can: fix handling of unmodifiable configuration options

2016-06-03T15:30:37Z

[ Upstream commit bb208f144cf3f59d8f89a09a80efd04389718907 ] As described in 'can: m_can: tag current CAN FD controllers as non-ISO' (6cfda7fbebe) it is possible to define fixed configuration options by setting the according bit in 'ctrlmode' and clear it in 'ctrlmode_supported'. This leads to the incovenience that the fixed configuration bits can not be passed by netlink even when they have the correct values (e.g. non-ISO, FD). This patch fixes that issue and not only allows fixed set bit values to be set again but now requires(!) to provide these fixed values at configuration time. A valid CAN FD configuration consists of a nominal/arbitration bittiming, a data bittiming and a control mode with CAN_CTRLMODE_FD set - which is now enforced by a new can_validate() function. This fix additionally removed the inconsistency that was prohibiting the support of 'CANFD-only' controller drivers, like the RCar CAN FD. For this reason a new helper can_set_static_ctrlmode() has been introduced to provide a proper interface to handle static enabled CAN controller options.

can: unify identifiers to ensure unique include processing

2014-05-19T07:38:24Z

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

2014-03-07T08:18:23Z

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

2014-03-07T08:18:22Z

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. Signed-off-by: Oliver Hartkopp Acked-by: Stephane Grosjean Signed-off-by: Marc Kleine-Budde

linux-can-next-for-3.15-20140212 Marc Kleine-Budde says: ==================== this is a pull request of eight patches for net-next/master. Florian Vaussard contributed a series that merged the sja1000 of_platform into the platform driver. The of_platform driver is finally removed. Stephane Grosjean supplied a patch to allocate CANFD skbs. In a patch by Uwe Kleine-König another missing copyright information was added to a userspace header. And a patch by Yoann DI RUZZA that adds listen only mode to the at91_can driver. ==================== Signed-off-by: David S. Miller

can: add destructor for self generated skbs

2014-01-31T00:25:49Z

Self generated skbuffs in net/can/bcm.c are setting a skb->sk reference but no explicit destructor which is enforced since Linux 3.11 with commit 376c7311bdb6 (net: add a temporary sanity check in skb_orphan()). This patch adds some helper functions to make sure that a destructor is properly defined when a sock reference is assigned to a CAN related skb. To create an unshared skb owned by the original sock a common helper function has been introduced to replace open coded functions to create CAN echo skbs.
