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

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().
