      net: ipv6: Remove addresses for failures with strict DAD · 85b51b12
      Mike Manning authored
      If DAD fails with accept_dad set to 2, global addresses and host routes
      are incorrectly left in place. Even though disable_ipv6 is set,
      contrary to documentation, the addresses are not dynamically deleted
      from the interface. It is only on a subsequent link down/up that these
      are removed. The fix is not only to set the disable_ipv6 flag, but
      also to call addrconf_ifdown(), which is the action to carry out when
      disabling IPv6. This results in the addresses and routes being deleted
      immediately. The DAD failure for the LL addr is determined as before
      via netlink, or by the absence of the LL addr (which also previously
      would have had to be checked for in case of an intervening link down
      and up). As the call to addrconf_ifdown() requires an rtnl lock, the
      logic to disable IPv6 when DAD fails is moved to addrconf_dad_work().
      
      Previous behavior:
      
      root@vm1:/# sysctl net.ipv6.conf.eth3.accept_dad=2
      net.ipv6.conf.eth3.accept_dad = 2
      root@vm1:/# ip -6 addr add 2000::10/64 dev eth3
      root@vm1:/# ip link set up eth3
      root@vm1:/# ip -6 addr show dev eth3
      5: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
          inet6 2000::10/64 scope global
             valid_lft forever preferred_lft forever
          inet6 fe80::5054:ff:fe43:dd5a/64 scope link tentative dadfailed
             valid_lft forever preferred_lft forever
      root@vm1:/# ip -6 route show dev eth3
      2000::/64  proto kernel  metric 256
      fe80::/64  proto kernel  metric 256
      root@vm1:/# ip link set down eth3
      root@vm1:/# ip link set up eth3
      root@vm1:/# ip -6 addr show dev eth3
      root@vm1:/# ip -6 route show dev eth3
      root@vm1:/#
      
      New behavior:
      
      root@vm1:/# sysctl net.ipv6.conf.eth3.accept_dad=2
      net.ipv6.conf.eth3.accept_dad = 2
      root@vm1:/# ip -6 addr add 2000::10/64 dev eth3
      root@vm1:/# ip link set up eth3
      root@vm1:/# ip -6 addr show dev eth3
      root@vm1:/# ip -6 route show dev eth3
      root@vm1:/#
