Due to a typo we would always be using the MIB counter width of the first element of the counter array instead of the current element, and we would always be accessing the register statistics with a 64-bits read, while some could be 32-bits. This got unnoticed in testing with MDIO and SRAB which tolerate doing this, but testing with the SPI bus revealed bogus values being returned. Fix this by using the proper iterator here.

The commit f2a4d086 ("openvswitch: Add packet truncation support.") introduces packet truncation before sending to userspace upcall receiver. This patch passes up the skb->len before truncation so that the upcall receiver knows the original packet size. Potentially this will be used by sFlow, where OVS translates sFlow config header=N to a sample action, truncating packet to N byte in kernel datapath. Thus, only N bytes instead of full-packet size is copied from kernel to userspace, saving the kernel-to-userspace bandwidth. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Preparation for IPv4 router Ido says: This series prepares the driver for IPv4 router support. The router follow-up patches are available at: https://github.com/jpirko/linux_mlxsw/tree/net-next_queue Patches 1-9 simplify the netdevice notification block and also add several checks during PRECHANGEUPPER events against topologies that aren't supported by the device. This will ensure L3 interfaces are only configured on top of valid netdevs. Patches 10-13 contain trivial changes required for the introduction of a generic FID struct - currently only used for vFIDs - in patch 14. Making the FID struct generic will allow us to easily associate the underlying FIDs with their L3-counterparts - Router interfaces (RIFs): FID Type | Used by | RIF Type -------------------------------------------------------- FID | The VLAN-aware bridge | VLAN vFID | VLAN-unaware bridges | FID rFID | non-bridged netdevs (follow-up) | Sub-port Obligatory ASCII art to visualize the above: A.B.C.D + | FID RIF + br0 E.F.G.H + + | | VLAN RIF +---------+---------+ + | | br1.W | vFID | + | | | vPort +-+-+ +-+-+ + swXpY.Z | | | | br1 +-+-+ +-+-+ + | | FID=W | | | +------------+------------+ | | | | +---+---+ +---+-+-+ +---+---+ | | | | | | | | | | | | | | | | | | +-------+ +-------+ +-------+ swXpY Patches 15-16 further generalize the struct by exploiting the fact that the FID is a shared resource among ports. Each FID type is assigned a 'leave' function that is invoked based on CHANGEUPPER events and takes care of the necessary clean-up. Patches 17-22 build upon the previous patches and use the FID struct for the VLAN-aware bridge and take care of cleaning up FID resources in the 'leave' functions. For now, these are only FDB records, but later on we'll have to remove the RIFs associated with these FIDs, which will in turn take care of routes and neighbours clean-up. The last patch adds debug prints that proved very useful during the development of this series.

There are situations in which a vPort is destroyed while still holding references to device's resources such as FIDs and FDB records. This can happen, for example, when a VLAN device is deleted while still being bridged. Instead of trying to make sure vPort destruction is invoked when it no longer uses device's resources, just free them upon destruction. This simplifies the code, as we no longer need to take different situations into account when events are received - cleanup is taken care of in one place. Signed-off-by:

FDB entries are learned using {Port / LAG ID, FID} and therefore should be flushed whenever a port (vPort) leaves its FID (vFID). However, when the bridge port is a LAG device (or a VLAN device on top), then FDB flushing is conditional. Ports removed from such LAG configurations must not trigger flushing, as other ports might still be members in the LAG and therefore the bridge port is still active. The decision whether to flush or not was previously computed in the netdevice notification block, but in order to flush the entries when a port leaves its FID this decision should be computed there. Strip the notification block from this logic and instead move it to one FDB flushing function that is invoked from both the FID / vFID leave functions. When port isn't member in LAG, FDB flushing should always occur. Otherwise, it should occur only when the last port (vPort) member in the LAG leaves the FID (vFID). This will allow us - in the next patch - to simplify the cleanup code paths that are hit whenever the topology above the port netdevs changes. Signed-off-by: -

As previously explained, not all vPorts will be assigned FIDs, so instead of returning the FID index of a vPort, return a pointer to its FID struct. This will allow us to know whether it's legal to access the vPort's FID parameters such as index and device. Signed-off-by:

When L3 interfaces will be introduced a vPort won't necessarily have a FID assigned to it. This can happen if it's not member in a bridge (in which case it's assigned a vFID) or doesn't have an IP address (in which case it's assigned an rFID). Therefore, instead check the VID parameter to test whether a port is a vPort or not. Signed-off-by:

In a very similar way to the vFIDs, make the first 4K FIDs - used in the VLAN-aware bridge - use the new FID struct. Upon first use of the FID by any of the ports do the following: 1) Create the FID 2) Setup a matching flooding entry 3) Create a mapping for the FID Unlike vFIDs, upon creation of a FID we always create a global VID-to-FID mapping, so that ports without upper vPorts can use it instead of creating an explicit {Port, VID} to FID mapping. When a port leaves a FID the reverse is performed. Whenever the FID's reference count reaches zero the FID is deleted along with the global mapping. The per-FID struct will later allow us to configure L3 interfaces on top of the VLAN-aware bridge. Signed-off-by: -

When a vPort is created or when it joins a bridge we always do the same set of operations: 1) Create the vFID, if not already created 2) Setup flooding for the vFID 3) Map the {Port, VID} to the vFID When a vPort is destroyed or when it leaves a bridge the reverse is performed. Encapsulate the above in join / leave functions and simplify the code. FIDs and rFIDs will use a similar set of functions. Signed-off-by: -

Up until now we had a dedicated struct only for vFIDs, but before introducing support for L3 interfaces we need to make it generic and use it for all three types of FIDs: 1) FIDs - 0..4K-1, used for the VLAN-aware bridge 2) vFIDs - 4K..15K-1, used for VLAN-unaware bridges 3) rFIDs - 15K..16K-1, used to direct traffic to / from the router in the device. Will be introduced later in the series. The three types of L3 interfaces - Router InterFaces, RIFs - that will be introduced correspond to the three types of FIDs and are configured using them. Therefore, we'll need to store the links between them as well as a reference count on the underlying FID, so that the corresponding RIF will be destroyed when it reaches zero. Note that the lower 0.5K vFIDs are currently used for for non-bridged netdevs, so that traffic could be flooded to the CPU port. However, when rFIDs will be introduced we'll no longer need these and they too will be used for VLAN-unaware bridges. Make the vFID struct generic by renaming it and some of its fields. FIDs will be converted to use it later in the series. Signed-off-by:

A FID used by a vPort (vFID, but also rFID later in the series) is always mapped using {Port, VID} and not only VID as with the 4K FIDs of the VLAN-aware bridge. Instead of specifying all the arguments each time, just wrap this operation using a dedicated function and simplify the code. As before, the function takes FID as its argument in preparation for a generic FID struct. Signed-off-by: -

Simplify the code and use only one function for vFID creation / destruction. Unlike before, the function receives a FID index as its argument and not a vFID index. Instead of passing 0, now one would need to pass 4K, which is the first vFID. This is the first step in creating a generic FID struct that will be used for all three types of FIDs. Signed-off-by:

When responding to unlinking CHANGEUPPER notifications we shouldn't return any value, as it's not checked by upper layers.
