selftests: bonding: add delay before each xvlan_over_bond connectivity check

2025-12-18T13:00:03+00:00

[ Upstream commit 2c28ee720ad14f58eb88a97ec3efe7c5c315ea5d ]

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.

selftests: netdevsim: Fix ethtool-coalesce.sh fail by installing ethtool-common.sh

2025-11-13T20:37:42+00:00

[ Upstream commit d01f8136d46b925798abcf86b35a4021e4cfb8bb ]

The script "ethtool-common.sh" is not installed in INSTALL_PATH, and
triggers some errors when I try to run the test
'drivers/net/netdevsim/ethtool-coalesce.sh':

  TAP version 13
  1..1

  # selftests: drivers/net/netdevsim: ethtool-coalesce.sh

  # FAILED /0 checks
  not ok 1 selftests: drivers/net/netdevsim: ethtool-coalesce.sh # exit=1

Install this file to avoid this error. After this patch:

  # PASSED all 22 checks

selftests: ncdevmem: don't retry EFAULT

2025-11-13T20:37:15+00:00

[ Upstream commit 8c0b9ed2401b9b3f164c8c94221899a1ace6e9ab ]

devmem test fails on NIPA. Most likely we get skb(s) with readable
frags (why?) but the failure manifests as an OOM. The OOM happens
because ncdevmem spams the following message:

  recvmsg ret=-1
  recvmsg: Bad address

As of today, ncdevmem can't deal with various reasons of EFAULT:
- falling back to regular recvmsg for non-devmem skbs
- increasing ctrl_data size (can't happen with ncdevmem's large buffer)

Exit (cleanly) with error when recvmsg returns EFAULT. This should at
least cause the test to cleanup its state.

selftests: drv-net: rss_ctx: make the test pass with few queues

2025-11-13T20:37:12+00:00

[ Upstream commit e2cf2d5baa09248d3d50b73522594b778388e3bc ]

rss_ctx.test_rss_key_indir implicitly expects at least 5 queues,
as it checks that the traffic on first 2 queues is lower than
the remaining queues when we use all queues. Special case fewer
queues.

selftests: drv-net: rss_ctx: fix the queue count check

2025-11-13T20:37:08+00:00

[ Upstream commit c158b5a570a188b990ef10ded172b8b93e737826 ]

Commit 0d6ccfe6b319 ("selftests: drv-net: rss_ctx: check for all-zero keys")
added a skip exception if NIC has fewer than 3 queues enabled,
but it's just constructing the object, it's not actually rising
this exception.

Before:

selftests: drv-net: hds: restore hds settings

[ Upstream commit ee3ae27721fb994ac0b4705b5806ce68a5a74c73 ]

The test currently modifies the HDS settings and doesn't restore them.
This may cause subsequent tests to fail (or pass when they should not).
Add defer()ed reset handling.

selftests: drv-net: wait for carrier

2025-11-13T20:37:01+00:00

[ Upstream commit f09fc24dd9a5ec989dfdde7090624924ede6ddc7 ]

On fast machines the tests run in quick succession so even
when tests clean up after themselves the carrier may need
some time to come back.

Specifically in NIPA when ping.py runs right after netpoll_basic.py
the first ping command fails.

Since the context manager callbacks are now common NetDrvEpEnv
gets an ip link up call as well.

selftests: drv-net: devmem: flip the direction of Tx tests

2025-11-13T20:36:59+00:00

[ Upstream commit c378c497f3fe8dc8f08b487fce49c3d96e4cada8 ]

The Device Under Test should always be the local system.
While the Rx test gets this right the Tx test is sending
from remote to local. So Tx of DMABUF memory happens on remote.

These tests never run in NIPA since we don't have a compatible
device so we haven't caught this.
