selftests/vm: add a test for virtual address range mapping

2017-05-09T00:15:16+00:00

This verifies virtual address mapping below and above the 128TB range
and makes sure that address returned are within the expected range
depending upon the hint passed from the user space.

userfaultfd: selftest: combine all cases into a single executable

2017-05-03T22:52:10+00:00

Currently, selftest for userfaultfd is compiled three times: for
anonymous, shared and hugetlb memory.  Let's combine all the cases into
a single executable which will have a command line option for selection
of the test type.

userfaultfd: selftest: vm: allow to build in vm/ directory

2017-03-10T01:01:10+00:00

linux/tools/testing/selftests/vm $ make

  gcc -Wall -I ../../../../usr/include     compaction_test.c -lrt -o /compaction_test
  /usr/lib/gcc/x86_64-pc-linux-gnu/4.9.4/../../../../x86_64-pc-linux-gnu/bin/ld: cannot open output file /compaction_test: Permission denied
  collect2: error: ld returned 1 exit status
  make: *** [../lib.mk:54: /compaction_test] Error 1

Since commit a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT")
selftests/vm build fails if run from the "selftests/vm" directory, but
it works in the selftests/ directory.  It's quicker to be able to do a
local vm-only build after a tree wipe and this patch allows for it
again.

userfaultfd: shmem: add userfaultfd_shmem test

2017-02-23T00:41:29+00:00

The test verifies that anonymous shared mapping can be used with userfault
using the existing testing method.  The shared memory area is allocated
using mmap(..., MAP_SHARED | MAP_ANONYMOUS, ...) and released using
madvise(MADV_REMOVE)

userfaultfd: hugetlbfs: add userfaultfd_hugetlb test

2017-02-23T00:41:28+00:00

Test userfaultfd hugetlb functionality by using the existing testing
method (in userfaultfd.c).  Instead of an anonymous memeory, a hugetlbfs
file is mmap'ed private.  In this way fallocate hole punch can be used
to release pages.  This is because madvise(MADV_DONTNEED) is not
supported for huge pages.

Use the same file, but create wrappers for allocating ranges and
releasing pages.  Compile userfaultfd.c with HUGETLB_TEST defined to
produce an executable to test userfaultfd hugetlb functionality.

selftests: enable O and KBUILD_OUTPUT

2017-01-05T20:42:22+00:00

Enable O and KBUILD_OUTPUT for kselftest. User could compile kselftest
to another directory by passing O or KBUILD_OUTPUT. And O is high
priority than KBUILD_OUTPUT.

selftests: add default rules for c source file

2017-01-05T20:42:01+00:00

There are difference rules for compiling c source file in different
testcases. In order to enable KBUILD_OUTPUT support in later patch,
this patch introduce the default rules in
"tools/testing/selftest/lib.mk" and remove the existing rules in each
testcase.

selftests: remove duplicated all and clean target

2017-01-05T20:41:35+00:00

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.

selftests: expanding more mlock selftest

2016-10-08T01:46:28+00:00

This patch will randomly perform mlock/mlock2 on a given memory region,
and verify the RLIMIT_MEMLOCK limitation works properly.
