I've been testing it for 5 days now with moderate load (>50mbps, 3kpps) including all sorts of junk traffic to invalid destinations, and there doesn't seem to be a leak now. yesterday i cvsuped to RELENG_8 and tried the patch as i could see the problem with lltable was fixed by the patch but some of other stuff was broken, i saw some new messages: Mar 31 00:33:04 i1 kernel: ip_dn_ctl dummynet: compat option 60 Mar 31 00:33:04 i1 kernel: ip_dummynet_compat setting compatibility with FreeBSD 8 Mar 31 01:49:10 i1 kernel: in_cksum_skip: out of data by 38505 Mar 31 09:02:46 i1 kernel: ipfw: ouch!, skip past end of rules, denying packet and some ip-addresses in vlanes was not working so i rebooted to the old kernel it may be somthing with ipfw in RELENG_8 maybe i could test the patch with RELENG_8_0 but list time i tried it there was a mpd error like "ifa_add_loopback_route: insertion failed" i tried it on march 12 and don't kown is it fixed.. -- Evgenii V Davidov
