* We distractedly chose to populate the message from our protective MBR
for GPT/UEFI-only boot media into the 4KB that directly followed the
MBR, which of course is space that is being used by the primary GPT.
* This resulted on systems having to fall back to using the secondary
GPT, which not all appear to be designed to do.
* Alter the code to ensure the protective message is written at LBA 34,
after the primary GPT.
* Closes#1507
* If a converted label contains mostly underscore, the proposed
label is used for FAT32 instead. However this label still has
the KB/MB/GB symbols localized so it may be invalid.
* Ensure that we use a non-localized version of the size when
using such a label.
* Closes#1506.
* Also fix a VS2019 static analysis warning in net.c.
* The upcoming Ubuntu 20.04 comes with MD5 validation turned on by default.
* When creating persistent boot media, we may update some of the validated files
to add persistence, update the search labels, etc.
* Make sure that the files we modify get their MD5 updated where needed.
* Also add 'loopback.cfg' to the list of config files we can add persistence to.
* Part of #1499
* Among other nefarious things, ubuntu 20.04 added a $casper_flavour suffix
to their grub.cfg /casper/vmlinuz kernel option, so we can no longer rely
on 'persistent' being inserted in a proper location.
* Switch to latching on file=/cdrom/preseed and hope that it will work for
all of Ubuntu & derivatives.
* Part of #1499.
* Commit 4c5adf092e moved us away from using CreateFile()
when extracting a file on the target media, and as such the error code returned when
failing to create an 'autorun.inf' due to a security solution has shifted.
* Make sure we handle the new error and don't bail out on 'autorun.inf' creation.
* Also update the actual name of the RtlDosPathNameToNtPathNameXXX function we use.
* Closes#1496
* Recent versions of Windows can set the deafult locale to codepage 65001 (UTF-8).
* This produces an assert due to a missing entry in cp_hr_list[], so fix that.
* However, this fix alone is not enough, as a GetOEMCP() that returns 65001 means
that any systems set to UTF-8 will fall back to codepage 437 for DOS, which is
definitely not what we want => Add an extra call to determine the actual OEM
codepage when UTF-8 is detected.
* Closes#1468
* Commit [e522ef6c55] (PR #1426) regressed the '%s'
progress messages back to '%0.1f%%' which results in the percentage remaining at
zero when the UI is in German.
* Surround macro params to ensure expected results
* Fix copy-paste errors
* Fix a potential buffer overflow in SetSectionHeaders()
* Add const modifier where relevant
* Use GetWindowLongPtr() everywhere
* Use proper sprintf format for unsigned int
* Use %s for printf-like funcs (https://www.viva64.com/en/w/v618/print/)
* Closes#1464
* 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
