Greetings, I would like to know where (in the kernel) UDP packets are dropped. I looked at udp_usrreq.c but is overwhelming for the 1st time. Is it possible to use DTrace to locate where the packets are being dropped? or is there a tool similar to 'dropwatch' which can tell me where in the kernel my packets are getting dropped? On Linux, I used dropwatch and they were dropped packets were at udp_queue_rcv_skb(). Thanks!
