vsock/test: verify socket options after setting them

2026-02-12T12:14:57+00:00

commit 86814d8ffd55fd4ad19c512eccd721522a370fb2 upstream. Replace setsockopt() calls with calls to functions that follow setsockopt() with getsockopt() and check that the returned value and its size are the same as have been set. (Except in vsock_perf.)

vsock/test: add a final full barrier after run all tests

2026-01-23T10:18:37+00:00

[ Upstream commit c39a6a277e0e67ffff6a8efcbbf7e7e23ce9e38c ] If the last test fails, the other side still completes correctly, which could lead to false positives. Let's add a final barrier that ensures that the last test has finished correctly on both sides, but also that the two sides agree on the number of tests to be performed.

test/vsock: add ioctl unsent bytes test

2024-08-02T08:20:28+00:00

Introduce two tests, one for SOCK_STREAM and one for SOCK_SEQPACKET, which use SIOCOUTQ ioctl to check that the number of unsent bytes is zero after delivering a packet. vsock_connect and vsock_accept are no longer static: this is to create more generic tests, allowing code to be reused for SEQPACKET and STREAM.

vsock/test: add '--peer-port' input argument

2024-01-25T01:47:35+00:00

Implement port for given CID as input argument instead of using hardcoded value '1234'. This allows to run different test instances on a single CID. Port argument is not required parameter and if it is not set, then default value will be '1234' - thus we preserve previous behaviour.

test/vsock: MSG_ZEROCOPY flag tests

2023-10-15T12:19:42+00:00

This adds three tests for MSG_ZEROCOPY feature: 1) SOCK_STREAM tx with different buffers. 2) SOCK_SEQPACKET tx with different buffers. 3) SOCK_STREAM test to read empty error queue of the socket. Patch also works as preparation for the next patches for tools in this patchset: vsock_perf and vsock_uring_test: 1) Adds several new functions to util.c - they will be also used by vsock_uring_test. 2) Adds two new functions for MSG_ZEROCOPY handling to a new source file - such source will be shared between vsock_test, vsock_perf and vsock_uring_test, thus avoiding code copy-pasting.
