2020-07-17Documentation: kunit: Remove references to --defconfigDavid Gow
The --defconfig option in kunit_tool was removed in [1], but the getting started and kunit_tool documentation still encouraged its use. Update those documents to reflect that it's no-longer required, and is the default behaviour if no .kunitconfig is found. Also update a couple of places where .kunitconfig is still referred to as kunitconfig (this was changed in [2]).

2020-06-04kcov: collect coverage from interruptsAndrey Konovalov
This change extends kcov remote coverage support to allow collecting coverage from soft interrupts in addition to kernel background threads. To collect coverage from code that is executed in softirq context, a part of that code has to be annotated with kcov_remote_start/stop() in a similar way as how it is done for global kernel background threads. Then the handle used for the annotations has to be passed to the KCOV_REMOTE_ENABLE ioctl. Internally this patch adjusts the __sanitizer_cov_trace_pc() compiler inserted callback to not bail out when called from softirq context. kcov_remote_start/stop() are updated to save/restore the current per task kcov state in a per-cpu area (in case the softirq came when the kernel was already collecting coverage in task context). Coverage from softirqs is collected into pre-allocated per-cpu areas, whose size is controlled by the new CONFIG_KCOV_IRQ_AREA_SIZE.

2020-06-02Documentation: kgdboc: Document new kgdboc_earlycon parameterDouglas Anderson
The recent patch ("kgdboc: Add kgdboc_earlycon to support early kgdb using boot consoles") adds a new kernel command line parameter. Document it. Note that the patch adding the feature does some comparing/contrasting of "kgdboc_earlycon" vs. the existing "ekgdboc". See that patch for more details, but briefly "ekgdboc" can be used _instead_ of "kgdboc" and just makes "kgdboc" do its normal initialization early (only works if your tty driver is already ready). The new "kgdboc_earlycon" works in combination with "kgdboc" and is backed by boot consoles.

2020-05-19selftests: introduce gen_tar Makefile targetVeronika Kabatova
The gen_kselftest_tar.sh always packages *all* selftests and doesn't pass along any variables to `make install` to influence what should be built. This can result in an early error on the command line ("Unknown tarball format TARGETS=XXX"), or unexpected test failures as the tarball contains tests people wanted to skip on purpose. Since the makefile already contains all the logic, we can add a target for packaging. Keep the default .gz target the script uses, and actually extend the supported formats by using tar's autodetection. To not break current workflows, keep the gen_kselftest_tar.sh script as it is, with an added suggestion to use the makefile target instead.

2020-04-28kselftest: add fixture variantsJakub Kicinski
Allow users to build parameterized variants of fixtures. If fixtures want variants, they call FIXTURE_VARIANT() to declare the structure to fill for each variant. Each fixture will be re-run for each of the variants defined by calling FIXTURE_VARIANT_ADD() with the differing parameters initializing the structure. Since tests are being re-run, additional initialization (steps, no_print) is also added.

2020-04-13kcsan: Introduce scoped ASSERT_EXCLUSIVE macrosMarco Elver
Introduce ASSERT_EXCLUSIVE_*_SCOPED(), which provide an intuitive interface to use the scoped-access feature, without having to explicitly mark the start and end of the desired scope. Basing duration of the checks on scope avoids accidental misuse and resulting false positives, which may be hard to debug. See added comments for usage. The macros are implemented using __attribute__((__cleanup__(func))), which is supported by all compilers that currently support KCSAN.
