I noticed two fa= cts after the upgrade from 13.2-STABLE to 14.0-STABLE: 1. Messages like "arp: 00:aa:bb:cc:dd:ee trying to modify permanent entry f= or w.x.y.z on vlanQ" disappeared from Syslog even though the net.link.ether.inet.log_arp_permanent_modify parameter is set to 1. 2. When traffic from an IP address protected by a static ARP entry is recei= ved from a spoofed host with the same IP address that violates this policy, the= ARP entry for that IP address looks a bit strange: ? (w.x.y.z) at aa:bb:cc:dd:00:11 on vlan2 expires in -1708011502 seconds [vlan], but when the bogus traffic stops, the entry looks as expected ? (w.x.y.z.) at aa:bb:cc:dd:00:11 on vlan2 permanent [vlan]. --=20 You are receiving this mail because: You are the assignee for the bug.=
