In commitc9dca822c7("net-loopback: set lo dev initial state to UP"), linux started automatically bringing up the loopback device of a newly created namespace. However, an existing user script might reasonably have the following stanza when creating a new namespace -- and in fact at least tools/testing/selftests/net/fib_nexthops.sh in Linux's very own testsuite does: # set -e # ip netns add foo # ip -netns foo addr add 127.0.0.1/8 dev lo # ip -netns foo link set lo up # set +e This will now fail, because the kernel reasonably rejects "ip addr add" of a duplicate address. The described change of behavior therefore constitutes a breakage. Revert it.
