|

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",

certificate as described in Documentation/admin-guide/module-signing.rst

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.

|
|
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.

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.

those keys are not blacklisted and are vouched for by a key built

into the kernel or already in the secondary trusted keyring.

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.

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.

If set, this allows revocation certificates to be stored in the

be checked to see if it matches such a certificate.
