Subject: selftests/ftrace: Add --stop-fail hidden option for debug

Add --stop-fail option for debugging the ftracetest.

With this option, ftracetest stops right after a testcase
fails instead of finish running all testcases.

Subject: selftests/ftrace: Add --console hidden option

Add --console hidden option for debug test cases.

This option allows to put "sh" or something else
when the test case hits a bug.

For example, if you find a testcase which doesn't
pass, you can insert sh for interactive debug as below

  -----
  #!/bin/sh
  # description: sample test case

  good-command
  suspicious-wrong-command
  sh # <- add this for interactive debug

Subject: selftests/ftrace: Remove unneeded per-test init/cleanup ftrace

Since ftracetest framework calls initialize_ftrace() right before
each test and after all tests, we don't need to init/cleanup
ftrace for each test case.
Just remove such unneeded init/cleanup code because it can
increase logfile size.

Subject: selftests/ftrace: Fix to test kprobe $comm arg only if available

Test $comm in kprobe-event argument syntax testcase
only if it is supported on the kernel because
$comm has been introduced 4.8 kernel.
So on older stable kernel, it should be skipped.

we can not resolve the localhost.

Subject: selftests/ftrace: Improve kprobe on module testcase to load/unload
 module

Improve kprobe events on module testcase to check module
load/unload with disabled/enabled events. This also change
the target module to trace_printk.ko, so it depends on
CONFIG_SAMPLE_TRACE_PRINTK=m.

Subject: selftests/ftrace: Test kprobe-event argument with various bitsize

Improve the kprobe-event with argument types testcase
to test it with various bitsize.
kprobe-event argument can be recorded in given types with
various bitsize (8, 16, 32, 64), thus the type testcase
should test the different bitsize too.

Subject: selftests: watchdog: fix message when /dev/watchdog open fails

When /dev/watchdog open fails, watchdog exits with "watchdog not enabled"
message. This is incorrect when open fails due to insufficient privilege.

Fix message to clearly state the reason when open fails with EACCESS when
a non-root user runs it.

Subject: selftests: watchdog: Fix ioctl SET* error paths to take oneshot exit
 path

When ioctls for WDIOC_SETOPTIONS (WDIOS_DISABLECARD or WDIOS_ENABLECARD),
WDIOC_SETTIMEOUT, and WDIOC_SETPRETIMEOUT fail, the error path continues
to handler watchdog timer until user terminates it. When ioctl returns
error, it might not be safe to let the watchdog tick. The error could be
due an unsupported ioctl command or some other error.

Fix it to handle error paths as oneshot to stop the watchdog ticks and
exit right away.

Subject: selftests: gpio: restructure Makefile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch cleans up the Makefile by restructuring a couple of
things, namely:
1) change explicit paths in targets for variables
2) substitute a variable (BINARIES) for another, part of the
   selftests build system (TEST_PROGS_EXTENDED)
3) proper cleaning up of the EXTRA objects

The resulting Makefile is much more readable and manageable.

Subject: selftests: gpio: Fix OUTPUT directory in Makefile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When simply running `make' from the selftests top dir, this
error shows up:

  cc -O2 -g -std=gnu99 -Wall -I../../../../usr/include/ -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/uuid    gpio-mockup-chardev.c ../../../gpio/gpio-utils.o  -lmount -o gpio-mockup-chardev
  cc: error: ../../../gpio/gpio-utils.o: No such file or directory
  <builtin>: recipe for target 'gpio-mockup-chardev' failed
  make[1]: *** [gpio-mockup-chardev] Error 1

because the output directory is set to "selftests/gpio" and
all binaries built from ../../../gpio/ end up there. In fact,
they appear as, exempli gratia:
* gpiogpio-event-mon
* gpiogpio-hammer
* gpioinclude/
* gpiolsgpio
which is wrong, as it's missing a directory separator
somewhere.

This patch sets straight the output directory when building
../../../gpio/ so that binaries don't cross paths.

Subject: selftests/ftrace: Add color to the PASS / FAIL results

Now that ftracetest has over 80 tests, it is difficult to simply scroll
up the console window to find the failed tests when it reports just two
tests have failed. In order to make this stand out better, have the
color of the word "PASS" be green, "FAIL" and "XFAIL" be red, and all
other results be blue. This helps tremendously in quickly spotting the
failed tests by just scrolling up the console window.

Subject: selftests/ftrace: Use colored output when available
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If test is being directly executed (with stdout opened on the
terminal) and the terminal capabilities indicate enough
colors, then use the existing scheme of green, red, and blue
to show when tests pass, fail or end in a different way.

When running the tests redirecting the stdout, for instance,
to a file, then colors are not shown, thus producing a more
readable output.
