* Status code assignation was removed when the original code
was altered to use pfNtFsControlFile(). Fix that and also
make the code more similar to other calls.
* Closes#1459
* msg.S now reads an ASCII message (with escaped colour sequences)
from the following blocks, which is both more flexible and allows
for more content to be displayed.
* Also adds Bochs testing to the MBR build facility
* Hopefully using DICS_FLAG_CONFIGSPECIFIC instead of DICS_FLAG_GLOBAL is all that was needed
to get device disabling/re-enabling work without creating zombie devices, because we sure
need to force Windows' hand when it comes to detecting logical volumes...
* Implement CreatePreallocatedFile() which uses NtCreateFile() to create files with preallocated sizes.
This is used during ISO extraction to improve performance.
* Remove now-unused preallocate_filesize which was called after CreateFileU().
* Closes#1445
* ClearMBRGPT() attempts to write WRITE_RETRIES times, even if all those times succeed.
* Instead, skip the remaining retries on success.
* Also improve code readability.
* Closes#1454
* So, as it happens, when assigning the product of two 32-bit variables into a 64-bit one,
compilers default to being *DUMB* and, against all reasonable expectations, do not perform
that multiplication as a 64-bit operation (even when the code is compiled as x64). Wow,
that's really great decision making by compiler designers if I ever saw some... Whoever
decided that C developers would much rather want truncation and 32-bit overflows, instead
of the expected *LOGICAL* behaviour of conducting arithmetic operations as 64-bit when the
result will be assigned to a 64-bit variable, need to be condemned to a lifetime of trying
to help elderly folks trying to conduct simple computing tasks as a punishment...
Anyhoo, nt_write_blk()'s offset.QuadPart = block * channel->block_size + nt_data->offset
was overflowing 32-bit as soon as block * channel->block_size went over the 4 GB mark,
with the disastrous results one can expect. Considering that this is code we practically
lifted verbatim from e2fsprogs, I guess e2fsprogs' NT I/O manager was never properly
tested with anything larger than a 4 GB. Awesome!
* We fix the above by doing what unix_io.c does and setting the 32-bit read/write_blk()
calls to be wrappers around their 64-bit counterpart (since, once you deal with a 64-bit
block variable, the computation is conducted as 64-bit).
* Also remove a bunch of stuff we don't need from config.h
* Closes#1396
* Fix use of EXT2_BLOCK_SIZE() instead of EXT2_INODE_SIZE() during inode
initialization, that made us zero way many more blocks than was needed.
* Also disable sparse_super feature and improve block setup.
* Also explicitly use IS_POWER_OF_2 macro where required.
* Most distros (Debian, Ubuntu) have moved to using Sylinus 6.04 even
as it has NOT officially been released, so we want our fallback to
work against this too.
* pre1 since the Syslinux folks advise against using pre2 or later...
* Closes#1444
* Only applies for blank UEFI:NTFS drives for now. UEFI:NTFS Windows drives are
still set to use NTFS only (since Windows 7 doesn't support UEFI exFAT boot).
* While compressed EFI bootloaders are not an issue for UEFI:NTFS, some UEFI firmwares
embed an NTFS driver that doesn't support NTFS compression.
To address that, also uncompress the EFI bootloaders on NTFS.
* Closes#1424
Yet another link in the long chain of Microsoft making it UNFATHOMABLY DIFFICULT
to figure out what version of Windows an application is actually running on...
* When using compressed NTFS, having a compressed bootmgr prevents BIOS boot, so we
now call `compress -u` where needed to leave the relevant bootmgr files uncompressed.
* Closes#1381
* Also fix a minor warning in ext2fs
* Windows platforms prior to Windows 10 1703 cannot access any logical partition besides the
first one (we don't even get a volume for those).
* This fix enables the use of physical + offset for ext# formatting to work around this,
which is file since we don't actually need to mount the partition.
* Also fix ext2fs_open2() not handling normalized versions of Windows drive paths ("\\?\...")
* Also fix an issue where we would make the drive letter unavailable after formatting a
standalone partition to ext#.
* Also ensure that we return an error if the drive we attempt to locate a partition on
through an offset does not match the currently selected one.
* Also remove some unused calls in drive.c.
* Closes#1374
* While we need to detect that 'txt.cfg' is a Syslinux config file, so that
we can alter it for persistence, it should never be used as a main config
file, such as the one we link to when we create /syslinux.cfg.
* Closes#1375
