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

config SECURITY_SMACK_BRINGUP
	bool "Reporting on access granted by Smack rules"
	depends on SECURITY_SMACK
	default n
	help
	  Enable the bring-up ("b") access mode in Smack rules.
	  When access is granted by a rule with the "b" mode a
	  message about the access requested is generated. The
	  intention is that a process can be granted a wide set
	  of access initially with the bringup mode set on the
	  rules. The developer can use the information to
	  identify which rules are necessary and what accesses
	  may be inappropriate. The developer can reduce the
	  access rule set once the behavior is well understood.
	  This is a superior mechanism to the oft abused
	  "permissive" mode of other systems.
	  If you are unsure how to answer this question, answer N.

	  This enables security marking of network packets using

config SECURITY_SMACK_APPEND_SIGNALS
	bool "Treat delivering signals as an append operation"
	depends on SECURITY_SMACK
	default n
	help
	  Sending a signal has been treated as a write operation to the
	  receiving process. If this option is selected, the delivery
	  will be an append operation instead. This makes it possible
	  to differentiate between delivering a network packet and
	  delivering a signal in the Smack rules.
	  If you are unsure how to answer this question, answer N.
