  Modified files:
    libexec/tftpd        tftpd.c 
  o Reduce path names in RRQ and WRQ packets by:
      Reducing "/+./" strings to "/"
      Reducing "/[^/]+/../" to "/"
  o Don't send an OACK when the result of the [RW]RQ is an error.
  These changes allow tftpd to interact with pxelinux.bin from the syslinux
  Whilst the path reducing code doesn't properly handle situations where the
  path component before the "/../" is a symlink to (say) ".", I would suggest
  that it does the right thing in terms of the clients perception of what
  their path string actually represents.  This seems better than using
  realpath() and breaking environments where symlinks point outside of the
  directory hierarchy that tftpd is configured to allow.
