When testing a series of commits that also includes changes to the Linux
tools directory, it is useless to test the changes in tools as they may
not affect the kernel itself. Doing tests on the kernel for changes that
do not affect the kernel is a waste of time.
Add a PATCHCHECK_SKIP that takes a series of shas that will be skipped
while doing the individual commit tests.
For example, the runtime verification may have a series of commits like:
$ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD
3d3800b4f7f4 rv: Remove rv_reactor's reference counter
3d3c376118b5 rv: Merge struct rv_reactor_def into struct rv_reactor
24cbfe18d55a rv: Merge struct rv_monitor_def into struct rv_monitor
b0c08dd5348d rv: Remove unused field in struct rv_monitor_def
58d5f0d437a8 (debiantesting-x86-64/trace/rv/core) rv: Return init error when registering monitors
560473f2e2d7 verification/rvgen: Organise Kconfig entries for nested monitors
9efcf590827c tools/dot2c: Fix generated files going over 100 column limit
1160ccaf772f tools/rv: Stop gracefully also on SIGTERM
f60227f34489 tools/rv: Do not skip idle in trace
f3735df6281e verification/rvgen: Do not generate unused variables
6fb37c2a27eb verification/rvgen: Generate each variable definition only once
8cfcf9b0e92f verification/rvgen: Support the 'next' operator
fac5493251a6 rv: Allow to configure the number of per-task monitor
Where the first commit touches the kernel followed by a series of commits
that do not, and ends with commits that do. Instead of having to add
multiple patchcheck tests to handle the gaps, just include the commits
that should not be tested:
$ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD |
grep -e verification -e tools/ | cut -d' ' -f1 |
while read a ; do echo -n "$a "; done
560473f2e2d7 9efcf590827c 1160ccaf772f f60227f34489 f3735df6281e 6fb37c2a27eb 8cfcf9b0e92f
Then set PATCHCHECK_SKIP to that, and those commits will be skipped.
PATCHCHECK_SKIP = 560473f2e2d7 9efcf590827c 1160ccaf772f f60227f34489 f3735df6281e 6fb37c2a27eb 8cfcf9b0e92f

As ktest.pl can run in various different directories, to make sure the
test is running in the proper directory with the proper source and proper
destination directory, display the content of BUILD_DIR and OUTPUT_DIR at
the start of every test.
This can be helpful for the test runner to stop the test if a test is
running in the wrong location instead of finding out after the test has
completed.

If a default variable contains itself, do not recurse on it.
For example:
ADD_CONFIG := ${CONFIG_DIR}/temp_config
DEFAULTS
ADD_CONFIG = ${CONFIG_DIR}/default_config ${ADD_CONFIG}
The above works because the temp variable ADD_CONFIG (is a temp because it
is created with ":=") is already defined, it will be substituted in the
variable option. But if it gets commented out:
# ADD_CONFIG := ${CONFIG_DIR}/temp_config
DEFAULTS
ADD_CONFIG = ${CONFIG_DIR}/default_config ${ADD_CONFIG}
Then the above will go into a recursive loop where ${ADD_CONFIG} will
get replaced with the current definition of ADD_CONFIG which contains the
${ADD_CONFIG} and that will also try to get converted. ktest.pl will error
after 100 attempts of recursion and fail.
When replacing a variable with the default variable, if the default
variable contains itself, do not replace it.

Add -D option that lets the user override options in the config.
For instance, if the config has: BUILD_NOCLEAN=1 which prevents mrproper
from being called before builds, and the user wants to call it once. The
user can run:
ktest -D BUILD_NOCLEAN=0 config
And the default "BUILD_NOCLEAN" options will be disabled.
If the user wants to change the second test to do a build and not boot,
the user can run:
ktest -D 'TEST_TYPE[2]=build' config
Where the '[#]' is for the test to assign the variable for. In the above
example, it will happen on test 2.

In the case of a test that uses the special option ${KERNEL_VERSION} in one
of its settings but has no configuration available in ${OUTPUT_DIR}, for
example if it's a new empty directory, then the `make kernelrelease` call
will fail and the subroutine will chomp an empty string, silently. Fix that
by adding an empty configuration and retrying.

Some distros have grub2 config files with the lines
if [ x"${feature_menuentry_id}" = xy ]; then
menuentry_id_option="--id"
else
menuentry_id_option=""
fi
which match the skip regex defined for grub2 in get_grub_index():
$skip = '^\s*menuentry';
These false positives cause the grub number to be higher than it
should be, and the wrong kernel can end up booting.
Grub documents the menuentry command with whitespace between it and the
title, so make the skip regex reflect this.

The test type "make_warnings_file" should have no mandatory configuration
parameters other than the ones required by the "build" test type, because
its purpose is to create a file with build warnings that may or may not be
used by other subsequent tests. Currently, the only way to use it as a
stand-alone test is by setting POWER_CYCLE, CONSOLE, SSH_USER,
BUILD_TARGET, TARGET_IMAGE, REBOOT_TYPE and GRUB_MENU.

There is a disconnect between the run_command function and the
wait_for_input. The wait_for_input has a default timeout of 2 minutes. But
if that happens, the run_command loop will exit out to the waitpid() of
the executing command. This fails in that it no longer monitors the
command, and also, the ssh to the test box can hang when its finished, as
it's waiting for the pipe it's writing to to flush, but the loop that
reads that pipe has already exited, leaving the command stuck, and the
test hangs.
Instead, make the default "wait_for_input" of the run_command infinite,
and allow the user to override it if they want with a default timeout
option "RUN_TIMEOUT".
But this fixes the hang that happens when the pipe is full and the ssh
session never exits.

