Subject: [PATCH v1 0/9] Enable root to update the blacklist keyring

Hi,

This patch series mainly 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.

Regards,

Mickaël Salaün (9):
  certs: Fix blacklisted hexadecimal hash string check
  certs: Make blacklist_vet_description() more strict
  certs: Factor out the blacklist hash creation
  certs: Check that builtin blacklist hashes are valid
  PKCS#7: Fix missing include
  certs: Fix blacklist flag type confusion
  certs: Allow root user to append signed hashes to the blacklist
    keyring
  certs: Replace K{U,G}IDT_INIT() with GLOBAL_ROOT_{U,G}ID
  tools/certs: Add print-cert-tbs-hash.sh
