Hi,
Smatch complains abbout 72961ecf84d67d6 "netfilter: nfnetlink_log: send
complete hardware header" which is net-next.
462 if (indev && skb->dev) {
^^^^^^^^
skb->dev can be NULL here.
463 struct nfulnl_msg_packet_hw phw;
464 int len = dev_parse_header(skb, phw.hw_addr);
465 if (len > 0) {
466 phw.hw_addrlen = htons(len);
467 NLA_PUT(inst->skb, NFULA_HWADDR, sizeof(phw), &phw);
468 }
469 }
470
471 if (indev && skb_mac_header_was_set(skb)) {
472 NLA_PUT_BE16(inst->skb, NFULA_HWTYPE, htons(skb->dev->type));
^^^^^^^^
It's dereferenced here.
473 NLA_PUT_BE16(inst->skb, NFULA_HWLEN,
474 htons(skb->dev->hard_header_len));
I'm not sure how you want to deal with this.
regards,
dan carpenter
