Title: "ip -6 addr flush" flushes much more than just the addresses Status in linux package in Ubuntu: Incomplete Bug description: root@testv6-tester:~# ls /proc/sys/net/ipv*/conf/ /proc/sys/net/ipv4/conf/: all default eth0 lo sit0 /proc/sys/net/ipv6/conf/: all default eth0 lo sit0 root@testv6-tester:~# ip addr flush dev eth0 root@testv6-tester:~# ls /proc/sys/net/ipv*/conf/ /proc/sys/net/ipv4/conf/: all default eth0 lo sit0 /proc/sys/net/ipv6/conf/: all default lo sit0 This results in no IPv6 connectivity on the interface and no obvious way to get it back to working condition other than destroying and recreating the interface (usually by rebooting). I reproduced this on the stable 12.04 kernel (3.2.0-26-generic) as well as 12.10 (3.5.0-3-generic). This is currently breaking ipv6 connectivity for some dual-stack setups in debian-installer though only for Ubuntu 12.10 (because the flush call was ipv4-specific in 12.04). I'll workaround the issue in d-i, but this bug should really be looked into.
