* tc-testing: fix the -l argument bug in tdc.pyLucas Bates2017-10-151-4/+4
| | | | | | | | | | This patch fixes a bug in the tdc script, where executing tdc with the -l argument would cause the tests to start running as opposed to listing all the known test cases.

* tc-testing: Split test case files into smaller chunksLucas Bates2017-10-156-1212/+1194Star
| | | | | | | | | | | The original submission had the test cases stored in one monolithic file. This can be unwieldy to edit, especially as more test cases are added. This patch removes the original tests.json file in favour of individual ones broken down by category.

| | * selftests: timers: set-timer-lat: Fix hang when testing unsupported alarmsShuah Khan2017-09-251-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When timer_create() fails on a bootime or realtime clock, setup_timer() returns 0 as if timer has been set. Callers wait forever for the timer to expire. This hang is seen on a system that doesn't have support for: CLOCK_REALTIME_ALARM ABSTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] Test hangs waiting for a timer that hasn't been set to expire. Fix setup_timer() to return 1, add handling in callers to detect the unsupported case and return 0 without waiting to not fail the test. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | do_timer_oneshot() uses select() as a timer with FD_SETSIZE and readfs is cleared with FD_ZERO without FD_SET. When stdout and stderr are redirected, the test hangs in select forever. Fix the problem calling select() with readfds empty and nfds zero. This is sufficient for using select() for timer. With this fix "./set-timer-lat > /dev/null 2>&1" no longer hangs.

* | | bpf: Swap the order of checking prog_info and map_infoMartin KaFai Lau2017-09-291-28/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch swaps the checking order. It now checks the map_info first and then prog_info. It is a prep work for adding test to the newly added fields (the map_ids of prog_info field in particular).

* | | bpf: libbpf: Provide basic API support to specify BPF obj nameMartin KaFai Lau2017-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the libbpf to provide API support to allow specifying BPF object name. In tools/lib/bpf/libbpf, the C symbol of the function and the map is used. Regarding section name, all maps are under the same section named "maps". Hence, section name is not a good choice for map's name. To be consistent with map, bpf_prog also follows and uses its function symbol as the prog's name. This patch adds logic to collect function's symbols in libbpf. There is existing codes to collect the map's symbols and no change is needed. The bpf_load_program_name() and bpf_map_create_name() are added to take the name argument. For the other bpf_map_create_xxx() variants, a name argument is directly added to them. In samples/bpf, bpf_load.c in particular, the symbol is also used as the map's name and the map symbols has already been collected in the existing code. For bpf_prog, bpf_load.c does not collect the function symbol name. We can consider to collect them later if there is a need to continue supporting the bpf_load.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add various test_verifier selftests, and a simple xdp/tc functional test that is being attached to veths. Also let new versions of clang use the recently added -mcpu=probe support [1] for the BPF target, so that it can probe the underlying kernel for BPF insn set extensions. We could also just set this options always, where older versions just ignore it and give a note to the user that the -mcpu value is not supported, but given emitting the note cannot be turned off from clang side lets not confuse users running selftests with it, thus fallback to the default generic one when we see that clang doesn't support it. Also allow CPU option to be overridden in the Makefile from command line.
