[vpp-dev] No traffic passed, Congestion Drop bug? #vpp_stability #nat44
The setup is a machine running VPP 19.01, configured using NAT44, with two physical interfaces. One interface is inside, other one is outside. The unit was translating and passing traffic just fine, and then all of a sudden stopped passing anything through the outside interface. Any packet which hits it is immediately counted as a Congestion Drop. Doing a packet trace shows that the packet is sent to the worker handoff, then Congestion Drop increases. There is hardly any traffic passing through it right now, but any packet which does hit is dropped due to congestion. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] Help with two interfaces accessing outside network
Sorry for not being clear. Each of the interfaces is connected to a different network (ISP). The scenario is of dual WAN. One ISP is providing static address and other is providing DHCP. wan1 is receiving DHCP. If I ONLY have: ip route add 0.0.0.0/0 via 172.78.10.158 wan0 then I am able to ping from wan0 If I ONLY have: ip route add 0.0.0.0/0 via wan1 then I am able to ping from wan1 ping works from one interface or the other but not both. So, I am using this to setup dual WAN scenario where if one ISP is down, I can move the outbound connections via wan1 and vise versa. Thanks!

[vpp-dev] VPP 19.08 RC2 milestone is complete!
Hi all, I have created the v19.08-rc2 tag on stable/1908 and verified that 19.08-rc2 build artifacts are on packagecloud. VPP 19.08 Release Milestone RC2 is complete! As a reminder, the VPP 19.08 Release is next Wednesday August 21, 2019. https://wiki.fd.io/view/Projects/vpp/Release_Plans/Release_Plan_19.08#Release_Milestones The stable/1908 is accepting the critical bugfixes in the run-up to the release. Per the standard process, all bug fixes to stable branches should follow the best practices: All bug fixes must be double-committed to the release throttle as well as to the master branch Commit first to the release throttle, then "git cherry-pick" into master (or the other way, if you find it easier to ensure that the fix ends up in both branches) Manual merges may be required, depending on the degree of divergence between throttle and master All bug fixes need to have a Jira ticket Please put Jira IDs into the commit messages. Please use the same Jira ID for both the stable branch and master. --a -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] Question about libmemif API
Hi, I'm working on using libmemif in OVS. https://patchwork.ozlabs.org/patch/1140858/ While using the API, one question I have is, when I call err = memif_rx_burst(dev->handle, qid, dev->rx_bufs, NETDEV_MAX_BURST, ); There are 'recv' number of packets are at dev->rx_bufs, do I have to copy the packet buffer immediately to my master side? For example, I received 32 packets from memif_rx_burst, and I might process these packets in different order. Once done, is there an API to free each specific packet buffer back to memif buffer pool? Now the memif_refill_queue() can only specify number of buffers to refill, not which buffer. Thanks William -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] Help with two interfaces accessing outside network
I am assuming wan1 is also connected to same network as wan0, is that correct? Curious, what is your use case for wanting to have two interface connected to same network?

[vpp-dev] issue with vlib_thread_init
Hi all, I am using VPP version 19.04. I recently migrated to this VPP version from an older version and I am facing some issues during VPP startup. I have a plugin which I initialize using VLIB_INIT_FUNCTION. During the init, I use 'vlib_thread_main->n_threads' to fetch the number of workers and use this count to initialize different vectors in my plugin. I believe that this 'vlib_thread_main' is initialized during 'vlib_thread_init'. I have configured 4 workers in my startup.conf. However, sometimes, during the startup, in my plugin init, the value of 'vlib_thread_main->n_threads' appears to be 0. In fact, the entire vlib_thread_main is uninitialized. This happens some times, thus causing crash in my plugin. Has anyone else seen this issue? Regards, Siddarth -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] Help with two interfaces accessing outside network
Your VPP configs look fine. I can only guess at general network issues. My first guess would be that the DHCP process did not complete, yet. For my second guess, this: vpp# ping 8.8.8.8 source wan1 means take the source address from wan1, but this: ip route add 0.0.0.0/0 via 172.78.10.158 wan0 still routes the packet via wan0. Maybe the upstream peer does uRPF. /neale -Message d'origine- De : au nom de carlito nueno Date : mardi 13 août 2019 à 22:55 À : "vpp-dev@lists.fd.io" Objet : [vpp-dev] Help with two interfaces accessing outside network Hi all, I am trying to setup two WAN interfaces where each of them can access to the outside world at the same time. So far I have: set int state wan0 up set int state wan1 up set int ip address wan0 172.78.10.155/29 set dhcp client intfc wan1 hostname test-wans ip route add 0.0.0.0/0 via 172.78.10.158 wan0 vpp# ping 8.8.8.8 source wan0 vpp# ping 8.8.8.8 source wan1 I am unable to ping via wan1 Any advice?

Re: [vpp-dev] ipsec packets fragmented post encryption
Hi Sam, Please upgrade to at least 19.04. a lot of work went into IPSec for this release. /neale De : au nom de "Caffeine Coder via Lists.Fd.Io" Répondre à : "caffeine.co...@yahoo.com" Date : mercredi 14 août 2019 à 00:16 À : Vpp-dev Cc : "vpp-dev@lists.fd.io" Objet : [vpp-dev] ipsec packets fragmented post encryption Hi, I am on 18.10 and trying to enable reassembly and fragmentation. It is working fine for vxlan and vxlan-gpe tunnels but IPSec it is not. We set physical interface MTU to be 1500 and IPSEC interface MTU to 1350 to give room for encryption. The issue we are seeing is packets are getting fragmented sent out after encryption and causing traffic is getting dropped. Is there any different way to enable fragmentation and then encryption each fragment on 18.10. Thanks in advance. Sam -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
