2025-05-27vsock/test: Add test for an unexpectedly lingering close()Michal Luczaj
There was an issue with SO_LINGER: instead of blocking until all queued messages for the socket have been successfully sent (or the linger timeout has been reached), close() would block until packets were handled by the peer. Add a test to alert on close() lingering when it should not.

2025-05-16vsock/test: check also expected errno on sigpipe testStefano Garzarella

2025-05-16vsock/test: retry send() to avoid occasional failure in sigpipe testStefano Garzarella
When the other peer calls shutdown(SHUT_RD), there is a chance that the send() call could occur before the message carrying the close information arrives over the transport. In such cases, the send() might still succeed. To avoid this race, let's retry the send() call a few times, ensuring the test is more reliable. Sleep a little before trying again to avoid flooding the other peer and filling its receive buffer, causing false-negative.

2025-05-13vsock/test: Fix occasional failure in SIOCOUTQ testsKonstantin Shkolnyy
These tests: "SOCK_STREAM ioctl(SIOCOUTQ) 0 unsent bytes" "SOCK_SEQPACKET ioctl(SIOCOUTQ) 0 unsent bytes" output: "Unexpected 'SIOCOUTQ' value, expected 0, got 64 (CLIENT)". They test that the SIOCOUTQ ioctl reports 0 unsent bytes after the data have been received by the other side. However, sometimes there is a delay in updating this "unsent bytes" counter, and the test fails even though the counter properly goes to 0 several milliseconds later. The delay occurs in the kernel because the used buffer notification callback virtio_vsock_tx_done(), called upon receipt of the data by the other side, doesn't update the counter itself. It delegates that to a kernel thread (via vsock->tx_work). Sometimes that thread is delayed more than the test expects. Change the test to poll SIOCOUTQ until it returns 0 or a timeout occurs.

2024-12-05vsock/test: fix failures due to wrong SO_RCVLOWAT parameterKonstantin Shkolnyy
This happens on 64-bit big-endian machines. SO_RCVLOWAT requires an int parameter. However, instead of int, the test uses unsigned long in one place and size_t in another. Both are 8 bytes long on 64-bit machines. The kernel, having received the 8 bytes, doesn't test for the exact size of the parameter, it only cares that it's >= sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT returns with success and the socket stays with the default SO_RCVLOWAT = 1, which results in vsock_test failures, while vsock_perf doesn't even notice that it's failed to change it.

This new test runs the server side so that it binds to the socket without ever listening to it. The client side will try to connect and should receive an ECONNRESET error.
