Instead of being enabled by default when SECURITY_LOADPIN is selected, provide an additional (default off) config to determine the boot time behavior. As before, the "loadpin.enabled=0/1" kernel parameter remains available.

Any files read through the kernel file reading interface
|
|
(kernel modules, firmware, kexec images, security policy)
|
|
can be pinned to the first filesystem used for loading. When
|
|
enabled, any files that come from other filesystems will be
|
|
rejected. This is best used on systems without an initrd that
|
|
have a root filesystem backed by a read-only device such as
|
|
dm-verity or a CDROM.

If selected, LoadPin will enforce pinning at boot. If not
|
|
selected, it can be enabled at boot with the kernel parameter
|

"loadpin.enabled=1".
