GRUB uses a static source TCP port and increments for each new
connection. When rapidly restarting GRUB this can cause issues with some
firewalls that suspect that a reply attack is happening. In addition
GRUB does not ACK the last FIN,ACK when booting the kernel and initrd
from HTTP for example. T
In order to add file system transposition support for UEFI, i.e. the ability
to copy the content of an ISO9660 grub-mkrescue ISO image onto user-formatted
media, and have that boot on UEFI systems, the first thing we need to do is
add support for the file systems that are natively handled by UEFI.
To enable file system transposition support for UEFI, we also must ensure that
there exists a copy of the EFI bootloaders, that are currently embedded in the
efi.img for xorriso, at their expected UEFI location on the ISO9660 file system.
This is accomplished by removing the use of a temporary dir
The final piece we need to add file system transposition support for UEFI
is to ensure that we can locate the boot media regardless of how the boot
partition was instantiated. Especially, we do not want to be reliant on
brittle partition UUIDs, as these only work if a boot media is duplicated at
th
Hello everyone,
This series of patches adds file system transposition support, for UEFI boot
media created with grub-mkrescue.
File system transposition means the ability to take the content of a UEFI
bootable media and copy it, at the file system level, to a partition that was
independently c

256 is a bad modulo. A prime would be a much better one for those purposes.
Also get_time_ms counts up from arbitrary point in time, often boot. I
suggest using some combination of etc and get_time to seed an LFSR algorithm
