https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273539 Bug ID: 273539 Summary: VLAN issue after upgrading from stable/13 to main or stable/14 - kernel without COMPAT_FREEBSD12 Product: Base System Version: 14.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: herbert@gojira.at After updating from stable/13 to (main and later to) stable/14 net/mpd5 only connects to my ISP (VDSL with VLAN) if I enable "options COMPAT_FREEBSD12" in my kernel. Without I get only: Aug 30 15:08:06 gw mpd[59876]: [L1] PPPoE connection timeout after 9 seconds Aug 30 15:08:06 gw mpd[59876]: [L1] Link: DOWN event Aug 30 15:08:06 gw mpd[59876]: [L1] LCP: Down event Aug 30 15:08:06 gw mpd[59876]: [L1] Link: reconnection attempt 1 in 7 secon= ds Aug 30 15:08:14 gw mpd[59876]: [L1] Link: reconnection attempt 1 Aug 30 15:08:14 gw mpd[59876]: [L1] PPPoE: Connecting to '' Aug 30 15:08:23 gw mpd[59876]: [L1] PPPoE connection timeout after 9 seconds Aug 30 15:08:23 gw mpd[59876]: [L1] Link: DOWN event Aug 30 15:08:23 gw mpd[59876]: [L1] LCP: Down event [..] Without "COMPAT_FREEBSD12" vlanproto =3D 0x0000. If I run "ifconfig vlan31 vlanproto 802.1q" mpd5 works. According to ifconfig(8) 802.1q is the default vlanproto. Maybe this commit is related: commit afbb64f1d85b7d8c2938031c3567946b5d10da4f Author: Alexander V. Chernikov Date: Sun Apr 11 17:47:03 2021 +0100 Fix vlan creation for the older ifconfig(8) binaries. Reported by: allanjude MFC after: immediately ? To reproduce: build and run the following kernel: include GENERIC ident TEST nooptions COMPAT_FREEBSD12 stable/13: # ifconfig vlan99 create =3D=3D> vlanproto: 0x0000 # ifconfig vlan99 vlan 99 vlandev igb0 =3D=3D> vlanproto: 802.1q # ifconfig vlan99 destroy # ifconfig vlan99 create vlan 99 vlandev igb0 =3D=3D> vlanproto: 802.1q On stable/14 or main: # ifconfig vlan99 create =3D=3D> vlanproto 0x0000 # ifconfig vlan99 vlan 99 vlandev igb0 =3D=3D> vlanproto 0x0000 # ifconfig vlan99 create vlan 99 vlandev igb0 =3D=3D> vlanproto: 802.1q I guess that's why the following lines in my /etc/rc.conf no longer work on stable/14 or main. cloned_interfaces=3D"vlan99" ifconfig_vlan99=3D"vlan 99 vlandev igb0" I have to replace the ifconfig line with: ifconfig_vlan99=3D"vlan 99 vlandev igb0 vlanproto 802.1q" It also works if I remove the following lines in sys/net/if_vlan.c: 1110 #ifdef COMPAT_FREEBSD12 1113 #endif 2265 #ifdef COMPAT_FREEBSD12 2268 #endif --=20 You are receiving this mail because: You are the assignee for the bug.=
