https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273304 Bug ID: 273304 Summary: Regression: if_vlan(4): Vlan interface's PCP (priority code point) got overwritten when sending packets with custom PCP Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: zlei@FreeBSD.org Spot this while testing function of PCP. Reported here in case someone else encounter the same issue. Steps to repeat: 1. Create vlan interface with vlanpcp 2. Send ICMP requests with custom PCP 3. Verify the vlan interface's vlanpcp, it should not be altered Snip to simplify the repeat: ``` # ifconfig epair create epair0a # ifconfig epair0a.10 create vlanpcp 7 inet 192.0.2.1/24 # jail -ic vnet persist 1 # ifconfig epair0b vnet 1 # jexec 1 ifconfig epair0b up # jexec 1 ifconfig epair0b.10 create inet 192.0.2.2/24 # ping -C1 -c1 -t1 -q 192.0.2.2 # ifconfig epair0a.10 | grep vlanpcp vlan: 10 vlanproto: 802.1q vlanpcp: 1 parent interface: epair0a ``` --=20 You are receiving this mail because: You are the assignee for the bug.=
