Move certificate handling out of the kernel/ directory and into a certs/ directory to get all the weird stuff in one place and move the generated signing keys into this directory. Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-by: David Woodhouse <David.Woodhouse@intel.com>

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

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.

|
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.
