net: Allow fib_rule_unregister to batch

2009-12-03T20:22:55+00:00

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.

net 03/05: fib_rules: add oif classification

2009-12-03T20:14:36+00:00

    net: fib_rules: add oif classification

    Support routing table lookup based on the flow's oif. This is useful to
    classify packets originating from sockets bound to interfaces differently.

    The route cache already includes the oif and needs no changes.

net 01/05: fib_rules: rearrange struct fib_rule

2009-12-03T20:14:34+00:00

    net: fib_rules: rearrange struct fib_rule

    The ifname member is only used to resolve interface names and is not needed
    during rule lookups. The target and ctarget members however are used during
    rule lookups and are currently located in a second cacheline.

    Move ifname further to the end to make sure both target and ctarget are
    located in the same cacheline as other members used during rule lookups.

    The layout on 64 bit changes from:

    struct fib_rule {
    	...
            u32                        table;                /*    56     4 */
            u8                         action;               /*    60     1 */

            /* XXX 3 bytes hole, try to pack */

            /* --- cacheline 1 boundary (64 bytes) --- */
            u32                        target;               /*    64     4 */

            /* XXX 4 bytes hole, try to pack */

            struct fib_rule *          ctarget;              /*    72     8 */
            struct rcu_head            rcu;                  /*    80    16 */
            struct net *               fr_net;               /*    96     8 */
    };

    to:

    struct fib_rule {
    	...
            u32                        table;                /*    40     4 */
            u8                         action;               /*    44     1 */

            /* XXX 3 bytes hole, try to pack */

            u32                        target;               /*    48     4 */

            /* XXX 4 bytes hole, try to pack */

            struct fib_rule *          ctarget;              /*    56     8 */
            /* --- cacheline 1 boundary (64 bytes) --- */
            char                       ifname[16];           /*    64    16 */
            struct rcu_head            rcu;                  /*    80    16 */
            struct net *               fr_net;               /*    96     8 */
