Bug#1106276: systemd-networkd: regression when neighbour advertisements are received without the router flag

[Philip Stewart]

Package: src:systemd
Version: 257.5-2
Severity: important
Tags: fixed-upstream

Hello,

A regression in networkd, introduced in v256, drops neighbour
discovery configurations if neighbour advertisements are received
without the router flag, but a host can send router advertisements
without acting as a router, e.g. a host may advertise itself as a DNS
resolver.

The fix has already been backported into the v257-stable branch
upstream and therefore should be in v257.6, whenever it is released:

Best wishes,
