Yes Dave, we are initiating a loopback delete from our application. But I don't find anything suspicious in this code path, my guess is may be the hash was already corrupted. Regarding my question of thread_barrier lock, I was refering to the current patch in unix_cli_file_add() where we are mod

Sorry to interject with my questions. 1. Is Linux-cp alternative to tapv2 interfaces? 2. If ping plug-in is disabled, what’s the alternative to test ping? Thanks and sorry again for abrupt and novice questions. On Thu, Jun 17, 2021 at 5:59 PM Mike Beattie wrote: > On Wed, Jun 16, 2021 at 09:14

This is a different code path which might need the same sort of fix. Looks likely that you sent a VL_API_DELETE_LOOPBACK message. AFAICT that message is not marked thread-safe, so it will be processed on thread 0 with the thread barrier held. D. From: vpp-dev@lists.fd.io On Behalf

Hi Dave, This hash node key corruption I observed while debugging a VPP crash due to node_by_name hash access which seems to be corrupted. So I thought the unix-cli-local node might be the root cause, but after the patch also we saw the crash again. The bt looks like below. * Frame 00: /li

Hi Damjan, We need dpdk, the reason being that packets from the NICs ( pollmode ) need to come inside our packet processing sw ( GTPU). So we wanted to use dpdk for the same. Now we wanted to know the pod in which vpp is running in non-previleged mode. Now we have questions i) is it possible ? ii
