[PATCH] kselftests: cgroup: Avoid the reuse of fd after it is deallocated

by Hewenliang

It is necessary to set fd to -1 when inotify_add_watch() fails in cg_prepare_for_wait. Otherwise the fd which has been closed in cg_prepare_for_wait may be misused in other functions such as cg_enter_and_wait_for_frozen and cg_freeze_wait.

[PATCH v4] selftests: add tests for clone3()

by Adrian Reber

This adds tests for clone3() with different values and sizes of struct clone_args. This selftest was initially part of of the clone3() with PID selftest. After that patch was almost merged Eugene sent out a couple of patches to fix problems with these test. This commit now only contains the clone3() selftest after the LPC decision to rework clone3() with PID to allow setting the PID in multiple PID namespaces including all of Eugene's patches.

[PATCH] selftests: Move kselftest_module.sh into kselftest/

by Kees Cook

The kselftest_module.sh file was not being installed by the Makefile "install" target, rendering the lib/*.sh tests nonfunction. This fixes that and takes the opportunity to move it into the kselftest/ subdirectory which is where the kselftest infrastructure bits are collecting.

[PATCH v2 00/18] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM

by John Hubbard

Hi, Changes since v1: * Changed the function signature of __huge_pt_done() from int to void. * Renamed __remove_refs_from_head() to put_compound_head(). * Improved the comment documentation in mm.h and gup.c * Merged Documentation/vm/pin_user_pages.rst into the "introduce FOLL_PIN" patch. * Fixed Documentation/vm/pin_user_pages.rst: * Fixed up a TODO about DAX. * 31, not 32 bits total are available for counting * Deleted some stale comments from the commit description of the VFIO patch. * Added Reviewed-by tags from Ira Weiny and Jens Axboe, and Acked-by from Björn Töpel. ====================================================================== Original cover letter (edited to fix up the patch description numbers) This applies cleanly to linux-next and mmotm, and also to linux.git if linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB case") is first applied there. This provides tracking of dma-pinned pages. This is a prerequisite to solving the larger problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], and in a remarkable number of email threads since about 2017. :) A new internal gup flag, FOLL_PIN is introduced, and thoroughly documented in the last patch's Documentation/vm/pin_user_pages.rst. I believe that this will provide a good starting point for doing the layout lease work that Ira Weiny has been working on. That's because these new wrapper functions provide a clean, constrained, systematically named set of functionality that, again, is required in order to even know if a page is "dma-pinned". In contrast to earlier approaches, the page tracking can be incrementally applied to the kernel call sites that, until now, have been simply calling get_user_pages() ("gup"). In other words, opt-in by changing from this: get_user_pages() (sets FOLL_GET) put_page() to this: pin_user_pages() (sets FOLL_PIN) put_user_page() Because there are interdependencies with FOLL_LONGTERM, a similar conversion as for FOLL_PIN, was applied. The change was from this: get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET) put_page() to this: pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM) put_user_page() ============================================================ Patch summary: * Patches 1-4: refactoring and preparatory cleanup, independent fixes (Patch 4: V4L2-core bug fix (can be separately applied)) * Patch 5: introduce pin_user_pages(), FOLL_PIN, but no functional changes yet * Patches 6-11: Convert existing put_user_page() callers, to use the new pin*() * Patch 12: Activate tracking of FOLL_PIN pages. * Patches 13-15: convert FOLL_LONGTERM callers * Patches: 16-17: gup_benchmark and run_vmtests support * Patch 18: enforce FOLL_LONGTERM as a gup-internal (only) flag ============================================================ Testing: * I've done some overall kernel testing (LTP, and a few other goodies), and some directed testing to exercise some of the changes. And as you can see, gup_benchmark is enhanced to exercise this. Basically, I've been able to runtime test the core get_user_pages() and pin_user_pages() and related routines, but not so much on several of the call sites--but those are generally just a couple of lines changed, each. Not much of the kernel is actually using this, which on one hand reduces risk quite a lot. But on the other hand, testing coverage is low. So I'd love it if, in particular, the Infiniband and PowerPC folks could do a smoke test of this series for me. Also, my runtime testing for the call sites so far is very weak: * io_uring: Some directed tests from liburing exercise this, and they pass. * process_vm_access.c: A small directed test passes. * gup_benchmark: the enhanced version hits the new gup.c code, and passes. * infiniband (still only have crude "IB pingpong" working, on a good day: it's not exercising my conversions at runtime...) * VFIO: compiles (I'm vowing to set up a run time test soon, but it's not ready just yet) * powerpc: it compiles... * drm/via: compiles... * goldfish: compiles... * net/xdp: compiles... * media/v4l2: compiles... ============================================================ Next: * Get the block/bio_vec sites converted to use pin_user_pages(). * Work with Ira and Dave Chinner to weave this together with the layout lease stuff. ============================================================ [1] Some slow progress on get_user_pages() (Apr 2, 2019): https://lwn.net/Articles/784574/ [2] DMA and get_user_pages() (LPC: Dec 12, 2018): https://lwn.net/Articles/774411/ [3] The trouble with get_user_pages() (Apr 30, 2018): https://lwn.net/Articles/753027/ John Hubbard (18): mm/gup: pass flags arg to __gup_device_* functions mm/gup: factor out duplicate code from four routines goldish_pipe: rename local pin_user_pages() routine media/v4l2-core: set pages dirty upon releasing DMA buffers mm/gup: introduce pin_user_pages*() and FOLL_PIN goldish_pipe: convert to pin_user_pages() and put_user_page() infiniband: set FOLL_PIN, FOLL_LONGTERM via pin_longterm_pages*() mm/process_vm_access: set FOLL_PIN via pin_user_pages_remote() drm/via: set FOLL_PIN via pin_user_pages_fast() fs/io_uring: set FOLL_PIN via pin_user_pages() net/xdp: set FOLL_PIN via pin_user_pages() mm/gup: track FOLL_PIN pages media/v4l2-core: pin_longterm_pages (FOLL_PIN) and put_user_page() conversion vfio, mm: pin_longterm_pages (FOLL_PIN) and put_user_page() conversion powerpc: book3s64: convert to pin_longterm_pages() and put_user_page() mm/gup_benchmark: support pin_user_pages() and related calls selftests/vm: run_vmtests: invoke gup_benchmark with basic FOLL_PIN coverage mm/gup: remove support for gup(FOLL_LONGTERM) Documentation/vm/index.rst | 1 + Documentation/vm/pin_user_pages.rst | 212 +++++++ arch/powerpc/mm/book3s64/iommu_api.c | 15 +- drivers/gpu/drm/via/via_dmablit.c | 2 +- drivers/infiniband/core/umem.c | 5 +- drivers/infiniband/core/umem_odp.c | 10 +- drivers/infiniband/hw/hfi1/user_pages.c | 4 +- drivers/infiniband/hw/mthca/mthca_memfree.c | 3 +- drivers/infiniband/hw/qib/qib_user_pages.c | 8 +- drivers/infiniband/hw/qib/qib_user_sdma.c | 2 +- drivers/infiniband/hw/usnic/usnic_uiom.c | 9 +- drivers/infiniband/sw/siw/siw_mem.c | 5 +- drivers/media/v4l2-core/videobuf-dma-sg.c | 10 +- drivers/platform/goldfish/goldfish_pipe.c | 35 +- drivers/vfio/vfio_iommu_type1.c | 15 +- fs/io_uring.c | 5 +- include/linux/mm.h | 142 ++++- include/linux/mmzone.h | 2 + include/linux/page_ref.h | 10 + mm/gup.c | 594 ++++++++++++++++---- mm/gup_benchmark.c | 81 ++- mm/huge_memory.c | 32 +- mm/hugetlb.c | 28 +- mm/memremap.c | 4 +- mm/process_vm_access.c | 28 +- mm/vmstat.c | 2 + net/xdp/xdp_umem.c | 4 +- tools/testing/selftests/vm/gup_benchmark.c | 28 +- tools/testing/selftests/vm/run_vmtests | 22 + 29 files changed, 1054 insertions(+), 264 deletions(-) create mode 100644 Documentation/vm/pin_user_pages.rst -- 2.23.0

