keyutils-1.6
Introduction to keyutils
Keyutils is a set of utilities for managing the key retention
facility in the kernel, which can be used by filesystems, block
devices and more to gain and retain the authorization and
encryption keys required to perform secure operations.
This package is known to build and work properly using an LFS-8.4
platform.

Installation of keyutils
Install keyutils by running the
following commands:
make
To test the results, issue, as the root user:
sed -i '/find/s:/usr/bin/::' tests/Makefile &&
make -k test
Note that several tests will fail if certain uncommon kernel
options were not used when the kernel was built. These include
CONFIG_BIG_KEYS, CONFIG_KEY_DH_OPERATIONS, and CONFIG_CRYPTO_DH.
Now, as the root user:
make NO_ARLIB=1 install
Command Explanations
NO_ARLIB=1: This make flag
disables installing the static library.

Short Descriptions
|
keyctl
|
is to control the key management facility in various ways
using a variety of subcommands.
|
|
key.dns_resolver
|
is invoked by request-key on behalf
of the kernel when kernel services (such as NFS, CIFS and
AFS) need to perform a hostname lookup and the kernel
does not have the key cached. It is not ordinarily
intended to be called directly.
|
|
request-key
|
is invoked by the kernel when the kernel is asked for a
key that it doesn't have immediately available. The
kernel creates a temporary key and then calls out to this
program to instantiate it. It is not intended to be
called directly.
|
|
libkeyutils.so
|
contains the keyutils library API instantiation.
