Hi, I'm running Ubuntu 16.04 on my VM with vmxnet3 as the NIC. I have successfully installed DPDK and managed to run a few sample apps. However when I tried pktgen the kernel threw a SIGSEGV without me doing anything yet.
$ sudo .app/x86_64-native-linuxapp-gcc/pktgen Pktgen:/> ====== Pktgen got a Segment Fault Obtained 11 stack frames. app/x86_64-native-linuxapp-gcc/pktgen() [0x468ba5] /lib/x86_64-linux-gnu/libc.so.6(+0x354b0) [0x7f1e618de4b0] app/x86_64-native-linuxapp-gcc/pktgen() [0x6c7c70] app/x86_64-native-linuxapp-gcc/pktgen(rte_eth_stats_get+0x79) [0x4a3fe9] app/x86_64-native-linuxapp-gcc/pktgen(pktgen_process_stats+0xa9) [0x46f0f9] app/x86_64-native-linuxapp-gcc/pktgen(rte_timer_manage+0x526) [0x48ca96] app/x86_64-native-linuxapp-gcc/pktgen(cli_start+0x26d) [0x71276d] app/x86_64-native-linuxapp-gcc/pktgen(pktgen_cli_start+0xb) [0x4509bb] app/x86_64-native-linuxapp-gcc/pktgen(main+0x7a6) [0x447b86] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0) [0x7f1e618c9830] app/x86_64-native-linuxapp-gcc/pktgen(_start+0x29) [0x44a639] # gdb .app/x86_64-native-linuxapp-gcc/pktgen Pktgen:/> Thread 1 "pktgen" received signal SIGSEGV, Segmentation fault. 0x00000000006c7c70 in vmxnet3_dev_stats_get () I tried using older versions of DPDK and pktgen but nothing worked so far. Is it a problem on my end? Like, the way I set up the NICs in my VM? Or is it a bug? BR, Long.
