From: Ludovic Courtès <ludovic.courtes@inria.fr>
Previously, we would get a fishy 127.0.0.1/0 interface:
$ ip a show dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet 127.0.0.1/0 scope global lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
With this change, we get nothing but the "/8" version:
$ ip a show dev lo
1: lo: <LOOPBACK,MULTICAST,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope global lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
Reported by Yann Dupont <Yann.Dupont@univ-nantes.fr>.
* gnu/services/base.scm (assert-valid-address): Remove special cases for
127.0.0.1 and ::1.
(%loopback-static-networking): Add "/8".
