config SECURITY_SELINUX
bool "SELinux Support"
depends on SECURITY_NETWORK && AUDIT && NET && INET
select NETWORK_SECMARK
default n
help
This selects 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.
config SECURITY_SELINUX_BOOTPARAM
bool "SELinux boot parameter"
depends on SECURITY_SELINUX
default 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.
config SECURITY_SELINUX_DEVELOP
bool "SELinux Development Support"
depends on SECURITY_SELINUX
default y
help
This enables the development support option of 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.
config SECURITY_SELINUX_AVC_STATS
bool "SELinux AVC Statistics"
depends on SECURITY_SELINUX
default y
help
This option collects access vector cache statistics to
/sys/fs/selinux/avc/cache_stats, which may be monitored via
tools such as avcstat.
config SECURITY_SELINUX_SIDTAB_HASH_BITS
int "SELinux sidtab hashtable size"
depends on SECURITY_SELINUX
range 8 13
default 9
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.
config SECURITY_SELINUX_SID2STR_CACHE_SIZE
int "SELinux SID to context string translation cache size"
depends on SECURITY_SELINUX
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.
config SECURITY_SELINUX_DEBUG
bool "SELinux kernel debugging support"
depends on SECURITY_SELINUX
default n
help
This enables debugging code designed to help SELinux kernel
developers, unless you know what this does in the kernel code you
should leave this disabled.
To fine control the messages to be printed enable
CONFIG_DYNAMIC_DEBUG and see
Documentation/admin-guide/dynamic-debug-howto.rst for additional
information.
Example usage:
echo -n 'file "security/selinux/*" +p' > \
/proc/dynamic_debug/control
