2019-11-13net/mlx5: Add new chain for netfilter flow table offloadPaul Blakey3-6/+15
Netfilter tables (nftables) implements a software datapath that comes after tc ingress datapath. The datapath supports offloading such rules via the flow table offload API. This API is currently only used by NFT and it doesn't provide the global priority in regards to tc offload, so we assume offloading such rules must come after tc. It does provide a flow table priority parameter, so we need to provide some supported priority range. For that, split fastpath prio to two, flow table offload and tc offload, with one dedicated priority chain for flow table offload. Next patch will re-use the multi chain API to access this chain by allowing access to this chain by the fdb_sub_namespace.

2019-11-13net/mlx5: Accumulate levels for chains prio namespacesPaul Blakey2-2/+10
Tc chains are implemented by creating a chained prio steering type, and inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each of those has a list of priorities. Currently, all namespaces in a prio start at the parent prio level. But since we can jump from chain (namespace) to another chain in the same prio, we need the levels for higher chains to be higher as well. So we created unused prios to account for levels in previous namespaces. Fix that by accumulating the namespaces levels if we are inside a chained type prio, and removing the unused prios.

Matthias Schiffer says: ==================== Implement get_link_ksettings for VXLAN and bridge Mesh routing protocol batman-adv (in particular the new BATMAN_V algorithm) uses the link speed reported by get_link_ksettings to determine a path metric for wired links. In the mesh framework Gluon [1], we layer VXLAN and sometimes bridge interfaces on our Ethernet links. These patches implement get_link_ksettings for these two interface types. While this is obviously not accurate for bridges with multiple active ports, it's much better than having no estimate at all (and in the particular setup of Gluon, bridges with a single port aren't completely uncommon).

It is possible for a switch driver to use NET_DSA_TAG_8021Q as a valid DSA tagging protocol since it registers itself as such, unfortunately since there are not xmit or rcv functions provided, the lack of a xmit() function will lead to a NPD in dsa_slave_xmit() to start with. net/dsa/tag_8021q.c is only comprised of a set of helper functions at the moment, but is not a fully autonomous or functional tagging "driver" (though it could become later on). We do not have any users of NET_DSA_TAG_8021Q so now is a good time to make sure there are not issues being encountered by making this file strictly a place holder for helper functions.

Pablo Neira Ayuso says: ==================== netfilter flowtable hardware offload The following patchset adds hardware offload support for the flowtable infrastructure [1]. This infrastructure provides a fast datapath for the classic Linux forwarding path that users can enable through policy, eg. table inet x { flowtable f { hook ingress priority 10 devices = { eth0, eth1 } flags offload } chain y { type filter hook forward priority 0; policy accept; ip protocol tcp flow offload @f } } This example above enables the fastpath for TCP traffic between devices eth0 and eth1. Users can turn on the hardware offload through the 'offload' flag from the flowtable definition. If this new flag is not specified, the software flowtable datapath is used. This patchset is composed of 4 preparation patches: room to extend this infrastructure, eg. accelerate bridge forwarding. And 2 patches to add the hardware offload control and data planes: hardware offload. This includes a new NFTA_FLOWTABLE_FLAGS netlink attribute to convey the optional NF_FLOWTABLE_HW_OFFLOAD flag. API available at net/core/flow_offload.h to represent the flow through two flow_rule objects to configure an exact 5-tuple matching on each direction plus the corresponding forwarding actions, that is, the MAC address, NAT and checksum updates; and port redirection in order to configure the hardware datapath. This patch only supports for IPv4 support and statistics collection for flow aging as an initial step. This patchset introduces a new flow_block callback type that needs to be set up to configure the flowtable hardware offload. The first client of this infrastructure follows up after this batch. I would like to thank Mellanox for developing the first upstream driver to use this infrastructure. [1] Documentation/networking/nf_flowtable.txt ==================== Signed-off-by: David S.

2019-11-12net/sched: actions: remove unused 'order'Davide Caratti2-2/+0
after commit 4097e9d250fb ("net: sched: don't use tc_action->order during action dump"), 'act->order' is initialized but then it's no more read, so we can just remove this member of struct tc_action.

2019-11-12Merge branch 'Update-devlink-binary-output'David S. Miller5-36/+27
Aya Levin says: ==================== Update devlink binary output This series changes the devlink binary interface: -The first patch forces binary values to be enclosed in an array. In addition, devlink_fmsg_binary_pair_put breaks the binary value into chunks to comply with devlink's restriction for value length. -The second patch removes redundant code and uses the fixed devlink interface (devlink_fmsg_binary_pair_put). -The third patch make self test to use the updated devlink interface. -The fourth, adds a verification of dumping a very large binary content. This test verifies breaking the data into chunks in a valid JSON output.

Devlink supports pair output of name and value. When the value is binary, it must be presented in an array. If the length of the binary value exceeds fmsg limitation, break the value into chunks internally.
