Linus Torvalds 586c6e7013 While demoing ktest at ELC in 2012, it was embarrassing that the
make_min_config test failed to work because the snowball board I was tesing
 it against had a config that would not build. But the make_min_config
 only tested the testing part and ignored build failures. The end result
 was a config file that would not boot.
 
 This time, for real.

Steven Rostedt bf1c95abaf ktest: Fix make_min_config test when build fails
The make_min_config does not take into account when the build fails,
resulting in a invalid MIN_CONFIG .config file. When the build fails,
it is ignored and the boot test is executed, using the previous built
kernel. The configs that should be tested are not tested and they may
be added or removed depending on the result of the last kernel that
succeeded to be built.

If the build fails, mark the current config as a failure and the
configs that were disabled may still be needed.

Frederic Weisbecker 85bbddc37b selftests: new x86 breakpoints selftest
Bring a first selftest in the relevant directory.  This tests several
combinations of breakpoints and watchpoints in x86, as well as icebp traps
and int3 traps.  Given the amount of breakpoint regressions we raised
after we merged the generic breakpoint infrastructure, such selftest
became necessary and can still serve today as a basis for new patches that
touch the do_debug() path.

Bring a new kernel selftests directory in tools/testing/selftests.  To
add a new selftest, create a subdirectory with the sources and a
makefile that creates a target named "run_test" then add the
subdirectory name to the TARGET var in tools/testing/selftests/Makefile
and tools/testing/selftests/run_tests script.

This can help centralizing and maintaining any useful selftest that
developers usually tend to let rust in peace on some random server.

it is expected that a REBOOT_SCRIPT is defined.

With the SWITCH_TO_TEST which is the complement of SWITCH_TO_GOOD,
which does basically the same thing as REBOOT_SCRIPT and but for
both grub and script, the REBOOT_SCRIPT does not need to be mandatory
anymore.

Do not require the REBOOT_SCRIPT and always run the reboot code

Steven Rostedt 9cc9e091ed ktest: Detect typos in option names
It becomes quite annoying when you go to run a test and then
realize that you typed an option name wrong, and the test starts
doing the default action and not what you expected it to do.

It is even more annoying when you wake up the next day after
running the test over night when you discover this.

By testing if all options specified in a config file are
used by either ktest or were used in one of the option's values
we can see if there are any dangling options that were not used.
In such a case, show the user the options that were not used
and ask them if they want to continue or not.

The option IGNORE_UNUSED was also added to allow the user to
override this feature.

Steven Rostedt c5dacb88f0 ktest: Allow overriding bisect test results
When running the ktest git bisect test, if the BISECT_TYPE is "test",
the bisect is determined to be good or bad based off of the error
code of the test that is run. Currently, if the test returns 0,
it is considered a pass (good), a non-zero is considered a fail (bad).

But it has been requested to add more options, and also change
the meanings of the error codes of the test. For example, one may
want the test to detect if the commit is not good or bad,
(maybe the bisect came to a point where the code in question
does not exist). The test could report an error code that should tell
ktest to skip the commit.

Also, a test could detect that something is horribly wrong and the
biscet should just be aborted.

The new options:

 BISECT_RET_GOOD
 BISECT_RET_BAD
 BISECT_RET_SKIP
 BISECT_RET_ABORT
 BISECT_RET_DEFAULT

have been added. The first 4 take an integer value that will
represent if the test should be considered a pass, fail, neither
good nor bad, or abort respectively.

The BISECT_RET_DEFAULT will bo whatever is not defined by the
above codes. If only BISECT_RET_DEFAULT is defined, then all tests
will do the default.

Steven Rostedt 250bae8be0 ktest: Fix bug when ADD_CONFIG is set but MIN_CONFIG is not
The MIN_CONFIG is a single config that is considered to have all the
configs that are required to boot the box.

ADD_CONFIG is a list of configs that we add that may contain configs
known to be broken (set off) or just configs that we want every box to
have and this can include shared configs.

If a config has no MIN_CONFIG defined, but has multiple files defined
for the ADD_CONFIG, the test will die, because the MIN_CONFIG will
default to ADD_CONFIG. The problem is the code to open MIN_CONFIG
expects a string of one file, not multiple, and the open will fail.

Since the real minconfig that is used is a concatination of MIN_CONFIG
and ADD_CONFIG files, we change the code to open that instead of
whatever MIN_CONFIG defaults to.

kconfig scripts and not something that we found must be enabled to boot
our machine. By keeping the configs that are forced on by default,
separate from the configs we found that are required to boot the box, we
can get a much more interesting IGNORE_CONFIG. In fact, the
IGNORE_CONFIG can usually end up being the must have configs to boot,
and only have 6 or 7 configs set.

Steven Rostedt b9066f6c0e ktest: Use Kconfig dependencies to shorten time to make min_config
To save time, the test does not just grab any option and test
it. The Kconfig files are examined to determine the dependencies
of the configs. If a config is chosen that depends on another
config, that config will be checked first. By checking the
parents first, we can eliminate whole groups of configs that
may have been enabled.

For example, if a USB device config is chosen and depends on
CONFIG_USB, the CONFIG_USB will be tested before the device.
If CONFIG_USB is found not to be needed, it, as well as all
configs that depend on it, will be disabled and removed from
the current min_config.

