For a CAN-FD frame, though, there is an extra field: struct canfd_frame { canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */ __u8 len; /* frame payload length in byte (0 .. 64) */ __u8 flags; /* additional flags for CAN FD */ __u8 __res0 ... WebHowever, those RTR frames still use the DLC to indicate the length of the requested frame. As such, net_device_stats:rx_bytes should not be increased for the RTR frames.

WebThe function can_get_echo_skb() already returns the correct length, even for RTR frames (c.f. [1]). However, for historical reasons, the drivers do not use can_get_echo_skb()'s return value and instead, most of them store a temporary length (or dlc) in some local structure or array. Using the return value of can_get_echo_skb() solves the issue.
