Subject: potential bug in bnep_net_set_mc_list()
Date: Sat, 19 Jun 2010 01:09:17 +0200 [thread overview]
Message-ID: <20100618230916.GA5467@bicker> (raw)
This is from ff6e2163f28a: "net: convert multiple drivers to use
netdev_for_each_mc_addr, part7"
net/bluetooth/bnep/netdev.c
101 i = 0;
102 netdev_for_each_mc_addr(ha, dev) {
103 if (i == BNEP_MAX_MULTICAST_FILTERS)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
104 break;
105 memcpy(__skb_put(skb, ETH_ALEN), ha->addr, ETH_ALEN);
106 memcpy(__skb_put(skb, ETH_ALEN), ha->addr, ETH_ALEN);
107 }
"i" is never incremented here so the check is always false.
regards,
dan carpenter
