This can reveal some IP (and MAC) addresses on the local networks and the frequency of the communication (ARP timeouts). This can be undesirable in some situations. >How-To-Repeat: Jail a user and issue arp -an. >Fix: It would be very good to have an option, similar to security.bsd.unprivileged_read_msgbuf to disable this kind of behaviour. >Release-Note: >Audit-Trail: >Unformatted:
