2024-01-11qtest: ensure netdev-socket tests have non-overlapping namesDaniel P. Berrangé
When naming glib tests if the name of one test is a substring of the name of another test, it is not possible to use the '-p /the/name' option to run a single test. Signed-off-by: "Daniel P. Berrangé" <berrange@redhat.com> Message-ID: <20240104162942.211458-7-berrange@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
2024-01-11net: add explicit info about connecting/listening stateDaniel P. Berrangé
When running 'info network', if the stream backend is still in the process of connecting, or waiting for an incoming connection, no information is displayed. There is also no way to distinguish whether the server is still in the process of setting up the listener socket, or whether it is ready to accept incoming client connections. This leads to a race condition in the netdev-socket qtest which launches a server process followed by a client process. Under high load conditions it is possible for the client to attempt to connect before the server is accepting clients. For the scenarios which do not set the 'reconnect' option, this opens up a race which can lead to the test scenario failing to reach the expected state. Now that 'info network' can distinguish between initialization phase and the listening phase, the netdev-socket qtest will correctly synchronize, such that the client QEMU is not spawned until the server is ready. This should solve the non-deterministic failures seen with the netdev-socket qtest. Signed-off-by: "Daniel P.

2024-01-11Revert "tests/qtest/netdev-socket: Raise connection timeout to 120 seconds"Daniel P. Berrangé
This reverts commit 0daaf2761f6d268ffaa2d01d450e202e127452b1. The test was not timing out because of slow execution. It was timing out due to a race condition leading to the client QEMU attempting (and fatally failing) to connect before the server QEMU was listening. Signed-off-by: "Daniel P.

2023-12-01netdev: set timeout depending on loadavgMichael S. Tsirkin
netdev test keeps failing sometimes. I don't think we should increase the timeout some more: let's try something else instead, testing how busy the system is. Seems to work for me. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2023-08-31tests/qtest/netdev-socket: Avoid variable-length array in ↵Peter Maydell
inet_get_free_port_multiple() We use a variable-length array in inet_get_free_port_multiple(). This is only test code called at the start of a test, so switch to a heap allocation instead. The codebase has very few VLAs, and if we can get rid of them all we can make the compiler error on new additions. This is a defensive measure against security bugs where an on-stack dynamic allocation isn't correctly size-checked (e.g. CVE-2021-3527).

2023-02-17net: stream: add a new option to automatically reconnectLaurent Vivier
In stream mode, if the server shuts down there is currently no way to reconnect the client to a new server without removing the NIC device and the netdev backend (or to reboot). This patch introduces a reconnect option that specifies a delay to try to reconnect with the same parameters. Add a new test in qtest to test the reconnect option and the connect/disconnect events.
