From a24fb420a5775581050026eba2264c87927debf7 Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Sat, 10 Oct 2020 22:10:26 -0700 Subject: [PATCH] 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 Signed-off-by: Alexei Starovoitov Link: https://lore.kernel.org/bpf/160239302638.8495.17125996694402793471.stgit@john-Precision-5820-Tower --- tools/testing/selftests/bpf/test_sockmap.c | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/bpf/test_sockmap.c b/tools/testing/selftests/bpf/test_sockmap.c index 419c0b0..0fa1e42 100644 --- a/tools/testing/selftests/bpf/test_sockmap.c +++ b/tools/testing/selftests/bpf/test_sockmap.c @@ -1472,12 +1472,29 @@ static void test_txmsg_skb(int cgrp, struct sockmap_options *opt) txmsg_ktls_skb_drop = 0; txmsg_ktls_skb_redir = 1; test_exec(cgrp, opt); + txmsg_ktls_skb_redir = 0; + + /* Tests that omit skb_parser */ + txmsg_omit_skb_parser = 1; + ktls = 0; + txmsg_ktls_skb = 0; + test_exec(cgrp, opt); + + txmsg_ktls_skb_drop = 1; + test_exec(cgrp, opt); + txmsg_ktls_skb_drop = 0; + + txmsg_ktls_skb_redir = 1; + test_exec(cgrp, opt); + + ktls = 1; + test_exec(cgrp, opt); + txmsg_omit_skb_parser = 0; opt->data_test = data; ktls = k; } - /* Test cork with hung data.
