This code has suffered from broken core design and lack of developer attention. Broken security modules are too dangerous to leave around. It is time to remove this one.

config KEYS
|
|
bool "Enable access key retention support"
|
|
help
|
|
This option provides support for retaining authentication tokens and
|
|
access keys in the kernel.
|
|
|
|
It also includes provision of methods by which such keys might be
|
|
associated with a process so that network filesystems, encryption
|
|
support and the like can find them.
|
|
|
|
Furthermore, a special type of key is available that acts as keyring:
|
|
a searchable sequence of keys. Each process is equipped with access
|
|
to five standard keyrings: UID-specific, GID-specific, session,
|
|
process and thread.
|
|
|
|
If you are unsure as to whether this is required, answer N.

config KEYS_DEBUG_PROC_KEYS

bool "Enable the /proc/keys file by which keys may be viewed"
|
|
depends on KEYS
|
|
help
|
|
This option turns on support for the /proc/keys file - through which
|
|
can be listed all the keys on the system that are viewable by the
|
|
reading process.
|
|
|
|
The only keys included in the list are those that grant View
|
|
permission to the reading process whether or not it possesses them.
|
|
Note that LSM security checks are still performed, and may further
|
|
filter out keys that the current process is not authorised to view.
|
|
|
|
Only key attributes are listed here; key payloads are not included in
|
|
the resulting table.
|
|
|
|
If you are unsure as to whether this is required, answer N.

help
|
|
This allows you to choose different security modules to be

|
configured into your kernel.
|
|
|
|
If this option is not selected, the default Linux security
|
|
model will be used.

bool "Socket and Networking Security Hooks"
|

depends on SECURITY
|
|
help
|
|
This enables the socket and networking security hooks.
|
|
If enabled, a security module can use these hooks to
|
|
implement socket and networking access controls.
|
|
If you are unsure how to answer this question, answer N.

config SECURITY_NETWORK_XFRM

bool "XFRM (IPSec) Networking Security Hooks"
|
|
depends on XFRM && SECURITY_NETWORK
|
|
help
|
|
This enables the XFRM (IPSec) networking security hooks.
|
|
If enabled, a security module can use these hooks to
|
|
implement per-packet access controls based on labels
|
|
derived from IPSec policy. Non-IPSec communications are
|
|
designated as unlabelled, and only sockets authorized
|
|
to communicate unlabelled data can send without using
|
|
IPSec.
|
|
If you are unsure how to answer this question, answer N.

config SECURITY_ROOTPLUG

tristate "Root Plug Support"

depends on USB && SECURITY
|
|
help
|
|
This is a sample LSM module that should only be used as such.
|
|
It prevents any programs running with egid == 0 if a specific
|
|
USB device is not present in the system.
|
|
|
|
See <http://www.linuxjournal.com/article.php?sid=6279> for
|
|
more information about this module.
