This selects NSA Security-Enhanced Linux (SELinux).
|
|
You will also need a policy configuration and a labeled filesystem.
|
|
If you are unsure how to answer this question, answer N.

help
|
|
This option adds a kernel parameter 'selinux', which allows SELinux
|
|
to be disabled at boot. If this option is selected, SELinux
|
|
functionality can be disabled with selinux=0 on the kernel
|
|
command line. The purpose of this option is to allow a single
|
|
kernel image to be distributed with SELinux built in, but not
|
|
necessarily enabled.
|

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

help
|
|
This enables the development support option of NSA SELinux,
|
|
which is useful for experimenting with SELinux and developing
|
|
policies. If unsure, say Y. With this option enabled, the
|
|
kernel will start in permissive mode (log everything, deny nothing)
|
|
unless you specify enforcing=1 on the kernel command line. You
|
|
can interactively toggle the kernel between enforcing mode and
|
|
permissive mode (if permitted by the policy) via
|
|
/sys/fs/selinux/enforce.

help
|

This option collects access vector cache statistics to
|

/sys/fs/selinux/avc/cache_stats, which may be monitored via
|
|
tools such as avcstat.

help
|
|
This option sets the number of buckets used in the sidtab hashtable
|
|
to 2^SECURITY_SELINUX_SIDTAB_HASH_BITS buckets. The number of hash
|
|
collisions may be viewed at /sys/fs/selinux/ss/sidtab_hash_stats. If
|
|
chain lengths are high (e.g. > 20) then selecting a higher value here
|
|
will ensure that lookups times are short and stable.

int "NSA SELinux SID to context string translation cache size"

default 256
|
|
help
|
|
This option defines the size of the internal SID -> context string
|
|
cache, which improves the performance of context to string
|
|
conversion. Setting this option to 0 disables the cache completely.
|
|
|
|
If unsure, keep the default value.
