Miller" , Jakub Kicinski , Paolo Abeni , Andrew Lunn , Shuah Khan Cc: Simon Horman , Jakub Sitnicki , Daniel Zahka , Willem de Bruijn , netdev@vger.kernel.org, linux-kselftest@vger.kernel.org, linux-kernel@vger.kernel.org, bpf@vger.kernel.org, Wei Wang Content-Type: text/plain; charset="UTF-8" _data_basic_send() and _data_basic_send_netkit_psp_assoc() currently only verify unidirectional data transmission from the test socket to psp_responder. As a result, they do not exercise the receive path for PSP-encrypted TCP data segments arriving at the test socket (such as packets redirected across a netkit interface associated via dev-assoc, which relies on SKB_EXT_PSP surviving packet scrubbing). Use the existing "data echo" command in psp_responder to verify that the test socket can also receive PSP-encrypted data from the peer in both _data_basic_send() and _data_basic_send_netkit_psp_assoc().
