Steven Rostedt 648a182c61 ktest: Allow a test to override REBOOT_ON_SUCCESS
The option REBOOT_ON_SUCCESS is global, and will have the machine reboot
the the box if all tests are successful. But a test may not want the
machine to reboot, and perhaps have the kernel it loaded be used to
install the next kernel. Or the last test may set up a kernel that the
user may want to look at. In this case, the user could have the global
option REBOOT_ON_SUCCESS be true, but if a test is defined to run at the
end, that test can override the global option and keep the kernel it
installed for the user to log in with.

Steven Rostedt 769df641cc ktest: Fix SWITCH_TO_GOOD to also reboot the machine
When the option SWITCH_TO_GOOD is set, it will be called when the system
needs to reboot to the good server. But currently, this keeps the reboot
from happening. The SWITCH_TO_GOOD is just a way to get to a new kernel,
it may not mean to not reboot.

Steven Rostedt 02ad261704 ktest: Add SCP_TO_TARGET_INSTALL option
Currently the option used to scp both the modules to the target as well
as the kernel image are the same (SCP_TO_TARGET). But some embedded
boards may require them to be different. The modules may need to be put
directly on the board, but the kernel image may need to go to a
tftpserver.

Add the option SCP_TO_TARGET_INSTALL that will allow the user to change
the config so that they may have the modules and image got to different
machines.

Steven Rostedt 6ca996cc7c ktest: Add warning when bugs are ignored
When IGNORE_ERRORS is set, ktest will not fail a test if a backtrace
is detected. But this can be an issue if the user added it in the
config but forgot to remove it. They may be left wondering why their
test did not fail, or even worse, why their bisect gave the wrong
commit.

Add a warning in the output if IGNORE_WARNINGS is set, and ktest detects
a kernel error.

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.

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 c54367f9d6 ktest: Do not opencode reboot in grub setting
When setting the next kernel to boot to with grub, do not opencode
the reboot operation.  The normal reboot operation can be modified by
config options (namely POWERCYCLE_AFTER_REBOOT). This needs to affect
all reboots. Remove the opencoded reboot to make sure that any changes
to the reboot code also affect all reboots.

Steven Rostedt 8d735212e4 ktest: Add processing of complex conditionals
The IF statements for DEFAULTS and TEST_START sections now handle
complex statements (&&,||)

Example:

  TEST_START IF (DEFINED ALL_TESTS || ${MYTEST} == boottest) && ${MACHINE} == gandalf

Steven Rostedt a9f84424be ktest: Fix parsing of config section lines
The order for some of the keywords on a section line
(TEST_START or DEFAULTS) does not really matter. Simply need
to remove the keyword from the line as we process it and
evaluate the next keyword in the line. By removing the keywords
as we find them, we do not need to keep track of where on the
line they were found.

Steven Rostedt ac6974c76e ktest: Sort make_min_config configs by dependecies
The make_min_config test will turn off one config at a time and check
if the config boots or not, and if it does, it will remove that config
plus any config that depended on that config.

ktest already looks if a config has a dependency and will try the
dependency config first. But by sorting the configs and trying the
config with the most configs dependent on it, we can shrink the
minconfig faster.

a variable or option has not been defined.

Steven Rostedt 3d1cc41432 ktest: Add OVERRIDE keyword to DEFAULTS section
The OVERRIDE keyword will allow options defined in the given
DEFAULTS section to override options defined in previous DEFAULT
sections.

Normally, options will error if they were previous defined.
The OVERRIDE keyword allows options that have been previously
defined to be changed in the given section.

Note, the same option can not be defined in the same DEFAULT section
even if that section is marked as OVERRIDE.

Steven Rostedt ab7a3f52ce ktest: Let IF keyword take comparisons
Allow ==, !=, <=, >=, <, and > to be used in IF statements
to compare if a section should be processed or not.

For example:

BITS := 32

DEFAULTS IF ${BITS} == 32
MIN_CONFIG = ${CONFIG_DIR}/config-32
ELSE
MIN_CONFIG = ${CONFIG_DIR}/config-64

Steven Rostedt 45d73a5d8a ktest: Add IF and ELSE to config sections
Add IF keyword to sections within the config. Also added an ELSE
keyword that allows different config options to be set for a given
section.

For example:

TYPE := 1
STATUS := 0

DEFAULTS IF ${TYPE}
[...]
ELSE IF ${STATUS}
[...]
ELSE
[...]

The above will process the first section as $TYPE is true. If it
was false, it would process the last section as $STATUS is false.
