"-j" mode is optional, and works with all existing test selection mechanism, as well as "-v", "-l" etc. In "-j" mode, main process use UDS/SEQPACKET to communicate to each forked worker, commanding it to run tests and collect logs. After all tests are finished, a summary is printed. main process use multiple competing threads to dispatch work to worker, trying to keep them all busy. The test status will be printed as soon as it is finished, if there are error logs, it will be printed after the final summary line. By specifying "--debug", additional debug information on server/worker communication will be printed.

Usually, this is what we want. But a few components in the kernel repository (namely, BPF iterators and selftests) also install bpftool locally before using it. In such a case, bash completion is not necessary and is just a useless build artifact. Let's add an "install-bin" target to bpftool, to offer a way to install the binary only.

One of those ways is to run "make tools/bpf" from the root of the kernel repository. This command builds bpftool, along with the other tools under tools/bpf, and runqslower in particular. After running the command and upon a successful bpftool build, the script attempts to cleanup the generated objects. However, after building with this target and in the case of runqslower, the files are not cleaned up as expected. This is because the "tools/bpf" target sets $(OUTPUT) to .../tools/bpf/runqslower/ when building the tool, causing the object files to be placed directly under the runqslower directory. But when running "cd tools/bpf; make clean", the value for $(OUTPUT) is set to ".output" (relative to the runqslower directory) by runqslower's Makefile, and this is where the Makefile looks for files to clean up. We cannot easily fix in the root Makefile (where "tools/bpf" is defined) or in tools/scripts/Makefile.include (setting $(OUTPUT)), where changing the way the output variables are passed would likely have consequences elsewhere. We could change runqslower's Makefile to build in the repository instead of in a dedicated ".output/", but doing so just to accommodate a test script doesn't sound great. Instead, let's just make sure that we clean up runqslower properly by adding the correct command to the script. This will attempt to clean runqslower twice: the first try with command "cd tools/bpf; make clean" will search for tools/bpf/runqslower/.output and fail to clean it (but will still clean the other tools, in particular bpftool), the second one (added in this commit) sets the $(OUTPUT) variable like for building with the "tool/bpf" target and should succeed.

| | * | | | | | | | tools/runqslower: Install libbpf headers when buildingQuentin Monnet2021-10-081-6/+9

Instead, they should be exported with "make install_headers". Let's make sure that runqslower installs the headers properly when building. We use a libbpf_hdrs target to mark the logical dependency on libbpf's headers export for a number of object files, even though the headers should have been exported at this time (since bpftool needs them, and is required to generate the skeleton or the vmlinux.h). When descending from a parent Makefile, the specific output directories for building the library and exporting the headers are configurable with BPFOBJ_OUTPUT and BPF_DESTDIR, respectively. This is in addition to OUTPUT, on top of which those variables are constructed by default. Also adjust the Makefile for the BPF selftests. We pass a number of variables to the "make" invocation, because we want to point runqslower to the (target) libbpf shared with other tools, instead of building its own version. In addition, runqslower relies on (target) bpftool, and we also want to pass the proper variables to its Makefile so that bpftool itself reuses the same libbpf.

The Makefile for bpftool exposes these objects by adding tools/lib as an include directory ("-I$(srctree)/tools/lib"). This is a working solution, but this is not the cleanest one. The risk is to involuntarily include objects that are not intended to be exposed by the libbpf. The headers needed to compile bpftool should in fact be "installed" from libbpf, with its "install_headers" Makefile target. In addition, there is one header which is internal to the library and not supposed to be used by external applications, but that bpftool uses anyway. Adjust the Makefile in order to install the header files properly before compiling bpftool. Also copy the additional internal header file (nlattr.h), but call it out explicitly. Build (and install headers) in a subdirectory under bpftool/ instead of tools/lib/bpf/. When descending from a parent Makefile, this is configurable by setting the OUTPUT, LIBBPF_OUTPUT and LIBBPF_DESTDIR variables. Also adjust the Makefile for BPF selftests, so as to reuse the (host) libbpf compiled earlier and to avoid compiling a separate version of the library just for bpftool.

But in our kernel build, the __htab_map_lookup_elem gets inlined within the htab_map_lookup_elem, so it's not trigered and the test fails. Fixing this by using htab_map_delete_elem, which is not inlined for bpf_prog calls (like htab_map_lookup_elem is) and is used directly as pointer for map_delete_elem, so it won't disappear by inlining.

This also introduces a couple of test cases to verifier selftests for validating whether we get an error or not depending on if invalid kfunc call remains after elimination of unreachable instructions.

The current test infra introduces a bit of jitter in test runtime, due to multiple explicit delays. Additionally the runtime is measured by the shell script wrapper. On a slow VM, the script overhead is measurable and subject to relevant jitter. One solution to make the test more stable would be adding more slack to the expected time; that could possibly hide real regressions. Instead move the measurement inside the command doing the transfer, and drop most unneeded sleeps.

These tests are however done in a somewhat impenetrable manner by directly comparing PCI IDs against a blacklist or a whitelist, and bailing out silently if the machine is not compatible. Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying the supported machines in a human-readable manner. If the current machine is incompatible, the helper emits a SKIP message and returns an error code, based on which the caller can gracefully bail out in a suitable way. This allows a more readable conditions such as: mlxsw_only_on_spectrum 2+ || return Convert all existing open-coded guards to the new helper. Also add two new guards to do_mark_test() and do_drop_test(), which are supported only on Spectrum-2+, but the corresponding check was not there.

Still the system admin and/or the application have to opt-in to MPTCP explicitly. After that, they need to change (increase) the default maximum number of additional subflows. Let set that to reasonable default, and make end-users life easier. Additionally we need to update some self-tests accordingly.

The test splits install_qdisc() into its constituents, install_root_qdisc() and install_qdisc_tcX(). This is in order to test that when mirroring is enabled on one TC, the other TC does not mirror.
