makes possible to initalize the driver's
devices right after the driver is loaded. Moreover, this way one can be
sure that all critical devices are initialized before the
IopMarkBootPartition call (because we explicitly call the driver's
AddDevice routine now, after each driver is loaded)
CORE-7826
- Use DeviceNode->State field and its values, instead of
DeviceNode->Flags for tracking current node state
- Change DNF_* flags to the ones compatible with Windows XP+
- Simplify state changes for device nodes and encapsulate all the logic
inside the PiDevNodeStateMachine routine. This makes the ground for
future improvements in the device removal sequence and
resource management
- Now values inside DeviceNode->State and ->Flags are compatible with
the windbg !devnode macro and can be tracked using it
- BUGFIX: fixed cases where IRP_MN_START_DEVICE or
IRP_MN_QUERY_DEVICE_RELATIONS may be sent to a device after a
IRP_MN_REMOVE_DEVICE
CORE-7826
- Move the driver's name obtaining logic into the IopGetDriverNames
function
- Create a new PiCallDriverAddDevice instead of PipCallDriverAddDevice
and move it to pnpmgr/devaction.c file. Move around all its internal
helpers too
- Support a proper Windows-compatible driver loading order for a PDO
(lower filters, main service, upper filters, etc.)
- Set a correct Problem for the DeviceNode, in case of an error during
driver loading
- Check the Start Type for all drivers before loading
- Do not try to load drivers during the early boot stage when there is
no disk subsystem initialized
- Do not hold the IopDriverLoadResource while trying to reference a
driver object (but still acquire it when we actually need to load a
driver)
- Change IopLoadDriver and IopInitializeDriverModule to use registry
handle instead of a service name string and/or full registry path
- Do not try to reference a driver object inside IopLoadDriver. It's
supposed to be done before the function call
- Split IopLoadUnloadDriver into IopLoadDriver and calling DriverUnload
- Schedule the worker for (un)loading driver in a separate routine
(IopDoLoadUnloadDriver) this allows IopLoadDriver to be called
separately (if we are sure that we're in the system process)
- Remove IopCreateDriver and put its code into IoCreateDriver and
IopInitializeDriverModule. It's hard to extract a meaningful common
part from it
- Refactor IopInitializeDriverModule. Extend and put the DriverName
generation logic into it. Now this function frees the ModuleObject in
case of failure and returns STATUS_FAILED_DRIVER_ENTRY in case of
DriverInit failure (will be used later)
- Convert PARTITION_TABLE_OFFSET to the number of bytes instead of
(number of bytes) / 2. This avoids many confusing casts
- Use a cache aligned buffer for MBR
- BUGFIX: do not call IoGetRelatedTargetDevice while guarded mutex is acquired
(the function issues an APC, but they are disabled inside a critical section)
- BUGFIX: only the beginning of a structure for GUID_PNP_CUSTOM_NOTIFICATION was copied and queued.
Just pass it as-is to a subscriber, without copying
- Don't convert event GUID to string, store and compare GUID struct itself
- Split IopNotifyPlugPlayNotification into 3 functions for each type of notification
(less stack usage and for future changes)
- Move initialization code for notifications into a separate routine
- Use separate lists and locks for every type of notification
- Put "TargetDeviceChange" notifications into their place inside DEVICE_NODE
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore
Introduce the PiPerformSyncDeviceAction routine for queuing
synchronous device actions
Change all kernel code to use PiPerformSyncDeviceAction and
PiQueueDeviceAction for device enumeration
CORE-10456
If SEH is used in a C trap handler, the exception frame will be
registered before the call to KiEnterTrap, which means we save
the wrong trap handler. We'll therefore also restore this wrong
frame for the excepting code, resulting in a stale SEH chain.
We avoid this problem by saving the handler in the assembly
trap entry code instead of from C. While SEH in a C trap handler
should now theoretically be safe, we still forbid it through
asserts in the C KiEnterTrap variants to make any potential
future problems more obvious. Should this functionality be
needed at some point and deemed safe, these asserts can then be
removed.
