2012-07-31fault-injection: fix failcmd.sh warningAkinobu Mita
"fault-injection: add tool to run command with failslab or fail_page_alloc" added tools/testing/fault-injection/failcmd.sh to make it easier to inject slab/page allocation failures by fault injection. failcmd.sh prints the following warning when running with arguments for command. # ./failcmd.sh echo aaa failcmd.sh: line 209: [: echo: binary operator expected aaa This warning is caused by an improper check whether at least one parameter is left after parsing command options. Fix it by testing the length of $1 instead of $@ Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-07-30fault-injection: add tool to run command with failslab or fail_page_allocAkinobu Mita
This adds tools/testing/fault-injection/failcmd.sh to run a command while injecting slab/page allocation failures via fault injection. Example: Run a command "make -C tools/testing/selftests/ run_tests" with injecting slab allocation failure. # ./tools/testing/fault-injection/failcmd.sh \ -- make -C tools/testing/selftests/ run_tests Same as above except to specify 100 times failures at most instead of one time at most by default. # ./tools/testing/fault-injection/failcmd.sh --times=100 \ -- make -C tools/testing/selftests/ run_tests Same as above except to inject page allocation failure instead of slab allocation failure. # env FAILCMD_TYPE=fail_page_alloc \ ./tools/testing/fault-injection/failcmd.sh --times=100 \ -- make -C tools/testing/selftests/ run_tests Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-07-30ktest: Allow perl regex expressions in conditional statementsSteven Rostedt

2012-07-30ktest: Ignore errors it tests if IGNORE_ERRORS is setSteven Rostedt
The option IGNORE_ERRORS is used to allow a test to succeed even if a warning appears from the kernel. Sometimes kernels will produce warnings that are not associated with a test, and the user wants to test something else. The IGNORE_ERRORS works for boot up, but was not preventing test runs to succeed if the kernel produced a warning. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-07-20ktest: Reset saved min (force) configs for each testSteven Rostedt
The min configs are saved in a perl hash called force_configs, and this hash is used to add configs to the .config file. But it was not being reset between tests and a min config from a previous test would affect the min config of the next test causing undesirable results. Reset the force_config hash at the start of each test. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-07-19ktest: Add check for bug or panic during rebootSteven Rostedt
Usually the target is booted into a dependable kernel when a test starts. The test will install the test kernel and reboot the box. But there may be a time that the kernel is running an unreliable kernel and the reboot may crash. Have ktest detect crashes on a reboot and force a power-cycle instead. This can usually happen if a test kernel was installed to run manual tests, but the user forgot to reboot to the known good kernel. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-07-19ktest: Add MAX_MONITOR_WAIT optionSteven Rostedt
If the console is constantly outputting content, this can cause ktest to get stuck waiting on the monitor to settle down. The option MAX_MONITOR_WAIT is the maximum time (in seconds) for ktest to wait for the console to flush. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-07-19ktest: Fix config bisect with how make oldnoconfig worksSteven Rostedt
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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-07-19ktest: Add CONFIG_BISECT_CHECK optionSteven Rostedt
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 minconfig (defined by a user) to apply before booting, it is possible that the minconfig could actually make the bad config work (minconfigs 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. And yes, I did get burned by this.

2012-07-19ktest: Add PRE/POST_KTEST and TEST optionsSteven Rostedt
In order to let the user add commands before and after ktest runs, the PRE_KTEST and POST_KTEST options are defined. They hold shell commands that will execute befor ktest runs its first test, as well as when it completed its last test. The PRE_TEST and POST_TEST will be run befor and after (respectively) for a given test. They can either be global (done for all tests) or defined by a single test.

2012-05-31syscalls, x86: add __NR_kcmp syscallCyrill Gorcunov
While doing the checkpoint-restore in the user space one need to determine whether various kernel objects (like mm_struct-s of file_struct-s) are shared between tasks and restore this state. The 2nd step can be solved by using appropriate CLONE_ flags and the unshare syscall, while there's currently no ways for solving the 1st one. One of the ways for checking whether two tasks share e.g. mm_struct is to provide some mm_struct ID of a task to its proc file, but showing such info considered to be not that good for security reasons. Thus after some debates we end up in conclusion that using that named 'comparison' syscall might be the best candidate. So here is it -- __NR_kcmp. It takes up to 5 arguments - the pids of the two tasks (which characteristics should be compared), the comparison type and (in case of comparison of files) two file descriptors. Lookups for pids are done in the caller's PID namespace only. At moment only x86 is supported and tested.

