git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest Pull ktest fixes from Steven Rostedt: "Greg Kroah-Hartman reported to me that the ktest of v4.11-rc1 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 function 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" * tag 'ktest-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest: ktest: Make sure wait_for_input does honor the timeout ktest: Fix while loop in wait_for_input
2017-03-08ktest: Make sure wait_for_input does honor the timeoutSteven Rostedt (VMware)
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.

2017-03-08ktest: Fix while loop in wait_for_inputSteven Rostedt (VMware)
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.

When performing a reboot of the test box, try to ssh to it. If it can't connect for 5 seconds, then powercycle the box.

2015-01-29ktest: Show times for build, install, boot and testSteven Rostedt (Red Hat)
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).

2015-01-27ktest: Restore tty settings after closing consoleJosh Poimboeuf
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.

2014-11-21ktest: Allow tests to undefine default optionsSteven Rostedt (Red Hat)
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.

2014-11-21ktest: Fix make_min_config to handle new assign_configs callSteven Rostedt (Red Hat)
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.

2014-10-07ktest: Fix check for new kernel success on rebooting to good kernelSteven Rostedt (Red Hat)
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.

2014-04-23ktest: Put back in the CONFIG_BISECT_CHECKSteven Rostedt (Red Hat)
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.

2014-04-23ktest: Rewrite the config-bisect to actually workSteven Rostedt (Red Hat)
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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2014-01-18ktest: Add BISECT_TRIES to bisect testSteven Rostedt (Red Hat)
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. Suggested-by: "Paul E.

2013-02-05ktest: Ignore warnings during rebootSteven Rostedt (Red Hat)
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.

2013-02-05ktest: Search for linux banner for successful rebootSteven Rostedt (Red Hat)
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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2013-01-31ktest: Add make_warnings_file and process full warningsSteven Rostedt (Red Hat)
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.
