Hi, One note on CARP and VRRP moving forwards. I realize that this patch is = partly a CARP specific issue but a lot of people on a few mailing lists seem to = have assumed that VRRP is no longer under patent threat. According to the FreeBSD Foundation's lawyers there are two extant patent= s, due to expire in 2017, 3 years hence. = CISCO =E2=80=93 US6108300: Method and apparatus for transparently providi= ng a failover network device = IBM: US6148410: Fault tolerant recoverable TCP/IP connection router, Bas= key, Dillenberger, Goldszmidt, Hunt, Levy-Abegnoli, Nick,Schmidt, Novembe= r 14, 2000. = So let's not go assuming that VRRP is "free" just yet. As to updating our CARP to behave correctly, that's still on the table.
