https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=238580 Bug ID: 238580 Summary: [PATCH] respect defines from 'sys/netinet/ip_carp.h' Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: egypcio@FreeBSD.org Created attachment 205076 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=205076&action=edit D20638.diff based on information from man pages like carp(4) and ifconfig(8), some inconstant values popped out while I troubleshooted a HA setup using CARP. - advskew was able to be changed to values higher than CARP_MAXSKEW; - CARP advertisements collected via tcpdump were still using (respecting) its limit; changing values on net.inet.carp.demotion does not increase advskew above the limit (expected, I think). root@fw1-lab:~ # uname -UKvm FreeBSD 13.0-CURRENT r348978 GENERIC amd64 1300031 1300031 root@fw1-lab:~ # ifconfig vlan3131 vhid 10 advskew 254 root@fw1-lab:~ # echo $? 0 root@fw1-lab:~ # ifconfig vlan3131 | grep carp carp: MASTER vhid 10 advbase 1 advskew 254 root@fw1-lab:~ # tcpdump -c 1 -n -v -i vlan3131 carp -T carp tcpdump: listening on vlan3131, link-type EN10MB (Ethernet), capture size 262144 bytes 15:56:59.299379 IP (tos 0xe0, ttl 255, id 0, offset 0, flags [DF], proto VRRP (112), length 56) 172.31.31.1 > 224.0.0.18: carp 172.31.31.1 > 224.0.0.18: CARPv2-advertise 36: vhid=10 advbase=1 advskew=240 authlen=7 counter=8688083474654986394 1 packet captured 1 packet received by filter 0 packets dropped by kernel -- You are receiving this mail because: You are the assignee for the bug.home | help
