SubjectRe: [PATCH 00/27] security, efi: Add kernel lockdown
From
Date
Hi David,

From the man page:

> Only validly signed modules may be loaded.
> .P
> Only validly signed binaries may be kexec'd.
> .P
> Only validly signed device firmware may be loaded.

fw_get_filesystem_firmware() calls kernel_read_file_from_path() to
read the firmware, which calls into the security hooks. Is there
another place that validates the firmware signatures.  I'm not seeing
which patch requires firmware to be signed?

Mimi
