The registers that are saved/restored in the trap / exception frame need to be consistent between all entry/exit points as well as the functions that convert between trap/exception frame and context. The trap frame contains only the non-volatile registers and rbp, the rest is saved in the exception frame.
The previous code didn't save rbp in the syscall handler, which led to it being clobbered when exiting though KiServiceExit2 rather than returning back to the syscall exit path. Also KeContextToTrapFrame would use rbx, rsi and rdi from the trap frame, which wouldn't be saved there by the syscall handler.
This fixes invalid contexts being passed to RtlDispatchException. Also update the ExceptionAddress field in the EXCEPTION_FRAME, to match the Rip value in the CONTEXT, which is required for proper unwinding.
- For NT6.0+, NTDLL exports those hash APIs that ADVAPI32 thunks forward to
- Fix undocumented context structure layout and content
- Add apitests to verify both of hash result and structure content
[MMIXER] Implement hadling WAVE_FORMAT_EXTENSIBLE audio format
Fix opening audio device error when trying to open it with WAVE_FORMAT_EXTENSIBLE format tag set in wFormatTag member of WAVEFORMATEX:
- Pass additional data size from WAVEFORMATEX.cbSize to pin data format.
- Append it to the whole size of pin data format (KSDATAFORMAT.FormatSize).
- Set additional fields in WAVEFORMATEXTENSIBLE structure (data format, BPS and channel mask) when WAVE_FORMAT_EXTENSIBLE is used. They are used by our inbuilt Intel AC97 miniport driver at least. It simply fails when these members are not set.
- Fix pin connect allocation size by appending an additional data size from WAVEFORMATEX.cbSize to KSPIN_CONNECT + KSDATAFORMAT + WAVEFORMATEX. This allows to proerly initialize additional extensible data and avoids kernel memory leakage when using extensible audio format.
- Remove format tag check which allowed WAVE_FORMAT_PCM to be opened correctly. So now all possible audio formats can be opened properly at least (although it does not mean they may work correctly).
This fixes the audio playback for all apps those are supporting extensible audio data and use it by default (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium-based browsers, GameDev Tycoon Demo game etc.).

* [KS] Allow passing additional extensible audio data when extensible audio format is used
- Append additional data size from WAVEFORMATEX.cbSize to pin connect size passed to KsCreatePin. If the tag is WAVE_FORMAT_PCM, then this member should always be zero. So in that case, no any additional data is passed to creation request, and the passed data size is correct for PCM too (KSDATAFORMAT + WAVEFORMATEX).
This fixes audio playback in several apps those are supporting extensibble audio and use it by default (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium based browsers, GameDev Tycoon Demo game etc.).

* [WDMAUD.DRV] Pass the correct additional data size to I/O control request
Store a correct size of additional data in WAVEFORMATEX.cbSize when performing open of audio device, when WAVE_FORMAT_EXTENSIBLE audio format is used.
It allows to properly open audio device with Legacy APIs enabled too.
This fixes audio playback in several apps those are using extensible audio data (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium based browsers, GameDevTycoon Demo game etc.).

This can fail on optimized builds, where functions can end after a noreturn function call without an epilog / ret, but with an int 3. We simply fail gracefully, which is the right thing to do.
This also fixes delivering APCs from the system call handler, which previously would have clobbered rax. Also don't use the thread's TrapFrame member, which is not always set, when returning.
- Implement `GetFirmwareType` and improve existing API test for it
- Move (Get/Set)FirmwareEnvironmentVariableEx(A/W) to kernel32_vista_static and export them when NT version >= 6.2
Addendum to 4c8a2a8815. CORE-11954
Simplify code and reduce binary size.
JIRA issue: CORE-19363
- Use shlwapi!QISearch for QueryInterface
implementation.
- Add delay link to shlwapi.
- Define QITABENT macro in <shlwapi.h>.
Follow-up to #6624 (fd96666). ReactOS got rekt in that PR
because kernel32.dll got so larger.
Fix base addresses of DLLs to boot successfully. Sorry.
(dll/ntdll/ldr/ldrutils.c:1423) Illegal DLL relocation!
C:\ReactOS\System32\ntdll.dll overlaps kernel32.dll

shell32!SHRestricted is necessary to make shell working well.
JIRA issue: CORE-11515
- Add dll/win32/shell32/wine/PolicyData.h to define the shell policy data.
- Define POLICYDATA structure and SHELL_NO_POLICY constant
in <shlwapi_undoc.h>.
- Fix shell32!SHRestricted, shell32!SHSettingsChanged,
shlwapi!SHGetRestriction, and shlwapi!SHRestrictionLookup functions.
The definitions in the NDK inline_ntcurrentteb.h and psfuncs.h files are
synced togther with those of winnt.h (in the winnt_old.h generator file).
See commits c1929445d (r49627) and 925c587c8 (r56318).
IMPORTANT NOTE: The ARM64 definition does not exist yet in our headers!
The official MS DDK/WDK does not expose KeGetPcr() for x86, so do
not expose it there as well. Use instead the private NDK definition.
If it were exposed in the DDK/WDK, it would have to be a
multiprocessor-compatible definition.
Note that the broken definition was working only in single-processor
mode, using the PCR static memory pointer value.
The official MS DDK/WDK exposes KeGetPcr() as an alias to such a
PCR value only for IA64, MIPS and PPC, which is of course not great.
Unify the private IMM32 macro
definitions. Refactoring...
JIRA issue: CORE-19361
- Define IS_SPECIAL_HKL macro
in <imm32_undoc.h>.
- Use IS_IME_HKL and
IS_SPECIAL_HKL macros of
<imm32_undoc.h>,
in kbswitch and input modules.
Implementing the back-end of
the Language bar...
JIRA issue: CORE-19361
- Add mlng.cpp and mlng.h.
- Modify msctf.spec.
- Implement MLNGINFO
structure and CStaticIconList
class.
- Implement TF_InitMlngInfo,
TF_MlngInfoCount,
TF_InatExtractIcon,
TF_GetMlngIconIndex, and
TF_GetMlngHKL functions.
This was a MinGW-specific, non-MS-DDK/WDK-compatible define, that was
used to mark NTOS kernel/hal exports, instead of NTSYSAPI etc.
We have since fixed that, and changed the way Freeldr (and rossym)
manages these, see commits:
186c8b72d (r16028), 51f0dfd30 (r17651) and 526efd2ee (r24359)
Used in `ATL::CStringW` and `ATL::CStringA`, for example:
```
ATL::CStringW cswItemText = "";
cswItemText.Preallocate(64);
SendDlgItemMessageW(pdis->CtlID, LB_GETTEXT, pdis->itemID, reinterpret_cast<LPARAM>(cswItemText.GetBuffer()));
cswItemText.ReleaseBuffer();
```
This public function is used to allocate memory for the string via private PrepareWrite, but it's missing somehow. Now it shouldn't be.
