+
+config MODULE_SIG_KEY
+ string "File name or PKCS#11 URI of module signing key"
+ default "certs/signing_key.pem"
+ depends on MODULE_SIG
+ help
+ Provide the file name of a private key/certificate in PEM format,
+ or a PKCS#11 URI according to RFC7512. The file should contain, or
+ the URI should identify, both the certificate and its corresponding
+ private key.
+
+ If this option is unchanged from its default "certs/signing_key.pem",
+ then the kernel will automatically generate the private key and
+ certificate as described in Documentation/admin-guide/module-signing.rst
+
+config SYSTEM_TRUSTED_KEYRING
+ bool "Provide system-wide ring of trusted keys"
+ depends on KEYS
+ depends on ASYMMETRIC_KEY_TYPE
+ help
+ Provide a system keyring to which trusted keys can be added. Keys in
+ the keyring are considered to be trusted. Keys may be added at will
+ by the kernel from compiled-in data and from hardware key stores, but
+ userspace may only add extra keys if those keys can be verified by
+ keys already in the keyring.
+
+ Keys in this keyring are used by module signature checking.
+
+config SYSTEM_TRUSTED_KEYS
+ string "Additional X.509 keys for default system keyring"
+ depends on SYSTEM_TRUSTED_KEYRING
+ help
+ If set, this option should be the filename of a PEM-formatted file
+ containing trusted X.509 certificates to be included in the default
+ system keyring. Any certificate used for module signing is implicitly
+ also trusted.
+
+ NOTE: If you previously provided keys for the system keyring in the
+ form of DER-encoded *.x509 files in the top-level build directory,
+ those are no longer used. You will need to set this option instead.
+
+config SYSTEM_EXTRA_CERTIFICATE
+ bool "Reserve area for inserting a certificate without recompiling"
+ depends on SYSTEM_TRUSTED_KEYRING
+ help
+ If set, space for an extra certificate will be reserved in the kernel
+ image. This allows introducing a trusted certificate to the default
+ system keyring without recompiling the kernel.
+
+config SYSTEM_EXTRA_CERTIFICATE_SIZE
+ int "Number of bytes to reserve for the extra certificate"
+ depends on SYSTEM_EXTRA_CERTIFICATE
+ default 4096
+ help
+ This is the number of bytes reserved in the kernel image for a
+ certificate to be inserted.
+
+config SECONDARY_TRUSTED_KEYRING
+ bool "Provide a keyring to which extra trustable keys may be added"
+ depends on SYSTEM_TRUSTED_KEYRING
+ help
+ If set, provide a keyring to which extra keys may be added, provided
+ those keys are not blacklisted and are vouched for by a key built
+ into the kernel or already in the secondary trusted keyring.
+
+config SYSTEM_BLACKLIST_KEYRING
+ bool "Provide system-wide ring of blacklisted keys"
+ depends on KEYS
+ help
+ Provide a system keyring to which blacklisted keys can be added.
+ Keys in the keyring are considered entirely untrusted. Keys in this
+ keyring are used by the module signature checking to reject loading
+ of modules signed with a blacklisted key.
+
+config SYSTEM_BLACKLIST_HASH_LIST
+ string "Hashes to be preloaded into the system blacklist keyring"
+ depends on SYSTEM_BLACKLIST_KEYRING
+ help
+ If set, this option should be the filename of a list of hashes in the
+ form "<hash>", "<hash>", ... . This will be included into a C
+ wrapper to incorporate the list into the kernel. Each <hash> should
+ be a string of hex digits.
+
+config SYSTEM_REVOCATION_LIST
+ bool "Provide system-wide ring of revocation certificates"
+ depends on SYSTEM_BLACKLIST_KEYRING
+ depends on PKCS7_MESSAGE_PARSER=y
+ help
+ If set, this allows revocation certificates to be stored in the
+ blacklist keyring and implements a hook whereby a PKCS#7 message can
+ be checked to see if it matches such a certificate.
+
+config SYSTEM_REVOCATION_KEYS
+ string "X.509 certificates to be preloaded into the system blacklist keyring"
+ depends on SYSTEM_REVOCATION_LIST
+ help
+ If set, this option should be the filename of a PEM-formatted file
+ containing X.509 certificates to be included in the default blacklist
+ keyring.
