- Introduce a set of NtLdrGet(Next)Option(Ex) helpers that allow
retrieving respectively, the "next" option in an options string,
and retrieving a given named option in such an options string,
by correctly parsing that string.
Valid syntaxes:
/OPTION1 /OPTION2/OPTION3 OPTION4 /OPTION5(=...) ...
Options separators are slashes, or whitespace (space, tab), mandatory
if no slash is used, and otherwise optional.
- Use these functions wherever NT load options are being parsed.
- Simplify the parsing of /DEBUGPORT=... using these functions.
- When parsing the /HAL=... or /KERNEL=... options, only the first
encountered one is taken into account, any other ones are discarded.
- When parsing the other load options, only their first occurrences are
taken into account, any other repetitions are discarded.
* The NOPAE option overrides any previous PAE option.
* Any NOEXECUTE(=) option should override any previous
NOEXECUTE=ALWAYSOFF (or equivalently, EXECUTE) option.
This parameter is not needed since it's possible to determine, from
within this function, whether or not we are in Setup mode, by just
looking for the presence of a non NULL LoaderBlock->SetupLdrBlock.
Not all files are included, but these are necessary to compile cdrom driver.
So far it can only be statically linked with drivers, a proper
implementation requires wdfldr helper driver
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore
This removes the broken wine version of atexit and onexit. It keeps only dllonexit, which is implemented properly. The previous __call_atexit is moved to where the mingw onexit/atexit code is and adjusts it to work with the existing code. A call to __call_atexit is added in __tmainCRTStartup after the main function was called.
This is required since the NX protection proagates from the highest level, enforcing NX on the entire range, independent of whether lower level P*Es have the bit set or not. It might be useful to add a platform specific constant to allow making page tables NX on architectures that have a different behavior.
* Move MiBuildPfnDatabaseFromPageTables into MiBuildPfnDatabase
* Make sure to call MmInitializeProcessAddressSpace() from the x64 version of MiInitMachineDependent()
* Handle result of MmInitializeProcessAddressSpace in MiInitMachineDependent (Should do the same for x86)
* Remove obsolete x64 debug print
- Deliver pending APCs on trap exit
- Pass the trapframe of KiApcInterrupt to KiDeliverApcs, not NULL.
- Fix parameter passing from KiSwapContext to KiSwapContextInternal and KiSwapContextResume, so that the ApcBypass parameter is not uninitialized
- Fix return value of KiSwapContextResume to correctly indicate whether we want to have APCs directly delivered or not (when there are non, or when delivery is suppressed)
The previous version (like the x86 one) used a combination of C and asm code, called from C code to switch the stack. This is problematic, since there is no guarantee what assumptions C code makes about the stack (i.e. it can place any kind of stack pointers into registers or on the stack itself.) The new algorithm returns back to the systemcall entry point in asm, which then calls KiConvertToGuiThread, which is also asm and calls KeSwitchKernelStack ...
To be 100% correct and not rely on assumptions, stack switching can only be done when all previous code - starting with the syscall entry point - is pure asm code, since we can't rely on the C compiler to not use stack addresses in a way that is not transparent. Therefore the new code uses the same mechanism as for normal system calls, returning the address of the asm function KiConvertToGuiThread, which is then called like an Nt* function would be called normally. KiConvertToGuiThread then allocated a new stack, switches to it (which is now fine, since all the code is asm), frees the old stack, calls PsConvertToGuiThread (which now will not try to allocate another stack, since we already have one) and then jumps into the middle of KiSystemCallEntry64, where the system call is handled again.
Also simplify KiSystemCallEntry64 a bit by copying the first parameters into the trap frame, avoiding to allocate additional stack space for the call to KiSystemCallHandler, which now overlaps with the space that is allocated for the Nt* function.
Finally fix the locations where r10 and r11 are stored, which is TrapFrame->Rcx and TrapFrame->EFlags, based on the situation in user mode.
* [COMPILER_APITEST] Import MS EH/SEH tests
Taken from https://github.com/microsoft/compiler-tests
* [CRT] Add missing declaration of _longjmpex
* [COMPILER_APITEST] Add cmake build files for MS SEH test
It is built as a static library
* [COMPILER_APITEST] Fix GCC build of MS SEH tests
There are a number of hacks in there now. Also the volatile hacks should be separated and sent upstream.
