Subject: [PATCH v3 00/10] Enable root to update the blacklist keyring
This third patch series includes back three fix patches taken from the first
series (and cherry-picked from David Howells's tree [1]), and one cosmetic fix
from Alex Shi which helps avoid future conflicts. I also added some Acked-by
and improved comments. As requested, this series is based on v5.11-rc3.
The goal of these patches is to add a new configuration option to enable the
root user to load signed keys in the blacklist keyring. This keyring is useful
to "untrust" certificates or files. Enabling to safely update this keyring
without recompiling the kernel makes it more usable.
