Modified files:
sys/net bpf.c
Log:
Introduce support for Mandatory Access Control and extensible
kernel access control.
Instrument BPF so that MAC labels are properly maintained on BPF
descriptors. MAC framework entry points are invoked at BPF
instantiation and allocation, permitting the MAC framework to
derive the BPF descriptor label from the credential authorizing
the device open. Also enter the MAC framework to label mbufs
created using the BPF device.
