Bug Description
On my office desktop machine I observe that it accumulates temporary IPv6 addresses over time, even though all except one are marked as deprecated already.
E.g. right now my IP list looks like this:
2: eno1: <BROADCAST,
inet6 2620:101:
valid_lft 594471sec preferred_lft 75471sec
inet6 2620:101:
valid_lft 508673sec preferred_lft 0sec
inet6 2620:101:
valid_lft 422875sec preferred_lft 0sec
inet6 2620:101:
valid_lft 337078sec preferred_lft 0sec
inet6 2620:101:
valid_lft 251280sec preferred_lft 0sec
inet6 2620:101:
valid_lft 165483sec preferred_lft 0sec
inet6 2620:101:
valid_lft 79685sec preferred_lft 0sec
inet6 2620:101:
valid_lft 2591996sec preferred_lft 604796sec
inet6 fe80::baca:
valid_lft forever preferred_lft forever
Once I reboot the interface has only the one IP addressed based on MAC address plus one temporary address.
I verified manually via 'netstat -anp' that no active network connections or listening sockets remain on the interfaces which are marked as deprecated.
I think the deprecated addresses should be removed once no socket is any longer using the address.
