Hi, everyone I'm testing packet flooding test with old kernel version 2.6.30. My board experienced process starvation when injecting ICMP flood with hping3 tool. I modified softirq invocation routine to launch ksoftirqd instead of executing do_softirq and I limitted the speed of ethernet phy to accept below 10Mbps. It seems that the board can process flooding ICMP packets of 10Mbps, but the board cannot process against TCP/UDP packet flooding, the speed of processes become slow down. IPtabls of which rule is dropping all TCP/UDP packet does not improve the situation. How can I protect the TCP/UDP flooding in my environment. Thanks in advance.
