Eric Dumazet fff3269907 tcp: reflect SYN queue_mapping into SYNACK packets ... While testing how linux behaves on SYNFLOOD attack on multiqueue device (ixgbe), I found that SYNACK messages were dropped at Qdisc level because we send them all on a single queue. Obvious choice is to reflect incoming SYN packet @queue_mapping to SYNACK packet. Under stress, my machine could only send 25.000 SYNACK per second (for 200.000 incoming SYN per second). NIC : ixgbe with 16 rx/tx queues. After patch, not a single SYNACK is dropped.
