  • c1b52739e   pkt_sched: namespace aware act_mirred ... Browse Code »

    Eric Dumazet pointed out that act_mirred needs to find the current net_ns,
    and struct net pointer is not provided in the call chain. His original
    patch made use of current->nsproxy->net_ns to find the network namespace,
    but this fails to work correctly for userspace code that makes use of
    netlink sockets in different network namespaces. Instead, pass the
    "struct net *" down along the call chain to where it is needed.

    This version removes the ifb changes as Eric has submitted that patch
    separately, but is otherwise identical to the previous version.

  • 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!
