* tc-testing: Restore original behaviour for namespaces in tdcLucas Bates2019-06-251-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'.

* tc-testing: use a plugin to build eBPF programDavide Caratti2018-10-051-0/+2
| | | | | | | | | use a TDC plugin, instead of building eBPF programs in the 'setup' stage. '-B' argument can be used to build eBPF programs in $EBPFDIR directory, in the 'pre-suite' stage. Binaries are then cleaned in 'post-suite' stage. Signed-off-by: Davide Caratti <dcaratti@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* tc: Update README and add configKeara Leibovitz2018-08-111-5/+11
| | | | | | | | | | | | Updated README. Added config file that contains the minimum required features enabled to run the tests currently present in the kernel. This must be updated when new unittests are created and require their own modules. Signed-off-by: Keara Leibovitz <kleib@mojatatu.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* selftests: Introduce tc testsuiteLucas Bates2017-06-201-0/+102
Add the beginnings of a testsuite for tc functionality in the kernel. These are a series of unit tests that use the tc executable and verify the success of those commands by checking both the exit codes and the output from tc's 'show' operation. To run the tests: # cd tools/testing/selftests/tc-testing # sudo ./tdc.py You can specify the tc executable to use with the -p argument on the command line or editing the 'TC' variable in tdc_config.py. Refer to the README for full details on how to run. The initial complement of test cases are limited mostly to tc actions. Test cases are most welcome; see the creating-testcases subdirectory for help in creating them.
