Hi all,
Both tc_links.c and tc_opts.c do their tests on the loopback interface. It prevents from parallelizing their executions.
Add a new behaviour to the test_progs framework that creates and opens a new network namespace to run a test in it. This is done automatically on tests whose names start with 'ns_'.
One test already has a name starting with 'ns_', so PATCH 1 renames it to avoid conflicts. PATCH 2 introduces the test_progs 'feature'. PATCH 3 & 4 convert some tests to use these dedicated namespaces.
Signed-off-by: Bastien Curutchet (eBPF Foundation) bastien.curutchet@bootlin.com --- Changes in v2: - Handle the netns creation / opening directly in test_progs - Link to v1: https://lore.kernel.org/bpf/e3838d93-04e3-4e96-af53-e9e63550d7ba@bootlin.com
