Linus Torvalds 8557b8e43a Greg Kroah-Hartman reported to me that the ktest of v4.10 locked up in an
infinite loop while doing the make mrproper. Looking into the cause I noticed
 that a recent update to the function run_command (used for running all
 shell commands, including "make mrproper") changed the internal loop to
 use the function wait_for_input. The wait_for_input uses select to look
 at two file descriptors. One is the file descriptor of the command it is
 running, the other is STDIN. The STDIN check was not checking the return
 status of the sysread call, and was also just writing a lot of data into
 syswrite without regard to the size of the data read.
 
 Changing the code to check the return status of sysread, and also to still
 process the passed in descriptor data without looping back to the select
 fixed Greg's problem.
 
 While looking at this code I also realized that the loop did not honor
 the timeout if STDIN always had input (or for some reason return error).
 this could prevent wait_for_input to timeout on the file descriptor it
 is suppose to be waiting for. That is fixed too.

Steven Rostedt (VMware) f7c6401ff8 ktest: Make sure wait_for_input does honor the timeout
The function wait_for_input takes in a timeout, and even has a default
timeout. But if for some reason the STDIN descriptor keeps sending in data,
the function will never time out. The timout is to wait for the data from
the passed in file descriptor, not for STDIN. Adding a test in the case
where there's no data from the passed in file descriptor that checks to see
if the timeout passed, will ensure that it will timeout properly even if
there's input in STDIN.

Steven Rostedt (VMware) 99c014a879 ktest: Fix while loop in wait_for_input
The run_command function was changed to use the wait_for_input function to
allow having a timeout if the command to run takes too much time. There was
a bug in the wait_for_input where it could end up going into an infinite
loop. There's two issues here. One is that the return value of the sysread
wasn't used for the write (to write a proper size), and that it should
continue processing the passed in file descriptor too even if there was
input. There was no check for error, if for some reason STDIN returned an
error, the function would go into an infinite loop and never exit.

Josh Poimboeuf 988427829b ktest: Restore tty settings after closing console
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.

Steven Rostedt (Red Hat) 22c37a9ac4 ktest: Allow tests to undefine default options
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.

Steven Rostedt (Red Hat) 6071c22e17 ktest: Rewrite the config-bisect to actually work
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.

Steven Rostedt (Red Hat) 961d9cacee ktest: Add BISECT_TRIES to bisect test
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.

Steven Rostedt (Red Hat) c75d22d9c6 ktest: Add eval '=~' command to modify variables in config file
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.

Steven Rostedt (Red Hat) 8e80bf05ff ktest: Add special variable ${KERNEL_VERSION}
Add a special variable that can be used in other variables called
${KERNEL_VERSION}. This will embed the current kernel version into
the variable. For example:

WARNINGS_FILE = ${OUTPUT_DIR}/warnings-${KERNEL_VERSION}

If the current version is v3.8 then the WARNINGS_FILE will become

  ${OUTPUT_DIR}/warnings-v3.8

With the new CLOSE_CONSOE_SIGNAL option, it too needs to be

Satoru Takeuchi 5a5d8e4844 ktest: Make the signal to terminate the console configurable
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.

Steven Rostedt (Red Hat) df5f7c6601 ktest: Reset grub menu cache with different machines
Different tests may use a different machine. In such cases, we need to
try to get the current grub menu index. If the same grub menu is used
for two different machines, it may not be at the same index on the
second machine. A search for the index must be performed again.

Steven Rostedt (Red Hat) 752d96657c ktest: Allow tests to use different GRUB_MENUs
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
ignore it.

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.

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.