- Improve the device action worker to support more than just a single action
- Move the action queue code from IoInvalidateDeviceRelations to a new function IopQueueDeviceAction.
Our legacy KD module is slowly being phased out for the more recent KD64
Kernel Debugger that supports WinDbg, but at the same time we must retain
support for GCC debugging and the KDBG interface.
For the time being few #ifdef _WINKD_ have been introduced in KD64 so that
some of its code/data does not completely get shared yet with the legacy KD,
until the latter becomes phased out.
KD Modifications:
=================
- Remove the implementation of NtQueryDebugFilterState() /
NtSetDebugFilterState() that now comes entirely from KD64.
- Remove KD variables that are now shared with KD64.
- Share common code with KD64: KdpMoveMemory(), KdpZeroMemory(),
KdpCopyMemoryChunks(), KdpPrint(), KdpPrompt().
- KDBG: Remove the duplicated KdpCopyMemoryChunks() function.
- In KdpServiceDispatcher() and KdpEnterDebuggerException(), call the
KdpPrint() worker function that correctly probes and captures its arguments.
- Temporarily stub out KdEnterDebugger() and KdExitDebugger() that is used
by the shared code, until KD is removed and only the KD64 version of these
functions remain.
- Re-implement the KD/KDBG KdpPrompt() function using a custom KdpPromptString()
helper compatible with KD64, that is called by the KD64 implementation of
KdpPrompt(). This KdpPromptString() helper now issues the prompt on all
the KD loggers: e.g. if you use both at the same time COM-port and SCREEN
debugging, the prompt will appear on both. Before that the prompt was always
being displayed on COM port even if e.g. a SCREEN-only debug session was used...
- ppc_irq.c: Fix the prototype of KdpServiceDispatcher().
KD64 Fixes:
===========
- Initialize the MaximumLength member of the counted STRING variables
before using them elsewhere.
- Get rid of alloca() within SEH block in KdpPrint() (addendum to 7b95fcf9).
- Add the ROS-specific handy dump commands in KdSystemDebugControl().
- KD64: Update the list of supported Debug Filter Masks (KdComponentTable)
with the more up-to-date one from KDBG, that includes some components
that have been added in Vista+, but some of which we also use in ReactOS.
- NtQueryDebugFilterState(), NtSetDebugFilterState() and KdpPrint():
Add the Vista+ behaviour or falling back to the DEFAULT component ID
settings for unknown Components (compiled in only wheen NTDDI_VERSION >= NTDDI_VISTA).
+ Remove redundant comments and update these functions with SAL2 annotations.
- KDBG: Add extra documentation for the debug filter components list.
- CONFIG: Load all the supported Debug Filter Masks settings from the
registry.
- Introduce KdpScreenAcquire() / KdpScreenRelease() helpers that allow
to correctly acquire or release the screen when using INBV for
"Screen-Mode" debugging.
- Introduce KdpAcquireLock() / KdpReleaseLock() helpers so as to reduce
the copy-pasted code required when acquiring spin-locks in the KD debug
logger functions.
- Close the opened KdpLogFileHandle file in the KdpInitDebugLog() logger
in case we failed to create the logger writer thread.
Also use explicit kernel-mode handle when opening the log file.
- static-ify some local variables, remove few hardcoded values, and
minor formatting.
- Correctly define the INIT_FUNCTION's.
The major change with this rewrite is the support for the mount
manager. Fstub will now assume that most of the devices are PnP
and that they are already registered to the mount manager.
It will thus ask the mount manager to assign the drive letter.
Fstub will keep assigning drive letters non mission critical devices
such as CDs, floppies and other removable devices.
See MountMgr:QueryPoints API test that will now return mount points :-).
* [NTOS:INBV] Move typedefs to the only single file where they are used.
