[PATCH v2 0/4] efi: libstub enhancements for cmdline parsing and kaslr

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This adds support for the 'quiet' kernel command line parameter, so
that meaningless debug prints can be prevented from corrupting the
boot splash (#3)

Secondly, it enables randomization of the UEFI runtime services region when
KASLR is in effect (#4)

Patches #1 and #2 are preparatory cleanup patches. Patch #4 trivially depends
on #2 which is why they are part of the same series.

v2: - Fix x86 breakage caused by the fact that CONFIG_CMDLINE is not guaranteed
      to be defined on that architecture. So instead, preserve the original x86
      behavior, and move th handling of CONFIG_CMDLINE_FORCE back to the ARM
      code.
    - Add Mark's ack.

Ard Biesheuvel (4):
  efi/libstub: fix harmless command line parsing bug
  efi/libstub: unify command line param parsing
  efi/libstub: arm/arm64: disable debug prints on 'quiet' cmdline arg
  ef/libstub: arm/arm64: randomize the base of the UEFI rt services
    region
