Xu Kuohai 90f0074cd9 selftests/bpf: fix a CI failure caused by vsock sockmap test ... BPF CI has reported the following failure: Error: #200/79 sockmap_listen/sockmap VSOCK test_vsock_redir Error: #200/79 sockmap_listen/sockmap VSOCK test_vsock_redir ./test_progs:vsock_unix_redir_connectible:1506: egress: write: Transport endpoint is not connected vsock_unix_redir_connectible:FAIL:1506 ./test_progs:vsock_unix_redir_connectible:1506: ingress: write: Transport endpoint is not connected vsock_unix_redir_connectible:FAIL:1506 ./test_progs:vsock_unix_redir_connectible:1506: egress: write: Transport endpoint is not connected vsock_unix_redir_connectible:FAIL:1506 ./test_progs:vsock_unix_redir_connectible:1514: ingress: recv() err, errno=11 vsock_unix_redir_connectible:FAIL:1514 ./test_progs:vsock_unix_redir_connectible:1518: ingress: vsock socket map failed, a != b vsock_unix_redir_connectible:FAIL:1518 ./test_progs:vsock_unix_redir_connectible:1525: ingress: want pass count 1, have 0 It’s because the recv(... MSG_DONTWAIT) syscall in the test case is called before the queued work sk_psock_backlog() in the kernel finishes executing. So the data to be read is still queued in psock->ingress_skb and cannot be read by the user program. Therefore, the non-blocking recv() reads nothing and reports an EAGAIN error. So replace recv(... MSG_DONTWAIT) with xrecv_nonblock(), which calls select() to wait for data to be readable or timeout before calls recv().
