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.

config SECURITY
        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.

config SECURITY_NETWORK
        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_CAPABILITIES
        bool "Default Linux Capabilities"
        depends on SECURITY
        help
          This enables the "default" Linux capabilities functionality.
          If you are unsure how to answer this question, answer Y.

config SECURITY_FILE_CAPABILITIES
        bool "File POSIX Capabilities (EXPERIMENTAL)"
        depends on (SECURITY=n || SECURITY_CAPABILITIES!=n) && EXPERIMENTAL
        default n
        help
          This enables filesystem capabilities, allowing you to give
          binaries a subset of root's powers without using setuid 0.

          If in doubt, answer N.

config SECURITY_ROOTPLUG
        bool "Root Plug Support"
        depends on USB=y && 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.
          
          If you are unsure how to answer this question, answer N.
