  • 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

  • 7a2508e1b   mbcache2: rename to mbcache ... Browse Code »

    Since old mbcache code is gone, let's rename new code to mbcache since
    number 2 is now meaningless. This is just a mechanical replacement.

  • be0726d33   ext2: convert to mbcache2 ... Browse Code »

    The conversion is generally straightforward. We convert filesystem from
    a global cache to per-fs one. Similarly to ext4 the tricky part is that
    xattr block corresponding to found mbcache entry can get freed before we
    get buffer lock for that block. So we have to check whether the entry is
    still valid after getting the buffer lock.

  • 2a7dba391   fs/vfs/security: pass last path component to LSM on inode creation ... Browse Code »

    SELinux would like to implement a new labeling behavior of newly created
    inodes. We currently label new inodes based on the parent and the creating
    process. This new behavior would also take into account the name of the
    new object when deciding the new label. This is not the (supposed) full path,
    just the last component of the path.

    This is very useful because creating /etc/shadow is different than creating
    /etc/passwd but the kernel hooks are unable to differentiate these
    operations. We currently require that userspace realize it is doing some
    difficult operation like that and than userspace jumps through SELinux hoops
    to get things set up correctly. This patch does not implement new
    behavior, that is obviously contained in a seperate SELinux patch, but it
    does pass the needed name down to the correct LSM hook. If no such name
    exists it is fine to pass NULL.

  • 10f47e6a1   [PATCH] ext2: Enable atomic inode security labeling ... Browse Code »

    This patch modifies ext2 to call the inode_init_security LSM hook to obtain
    the security attribute for a newly created inode and to set the resulting
    attribute on the new inode. This parallels the existing processing for
    setting ACLs on newly created inodes.

    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!
