2020-12-03bpf: samples: Do not touch RLIMIT_MEMLOCKRoman Gushchin1-6/+0
Since bpf is not using rlimit memlock for the memory accounting and control, do not change the limit in sample applications.

2020-07-08samples: bpf: Refactor BPF map in map test with libbpfDaniel T. Lee1-5/+48
From commit 646f02ffdd49 ("libbpf: Add BTF-defined map-in-map support"), a way to define internal map in BTF-defined map has been added. Instead of using previous 'inner_map_idx' definition, the structure to be used for the inner map can be directly defined using array directive. __array(values, struct inner_map) This commit refactors map in map test program with libbpf by explicitly defining inner map with BTF-defined format.

2018-05-15samples: bpf: include bpf/bpf.h instead of local libbpf.hJakub Kicinski1-1/+1
There are two files in the tree called libbpf.h which is becoming problematic. Most samples don't actually need the local libbpf.h they simply include it to get to bpf/bpf.h. Include bpf/bpf.h directly instead.
