2016-01-11bonding: Prevent IPv6 link local address on enslaved devicesKarl Heiss
Commit 1f718f0f4f97 ("bonding: populate neighbour's private on enslave") undoes the fix provided by commit c2edacf80e15 ("bonding / ipv6: no addrconf for slaves separately from master") by effectively setting the slave flag after the slave has been opened. If the slave comes up quickly enough, it will go through the IPv6 addrconf before the slave flag has been set and will get a link local IPv6 address. In order to ensure that addrconf knows to ignore the slave devices on state change, set IFF_SLAVE before dev_open() during bonding enslavement.

2016-01-11IB/mlx5: Add flow steering supportMaor Gottlieb
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.

2016-01-11net/mlx5_core: Enable flow steering support for the IB driverMaor Gottlieb
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.

2016-01-11net/mlx5_core: Set priority attributesMaor Gottlieb
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.

2016-01-11net/mlx5_core: Connect flow tablesMaor Gottlieb
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.

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.

2016-01-11bonding: make mii_status sysfs node consistentJarod Wilson
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.

2016-01-11mlxsw: spectrum: Add FDB lock to prevent session interleavingIdo Schimmel
Dumping the FDB (invoked with a process context) or handling FDB notifications (polled periodicly in delayed work) might each entail multiple EMAD transcations due to the number of entries. While we only allow one EMAD transaction at a time, there is nothing stopping the dump and notification processing sessions from interleaving. However, this is forbidden by the hardware, so we need to make sure only one of these sessions can run at a time. Solve this by adding a mutex ('fdb_lock'), as both kernel threads can sleep while waiting for the response EMAD.

2016-01-10udp: restrict offloads to one namespaceHannes Frederic Sowa
udp tunnel offloads tend to aggregate datagrams based on inner headers. gro engine gets notified by tunnel implementations about possible offloads. The match is solely based on the port number. Imagine a tunnel bound to port 53, the offloading will look into all DNS packets and tries to aggregate them based on the inner data found within. This could lead to data corruption and malformed DNS packets. While this patch minimizes the problem and helps an administrator to find the issue by querying ip tunnel/fou, a better way would be to match on the specific destination ip address so if a user space socket is bound to the same address it will conflict.

2016-01-10mlxsw: Adding layer 2 multicast supportElad Raz
Add SWITCHDEV_OBJ_ID_PORT_MDB switchdev ops support. On first MDB insertion creates a new multicast group (MID) and add members port to the MID. Also add new MDB entry for the flooding-domain (fid-vid) and link the MDB entry to the newly constructed MC group.
