tools/testing/selftests/sigaltstack/sas.c: improve output of sigaltstack testcase

2017-02-28T02:43:45Z

Currently it uses %i for bitmasks, which makes it difficult to properly decode the values. Use %x instead.

selftests: remove duplicated all and clean target

2017-01-05T20:41:35Z

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. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

signals/sigaltstack: Change SS_AUTODISARM to (1U << 31)

2016-05-04T06:34:14Z

Using bit 4 divides the space of available bits strangely. Use bit 31 instead so that we have a better chance of keeping flag and mode bits separate in the long run.

signals/sigaltstack: Report current flag bits in sigaltstack()

2016-05-04T06:34:14Z

sigaltstack()'s reported previous state uses a somewhat odd convention, but the concept of flag bits is new, and we can do the flag bits sensibly. Specifically, let's just report them directly. This will allow saving and restoring the sigaltstack state using sigaltstack() to work correctly.

selftests/sigaltstack: Fix the sigaltstack test on old kernels

selftests/sigaltstack: Add new testcase for sigaltstack(SS_ONSTACK|SS_AUTODISARM)

2016-05-03T06:37:59Z

This patch adds the test case for SS_AUTODISARM flag. The test-case tries to set SS_AUTODISARM flag and checks if the nested signal corrupts the stack after swapcontext().
