    sbin/mountd          mountd.c 
  Log:
  The introduction of IPv6 support from NetBSD's mountd invalidated
  a number of assumptions related to the parsing of options in
  /etc/exports, and missed a few necessary new error checks.
  
  The main problems related to netmasks: an IPv6 network address
  missing a netmask would result in the filesystem being exported to
  the whole IPv6 world, non-continuous netmasks would be made continuous
  without any warnings, and nothing prevented you specifying an IPv4
  mask with an IPv6 address.
  
  This change addresses these issues. As a side-effect we now store
  netmasks in sockaddr structs (this matches the kernel interface,
  and is closer to the way it used to be). Add a flag OP_HAVEMASK to
  keep track of whether or not we have successfully got a mask from
  any source. Replace some mask-related helper functions with versions
  that use the sockaddr-based masks.
  
  Also tidy up get_net() and fix the code that interprets IPv4 partial
  networks such as "127.1" as network rather than host addresses.
  Properly zero out some structures that were ending up partially
  containing junk from the stack, fix a few formatting issues, and
  add a comment noting some assumptions about export arguments.
