2025-09-15selftests/tc-testing: Adapt tc police action tests for Gb rounding changesVictor Nogueira
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.

2025-04-02selftests: tc-testing: fix nat regex matchingPedro Tammela
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.

2025-03-19tc-tests: Update tc police action tests for tc buffer size rounding fixes.Jonathan Lennox
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.

2019-06-25tc-testing: Restore original behaviour for namespaces in tdcLucas Bates
This patch restores the original behaviour for tdc prior to the introduction of the plugin system, where the network namespace functionality was split from the main script. It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.
