increases the flexibility of KEXEC Handover. Also preparation for LUO
- "Live Update Orchestrator" (Pasha Tatashin)
is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.

Currently, tolerance is computed against the TC’s expected percentage,

Commit 7c32f7a2d3db ("selftests: net: py: don't default to shell=True")
changed the cmd() helper to avoid spawning a shell unless explicitly
requested.
The devlink_rate_tc_bw test enables SR-IOV by writing to the
sriov_numvfs sysfs attribute using redirection. Without shell=True the
redirection is not interpreted and the VF device never appears,
causing the test to fail.
Fix by explicitly passing shell=True in the two places that update
sriov_numvfs.

GenerateTraffic was added to spin up long-running iperf3 load, mainly
to drive high PPS background traffic. It was never meant to provide
stable throughput numbers, and trying to repurpose it for measurement
does not make sense.
Introduce Iperf3Runner to allow tests to split out server/client
configuration, control start/stop, and collect JSON output for
analysis. This makes it possible to measure bandwidth directly when
validating egress shaping.
GenerateTraffic stays as the background load generator, reusing the
common iperf3 helpers under the hood.

Jakub reported increased flakiness in bond_macvlan_ipvlan.sh on regular
kernel, while the tests consistently pass on a debug kernel. This suggests
a timing-sensitive issue.
To mitigate this, introduce a short sleep before each xvlan_over_bond
connectivity check. The delay helps ensure neighbor and route cache
have fully converged before verifying connectivity.
The sleep interval is kept minimal since check_connection() is invoked
nearly 100 times during the test.

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.

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.

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.

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 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

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.

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.

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.

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.

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]

We are trying to move away from netdevsim-only tests and towards
tests which can be run both against netdevsim and real drivers.
Replace the simple bash script we have for checking ethtool -g/-G
on netdevsim with a Python test tweaking those params as well
as channel count.
The new test is not exactly equivalent to the netdevsim one,
but real drivers don't often support random ring sizes,
let alone modifying max values via debugfs.

Lower the expected level of traffic in the pp_alloc_fail test
and calculate failure counter thresholds based on the traffic
rather than using a fixed constant.
We only have "QEMU HW" in NIPA right now, and the test (due to
debug dependencies) only works on debug kernels in the first place.
We need some place for it to pass otherwise it seems to be bit
rotting. So lower the traffic threshold so that it passes on QEMU
and with a debug kernel...

XDP is the first layer of the stack so we should see Rx and Tx

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.

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.
