Hi All, I have applied changes to add thenew helper: bpf_get_current_pidns_info using bpf-next branch. Let me know if what you think. From 932f55d885bf34443bb73ec4b24f9dd4b95b64c7 Mon Sep 17

The example is made by two parts, a eBPF program that consumes elements from a FIFO queue and prints them in the screen and a user space application that inserts new elements into the queue each time

Bpf queue implements a LIFO/FIFO data containers for ebpf programs. It allows to push an element to the queue by using the update operation and to pop an element from the queue by using the lookup

Bpf queue map is a new kind of map that provides a LIFO/FIFO queue implementation. In some applications, like a SNAT, it is necessary to keep track of a pool of free elemenets, network ports in this

I am not sure, it is more an example than a test, real tests are already in tools/testing/selftests/bpf/test_maps.c. Maybe we can rename it to queue_map_sample or something similar, or remove it if

I have no any preference over that, will do that way. I missed that, will do. I realized that I totally missed the support for preallocating elements. In v2 I implemented a per cpu free list based

I think that I need kprobe, map_update_elem and map_delete_elem are defined in kernel space. Thank You, Raffaele <sunny@...> ha scritto: -- ________________________________ Raffaele

You likely want uprobes if your function is defined in userspace, not kprobes (which are for functions defined in kernel space). relevant link:

Hello, I have tried to use kprobe but it fails when I try to attach a kprobe on that function with this error: raise Exception("Failed to attach BPF to kprobe") I use

Hi, We will have a BPF hackfest in Berlin on September 26th and 27th, 10am to 5pm in the Kinvolk office. This is just before the All Systems Go! conference (https://all-systems-go.io/), so there will

bpf tracepoints have been removed from recent linux so the you need to use kprobe to trace update/delete. typical map_update_elem and map_delete_elem first argument is 'struct bpf_map *map', you can

Hello everybody, I was looking for a similar mechanism, I need to trace an event on map update/delete, I have tried with tracepoint but I can recover only the file descriptor of map and I need the map
