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
