  • fib_rules_ops contains operations and the list of configured rules. ops will
    become per/namespace soon, so we need them to be known in the default_pref

  • The patch extends the different fib rules API in order to pass the
    network namespace pointer. That will allow to access the different
    tables from a namespace relative object. As usual, the pointer to the
    init_net variable is passed as parameter so we don't break the
    network.

  • When the fib_rules initialization finished, no return code is provided
    so there is no way to know, for the caller, if the initialization has
    been successful or has failed. This patch fix that.

  • 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.

  • The results of FIB rules lookups are cached in the routing cache
    except for IPv6 as no such cache exists. So far, it was the
    responsibility of the user to flush the cache after modifying any
    rules. This lead to many false bug reports due to misunderstanding
    of this concept.

    This patch automatically flushes the route cache after inserting
    or deleting a rule.

    Thanks to Muli Ben-Yehuda for catching a bug
    in the previous patch.

  • This patch adds a new rule action FR_ACT_GOTO which allows
    to skip a set of rules by jumping to another rule. The rule
    to jump to is specified via the FRA_GOTO attribute which
    carries a rule preference.

    Referring to a rule which doesn't exists is explicitely allowed.
    Such goto rules are marked with the flag FIB_RULE_UNRESOLVED
    and will act like a rule with a non-matching selector. The rule
    will become functional as soon as its target is present.

    The goto action enables performance optimizations by reducing
    the average number of rules that have to be passed per lookup.

    Example:
    0: from all lookup local
    40: not from all to 192.168.23.128 goto 32766
    41: from all fwmark 0xa blackhole
    42: from all fwmark 0xff blackhole
    32766: from all lookup main

  • Implements a unified, protocol independant rules dumping function
    which is capable of both, dumping a specific protocol family or
    all of them. This speeds up dumping as less lookups are required.

  • 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.
