This allows separating the system keyring certificate from the kernel build process. After the kernel image is distributed, the insert-sys-cert script can be used to insert the certificate for x86. Changes: v5: * Added CRC fixing (3/4) v4: * Applied checkpatch.pl suggestions (2/4, 3/4) * Cleaned up the commit messages (1/4, 2/4) * Added the build file to .gitignore (1/4) v3: * Rewrote 1/4 to insert incompressible bytes are at build time. Previous solution required changes to /boot/Makefile's for modifying the vmlinux file after linking, and did not work well with cross compilation. * Added 2/4 for ELF class-independent processing of vmlinux file, in case the script was compiled for 64-bit and the kernel was compiled for 32-bit. * Reordered 3/4, added x86 bzImage boot version (>=2.08) verification. v2: * Rebased arch/boot/x86/Makefile patch (removed in v3) Mehmet Kayaalp (4): KEYS: Insert incompressible bytes to reserve space in bzImage KEYS: Add ELF class-independent certificate insertion support KEYS: Support for inserting a certificate into x86 bzImage KEYS: Print insert-sys-cert information to stdout instead of stderr certs/.gitignore | 1 + certs/Makefile | 21 +- certs/system_certificates.S | 2 +- scripts/Makefile | 1 + scripts/insert-sys-cert.c | 473 +++++++++++++++++++++++++++++++++----------- 5 files changed, 381 insertions(+), 117 deletions(-) -- 2.7.4
