Package: systemd
Version: 247.3-3
Severity: normal
Tags: ipv6 upstream patch
Dear Maintainer,
After configuring IPv6 Proxy NDP addresses on a link, and not
receiving any errors, the addresses disappeared from the link during
the system startup process. Restarting systemd-networkd restored the
addresses to the link, and the system operated as expected.
After extensive debugging, it was determined that in some cases during
system startup, a NIC will temporarily lose its 'carrier' (link) status,
and when this happens any previously-configured Proxy NDP addresses
on the link are removed by the kernel networking stack. systemd-networkd
was aware of this state change, but did not re-add the Proxy NDP
addresses to the link.
This was reported and confirmed upstream here:
https://github.com/systemd/systemd/issues/18378
A patch was provided to upstream, and merged here:
https://github.com/systemd/systemd/pull/18494
The patch was also merged to the upstream 'stable' branch here:
https://github.com/systemd/systemd-stable/issues/89
