Subject: [PATCH v2 0/5] Enable root to update the blacklist keyring

Hi,

This second patch series includes some minor fixes and remove the 4 fix
patches picked by David Howells.  This patch series can then be applied
on top of
https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=keys-fixes

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.

Previous patch series:
https://lore.kernel.org/lkml/20201120180426.922572-1-mic@digikod.net/

Regards,

Mickaël Salaün (5):
  certs: Make blacklist_vet_description() more strict
  certs: Factor out the blacklist hash creation
  certs: Check that builtin blacklist hashes are valid
  certs: Allow root user to append signed hashes to the blacklist
    keyring
  tools/certs: Add print-cert-tbs-hash.sh
