This is a partial sync of the CRT library with wcsrtombs_l and _mbstowcs_l functions from WINE. The _wctomb_s_l implementation of WINE which is used by _wctomb_s, _wctomb_l and wctomb brings failed results of the wctomb unit testcase and at the same time it crashes the whole testcase after.
Therefore I will not address the wctomb function for the moment being.
The current _mbtowc_l code directly passes the string count size argument to cbMultiByte argument parameter to MultiByteToWideChar(). As the size of lpMultiByteStr expressed in bytes by cbMultiByte is dependent of the actual given string, the size of lpWideCharStr expressed in characters by cchWideChar is always 1.
The resulting parameters to MultiByteToWideChar() will lead to a failure as lpWideCharStr cannot accommodate the converted string if the size pointed by lpMultiByteStr is larger than the buffer wide string to receive the converted output, a Win32 error code of ERROR_INSUFFICIENT_BUFFER in other words. The fact that _mbtowc_l never fails without WINE Gecko package installed is because the codepage pointed by lc_codepage is CP_ACP and the converted output is directly given to the destination wide string parameter thus never calling MultiByteToWideChar(). Installing WINE Gecko merely unhides this problem.
As _mbtowc_l is imported from WINE and that they have updated their code (which at the same time this fixes the aforementioned problem), the following commit syncs the updated code from WINE.
CORE-16885
Incoming r4 contains the number of dwords to allocate, converting to bytes then return.
This makes ReactOS applications compiled for ARM running on true ARM Windows.
Reference: 2b095beace
Native CRT on ARM & ARM64 Windows doesn't have these functions.
For compatibility, it's mandatory to not have it at all. Otherwise,
ARM executables built for ReactOS do not run on true ARM Windows.
Consider doing full sync with mingw-w64 CRT in future.
This small win32 library provides time-zone utility wrappers around
Win32 functions, that are used by different ReactOS modules such as
timedate.cpl, syssetup.dll, and a possible future 'tzutil' tool.
The code has been extracted from the common code found in both
timedate.cpl and syssetup.dll.
- No need to use a PCH when compiling a 1-file library.
- Add the _NTSYSTEM_ definition.
- Since the arbiter.h file is to be included by the users of this
library, namely only kernel-mode NT components (incl. NTOS), there
is no need to include the standard kernel-mode headers in it.
Include these headers instead in the private implementation of the
library, arbiter.c.
Pierre recommended this workaround for 0.4.8rls before.
Avoids "GetVolumeInformation now fails on NFS volume"
This workaround was recurrently applied for all releases
0.4.8, 0.4.9, 0.4.10, 0.4.11, 0.4.12, 0.4.13.
I never got any reply in the regression-ticket and recurrently
applying this over and over again is a waste of time.
So I decided to commit to master today, but will leave
the ticket unresolved, so when a proper fix will arrive in the future,
the existing ticket will remind us to undo this workaround.
Please note that I replaced #if 0 with #if 1
as discussed with Pierre. That's different to the patch in ticket.
which implements the required functionality.
ntdll and ntoskrnl now have a wrapper for this, with SEH.
This protects the function against malformed / bad images,
whilst still being able to use the code in freeldr et al.
Idea from Thomas.
CORE-14857
The code is mostly unchanged. This includes the following changes:
* Move all wine code to crt/wine to keep it separated from our own code
* Add a minimal winternl.h
* Remove the asm macros from wine/config.h
* Include wine/asm.h where required
* Fix the names of the exported functions (GCC uses thiscall now and no wrappers are used anymore)
The autogenerated name has the format:
"ATL:<hexadecimal_digits_of_pointer><NULL-terminator>"
and the number of hex digits in 0xABCD1234 (for 32-bit == 4-byte)
pointers (without the '0x') is 8 == 4*2, and for 64-bit == 8-byte
pointers (e.g. 0xABCDEF0123456789) is 16 == 8*2.
Dynamically check for sys/types.h and pid_t in wine config.h
Use TARGET_xxx defines instead of _X86_ as this is undefined by GCC
Add some sense in include directories management by using interface
libraries
This adds an evil hack to persuade libstdc++, which tries to import __acrt_iob_func from a DLL.
This can only be solved cleanly by adding a GCC-compatible C++ standard library to our tree later.
This fixes the crashes in HvpGetCellMapped on Windows Server 2003 when booting from Freeloader, as mentioned in maharmstone/btrfs#16.
When the bootloader loads the system hive, it cleans the data pertaining to any volatile keys. The Windows bootloader does this by setting SubKeyCounts[Volatile] to 0. After boot, the kernel marks any cell where this is 0 but SubKeyLists[Volatile] isn't HCELL_NIL as dirty, meaning that the sanitized version will then get flushed to the disk.
Because Freeloader sets SubKeyLists[Volatile] to HCELL_NIL straightaway, Windows thinks the cell is clean, and can unload it without flushing. If it then reads it from the disk, it will crash in HvpGetCellMapped due to the stale volatile pointers.
If you break on nt!CmpInitializeSystemHive on Windows and "gu" to the let the function run, you'll see that DirtyVector of the HHIVE has only the first 8 bits set. If you run it using the official bootloader, it'll have a lot more than that.
- kernel32!BaseCreateStack() is compatible with ntdll!RtlpCreateUserStack().
- When checking whether a stack guard page can be added, its size has to
be accounted for in the checking logic.
- We have to satisfy the PEB::MinimumStackCommit constraint.
- We cannot use PEB::GuaranteedStackBytes in BaseCreateStack() since it is
nowhere initialized (default is 0). It gets initialized to a non-zero
value when the user manually calls SetThreadStackGuarantee().

