Wolfgang Grandegger 7b6856a029 can: provide library functions for skb allocation ... This patch makes the private functions alloc_can_skb() and alloc_can_err_skb() of the at91_can driver public and adapts all drivers to use these. While making the patch I realized, that the skb's are *not* setup consistently. It's now done as shown below: skb->protocol = htons(ETH_P_CAN); skb->pkt_type = PACKET_BROADCAST; skb->ip_summed = CHECKSUM_UNNECESSARY; *cf = (struct can_frame *)skb_put(skb, sizeof(struct can_frame)); memset(*cf, 0, sizeof(struct can_frame)); The frame is zeroed out to avoid uninitialized data to be passed to user space. Some drivers or library code did not set "pkt_type" or "ip_summed". Also, "__constant_htons()" should not be used for runtime invocations, as pointed out by David Miller.
