  • c7de2cf05   pkt_sched: gen_kill_estimator() rcu fixes ... Browse Code »

    gen_kill_estimator() API is incomplete or not well documented, since
    caller should make sure an RCU grace period is respected before
    freeing stats_lock.

    This was partially addressed in commit 5d944c640b4
    (gen_estimator: deadlock fix), but same problem exist for all
    gen_kill_estimator() users, if lock they use is not already RCU
    protected.

    A code review shows xt_RATEEST.c, act_api.c, act_police.c have this
    problem. Other are ok because they use qdisc lock, already RCU
    protected.

  • c1a8f1f1c   net: restore gnet_stats_basic to previous definition ... Browse Code »

    In 5e140dfc1fe87eae27846f193086724806b33c7d "net: reorder struct Qdisc
    for better SMP performance" the definition of struct gnet_stats_basic
    changed incompatibly, as copies of this struct are shipped to
    userland via netlink.

    Restoring old behavior is not welcome, for performance reason.

    Fix is to use a private structure for kernel, and
    teach gnet_stats_copy_basic() to convert from kernel to user land,
    using legacy structure (struct gnet_stats_basic)

    Based on a report and initial patch from Michael Spang.

  • c3bc7cff8   [NET_SCHED]: Kill CONFIG_NET_CLS_POLICE ... Browse Code »

    The NET_CLS_ACT option is now a full replacement for NET_CLS_POLICE,
    remove the old code. The config option will be kept around to select
    the equivalent NET_CLS_ACT options for a short time to allow easier
    upgrades.

  • 4bdf39911   [NET_SCHED]: Remove unnecessary stats_lock pointers ... Browse Code »

    Remove stats_lock pointers from qdisc-internal structures, in all cases
    it points to dev->queue_lock. The only case where it is necessary is for
    top-level qdiscs, where it might also point to dev->ingress_lock in case
    of the ingress qdisc. Also remove it from actions completely, it always
    points to the actions internal lock.

  • e9ce1cd3c   [PKT_SCHED]: Kill pkt_act.h inlining. ... Browse Code »

    This was simply making templates of functions and mostly causing a lot
    of code duplication in the classifier action modules.

    We solve this more cleanly by having a common "struct tcf_common" that
    hash worker functions contained once in act_api.c can work with.

    Callers work with real action objects that have the common struct
    plus their module specific struct members. You go from a common
    object to the higher level one using a "to_foo()" macro which makes
    use of container_of() to do the dirty work.

    This also kills off act_generic.h which was only used by act_simple.c
    and keeping it around was more work than the it's value.

    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!
