2009-01-06can: omit unneeded skb_clone() callsOliver Hartkopp
The AF_CAN core delivered always cloned sk_buffs to the AF_CAN protocols, although this was _only_ needed by the can-raw protocol. With this (additionally documented) change, the AF_CAN core calls the callback functions of the registered AF_CAN protocols with the original (uncloned) sk_buff pointer and let's the can-raw protocol do the skb_clone() itself which omits all unneeded skb_clone() calls for other AF_CAN protocols.

2008-12-03can: Fix CAN_(EFF|RTR)_FLAG handling in can_filterOliver Hartkopp
Due to a wrong safety check in af_can.c it was not possible to filter for SFF frames with a specific CAN identifier without getting the same selected CAN identifier from a received EFF frame also. This fix has a minimum (but user visible) impact on the CAN filter API and therefore the CAN version is set to a new date. Indeed the 'old' API is still working as-is. But when now setting CAN_(EFF|RTR)_FLAG in can_filter.can_mask you might get less traffic than before - but still the stuff that you expected to get for your defined filter ... Thanks to Kurt Van Dijck for pointing at this issue and for the review. Signed-off-by: Oliver Hartkopp <oliver@hartkopp.net> Acked-by: Kurt Van Dijck <kurt.van.dijck@eia.be> Signed-off-by: David S.

2008-01-28[CAN]: Fix plain integer definitions in userspace header.Oliver Hartkopp
This patch fixes the use of plain integers instead of __u32 in a struct that is visible from kernel space and user space. Thanks to Sam Ravnborg for pointing out the wrong plain int usage.

2008-01-28[CAN]: Add PF_CAN core moduleOliver Hartkopp
This patch adds the CAN core functionality but no protocols or drivers. No protocol implementations are included here. They come as separate patches.
