* 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
* Because we install our own ldlinux.sys, we must ensure that if the ISO contains
an ldlinux.sys in the root directory, this file is not copied over. However, our
comparison for the 'ldlinux.sys' string was case sensitive which means that some
ISOs such as R-Drive Image boot ISO, that use 'LDLINUX.SYS' were trying write over
our file, resulting in a file extraction failure.
* This patch ensures that the string comparison for 'ldlinux.sys' is case insensitive.
* Also add 512px sized icon (upscaled using waifu2x)
