As a follow-up to the discussion about CVE-2019-3701 I walked through the
can-gw code to add the support for handling CAN FD frames.

Patch 1/3 is still the CVE fix and can be omitted when a recent Linux tree
is used that is already patched.

Patch 2/3 and 3/3 introduce the CAN FD support.

The updated user space tool 'cangw' can be found in the 'cangwfd' branch of
my can-utils fork at https://github.com/hartkopp/can-utils .

Feedback and testing is welcome!

Oliver Hartkopp (3):
  can: gw: ensure DLC boundaries after CAN frame modification
  can: gw: use struct canfd_frame as internal data structure
  can: gw: add support for CAN FD frames
