can: add the missing netlink get_xstats_size callback

2009-11-14T03:56:55+00:00

This patch adds the missing "get_xstats_size" callback for the netlink interface, which is required if "fill_xstats" is used, as pointed out by Patrick McHardy. Signed-off-by: Wolfgang Grandegger Signed-off-by: David S. Miller

can: fix WARN_ON dump in net/core/rtnetlink.c:rtmsg_ifinfo()

2009-11-08T08:45:48+00:00

On older kernels, e.g. 2.6.27, a WARN_ON dump in rtmsg_ifinfo() is thrown when the CAN device is registered due to insufficient skb space, as reported by various users. This patch adds the rtnl_link_ops "get_size" to fix the problem. I think this patch is required for more recent kernels as well, even if no WARN_ON dumps are triggered. Maybe we also need "get_xstats_size" for the CAN xstats. Signed-off-by: Wolfgang Grandegger Signed-off-by: David S. Miller

can: add can_free_echo_skb() for upcoming drivers

2009-09-04T09:16:14+00:00

This patch adds the function can_free_echo_skb to the CAN device interface to allow upcoming drivers to release echo skb's in case of error. Signed-off-by: Wolfgang Grandegger Signed-off-by: David S. Miller

drivers: Kill now superfluous ->last_rx stores

2009-09-03T06:07:36+00:00

The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Signed-off-by: Eric Dumazet Acked-by: Neil Horman Signed-off-by: David S. Miller

can: fix oops caused by wrong rtnl newlink usage

2009-08-13T23:33:01+00:00

For 'real' hardware CAN devices the netlink interface is used to set CAN specific communication parameters. Real CAN hardware can not be created with the ip tool ... The invocation of 'ip link add type can' lead to an oops as the standard rtnl newlink function was called: http://bugzilla.kernel.org/show_bug.cgi?id=13954 This patch adds a private newlink function for the CAN device driver interface that unconditionally returns -EOPNOTSUPP.

can: switch carrier on if device was stopped while in bus-off state

2009-07-20T19:28:30+00:00

This patch fixes a problem when a device is stopped while in the bus-off state. Then the carrier remains off forever. Signed-off-by: Kurt Van Dijck Signed-off-by: Wolfgang Grandegger Signed-off-by: David S. Miller

can: restart device even if dev_alloc_skb() fails

2009-07-20T19:28:29+00:00

If dev_alloc_skb() failed in can_restart(), the device was left behind in the bus-off state. This patch restarts the device nevertheless. Signed-off-by: Kurt Van Dijck Signed-off-by: Wolfgang Grandegger Signed-off-by: David S. Miller

can: some fixes and cleanups to the initial device driver interface

2009-06-01T09:53:33+00:00

This patch fixes a few errors sneaked into the initial version of the device driver interface. Signed-off-by: Wolfgang Grandegger Signed-off-by: David S. Miller

can: CAN Network device driver and Netlink interface

2009-05-18T22:41:41+00:00

The CAN network device driver interface provides a generic interface to setup, configure and monitor CAN network devices. It exports a set of common data structures and functions, which all real CAN network device drivers should use. Please have a look to the SJA1000 or MSCAN driver to understand how to use them. The name of the module is can-dev.ko. Furthermore, it adds a Netlink interface allowing to configure the CAN device using the program "ip" from the iproute2 utility suite.