* [NTOS:INBV] Refactor code & resources
Remove garbage
* [NTOS:INBV] Reduce fade time and remove wait for animation.
This allows setting the memory protection of the kernel's resource
section as will. MmMakeKernelResourceSectionWritable() is re-implemented
around this helper.
This allows getting rid of the ?? hack in the kernel but this doesn't
allow enabling LUID device maps as ReactOS can no longer open a
session with them enabled. So, we must remain with device maps at
root
CORE-16114
- Introduce the MmMakeKernelResourceSectionWritable() helper for
making the kernel resource memory section writable, and use it
in KeGetBugMessageText(). Indeed, this latter function patches
in place the bugcheck resource message to trim any trailing
newlines before displaying the message on screen.
See also https://github.com/osresearch/uxen/blob/83bad53/dm/introspection-win7.c#L286
that mentions it too.
This fixes bugcheck text display (e.g. the MANUALLY_INITIATED_CRASH one)
when using (at least) MSVC-built ReactOS, avoiding a Page-Fault
exception during the bugcheck.
- Cover KeGetBugMessageText() in SEH since we are accessing kernel
resources that could also be corrupted in bugcheck scenarii, and we
don't want to further bugcheck.
- Fix newline trimming loop.
- KiDoBugCheckCallbacks():
* Wrap the bugcheck CallbackRoutine call in SEH.
* Add a FIXME concerning the need of further memory validation of CurrentRecord.
- Add a FIXME concerning the need to run the bugcheck-reason callbacks
with the KbCallbackReserved1 reason, in KeBugCheckWithTf().
Mentioned in http://blog.ptsecurity.com/2012/06/customizing-blue-screen-of-death.html
- Un-hardcode the RPL_MASK value.
- s/KiUnexpectedInterrupt&Number/KiUnexpectedInterrupt&Vector/
- Use C-style comments in traphdlr.c as everywhere else in the file.
- Update the URLs for the MSDN "FPO" macro documentation.
It is now able to set the newly created device map to any
process and will default to current process if none is provided.
It also sets system device map if no process is specified.
It also deferences existing device map in the process if needed.
Finaly, it will make the directory object permanant.
- Always include kd64.h
- Change KdpPrompt() prototype to be compatible between KDBG and _WINDK_
- Rename KdComponentTable to KdpComponentTable to prevent a conflict
- Add some functions stubs and global variables
- Add and initialize a global power capabilities variable.
- Return the global power capabilities via NtPowerInformation.SystemPowerCapabilities.
- Report the presence of power button, sleep button and lid.
* The previous version was overcomplicated and broken and therefore disabled.
* The new version also enforces NX protection on x64.
* Now that protecting works, also protect the boot loaded images.
* [WIN32K] Fix handle calculation in DbgGdiHTIntegrityCheck
* [NOTEPAD] Fix MSVC warnings
* [PSDK] Simplify *PROC definitions in windef.h
* [VIDEOPRT] Don't try to use NtVdmControl on x64
* [FREELDR] Fix some macros
* [CRT] Make qsort 64 bit compatible
* [NTOS] Use #ifndef _WIN64 instead of #ifdef _M_IX86 around C_ASSERTs
* [FAST486] Fix 64 bit warnings and change DWORD to ULONG, so it can be used in kernel mode
* [APPHELP_APITEST] Fix 64 bit issue
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr
For now, this is just a split between scan and flush that
were both done during lazy scan previously.
Lazy scan shouldn't perform any write operation, but only
queue a write behind operation.
Our implementation is far from the original, as it seems
our lazy scan should queue a write behind operation per
shared cache map. Right now, we only perform global
operation.
- Rework CmpSetSystemValues() and remove its 1st-stage text-mode setup hack, since a real registry hive will be used for 1st-stage either.
- Lock, then unlock the registry in NtInitializeRegistry when initializing the hives & flusher.
- Call CmpInitializeHiveList() (i.e., initialize the other hives like \Software, \User, \.Default) only when we are not in setup-mode.
