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.

can: add private data space for CAN sk_buffs

2013-01-26T15:59:01Z

The struct can_skb_priv is used to transport additional information along with the stored struct can(fd)_frame that can not be contained in existing struct sk_buff elements. can_skb_priv is located in the skb headroom, which does not touch the existing CAN sk_buff usage with skb->data and skb->len, so that even out-of-tree CAN drivers can be used without changes. Btw. out-of-tree CAN drivers without can_skb_priv in the sk_buff headroom would not support features based on can_skb_priv. The can_skb_priv->ifindex contains the first interface where the CAN frame appeared on the local host. Unfortunately skb->skb_iif can not be used as this value is overwritten in every netif_receive_skb() call. Signed-off-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde
