  • 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

  • Reduce the uses of this unnecessary typedef.

    Done via perl script:

    $ git grep --name-only -w ctl_table net | \
    xargs perl -p -i -e '\
    sub trim { my ($local) = @_; $local =~ s/(^\s+|\s+$)//g; return $local; } \
    s/\b(?<!struct\s)ctl_table\b(\s*\*\s*|\s+\w+)/"struct ctl_table " . trim($1)/ge'

    Reflow the modified lines that now exceed 80 columns.

  • Now that sys_sysctl is a compatiblity wrapper around /proc/sys
    all sysctl strategy routines, and all ctl_name and strategy
    entries in the sysctl tables are unused, and can be
    revmoed.

    In addition neigh_sysctl_register has been modified to no longer
    take a strategy argument and it's callers have been modified not
    to pass one.

  • It's unused.

    It isn't needed -- read or write flag is already passed and sysctl
    shouldn't care about the rest.

    It _was_ used in two places at arch/frv for some reason.

  • I want to compile out proc_* and sysctl_* handlers totally and
    stub them to NULL depending on config options, however usage of &
    will prevent this, since taking adress of NULL pointer will break
    compilation.

    So, drop & in front of every ->proc_handler and every ->strategy
    handler, it was never needed in fact.

    them. In general ->strategy hook should know what it's doing, and don't
    do something tricky for which, say, pointer to original userspace array

  • The decnet includes two places to patch. The first one is
    the net/decnet table itself, and it is patched just like
    other subsystems in the first patch in this series.

    The second place is a bit more complex - it is the
    net/decnet/conf/xxx entries,. similar to those in
    ipv4/devinet.c and ipv6/addrconf.c. This code is made similar
    to those in ipv[46].

  • This patch makes most of the generic device layer network
    namespace safe. This patch makes dev_base_head a
    network namespace variable, and then it picks up
    a few associated variables. The functions:
    dev_getbyhwaddr
    dev_getfirsthwbytype
    dev_get_by_flags
    dev_get_by_name
    __dev_get_by_name
    dev_get_by_index
    __dev_get_by_index
    dev_ioctl
    dev_ethtool
    dev_load
    wireless_process_ioctl

    were modified to take a network namespace argument, and
    deal with it.

    vlan_ioctl_set and brioctl_set were modified so their
    hooks will receive a network namespace argument.

    So basically anthing in the core of the network stack that was
    affected to by the change of dev_base was modified to handle
    multiple network namespaces. The rest of the network stack was
    simply modified to explicitly use &init_net the initial network
    namespace. This can be fixed when those components of the network
    stack are modified to handle multiple network namespaces.

    For now the ifindex generator is left global.

    Fundametally ifindex numbers are per namespace, or else
    we will have corner case problems with migration when
    we get that far.

    At the same time there are assumptions in the network stack
    that the ifindex of a network device won't change. Making
    the ifindex number global seems a good compromise until
    the network stack can cope with ifindex changes when
    you change namespaces, and the like.

  • The semantic effect of insert_at_head is that it would allow new registered
    sysctl entries to override existing sysctl entries of the same name. Which is
    pain for caching and the proc interface never implemented.

    I have done an audit and discovered that none of the current users of
    register_sysctl care as (excpet for directories) they do not register
    duplicate sysctl entries.

    So this patch simply removes the support for overriding existing entries in
    the sys_sysctl interface since no one uses it or cares and it makes future
    enhancments harder.

  • The sysctl numbers used are unique so setting the insert_at_head flag does not
    succeed in overriding any sysctls, and is just confusing because it doesn't.
    Clear the flag.

  • The typedef for dn_address has been removed in favour of using __le16
    or __u16 directly as appropriate. All the DECnet header files are
    updated accordingly.

    The byte ordering of dn_eth2dn() and dn_dn2eth() are both changed
    since just about all their callers wanted network order rather than
    host order, so the conversion is now done in the functions themselves.

    Several missed endianess conversions have been picked up during the
    conversion process. The nh_gw field in struct dn_fib_info has been
    changed from a 32 bit field to 16 bits as it ought to be.

    One or two cases of using htons rather than dn_htons in the routing
    code have been found and fixed.

    There are still a few warnings to fix, but this patch deals with the
    important cases.
