Bug#859941: [systemd] systemd-networkd: bridge vlan: does not remove vlan 1
Package: systemd Version: 232-22 Severity: important When adding a port to a VLAN-enabled bridge VLAN 1 is not removed. That leads to information leakage from VLAN 1 to other VLANs and IPv6 misconfiguration (via RAdv). In my use case the other end is a VM whose interface is created by libvirt, but that does not seem to make a difference, so I use a veth device here.

I can't really comment on the bug report as such, but it doesn't look like it's a Debian specific issue. So it would be great if you can raise this upstream at https://github.com/systemd/systemd/issues -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? signature.asc Description: OpenPGP digital signature ___ Pkg-systemd-maintainers mailing list Pkg-systemd-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-systemd-maintainers
