Hello, this patch (v2) implements UKI support for kexec_file_load. It will require support in the kexec-tools userspace utility. For testing purposes the following can be used: https://github.com/Cydox/kexec-test/ Creating UKIs for testing can be done with ukify (included in systemd), sbctl, and mkinitcpio, etc. There has been discussion on this topic in an issue on GitHub that is linked below for reference. Changes for v2: - .cmdline section is now optional - moving pefile_parse_binary is now in a separate commit for clarity - parse_pefile.c is now in /lib instead of arch/x86/kernel (not sure if this is the best location, but it definetly shouldn't have been in an architecture specific location) - parse_pefile.h is now in include/kernel instead of architecture specific location - if initrd or cmdline is manually supplied EPERM is returned instead of being silently ignored - formatting tweaks Some links: - Related discussion: https://github.com/systemd/systemd/issues/28538 - Documentation of UKIs: https://uapi-group.org/specifications/specs/unified_kernel_image/ Jan Hendrik Farr (2): move pefile_parse_binary to its own file x86/kexec: UKI support arch/x86/include/asm/kexec-uki.h | 7 ++ arch/x86/kernel/Makefile | 1 + arch/x86/kernel/kexec-uki.c | 126 +++++++++++++++++++++++++ arch/x86/kernel/machine_kexec_64.c | 2 + crypto/asymmetric_keys/mscode_parser.c | 2 +- crypto/asymmetric_keys/verify_pefile.c | 110 +++------------------ crypto/asymmetric_keys/verify_pefile.h | 16 ---- include/linux/parse_pefile.h | 32 +++++++ lib/Makefile | 3 + lib/parse_pefile.c | 109 +++++++++++++++++++++ 10 files changed, 292 insertions(+), 116 deletions(-) create mode 100644 arch/x86/include/asm/kexec-uki.h create mode 100644 arch/x86/kernel/kexec-uki.c create mode 100644 include/linux/parse_pefile.h create mode 100644 lib/parse_pefile.c -- 2.40.1 _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
