[vpp-dev] Formatted elogs more than 20 bytes
1. I need to log some events with elog which requires more than 20 bytes, therefore I changed the vppinfra/vppinfra/elog.h file: u8 data[20]; --->> u8 data[52]; Then, I have build the VPP project and test elog. It has a little lower performance. But would it cause some bugs or runtime problems? 2. Why there is such 20 bytes limitation (or why event must be padded to 32 bytes)? ___ vpp-dev mailing list vpp-dev@lists.fd.io https://lists.fd.io/mailman/listinfo/vpp-dev
[vpp-dev] A Simple Configuration Sample for IPFIX test
Hi, I search through VPP website and mailing list, but I didn't find a simple configuration sample for IPFIX test. I wasn't able to understand the configuration from command description (for example in "*set ipfix exporter collector [port ] src [fib-id ] [path-mtu ] [template-interval ] [udp-checksum]*" what is the first IP address and what is the second one? or what is the fib-id?) Thanks in advance ___ vpp-dev mailing list vpp-dev@lists.fd.io https://lists.fd.io/mailman/listinfo/vpp-dev
[vpp-dev] plugin to filter packets
Hello, VPP developers. I can't understand how to write plugin to filter some packets and passing others. I need to hook on some feature graph, check every packet and remove matched. I bound required IP for interface, hooked arc "ip4-local" (it can also be "ip4-unicast") with my node "checker" and do not understand how to write node function. My node function work if I enable plugin for interface. If I use node with next nodes as created by extras/emacs/make-plugin.sh VLIB_REGISTER_NODE (checker_node) = { // ... .n_next_nodes = CHECKER_N_NEXT, .next_nodes = { [CHECKER_NEXT_DROP] = "error-drop", }, }; I do not understand how to pass buffer to further nodes on arc in node function - so all packets dropped because next[0] = 0; Also as I understand feature arc can have many features enabled and all packets will be processed by all nodes on arc, so I do not know which node on "ip4-local" or "ip4-unicast" arc will be after my node to pass buffer there. So I do not understand what to write in .next_nodes except "error-drop" to pass unfiltered packets to further processing. If I use .n_next_nodes = 0, all packets will pass to next node on feature arc, but how to drop matched buffers? The best solution I found is to use vlib_buffer_free() or code like this vlib_node_t* drop_node = vlib_get_node_by_name (vm, (u8 *)"error-drop"); vlib_frame_t* f = vlib_get_frame_to_node (vm, drop_node->index ); f->n_vectors = 1; u32* to_next = vlib_frame_vector_args( f ); to_next[0] = buffer_index; vlib_put_frame_to_node( vm, drop_node->index, f ); and remove matched buffer indexes from vlib_buffer_enqueue_to_next(). (I know vlib_get_node_by_name() can be moved out of loop - this is not important.) But this solution will break batch processing architecture of vpp and I think there is better way (this looks like hack). As I understand I just need to assign some index to next[0] which is nexts for vlib_buffer_enqueue_to_next (vm, node, from, nexts, frame->n_vectors) but I do not understand how to get it. Please help to write node function which will drop matched packets and pass to next node on arc unmatched. What do I need to write in .next_nodes of VLIB_REGISTER_NODE and how to drop matched buffers and pass others to next nodes on feature arc in node function.

Re: [vpp-dev] #vpp-dev : How does the ping works from vppctl when we have 2 entries for the same Dest Addr with different sw_if_index
Hello. Probably "show ip fib 107.243.21.113/32" will give a clue.
