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.
