net_sched: get rid of struct tcf_common

2016-07-26T04:49:20Z

After the previous patch, struct tc_action should be enough to represent the generic tc action, tcf_common is not necessary any more. This patch gets rid of it to make tc action code more readable. Cc: Jamal Hadi Salim Signed-off-by: Cong Wang Signed-off-by: David S. Miller

net_sched: move tc_action into tcf_common

2016-07-26T04:49:19Z

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: act_mirred: Add helper inlines to access tcf_mirred info.

2016-07-25T06:12:00Z

The helper function is_tcf_mirred_mirror helps finding whether an action struct is of type mirred and is configured to be of type mirror. Signed-off-by: Yotam Gigi Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

net sched actions: skbedit add support for mod-ing skb pkt_type

2016-07-04T22:11:14Z

Extremely useful for setting packet type to host so i dont have to modify the dst mac address using pedit (which requires that i know the mac address) Example usage: tc filter add dev eth0 parent ffff: protocol ip pref 9 u32 \ match ip src 5.5.5.5/32 \ flowid 1:5 action skbedit ptype host This will tag all packets incoming from 5.5.5.5 with type PACKET_HOST Signed-off-by: Jamal Hadi Salim Acked-by: Daniel Borkmann Signed-off-by: David S.

Several cases of overlapping changes, except the packet scheduler conflicts which deal with the addition of the free list parameter to qdisc_enqueue(). Signed-off-by: David S. Miller

act_ife: only acquire tcf_lock for existing actions

2016-06-23T16:02:36Z

Alexey reported that we have GFP_KERNEL allocation when holding the spinlock tcf_lock. Actually we don't have to take that spinlock for all the cases, especially for the new one we just create. To modify the existing actions, we still need this spinlock to make sure the whole update is atomic. For net-next, we can get rid of this spinlock because we already hold the RTNL lock on slow path, and on fast path we can use RCU to protect the metalist. Joint work with Jamal.

net/sched: Macro instead of CONFIG_NET_CLS_ACT ifdef

2016-03-10T21:24:02Z

Introduce the macros tc_no_actions and tc_for_each_action to make code clearer. Extracted struct tc_action out of the ifdef to make calls to is_tcf_gact_shot() and similar functions valid, even when it is a nop.
