  • a85a970af   net_sched: move tc_action into tcf_common ... Browse Code »

    struct tc_action is confusing, currently we use it for two purposes:
    1) Pass in arguments and carry out results from helper functions
    2) A generic representation for tc actions

    The first one is error-prone, since we need to make sure we don't
    miss anything. This patch aims to get rid of this use, by moving
    tc_action into tcf_common, so that they are allocated together
    in hashtable and can be cast'ed easily.

    And together with the following patch, we could really make
    tc_action a generic representation for all tc actions and each
    type of action can inherit from it.

    The nf_conntrack_core.c fix in 'net' is not relevant in 'net-next'
    because we no longer have a per-netns conntrack hash.

    The ip_gre.c conflict as well as the iwlwifi ones were cases of
    overlapping changes.

  • 5e1567aeb   net sched: skbedit action fix late binding ... Browse Code »

    The process below was broken and is fixed with this patch.

    //add a skbedit action and give it an instance id of 1
    sudo tc actions add action skbedit mark 10 index 1
    //create a filter which binds to skbedit action id 1
    sudo tc filter add dev $DEV parent ffff: protocol ip prio 1 u32\
    match ip dst 17.0.0.1/32 flowid 1:10 action skbedit index 1

    Message before fix was:
    RTNETLINK answers: Invalid argument
    We have an error talking to the kernel

  • ddf97ccdd   net_sched: add network namespace support for tc actions ... Browse Code »

    Currently tc actions are stored in a per-module hashtable,
    therefore are visible to all network namespaces. This is
    probably the last part of the tc subsystem which is not
    aware of netns now. This patch makes them per-netns,
    several tc action API's need to be adjusted for this.

    The tc action API code is ugly due to historical reasons,
    we need to refactor that code in the future.

    Reuse existing percpu infrastructure John Fastabend added for qdisc.

    This patch adds a new cpustats parameter to tcf_hash_create() and all
    actions pass false, meaning this patch should have no effect yet.

  • 1a29321ed   net_sched: act: Dont increment refcnt on replace ... Browse Code »

    This is a bug fix. The existing code tries to kill many
    birds with one stone: Handling binding of actions to
    filters, new actions and replacing of action
    attributes. A simple test case to illustrate:

    XXXX
    moja@fe1:~$ sudo tc actions add action drop index 12
    moja@fe1:~$ actions get action gact index 12
    action order 1: gact action drop
    random type none pass val 0
    index 12 ref 1 bind 0
    moja@fe1:~$ sudo tc actions replace action ok index 12
    moja@fe1:~$ actions get action gact index 12
    action order 1: gact action drop
    random type none pass val 0
    index 12 ref 2 bind 0
    XXXX

    The above shows the refcounf being wrongly incremented on replace.
    There are more complex scenarios with binding of actions to filters
    that i am leaving out that didnt work as well...

    Several files refer to an old address for the Free Software Foundation
    in the file header comment. Resolve by replacing the address with
    the URL so that we do not have to keep

  • 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.

  • bfe0d0298   net_sched: factorize qdisc stats handling ... Browse Code »

    HTB takes into account skb is segmented in stats updates.
    Generalize this to all schedulers.

    They should use qdisc_bstats_update() helper instead of manipulating
    bstats.bytes and bstats.packets

    Add bstats_update() helper too for classes that use
    gnet_stats_basic_packed fields.

    Note : Right now, TCQ_F_CAN_BYPASS shortcurt can be taken only if no
    stab is setup on qdisc.

    We leak at least 32bits of kernel memory to user land in tc dump,
    because we dont init all fields (capab ?) of the dumped structure.

    Use C99 initializers so that holes and non explicit fields are zeroed.
