  11           This selects the Simplified Mandatory Access Control Kernel.
  12           Smack is useful for sensitivity, integrity, and a variety
  13           of other mandatory security schemes.

  21           Enable the bring-up ("b") access mode in Smack rules.
  22           When access is granted by a rule with the "b" mode a
  23           message about the access requested is generated. The
  24           intention is that a process can be granted a wide set
  25           of access initially with the bringup mode set on the
  26           rules. The developer can use the information to
  27           identify which rules are necessary and what accesses
  28           may be inappropriate. The developer can reduce the
  29           access rule set once the behavior is well understood.
  30           This is a superior mechanism to the oft abused
  31           "permissive" mode of other systems.

  50           Sending a signal has been treated as a write operation to the
  51           receiving process. If this option is selected, the delivery
  52           will be an append operation instead. This makes it possible
  53           to differentiate between delivering a network packet and
  54           delivering a signal in the Smack rules.
