Re: [ovs-dev] [PATCH] vxlan: Fix for the packet loop issue in vxlan

Thanks for your feedback. This means that recent kernel changes might have fixed the issue. I will see if there is any generic solution for the issue. On Thu, Jun 14, 2018 at 8:09 AM, Pravin Shelar wrote: > On Wed, Jun 13, 2018 at 5:16 AM, Neelakantam Gaddam > wrote: > > It should be Qdisc's

Re: [ovs-dev] [PATCH] vxlan: Fix for the packet loop issue in vxlan

It should be Qdisc's busylock in dev_queue_xmit function. I have seen the issue in kernel version is 3.10.87 vanilla. On Wed, Jun 13, 2018 at 12:21 PM, Pravin Shelar wrote: > On Tue, Jun 12, 2018 at 10:58 PM, Neelakantam Gaddam > wrote: > > Hi Pravin, > > > > I have seen the below crash. > >

Hi Pravin, The below configuration is causing the spinlock recursion issue. I am able to see the issue with below configuration. ovs-vsctl add-br br0 ovs-vsctl add-bond br0 bond0 p1p1 p1p2 ovs-vsctl set port bond0 lacp=active bond_mode=balance-tcp ifconfig br0 100.0.0.1 up ovs-vsctl

[ovs-dev] [PATCH] vxlan: Fix for the packet loop issue in vxlan

This patch fixes the kernel soft lockup issue with vxlan configuration where the tunneled packet is sent on the same bridge where vxlan port is attched to. It detects the loop in vxlan xmit functionb and drops if loop is detected. Signed-off-by: Neelakantam Gaddam ---