2012-05-22ktest: Add useful example configsSteven Rostedt
I've been asked several times to provide more useful example configs for ktest.pl, as the sample.conf is too complex (because it explains all configs). This adds configs broken up by use case, and these configs are based on actual configs that I use on a daily basis. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-05-22ktest: Add USE_OUTPUT_MIN_CONFIG to avoid prompt on make_min_configSteven Rostedt
If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the user and ask them if the OUTPUT_MIN_CONFIG should be used as the starting point for make_min_config instead of MIN_CONFIG. This is usually the case, and to allow the user to do so, which is helpful if the user is creating different min configs based on tests, and they know one is a superset of another test, they can set USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting to use the OUTPUT_MIN_CONFIG and it will just use it. If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to use MIN_CONFIG instead. The default is that USE_OUTPUT_MIN_CONFIG is undefined. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-05-21ktest: Add MIN_CONFIG_TYPE to allow making a minum .config that has networkSteven Rostedt
Add a MIN_CONFIG_TYPE that can be set to 'test' or 'boot'. The default is 'boot' which is what make_min_config has done previously: makes a config file that is the minimum needed to boot the target. But when MIN_CONFIG_TYPE is set to 'test', not only must the target boot, but it must also successfully run the TEST. This allows the creation of a config file that is the minimum to boot and also perform ssh to the target, or anything else a developer wants. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-05-18ktest: Fix kernelrevision with POST_BUILDSteven Rostedt
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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-05-01ktest: Fix reboot on success stopping all rebootsSteven Rostedt
The change to let individual tests decide to reboot the machine on success of the entire test also prevented errors from rebooting when an error was detected. The "no_reboot" variable was only cleared if the test had reboot_on_success set. But the no_reboot variable also prevents the test rebooting when an error was detected even when REBOOT_ON_ERROR was set. Add a new "reboot_success" variable that is used to determine if the test should reboot on success and not touch the no_reboot variable. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-05-01ktest.pl: Fix combined usage of BISECT_REVERSE and BISECT_SKIPRuss Dill
When BISECT_REVERSE and BISECT_SKIP are used together with boot or test testing, build failures are treated as boot or test failures and 'git bisect bad' is executed instead of 'git bisect skip'. This is because the $ret value of -1 is treated as a build failure, but the $reverse_bisect logic does not properly handle this. Simple fix, only invert it if it is positive.

2012-03-21ktest: Allow a test to override REBOOT_ON_SUCCESSSteven Rostedt
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.

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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

Bring a first selftest in the relevant directory. This tests several combinations of breakpoints and watchpoints in x86, as well as icebp traps and int3 traps. Given the amount of breakpoint regressions we raised after we merged the generic breakpoint infrastructure, such selftest became necessary and can still serve today as a basis for new patches that touch the do_debug() path.

2012-01-12selftests: new very basic kernel selftests directoryFrederic Weisbecker
Bring a new kernel selftests directory in tools/testing/selftests. To add a new selftest, create a subdirectory with the sources and a makefile that creates a target named "run_test" then add the subdirectory name to the TARGET var in tools/testing/selftests/Makefile and tools/testing/selftests/run_tests script. This can help centralizing and maintaining any useful selftest that developers usually tend to let rust in peace on some random server.

2012-01-04ktest: Add INGORE_ERRORS to ignore warnings in boot upSteven Rostedt
When testing a kernel that has warnings, ktest.pl will fail the test when it sees the warning. If you need to test the the kernel and want to ignore the errors that are produced, the option IGNORE_ERRORS has been added. When IGNORE_ERRORS is set to something other than 0, it will ignore call traces due to WARN_ON(). Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-01-04ktest: Still do reboot even for REBOOT_TYPE = scriptSteven Rostedt
The REBOOT_TYPE may be either grub or script, if it is script it is expected that a REBOOT_SCRIPT is defined. With the SWITCH_TO_TEST which is the complement of SWITCH_TO_GOOD, which does basically the same thing as REBOOT_SCRIPT and but for both grub and script, the REBOOT_SCRIPT does not need to be mandatory anymore. Do not require the REBOOT_SCRIPT and always run the reboot code for both grub and script. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2011-12-22ktest: Fix compare script to test if options are not documentedSteven Rostedt
The compare script compare-ktest-sample.pl checks for options that are defined in ktest.pl and not documented in samples.conf, as well as samples in samples.conf that are not used in ktest.pl. With the switch to the hash format to initialize the ktest variables the compare script needs to be updated to handle the change. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-12-22ktest: Detect typos in option namesSteven Rostedt
It becomes quite annoying when you go to run a test and then realize that you typed an option name wrong, and the test starts doing the default action and not what you expected it to do. It is even more annoying when you wake up the next day after running the test over night when you discover this. By testing if all options specified in a config file are used by either ktest or were used in one of the option's values we can see if there are any dangling options that were not used. In such a case, show the user the options that were not used and ask them if they want to continue or not. The option IGNORE_UNUSED was also added to allow the user to override this feature.
