config SECURITY_LOADPIN
bool "Pin load of kernel files (modules, fw, etc) to one filesystem"
depends on SECURITY && BLOCK
help
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.
config SECURITY_LOADPIN_ENFORCE
bool "Enforce LoadPin at boot"
depends on SECURITY_LOADPIN
help
If selected, LoadPin will enforce pinning at boot. If not
selected, it can be enabled at boot with the kernel parameter
"loadpin.enforce=1".
