      x86, selftests: Add sigreturn selftest · 3f705dfd
      由 Andy Lutomirski 提交于 
      This is my sigreturn test, added mostly unchanged from its old
home. It exercises the sigreturn(2) syscall, specifically
focusing on its interactions with various IRET corner cases.

It tests for correct behavior in several areas that were
historically dangerously buggy. For example, it exercises espfix
on kernels of both bitnesses under various conditions, and it
contains testcases for several now-fixed bugs in IRET error
handling.

If you run it on older kernels without the fixes, your system will
crash. It probably won't eat your data in the process.

There is no released kernel on which the sigreturn_64 test will
pass, but it passes on tip:x86/asm.

I plan to switch to lib.mk for Linux 4.2.

I'm not using the ksft_ helpers at all yet.  I can do that later.

      selftests: Add tool to generate kselftest tar archive · f901caaf
      由 Shuah Khan 提交于 
      gen_kselftest_tar.sh tool generates kselftest tar archive. This tool
supports uncompressed tar, gz, bz, and xz compression formats and the
default compression format is gzip. This tool runs kselftest install
tool as its back-end.

Usage:
cd tools/testing/selftests
./gen_kselftest_tar [ tar | targz | tarbz2 | tarxz ]

      selftests: Add kselftest install tool · 21979405
      由 Shuah Khan 提交于 
      kselftest_install.sh tool installs selftests in default location
which is tools/testing/selftests/kselftest or an user specified
location. This tool invokes back-end selftests install target with
the install location.

Usage:
cd tools/testing/selftests
./kselftest_install.sh [ install_dir ]

      selftests: Fix build failures when invoked from kselftest target · 67d8712d
      由 Shuah Khan 提交于 
      Several tests that rely on implicit build rules fail to build,
when invoked from the main Makefile kselftest target. These
failures are due to --no-builtin-rules and --no-builtin-variables
options set in the inherited MAKEFLAGS.

--no-builtin-rules eliminates the use of built-in implicit rules
and --no-builtin-variables is for not defining built-in variables.
These two options override the use of implicit rules resulting in
build failures. In addition, inherited LDFLAGS result in build
failures and there is no need to define LDFLAGS.  Clear LDFLAGS
and MAKEFLAG when make is invoked from the main Makefile kselftest
target. Fixing this at selftests Makefile avoids changing the main
Makefile and keeps this change self contained at selftests level.

      selftests: Add install target · 32dcfba6
      由 Michael Ellerman 提交于 
      This adds make install support to selftests. The basic usage is:

$ cd tools/testing/selftests
$ make install

That installs into tools/testing/selftests/install, which can then be
copied where ever necessary.

The install destination is also configurable using eg:

$ INSTALL_PATH=/mnt/selftests make install

The implementation uses two targets in the child makefiles. The first
"install" is expected to install all files into $(INSTALL_PATH).

The second, "emit_tests", is expected to emit the test instructions (ie.
bash script) on stdout. Separating this from install means the child
makefiles need no knowledge of the location of the test script.

      selftests: Introduce minimal shared logic for running tests · 5e29a910
      由 Michael Ellerman 提交于 
      This adds a Make include file which most selftests can then include to
get the run_tests logic.

On its own this has the advantage of some reduction in repetition, and
also means the pass/fail message is defined in fewer places.

However the key advantage is it will allow us to implement install very
simply 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. using
override. The mount, memory-hotplug and mqueue tests use that to provide
a different implementation.

Tests are not run via /bin/bash, so if they are scripts they must be
executable, we add a+x to several.
