The UEFI shim provides what is called Machine Owner Keys (MOK). Shim uses both the UEFI Secure Boot DB and MOK keys to validate the next step in the boot chain. The MOK facility can be used to import user generated keys. These keys can be used to sign an end-users development kernel build. When Linux boots, both UEFI Secure Boot DB and MOK keys get loaded in the Linux .platform keyring. Add a new Linux keyring called .mok. This keyring shall contain just MOK keys and not the remaining keys in the platform keyring. This new .mok keyring will be used in follow on patches. Unlike keys in the platform keyring, keys contained in the .mok keyring will be trusted within the kernel if the end-user has chosen to do so.

When this UEFI variable is set, it indicates the end-user has made the decision themself that they wish to trust MOK keys within the Linux trust boundary. It is not an error if this variable does not exist. If it does not exist, the MOK keys should not be trusted within the kernel. MOK variables are mirrored from Boot Services to Runtime Services. When shim sees the new MokTML BS variable, it will create a new variable (before Exit Boot Services is called) called MokListTrustedRT without EFI_VARIABLE_NON_VOLATILE set. Following Exit Boot Services, UEFI variables can only be set and created with SetVariable if both EFI_VARIABLE_RUNTIME_ACCESS & EFI_VARIABLE_NON_VOLATILE are set. Therefore, this can not be defeated by simply creating a MokListTrustedRT variable from Linux, the existence of EFI_VARIABLE_NON_VOLATILE will cause uefi_check_trust_mok_keys to return false.

With the addition of the new mok keyring, the end-user may choose to trust MOK keys. Introduce a new keyring handler specific for mok keys. If mok keys are trusted by the end-user, use the new keyring handler instead.

If they have chosen to trust them, the .mok keyring will contain these keys. If not, the mok keyring will always be empty. Update the restriction check to allow the ima keyring to also trust mok keys when the secondary keyring is also trusted.
