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 all keys may be viewed"

depends on KEYS
|
|
help
|
|
This option turns on support for the /proc/keys file through which
|
|
all the keys on the system can be listed.
|
|
|
|
This option is a slight security risk in that it makes it possible
|
|
for anyone to see all the keys on the system. Normally the manager
|
|
pretends keys that are inaccessible to a process don't exist as far
|
|
as that process is concerned.

bool "Enable different security models"

depends on SYSFS
|
|
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.

If you are unsure how to answer this question, answer N.

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.

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.
