+CIPSOv4 Variables:
+
+cipso_cache_enable - BOOLEAN
+ If set, enable additions to and lookups from the CIPSO label mapping
+ cache. If unset, additions are ignored and lookups always result in a
+ miss. However, regardless of the setting the cache is still
+ invalidated when required when means you can safely toggle this on and
+ off and the cache will always be "safe".
+ Default: 1
+
+cipso_cache_bucket_size - INTEGER
+ The CIPSO label cache consists of a fixed size hash table with each
+ hash bucket containing a number of cache entries. This variable limits
+ the number of entries in each hash bucket; the larger the value the
+ more CIPSO label mappings that can be cached. When the number of
+ entries in a given hash bucket reaches this limit adding new entries
+ causes the oldest entry in the bucket to be removed to make room.
+ Default: 10
+
+cipso_rbm_optfmt - BOOLEAN
+ Enable the "Optimized Tag 1 Format" as defined in section 3.4.2.6 of
+ the CIPSO draft specification (see Documentation/netlabel for details).
+ This means that when set the CIPSO tag will be padded with empty
+ categories in order to make the packet data 32-bit aligned.
+ Default: 0
+
+cipso_rbm_structvalid - BOOLEAN
+ If set, do a very strict check of the CIPSO option when
+ ip_options_compile() is called. If unset, relax the checks done during
+ ip_options_compile(). Either way is "safe" as errors are caught else
+ where in the CIPSO processing code but setting this to 0 (False) should
+ result in less work (i.e. it should be faster) but could cause problems
+ with other implementations that require strict checking.
