net/sched: pedit: make sure that offset is valid

2016-11-30T00:46:00+00:00

Add a validation function to make sure offset is valid:
1. Not below skb head (could happen when offset is negative).
2. Validate both 'offset' and 'at'.

net_sched: move tc_action into tcf_common

2016-07-26T04:49:19+00:00

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.

net_sched: add network namespace support for tc actions

2016-02-25T19:16:21+00:00

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.

act_pedit: check binding before calling tcf_hash_release()

2015-07-31T22:22:34+00:00

When we share an action within a filter, the bind refcnt
should increase, therefore we should not call tcf_hash_release().

net: sched: add percpu stats to actions

2015-07-08T20:50:41+00:00

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.
