  • c26d61ea9   vfs: fix preadv64v2 and pwritev64v2 compat syscalls with offset == -1 ... Browse Code »

    [ Upstream commit cc4b1242d7e3b42eed73881fc749944146493e4f ]

    The preadv2 and pwritev2 syscalls are supposed to emulate the readv and
    writev syscalls when offset == -1. Therefore the compat code should
    check for offset before calling do_compat_preadv64 and
    do_compat_pwritev64. This is the case for the preadv2 and pwritev2
    syscalls, but handling of offset == -1 is missing in their 64-bit
    equivalent.

    This patch fixes that, calling do_compat_readv and do_compat_writev when
    offset == -1. This fixes the following glibc tests on x32:
    - misc/tst-preadvwritev2
    - misc/tst-preadvwritev64v2

  • a725356b6   vfs: swap names of {do,vfs}_clone_file_range() ... Browse Code »

    Commit 031a072a0b8a ("vfs: call vfs_clone_file_range() under freeze
    protection") created a wrapper do_clone_file_range() around
    vfs_clone_file_range() moving the freeze protection to former, so
    overlayfs could call the latter.

    The more common vfs practice is to call do_xxx helpers from vfs_xxx
    helpers, where freeze protecction is taken in the vfs_xxx helper, so
    this anomality could be a source of confusion.

    It seems that commit 8ede205541ff ("ovl: add reflink/copyfile/dedup
    support") may have fallen a victim to this confusion -
    ovl_clone_file_range() calls the vfs_clone_file_range() helper in the
    hope of getting freeze protection on upper fs, but in fact results in
    overlayfs allowing to bypass upper fs freeze protection.

    Swap the names of the two helpers to conform to common vfs practice
    and call the correct helpers from overlayfs and nfsd.

  • 6da2ec560   treewide: kmalloc() -> kmalloc_array() ... Browse Code »

    The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
    patch replaces cases of:

    kmalloc(a * b, gfp)

    with:
    kmalloc_array(a * b, gfp)

    as well as handling cases of:

    kmalloc(a * b * c, gfp)

    with:

    kmalloc(array3_size(a, b, c), gfp)

    as it's slightly less ugly than:

    kmalloc_array(array_size(a, b), c, gfp)

    This does, however, attempt to ignore constant size factors like:

    kmalloc(4 * 1024, gfp)

    though any constants defined via macros get caught up in the conversion.

    Any factors with a sizeof() of "unsigned char", "char", and "u8" were
    dropped, since they're redundant.

    The tools/ directory was manually excluded, since it has its own
    implementation of kmalloc().

    The Coccinelle script used for this was:

  • 36028d5dd   fs: add ksys_p{read,write}64() helpers; remove in-kernel calls to syscalls ... Browse Code »

    Using the ksys_p{read,write}64() wrappers allows us to get rid of
    in-kernel calls to the sys_pread64() and sys_pwrite64() syscalls.
    The ksys_ prefix denotes that this function is meant as a drop-in
    replacement for the syscall. In particular, it uses the same calling
    convention as sys_p{read,write}64().

    This patch is part of a series which removes in-kernel calls to syscalls.
    On this basis, the syscall entry path can be streamlined. For details, see

    Pull iov_iter updates from Al Viro:

    - bio_{map,copy}_user_iov() series; those are cleanups - fixes from the
    same pile went into mainline (and stable) in late September.

    - fs/iomap.c iov_iter-related fixes

    - new primitive - iov_iter_for_each_range(), which applies a function
    to kernel-mapped segments of an iov_iter.

    Usable for kvec and bvec ones, the latter does kmap()/kunmap() around
    the callback. _Not_ usable for iovec- or pipe-backed iov_iter; the
    latter is not hard to fix if the need ever appears, the former is by
    design.

    Another related primitive will have to wait for the next cycle - it
    passes page + offset + size instead of pointer + size, and that one
    will be usable for everything _except_ kvec. Unfortunately, that one
    didn't get exposure in -next yet, so...

    - a bit more lustre iov_iter work, including a use case for
    iov_iter_for_each_range() (checksum calculation)

    - vhost/scsi leak fix in failure exit

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

    Pull core block/IO updates from Jens Axboe:
    "This is the main pull request for the block layer for 4.13. Not a huge
    round in terms of features, but there's a lot of churn related to some
    core cleanups.

    Note this depends on the UUID tree pull request, that Christoph
    already sent out.

    This pull request contains:

    - A series from Christoph, unifying the error/stats codes in the
    block layer. We now use blk_status_t everywhere, instead of using
    different schemes for different places.

    - Also from Christoph, some cleanups around request allocation and IO
    scheduler interactions in blk-mq.

    - And yet another series from Christoph, cleaning up how we handle
    and do bounce buffering in the block layer.

    - A blk-mq debugfs series from Bart, further improving on the support
    we have for exporting internal information to aid debugging IO
    hangs or stalls.

    - Also from Bart, a series that cleans up the request initialization
    differences across types of devices.

    - A series from Goldwyn Rodrigues, allowing the block layer to return
    failure if we will block and the user asked for non-blocking.

    - Patch from Hannes for supporting setting loop devices block size to
    that of the underlying device.

    - Two series of patches from Javier, fixing various issues with
    lightnvm, particular around pblk.

    - A series from me, adding support for write hints. This comes with
    NVMe support as well, so applications can help guide data placement
    on flash to improve performance, latencies, and write
    amplification.

    - A series from Ming, improving and hardening blk-mq support for
    stopping/starting and quiescing hardware queues.

    - Two pull requests for NVMe updates. Nothing major on the feature
    side, but lots of cleanups and bug fixes. From the usual crew.

    - A series from Neil Brown, greatly improving the bio rescue set
    support. Most notably, this kills the bio rescue work queues, if we
    don't really need them.

    - Lots of other little bug fixes that are all over the place"
