From 3886ea9b87c416c080078603fedea95bcc144442 Mon Sep 17 00:00:00 2001 From: Tony Ambardar Date: Mon, 17 May 2021 11:57:40 -0700 Subject: [PATCH] kselftests-bpf: add kernel BPF tests Build and package kernel self-tests used for BPF testing, program and JIT development. This package, together with the existing 'kmod-bpf-test', was extensively used for past upstream Linux JIT submissions [1]. Currently this includes only 'test_verifier'; building 'test_progs' will fail due to known endian limitations with bpftool skeletons.
