  • 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

  • f53de1e9a   net: ipv6: use common fib_default_rule_pref ... Browse Code »

    This switches IPv6 policy routing to use the shared
    fib_default_rule_pref() function of IPv4 and DECnet. It is also used in
    multicast routing for IPv4 as well as IPv6.

    The motivation for this patch is a complaint about iproute2 behaving
    inconsistent between IPv4 and IPv6 when adding policy rules: Formerly,
    IPv6 rules were assigned a fixed priority of 0x3FFF whereas for IPv4 the
    assigned priority value was decreased with each rule added.

    Since then all users of the default_pref field have been converted to
    assign the generic function fib_default_rule_pref(), fib_nl_newrule()
    may just use it directly instead. Therefore get rid of the function
    pointer altogether and make fib_default_rule_pref() static, as it's not
    used outside fib_rules.c anymore.

  • 419df12fb   net: move fib_rules_unregister() under rtnl lock ... Browse Code »

    We have to hold rtnl lock for fib_rules_unregister()
    otherwise the following race could happen:

    fib_rules_unregister(): fib_nl_delrule():
    ... ...
    ... ops = lookup_rules_ops();
    list_del_rcu(&ops->list);
    list_for_each_entry(ops->rules) {
    fib_rules_cleanup_ops(ops); ...
    list_del_rcu(); list_del_rcu();
    }

    Note, net->rules_mod_lock is actually not needed at all,
    either upper layer netns code or rtnl lock guarantees
    we are safe.

  • 25239cee7   net: rtnetlink: decouple rtnetlink address families from real address families ... Browse Code »

    Decouple rtnetlink address families from real address families in socket.h to
    be able to add rtnetlink interfaces to code that is not a real address family
    without increasing AF_MAX/NPROTO.

    This will be used to add support for multicast route dumping from all tables
    as the proc interface can't be extended to support anything but the main table
    without breaking compatibility.

    This partialy undoes the patch to introduce independant families for routing
    rules and converts ipmr routing rules to a new rtnetlink family. Similar to
    that patch, values up to 127 are reserved for real address families, values
    above that may be used arbitrarily.

    fib_rules_register() duplicates the template passed to it without modification,
    mark the argument as const. Additionally the templates are only needed when
    instantiating a new namespace, so mark them as __net_initdata, which means
    they can be discarded when CONFIG_NET_NS=n.

  • e9c5158ac   net: Allow fib_rule_unregister to batch ... Browse Code »

    Refactor the code so fib_rules_register always takes a template instead
    of the actual fib_rules_ops structure that will be used. This is
    required for network namespace support so 2 out of the 3 callers already
    do this, it allows the error handling to be made common, and it allows
    fib_rules_unregister to free the template for hte caller.

    Modify fib_rules_unregister to use call_rcu instead of syncrhonize_rcu
    to allw multiple namespaces to be cleaned up in the same rcu grace
    period.

    This patch fixes a small memory leak. Default fib rules can be deleted by
    the user if the rule does not carry FIB_RULE_PERMANENT flag, f.e. by
    ip rule flush

    Such a rule will not be freed as the ref-counter has 2 on start and becomes
    clearly unreachable after removal.

  • e1701c68c   [NET]: Fix fib_rules compatibility breakage ... Browse Code »

    Based upon a patch from Patrick McHardy.

    The fib_rules netlink attribute policy introduced in 2.6.19 broke
    userspace compatibilty. When specifying a rule with "from all"
    or "to all", iproute adds a zero byte long netlink attribute,
    but the policy requires all addresses to have a size equal to
    sizeof(struct in_addr)/sizeof(struct in6_addr), resulting in a
    validation error.

    Check attribute length of FRA_SRC/FRA_DST in the generic framework
    by letting the family specific rules implementation provide the
    length of an address. Report an error if address length is non
    zero but no address attribute is provided. Fix actual bug by
    checking address length for non-zero instead of relying on
    availability of attribute.
