Hello YOSHIFUJI Hideaki / 吉藤英明,
The patch 6752c8db8e0c: "firewire net, ipv4 arp: Extend hardware
address and remove driver-level packet inspection." from Mar 25,
2013, leads to the following warning:
"drivers/firewire/net.c:278 fwnet_header_parse()
error: memcpy() 'haddr' too small (8 vs 16)"
drivers/firewire/net.c
276 static int fwnet_header_parse(const struct sk_buff *skb, unsigned char *haddr)
277 {
278 memcpy(haddr, skb->dev->dev_addr, FWNET_ALEN);
^^^^^^^^^^
We bumped this to 16 bytes and made the fwnet_header and fwnet_hwaddr
structs bigger. But according to Smatch this is still an 8 byte buffer
here. Either phw.hw_addr or sll->sll_addr.
The call tree would be:
-> packet_rcv()
-> dev_parse_header()
-> fwnet_header_parse()
279
280 return FWNET_ALEN;
281 }
282
regards,
dan carpenter
