The integrity subsystem has lots of options and takes more than half of the security menu. This patch consolidates the options under "integrity", which are hidden if not enabled. This change does not affect existing configurations. Re-configuration is not needed. Changes v4: - no need to change "integrity subsystem" to menuconfig as options are hidden, when not enabled. (Mimi) - add INTEGRITY Kconfig help description Changes v3: - dependency to INTEGRITY removed when behind 'if INTEGRITY' Changes v2: - previous patch moved integrity out of the 'security' menu. This version keeps integrity as a security option (Mimi). Signed-off-by: Dmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>

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.

|

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.
