bpf, selftests: Add three new sockmap tests for verdict only programs
Here we add three new tests for sockmap to test having a verdict program without setting the parser program. The first test covers the most simply case, sender proxy_recv proxy_send recv | | | | verdict -----+ | | | | | +----------------+ +------------+ We load the verdict program on the proxy_recv socket without a parser program. It then does a redirect into the send path of the proxy_send socket using sendpage_locked(). Next we test the drop case to ensure if we kfree_skb as a result of the verdict program everything behaves as expected. Next we test the same configuration above, but with ktls and a redirect into socket ingress queue. Shown here tls tls sender proxy_recv proxy_send recv | | | | verdict ------------------+ | | redirect_ingress +----------------+ Also to set up ping/pong test Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/160239302638.8495.17125996694402793471.stgit@john-Precision-5820-Tower
