Hello, If candump -x is used to dump CAN bus traffic on an interface while a J1939 socket is sending multi-packet messages, then the DAT and CTL frames show up as RX instead of TX. This patch series sets to generated struct sk_buff the owning struct sock pointer so that the MSG_DONTROUTE flag can be set by recv functions. I'm not sure that j1939_session_skb_get is needed, I think that session->sk could be directly passed as can_skb_set_owner parameter. This patch is based on j1939_simple_txnext function which uses j1939_session_skb_get. I can provide an additional patch to remove the calls to j1939_session_skb_get function if you think they are not needed. Thank you, Devid Devid Antonio Filoni (2): can: j1939: make sure that sent DAT frames are marked as TX can: j1939: make sure that sent CTL frames are marked as TX net/can/j1939/transport.c | 69 ++++++++++++++++++++++++++++++++------- 1 file changed, 57 insertions(+), 12 deletions(-) -- 2.25.1
