+ KdpDebugLogInit: Add resources cleanup in failure code paths.
Fix, in an NT-compatible manner, how (and when) the KD/KDBG BootPhase >=2
initialization steps are performed.
These are necessary for any functionality KDBG needs, that would depend
on the NT I/O Manager and the storage and filesystem stacks to be running.
This includes, creating the debug log file, and for KDBG, loading its
KDBinit initialization file.
As a result, file debug logging is fixed.
The old ReactOS-specific (NT-incompatible) callback we did in the middle
of IoInitSystem() is removed, in favor of a runtime mechanism that should
work on Windows as well.
The idea for this new mechanism is loosely inspired by the TDL4 rootkit,
see http://blog.w4kfu.com/public/tdl4_article/draft_tdl4article.html
but contrary to it, a specific hook is used instead, as well as the
technique of driver reinitialization:
https://web.archive.org/web/20211021050515/https://driverentry.com.br/en/blog/?p=261
Its rationale is as follows:
We want to be able to perform I/O-related initialization (starting a
logger thread for file log debugging, loading KDBinit file for KDBG,
etc.). A good place for this would be as early as possible, once the
I/O Manager has started the storage and the boot filesystem drivers.
Here is an overview of the initialization steps of the NT Kernel and
Executive:
----
KiSystemStartup(KeLoaderBlock)
if (Cpu == 0) KdInitSystem(0, KeLoaderBlock);
KiSwitchToBootStack() -> KiSystemStartupBootStack()
-> KiInitializeKernel() -> ExpInitializeExecutive(Cpu, KeLoaderBlock)
(NOTE: Any unexpected debugger break will call KdInitSystem(0, NULL); )
KdInitSystem(0, LoaderBlock) -> KdDebuggerInitialize0(LoaderBlock);
ExpInitializeExecutive(Cpu == 0): ExpInitializationPhase = 0;
HalInitSystem(0, KeLoaderBlock); <-- Sets HalInitPnpDriver callback.
...
PsInitSystem(LoaderBlock)
PsCreateSystemThread(Phase1Initialization)
Phase1Initialization(Discard): ExpInitializationPhase = 1;
HalInitSystem(1, KeLoaderBlock);
...
Early initialization of Ob, Ex, Ke.
KdInitSystem(1, KeLoaderBlock);
...
KdDebuggerInitialize1(LoaderBlock);
...
IoInitSystem(LoaderBlock);
...
----
As we can see, KdDebuggerInitialize1() is the last KD initialization
routine the kernel calls, and is called *before* the I/O Manager starts.
Thus, direct Nt/ZwCreateFile ... calls done there would fail. Also,
we want to do the I/O initialization as soon as possible. There does
not seem to be any exported way to be notified about the I/O manager
initialization steps... that is, unless we somehow become a driver and
insert ourselves in the flow!
Since we are not a regular driver, we need to invoke IoCreateDriver()
to create one. However, remember that we are currently running *before*
IoInitSystem(), the I/O subsystem is not initialized yet. Due to this,
calling IoCreateDriver(), much like any other IO functions, would lead
to a crash, because it calls
ObCreateObject(..., IoDriverObjectType, ...), and IoDriverObjectType
is non-initialized yet (it's NULL).
The chosen solution is to hook a "known" exported callback: namely, the
HalInitPnpDriver() callback (it initializes the "HAL Root Bus Driver").
It is set very early on by the HAL via the HalInitSystem(0, ...) call,
and is called early on by IoInitSystem() before any driver is loaded,
but after the I/O Manager has been minimally set up so that new drivers
can be created.
When the hook: KdpInitDriver() is called, we create our driver with
IoCreateDriver(), specifying its entrypoint KdpDriverEntry(), then
restore and call the original HalInitPnpDriver() callback.
Another possible unexplored alternative, could be to insert ourselves
in the KeLoaderBlock->LoadOrderListHead boot modules list, or in the
KeLoaderBlock->BootDriverListHead boot-driver list. (Note that while
we may be able to do this, because boot-drivers are resident in memory,
much like we are, we cannot insert ourselves in the system-driver list
however, since those drivers are expected to come from PE image files.)
Once the KdpDriverEntry() driver entrypoint is called, we register
KdpDriverReinit() for re-initialization with the I/O Manager, in order
to provide more initialization points. KdpDriverReinit() calls the KD
providers at BootPhase >= 2, and schedules further reinitializations
(at most 3 more) if any of the providers request so.

de-DE: Harmonize the length of IDC_COMPUTERNAME with IDC_ADMINPASSWORD1 and IDC_ADMINPASSWORD2
which looks better and is already done like that in en-US.
de-DE: Also harmonize some 2nd stage captions. Some were named "Setup" and some were
named "Installation". I harmonized to "Setup" everywhere as that is what is also used in
1st stage, is shorter and no german person will have any issue understanding
that. It is also more likely to be kept in sync in the future if new dlgs would
be added, as it is the same word as used in en-US.
de-DE: Align the IDC_PROJECTS with the GPL button (which is slightly more wide in de-DE).
All languages:
Use same width for IDC_PRODUCT_OPTIONS as for IDC_PRODUCT_DESCRIPTION.
- KdbSymInit() in kdb_symbols.c only initializes symbols implementation
support.
- The rest of KdbInitialize gets moved into kdb_cli.c and initializes
the KDBG debugger itself.
- Move KdbDebugPrint to kdb_cli.c as well.
Win2K3 just wraps in SEH only this syscall, which appears pointless
and was removed since NT6.0. We remove it too as an experiment.
Revert the change that added SEH here from commit 6d97180 (r52899).
Access check is an expensive operation, that is, whenever an access to an
object is performed an access check has to be done to ensure the access
can be allowed to the calling thread who attempts to access such object.
Currently SepAnalyzeAcesFromDacl allocates a block of pool memory for
access check rights, nagging the Memory Manager like a desperate naughty
creep. So instead initialize the access rights as a simple variable in
SepAccessCheck and pass it out as an address to SepAnalyzeAcesFromDacl so
that the function will fill it up with access rights. This helps with
performance, avoiding wasting a few bits of memory just to hold these
access rights.
In addition to that, add a few asserts and fix the copyright header on
both se.h and accesschk.c, to reflect the Coding Style rules.
This mutes a lot of debug spam that fills up the debugger when an access
check fails because a requestor doesn't have enough privileges to access
an object.
Implement _wsystem(), by referring system().
Improve system().
Use WaitForSingleObject in system() and _wsystem().

that we do lack for todays master: e.g._ kbdeo, kbdsf, kbdrost
and also some that we lacked in the past
(for improving backwards compatibility of the script to older rls-branches):
kbdgm, kbdes, kbdgrist, kbdja, kbdko, kbdsk, kbdsk1

The whole-word search of Notepad had a bug around punctuation. For example, the text "Windows" didn't match in the text "MS-DOS,Windows,ReactOS". Use _istalnum instead of _istspace. Fix the position to check. _istalnum matches an alphabet letter or numeric digit. CORE-18837
- Add Shift+F3 accelerator as command CMD_SEARCH_PREV.
- Extend DIALOG_SearchNext function with bDown argument for the action of CMD_SEARCH_PREV.
