2016-09-22net/sched: act_vlan: Introduce TCA_VLAN_ACT_MODIFY vlan actionShmulik Ladkani1-1/+28
TCA_VLAN_ACT_MODIFY allows one to change an existing tag. It accepts same attributes as TCA_VLAN_ACT_PUSH (protocol, id, priority). If packet is vlan tagged, then the tag gets overwritten according to user specified attributes. For example, this allows user to replace a tag's vid while preserving its priority bits (as opposed to "action vlan pop pipe action vlan push").

2016-08-18net_sched: act_vlan: Add priority optionHadar Hen Zion1-2/+11
The current vlan push action supports only vid and protocol options. Add priority option. Example script that adds vlan push action with vid and priority: tc filter add dev veth0 protocol ip parent ffff: \ flower \ indev veth0 \ action vlan push id 100 priority 5 Signed-off-by: Hadar Hen Zion <hadarh@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2016-07-25net_sched: move tc_action into tcf_commonWANG Cong1-13/+15
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.

2016-02-25net_sched: add network namespace support for tc actionsWANG Cong1-6/+48
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.
