selftests: drv-net: rss_ctx: don't fail reconfigure test if queue offset not supported

2025-02-04T02:39:23+00:00

Vast majority of drivers does not support queue offset.
Simply return if the rss context + queue ntuple fails.

net: netdevsim: try to close UDP port harness races

2025-01-27T22:24:34+00:00

syzbot discovered that we remove the debugfs files after we free
the netdev. Try to clean up the relevant dir while the device
is still around.

selftests: drv-net-hw: inject pp_alloc_fail errors in the right place

2025-01-17T01:18:53+00:00

The tool pp_alloc_fail.py tested error recovery by injecting errors
into the function page_pool_alloc_pages(). The page pool allocation
function page_pool_dev_alloc() does not end up calling
page_pool_alloc_pages(). page_pool_alloc_netmems() seems to be the
function that is called by all of the page pool alloc functions in
the API, so move error injection to that function instead.

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

2025-01-15T22:42:12+00:00

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.

selftests/net/forwarding: teamd command not found

2025-01-15T22:14:40+00:00

Running "make kselftest TARGETS=net/forwarding" results in
multiple ccurrences of the same error:
- ./lib.sh: line 787: teamd: command not found

This patch adds the variable $REQUIRE_TEAMD in every test that uses the
command teamd and checks the $REQUIRE_TEAMD variable in the file "lib.sh"
to skip the test if the command is not installed.

selftests: net: Adapt ethtool mq tests to fix in qdisc graft

2025-01-15T09:28:51+00:00

Because of patch[1] the graft behaviour changed

So the command:

tcq replace parent 100:1 handle 204:

Is no longer valid and will not delete 100:4 added by command:

tcq replace parent 100:4 handle 204: pfifo_fast

So to maintain the original behaviour, this patch manually deletes 100:4
and grafts 100:1

Note: This change will also work fine without [1]

netconsole: selftest: verify userdata entry limit

2025-01-10T02:06:36+00:00

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.
