This refactors the selftest Makefiles to extract the test running logic
to be reused between "run_tests" and "emit_tests", while also fixing
up the test output to be TAP version 13 compliant:
- added "plan" line
- fixed result line syntax
- moved all test output to be "# "-prefixed as TAP "diagnostic" lines
The prefixing code includes a fallback mode for limited execution
environments.

selftests: Extract single-test shell logic from lib.mk
selftests: Use runner.sh for emit targets
selftests: Extract logic for multiple test runs
selftests/runner: Add plan line and fix result line syntax
selftests/runner: Distinguish between missing and non-executable
selftests: Move test output to diagnostic lines

In order to improve the reusability of the kselftest test running logic,
this extracts the single-test logic from lib.mk into kselftest/runner.sh
which lib.mk can call directly. No changes in output.
As part of the change, this removes the unused "summary" Makefile variable
(and tests). However, future merging with the "emit_tests" target needs
to be able to redirect output, so a new "logfile" variable is introduced.

Shouldn't the selftests/Makefile need update for "summary" removal??

I didn't see anything using "summary" except as a --summary argument
to the run_kselftests.sh script. Maybe I missed it?

This change is only removing the "kselftest" entry, for which the
target is long gone. Since I was adding a directory by that name, I
needed to remove it from the .gitignore file. I have nothing to do
with the gpio stuff. :)
Thanks for looking this over!

Right: it's used only by the run_kselftest.sh script:
ALL_SCRIPT := $(INSTALL_PATH)/run_kselftest.sh
install:
...
echo "if [ \"\$$1\" = \"--summary\" ]; then" >> $(ALL_SCRIPT)
So, I think this entire series can land. Is there other feedback I
should incorporate? I'd like to see it get some -next testing...
Thanks!

Kees,
Yes I was planning to get this into next and did some testing. I found
that the first patch breaks the summary option.
You can see it by running
make summary=1 TARGETS="breakpoints" kselftest
with and without your first patch. Ca you fix the regression and send
me revised patches. Sorry, I didn't get back to you sooner. A few bugs
I found kept me busy.
While I was testing your patch series, I found test build failures due
to circular dependency that needed fixing. In addition, the same
headers_install dependency, also broke O= and KBUILD_OUTPUT builds
and fixed those as well. Long story short, these fixes might conflict
with your work.
thanks,

I can rebase the series -- which tree should I look at? (Is it all in
-next already?)

This reuses the new runner.sh for the emit targets instead of manually
running each test via run_kselftest.sh.

* [PATCH 2/6] selftests: Use runner.sh for emit targets
@ 2019-04-09 23:55 ` Kees Cook

From: Kees Cook @ 2019-04-09 23:55 UTC (permalink / raw)
This reuses the new runner.sh for the emit targets instead of manually
running each test via run_kselftest.sh.

* [PATCH 4/6] selftests/runner: Add plan line and fix result line syntax

The TAP version 13 spec requires a "plan" line, which has been missing.
Since we always know how many tests we're going to run, emit the count on
the plan line. This also fixes the result lines to remove the "1.." prefix
which is against spec, and to mark skips with the correct "# SKIP" suffix.

If a test was missing (e.g. wrong architecture, etc), the test runner
would incorrectly claim the test was non-executable. This adds an
existence check to report correctly.

* [PATCH 6/6] selftests: Move test output to diagnostic lines
@ 2019-04-09 23:55 ` Kees Cook
0 siblings, 0 replies; 28+ messages in thread
From: keescook @ 2019-04-09 23:55 UTC (permalink / raw)
This changes the selftest output so that each test's output is prefixed
with "# " as a TAP "diagnostic line".
This creates a bit of a kernel-specific TAP dialect where the diagnostics
precede the results. The TAP spec isn't entirely clear about this, though,
so I think it's the correct solution so as to keep interactive runs making
sense. If the output _followed_ the result line in the spec-suggested
YAML form, each test would dump all of its output at once instead of as
it went, making debugging harder.
This does, however, solve the recursive TAP output problem, as sub-tests
will simply be prefixed by "# ". Parsing sub-tests becomes a simple
problem of just removing the first two characters of a given top-level
test's diagnostic output, and parsing the results.
Note that the shell construct needed to both get an exit code from
the first command in a pipe and still filter the pipe (to add the "# "
prefix) uses a POSIX solution rather than the bash "pipefail" option
which is not supported by dash.
Since some test environments may have a very minimal set of utilities
available, the new prefixing code will fall back to doing line-at-a-time
prefixing if perl and/or stdbuf are not available.

From: Kees Cook @ 2019-04-09 23:55 UTC (permalink / raw)
This changes the selftest output so that each test's output is prefixed
with "# " as a TAP "diagnostic line".
This creates a bit of a kernel-specific TAP dialect where the diagnostics
precede the results. The TAP spec isn't entirely clear about this, though,
so I think it's the correct solution so as to keep interactive runs making
sense. If the output _followed_ the result line in the spec-suggested
YAML form, each test would dump all of its output at once instead of as
it went, making debugging harder.
This does, however, solve the recursive TAP output problem, as sub-tests
will simply be prefixed by "# ". Parsing sub-tests becomes a simple
problem of just removing the first two characters of a given top-level
test's diagnostic output, and parsing the results.
Note that the shell construct needed to both get an exit code from
the first command in a pipe and still filter the pipe (to add the "# "
prefix) uses a POSIX solution rather than the bash "pipefail" option
which is not supported by dash.
Since some test environments may have a very minimal set of utilities
available, the new prefixing code will fall back to doing line-at-a-time
prefixing if perl and/or stdbuf are not available.
