Hi, I'm trying to test out DNA mode on the pfdnacluster_master example program to see if it works, and I'm getting a floating point exception when the program starts. I compiled the ixgbe DNA driver, as well as copied the .a from the libs/ directory into lib/ to get the architecture-specific file. I loaded the ixgbe driver as follows:
insmod pf_ring.ko insmod ./ixgbe.ko RSS=1,1,1,1 ./pfdnacluster_master -i data -c 1 -n 2 -a Capturing from data Using PF_RING v.5.5.2 Hashing packets per-IP Address Floating point exception gdb shows the following: Hashing packets per-IP Address Program received signal SIGFPE, Arithmetic exception. 0x0000000000410fa9 in dna_cluster_enable () (gdb) backtrace #0 0x0000000000410fa9 in dna_cluster_enable () #1 0x0000000000407d4b in main () Lastly, dmesg shows: [PF_RING] Welcome to PF_RING 5.5.2 ($Revision: $) (C) 2004-13 ntop.org [PF_RING] registered /proc/net/pf_ring/ NET: Registered protocol family 27 [PF_RING] Min # ring slots 4096 [PF_RING] Slot version 14 [PF_RING] Capture TX Yes [RX+TX] [PF_RING] Transparent Mode 0 [PF_RING] IP Defragment No [PF_RING] Initialized correctly Intel(R) 10 Gigabit PCI Express Network Driver - version 3.10.16-DNA Copyright (c) 1999-2012 Intel Corporation. ixgbe 0000:0e:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 ixgbe 0000:0e:00.0: setting latency timer to 64 ixgbe: Receive-Side Scaling (RSS) set to 1 ixgbe 0000:0e:00.0: irq 37 for MSI/MSI-X ixgbe 0000:0e:00.0: irq 38 for MSI/MSI-X [DNA] Hardware filtering rule not supported (no 82599) ixgbe 0000:0e:00.0: (PCI Express:2.5GT/s:Width x8) 00:00:50:87:7e:e0 ixgbe 0000:0e:00.0: data: MAC: 1, PHY: 0, PBA No: 010613-031 ixgbe 0000:0e:00.0: data: Enabled Features: RxQ: 1 TxQ: 1 LRO ixgbe 0000:0e:00.0: data: Intel(R) 10 Gigabit Network Connection ixgbe 0000:0e:00.1: PCI INT B -> GSI 17 (level, low) -> IRQ 17 ixgbe 0000:0e:00.1: setting latency timer to 64 ixgbe: Receive-Side Scaling (RSS) set to 1 udev: renamed network interface dna0 to data [DNA] MTU resize at runtime is not YET supported on DNA ixgbe 0000:0e:00.1: irq 39 for MSI/MSI-X ixgbe 0000:0e:00.1: irq 40 for MSI/MSI-X ADDRCONF(NETDEV_UP): data: link is not ready [DNA] Hardware filtering rule not supported (no 82599) ixgbe 0000:0e:00.1: (PCI Express:2.5GT/s:Width x8) 00:00:50:87:7e:e1 ixgbe 0000:0e:00.1: rtm10g: MAC: 1, PHY: 0, PBA No: 010613-031 ixgbe 0000:0e:00.1: rtm10g: Enabled Features: RxQ: 1 TxQ: 1 LRO ixgbe 0000:0e:00.1: rtm10g: Intel(R) 10 Gigabit Network Connection udev: renamed network interface dna0 to rtm10g [DNA] MTU resize at runtime is not YET supported on DNA ADDRCONF(NETDEV_UP): rtm10g: link is not ready ixgbe 0000:0e:00.0: data: NIC Link is Up 10 Gbps, Flow Control: None ADDRCONF(NETDEV_CHANGE): data: link becomes ready ixgbe 0000:0e:00.1: rtm10g: NIC Link is Up 10 Gbps, Flow Control: None ADDRCONF(NETDEV_CHANGE): rtm10g: link becomes ready rtm10g: no IPv6 routers present data: no IPv6 routers present device data entered promiscuous mode pfdnacluster_ma[1768] trap divide error ip:410fa9 sp:7fff78cd7950 error:0 in pfdnacluster_master[400000+50000] Anyone know what could be wrong? I'm running this on a 64-bit 6-core Xeon E5645 processor.
