| 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_ENABLED |
| 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.enabled=1". |
