  • 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

  • 74d46992e   block: replace bi_bdev with a gendisk pointer and partitions index ... Browse Code »

    This way we don't need a block_device structure to submit I/O. The
    block_device has different life time rules from the gendisk and
    request_queue and is usually only available when the block device node
    is open. Other callers need to explicitly create one (e.g. the lightnvm
    passthrough code, or the new nvme multipathing code).

    For the actual I/O path all that we need is the gendisk, which exists
    once per block device. But given that the block layer also does
    partition remapping we additionally need a partition index, which is
    used for said remapping in generic_make_request.

    Note that all the block drivers generally want request_queue or
    sometimes the gendisk, so this removes a layer of indirection all
    over the stack.

  • 4f024f379   block: Abstract out bvec iterator ... Browse Code »

    Immutable biovecs are going to require an explicit iterator. To
    implement immutable bvecs, a later patch is going to add a bi_bvec_done
    member to this struct; for now, this patch effectively just renames
    things.

    Commit 6596528e391a ("hfsplus: ensure bio requests are not smaller than
    the hardware sectors") changed the pointers used for volume header
    allocations but failed to free the correct pointers in the error path
    path of hfsplus_fill_super() and hfsplus_read_wrapper.

    The second hunk came from a separate patch by Pavel Ivanov.

  • 52399b171   hfsplus: use raw bio access for the volume headers ... Browse Code »

    The hfsplus backup volume header is located two blocks from the end of
    the device. In case of device sizes that are not 4k aligned this means
    we can't access it using buffer_heads when using the default 4k block
    size.

    Switch to using raw bios to read/write all buffer headers. We were not
    relying on any caching behaviour of the buffer heads anyway. Additionally
    always read in the backup volume header during mount to verify that we
    can actually read it.

    HFSPLUS_SB doesn't return a pointer to the hfsplus-specific superblock
    information like all other FOO_SB macros, but dereference the pointer in a way
    that made it look like a direct struct derefence. This only works as long
    as the HFSPLUS_SB macro is used directly and prevents us from keepig a local
    hfsplus_sb_info pointer. Fix the calling convention and introduce a local
    sbi variable in all functions that use it constantly.

  • 5c36fe3d8   hfsplus: refuse to mount volumes larger than 2TB ... Browse Code »

    As found in , hfsplus is using type u32
    rather than sector_t for some sector number calculations.

    In particular, hfsplus_get_block() does:

    u32 ablock, dblock, mask;
    ...
    map_bh(bh_result, sb, (dblock << HFSPLUS_SB(sb).fs_shift) + HFSPLUS_SB(sb).blockoffset + (iblock & mask));

    I am not confident that I can find and fix all cases where a sector number
    may be truncated. For now, avoid data loss by refusing to mount HFS+
    volumes with more than 2^32 sectors (2TB).

  • 733482e44   [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason ... Browse Code »

    This patch removes almost all inclusions of linux/version.h. The 3
    #defines are unused in most of the touched files.

    A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
    unfortunatly in linux/version.h.

    There are also lots of #ifdef for long obsolete kernels, this was not
    touched. In a few places, the linux/version.h include was move to where
    the LINUX_VERSION_CODE was used.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
