Subject[PATCH v2 0/3] KEYS: validate certificate trust with selected owner or builtin key
Date
Instead of allowing public keys, with certificates signed by any key on
the system trusted keyring, to be added to a trusted keyring, this patch
set further restricts the certificates to those signed by a particular key
or builtin keys on the system keyring.

This patch defines a new kernel parameter 'keys_ownerid={id: | builtin}'
to use specific key or any builtin key.

Changes to v1:
* key id matching code from asymmetric_type.c is reused in the patch

Thanks,
Dmitry


Dmitry Kasatkin (3):
KEYS: make key id matching as a dedicated function
KEYS: validate certificate trust only with selected owner key
KEYS: validate certificate trust only with builtin keys
