selftests/tc-testing: Enable CONFIG_IP_SET

2025-07-02T00:40:18+00:00

The config snippet specifies CONFIG_NET_EMATCH_IPSET. This option
depends on CONFIG_IP_SET.

Set CONFIG_IP_SET to be enabled at part for tc-testing.

selftests: tc-testing: add missing netfilter config

2024-01-26T00:38:16+00:00

On a default config + tc-testing config build, tdc will miss
all the netfilter related tests because it's missing:

net/sched: Retire ipt action

2024-01-02T12:41:16+00:00

The tc ipt action was intended to run all netfilter/iptables target.
Unfortunately it has not benefitted over the years from proper updates when
netfilter changes, and for that reason it has remained rudimentary.
Pinging a bunch of people that i was aware were using this indicates that
removing it wont affect them.
Retire it to reduce maintenance efforts. Buh-bye.

selftests: tc-testing: add missing Kconfig options to 'config'

2023-10-19T01:07:51+00:00

Make sure CI builds using just tc-testing/config can run all tdc tests.
Some tests were broken because of missing knobs.

selftests: tc: add ConnTrack procfs kconfig

2023-07-18T23:52:12+00:00

When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.

  not ok 373 3992 - Add ct action triggering DNAT tuple conflict
  	Could not match regex pattern. Verify command output:
  cat: /proc/net/nf_conntrack: No such file or directory

It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

selftests: tc: add 'ct' action kconfig dep

2023-07-18T23:52:12+00:00

When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.

Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final
kconfig.

selftests/tc-testing: Remove configs that no longer exist

2023-06-14T03:49:14+00:00

Some qdiscs and classifiers have recently been retired from kernel.
However, tc-testing config is still cluttered with them which causes noise
when using merge_config.sh script to update existing config for tc-testing
compatibility. Remove the config settings for affected qdiscs and
classifiers.
