Now we are just going have the user configure one). Described in netdev01 paper: "Distributing Linux Traffic Control Classifier-Action Subsystem" Authors: Jamal Hadi Salim and Damascene M. Joachimpillai The original motivation and deployment of this work was to horizontally scale packet processing at scope of a chasis or rack. This means one could take a tc policy and split it across machines connected over L2. The paper refers to this as "pipeline stage indexing". Other use cases which evolved out of the original intent include but are not limited to carrying OAM information, carrying exception handling metadata, carrying programmed authentication and authorization information, encapsulating programmed compliance information, service IDs etc. Read the referenced paper for more details. The architecture allows for incremental updates for new metadatum support to cover different use cases. This patch set includes support for basic skb metadatum. Followup patches will have more examples of metadata and other features. v3 changes: Integrate with the new namespace changes Remove skbhash and queue mapping metadata (but keep their claim for ids) Integrate feedback from Cong Integrate feedback from Daniel v2 changes: Remove module option for an upper bound of metadata Integrate feedback from Cong Integrate feedback from Daniel Jamal Hadi Salim (3): introduce IFE action Support to encoding decoding skb mark on IFE action Support to encoding decoding skb prio on IFE action include/net/tc_act/tc_ife.h | 61 +++ include/uapi/linux/tc_act/tc_ife.h | 38 ++ net/sched/Kconfig | 22 + net/sched/Makefile | 3 + net/sched/act_ife.c | 883 +++++++++++++++++++++++++++++++++++++ net/sched/act_meta_mark.c | 79 ++++ net/sched/act_meta_skbprio.c | 76 ++++ 7 files changed, 1162 insertions(+) create mode 100644 include/net/tc_act/tc_ife.h create mode 100644 include/uapi/linux/tc_act/tc_ife.h create mode 100644 net/sched/act_ife.c create mode 100644 net/sched/act_meta_mark.c create mode 100644 net/sched/act_meta_skbprio.c -- 1.9.1
