Seems that some of the new console logic causes doprint to possibly
get evaluated. When printing a commit message that contains parenthesis,
it fails with a shell parsing error.
This gets fixed when we add quotes around the $item variable, and prevent
it from being evaluated by any shell commands.

Since both success and failure may shortcut and exit ktest, it is better
to print the status times there too. Once times are printed, the values
for the times are reset, so they will not print more than once.

Seeing the times for how long a build, install, reboot and the
test takes is helpful for analyzing the test process. Seeing
how different changes affect the timings.
Show the build, install, boot and test times when at the end of
the test, or between each interval for tests that do those
mulitple times (like bisect and patchcheck).

When ktest runs the console program as a child process, the parent and
child share the same tty for stdin and stderr. This is problematic when
using a libvirt target. The "virsh console" program makes a lot of
changes to the tty settings, making ktest's output hard to read
(carriage returns don't work). After ktest exits, the terminal is
unusable (CRs broken, stdin isn't echoed).
I think the best way to fix this issue would be to create a
pseudoterminal (pty pair) so the child process would have a dedicated
tty, and then use pipes to connect the two ttys. I'm not sure if that's
overkill, but it's far beyond my current Perl abilities.
This patch is a much easier way to (partially) fix this issue. It saves
the tty settings before opening the console and restores them after
closing it. There are still a few places where ktest prints mangled
output while the console is open, but the output is much more legible
overall, and the terminal works just fine after ktest exits.

Tests can set options that override the default ones. But if a test
tries to undefine a default option, it is simply ignored and the
default option stays as is.
For example, if you want to have a test that defines no MIN_CONFIG
then the test should be able to do that with:
TEST_START
MIN_CONFIG =
Which should make MIN_CONFIG not defined for that test. But the way
the code currently works, undefined options in tests are dropped.
This is because the NULL options are evaluated during the reading of
the config file and since one can disable default options in the default
section with this method, it is evaluated there (the option turns to a
undef). But undef options in the test section mean to use the default
option.
To fix this, keep the empty string in the option during the reading
of the config file, and then evaluate it when running the test. This
will allow tests to null out default options.

Commit 6071c22e1755 "ktest: Rewrite the config-bisect to actually work"
fixed the config-bisect to work nicely but in doing so it broke
make_min_config by changing the way assign_configs works.
The assign_configs function now adds the config to the hash even if
it is disabled, but changes the hash value to be that of the
line "# CONFIG_FOO is not set". Unfortunately, the make_min_config
test only checks to see if the config is removed. It now needs to
check if the config is in the hash and not set to be disabled.

If git bisect reply is being used in the bisect tests, don't bother
doing the git bisect good or git bisect bad calls. The git bisect
reply will override them anyway, and that's called immediately

The reboot function when rebooting back to a good kernel has a check
to make sure that a new kernel was indeed booted. But that check
uses a timeout value, which when calling the monitor will still
return success if the timeout is hit (no bug was found). It should
return an error to let the reboot code know that a new kernel was
not reached. Only the reboot code checks the return value of the
monitor.

The new rewrite left out the CONFIG_BISECT_CHECK, which allows the
user to test that their "bad" config still is bad and their "good"
config still is good. This is especially important as the configs
are passed through a "make oldconfig" to update them with the lastest
kernel. Things could change that causes a bad config to work, or a
good config to break. The check is done after the configs have run
through the oldconfig processing.

I never liked the way config-bisect worked. I would assume the bad config
had some config that broke the system. But it would not work if the bad
config just happened to be missing something that the good config had.
I rewrote the config-bisect to do this properly. It does a diff of the two
configs, and sets half of the configs that are in one and not the other.
The way it works is that when it "sets", it really just makes one copy
what the other has. That is, a "set" can be setting a:
# CONFIG_FOO is not set
Basically, it looks at the differences between the two files and makes
them similar until it comes down to one config that makes it work or
not work depending on if it is set or not.
Note, if more than one config change makes the bad config not work, it
will only find one of them. But this is true with all bisect logic.

Pull ktest updates from Steven Rostedt:
"Here's some basic updates to ktest.pl. They include:
- add config to modify the signal to terminate console
- update to documentation (missing some config options)
- add KERNEL_VERSION variable to use for other configs
- add '=~' to let configs eval other configs
- add BISECT_TRIES to run multiple tests per git bisect good"
* tag 'ktest-v3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest:
ktest: Add BISECT_TRIES to bisect test
ktest: Add eval '=~' command to modify variables in config file
ktest: Add special variable ${KERNEL_VERSION}
ktest: Add documentation of CLOSE_CONSOLE_SIGNAL
ktest: Make the signal to terminate the console configurable
|
|
For those cases that it takes several tries to hit a bug, it would be
useful for ktest.pl to try a test multiple times before it considers
the test as a pass. To accomplish this, BISECT_TRIES ktest config
option has been added. It is default to one, as most of the time a
bisect only needs to try a test once. But the user can now up this
to make ktest run a given test multiple times. The first failure
that is detected will set a bisect bad. It only repeats on success.
Note, as with all race bugs, there's no guarantee that if it succeeds,
it is really a good bisect. But it helps in case the bug is somewhat
reliable.
You can set BISECT_TRIES to zero, and all tests will be considered
good, unless you also set BISECT_MANUAL.

With the added variable ${KERNEL_VERSION}, it is useful to be
able to use parts of it for other variables.
For example, if you want to create a warnings file for each major
kernel version to test sub versions against you can create
your warnings file with like this:
WARNINGS_FILE = warnings-file-${KERNEL_VERSION}
But this may add 3.8.12 or something, and we want all 3.8.* to
use the same file, and 3.10.* to use another file, and so on.
With the eval command we can, by adding:
WARNINGS_FILE =~ s/(-file-\d+\.\d+).*/$1/
Which will chop off the extra characters after the 3.8.

Add a special variable that can be used in other variables called
${KERNEL_VERSION}. This will embed the current kernel version into

${OUTPUT_DIR}/warnings-v3.8

Currently ktest sends SIGINT to terminate the console.
However, there are consoles which do not exit by this signal, for example,
in my case, "virsh console <guest OS>". In such case, ktest is blocked in
close_console(). It prevents this automate test.
This patch adds new option CLOSE_CONSOLE_SIGNAL which mean the
signal to terminate the console. Since its default value is "INT",
the original behavior isn't changed.

To save connecting and searching for a given grub menu for each test,
ktest.pl will cache the grub number it found. The problem is that
different tests might use a different grub menu, but ktest.pl will

Instead, have ktest.pl check if the grub menu it used to cache the
content is the same as when it grabbed the menu. If not, grab it again,
otherwise just return the cached value.

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

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.

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.

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.

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

Commit fb16d891 "kconfig: replace 'oldnoconfig' with 'olddefconfig', and

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.

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.