[PATCH v3 linux-kselftest-test 0/6] kunit: support building core/tests as modules

by Alan Maguire

The current kunit execution model is to provide base kunit functionality and tests built-in to the kernel. The aim of this series is to allow building kunit itself and tests as modules. This in turn allows a simple form of selective execution; load the module you wish to test. In doing so, kunit itself (if also built as a module) will be loaded as an implicit dependency. Because this requires a core API modification - if a module delivers multiple suites, they must be declared with the kunit_test_suites() macro - we're proposing this patch set as a candidate to be applied to the test tree before too many kunit consumers appear. We attempt to deal with existing consumers in patch 4. Changes since v2: - moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan) (patch 1) - split out non-exported interfaces in try-catch-impl.h (Brendan) (patch 2) - added kunit_find_symbol() and KUNIT_INIT_*SYMBOL to lookup non-exported symbols. KUNIT_INIT_*SYMBOL() is defined so that a mismatch between local symbol definition and definition of symbol in target will trigger a compilation error when the object is compiled built-in (Brendan) (patches 3, 4) - removed #ifdef MODULE around module licenses (Randy, Brendan, Andy) (patch 4) - replaced kunit_test_suite() with kunit_test_suites() rather than supporting both (Brendan) (patch 4) - lookup sysctl_hung_task_timeout_secs as kunit may be built as a module and the symbol may not be available (patch 5) - fixed whitespace issues in doc (patch 6) Alan Maguire (6): kunit: move string-stream.h to lib/kunit/string-stream-impl.h kunit: hide unexported try-catch interface in try-catch-impl.h kunit: add kunit_find_symbol() function for symbol lookup kunit: allow kunit tests to be loaded as a module kunit: allow kunit to be loaded as a module kunit: update documentation to describe module-based build Documentation/dev-tools/kunit/faq.rst | 3 +- Documentation/dev-tools/kunit/index.rst | 3 + Documentation/dev-tools/kunit/usage.rst | 16 +++++ include/kunit/assert.h | 3 +- include/kunit/string-stream.h | 51 ------------- include/kunit/test.h | 123 +++++++++++++++++++++++++++++--- include/kunit/try-catch.h | 10 --- kernel/sysctl-test.c | 4 +- lib/Kconfig.debug | 2 +- lib/kunit/Kconfig | 6 +- lib/kunit/Makefile | 4 +- lib/kunit/assert.c | 9 +++ lib/kunit/example-test.c | 4 +- lib/kunit/string-stream-impl.h | 51 +++++++++++++ lib/kunit/string-stream-test.c | 46 ++++++++---- lib/kunit/string-stream.c | 3 +- lib/kunit/test-test.c | 50 ++++++++++--- lib/kunit/test.c | 49 +++++++++++++ lib/kunit/try-catch-impl.h | 23 ++++++ lib/kunit/try-catch.c | 6 ++ 20 files changed, 363 insertions(+), 103 deletions(-) delete mode 100644 include/kunit/string-stream.h create mode 100644 lib/kunit/string-stream-impl.h create mode 100644 lib/kunit/try-catch-impl.h -- 1.8.3.1

[PATCH] selftests: bpf: add missing object file to TEST_FILES

by Anders Roxell

When installing kselftests to its own directory and run the test_lwt_ip_encap.sh it will complain that test_lwt_ip_encap.o can't be found. Same with the test_tc_edt.sh test it will complain that test_tc_edt.o can't be found. $ ./test_lwt_ip_encap.sh starting egress IPv4 encap test Error opening object test_lwt_ip_encap.o: No such file or directory Object hashing failed! Cannot initialize ELF context! Failed to parse eBPF program: Invalid argument Rework to add test_lwt_ip_encap.o and test_tc_edt.o to TEST_FILES so the object file gets installed when installing kselftest.
