- Correctly probe the FileName user pointer before capturing its contents.
- A paging file name with zero length is invalid too.
- Remember (TODO!) in the code that the lower bounds of the Safe*Size values
need to be checked too!
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.
- Multiboot support added back in FreeLdr MSVC builds so that it can be
booted using e.g. GRUB. See CORE-15563.
- Re-introduce the disk drive mapper code.
As the MSVC linker alone doesn't permit such control, the file uses
ASM language (C can alternatively be used), together with extra linker
command-line switches.
It is pre-processed 3 times: first for generating the ASM code, second
for the C code and the third time for generating the linker response
file.
In our case, the ASM code defines the __bss_start__ and __bss_end__
symbols that allow us to find the limits of the .bss section (which is
by the way automatically appended to the .data section by the MSVC linker).
The C code is used to specify the list of linker switches that can be
passed through the `#pragma comment(linker, ...)' directive (the can be
alternatively specified in the linker response section).
Finally the linker response section contains all the linker switches
that cannot be specified with the `#pragma comment(linker, ...)'
directive.
Using all this we can recycle the BSS initialization code, that has been
written originally for GCC only, also for the MSVC builds.
Also, remove the outdated .text16 section merging.
- Whitespace;
- Explicitly use string pooling (option "/GF"), so that even if it's
used globally in the main ReactOS CMAKE file or not, we still have it
there, because we are quite size-constrained;
- Rename the source lists (OK, we understand it's _COMMON_ ...);
- Remove redundant double inclusion of linuxboot.c;
- In the 'freeldr_common' static library, compile the ASM code first.
Modify the .code16 macro so that the 16-bit code segment can get a
chance to be correctly merged with other (possibly 32-bit) code
segments, without keeping generating multiple .text segments with
different attributes and generating the corresponding LNK4078 warning.
This fixes the warning when compiling NTOSKRNL on MSVC:
"v86.S.obj : warning LNK4078: multiple '.text' sections found with different attributes (C0520040)".
