Dear Developers of pktgen, After the recent updates of pktgen I was finally able to compile the code but I get 2 critical errors when I try to use pktgen. First: I testet the newest pktgen code from git on a virtual Machine using EVE-NG and a physical Computer with an Intel i9 and 2 1G Nics. On both I installed and compiled everything as stated in the dokumentation, but when using pktgen, I only get a Segment Fault. I doesnt matter if i try using a blank command like: sudo ./path/to/pktgen or if I use more statements like: sudo ./path/to/pktgen -l 0-1 – -P -m 1.0. I only get following error message: EAL: Detected CPU lcores: 6 EAL: Detected NUMA nodes: 1 EAL: Detected shared linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'PA' EAL: Probe PCI driver: net_virtio (1af4:1000) device: 0000:00:03.0 (socket -1) eth_virtio_pci_init(): Failed to init PCI device EAL: Requested device 0000:00:03.0 cannot be used EAL: Probe PCI driver: net_virtio (1af4:1000) device: 0000:00:04.0 (socket -1) EAL: Probe PCI driver: net_virtio (1af4:1000) device: 0000:00:05.0 (socket -1) TELEMETRY: No legacy callbacks, legacy socket not created Total memory used = 0 KB Port DevName Index NUMA PCI Information Src MAC Promiscuous ====== Pktgen got a Segment Fault Obtained 7 stack frames. ./Pktgen-DPDK/builddir/app/pktgen(+0x25e83) [0x5857c4580e83] /lib/x86_64-linux-gnu/libc.so.6(+0x42990) [0x746baa642990] ./Pktgen-DPDK/builddir/app/pktgen(+0x99a7) [0x5857c45649a7] ./Pktgen-DPDK/builddir/app/pktgen(+0xa793) [0x5857c4565793] /lib/x86_64-linux-gnu/libc.so.6(+0x28150) [0x746baa628150] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0x89) [0x746baa628209] ./Pktgen-DPDK/builddir/app/pktgen(+0xb025) [0x5857c4566025] The error occurs on both machines running ubuntu-23.10. I have a testsetup in EVE-NG with the exact same specs, but running ubuntu-22.04. With dpdk 22.11.5 and pktgen 22.04.1 I was able to run pktgen with the statements mentioned above. But whatever I do in the pktgen command line, I am not able to generate traffic. My final goal is using pktgen to read pcap files and use them to generate traffic. The machine with ubuntu-22.04 opens my imix.pcap file when using -s 0:imix.pcap, but again I am not able to generate any traffic. If I try to open the pcap file on one of the ubuntu-23.10 machines, I get following error: EAL: Detected CPU lcores: 6 EAL: Detected NUMA nodes: 1 EAL: Detected shared linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'PA' EAL: Probe PCI driver: net_virtio (1af4:1000) device: 0000:00:03.0 (socket -1) eth_virtio_pci_init(): Failed to init PCI device EAL: Requested device 0000:00:03.0 cannot be used EAL: Probe PCI driver: net_virtio (1af4:1000) device: 0000:00:04.0 (socket -1) EAL: Probe PCI driver: net_virtio (1af4:1000) device: 0000:00:05.0 (socket -1) TELEMETRY: No legacy callbacks, legacy socket not created EAL: Error - exiting with code: 1 Cause: pktgen_pcap_open: rte_zmalloc_socket() failed for pcap_info_t structure Can someone help me to figure out whats wrong? I really start to question myself. If you need more data let me know. Thank you in advance Sincerely Florian Düsing
