7config KEYS
8 bool "Enable access key retention support"
9 help
10 This option provides support for retaining authentication tokens and
11 access keys in the kernel.
12
13 It also includes provision of methods by which such keys might be
14 associated with a process so that network filesystems, encryption
15 support and the like can find them.
16
17 Furthermore, a special type of key is available that acts as keyring:
18 a searchable sequence of keys. Each process is equipped with access
19 to five standard keyrings: UID-specific, GID-specific, session,
20 process and thread.
21
22 If you are unsure as to whether this is required, answer N.

24config KEYS_DEBUG_PROC_KEYS
25 bool "Enable the /proc/keys file by which all keys may be viewed"
26 depends on KEYS
27 help
28 This option turns on support for the /proc/keys file through which
29 all the keys on the system can be listed.
30
31 This option is a slight security risk in that it makes it possible
32 for anyone to see all the keys on the system. Normally the manager
33 pretends keys that are inaccessible to a process don't exist as far
34 as that process is concerned.

40 This allows you to choose different security modules to be
41 configured into your kernel.
42
43 If this option is not selected, the default Linux security
44 model will be used.

50 depends on SECURITY
51 help
52 This enables the socket and networking security hooks.
53 If enabled, a security module can use these hooks to
54 implement socket and networking access controls.

68 This is a sample LSM module that should only be used as such.
69 It prevents any programs running with egid == 0 if a specific
70 USB device is not present in the system.
