Commit d43de6c780 ("akcipher: Move the RSA DER encoding check to
the crypto layer") removed the Kconfig option PUBLIC_KEY_ALGO_RSA,
but forgot to remove a 'select' to this option in the definition of
INTEGRITY_ASYMMETRIC_KEYS.
Let's remove the select, as it's ineffective now.

This option enables the integrity subsystem, which is comprised
|
|
of a number of different components including the Integrity
|
|
Measurement Architecture (IMA), Extended Verification Module
|
|
(EVM), IMA-appraisal extension, digital signature verification
|
|
extension and audit measurement log support.
|
|
|
|
Each of these components can be enabled/disabled separately.
|
|
Refer to the individual components for additional details.

help
|
|
This option enables digital signature verification support
|
|
using multiple keyrings. It defines separate keyrings for each
|
|
of the different use cases - evm, ima, and modules.
|
|
Different keyrings improves search performance, but also allow
|
|
to "lock" certain keyring to prevent adding new keys.
|
|
This is useful for evm and module keyrings, when keys are
|
|
usually only added from initramfs.

help
|

In addition to enabling integrity auditing support, this
|
|
option adds a kernel parameter 'integrity_audit', which
|
|
controls the level of integrity auditing messages.
|
|
0 - basic integrity auditing messages (default)
|
|
1 - additional integrity auditing messages
|
|
|
|
Additional informational integrity auditing messages would
|
|
be enabled by specifying 'integrity_audit=1' on the kernel
|
|
command line.
