selftests: add EXTRA_CLEAN for clean targetSome testcases need the clean extra data after running. This patchintroduce the "EXTRA_CLEAN" variable to address this requirement.After KBUILD_OUTPUT is enabled in later patch, it will be easy todecide to if we need do the cleanup in the KBUILD_OUTPUT path(if thetestcase ran immediately after compiled).Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/kcmp/Makefile

88baa78d - selftests: remove duplicated all and clean target

Tue, 29 Nov 2016 11:55:47 +0000

selftests: remove duplicated all and clean targetCurrently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES toindicate the test program, extended test program and test files. It iseasy to understand the purpose of these files. But mix of compiled anduncompiled files lead to duplicated "all" and "clean" targets.In order to remove the duplicated targets, introduce TEST_GEN_PROGS,TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiledobjects.Also, the later patch will make use of TEST_GEN_XXX to redirect thesefiles to output directory indicated by KBUILD_OUTPUT or O.And add this changes to "Contributing new tests(details)" ofDocumentation/kselftest.txt.Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/kcmp/Makefile

5e29a910 - selftests: Introduce minimal shared logic for running tests

Wed, 11 Mar 2015 04:05:59 +0000

selftests: Introduce minimal shared logic for running testsThis adds a Make include file which most selftests can then include toget the run_tests logic.On its own this has the advantage of some reduction in repetition, andalso means the pass/fail message is defined in fewer places.However the key advantage is it will allow us to implement install verysimply in a subsequent patch.The default implementation just executes each program in $(TEST_PROGS).We use a variable to hold the default implementation of $(RUN_TESTS)because that gives us a clean way to override it if necessary, ie. usingoverride. The mount, memory-hotplug and mqueue tests use that to providea different implementation.Tests are not run via /bin/bash, so if they are scripts they must beexecutable, we add a+x to several.Signed-off-by: Michael Ellerman Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/kcmp/Makefile

d97b46a6 - syscalls, x86: add __NR_kcmp syscall

Thu, 31 May 2012 23:26:44 +0000

syscalls, x86: add __NR_kcmp syscallWhile doing the checkpoint-restore in the user space one need to determinewhether various kernel objects (like mm_struct-s of file_struct-s) areshared between tasks and restore this state.The 2nd step can be solved by using appropriate CLONE_ flags and theunshare 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 toprovide some mm_struct ID of a task to its proc file, but showing suchinfo 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 (whichcharacteristics should be compared), the comparison type and (in case ofcomparison 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.[akpm@linux-foundation.org: fix up selftests, warnings][akpm@linux-foundation.org: include errno.h][akpm@linux-foundation.org: tweak comment text]Signed-off-by: Cyrill Gorcunov Acked-by: "Eric W.
