can: dev: Consolidate and unify state change handling

2018-11-20T18:05:47+00:00

commit bac78aabcfece0c493b2ad824c68fbdc20448cbc upstream.

The handling of can error states is different between platforms.
This is an attempt to correct that problem.

I've moved this handling into a generic function for changing the
error state. This ensures that error state changes are handled
the same way everywhere (where this function is used).

This new mechanism also adds reverse state transitioning in error
frames, i.e. the user will be notified through the socket interface
when the state goes down.

can: unify identifiers to ensure unique include processing

2014-05-19T07:38:24+00:00

Armin pointed me to the fact that the identifier which is used to ensure the
unique include processing in lunux/include/uapi/linux/can.h is CAN_H.
This clashed with his own source as includes from libraries and APIs should
use an underscore '_' at the identifier start.

This patch fixes the protection identifiers in all CAN relavant includes.

can: allow to change the device mtu for CAN FD capable devices

2014-03-07T08:18:23+00:00

The configuration for CAN FD depends on CAN_CTRLMODE_FD enabled in the driver
specific ctrlmode_supported capabilities.

The configuration can be done either with the 'fd { on | off }' option in the
'ip' tool from iproute2 or by setting the CAN netdevice MTU to CAN_MTU (16) or
to CANFD_MTU (72).

can: introduce the data bitrate configuration for CAN FD

2014-03-07T08:18:22+00:00

As CAN FD offers a second bitrate for the data section of the CAN frame the
infrastructure for storing and configuring this second bitrate is introduced.
Improved the readability of the if-statement by inserting some newlines.

can: add explicit copyrights to can's netlink header

2013-09-21T13:43:12+00:00

This file is copied to the source code of user space applications (in
this case can-utils) and so it makes sense to mention explicitly their
copyright.

These files are copied to the source code of user space applications (in

commit as these headers.

can: gw: add a per rule limitation of frame hops

2013-08-29T20:58:24+00:00

Usually the received CAN frames can be processed/routed as much as 'max_hops'
times (which is given at module load time of the can-gw module).
Introduce a new configuration option to reduce the number of possible hops
for a specific gateway rule to a value smaller then max_hops.

can: gw: indicate and count deleted frames due to misconfiguration

2013-01-26T15:59:02+00:00

Add a statistic counter to detect deleted frames due to misconfiguration with
a new read-only CGW_DELETED netlink attribute for the CAN gateway.

2013-01-26T15:59:01+00:00

Introduce new configuration flag CGW_FLAGS_CAN_IIF_TX_OK to configure if a
CAN sk_buff that has been routed with can-gw is allowed to be send back to
the originating CAN interface.
