Christoph Jaeger 46d2cfb192 packet: bail out of packet_snd() if L2 header creation fails ... Due to a misplaced parenthesis, the expression (unlikely(offset) < 0), which expands to (__builtin_expect(!!(offset), 0) < 0), never evaluates to true. Therefore, when sending packets with PF_PACKET/SOCK_DGRAM, packet_snd() does not abort as intended if the creation of the layer 2 header fails. Spotted by Coverity - CID 1259975 ("Operands don't affect result").
