Or Gerlitz says: ==================== net/mlx5_core: Enhance flow steering support v0 --> v1 changes: - fixed improperly formatted comments. - compare value of ib_spec->eth.mask.ether_type in network byte order in ('IB/mlx5: Add flow steering utilities'). v1 --> v2 changes: - made sure that service functions added in the IB driver are only static-fied on the last commit, to make sure bisection with -Werror works fine. v2 --> v3 changes: - squashed patches 11 and 12 into one patch, s.t Dave's comment on unused static functions gcc complaints during bisection is correctly addressed. v3 has been generated against net-next commit c9c99311 "Merge tag 'batman-adv-for-davem' of git://git.open-mesh.org/linux-merge" The series is signed by Matan who was revently assigned to a maintainer for the mlx5_core and IB drivers (this is a 4.5-rc1 change to the maintainers file coming from the rdma tree) -- as such I didn't see a neeed to add my signature (Or). This series adds three new functionalists to the driver flow-steering infrastructure: auto-grouped flow tables, chaining of flow tables and updates for the root flow table. 1. Auto-grouped flow tables - Flow table with auto grouping management. When a flow table is created, hints regarding the number of rule types and the number of rules are given in advance. Thus, a flow table is divided into #NUM_TYPES+1 groups each contains (#NUM_RULES)/(#NUM_TYPES+1) rules. The first #NUM_TYPES parts are groups which are filled if the added rule matches the group specification or the group is empty. The last part is filled by rules that can't fit any of the former groups. 2. Chaining flow tables - Flow tables from different priorities are chained together, if there is no match in flow table of priority i we continue searching for a match in priority i+1. This is both true if priorities i and i+1 belongs to the same namespace or not. 3. Updating the root flow table - the root flow table is the flow table with the lowest level. The hardware start searching for a match in the root flow table and continue according to the matches it find along the way. The first usage for the new functionality is flow steering for user-space ConnectX-4 offloaded HW Eth RX queues done through the mlx5 IB driver. When the mlx5 core driver is loaded, it opens three flow namespaces: 1. By-pass namespace (used by mlx5 IB driver). 2. Kernel namespace (used in order to get packets to the networking stack through mlx5 EN driver). 3. Leftovers namespace (used by mlx5 IB and future sniffer) The series is built as follows: Patch #1 introduces auto-grouped flow tables support. Patch #2 add utility functions for finding the next and the previous flow tables in different priorities. This is used in order to chain the flow tables in a downstream patch. Patch #3 introduces a firmware command for updating the root flow table. Patch #4 introduces modify flow table firmware command, this command is used when we want to change the next flow table of an existing flow table. This is used for chaining flow tables as well. Patch #5 connect/disconnect flow tables. This is actually the chaining process when we want to link flow tables. This means that if we couldn't find a match in the first flow table, we'll continue in the chained flow table. Patch #6 updates priority's attributes that is required for flow table level allocation. We update both the max_fts (the number of allowed FTs in the sub-tree of this priority) and the start_level (which is the first level we'll assign to the flow-tables created inside the priority). Patch #7 adds checking of required device capabilities. Some namespaces could be only created if the hardware supports certain attributes. This is especially true for the Bypass and leftovers namespaces. This adds a generic mechanism to check these required attributes. Patch #8 creates two additional namespaces: a. Bypass flow rules(has nine priorities) b. Leftovers packets(have one priority) - for unmatched packets. Patch #9 re-factors ipv4/ipv6 match fields in the mlx5 firmware interface header to be more clear. Patch #10 exports the flow steering API for mlx5_ib usage Patch #11 implements the required support in mlx5_ib in order to support the RDMA flow steering verbs. ==================== Signed-off-by: NDavid S.

Adding flow steering support by creating a flow-table per priority (if rules exist in the priority). mlx5_ib uses autogrouping and thus only creates the required destinations. Also includes adding of these flow steering utilities 1. Parsing verbs flow attributes hardware steering specs. 2. Check if flow is multicast - this is required in order to decide to which flow table will we add the steering rule. 3. Set outer headers in flow match criteria to zeros.

Add exports to flow steering API for mlx5_ib usage. The following functions are exported: 1. mlx5_create_auto_grouped_flow_table - used to create flow table with auto flow grouping management (create and destroy flow groups). In auto-grouped flow tables, we create groups automatically if needed (if we don't find an existing flow group with same match criteria when we add new rule). 2. mlx5_destroy_flow_table - used to destroy a flow table. 3. mlx5_add_flow_rule - used to add flow rule into a flow table. 4. mlx5_del_flow_rule - used to delete flow rule from its flow table. 5. mlx5_get_flow_namespace - used to get a handle to the required namespace sub-tree.

When the driver is loaded, we create flow steering namespace for kernel bypass with nine priorities and another namespace for leftovers(in order to catch packets that weren't matched). Verbs applications will use these priorities. we found nine as a number that balances the requirements from the user and retains performance. The bypass namespace is used by verbs applications that want to bypass the kernel networking stack. The leftovers namespace is used by verbs applications and the sniffer in order to catch packets that weren't handled by any preceding rules.

Each priority has two attributes: 1. max_ft - maximum allowed flow tables under this priority. 2. start_level - start level range of the flow tables in the priority. These attributes are set by traversing the tree nodes by DFS and set start level and max flow tables to each priority. Start level depends on the max flow tables of the prior priorities in the tree. The leaves of the trees have max_ft set in them. Each node accumulates the max_ft of its children and set it accordingly.

Flow tables from different priorities should be chained together. When a packet arrives we search for a match in the by-pass flow tables (first we search for a match in priority 0 and if we don't find a match we move to the next priority). If we can't find a match in any of the bypass flow-tables, we continue searching in the flow-tables of the next priority, which are the kernel's flow tables. Setting the miss flow table in a new flow table to be the next one in the list is performed via create flow table API. If we want to change an existing flow table, for example in order to point from an existing flow table to the new next-in-list flow table, we use the modify flow table API.

The root Flow Table for each Flow Table Type is defined, by default, as the Flow Table with level 0. In order not to use an empty flow tables and introduce new hops, but still preserve space for flow-tables that have a priority greater(lower number) than the current flow table, we introduce this new set root flow table command. This command tells the HW to start matching packets from the assigned root flow table. This command is used when we create new flow table with level lower than the current lowest flow table or it is the first flow table.

After IPv6 support has recently been added to metadata dst and related encaps, add support for populating/reading it from an eBPF program. Commit d3aa45ce ("bpf: add helpers to access tunnel metadata") started with initial IPv4-only support back then (due to IPv6 metadata support not being available yet). To stay compatible with older programs, we need to test for the passed structure size. Also TOS and TTL support from the ip_tunnel_info key has been added. Tested with vxlan devs in collect meta data mode with IPv4, IPv6 and in compat mode over different network namespaces.

The spew in /proc/net/bonding/bond0 uses netif_carrier_ok() to determine mii_status, while /sys/class/net/bond0/bonding/mii_status looks at curr_active_slave, which doesn't actually seem to be set sometimes when the bond actually is up. A mode 4 bond configured via ifcfg-foo files on a Red Hat Enterprise Linux system, after boot, comes up clean and functional, but the sysfs node shows mii_status of down, while proc shows up. A simple enough fix here seems to be to use the same method for determining up or down in both places, and I'd opt for the one that seems to match reality.
