# SPDX-License-Identifier: GPL-2.0-only config SECURITY_SMACK bool "Simplified Mandatory Access Control Kernel Support" depends on NET depends on INET depends on SECURITY select NETLABEL select SECURITY_NETWORK default n help This selects the Simplified Mandatory Access Control Kernel. Smack is useful for sensitivity, integrity, and a variety of other mandatory security schemes. If you are unsure how to answer this question, answer N. 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. config SECURITY_SMACK_NETFILTER bool "Packet marking using secmarks for netfilter" depends on SECURITY_SMACK depends on NETWORK_SECMARK depends on NETFILTER default n help This enables security marking of network packets using Smack labels. If you are unsure how to answer this question, answer N. 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.
