selftests: drv-net: Test queue xsk attribute

2025-02-18T00:46:03Z

Test that queues which are used for AF_XDP have the xsk nest attribute. The attribute is currently empty, but its existence means the AF_XDP is being used for the queue. Enable CONFIG_XDP_SOCKETS for selftests/drivers/net tests, as well.

netconsole: selftest: test for sysdata CPU

2025-02-10T15:04:18Z

Add a new selftest to verify that the netconsole module correctly handles CPU runtime data in sysdata. The test validates three scenarios: 1. Basic CPU sysdata functionality - verifies that cpu=X is appended to messages 2. CPU sysdata with userdata - ensures CPU data works alongside userdata 3. Disabled CPU sysdata - confirms no CPU data is included when disabled The test uses taskset to control which CPU sends messages and verifies the reported CPU matches the one used. This helps ensure that netconsole accurately tracks and reports the originating CPU of messages. Signed-off-by: Breno Leitao Reviewed-by: Simon Horman Signed-off-by: David S. Miller

netconsole: selftest: Add test for fragmented messages

2025-02-05T02:09:21Z

Add a new selftest to verify netconsole's handling of messages that exceed the packet size limit and require fragmentation. The test sends messages with varying sizes and userdata, validating that: 1. Large messages are correctly fragmented and reassembled 2. Userdata fields are properly preserved across fragments 3. Messages work correctly with and without kernel release version appending The test creates a networking environment using netdevsim, sends messages through /dev/kmsg, and verifies the received fragments maintain message integrity.

selftest: net-drv: hds: add test for HDS feature

2025-01-15T22:42:12Z

HDS/HDS-thresh features were updated/implemented. so add some tests for these features. HDS tests are the same with `ethtool -G eth0 tcp-data-split ` but `auto` depends on driver specification. So, it doesn't include `auto` case. HDS-thresh tests are same with `ethtool -G eth0 hds-thresh <0 - MAX>` It includes both 0 and MAX cases. It also includes exceed case, MAX + 1.

netconsole: selftest: verify userdata entry limit

2025-01-10T02:06:36Z

Add a new selftest for netconsole that tests the userdata entry limit functionality. The test performs two key verifications: 1. Create MAX_USERDATA_ITEMS (16) userdata entries successfully 2. Confirm that attempting to create an additional userdata entry fails The selftest script uses the netcons library and checks the behavior by attempting to create entries beyond the maximum allowed limit.

netconsole: selftest: Split the helpers from the selftest

2025-01-10T02:06:36Z

Split helper functions from the netconsole basic test into a separate library file to enable reuse across different netconsole tests. This change only moves the existing helper functions to lib/sh/lib_netcons.sh while preserving the same test functionality. The helpers provide common functions for: - Setting up network namespaces and interfaces - Managing netconsole dynamic targets - Setting user data - Handling test dependencies - Cleanup operations Do not make any change in the code, other than the mechanical separation.

net: netconsole: selftests: Create a new netconsole selftest

2024-08-26T16:27:15Z

Adds a selftest that creates two virtual interfaces, assigns one to a new namespace, and assigns IP addresses to both. It listens on the destination interface using socat and configures a dynamic target on netconsole, pointing to the destination IP address. The test then checks if the message was received properly on the destination interface.

net: selftest: add test for netdev netlink queue-get API

2024-05-09T01:59:47Z

Add a selftest for netdev generic netlink. For now there is only a single test that exercises the `queue-get` API. The test works with netdevsim by default or with a real device by setting NETIF. Add a timeout param to cmd() since ethtool -L can take a long time on real devices.
