  • 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

  • Cleanup, no functional changes.

    - __set_personality() always changes ->exec_domain/personality, the
    special case when ->exec_domain remains the same buys nothing but
    complicates the code. Unify both cases to simplify the code.

    - The -EINVAL check in sys_personality() was never right. If we assume
    that set_personality() can fail we should check the value it returns
    instead of verifying that task->personality was actually changed.

    Remove it. Before the previous patch it was possible to hit this case
    due to overflow problems, but this -EINVAL just indicated the kernel
    bug.

    OTOH, probably it makes sense to change lookup_exec_domain() to return
    ERR_PTR() instead of default_exec_domain if the search in exec_domains
    list fails, and report this error to the user-space. But this means
    another user-space change, and we have in-kernel users which need fixes.
    For example, PER_OSF4 falls into PER_MASK for unkown reason and nobody
    cares to register this domain.

  • task_struct->pesonality is "unsigned int", but sys_personality() paths use
    "unsigned long pesonality". This means that every assignment or
    comparison is not right. In particular, if this argument does not fit
    into "unsigned int" __set_personality() changes the caller's personality
    and then sys_personality() returns -EINVAL.

    Turn this argument into "unsigned int" and avoid overflows. Obviously,
    this is the user-visible change, we just ignore the upper bits. But this
    can't break the sane application.

    There is another thing which can confuse the poorly written applications.
    User-space thinks that this syscall returns int, not long. This means
    that the returned value can be negative and look like the error code. But
    note that libc won't be confused and thus errno won't be set, and with
    this patch the user-space can never get -1 unless sys_personality() really
    fails. And, most importantly, the negative RET != -1 is only possible if
    that app previously called personality(RET).

  • 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!
