vsock/test: verify socket options after setting them

2026-02-16T09:17:49+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.)

Several tests are missing here compared to upstream, so this version has been adapted by removing some hunks.] Signed-off-by: Stefano Garzarella Signed-off-by: Greg Kroah-Hartman

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

2026-01-30T09:27:24+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: rework message bounds test

2023-01-12T11:53:54+00:00

This updates message bound test making it more complex. Instead of sending 1 bytes messages with one MSG_EOR bit, it sends messages of random length(one half of messages are smaller than page size, second half are bigger) with random number of MSG_EOR bits set. Receiver also don't know total number of messages. Signed-off-by: Arseniy Krasnov Reviewed-by: Stefano Garzarella Signed-off-by: Paolo Abeni

vsock_test: add SOCK_SEQPACKET tests

2021-06-11T20:32:47+00:00

Implement two tests of SOCK_SEQPACKET socket: first sends data by several 'write()'s and checks that number of 'read()' were same. Second test checks MSG_TRUNC flag. Cases for connect(), bind(), etc. are not tested, because it is same as for stream socket. Signed-off-by: Arseny Krasnov Signed-off-by: David S. Miller

testing/vsock: add parameters to list and skip tests

2019-12-21T05:09:21+00:00

Some tests can fail with transports that have a slightly different behavior, so let's add the possibility to specify which tests to skip. Signed-off-by: Stefano Garzarella Signed-off-by: David S. Miller

vsock_test: wait for the remote to close the connection

2019-12-21T05:09:21+00:00

Before check if a send returns -EPIPE, we need to make sure the connection is closed. To do that, we use epoll API to wait EPOLLRDHUP or EPOLLHUP events on the socket. Reported-by: Jorgen Hansen Signed-off-by: Stefano Garzarella Signed-off-by: David S. Miller

VSOCK: add send_byte()/recv_byte() test utilities

VSOCK: extract connect/accept functions from vsock_diag_test.c

2019-12-21T05:09:21+00:00

Many test cases will need to connect to the server or accept incoming connections. This patch extracts these operations into utility functions that can be reused. Signed-off-by: Stefan Hajnoczi Signed-off-by: Stefano Garzarella Signed-off-by: David S. Miller
