Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled 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 compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt.

One problem with seccomp was that ptrace could be used to change a syscall after seccomp filtering had completed. This was a well documented limitation, and it was recommended to block ptrace when defining a filter to avoid this problem. This can be quite a limitation for containers or other places where ptrace is desired even under seccomp filters. This adds tests for both SECCOMP_RET_TRACE and PTRACE_SYSCALL manipulations.

By adding TRACEHOOK support we now get a clean user interface to access registers via PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS. The user-visible regset struct user_regs_struct and user_fp_struct are modelled similiar to x86 and can be accessed via PTRACE_GETREGSET. Signed-off-by: NHelge Deller <deller@gmx.de>

This adds self-test support on MIPS, based on RFC patch from Kees Cook. Modifications from the RFC: - support the O32 syscall which passes the real syscall number in a0. - Use PTRACE_{GET,SET}REGS - Because SYSCALL_NUM and SYSCALL_RET are the same register, it is not possible to test modifying the syscall return value when skipping, since both would need to set the same register. Therefore modify that test case to just detect the skipped test. Tested on MIPS32r2 / MIPS64r2 with O32, N32 and N64 userlands.

Create the config file in each directory of testcase which need more kernel configuration than the default defconfig. User could use these configs with merge_config.sh script: Enable config for specific testcase: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/xxx/config Enable configs for all testcases: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/*/config Signed-off-by: NBamvor Jian Zhang <bamvor.zhangjian@linaro.org> Reviewed-by: NShuah Khan <shuahkh@osg.samsung.com> Signed-off-by: NShuah Khan <shuahkh@osg.samsung.com>

Some architectures do not implement PTRACE_GETREGSET nor PTRACE_SETREGSET (required by HAVE_ARCH_TRACEHOOK) but only implement PTRACE_GETREGS and PTRACE_SETREGS (e.g. User-mode Linux). This improve seccomp selftest portability for architectures without HAVE_ARCH_TRACEHOOK support by defining a new trigger HAVE_GETREGS. For now, this is only enabled for i386 and x86_64 architectures. This is required to be able to run this tests on User-mode Linux.

Certain syscall emulation layers strictly check that the number of arguments match what the syscall handler expects. The KILL_one_arg_one and KILL_one_arg_six tests passed more parameters than expected to various syscalls, causing failures in this emulation mode. Instead, test using syscalls that take the appropriate number of arguments.

Changing arm64 syscalls is done via a specific register set, more like s390 than like arm (specific ptrace call) and x86 (part of general registers). Since (restarting) poll doesn't exist on arm64, switch to using nanosleep for testing restart_syscall. And since it looks like the syscall ABI is inconsistent on arm-compat, so we must work around it (and document it) in the test.

This adds support for s390 to the seccomp selftests. Some improvements were made to enhance the accuracy of failure reporting, and additional tests were added to validate assumptions about the currently traced syscall. Also adds early asserts for running on older kernels to avoid noise when the seccomp syscall is not implemented.

The seccomp_bpf test uses BPF_LD|BPF_W|BPF_ABS to load 32-bit values from seccomp_data->args. On big endian machines this will load the high word of the argument, which is not what the test wants. Borrow a hack from samples/seccomp/bpf-helper.h which changes the offset on big endian to account for this.

This imports the existing seccomp test suite into the kernel's selftests tree. It contains extensive testing of seccomp features and corner cases.
