2025-07-24T00:52:08Z

Update configuration of tc-tests and preload DualPI2 module for self-tests, and add following self-test cases for DualPI2: Test a4c7: Create DualPI2 with default setting Test 1ea4: Create DualPI2 with memlimit Test 2130: Create DualPI2 with typical_rtt and max_rtt Test 90c1: Create DualPI2 with max_rtt Test 7b3c: Create DualPI2 with any_ect option Test 49a3: Create DualPI2 with overflow option Test d0a1: Create DualPI2 with drop_enqueue option Test f051: Create DualPI2 with no_split_gso option Test 456b: Create DualPI2 with packet step_thresh Test 610c: Create DualPI2 with packet min_qlen_step Test b4fa: Create DualPI2 with packet coupling_factor Test 37f1: Create DualPI2 with packet classic_protection Signed-off-by: Chia-Yu Chang Reviewed-by: Victor Nogueira Link: https://patch.msgid.link/20250722095915.24485-6-chia-yu.chang@nokia-bell-labs.com Signed-off-by: Jakub Kicinski

selftests: tc-testing: Pre-load IFE action and its submodules

2025-04-08T23:15:52Z

Recently we had some issues in parallel TDC where some of IFE tests are failing due to some of IFE's submodules (like act_meta_skbtcindex and act_meta_skbprio) taking too long to load [1]. To avoid that issue, pre-load IFE and all its submodules before running any of the tests in tdc.sh [1] https://lore.kernel.org/netdev/e909b2a0-244e-4141-9fa9-1b7d96ab7d71@mojatatu.com/T/#u Signed-off-by: Victor Nogueira Link: https://patch.msgid.link/20250407215656.2535990-1-victor@mojatatu.com Signed-off-by: Jakub Kicinski

selftests: tc-testing: enable all tdc tests

2024-01-26T00:38:16Z

For the longest time tdc ran only actions and qdiscs tests. It's time to enable all the remaining tests so every user visible piece of TC is tested by the downstream CIs.

net/sched: Retire ipt action

2024-01-02T12:41:16Z

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: remove buildebpf plugin

2023-11-28T02:15:42Z

As tdc only tests loading/deleting and anything more complicated is better left to the ebpf test suite, provide a pre-compiled version of 'action.c' and don't bother compiling it in kselftests or on the fly at all.

selftests: tc-testing: use parallel tdc in kselftests

Leverage parallel tests in kselftests using all the available cpus. We tested this in tuxsuite and locally extensively and it seems it's ready for prime time. Signed-off-by: Pedro Tammela Reviewed-by: Simon Horman Signed-off-by: David S. Miller

selftests: tc-testing: preload all modules in kselftests

2023-11-16T22:30:10Z

While running tdc tests in parallel it can race over the module loading done by tc and fail the run with random errors. So avoid this by preloading all modules before running tdc in kselftests. Signed-off-by: Pedro Tammela Reviewed-by: Simon Horman Signed-off-by: David S. Miller