After doing a make localyesconfig, your kernel configuration may
not be the most useful minimum configuration. Having a true minimum
config that you can use against other configs is very useful if
someone else has a config that breaks on your code. By only forcing
those configurations that are truly required to boot your machine
will give you less of a chance that one of your set configurations
will make the bug go away. This will give you a better chance to
be able to reproduce the reported bug matching the broken config.

Note, this does take some time, and may require you to run the
test over night, or perhaps over the weekend. But it also allows
you to interrupt it, and gives you the current minimum config
that was found till that time.

Note, this test automatically assumes a BUILD_TYPE of oldconfig
and its test type acts like boot.

Steven Rostedt ecaf8e5213 ktest: Have wait on stdio honor bug timeout
After a bug is found, the STOP_AFTER_FAILURE timeout is used to
determine how much output should be printed before breaking out
of the monitor loop. This is to get things like call traces and
enough infromation about the bug to help determine what caused it.

The STOP_AFTER_FAILURE is usually much shorter than the TIMEOUT
that is used to determine when to quit after no more stdio is given.

But since the stdio read uses a wait on I/O, the STOP_AFTER_FAILURE is
only checked after we get something from I/O. But if the I/O does
not return any more data, we wait the TIMEOUT period instead, even
though we already triggered a bug report.

The wait on I/O should honor the STOP_AFTER_FAILURE time if a bug has
been found.

Steven Rostedt f1a5b96219 ktest: Add detection of triple faults
When a triple fault happens in a test, no call trace nor panic
is displayed. Instead, the system reboots to the good kernel.
Since the good kernel may display a boot prompt that matches the
success string, ktest may think that the test succeeded, when it
did not.

Detecting triple faults is tricky because it is hard to generalize
what a reboot looks like. The best that we can come up with for now
is to examine the Linux banner. If we detect that the Linux banner
matches the test we want to test, then look to see if we hit another
Linux banner with a different kernel is booted. This can be assumed
to be a triple fault.

We can't just check for two Linux banners because things like
early printk may cause the Linux banner to be displayed twice. Checking
for different kernel versions should be the safe bet.

If this for some reason detects a false triple boot. A new ktest
config option is also created:

 DETECT_TRIPLE_FAULT

This can be set to 0 to disable this checking.

Steven Rostedt 77d942ceac ktest: Create variables for the ktest config files
I found that I constantly reuse information for each test case.
It would be nice to just define a variable to reuse.

For example I may have:

TEST_START
[...]
TEST = ssh root@mybox /path/to/my/script

TEST_START
[...]
TEST = ssh root@mybox /path/to/my/script

[etc]

The issue is, I may wont to change that script or one of the other
fields. Then I need to update each line individually.

With the addition of config variables (variables only used during parsing
the config) we can simplify the config files. These variables can
also be defined multiple times and each time the new value will
overwrite the old value.

The convention to use a config variable over a ktest option is to use :=
instead of =.

Now we could do:

USER := root
TARGET := mybox
TEST_SCRIPT := /path/to/my/script
TEST_CASE := ${USER}@${TARGET} ${TEST_SCRIPT}

TEST_START
[...]
TEST = ${TEST_CASE}

TEST_START
[...]
TEST = ${TEST_CASE}

Steven Rostedt 10abf118f0 ktest: Start failure timeout on panic too
Currently we just look for a Call Trace to start the time out
when to reboot the box. But if the kernel panics and does not
show a Call Trace, the test will not reboot the box after
the specified timeout.

Steven Rostedt 8d1491bae7 ktest: Ask for the manditory config options instead of just failing
In keeping with the notion that all tools should be simple for
all to use. I've changed ktest.pl to ask for mandatory options
instead of just failing. It will append (or create) the options
the user types in, onto the config file.

During the config_bisect, in case of failure, it is nice to have
the last good and bad .configs that were used. This would let
us restart the config_bisect from those configs.

Copy the last good config into the output dir as config_good,
and the last bad config as config_bad.

Steven Rostedt 1c8a617a27 ktest: Added force stop after success and failure
Added the options STOP_AFTER_SUCCESS and STOP_AFTER_FAILURE to
allow the user to give a time (in seconds) to stop the monitor
after a stack trace or login has been detected. Sometimes the
kernel constantly prints out to the console and this may cause
the test to run indefinitely.

Steven Rostedt cccae1a62a ktest: Parse off the directory name in useconfig for failures
When we store failures, we create a directory that has the build_type

file it uses. This unfortunately gets its own directory on failure.

Added the ability to do a config_bisect. It starts with a bad
config and does the following loop.

	Enable half the configs.
	if none of the configs to check are not enabled
	 (caused by missing dependencies) enable the other half.
	Run the test
	if the test passes, remove the configs from the check
	  but enabled them for further tests (to satisfy
	  dependencies).
	else
	  Remove any config that was not enabled, as we have found
	  a new config that can cause a failure.
	loop till we have only one config left.

Steven Rostedt a57419b366 ktest: New TEST_START instead of using [], and use real SHA1s
Change the config to use TEST_START where the options after a
TEST_START automatically get the [] as it is read and they do
not need to exist in the config file;

TEST_START
MIN_CONFIG = myconfig

is the same as

MIN_CONFIG[1] = myconfig

The benefit is that you no longer need to keep track of test numbers
with tests.

Also process the commit ids that are passed to the options
to get the actually SHA1 so it is no longer relative to the branch.
Ie, saying HEAD will get the current SHA1 and then that will
be used, and will work even if another branch is checked out.
