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

2025-11-01T00:41:54+00:00

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 # timeout set to 600 # selftests: drivers/net/netdevsim: ethtool-coalesce.sh # ./ethtool-coalesce.sh: line 4: ethtool-common.sh: No such file or directory # ./ethtool-coalesce.sh: line 25: make_netdev: command not found # ethtool: bad command line argument(s) # ./ethtool-coalesce.sh: line 124: check: command not found # ./ethtool-coalesce.sh: line 126: [: -eq: unary operator expected # FAILED /0 checks not ok 1 selftests: drivers/net/netdevsim: ethtool-coalesce.sh # exit=1 Install this file to avoid this error.

selftests: net: unify the Makefile formats

2025-10-06T20:14:06+00:00

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.

selftests: netdevsim: Xfail nexthop test on slow machines

2025-08-05T23:11:03+00:00

A lot of test cases in the file are related to the idle and unbalanced timers of resilient nexthop groups and these tests are reported to be flaky on slow machines running debug kernels. Rather than marking a lot of individual tests with xfail_on_slow(), simply mark all the tests. Note that the test is stable on non-debug machines and that with debug kernels we are mainly interested in the output of various sanitizers in order to determine pass / fail.

netdevsim: add fw_update_flash_chunk_time_ms debugfs knobs

2025-07-24T00:08:56+00:00

Netdevsim emulates firmware update and it takes 5 seconds to complete. For some use cases, this is too long and unnecessary. Allow user to configure the time by exposing debugfs a knob to set chunk time.

selftests: net: move wait_local_port_listen to lib.sh

2025-05-28T00:31:42+00:00

The function wait_local_port_listen() is the only function defined in net_helper.sh. Since some tests source both lib.sh and net_helper.sh, we can simplify the setup by moving wait_local_port_listen() to lib.sh. With this change, net_helper.sh becomes redundant and can be removed.
