    sys/net              rtsock.c 
  Log:
  Zero the un-used portions of the struct sockaddr data before sending
  it back to userspace, so it does not break bind(2) on raw sockets in jails.
  
  Currently some processes, like traceroute(8) construct a routing request
  to determine its source address based on the destination. This sockaddr
  data is fed directly to bind(2). When bind calls ifa_ifwithaddr(9) to
  make sure the address exists on the interface, the comparison will
  fail causing bind(2) to return EADDRNOTAVAIL if the data wasnt zero'ed
  before initialization.
