Re: [vpp-dev] Q) Is it a possible acl-plugin race condtion?

API and CLI are executed under the worker barrier by default in VPP, only the VPP main thread runs, and workers are stopped. For an API/CLI to be executed concurrently with workers, it must be explicitly marked as such (mp_safe attribute). It does not seem to be the case for ACL, so it should be

[vpp-dev] Python VPP_API_DIR

Hoi, I am starting to work on a few APIs and noticed that the vpp_papi module's method find_api_dir promises that it will include VPP_API_DIR first, if specified in the environment. It doesn't actually do that. I wrote a changelist that prepends VPP_API_DIR if it exists. This is backwards compatib

Re: [vpp-dev] VPP crash while create ipip tunnel after a certain limit

To my knowledge there is no such ratio between heapsize and stackseg. based on your application needs you can tune these values. In your case as the number of ipip tunnels are more you may be required to increase stackseg size to accommodate the counters for those tunnel interfaces. Thanks and Re

Re: [vpp-dev] Wireguard api - incorrect key lengh issue

Hoi Petr, I think that the keys in the wireguard plugin are represented as bytestream, and your 44 character string probably refers to its base64 representation. Try sending the raw key (32 bytes). As an aside, I thought I'd ask ChatGPT this question, because I thought it was a fun puzzle. Pim:

Hi Chinmaya Aggarwal, I can see the "vec_resize_allocate_memory" api in the above stack and you are telling that after 7k tunnels this issue is seen. I suspect this issue could be due to memory exhaust in the system. Can you please increase heapsize and statseg size in startup.conf file and check

I'm no expert in LACP so maybe someone can jump in to confirm whether it looks good on VPP side, but as we're receiving LACP packets and VPP seems to be happy, I wonder if the issue could be VPP failing to send LACP packets back to the switch? Eg. because the NIC eat them up for some reason (sec

Hoi, VPP does not run on that board, because the soc does not enumerate its DPDK enabled interfaces on the PCIe bus, but rather has a custom bus, which VPP is not integrated with. Incidentally, I did get VPP itself to run but without DPDK (or AVF or etc) interfaces; and its basic functionality (ie

Hi, I think the 1st thing to try would be whether you can reproduce it with a debug build. The backtrace you have is not usable unfortunately. The easiest should be to build debug binaries: ~# make rebuild ~# ./build-root/install-vpp_debug-native/vpp/bin/vpp -c /etc/vpp/startup.conf Best Ben >
