Simon Horman says: ==================== nfp: flower: add Geneve tunnel support John Hurley says: This patchset adds support for offloading the encap and decap of Geneve tunnels to the NFP. In both cases, specifying well known port 6081 is a requirement for rule offload. Geneve firmware support has been recently added, so the patchset includes the reading of a fw symbol that defines a bitmap of newly supported features. Geneve will only be offloaded if the fw supports it. The new symbol is added in fw r5646. Geneve option fields are not supported as either a match or an action due there current exclussion from TC flower. Because Geneve (as both a match and action) behaves the same as other udp tunnels such as VXLAN, generic functions are created that handle both Geneve and VXLAN. It is anticapated that these functions will be modified to support options in future patches. The removal of an unused variable 'tun_dst_mask' is included as a separate patch here. This does not affect functionality. Also included are modifications to the test framework to check that the new encap and decap features are functioning correctly. ==================== Signed-off-by:

Compile Geneve match fields for offloading to the NFP. The addition of Geneve overflows the 8 bit key_layer field, so apply extended metadata to the match cmsg allowing up to 32 more key_layer fields. Rather than adding new Geneve blocks, move the vxlan code to generic ipv4 udp tunnel structs and use these for both vxlan and Geneve. Matches are only supported when specifically mentioning well known port 6081. Geneve tunnel options are not yet included in the match. Only offload Geneve if the fw supports it - include check for this. Signed-off-by:

The tunnel dest IP is required for separate offload to the NFP. It is already verified that a dest IP must be present and must be an exact match in the flower rule. Therefore, we can just extract the IP from the generated offload rule and remove the unused mask variable. The function is then no longer required to return the IP separately. Because tun_dst is localised to tunnel matches, move the declaration to the tunnel if branch. Signed-off-by:

Introduce NETIF_F_GRO_HW feature flag for NICs that support hardware GRO. With this flag, we can now independently turn on or off hardware GRO when GRO is on. Previously, drivers were using NETIF_F_GRO to control hardware GRO and so it cannot be independently turned on or off without affecting GRO. Hardware GRO (just like GRO) guarantees that packets can be re-segmented by TSO/GSO to reconstruct the original packet stream. Logically, GRO_HW should depend on GRO since it a subset, but we will let individual drivers enforce this dependency as they see fit. Since NETIF_F_GRO is not propagated between upper and lower devices, NETIF_F_GRO_HW should follow suit since it is a subset of GRO. In other words, a lower device can independent have GRO/GRO_HW enabled or disabled and no feature propagation is required. This will preserve the current GRO behavior. This can be changed later if we decide to propagate GRO/ GRO_HW/RXCSUM from upper to lower devices. Cc: Ariel Elior <Ariel.Elior@cavium.com> Cc: everest-linux-l2@cavium.com Signed-off-by:

In some case, we want to know how many sockets are in use in different _net_ namespaces. It's a key resource metric. This patch add a member in struct netns_core. This is a counter for socket-inuse in the _net_ namespace. The patch will add/sub counter in the sk_alloc, sk_clone_lock and __sk_free. This patch will not counter the socket created in kernel. It's not very useful for userspace to know how many kernel sockets we created. The main reasons for doing this are that: 1. When linux calls the 'do_exit' for process to exit, the functions 'exit_task_namespaces' and 'exit_task_work' will be called sequentially. 'exit_task_namespaces' may have destroyed the _net_ namespace, but 'sock_release' called in 'exit_task_work' may use the _net_ namespace if we counter the socket-inuse in sock_release. 2. socket and sock are in pair. More important, sock holds the _net_ namespace. We counter the socket-inuse in sock, for avoiding holding _net_ namespace again in socket. It's a easy way to maintain the code. Signed-off-by:
