[PATCH v8 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter

by Mina Almasry

These counters will track hugetlb reservations rather than hugetlb memory faulted in. This patch only adds the counter, following patches add the charging and uncharging of the counter. Problem: Currently tasks attempting to allocate more hugetlb memory than is available get a failure at mmap/shmget time. This is thanks to Hugetlbfs Reservations [1]. However, if a task attempts to allocate hugetlb memory only more than its hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call, but will SIGBUS the task when it attempts to fault the memory in. We have developers interested in using hugetlb_cgroups, and they have expressed dissatisfaction regarding this behavior. We'd like to improve this behavior such that tasks violating the hugetlb_cgroup limits get an error on mmap/shmget time, rather than getting SIGBUS'd when they try to fault the excess memory in. The underlying problem is that today's hugetlb_cgroup accounting happens at hugetlb memory *fault* time, rather than at *reservation* time. Thus, enforcing the hugetlb_cgroup limit only happens at fault time, and the offending task gets SIGBUS'd. Proposed Solution: A new page counter named hugetlb.xMB.reservation_[limit|usage]_in_bytes. This counter has slightly different semantics than hugetlb.xMB.[limit|usage]_in_bytes: - While usage_in_bytes tracks all *faulted* hugetlb memory, reservation_usage_in_bytes tracks all *reserved* hugetlb memory and hugetlb memory faulted in without a prior reservation. - If a task attempts to reserve more memory than limit_in_bytes allows, the kernel will allow it to do so. But if a task attempts to reserve more memory than reservation_limit_in_bytes, the kernel will fail this reservation. This proposal is implemented in this patch series, with tests to verify functionality and show the usage. We also added cgroup-v2 support to hugetlb_cgroup so that the new use cases can be extended to v2. Alternatives considered: 1. A new cgroup, instead of only a new page_counter attached to the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code duplication with hugetlb_cgroup. Keeping hugetlb related page counters under hugetlb_cgroup seemed cleaner as well. 2. Instead of adding a new counter, we considered adding a sysctl that modifies the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at reservation time rather than fault time. Adding a new page_counter seems better as userspace could, if it wants, choose to enforce different cgroups differently: one via limit_in_bytes, and another via reservation_limit_in_bytes. This could be very useful if you're transitioning how hugetlb memory is partitioned on your system one cgroup at a time, for example. Also, someone may find usage for both limit_in_bytes and reservation_limit_in_bytes concurrently, and this approach gives them the option to do so. Testing: - Added tests passing. - libhugetlbfs tests mostly passing, but some tests have trouble with and without this patch series.

[PATCH 00/19] pin_user_pages(): reduced-risk series for Linux 5.5

by John Hubbard

Hi, Here is a set of well-reviewed (expect for one patch), lower-risk items that can go into Linux 5.5. The one patch that wasn't reviewed is the powerpc conversion, and it's still at this point a no-op, because tracking isn't yet activated. This is based on linux-next: b9d3d01405061bb42358fe53f824e894a1922ced ("Add linux-next specific files for 20191122"). This is essentially a cut-down v8 of "mm/gup: track dma-pinned pages: FOLL_PIN" [1], and with one of the VFIO patches split into two patches. The idea here is to get this long list of "noise" checked into 5.5, so that the actual, higher-risk "track FOLL_PIN pages" (which is deferred: not part of this series) will be a much shorter patchset to review. For the v4l2-core changes, I've left those here (instead of sending them separately to the -media tree), in order to get the name change done now (put_user_page --> unpin_user_page). However, I've added a Cc stable, as recommended during the last round of reviews. Here are the relevant notes from the original cover letter, edited to match the current situation: This is a prerequisite to tracking dma-pinned pages. That in turn 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() [1] https://lore.kernel.org/r/20191121071354.456618-1-jhubbard@nvidia.com thanks, John Hubbard NVIDIA Dan Williams (1): mm: Cleanup __put_devmap_managed_page() vs ->page_free() John Hubbard (18): mm/gup: factor out duplicate code from four routines mm/gup: move try_get_compound_head() to top, fix minor issues goldish_pipe: rename local pin_user_pages() routine mm: fix get_user_pages_remote()'s handling of FOLL_LONGTERM vfio: fix FOLL_LONGTERM use, simplify get_user_pages_remote() call mm/gup: introduce pin_user_pages*() and FOLL_PIN goldish_pipe: convert to pin_user_pages() and put_user_page() IB/{core,hw,umem}: set FOLL_PIN via pin_user_pages*(), fix up ODP 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() media/v4l2-core: set pages dirty upon releasing DMA buffers media/v4l2-core: pin_user_pages (FOLL_PIN) and put_user_page() conversion vfio, mm: pin_user_pages (FOLL_PIN) and put_user_page() conversion powerpc: book3s64: convert to pin_user_pages() and put_user_page() mm/gup_benchmark: use proper FOLL_WRITE flags instead of hard-coding "1" mm, tree-wide: rename put_user_page*() to unpin_user_page*() Documentation/core-api/index.rst | 1 + Documentation/core-api/pin_user_pages.rst | 233 ++++++++++++++ arch/powerpc/mm/book3s64/iommu_api.c | 12 +- drivers/gpu/drm/via/via_dmablit.c | 6 +- drivers/infiniband/core/umem.c | 4 +- drivers/infiniband/core/umem_odp.c | 13 +- drivers/infiniband/hw/hfi1/user_pages.c | 4 +- drivers/infiniband/hw/mthca/mthca_memfree.c | 8 +- drivers/infiniband/hw/qib/qib_user_pages.c | 4 +- drivers/infiniband/hw/qib/qib_user_sdma.c | 8 +- drivers/infiniband/hw/usnic/usnic_uiom.c | 4 +- drivers/infiniband/sw/siw/siw_mem.c | 4 +- drivers/media/v4l2-core/videobuf-dma-sg.c | 8 +- drivers/nvdimm/pmem.c | 6 - drivers/platform/goldfish/goldfish_pipe.c | 35 +-- drivers/vfio/vfio_iommu_type1.c | 35 +-- fs/io_uring.c | 6 +- include/linux/mm.h | 77 +++-- mm/gup.c | 332 +++++++++++++------- mm/gup_benchmark.c | 9 +- mm/memremap.c | 80 ++--- mm/process_vm_access.c | 28 +- net/xdp/xdp_umem.c | 4 +- tools/testing/selftests/vm/gup_benchmark.c | 6 +- 24 files changed, 642 insertions(+), 285 deletions(-) create mode 100644 Documentation/core-api/pin_user_pages.rst -- 2.24.0

[PATCH] selftests: Load settings from subdirs

by Kees Cook

If settings files are present in upper directories of a test directory, load those first before the local settings. This allows a top-level directory to define settings for subdirectories while still allowing the subdirectories to override them on a per-directory basis.

[PATCH linux-kselftest/test v3] Documentation: kunit: add documentation for kunit_tool

by Brendan Higgins

Add documentation for the Python script used to build, run, and collect results from the kernel known as kunit_tool. kunit_tool (tools/testing/kunit/kunit.py) was already added in previous commits.
