The vlan id for my em0 interface is not reading properly after upgrading to
4.5.
Tcpdump shows some wild vid values in the traffic when using em0:
* This traffic should be on vlan2 (lan)
00:21:70:c5:3d:4f ff:ff:ff:ff:ff:ff 8100 64: 802.1Q vid 512 pri 0 arp
who-has 10.107.208.1 tell 10.107.208.50
* This traffic should be on vlan3 (egress vlan)
00:1e:be:fe:f3:05 ff:ff:ff:ff:ff:ff 8100 64: 802.1Q vid 768 pri 0 arp
who-has 98.196.101.152 tell 98.196.100.1
00:1e:be:fe:f3:05 ff:ff:ff:ff:ff:ff 8100 64: 802.1Q vid 768 pri 0 arp
who-has 98.196.88.115 tell 98.196.88.1
* This traffic should be on vlan4, it is correct:
00:02:b3:ed:68:89 01:00:5e:7f:ff:fa 8100 308: 802.1Q vid 4 pri 0
10.0.0.1.29275 > 239.255.255.250.1900: udp 262 [ttl 1]
00:02:b3:ed:68:89 01:00:5e:7f:ff:fa 8100 380: 802.1Q vid 4 pri 0
10.0.0.1.29275 > 239.255.255.250.1900: udp 334 [ttl 1]
It seems as though the vlan id is being multiplied by 256 for vlans 2 and 3.
When I use the gem0 interface on the same machine, things work:
* This traffic should be on vlan2 (lan), it is correct:
00:03:ba:04:b2:1d 00:50:8d:95:39:17 8100 110: 802.1Q vid 2 pri 0

* This traffic should be on vlan3 (egress vlan), it is correct:
00:1e:be:fe:f3:05 ff:ff:ff:ff:ff:ff 8100 64: 802.1Q vid 3 pri 0 arp who-has
98.194.104.216 tell 98.194.104.1

The em0 interface worked without an issue using 4.4 as did gem0.

Note that vlan2 does not have an ip because dhclient could not get one.
dhclient could also not verify one of the leases stored in the lease db.
I collected the information above using the following procedure:
1. configure hostname.if files to use the em0 interface
# cat hostname.em0
up media autoselect
# cat hostname.gem0
up media autoselect
# cat hostname.vlan2
inet 10.107.208.1 255.255.255.0 NONE vlan 2 vlandev em0
# cat hostname.vlan3
dhcp vlan 3 vlandev em0
# cat hostname.vlan4
inet 10.0.0.1 255.255.255.0 NONE vlan 4 vlandev em0
# cat hostname.vlan5
inet 10.180.16.1 255.255.255.0 NONE vlan 5 vlandev em0
2. Plug the em0 port on the openbsd host into the tagged port on the switch.
3. restart the host
4. dump some packets from the em0 interface and grab the ifconfig output
5. configure hostname.if files to use the gem0 interface
# cat hostname.em0
up media autoselect
# cat hostname.gem0
up media autoselect
# cat hostname.vlan2
inet 10.107.208.1 255.255.255.0 NONE vlan 2 vlandev gem0
# cat hostname.vlan3
dhcp vlan 3 vlandev gem0
# cat hostname.vlan4
inet 10.0.0.1 255.255.255.0 NONE vlan 4 vlandev gem0
# cat hostname.vlan5
inet 10.180.16.1 255.255.255.0 NONE vlan 5 vlandev gem0
6. Plug the gem0 port on the openbsd host into the tagged port on the
switch.
7. restart the host
8. dump some packets from the gem0 interface and grab the ifconfig output
This machine was first built using 4.4, then upgraded to 4.5 using the
console/boot from cdrom method. The files were upgraded using diff and
manual updates for the files listed in the upgrade instructions; packages
were updated from a mirror. The switch is a dell powerconnect 5324 and is
configured with one tagged port on all vlans (2,3,4,5) and all the other
ports assigned untagged to a single vlan.
The packages installed on the host are minimal:
# pkg_info
gettext-0.17p0 GNU gettext
igmpproxy-0.1-beta2 Multicast router utilizing IGMP forwarding
kermit-8.0.211 serial and network communications package
libiconv-1.12 character set conversion library
lsof-4.81p0 list information about open files
malo-firmware-1.4 Firmware binary images for malo driver
rsync-3.0.5 mirroring/synchronization over low bandwidth links
wget-1.11.4 retrieve files from the web via HTTP, HTTPS and FTP
The kernel is an unmodified generic 4.5 kernel; the 4.4 kernel was
unmodified as well.
The syctl.conf changes are nothing out of the ordinary:
