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.

Steven Rostedt be405f95f0 ktest: Add INGORE_ERRORS to ignore warnings in boot up
When testing a kernel that has warnings, ktest.pl will fail the test
when it sees the warning. If you need to test the the kernel and want
to ignore the errors that are produced, the option IGNORE_ERRORS has
been added. When IGNORE_ERRORS is set to something other than 0, it will
ignore call traces due to WARN_ON().

Steven Rostedt 96f6a0df19 ktest: Still do reboot even for REBOOT_TYPE = script
The REBOOT_TYPE may be either grub or script, if it is script
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
for both grub and script.

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.

Steven Rostedt 35ce5952e6 ktest: Add prompt to use OUTPUT_MIN_CONFIG
If the defined OUTPUT_MIN_CONFIG in the make_min_config test exists,
then give a prompt to ask the user if they want to use that config
instead, as it is very often the case, especially when the test has been
interrupted. The OUTPUT_MIN_CONFIG is usually the config that one wants
to use to continue the test where they left off.

But if START_MIN_CONFIG is defined (thus the MIN_CONFIG is not the
default), then do not prompt, as it will be annoying if the user has
this as one of many tests, and the test pauses waiting for input, while
the user is sleeping.

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.

Note, the code from streamline_config (make localmodconfig)
was copied and used to find the dependencies in the Kconfig file.

Steven Rostedt 4c4ab1204f ktest: Add test type make_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.

TODO: add a test version that makes the config do more than just
      boot, like having network access.

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.

Currently the config_bisect compares the min config with the

config it will ignore the options that are set in the good config.

Note: This only ignores the config, it does not (yet) handle
options that are different between the two configs. If the good
config has "SLAB" set and the bad config has "SLUB" it will not
find the bug if the bug had to do with changing these two options.

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}

[etc]

Now we just need to update the variables at the top.

Steven Rostedt 9386c6ab7a ktest: Use oldnoconfig instead of yes command
Running the command "yes ''" through the make oldconfig may enable
things we do not want enabled. If something is default enabled, the
yes command with '' as an argument will enable it.

Use oldnoconfig, which runs everything as if 'no' was used.
