2017-02-10	Merge branch 'act_pedit-relative-offset'	David S. Miller	4	-17/+245
	Amir Vadai says: ==================== net/sched: act_pedit: Use offset relative to conventional network headers Some FW/HW parser APIs are such that they need to get the specific header type (e.g IPV4 or IPV6, TCP or UDP) and not only the networking level (e.g network or transport). Enhancing the UAPI to allow for specifying that, would allow the same flows to be set into both SW and HW. This patchset also makes pedit more robust. Currently fields offset is specified by offset relative to the ip header, while using negative offsets for MAC layer fields. This series enables the user to set offset relative to the relevant header. Usage example: $ tc filter add dev enp0s9 protocol ip parent ffff: \ flower \ ip_proto tcp \ dst_port 80 \ action \ pedit munge ip ttl add 0xff \ pedit munge tcp dport set 8080 \ pipe action mirred egress redirect dev veth0 Will forward traffic destined to tcp dport 80, while modifying the destination port to 8080, and decreasing the ttl by one. I've uploaded a draft for the userspace [2] to make it easier to review and test the patchset. [1] - http://patchwork.ozlabs.org/patch/700909/ [2] - git: https://bitbucket.org/av42/iproute2.git branch: pedit Patchset was tested and applied on top of upstream commit bd092ad1463c ("Merge branch 'remove-__napi_complete_done'") Thanks, Amir Changes since V2: - Instead of reusing unused bits in existing uapi fields, using new netlink attributes for the new information. This way new/old user space and new/old kernel can live together without having misunderstandings. Changes since V1: - No changes - V1 was sent and didn't make it for 4.10. - You asked me [1] why did I use specific header names instead of layers (L2, L3...), and I explained that it is on purpose, this extra information is planned to be used by hardware drivers to offload the action. ==================== Signed-off-by: David S.

2017-02-10	net/act_pedit: Introduce 'add' operation	Amir Vadai	3	-4/+35
	This command could be useful to inc/dec fields. For example, to forward any TCP packet and decrease its TTL: $ tc filter add dev enp0s9 protocol ip parent ffff: \ flower ip_proto tcp \ action pedit munge ip ttl add 0xff pipe \ action mirred egress redirect dev veth0 In the example above, adding 0xff to this u8 field is actually decreasing it by one, since the operation is masked.

2017-02-10	net/act_pedit: Support using offset relative to the conventional network headers	Amir Vadai	3	-16/+208
	Extend pedit to enable the user setting offset relative to network headers. This change would enable to work with more complex header schemes (vs the simple IPv4 case) where setting a fixed offset relative to the network header is not enough. After this patch, the action has information about the exact header type and field inside this header. This information could be used later on for hardware offloading of pedit. Backward compatibility was being kept: 1. Old kernel <-> new userspace 2. New kernel <-> old userspace 3. add rule using new userspace <-> dump using old userspace 4. add rule using old userspace <-> dump using new userspace When using the extended api, new netlink attributes are being used. This way, operation will fail in (1) and (3) - and no malformed rule be added or dumped. Of course, new user space that doesn't need the new functionality can use the old netlink attributes and operation will succeed. Since action can support both api's, (2) should work, and it is easy to write the new user space to have (4) work. The action is having a strict check that only header types and commands it can handle are accepted. This way future additions will be much easier. Usage example: $ tc filter add dev enp0s9 protocol ip parent ffff: \ flower \ ip_proto tcp \ dst_port 80 \ action pedit munge tcp dport set 8080 pipe \ action mirred egress redirect dev veth0 Will forward tcp port whose original dest port is 80, while modifying the destination port to 8080.
