  • 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.

  • 3fa21e07e   net: Remove unnecessary returns from void function()s ... Browse Code »

    This patch removes from net/ (but not any netfilter files)
    all the unnecessary return; statements that precede the
    last closing brace of void functions.

    It does not remove the returns that are immediately
    preceded by a label as gcc doesn't like that.

    Done via:
    $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
    xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

  • de6d5cdf8   net_sched: make cls_ops->change and cls_ops->delete optional ... Browse Code »

    Some schedulers don't support creating, changing or deleting classes.
    Make the respective callbacks optionally and consistently return
    -EOPNOTSUPP for unsupported operations, instead of currently either
    -EOPNOTSUPP, -ENOSYS or no error.

    In case of sch_prio and sch_multiq, the removed operations additionally
    checked for an invalid class. This is not necessary since the class
    argument can only orginate from ->get() or in case of ->change is 0
    for creation of new classes, in which case ->change() incorrectly
    returned -ENOENT.

    As a side-effect, this patch fixes a possible (root-only) NULL pointer
    function call in sch_ingress, which didn't implement a so far mandatory
    ->delete() operation.

  • c9f1d0389   net_sched: fix class grafting errno codes ... Browse Code »

    If the parent qdisc doesn't support classes, use EOPNOTSUPP.
    If the parent class doesn't exist, use ENOENT. Currently EINVAL
    is returned in both cases.

    Additionally check whether grafting is supported and remove a now
    unnecessary graft function from sch_ingress.

  • 72eb7bd26   [NET_SCHED]: sch_ingress: remove netfilter support ... Browse Code »

    Since the old policer code is gone, TC actions are needed for policing.
    The ingress qdisc can get packets directly from netif_receive_skb()
    in case TC actions are enabled or through netfilter otherwise, but
    since without TC actions there is no policer the only thing it actually
    does is count packets.

    Remove the netfilter support and always require TC actions.

    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.

    Spring cleaning time...

    There seems to be a lot of places in the network code that have
    extra bogus semicolons after conditionals. Most commonly is a
    bogus semicolon after: switch() { }

  • fd44de7cc   [NET_SCHED]: ingress: switch back to using ingress_lock ... Browse Code »

    Switch ingress queueing back to use ingress_lock. qdisc_lock_tree now locks
    both the ingress and egress qdiscs on the device. All changes to data that
    might be used on both ingress and egress needs to be protected by using
    qdisc_lock_tree instead of manually taking dev->queue_lock. Additionally
    the qdisc stats_lock needs to be initialized to ingress_lock for ingress
    qdiscs.

  • 27a884dc3   [SK_BUFF]: Convert skb->tail to sk_buff_data_t ... Browse Code »

    So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
    on 64bit architectures, allowing us to combine the 4 bytes hole left by the
    layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
    64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
    :-)

    Many calculations that previously required that skb->{transport,network,
    mac}_header be first converted to a pointer now can be done directly, being
    meaningful as offsets or pointers.

    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!
