https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277063 --- Comment #10 from Marek Zarychta --- The above patch doesn't fix the issue. There is still something wrong with timers and permanent entries expire after some time. -- You are receiving this mail because: You are the assignee for the bug.

Let's revert to rtsosck code until this feature gets properly implemented in netlink. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277063 --- Comment #7 from Marek Zarychta --- (In reply to Marek Zarychta from comment #6) >I confirm this regression, but it's not 100% reproducible. It should have been "It is 100% reproducible". After the takeover of the IP by a bogus host, the Syslog logs only a notification of ARP change: arp: w.x.y.z moved from aa:bb:cc:dd:00:11 to 00:aa:bb:cc:dd:ee on vlan0 -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277063 --- Comment #6 from Marek Zarychta --- Please let me put my two cents in. I confirm this regression, but it's not 100% reproducible. I noticed two facts 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 for 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 received 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]. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277063 --- Comment #5 from Kristof Provost --- (In reply to Apoorv Sachan from comment #3) Yes, absolutely! It's of course up to you how you approach this, but I'd be inclined to start with a test case, both because a reproduction case will make debugging easier, but also because adding the test too will ensure this doesn't regress later. Current test cases live in tests/sys/netinet/arp.sh Also, even if you only get the test case to work and don't solve the bug itself, please do post the test. That's at least half of the work already. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277063 --- Comment #4 from Apoorv Sachan --- I want to contribute to freeBSD in the networking domain, I have experience with l3-udp and tcp(beginner) and in l2 with ARP and bridging protocols. I would love to contribute to this, I would start debugging this by looking at the arp table design, and also check if the command line options while setting static entries are parsed correctly. -- You are receiving this mail because: You are the assignee for the bug.
