00f3b32518 selftests: netconsole: ensure required log level is set on netcons_basic
This commit ensures that the required log level is set at the start of
the test iteration.

Part of the cleanup performed at the end of each test iteration resets
the log level (do_cleanup in lib_netcons.sh) to the values defined at the
time test script started. This may cause further test iterations to fail
if the default values are not sufficient.

5aadc15584 selftests: hw-net: toeplitz: give the test up to 4 seconds
Increase the receiver timeout. When running between machines
in different geographic regions the test needs more than
a second to SSH across and send the frames.

The bkg() command that runs the receiver defaults to 5 sec timeout,
so using 4 sec sounds like a reasonable value for the receiver itself.

f81171fecd selftests: hw-net: auto-disable building the iouring C code
Looks like the liburing is not updated by distros very aggressively.
Presumably because a lot of packages depend on it. I just updated
to Fedora 43 and it's still on liburing 2.9. The test is 9mo old,
at this stage I think this warrants handling the build failure
more gracefully.

Detect if iouring is recent enough and if not print a warning
and exclude the C prog from build. The Python test will just
fail since the binary won't exist. But it removes the major
annoyance of having to update liburing from sources when
developing other tests.

8be656cfb9 selftest: netdevsim: test devlink default params
Test querying default values and resetting to default values for
netdevsim devlink params.

This should cover the basic paths of interest: driverinit and
non-driverinit cmodes, as well as bool and non-bool value
type. Default param values of type bool are encoded with u8 netlink
type as opposed to flag type, so that userspace can distinguish
"not-present" from false.

5ad9945341 netconsole: Increase MAX_USERDATA_ITEMS
Increase MAX_USERDATA_ITEMS from 16 to 256 entries now that the userdata
buffer is allocated dynamically.

The previous limit of 16 was necessary because the buffer was statically
allocated for all targets. With dynamic allocation, we can support more
entries without wasting memory on targets that don't use userdata.

This allows users to attach more metadata to their netconsole messages,
which is useful for complex debugging and logging scenarios.

Also update the testcase accordingly.

The GRO test can run on a real device or a veth.
The Toeplitz hash test can only run on a real device.
Move them from net/ to drivers/net/ and drivers/net/hw/ respectively.

There are two scripts which set up the environment for these tests
setup_loopback.sh and setup_veth.sh. Move those scripts to net/lib.
The paths to the setup files are a little ugly but they will be
deleted shortly.

toeplitz_client.sh is not a test in itself, but rather a helper
to send traffic, so add it to TEST_FILES rather than TEST_PROGS.

6ae67f1159 selftests: net: py: add test variants
There's a lot of cases where we try to re-run the same code with
different parameters. We currently need to either use a generator
method or create a "main" case implementation which then gets called
by trivial case functions:

  def _test(x, y, z):
     ...

  def case_int():
     _test(1, 2, 3)

  def case_str():
     _test('a', 'b', 'c')

Add support for variants, similar to kselftests_harness.h and
a lot of other frameworks. Variants can be added as decorator
to test functions:

  @ksft_variants([(1, 2, 3), ('a', 'b', 'c')])
  def case(x, y, z):
     ...

ksft_run() will auto-generate case names:
  case.1_2_3
  case.a_b_c

Because the names may not always be pretty (and to avoid forcing
classes to implement case-friendly __str__()) add a wrapper class
KsftNamedVariant which lets the user specify the name for the variant.

Note that ksft_run's args are still supported. ksft_run splices args
and variant params together.

eca8b8fc74 selftests: drv-net: xdp: make the XDP qstats tests less flaky
The XDP qstats tests send 2k packets over a single socket.
Looks like when netdev CI is busy running those tests in QEMU
occasionally flakes. The target doesn't get to run at all
before all 2000 packets are sent.

Lower the number of packets to 1000 and reopen the socket
every 50 packets, to give RSS a chance to spread the packets
to multiple queues.

For the netdev CI testing either lowering the count or using
multiple sockets is enough, but let's do both for extra resiliency.

236682db3b selftest: netcons: add test for netconsole over bonded interfaces
This patch adds a selftest that verifies netconsole functionality
over bonded network interfaces using netdevsim. It sets up two bonded
interfaces acting as transmit (TX) and receive (RX) ends, placed in
separate network namespaces. The test sends kernel log messages and
verifies that they are properly received on the bonded RX interfaces
with both IPv4 and IPv6, and using basic and extended netconsole
formats.

This patchset aims to test a long-standing netpoll subsystem where
netpoll has multiple users. (in this case netconsole and bonding). A
similar selftest has been discussed in [1] and [2].

This test also tries to enable bonding and netpoll in different order,
just to guarantee that all the possibilities are exercised.

6701896eb9 selftest: netcons: create a torture test
Create a netconsole test that puts a lot of pressure on the netconsole
list manipulation. Do it by creating dynamic targets and deleting
targets while messages are being sent. Also put interface down while the
messages are being sent, as creating parallel targets.

The code launches three background jobs on distinct schedules:

 * Toggle netcons target every 30 iterations
 * create and delete random_target every 50 iterations
 * toggle iface every 70 iterations

This creates multiple concurrency sources that interact with netconsole
states. This is good practice to simulate stress, and exercise netpoll
and netconsole locks.

This test already found an issue as reported in [1]

b615879dbf selftests: drv-net: make linters happy with our imports
Linters are still not very happy with our __init__ files,
which was pointed out in recent review (see Link).

We have previously started importing things one by one to
make linters happy with the test files (which import from __init__).
But __init__ file itself still makes linters unhappy.

To clean it up I believe we must completely remove the wildcard
imports, and assign the imported modules to __all__.

hds.py needs to be fixed because it seems to be importing
the Python standard random from lib.net.

We can't use ksft_pr() / ktap_result() in case importing
from net.lib fails. Linters complain that those helpers
themselves may not have been imported.

f07f91a360 selftests: net: unify the Makefile formats
We get a significant number of conflicts between net and net-next
because of selftests Makefile changes. People tend to append new
test cases at the end of the Makefile when there's no clear sort
order. Sort all networking selftests Makefiles, use the following
format:

 VAR_NAME := \
	 entry1 \
	 entry2 \
	 entry3 \
 # end of VAR_NAME

Some Makefiles are already pretty close to this.

This introduces a test for IPSec offload over bonding, utilizing netdevsim
for the testing process, as veth interfaces do not support IPSec offload.
The test will ensure that the IPSec offload functionality remains operational
even after a failover event occurs in the bonding configuration.

Here is the test result:

TEST: bond_ipsec_offload (active_slave eth0)                        [ OK ]
TEST: bond_ipsec_offload (active_slave eth1)                        [ OK ]

b9c8a2c567 selftests: drv-net: add HW timestamping tests
Add simple tests to validate that the driver sets up timestamping
configuration according to what is reported in capabilities.

For RX timestamping we allow driver to fallback to wider scope for
timestamping if filter is applied. That actually means that driver
can enable ptpv2-event when it reports ptpv2-l4-event is supported,
but not vice versa.

RX devmem sometimes fails on NIPA:

Both RSS and flow steering are properly installed, but the wait_port_listen
fails. Try to remove sleep(1) to see if the cause of the failure is
spending too much time during RX setup. I don't see a good reason to
have sleep in the first place. If there needs to be a delay between
installing the rules and receiving the traffic, let's add it to the
callers (devmem.py) instead.
