Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Hi Steven Shared memory is setup correctly. I am seeing following errors. System on which there is no crash it doesn't support 1G hugepages. So I have to use 2M hugepages with following config for VPP. (1) host vpp# show error CountNode Reason vpp# show error CountNode Reason 5vhost-user-inputmmap failure 5 ethernet-input l3 mac mismatch vpp# (2) Host VPP config unix { nodaemon log /var/log/vpp/vpp.log full-coredump cli-listen /run/vpp/cli.sock gid vpp } api-trace { on } api-segment { gid vpp } dpdk { no-pci huge-dir /dev/hugepages socket-mem 16,0 } (3) Container vpp# show error CountNode Reason 5ip4-glean ARP requests sent vpp# (4) Container VPP config unix { nodaemon log /var/log/vpp/vpp.log full-coredump cli-listen /run/vpp/cli.sock gid vpp } api-trace { on } api-segment { gid vpp } dpdk { no-pci huge-dir /dev/hugepages socket-mem 8,0 vdev virtio_user0,path=/var/run/usvhost1 } Thanks.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Ravi, I supposed you already checked the obvious that the vhost connection is established and shared memory has at least 1 region in show vhost. For traffic issue, use show error to see why packets are dropping. trace add vhost-user-input and show trace to see if vhost is getting the packet.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Ravi, I only have an SSE machine (Ivy Bridge) and DPDK is using ring mempool as far as I can tell from gdb. You are using AVX2 which I don't have one to try it to see whether Octeontx mempool is the default mempool for AVX2. What do you put in dpdk in the host startup.conf? What is the output for show dpdk version? Steven On 6/5/18, 1:40 PM, "vpp-dev@lists.fd.io on behalf of Ravi Kerur" wrote: Hi Damjan, I am not intentional using it.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Ravi, Do this 1. Run VPP native vhost-user in the host. Turn on debug "debug vhost-user on". 2. Bring up the container with the vdev virtio_user commands that you have as before 3. show vhost-user in the host and verify that it has a shared memory region. If not, the connection has a problem. Collect the show vhost-user and debug vhost-user and send them to me and stop. If yes, proceed with step 4. 4. type "trace vhost-user-input 100" in the host 5. clear error, and clear interfaces in the host and the container. 6. do the ping from the container. 7. Collect show error, show trace, show interface, and show vhost-user in the host. Collect show error and show interface in the container. Put output in github and provide a link to view. There is no need to send a large file. Steven On 6/4/18, 5:50 PM, "Ravi Kerur" wrote: Hi Steven, Thanks for your help.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Hi Steven, Thanks for your help. I am using vhost-user client (VPP in container) and vhost-user server (VPP in host). I thought it should work. create vhost socket /var/run/vpp/sock3.sock server (On host) create vhost socket /var/run/usvhost1 (On container) Can you please point me to a document which shows how to create VPP virtio_user interfaces or static configuration in /etc/vpp/startup.conf? I have used following declarations in /etc/vpp/startup.conf # vdev virtio_user0,path=/var/run/vpp/sock3.sock,mac=52:54:00:00:04:01 # vdev virtio_user1,path=/var/run/vpp/sock4.sock,mac=52:54:00:00:04:02 but it doesn't work.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Ravi, VPP only supports vhost-user in the device mode. In your example, the host, in device mode, and the container also in device mode do not make a happy couple. You need one of them, either the host or container, running in driver mode using the dpdk vdev virtio_user command in startup.conf. So you need something like this (host) VPP native vhost-user - (container) VPP DPDK vdev virtio_user -- or -- (host) VPP DPDK vdev virtio_user (container) VPP native vhost-user Steven On 6/4/18, 3:27 PM, "Ravi Kerur" wrote: Hi Steven Though crash is not happening anymore, there is still an issue with Rx and Tx.

show interface and look for the counter and count columns for the corresponding interface. Steven On 5/31/18, 1:28 PM, "Ravi Kerur" wrote: Hi Steven, You made my day, thank you. I didn't realize different dpdk versions (vpp -- 18.02.1 and testpmd -- from latest git repo (probably 18.05) could be the cause of the problem, I still dont understand why it should as virtio/vhost messages are meant to setup tx/rx rings correctly? I downloaded dpdk 18.02.1 stable release and at least vpp doesn't crash now (for both vpp-native and dpdk vhost interfaces).

