[PATCH kunit-fixes v5 1/4] kunit: Support skipped tests

by David Gow

The kunit_mark_skipped() macro marks the current test as "skipped", with the provided reason. The kunit_skip() macro will mark the test as skipped, and abort the test. The TAP specification supports this "SKIP directive" as a comment after the "ok" / "not ok" for a test. See the "Directives" section of the TAP spec for details: https://testanything.org/tap-specification.html#directives The 'success' field for KUnit tests is replaced with a kunit_status enum, which can be SUCCESS, FAILURE, or SKIPPED, combined with a 'status_comment' containing information on why a test was skipped. A new 'kunit_status' test suite is added to test this.

[net-next, v3, 00/10] ptp: support virtual clocks and timestamping

by Yangbo Lu

Current PTP driver exposes one PTP device to user which binds network interface/interfaces to provide timestamping. Actually we have a way utilizing timecounter/cyclecounter to virtualize any number of PTP clocks based on a same free running physical clock for using. The purpose of having multiple PTP virtual clocks is for user space to directly/easily use them for multiple domains synchronization. user space: ^ ^ | SO_TIMESTAMPING new flag: | Packets with | SOF_TIMESTAMPING_BIND_PHC | TX/RX HW timestamps v v +--------------------------------------------+ sock: | sock (new member sk_bind_phc) | +--------------------------------------------+ ^ ^ | ethtool_op_get_phc_vclocks | Convert HW timestamps | | to sk_bind_phc v v +--------------+--------------+--------------+ vclock: | ptp1 | ptp2 | ptpN | +--------------+--------------+--------------+ pclock: | ptp0 free running | +--------------------------------------------+ The block diagram may explain how it works. Besides the PTP virtual clocks, the packet HW timestamp converting to the bound PHC is also done in sock driver. For user space, PTP virtual clocks can be created via sysfs, and extended SO_TIMESTAMPING API (new flag SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock for timestamping. The test tool timestamping.c (together with linuxptp phc_ctl tool) can be used to verify: # echo 4 > /sys/class/ptp/ptp0/n_vclocks [ 129.399472] ptp ptp0: new virtual clock ptp2 [ 129.404234] ptp ptp0: new virtual clock ptp3 [ 129.409532] ptp ptp0: new virtual clock ptp4 [ 129.413942] ptp ptp0: new virtual clock ptp5 [ 129.418257] ptp ptp0: guarantee physical clock free running # # phc_ctl /dev/ptp2 set 10000 # phc_ctl /dev/ptp3 set 20000 # # timestamping eno0 2 SOF_TIMESTAMPING_TX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC # timestamping eno0 2 SOF_TIMESTAMPING_RX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC # timestamping eno0 3 SOF_TIMESTAMPING_TX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC # timestamping eno0 3 SOF_TIMESTAMPING_RX_HARDWARE SOF_TIMESTAMPING_RAW_HARDWARE SOF_TIMESTAMPING_BIND_PHC Changes for v2: - Converted to num_vclocks for creating virtual clocks. - Guranteed physical clock free running when using virtual clocks. - Fixed build warning. - Updated copyright. Changes for v3: - Supported PTP virtual clock in default in PTP driver. - Protected concurrency of ptp->num_vclocks accessing. - Supported PHC vclocks query via ethtool. - Extended SO_TIMESTAMPING API for PHC binding. - Converted HW timestamps to PHC bound, instead of previous binding domain value to PHC idea. - Other minor fixes.

Kernel selftests and backward compatibility?

by Vitaly Chikunov

Shuah, Do kselftests require to be backward-compatible? I see Documentation/dev-tools/kselftest.rst does not require this, but maybe it's assumed like in other test suites (or in perf). | In general, the rules for selftests are | | * Do as much as you can if you're not root; | | * Don't take too long; | | * Don't break the build on any architecture, and | | * Don't cause the top-level "make run_tests" to fail if your feature is | unconfigured. For example LTP says: | LTP test should be as backward compatible as possible. [...] | | Therefore LTP test for more current features should be able to cope with older | systems. Also, (it's said[1]) perf, even though in kernel tree, is supposed to work properly on any (older/newer) version of Linux. Can you clarify this point in kselftest.rst? I think, this would be useful for future kselftests developers, users, and packagers. (Currently, I package for ALT Linux kselftests (and perf) from the latest mainline branch, so people could test even older kernels with the latest kselftests. If there is policy to be backward-compatible kselftests in the future could reach a state where users would run them in all pass mode (without selecting only working tests). This, in turn, would increase [ease of] usability of tests and thus frequency of their run and consequentially quality kernel testing overall. Thanks, [1] https://lkml.org/lkml/2020/7/29/677

[PATCH kunit-next] thunderbolt: test: Reinstate a few casts of bitfields

by David Gow

Partially revert "thunderbolt: test: Remove some casts which are no longer required". It turns out that typeof() doesn't support bitfields, so these still need to be cast to the appropriate enum. The only mention of typeof() and bitfields I can find is in the proposal to standardise them: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2619.htm This was caught by the kernel test robot: https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org/thread/FDKBHAV… Fixes: 8f0877c26e ("thunderbolt: test: Remove some casts which are no longer required") Reported-by: kernel test robot <lkp(a)intel.com> Signed-off-by: David Gow <davidgow(a)google.com> --- Whoops: I didn't notice this was broken earlier.

[PATCH v2] selftests/lkdtm: Use /bin/sh not $SHELL

by Kees Cook

Some environments do not set $SHELL when running tests. There's no need to use $SHELL here anyway, so just replace it with hard-coded path instead. Additionally avoid using bash-isms in the command, so that regular /bin/sh can be used.

[PATCH] selftests/sgx: remove checks for file execute permissions

by Dave Hansen

The SGX selftests can fail for a bunch of non-obvious reasons like 'noexec' permissions on /dev (which is the default *EVERYWHERE* it seems). A new test mistakenly also looked for +x permission on the /dev/sgx_enclave. File execute permissions really only apply to the ability of execve() to work on a file, *NOT* on the ability for an application to map the file with PROT_EXEC. SGX needs to mmap(PROT_EXEC), but doesn't need to execve() the device file. Remove the check.

[PATCH] selftests: icmp_redirect: support expected failures

by Andrea Righi

According to a comment in commit 99513cfa16c6 ("selftest: Fixes for icmp_redirect test") the test "IPv6: mtu exception plus redirect" is expected to fail, because of a bug in the IPv6 logic that hasn't been fixed yet apparently. We should probably consider this failure as an "expected failure", therefore change the script to return XFAIL for that particular test and also report the total amount of expected failures at the end of the run.
