We are still working on loading the public keys for kernel signing from the firmware into a kernel keyring, so there's not much point in implementing arch_kexec_kernel_verify_sig without having that first. The same problem also affects IMA: even with these patches, new code still neededs to be added to make IMA use the platform keys for kernel signature verification. -- Thiago Jung Bauermann IBM Linux Technology Center
