sch_hhf: fix return value of hhf_drop()

2015-10-11T11:49:33+00:00

Similar to commit c0afd9ce4d6a ("fq_codel: fix return value of fq_codel_drop()")
->drop() is supposed to return the number of bytes it dropped,
but hhf_drop () returns the id of the bucket where it drops
a packet from.

act_mirred: clear sender cpu before sending to tx

2015-10-08T11:59:04+00:00

Similar to commit c29390c6dfee ("xps: must clear sender_cpu before forwarding")
the skb->sender_cpu needs to be cleared when moving from Rx
Tx, otherwise kernel could crash.

act_mirred: fix a race condition on mirred_list

2015-10-05T13:30:33+00:00

After commit 1ce87720d456 ("net: sched: make cls_u32 lockless")
we began to release tc actions in a RCU callback. However,
mirred action relies on RTNL lock to protect the global
mirred_list, therefore we could have a race condition
between RCU callback and netdevice event, which caused
a list corruption as reported by Vinson.

Instead of relying on RTNL lock, introduce a spinlock to
protect this list.

Note, in non-bind case, it is still called with RTNL lock,
therefore should disable BH too.

net: revert "net_sched: move tp->root allocation into fw_init()"

2015-09-24T21:33:30+00:00

fw filter uses tp->root==NULL to check if it is the old method,
so it doesn't need allocation at all in this case. This patch
reverts the offending commit and adds some comments for old
method to make it obvious.

flow_dissector: Add flags argument to skb_flow_dissector functions

The flags argument will allow control of the dissection process (for
instance whether to parse beyond L3).

net: sched: don't break line in tc_classify loop notification

2015-08-28T21:01:15+00:00

Just some minor noise follow-up to address some stylistic issues of
commit 3b3ae880266d ("net: sched: consolidate tc_classify{,_compat}").
Accidentally v1 instead of v2 of that commit got applied, so this
patch adds the relative diff.

net: sched: simplify attach_one_default_qdisc()

2015-08-28T00:14:30+00:00

Now that noqueue qdisc can be attached just like any other qdisc, no
special treatment is necessary anymore when attaching it as default
qdisc.

This change has the added benefit that 'tc qdisc show' prints noqueue
instead of nothing for devices defaulting to noqueue.

net: sched: register noqueue qdisc

2015-08-28T00:14:30+00:00

This way users can attach noqueue just like any other qdisc using tc
without having to mess with tx_queue_len first.
