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.
