- The original code was just incrementing the reference counts (RefCounts)
of the device objects or the device/file handles, without decrementing
them when closing the handles. This is now fixed.
Notice the following:
* When opening a file on a device (disk), the device's (and its
handle's) RefCount is incremented, and the file handle's RefCount
is incremented as well.
* When closing a file, the file handle's RefCount is decremented
(and the file closed if the RefCount reaches zero), and the file's
parent device handle is also closed, recursively.
This has the effect of decrementing the parent device handle's
RefCount, and the device's own RefCount is decremented as well.
IMPORTANT NOTE: The usefulness of handle-level RefCount is still
under question, and might be (consistently) removed in the future.
- Fix opening a device (disk) in direct access, when this device is
already opened. Indeed, we previously allowed direct access only if
the device was opened as such for the very first time (its RefCount
= 0 originally); no filesystem mounting was attempted as well.
Then for any later open-operations on this device (while keeping an
already-opened handle to it), filesystem access was assumed.
Thus, this problem would show up in two ways:
* Either the device is first opened for direct access, this succeeded
and no filesystem was mounted. Then, for any other open-operations,
the filesystem was NOT mounted, and opening files on it would fail.
Direct accesses would succeed but would create an unnecessary second
file handle.
* Or, the device is first opened for file-access: a filesystem was
mounted and file opening would succeed. Any other file opening
operation would succeed as well (if the file exists). But, a direct
access open-operation would fail, because now any open-operations on
the device would be assumed to be a file opening.
This is now correctly fixed. If direct-open is requested, just do it.
If this is a file opening, we open the device, then try to mount a
filesystem on it (if not already done), then we try to open the file.
If file opening fails, derereference the device.
- Pass the file path to the filesystem-specific Open() functions without
truncating the leading path separator, if any. This has to be handled
by the filesystem routines themselves.
This prevents MSVC from reordering the exports in a way that doesn't match our spec file. Also improve the algorithm to apply ordinals, by starting with the first specified ordinal, possibly reserving ordinals for anything declared without an ordinal before.
PathIsExeW is used and will exclude exe, com, pif, cmd, bat, scf and scr. The previous #6122 PR added support for the FTA_Exclude flag and that will exclude .lnk files.

Addendum to commit baa47fa5e.
Similarly to what was originally done, have KdbpCliInterpretInitFile()
parse the KDBinit file by breaking back into the debugger.
But contrary to before, replace the deprecated call to KdbEnter() by
a standard DbgBreakPointWithStatus(DBG_STATUS_CONTROL_C) . This allows
KdbEnterDebuggerException() to do the KdbpCliInterpretInitFile() call.
Additional fixes and improvements:
- Run KdbpCliInterpretInitFile() in full KDBG environment (interrupts
disabled, modified IRQL, own stack), like the usual interactive loop.
- The KDBinit data buffer must be in non-paged pool.
- Demote the "Could not open KDBinit" error to a DPRINT, so that it
doesn't pollute the debug log when the KDBG init function is called
early (before the storage stack is initialized), or if the file
doesn't exist -- since this is an optional feature.
- Move the printing pager state reset code (setting the number of
printed rows and columns to zero, and the output aborted flag)
to KdbpDoCommand(). This allows to keep the original behaviour,
while also inheriting it whenever KdbpDoCommand() is invoked
elsewhere (for example, from KdbpCliInterpretInitFile()).
- Use KdbPuts/Printf() instead of KdbpPrint() for the entry banners,
so that they aren't subject to the current printing pager state.
Do the same for the "command unknown" error in KdbpDoCommand().
- Add a "Type 'help' for a list of commands" banner, for the users.
- Replace the do-while-loop with a simple while-loop.
- Support loading protocols like XP
- Support most of the relevant EditFlags
- Support reading/writing the AlwaysShowExt and BrowserFlags properties
- Loads the list much faster with optimized code and delaying the large icon and description string
- Reduce the number of magic buffer sizes by replacing them with defines that are in the ballpark of being correct
- Implemented column sorting
- Removed custom icon extraction code
- Removed IDS_FILE_EXT_TYPE string because it must be the same as IDS_ANY_FILE
- Don't touch verb keys that are not edited to retain the original REG type
- Don't clobber unchanged %1 icon location when editing a type
CORE-19756
Those haven't been groomed anymore for more than 10 years. We had many thousands of
different freeldr builds with different behavior and bugs each, but nobody ever
did have the slightest motivation to update those hardcoded
FREELOADER_MAJOR_VERSION, FREELOADER_MINOR_VERSION, FREELOADER_PATCH_VERSION
from ver.h. And that is logical, because touching other modules will change the behavior
of freeldr as well, so it is absolutely impossible to groom anything like that correctly.
Instead we should simply do what we started to do in PR7383, which will at least give
some information (the actual sources it was built from) instead of some misleading voodoo-version.
This might slightly shrink the size of freeldr as well, but I was too lazy to measure by how much.
This function combines those that write a message to and read
a message from the specified pipe into a single operation.
Its usage helps in simplifying the code further.
In addition:
- Acquire ControlServiceCriticalSection just before doing the pipe
operations, and release it just after.
- SAL2-annotate ScmControlService().
- Re-order the ScmControlService() parameters in a more natural way
(image comm pipe, service name, control code; then: arguments for
the control command).
- Improve some DPRINTs.
Tweaks all AUTOCHECKBOXes in desk.cpl
no functional change intended, it seems to work well when testing it locally
Makes the rcs shorter
it also makes the binaries a few bytes smaller:
GCC8.4.0dbg RosBEWin2.2.2 DESK.CPL shrinks 650.240 bytes -> 647.168 bytes
it prettifies also the display in reshacker
Previously FsRtlNotifyVolumeEvent would pass a pointer to a TARGET_DEVICE_CUSTOM_NOTIFICATION structure on the stack to IoReportTargetDeviceChangeAsynchronous, which would store a pointer to it in a work-item and process that after the stack object was already out of scope. This broke x64 boot. Started happening after recent fixes to IoReportTargetDeviceChangeAsynchronous.

Fix the case when GetDriveTypeW would return DRIVE_NO_ROOT_DIR when it
got a volume GUID name and had to access an unformatted volume.
Fixes Rufus not being able to find an unformatted volume after writting new MBR.
QueryDeviceInformation returns more reliable volume length and works
with unformatted volumes. It will return volume length only on ROS and Vista+ however,
so also keep the GetFreeDiskSpaceExW as a fallback for XP/2003.
