Steven Rostedt (Red Hat) 7328735cbf ktest: Remove indexes from warnings check
The index of a line where a warning is tested can be returned
differently on different versions of gcc (or same version compiled
differently). That is, a tab + space can give different results. This
causes the warning check to produce a false positive. Removing the
index from the check fixes this issue.

Steven Rostedt (Red Hat) 4c0b67a27d ktest: Ignore warnings during reboot
The reboot just wants to get to the next kernel. But if a warning (Call
Trace) appears, the monitor will report an error, and the reboot will
think something went wrong and power cycle the box, even though we
successfully made it to the next kernel.

Ignore warnings during the reboot until we get to the next kernel. It
will still timeout if we never get to the next kernel and then a power
cycle will happen. That's what we want it to do.

Steven Rostedt (Red Hat) d684553623 ktest: Search for linux banner for successful reboot
Sometimes when a test kernel passed fine, but on reboot it crashed,
ktest could get stuck and not proceed. This would be frustrating if you
let a test run overnight to find out the next morning that it was stuck
on the first test.

To fix this, I made reboot check for the REBOOT_SUCCESS_LINE. If the
line was not detected, then it would power cycle the box.

What it didn't cover was if the REBOOT_SUCCESS_LINE wasn't defined or if
a 'good' kernel did not display the line. Instead have it search for the
Linux banner "Linux version". The reboot just needs to get to the start
of the next kernel, it does not need to test if the next kernel makes it
to a boot prompt.

After we find the next kernel has booted, then we just wait for either
the REBOOT_SUCCESS_LINE to appear or the timeout.

Steven Rostedt (Red Hat) 4283b169ab ktest: Add make_warnings_file and process full warnings
Although the patchcheck test checks for warnings in the files that were
changed, this check does not catch warnings that were caused by header
file changes and the warnings appear in C files not touched by the
commit.

Add a new option called WARNINGS_FILE. If this option is set, then the
file it points to is read before bulid, and the file should contain a
list of known warnings. If a warning appears in the build, this file is
checked, and if the warning does not exist in this file, then it fails
the build showing the new warning.

If the WARNINGS_FILE points to a file that does not exist, this will
cause any warning in the build to fail.

A new test is also added called "make_warnings_file". This test will
create do a build and record any warnings it finds into the
WARNINGS_FILE. This test is something that can be run before other tests
to build a warnings file of "known warnings", ie, warnings that were
there before your changes.

Steven Rostedt (Red Hat) 04262be3db ktest: Allow a test option to use its default option
Options are allowed to use other options, for example:

  LOG_FILE = ${OUTPUT_DIR}/${MACHINE}.log

where the option LOG_FILE used the options OUTPUT_DIR and MACHINE.

But if a test option were to use a default option, it will not get
substituted:

  OUTPUT_DIR = ${THIS_DIR}/${MACHINE}

  TEST_START
  OUTPUT_DIR = ${OUTPUT_DIR}/t1

For the above test, OUTPUT_DIR will stay literally "${OUTPUT_DIR}/t1"
and not be converted to "${THIS_DIR}/${MACHINE}/t1". When the test runs,
it will pass the ${OUTPUT_DIR} to the shell, which would probaly
interpret it as "", and the output directory will end up as "/t1".

Change the code where if a test option has its own option name in
its defined field, and a default option exists, then substitute the
default option in its place.

Steven Rostedt (Red Hat) 35275685bf ktest: Strip off '\n' when reading which files were modified
The patchcheck test looks at what files are modified for each patch it
checks and makes sure that those files do not produce any warnings.

Unfortunately, when it read the diffstat, the newlines were added on the
files and this made compares miss warnings, and commits that should not
have passed, ktest let pass.

Fix this by using the perl command "chomp" that strips off whitespace at
the end of lines.

Steven Rostedt e1a6c3d748 ktest: Test if target machine is up before install
Sometimes a test kernel will crash or hang on reboot (this is even more
apparent when testing a config without CGROUPS on a box running
systemd). When this happens, on the next iteration of installing a
kernel, ktest will fail when it tries to install.

