+menu "Certificates for signature checking"
+ 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/module-signing.txt
+ bool "Provide system-wide ring of trusted keys"
+ depends on KEYS
+ 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.
+ string "Additional X.509 keys for default system 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.
