can: peak: fix bad memory access and free sequence

2016-12-08T14:59:52+00:00

Fix for bad memory access while disconnecting. netdev is freed before
private data free, and dev is accessed after freeing netdev.

This makes a slub problem, and it raise kernel oops with slub debugger
config.

can: peak: Add support for PCAN-USB X6 USB interface

2016-12-01T13:12:20+00:00

This adds support for PEAK-System PCAN-USB X6 USB to CAN interface.

The CAN FD adapter PCAN-USB X6 allows the connection of up to 6 CAN FD
or CAN networks to a computer via USB. The interface is installed in an
aluminum profile casing and is shipped in versions with D-Sub connectors
or M12 circular connectors.

The PCAN-USB X6 registers in the USB sub-system as if 3x PCAN-USB-Pro FD
adapters were plugged. So, this patch:

- updates the PEAK_USB entry of the corresponding Kconfig file
- defines and adds the device id. of the PCAN-USB X6 (0x0014) into the
  table of supported device ids
- defines and adds the new software structure implementing the PCAN-USB X6,
  which is obviously a clone of the software structure implementing the
  PCAN-USB Pro FD.

can: peak: Fix bittiming fields size in bits

2016-12-01T13:11:25+00:00

This fixes the bitimings fields ranges supported by all the CAN-FD USB
interfaces of the PEAK-System CAN-FD adapters.

Very first development versions of the IP core API defined smaller TSGEx
and SJW fields for both nominal and data bittimings records than the
production versions. This patch fixes them by enlarging their sizes to
the actual values:

field:           old size:    fixed size:
nominal TSGEG1   6            8
nominal TSGEG2   4            7
nominal SJW      4            7
data TSGEG1      4            5
data TSGEG2      3            4
data SJW         2            4

Note that this has no other consequences than offering larger choice to
bitrate encoding.

Several cases of overlapping changes, except the packet scheduler
conflicts which deal with the addition of the free list parameter
to qdisc_enqueue().
