It was already fixed in kernel/linux22/net/ipv6/addrconf.c:1.33.

I believe CONFIG_IPV6_MODERATE_DOUBLE_BIND and/or 
CONFIG_NET_MODERATE_REUSE are/is enabled.  

If so, it should have been fixed in our current tree.

  kernel/linux22/include/net/tcp.h:1.4
  kernel/linux22/net/ipv4/tcp_input.c:1.4
  kernel/linux22/net/ipv4/tcp_ipv4.c:1.22
  kernel/linux22/net/ipv6/tcp_ipv6.c::1.24

Please try it.


Note: Similar fix was applied to the linux24 tree.

  kernel/linux22/include/net/tcp.h:1.4
  kernel/linux22/net/ipv4/tcp_minisock.c:1.4
  kernel/linux22/net/ipv4/tcp_ipv4.c:1.46
  kernel/linux22/net/ipv6/tcp_ipv6.c::1.43


Sorry for the mess.