Have ktest do a check to see if the target can be connected to via ssh
before it tries to install. If it can't connect, then reboot again.
This time the reboot will fail because it can't connect and will force a
power cycle.

Steven Rostedt 1892517056 ktest: Fix breakage from change of oldnoconfig to olddefconfig
Commit fb16d891 "kconfig: replace 'oldnoconfig' with 'olddefconfig', and
keep the old name", changed ktest's default config update from
oldnoconfig to olddefconfig without adding oldnoconfig as a backup.
The make oldnoconfig works much better than its backup of:
   yes '' | make oldconfig

But due to this change, and the fact that ktest is used to build lots of
older kernels (and for bisects), it forgoes the oldnoconfig completely.

Steven Rostedt 7786954c95 ktest: Add native support for syslinux boot loader
I installed Fedora 17 which no longer supports grub v1. I worked
with grub2 for a while, but there's so many issues with it and automated
rebooting, that I decided to switch to syslinux. Instead of using
the REBOOT_SCRIPT and add customized changes to get syslinux booted,
I thought it better to make ktest aware of syslinux and add options
to simplify the use of syslinux on a target test box.

Steven Rostedt 8bc5e4ea3e ktest: Fix ktest confusion with CONFIG_MODULES_USE_ELF_RELA
In order to decide if ktest should bother installing modules on the
target box, it checks if the config file has CONFIG_MODULES=y. But it
also checks if the '=y' part exists. It only will install modules if the
config exists and is set with '=y'. But as the regex that was used
tests:

  /^CONFIG_MODULES(=y)?/

this will also match:

  CONFIG_MODULES_USE_ELF_RELA

as the '=y' part was optional and it did not test the rest of the line.
When this happens, ktest will stop checking the rest of the configs but
it will also think that no modules are needed to be installed. What it
should do is only jump out of the loop if it actually found a
CONFIG_MODULES that is set to true.

Otherwise, ktest wont install the necessary modules needed for proper
booting of the test target.

Steven Rostedt cf79fab676 ktest: Fix config bisect with how make oldnoconfig works
With a name like 'oldnoconfig' one may think that the config generated
would disable all configs that were not defined (selecting "no" for all
options). But this is not the case. It selects the default. If a config
has a 'default y', then it is added if not specified.

This broke the config bisect, because options not specified by a config
will just use the default, where it expected to turn off. This caused an
option to be enabled that disabled an option that would break the build.
The end result was that we never found the bad config at the end of the
test.

Instead of using 'make oldnoconfig', ktest now builds the options it
expects enabled and disabled. When it turns off an option, it will no
longer remove it, but actually set it to:

 # CONFIG_FOO is not set.

The config-bisect can take a bad config and bisect it down to find out
what config actually breaks the config. But as all tests will apply a

can disable configs). The end result is that the config bisect test will
not find a config that breaks. This can be rather frustrating to the
user.

The CONFIG_BISECT_CHECK option, when set to 1, will make sure that the
bad config (with the minconfig applied) still fails before trying to
bisect.

Steven Rostedt 683a3e6481 ktest: Fix kernelrevision with POST_BUILD
The PRE_BUILD and POST_BUILD options of ktest are added to allow the
user to add temporary patch to the system and remove it on builds. This
is sometimes use to take a change from another git branch and add it to
a series without the fix so that this series can be tested, when an
unrelated bug exists in the series.

The problem comes when a tagged commit is being used. For example, if
v3.2 is being tested, and we add a patch to it, the kernelrelease for
that commit will be 3.2.0+, but without the patch the version will be
3.2.0. This can cause problems when the kernelrelease is determined for
creating the /lib/modules directory. The kernel booting has the '+' but
the module directory will not, and the modules will be missing for that
boot, and may not allow the kernel to succeed.

The fix is to put the creation of the kernelrelease in the POST_BUILD
logic, before it applies the POST_BUILD operation. The POST_BUILD is
where the patch may be removed, removing the '+' from the kernelrelease.

The calculation of the kernelrelease will also stay in its current
location but will be ignored if it was already calculated previously.

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.

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.
