This option makes kernel signature verification mandatory for
- kexec_file_load() syscall. If kernel is signature can not be
- verified, kexec_file_load() will fail.
-
- This option enforces signature verification at generic level.
- One needs to enable signature verification for type of kernel
- image being loaded to make sure it works. For example, enable
- bzImage signature verification option to be able to load and
- verify signatures of bzImage. Otherwise kernel loading will fail.
+ the kexec_file_load() syscall.
+
+ In addition to that option, you need to enable signature
+ verification for the corresponding kernel image type being
+ loaded in order for this to work.
