selftest/memfd: include default header install path

2015-04-02T18:41:03Z

Include the default path for INSTALL_HDR_PATH to make it less intrusive when cross building. Signed-off-by: Tyler Baker Signed-off-by: Shuah Khan

selftest/memfd: enable cross compilation

2015-04-02T18:40:34Z

Use the CC variable instead of hard coding gcc. Also clean up the compiler options by creating a CFLAGS variable. Signed-off-by: Tyler Baker Signed-off-by: Shuah Khan

selftests: Introduce minimal shared logic for running tests

2015-03-13T21:13:40Z

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.

selftests/memfd: Run test on all architectures

2014-09-17T14:00:16Z

Remove the dependence on x86 to run the memfd test. Verfied on 32-bit powerpc. Signed-off-by: Pranith Kumar Reviewed-by: David Herrmann Signed-off-by: Shuah Khan

tools: selftests: fix build issue with make kselftests target

2014-08-29T23:28:17Z

Fix the typo of ARCH when running 'make kselftests'. Change the 'X86' to 'x86'. Test by compilation. Signed-off-by: Phong Tran Cc: David Herrmann Cc: Hugh Dickins Cc: Shuah Khan Cc: Sam Ravnborg Cc: Michal Marek Cc: Shuah Khan Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

selftests: add memfd/sealing page-pinning tests

2014-08-08T22:57:31Z

Setting SEAL_WRITE is not possible if there're pending GUP users. This commit adds selftests for memfd+sealing that use FUSE to create pending page-references. FUSE is very helpful here in that it allows us to delay direct-IO operations for an arbitrary amount of time. This way, we can force the kernel to pin pages and then run our normal selftests.

selftests: add memfd_create() + sealing tests

2014-08-08T22:57:31Z

Some basic tests to verify sealing on memfds works as expected and guarantees the advertised semantics.