- RtlpCreateUserStack(): Fix memory leak in failure case.
- RtlpFreeUserStack() doesn't need to return anything.

These are required by latest mingw-w64 stl and we are mixing this with our crt headers.
Define _CRT_NO_POSIX_ERROR_CODES in all modules that define their own constants.

so use the same code in hid.dll and in hidparse.sys

There is no need to compile our DLLs as shared libraries since we are

MSVC was previously given a "result" variable to copy the fscale result from st(0). This led to another "fld" FPU stack push at the very end without popping the source value from the FPU stack.
Moreover, this copy isn't even needed: A simple "fstp st(1)" at the end pops an element from the FPU stack while effectively storing the result in st(0), the register used for returning a double value.
This problem didn't affect GCC, as it is only given the "fscale" instruction and does all necessary stack operations itself.
However, looking into the CRT sources, I found many other i386 implementations with inline assembly suffering from the same problem.
Fortunately, they have been replaced by pure assembly implementations a while ago, so it's time to finally remove them.
ldexp would have also been a candidate for a pure assembly implementation, but the required check for NaN and setting errno (verified on Win2003) already outweighs the benefits.
And we cannot just do a NaN check with FUCOMI as this is an i686/pentiumpro instruction while we're still targeting i586/pentium.
I'm also using this opportunity to clean up the ldexp.c header and only put in the remaining contributors as returned by "git blame".
Thanks to NightWolve1975 for reporting the problem! (https://twitter.com/nightwolve1975/status/1099042477531643912)
Clang-CL does not support #pragma function like CL. The alternative to this approach is to disable all intrinsics for this single source file, but that is not trivial to do, as it can only be done by removing a compiler switch, which we have no CMake support for. Therefore this solution is simpler and as good.
Running out of pool is likely at least during kmtest:ExPools.
There is a chance of crashing when dereferencing these null pointers -- but
worse, there's also a chance of overwriting the IVT or BDA if a VDM BIOS
call is in progress, which can lead to crashes in non-obvious places later.

- The default format is used when no format name is specified: this is
the one we use so far in ReactOS:
<debug_class>:(<file>:<line>) <message>
with "debug_class" being "trace", "warn", "err".
- The "wine" format is the one used by Wine. It can be used when trying
to diff-compare traces for a module with the corresponding one
obtained from a Wine run. It can also be useful because the logging of
Wine-synced code assumes that the function names are automatically
added by the helper macros "FIXME()", "TRACE()", "WARN()" or "ERR()",
and not manually inside the logging string given to these macros:
for example:
FIXME("(%params) message\n", params);
displays:
fixme:<module>:SomeFunc(params) message
- The "extended" (or "ext") format is very noisy and tries to output a
lot of information; it is a hybrid of the previous two formats:
<debug_class>:(<file>:<line>):<channel>:SomeFunc <message>
Support for displaying the current process ID is added in
addition to the already existing support for thread ID.
And, don't emit \r\n when an \r alone is encountered.
This fixes the problem of extra newlines appearing when redirecting
"more" output to a file.

GAS uses ".double" symbol for declaring floating-point constants and
".quad" symbol for declaring 64-bit numbers.
This is not compatible with our macro for MASM and introduces bugs.
Now 64-bit constants are supposed to be declared using ".quad" macro.
This is required, since newer versions of MSVC demand that non-member operator new/delete are in the global namespace and neither static nor inline. See https://msdn.microsoft.com/en-us/library/mt723604.aspx ("Overloaded operator new and operator delete")
Otherwise fall back to the computed argv[0].
This is expected by some applications, for example Git.
Code is adapted from Wine.

Our implementation had a bug that could be triggered while
building our USBD library on ReactOS: the compare function
could be called with a NULL pointer instead of a valid value.
With this bug fixed (and the cmd hack in CORE-14648), ReactOS
can totally selfhost :-)! I was able to build LiveCD and BootCD
without any trouble, crash, deadlock or whatever.
(Next step: having a buildbot slave hosted on ReactOS ;-)).
