From ba72a7b4badbf4dd3c49c585c3c662bacc54f46e Mon Sep 17 00:00:00 2001 From: Alexei Starovoitov Date: Thu, 31 Jan 2019 15:40:12 -0800 Subject: selftests/bpf: test for BPF_F_LOCK Add C based test that runs 4 bpf programs in parallel that update the same hash and array maps. And another 2 threads that read from these two maps via lookup(key, value, BPF_F_LOCK) api to make sure the user space sees consistent value in both hash and array elements while user space races with kernel bpf progs.
