selftests/tc-testing: Test case exercising potential mirred redirect deadlock

Add a test case that reproduces deadlock scenario where the user has a drr qdisc attached to root and has a mirred action that redirects to self on egress Signed-off-by: Victor Nogueira Acked-by: Jamal Hadi Salim Link: https://patch.msgid.link/20251210162255.1057663-2-jhs@mojatatu.com Signed-off-by: Paolo Abeni

selftests/tc-testing: Adapt tc police action tests for Gb rounding changes

2025-09-15T23:13:13Z

For the tc police action, iproute2 rounds up mtu and burst sizes to a higher order representation. For example, if the user specifies the default mtu for a police action instance (4294967295 bytes), iproute2 will output it as 4096Mb when this action instance is dumped. After Jay's changes [1], iproute2 will round up to Gb, so 4096Mb becomes 4Gb. With that in mind, fix police's tc test output so that it works both with the current iproute2 version and Jay's.

selftests: tc-testing: fix nat regex matching

2025-04-02T23:34:38Z

In iproute 6.14, the nat ip mask logic was fixed to remove an undefined behaviour[1]. So now instead of reporting '0.0.0.0/32' on x86 and potentially '0.0.0.0/0' in other platforms, it reports '0.0.0.0/0' in all platforms.

tc-tests: Update tc police action tests for tc buffer size rounding fixes.

2025-03-19T17:40:24Z

Before tc's recent change to fix rounding errors, several tests which specified a burst size of "1m" would translate back to being 1048574 bytes (2b less than 1Mb). sprint_size prints this as "1024Kb". With the tc fix, the burst size is instead correctly reported as 1048576 bytes (precisely 1Mb), which sprint_size prints as "1Mb". This updates the expected output in the tests' matchPattern values to accept either the old or the new output.

selftests/tc-testing: require an up to date iproute2 for blockcast tests

2024-03-05T03:30:57Z

Add the dependsOn test check for all the mirred blockcast tests. It will prevent the issue reported by LKFT which happens when an older iproute2 is used to run the current tdc. Tests are skipped if the dependsOn check fails.

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: update test definitions for local resources

2023-09-28T07:51:07Z

With resources localized on a per test basis, some tests definitions either contain redundant commands, were wrong or could be simplified. Update all of them to match the new requirements. Tested-by: Davide Caratti Signed-off-by: Pedro Tammela Acked-by: Jamal Hadi Salim Signed-off-by: Paolo Abeni
