    becomes :

    Okay :) Here is the last round, before the night !

    Thanks again

    [RFC] pkt_sched: gen_estimator: Don't report fake rate estimators

    We currently send TCA_STATS_RATE_EST elements to netlink users, even if no estimator
    is running.

    # tc -s -d qdisc
    qdisc pfifo_fast 0: dev eth0 root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
    Sent 112833764978 bytes 1495081739 pkt (dropped 0, overlimits 0 requeues 0)
    rate 0bit 0pps backlog 0b 0p requeues 0

    User has no way to tell if the "rate 0bit 0pps" is a real estimation, or a fake
    one (because no estimator is active)

    After this patch, tc command output is :
    $ tc -s -d qdisc
    qdisc pfifo_fast 0: dev eth0 root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
    Sent 561075 bytes 1196 pkt (dropped 0, overlimits 0 requeues 0)
    backlog 0b 0p requeues 0

    We add a parameter to gnet_stats_copy_rate_est() function so that
    it can use gen_estimator_active(bstats, r), as suggested by Jarek.

    This parameter can be NULL if check is not necessary, (htb for
    example has a mandatory rate estimator)

  • 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.

  • 244e6c2d0   pkt_sched: gen_estimator: Optimize gen_estimator_active() ... Browse Code »

    Since all other gen_estimator functions use bstats and rate_est params
    together, and searching for them is optimized now, let's use this also
    in gen_estimator_active(). The return type of gen_estimator_active()
    is changed to bool, and gen_find_node() parameters to const, btw.

    In tcf_act_police_locate() a check for ACT_P_CREATED is added before
    calling gen_estimator_active().

  • c1b56878f   tc: policing requires a rate estimator ... Browse Code »

    Found that while trying average rate policing, it was possible to
    request average rate policing without a rate estimator. This results
    in no policing which is harmless but incorrect.

    Since policing could be setup in two steps, need to check
    in the kernel.

  • 1e90474c3   [NET_SCHED]: Convert packet schedulers from rtnetlink to new netlink API ... Browse Code »

    Convert packet schedulers to use the netlink API. Unfortunately a gradual
    conversion is not possible without breaking compilation in the middle or
    adding lots of casts, so this patch converts them all in one step. The
    patch has been mostly generated automatically with some minor edits to
    at least allow seperate conversion of classifiers and actions.

    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!
