selftests: drv-net: so_txtime: relax variance bounds

2026-08-03T09:26:04+00:00

commit e38fec239d923de5bfb65f7fce15ca52c5a3aa7f upstream.

The net-next-hw spinners on netdev.bots.linux.dev observe failing
so-txtime-py tests. A review of stdout shows most failures to be
due to exceeding the 4ms grace period. All I saw were within 8ms.
So increase to that.

Double the bounds from 4 to 8ms. This is still is small enough to
differentiate the delays programmed by the test, 10 and 20ms.

selftests: drv-net: cope with slow env in so_txtime.py test

2026-08-03T09:26:04+00:00

commit 543bdc1578cd380631558a884318551a0e9fdab2 upstream.

This test was converted from shell script to drv-net test.

The new version is flaky in dbg builds on the netdev.bots dashboard.
The previous shell script had more protections to avoid these. Added
in commit a7ee79b9c455 ("selftests: net: cope with slow env in
so_txtime.sh test").

Add the same overall protection:

- Suppress so_txtime process failure if KSFT_MACHINE_SLOW

Also relax two timeouts to reduce the number of process failures
themselves

- Increase SO_RCVTIMEO to 2 seconds
- Increase process start-up stabilization to 2 seconds

Delays were experimentally arrived at while running with vng
built with kernel/configs/debug.config

selftests: drv-net: add missing kconfig for psp.py

2026-08-03T09:26:02+00:00

[ Upstream commit c25dd7439f84cf607e13d6de8cc1c79cd51f56ff ]

This psp.py selftest was failing on my side when only using the
drivers/net config file on top of the default one -- the recommended way
to execute selftest targets.

It looks like some kernel config are needed to execute the new tc
commands.

Note that this was not visible on NIPA, because these tests are executed
with the drivers/net/hw ones, combining the two config files, and the hw
one contains the missing ones.

selftests: mptcp: userspace_pm: fix undefined variable port

2026-08-03T09:25:54+00:00

commit e3213292c4fd69ba442c6ed4693f91a92b753140 upstream.

In make_connection(), the variable "port" is used but never defined.
This leads to an empty argument being passed to wait_local_port_listen(),
causing "printf: : invalid number" errors:

 # INFO: Init
 # 01 Created network namespaces ns1, ns2                          [ OK ]
 # INFO: Make connections
 # ./../lib.sh: line 651: printf: : invalid number
 # 02 Established IPv4 MPTCP Connection ns2 => ns1                 [ OK ]
 # INFO: Connection info: 10.0.1.2:59516 -> 10.0.1.1:50002
 # ./../lib.sh: line 651: printf: : invalid number
 # 03 Established IPv6 MPTCP Connection ns2 => ns1                 [ OK ]

Fix it by using the correctly defined variable "app_port", which holds the
appropriate port number for the connection.

selftests: ntsync: correct CONFIG_NTSYNC name

2026-08-03T09:25:53+00:00

commit f97752cfe511c1ed9933057455c73aaac07d6517 upstream.

The config fragment for these tests defines CONFIG_WINESYNC, which
refers to an earlier name for the ntsync driver before it was merged
[1]. Correct it to define CONFIG_NTSYNC instead.

selftests: drv-net: convert so_txtime to drv-net

2026-08-03T09:25:33+00:00

[ Upstream commit 5c6baef3885c0e16e63d432fe31aa6f7e98e18dc ]

In preparation for extending to pacing hardware offload, convert the
so_txtime.sh test to a drv-net test that can be run against netdevsim
and real hardware.

Also update so_txtime.c to not exit on first failure, but run to
completion and report exit code there. This helps with debugging
unexpected results, especially when processing multiple packets,
as happens in the "reverse_order" testcase.

----

v6 -> v7

- update test to use new argument expect_fail
- v6 received Reviewed-by, but dropped due to above (minor) change

v5 -> v6

- fix order in tools/testing/selftests/drivers/net/config

v4 -> v5

- move qdisc setup/restore into each test
- add tc to utils.py (separate patch)
- test expected failure (separate patch)
- fix pylint
- convert fail to pass for timing errors if KSFT_MACHINE_SLOW
  (cmd does not special case KSFT_SKIP process returncode yet)

Responses to sashiko review

- The test converts per packet failure to errors, to continue
  testing other packets, but other error() cases are not in scope.
- The test starts sender and receiver at an absolute future time,
  like the original test. This assumes ~msec scale sync'ed clocks.
- The tc qdisc replace command works fine with noqueue. Tested
  manually.

v3 -> v4

- restore original qdisc after test
- drop unnecessary underscore in tap test names

v2 -> v3

- Makefile: so_txtime from YNL_GEN_FILES to TEST_GEN_FILES (Sashiko, NIPA)

v1 -> v2
- move so_txtime.c for net/lib to drivers/net (Jakub)
- fix drivers/net/config order (Jakub)
- detect passing when failure is expected (Jakub, Sashiko)
- pass pylint --disable=R (Jakub)
- only call ksft_run once (Jakub)
- do not sleep if waiting time is negative (Sashiko)
- add \n when converting error() to fprintf() (Sashiko)
- 4 space indentation, instead of 2 space
- increase sync delay from 100 to 200ms, to fix rare vng flakes

selftests: drv-net: increase timeout

2026-08-03T09:25:33+00:00

[ Upstream commit 3529d75d67411497341cd804a045185d6035dff2 ]

The default timeout is 45 seconds, that's too low for the xdp.py test.

Indeed, this test can take up to 3 minutes with some debug kernel config
on NIPA. Set a timeout to 6 minutes, just to be on the safe side.

Note that the Fixes tag here points to the introduction of the xdp.py
test because I don't know when this test started to take more than 45
seconds. That's OK because a timeout of 6 minutes is not exaggerated.

selftests: ovpn: increase timeout

[ Upstream commit 61ac7049aaa86ae044e8a5b94d852218163d5bf8 ]

The default timeout is 45 seconds, that's too low for a few ovpn tests.

Indeed, these tests can take up to 50 seconds with some debug kernel
config on NIPA. Set a timeout to 90 seconds, just to be on the safe
side.

Note that the Fixes tag here points to the introduction of the ovpn
tests because I don't know when they started to take more than 45
seconds. That's OK because a timeout of 1.5 minutes is not exaggerated.

selftests: ovpn: add IPV6 and VETH configs

2026-08-03T09:25:33+00:00

[ Upstream commit 90c792681a3732caaf7bf5bc435877736baf591a ]

They are required to run the selftests:

 - Tests are executed in v4 and v6.

 - Virtual Ethernet are used between the different netns.

This has not been seen on NIPA before, because the 'ovpn' tests are
executed with the 'tcp_ao' ones, merging their config files. These two
kernel config are present in tools/testing/selftests/net/tcp_ao/config.

This issue is visible when only the ovpn config is used on top of the
default one. This is the recommended way to execute selftest targets.

selftests: openvswitch: add config file

2026-08-03T09:25:33+00:00

[ Upstream commit 441a820ccef9af80a9ac5a4c85b9c396e595967c ]

The kselftests doc mentions that a config file should be present "if a
test needs specific kernel config options enabled". This selftest
requires some kernel config, but no config file was provided.

We could say that a sub-target could use the parent's config file, but
the kselftests doc doesn't mention anything about that. Plus the
net/openvswitch target is the only net target without a config file.

Here is a new config file, which is a trimmed version of the net one,
with hopefully the minimal required kconfig on top of 'make defconfig'.

The Fixes tag points to the introduction of the net/openvswitch target,
just to help validating this target on stable kernels.
