For secureboot, as a first step in that direction, I just wrote some code
to sign elf executable and be able to verify it in kernel upon exec(). I
am soon planning to post RFC code (most likely next week).
Hopefully we will be able to sign statically signed /sbin/kexec, give
it extra capability (upon signature verification) to be able to call
sys_exec().
Thanks
