Subject: [PATCH] KEYS: Make use of platform keyring for module signature
|
|
verify
|
|
|
|
This patch completes commit 278311e417be ("kexec, KEYS: Make use of
|
|
platform keyring for signature verify") which, while adding the
|
|
platform keyring for bzImage verification, neglected to also add
|
|
this keyring for module verification.
|
|
|
|
As such, kernel modules signed with keys from the MokList variable
|
|
were not successfully verified.
