Bug #8429

radvd/IPv6 broken in 2.4.3 when using a LAN bridge
0%
Description
Due to the fix for #6974 included in 2.4.3 (commits 1, 2, 3), radvd no longer works when using a bridge as the LAN interface due to bridges not actually having any media. Without radvd, IPv6 routes aren't sent to clients and IPv6 connectivity is non-existent (outside of link-local).
Sample logs:
Apr 3 19:20:09 radvd 53166 ioctl(SIOCGIFMEDIA) failed on bridge0: Invalid argument Apr 3 19:19:58 radvd 53166 ioctl(SIOCGIFMEDIA) failed on bridge0: Invalid argument Apr 3 19:19:48 radvd 53166 ioctl(SIOCGIFMEDIA) failed on bridge0: Invalid argument Apr 3 19:19:38 radvd 53166 ioctl(SIOCGIFMEDIA) failed on bridge0: Invalid argument Apr 3 19:19:28 radvd 53166 ioctl(SIOCGIFMEDIA) failed on bridge0: Invalid argument [...]
My setup, for reference (works without issue in 2.4.2):
WAN -> em0 LAN -> bridge0 (opt1 opt2; Enabled IPv6 auto linklocal for SLAAC) opt1 -> em1 opt2 -> ovpns1 (tap) net.link.bridge.pfil_member=0 net.link.bridge.pfil_bridge=1
Since this is a fairly major regression, is there any chance of the original fix being reverted and a patch release issued, with an updated fix for #6974 appearing in 2.4.4?

Agreed, I'm facing the same issue. Please fix this in the next Dev & Rel version. Thanks.

Same Problem:
RADVD regression on 2.4.3 / radvd can not run on bridge Interface anymore...

I'm seeing a similar issue, but I am using a USB ethernet device for the LAN connection:
ioctl(SIOCGIFMEDIA) failed on ue0: Invalid argument
I assume it is related to this bug.

I have the same issue with LAN bridged over 3 ethernet interfaces. The following error is logged every 16 seconds:

Should be fixed with radvd-2.17_5. Please check with the next 2.4.4 snapshot.
Sorry for the breakage.

setup bridge from LAN, OPT1 and OPT2
setup stateless RA on LAN
connected to vswitch which is used by LAN
obtained address from pfsense
pinged LAN interface successfully

This is still happening with 2.4.4 when using ue0 (USB ethernet) as the LAN interface.

Hello,
this problem still persists. PRTG Syslog is being spammed with:
Source Message Hostname Timestamp (Device) Severity Tag Facility
15.06.2020 21:54:39 192.168.1.1 (SIOCGIFMEDIA) failed on ue0: Invalid argument radvd[93562]: 06-15 21:54:39 3 ioctl 3
every 10secs
What to do to remove/fix this?
Thanks in advance.
