New Revision: 258718
URL: http://svnweb.freebsd.org/changeset/base/258718

Log:
  jail_v0.ip_number was always in host byte order.  This was handled
  in one of the many layers of indirection and shims through stable/7
  in jail_handle_ips().  When it was cleaned up and unified through
  kern_jail() for 8.x, the byte order swap was lost.
  
  This only matters for ancient binaries that call jail(2) themselves
  internally.
