Instead of PlugPlayControlResetDevice, PlugPlayControlStartDevice should
be used for a newly installed device.
For usetup, add a device status check before starting attempt, so we're
not touching devices which are already started.

The AsciiChar of the ESCAPE key should be 0x1B instead of zero; however
this is not the case due to the hacked keyboard layout currently being
used. This will be fixed later ...
- Use NT values for uninitialized handle values.
- Cache the STD_INPUT_HANDLE.
- Free the console if GetConsoleScreenBufferInfo() fails in CONSOLE_Init().
- Use PnP storage class drivers
- Make partmgr an upper filter driver for Disk class
- Fill upper filters in txtsetup and usetup/devinst
- Add cdrom driver to the critical device database
CORE-6264
Add two hacks in UpdateDiskLayout() and WritePartitions() so that the
disk partition style is consistently set to a known value MBR, especially
when that disk was previously new and uninitialized (RAW).
A proper fix will be developed later when support for GPT is added.
so that they wrap the needed init steps for formatting/chkdsk'ing.
These helpers now accept a PPARTENTRY, together with the usual
formatting/chkdsk parameters. The helpers now determine the actual
NT path to use, and can perform the init steps on the partition
before performing the actual operation.
In particular, FormatPartition() is now made GPT-compliant. The
partition type retrieved by FileSystemToMBRPartitionType() is now
used as a hint for choosing FAT32 over FAT12/16, and only in the
case of a MBR partition that is *NOT* a recognized OEM partition,
it is used for updating the corresponding partition type. (OEM
partitions must retain their original type.)
The OEM partition types we (and NT) can recognize are specified
e.g. in the Microsoft Open-Specification [MS-DMRP] Appendix B
https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-dmrp/5f5043a3-9e6d-40cc-a05b-1a4a3617df32
Introduce an IsOEMPartition() macro to help checking for these types
(its name is based on the Is***Partition() macros from ntdddisk.h,
and from a dmdskmgr.dll export of similar name).
Instead of providing an MBR partition type to InferFileSystem(), make
it call IOCTL_DISK_GET_PARTITION_INFO(_EX) to determine whether the
partition pointed by the path/handle is MBR or GPT. Then, only if it's
MBR, we retrieve its partition type in order to "guess" an adequate file
system name, in case the latter was not recognized already via regular
ways (via GetFileSystemName() / NtQueryVolumeInformationFile()).
- Remove the GetFileSystemNameByHandle() and InferFileSystemByHandle()
functions. Instead, make the other GetFileSystemName*() and
InferFileSystem*() functions accept a HANDLE as an alternative to the
already-existing partition path string. These parameters are exclusive
to each other.
- Rename SetPartitionType() -> SetMBRPartitionType(),
and FileSystemToPartitionType() -> FileSystemToMBRPartitionType()
in order to really clarify what they do (since this code is meant
for MBR partitions only, not GPT ones).
[AUTOCHK] Add also support for scanning FATX volumes.
The Format(), FormatEx(), Chkdsk(), ChkdskEx() functions exposed by the
U*.DLL user-mode FS library dlls are different (and have different
prototypes) than the similarly-named functions exported by FMIFS.DLL .
In particular, what we used to call "xxxChkdskEx()" and "xxxFormatEx()"
in our U*.DLL libraries actually correspond more, from their arguments,
to the "Chkdsk()" and "Format()" functions in Windows' U*.DLL . Their
*Ex() counterparts instead take most of the parameters through a
structure passed by pointer.
On FMIFS.DLL side, while FMIFS!Chkdsk() calls U*.DLL!Chkdsk() and
FMIFS!ChkdskEx() calls U*.DLL!ChkdskEx() (and we do not implement these
*Ex() functions at the moment), both FMIFS!Format() and FMIFS!FormatEx()
call U*.DLL!Format() instead, while FMIFS!FormatEx2() calls
U*.DLL!FormatEx() (that we do not implement yet either) !!
To improve that, refactor the calls to these U*.DLL functions so as to
respect the more compatible prototypes: They contain the correct number
of parameters in a compatible order. However, some of the parameters do
not have the same types yet: the strings are kept here in PUNICODE_STRINGS,
while on Windows they are passed via an undocumented DSTRING struct, and
the FMIFS callback is instead a MESSAGE struct/class on Windows.
Finally, the MEDIA_TYPE parameter in U*.DLL!Format() is equivalent, yet
not fully 100% in 1-to-1 correspondence, with the FMIFS_MEDIA_FLAG used
in the corresponding FMIFS.DLL functions.
One thing to notice is that the U*.DLL!Format() (and the Ex) functions
support a BOOLEAN (a flag resp.) for telling that a backwards-compatible
FS version should be used instead of the (default) latest FS version.
This is used e.g. by the FAT FS, where by default FAT32 is selected
(depending also on other constraints like, the disk and the partition
sizes), unless that bit is set in which case, FAT16 (or 12) is used.
The formatter will select it anyway as soon as the partition size
permits it. We make it available internally however so as to "emulate"
FMIFS functionality.
Now rely on the partition filesystem for InstallVBRToPartition() instead
of the unreliable and deprecated partition type.
- Move the actual VBR bootcode installation helpers into fsutil.c
(they depend on the selected filesystem).
- Introduce InstallBootCodeToDisk() and InstallBootCodeToFile()
and bootcode.c helpers, in order to replace the several functions
that were duplicating the same code.
CORE-17312
Hide everything under the same foreground & background colors, so that
the actual color and text blanking reset does not create a visual "blinking".
Then, blank the text and finally reset the actual foreground &
background colors.
We do this because we cannot do the screen scrolling trick that would
allow to change both the text and the colors at the same time (the
function is currently not available in our console "emulation" layer).
Dedicated to the hard work of Joachim Henze! xD
This reverts part of commit 043a98dd (see also commit b2aeafca).
Contrary to what I assumed in commit 043a98dd (and was also assumed in
the older commit b2aeafca), we cannot use the singled-linked lists to
queue and dequeue the PnP device-install events, because:
- the events must be treated from the oldest to the newest ones, for
consistency, otherwise this creates problems, as shown by e.g. CORE-16103;
- the system singled-linked lists only offer access to the top of the
list (like a stack) instead of to both the top and the bottom of the
list, as would be required for a queue. Using the SLISTs would mean
that only the newest-received events would be treated first, while the
oldest (which were the first received) events would be treated last,
and this is wrong.
Therefore one must use e.g. the standard doubly-linked list. Also, using
locked operations (insertion & removal) on the list of device-install
events is necessary, because these operations are done concurrently by
two different threads: PnpEventThread() and DeviceInstallThread().
Since the interlocked linked list functions are not available in user-mode,
we need to use instead locking access through e.g. a mutex.
