selftests: netconsole: Increase port listening timeout

2026-02-26T22:59:38+00:00

[ Upstream commit a68a9bd086c2822d0c629443bd16ad1317afe501 ] wait_for_port() can wait up to 2 seconds with the sleep and the polling in wait_local_port_listen() combined. So, in netcons_basic.sh, the socat process could die before the test writes to the netconsole. Increase the timeout to 3 seconds to make netcons_basic.sh pass consistently.

selftests: netconsole: remove log noise due to socat exit

2026-02-26T22:59:37+00:00

[ Upstream commit e3b8cbf40c6e60a7a935bd8980884d5741a7a77b ] This removes some noise that can be distracting while looking at selftests by redirecting socat stderr to /dev/null. Before this commit, netcons_basic would output: Running with target mode: basic (ipv6) 2025/11/29 12:08:03 socat[259] W exiting on signal 15 2025/11/29 12:08:03 socat[271] W exiting on signal 15 basic : ipv6 : Test passed Running with target mode: basic (ipv4) 2025/11/29 12:08:05 socat[329] W exiting on signal 15 2025/11/29 12:08:05 socat[322] W exiting on signal 15 basic : ipv4 : Test passed Running with target mode: extended (ipv6) 2025/11/29 12:08:08 socat[386] W exiting on signal 15 2025/11/29 12:08:08 socat[386] W exiting on signal 15 2025/11/29 12:08:08 socat[380] W exiting on signal 15 extended : ipv6 : Test passed Running with target mode: extended (ipv4) 2025/11/29 12:08:10 socat[440] W exiting on signal 15 2025/11/29 12:08:10 socat[435] W exiting on signal 15 2025/11/29 12:08:10 socat[435] W exiting on signal 15 extended : ipv4 : Test passed After these changes, output looks like: Running with target mode: basic (ipv6) basic : ipv6 : Test passed Running with target mode: basic (ipv4) basic : ipv4 : Test passed Running with target mode: extended (ipv6) extended : ipv6 : Test passed Running with target mode: extended (ipv4) extended : ipv4 : Test passed Signed-off-by: Andre Carvalho Reviewed-by: Simon Horman Link: https://patch.msgid.link/20251129-netcons-socat-noise-v1-1-605a0cea8fca@gmail.com Signed-off-by: Jakub Kicinski Stable-dep-of: a68a9bd086c2 ("selftests: netconsole: Increase port listening timeout") Signed-off-by: Sasha Levin

selftest: netcons: add test for netconsole over bonded interfaces

2025-11-11T02:34:44+00:00

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.

selftest: netcons: refactor target creation

2025-11-11T02:34:44+00:00

Extract the netconsole target creation from create_dynamic_target(), by moving it from create_dynamic_target() into a new helper function. This enables other tests to use the creation of netconsole targets with arbitrary parameters and no sleep. The new helper will be utilized by forthcoming torture-type selftests that require dynamic target management.

selftests: drv-net: make linters happy with our imports

2025-10-07T10:12:44+00:00

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.

selftests: drv-net: wait for carrier

2025-08-15T00:44:46+00:00

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.
