Hello Arvid Brodin,
The patch f266a683a480: "net/hsr: Better frame dispatch" from Jul 4,
2014, leads to the following static checker warning:
net/hsr/hsr_framereg.c:293 hsr_addr_subst_dest()
warn: this array is probably non-NULL. 'node_dst->MacAddressB'
net/hsr/hsr_framereg.c
286 node_dst = find_node_by_AddrA(&port->hsr->node_db, eth_hdr(skb)->h_dest);
287 if (!node_dst) {
288 WARN_ONCE(1, "%s: Unknown node\n", __func__);
289 return;
290 }
291 if (port->type != node_dst->AddrB_port)
292 return;
293 if (!node_dst->MacAddressB) {
^^^^^^^^^^^^^^^^^^^^^^
This test is never true. It could be deleted or replaced.
294 WARN_ONCE(1, "%s: No MacAddressB\n", __func__);
295 return;
296 }
297
regards,
dan carpenter
