      net: drop dst before queueing fragments · 97599dc7
      Eric Dumazet 提交于
      Commit 4a94445c (net: Use ip_route_input_noref() in input path)
      added a bug in IP defragmentation handling, as non refcounted
      dst could escape an RCU protected section.
      
      Commit 64f3b9e2 (net: ip_expire() must revalidate route) fixed
      the case of timeouts, but not the general problem.
      
      Tom Parkin noticed crashes in UDP stack and provided a patch,
      but further analysis permitted us to pinpoint the root cause.
      
      Before queueing a packet into a frag list, we must drop its dst,
      as this dst has limited lifetime (RCU protected)
      
      When/if a packet is finally reassembled, we use the dst of the very
      last skb, still protected by RCU and valid, as the dst of the
      reassembled packet.
      
      Use same logic in IPv6, as there is no need to hold dst references.

      ipv6: statically link register_inet6addr_notifier() · f88c91dd

      Tomas reported the following build error:
      
      net/built-in.o: In function `ieee80211_unregister_hw':
      (.text+0x10f0e1): undefined reference to `unregister_inet6addr_notifier'
      net/built-in.o: In function `ieee80211_register_hw':
      (.text+0x10f610): undefined reference to `register_inet6addr_notifier'
      make: *** [vmlinux] Error 1
      
      when built IPv6 as a module.
      
      So we have to statically link these symbols.
