Subject: [41/61] Enforce module signatures if the kernel is locked down
|
|
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/commit?id=a9643aef5a6c576f32a97053b4024638943044ca

|
|
If the kernel is locked down, require that all modules have valid
|
|
signatures that we can verify.