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Hi Steven, i have tested following scenarios and it basically is not clear why you think DPDK is the problem? Is it possible VPP and DPDK use different virtio versions? Following are the scenarios I have tested (1) testpmd/DPDK vhost-user (running on host) and testpmd/DPDK virito-user (in a container) -- can send and receive packets (2) VPP-native vhost-user (running on host) and testpmd/DPDK virtio-user (in a container) -- VPP crashes and it is in VPP code (3) VPP-DPDK vhost user (running on host) and testpmd/DPDK virtio-user (in a container) -- VPP crashes and in DPDK Thanks.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Ravi, I've proved my point -- there is a problem in the way that you invoke testpmd. The shared memory region that it passes to the device is not accessible from the device. I don't know what the correct options are that you need to use. This is really a question for dpdk. As a further exercise, you could remove VPP in the host and instead run testpmd in device mode using "--vdev net_vhost0,iface=/var/run/vpp/sock1.sock" option. I bet you testpmd in the host will crash in the same place. I hope you can find out the answer from dpdk and tell us about it.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Ravi, First and foremost, get rid of the feature-mask option. I don't know what 0x4040 does for you. If that does not help, try testing it with dpdk based vhost-user instead of VPP native vhost-user to make sure that they can work well with each other first. To use dpdk vhost-user, add a vdev command in the startup.conf for each vhost-user device that you have. dpdk { vdev net_vhost0,iface=/var/run/vpp/sock1.sock } dpdk based vhost-user interface is named VhostEthernet0, VhostEthernet1, etc. Make sure you use the right interface name to set the state to up. If dpdk based vhost-user does not work with testpmd either, it looks like some problem with the way that you invoke testpmd. If dpdk based vhost-user works well with the same testpmd device driver and not vpp native vhost-user, I can set up something similar to yours to look into it. The device driver, testpmd, is supposed to pass the shared memory region to VPP for TX/RX queues. It looks like VPP vhost-user might have run into a bump there with using the shared memory (txvq->avail). Steven PS. vhost-user is not an optimum interface for containers. You may want to look into using memif if you don't already know about it.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Steve, Thanks for inputs on debugs and gdb. I am using gdb on my development system to debug the issue. I would like to have reliable core generation on the system on which I don't have access to install gdb. I installed corekeeper and it still doesn't generate core. I am running vpp inside a VM (VirtualBox/vagrant), not sure if I need to set something inside vagrant config file. dpkg -l corekeeper Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version ArchitectureDescription +++--===-===-== ii corekeeper 1.6 amd64 enable core files and report crashes to the system Thanks.

Re: [vpp-dev] VPP Vnet crash with vhost-user interface
Ravi, I install corekeeper and the core file is kept in /var/crash. But why not use gdb to attach to the VPP process? To turn on VPP vhost-user debug, type "debug vhost-user on" at the VPP prompt.

The location of the coredump file depends on your system configuration. Please, check "cat /proc/sys/kernel/core_pattern" If you have systemd-coredump in the output of the above command, then likely the location of the coredump files is "/var/lib/systemd/coredump/" You can also change the location of where your system places the coredump files: echo '/PATH_TO_YOU_LOCATION/core_%e.%p' | sudo tee /proc/sys/kernel/core_pattern See if that helps... > > (2) How to enable debugs?

[vpp-dev] VPP Vnet crash with vhost-user interface
Hello, I have a VM(16.04.4 Ubuntu x86_64) with 2 cores and 4G RAM. I have installed VPP successfully on it. Later I have created vhost-user interfaces via create vhost socket /var/run/vpp/sock1.sock server create vhost socket /var/run/vpp/sock2.sock server set interface state VirtualEthernet0/0/0 up set interface state VirtualEthernet0/0/1 up set interface l2 bridge VirtualEthernet0/0/0 1 set interface l2 bridge VirtualEthernet0/0/1 1 I then run 'DPDK/testpmd' inside a container which will use virtio-user interfaces using the following command docker run -it --privileged -v /var/run/vpp/sock1.sock:/var/run/usvhost1 -v /var/run/vpp/sock2.sock:/var/run/usvhost2 -v /dev/hugepages:/dev/hugepages dpdk-app-testpmd ./bin/testpmd -c 0x3 -n 4 --log-level=9 -m 64 --no-pci --single-file-segments --vdev=virtio_user0,path=/var/run/usvhost1,mac=54:01:00:01:01:01 --vdev=virtio_user1,path=/var/run/usvhost2,mac=54:01:00:01:01:02 -- -i VPP Vnet crashes with following message May 27 11:44:00 localhost vnet[6818]: received signal SIGSEGV, PC 0x7fcca4620187, faulting address 0x7fcb317ac000 Questions: I have 'ulimit -c unlimited' and /etc/vpp/startup.conf has unix { nodaemon log /var/log/vpp/vpp.log full-coredump cli-listen /run/vpp/cli.sock gid vpp } But I couldn't locate corefile?
