2012-05-31syscalls, x86: add __NR_kcmp syscallCyrill Gorcunov3-1/+124
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.

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).

2012-05-22ktest: Add USE_OUTPUT_MIN_CONFIG to avoid prompt on make_min_configSteven Rostedt2-1/+16
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 Rostedt2-0/+24
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 Rostedt1-0/+11
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 Rostedt1-2/+8
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 Dill1-1/+1
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 Rostedt1-2/+10
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.

Currently the option used to scp both the modules to the target as well as the kernel image are the same (SCP_TO_TARGET). But some embedded boards may require them to be different. The modules may need to be put directly on the board, but the kernel image may need to go to a tftpserver. Add the option SCP_TO_TARGET_INSTALL that will allow the user to change the config so that they may have the modules and image got to different machines.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest While demoing ktest at ELC in 2012, it was embarrassing that the make_min_config test failed to work because the snowball board I was testing it against had a config that would not build.

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>

2011-12-22ktest: Detect typos in option namesSteven Rostedt2-80/+139
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.

Currently the patchcheck, bisect, and config_bisect variables are only able to be set per test. You can not set a default value for them. By letting default values be set, it makes some config files a bit easier, and also makes it easier to find typos in the option names. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

The option SWITCH_TO_GOOD is added, where if it is defined, the command that is specified as its value will be executed before doing a reboot into a known good image. The option SWITCH_TO_TEST is added, where if it is defined, the command that is specified as its value will be executed before doing a reboot into the test image.

2011-12-22ktest: Allow overriding bisect test resultsSteven Rostedt2-0/+83
When running the ktest git bisect test, if the BISECT_TYPE is "test", the bisect is determined to be good or bad based off of the error code of the test that is run. Currently, if the test returns 0, it is considered a pass (good), a non-zero is considered a fail (bad). But it has been requested to add more options, and also change the meanings of the error codes of the test. For example, one may want the test to detect if the commit is not good or bad, (maybe the bisect came to a point where the code in question does not exist). The test could report an error code that should tell ktest to skip the commit. Also, a test could detect that something is horribly wrong and the biscet should just be aborted. The new options: BISECT_RET_GOOD BISECT_RET_BAD BISECT_RET_SKIP BISECT_RET_ABORT BISECT_RET_DEFAULT have been added. The first 4 take an integer value that will represent if the test should be considered a pass, fail, neither good nor bad, or abort respectively. The BISECT_RET_DEFAULT will bo whatever is not defined by the above codes. If only BISECT_RET_DEFAULT is defined, then all tests will do the default.

2011-12-22ktest: Only ask options needed for installSteven Rostedt1-5/+14
If all the tests are only for build or install, do not ask for options not needed to do the install, if the options do not exist. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-12-22ktest: When creating a new config, ask for BUILD_OPTIONSSteven Rostedt1-1/+14
When creating a new config, ask for the BUILD_OPTIONS variable that lets users add things like -j20 to the make. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-12-22ktest: Do not ask for some options if the only test is buildSteven Rostedt1-12/+31
When creating a ktest config or if te config only has build only tests, some of the manditory config options are not needed. Do not ask for them if all tests in the config file are just build tests.

2011-12-22ktest: Ask for type of test when creating a new configSteven Rostedt1-4/+12
When no argument is supplied to ktest, or the config applied does not exist and a new config is being created, instead of just using the default test type, give the user an option to pick the test type of either 'build, install, or boot'. Other options may be added later but then those would require more questions as they require more fields. But that's for another release of ktest to add that feature.

2011-12-22ktest: Allow bisect test to restart where it left offSteven Rostedt1-6/+64
If a bisect is killed for some reason, have ktest detect that a bisect is in progress and if so, allow the user to start the bisect where it left off. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-11-23ktest: When creating new config, allow the use of ${THIS_DIR}Steven Rostedt1-2/+17
Typing in a full path when you know that the path exists within the directory your are running is tedious and unnecessary. Allow the user to use ${PWD} if they want a dynamic path name which will be the path that ktest.pl is executed from or use ${THIS_DIR} which is a variable assigned `pwd` and the the variable will exist within the config, allowing the user to change it and affect all other paths using this variable as well Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-11-21ktest: Add default for ssh-user, build-target and target-imageSteven Rostedt1-1/+7
When a user runs ktest without an argument, or the argument given is not a config file that exists, ktest will ask the user a few questions to create a simple ktest config file. A few of the questions should have a default value set, that if anything it will make it easier for the user to know what is suppose to be in that value. These new values are: SSH_USER, BUILD_TARGET and TARGET_IMAGE Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-11-18ktest: Allow success logs to be storedRabin Vincent2-34/+52