In the "reboot" command, it does a check of the machine to see if it is
still alive with a simple "ssh echo" command. If it fails, it will assume
that a normal "ssh reboot" is not possible and force a power cycle.
In this case, the "start_monitor" is executed, but the "end_monitor" is
not, and this causes the screen will not be given back to the console. That
is, after the test, a "reset" command needs to be performed, as "echo" is
turned off.

grub2 has submenus where to use grub-reboot, it requires:
grub-reboot X>Y
where X is the main index and Y is the submenu. Thus if you have:
menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ...
[...]
}
submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ...
menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ...
[...]
}
menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ...
[...]
}
menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ...
[...]
}
And wanted to boot to the "Linux test" kernel, you need to run:
# grub-reboot 1>2
As 1 is the second top menu (the submenu) and 2 is the third of the sub
menu entries.
Have the grub.cfg parsing for grub2 handle such cases.

After a full run of a make_min_config test, I noticed there were a lot of
CONFIGs still enabled that really should not be. Looking at them, I
noticed they were all defined as "default y". The issue is that the test
simple removes the config and re-runs make oldconfig, which enables it
again because it is set to default 'y'. Instead, explicitly disable the
config with writing "# CONFIG_FOO is not set" to the file to keep it from
being set again.
With this change, one of my box's minconfigs went from 768 configs set,
down to 521 configs set.

bootconfig is a new feature that appends scripts onto the initrd, and the
kernel executes the scripts as an extended kernel command line.
Need to add tests to test that the happened. To test the bootconfig
properly, the initrd needs to be updated and the kernel rebooted. ktest is
the perfect solution to perform these tests.
Add a example bootconfig.conf in the tools/testing/ktest/examples/include
and example bootconfig scripts in tools/testing/ktest/examples/bootconfig
and also include verifier scripts that ktest will install on the target
and run to make sure that the bootconfig options in the scripts took place
after the target rebooted with the new initrd update.

Perl, as with most scripting languages, is fairly flexible in how /
where you can define things, and it will (for the most part) do what you
would expect it to do. This however can lead to situations, like with
ktest, where things get muddled over time.
This pushes the variable definitions back up to the top, followed by
functions, with the main script executables down at the bottom, INSTEAD
of being somewhat mish-mashed together in certain places. This mostly
has the advantage of making it more obvious where things are initially
defined, what functions are there, and ACTUALLY where the main script
starts executing, and should make this a little more approachable.

Emacs and Vi(m) have different styles of dealing with perl syntax
which can lead to slightly inconsistent indentation, and makes the
code slightly harder to read. Emacs assumes a more perl recommended
standard of 4 spaces (1 column) or tab (two column) indentation.
Vi(m) tends to favor just normal spaces or tabs depending on what
was being used.
This gives the basic hinting to Emacs and Vim to do what is
expected to be basically consistent.
Emacs:
- Explicitly flip into perl mode, cperl would require
more adjustments
Vi(m):
- Set softtabs=4 which will flip it over to doing
indentation the way you would expect from Emacs

If it fails to send email, then try again without the log file stating that
it failed to send an email. Obviously this will not be of use if the sending
of email failed for some other reasons, but it will at least give the user

This issue was first noticed when I was testing different kernels on
Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a
kernel entry was added successfully and the index of that kernel entry was
retrieved correctly, ktest still wouldn't reboot the system into
user-specified kernel.
The bug was spotted in subroutine reboot_to where the if-statement never
checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be
set for the next boot.
Add a check for "grub2bls" so that $grub_reboot $grub_number can
be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to
the correct kernel.

If the log file for a given test is larger than the max size given then use
set the seek from the end of the log file instead of from the start of the
test.

Add the ktest config option MAIL_MAX_SIZE that will limit the size of the
log file that is placed into the email on failure.

The log file should be up to date to whatever is happening in ktest.
Disable buffering to the LOG output file handle.

Currently, every write to the log file is done by opening the file, writing
to it, then closing the file. This rather expensive. Just open it at the
beginning and close it at the end.

There is a NOT DEFINED operator, but there is not an operator that can
negate any other expression.
For example: NOT (${FOO} == boot || ${BAR} == run)
Add the keyword NOT to allow the ktest.pl config files to negate operators.

Currently, if a PRE_TEST is defined and ran, but fails, there's nothing
currently available to make the test fail too. Add a PRE_TEST_DIE option that
when set, if a PRE_TEST is defined and fails, the test will die too.

If a log file is defined and the test were to error, a print statement is
made that shows the user where the log file is to examine it further. But
this is not done if the test were to succeed.
I find it annoying that it does not show where the log file is on success,
as I run several different tests that place their log files in various
locations, and even though the test pass, there's things I want to look at
in the log file (like warnings). It is much easier to find where the log
file is, if it is displayed at the end of a test.

When performing a automatic config bisect via ktest.pl, it is very useful to
have a copy of each of the bisects used. This way, if a bisect were to go
wrong, it is possible to retrace the steps and continue at the location
before the error was made.
The ktest.pl will make a copy of the good and bad configs, labeled as such,
as well as a number attached to it that represents the iteration of the
bisect. These files are saved in the ktest temp directory where it currently
stores the good and bad config files.

Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.
Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.

For the last time, I screwed up my ktest config file, and the build went
into the default "randconfig", blowing away the .config that I had set up.
The reason for the default randconfig was because when this was first
written, I wanted to do a bunch of randconfigs. But as time progressed,
ktest isn't about randconfig anymore, and because randconfig destroys the
config in the build directory, it's a dangerous default to have. Use
oldconfig as the default.
