Upon receiving notification from firmware the CGX event handler in the AF driver gets the current link info such as status, speed, duplex etc from CGX driver and sends it across to PFs who have registered to receive such notifications. To support above - Mbox messaging support for sending msgs from AF to PF has been added. - Added mbox msgs so that PFs can register/unregister for link events. - Link notifications are sent to PF under two scenarioss. 1. When a asynchronous link change notification is received from firmware with notification flag turned on for that PF. 2. Upon notification turn on request, the current link status is send to the PF. Also added a new mailbox msg using which RVU PF/VF can retrieve their mapped CGX LMAC's current link info. Link info includes status, speed, duplex and lmac type. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add VxLAN support This patchset adds support for VxLAN offload in the mlxsw driver. With regards to the forwarding plane, VxLAN support is composed from two main parts: Encapsulation and decapsulation. In the device, NVE encapsulation (and VxLAN in particular) takes place in the bridge. A packet can be encapsulated using VxLAN either because it hit an FDB entry that forwards it to the router with the IP of the remote VTEP or because it was flooded, in which case it is sent to a list of remote VTEPs (in addition to local ports). In either case, the VNI is derived from the filtering identifier (FID) the packet was classified to at ingress and the underlay source IP is taken from a device global configuration. VxLAN decapsulation takes place in the underlay router, where packets that hit a local route that corresponds to the source IP of the local VTEP are decapsulated and injected to the bridge. The packets are classified to a FID based on the VNI they came with. The first six patches export the required APIs in the VxLAN and mlxsw drivers in order to allow for the introduction of the NVE core in the next two patches. The NVE core is designed to support a variety of NVE encapsulations (e.g., VxLAN, NVGRE) and different ASICs, but currently only VxLAN and Spectrum are supported. Spectrum-2 support will be added in the future. The last 10 patches add support for VxLAN decapsulation and encapsulation and include the addition of the required switchdev APIs in the VxLAN driver. These APIs allow capable drivers to get a notification about the addition / deletion of FDB entries to / from the VxLAN's FDB. Subsequent patchset will add selftests (generic and mlxsw-specific), data plane learning, FDB extack and vetoing and support for VLAN-aware bridges (one VNI per VxLAN device model). v2: * Implement netif_is_vxlan() using rtnl_link_ops->kind (Jakub & Stephen) ==================== Signed-off-by:

In the device, VxLAN encapsulation takes place in the FDB table where certain {MAC, FID} entries are programmed with an underlay unicast IP. MAC addresses that are not programmed in the FDB are flooded to the relevant local ports and also to a list of underlay unicast IPs that are programmed using the all zeros MAC address in the VxLAN driver. One difference between the hardware and software data paths is the fact that in the software data path there are two FDB lookups prior to the encapsulation of the packet. First in the bridge's FDB table using {MAC, VID} and another in the VxLAN's FDB table using {MAC, VNI}. Therefore, when a new VxLAN FDB entry is notified, it is only programmed to the device if there is a corresponding entry in the bridge's FDB table. Similarly, when a new bridge FDB entry pointing to the VxLAN device is notified, it is only programmed to the device if there is a corresponding entry in the VxLAN's FDB table. Note that the above scheme will result in a discrepancy between both data paths if only one FDB table is populated in the software data path. For example, if only the bridge's FDB is populated with an entry pointing to a VxLAN device, then a packet hitting the entry will only be flooded by the kernel to remote VTEPs whereas the device will also flood the packets to other local ports member in the VLAN.

Enslavement of VxLAN devices to offloaded bridges was never forbidden by mlxsw, but this patch makes sure the required configuration is performed in order to allow VxLAN encapsulation and decapsulation to take place in the device. The patch handles both the case where a VxLAN device is enslaved to an already offloaded bridge and the case where the first mlxsw port is enslaved to a bridge that already has VxLAN device configured. Invalid configurations are sanitized and an error string is returned via extack. Since encapsulation and decapsulation do not occur when the VxLAN device is down, the driver makes sure to enable / disable these functionalities based on NETDEV_PRE_UP and NETDEV_DOWN events. Note that NETDEV_PRE_UP is used in favor of NETDEV_UP, as the former allows to veto the operation, if necessary. Signed-off-by:

Currently, an FDB entry only ceases being offloaded when it is deleted. This changes with VxLAN encapsulation. Devices capable of performing VxLAN encapsulation usually have only one FDB table, unlike the software data path which has two - one in the bridge driver and another in the VxLAN driver. Therefore, bridge FDB entries pointing to a VxLAN device are only offloaded if there is a corresponding entry in the VxLAN FDB. Allow clearing the offload indication in case the corresponding entry was deleted from the VxLAN FDB. Signed-off-by:

To that end, introduce a new event, SWITCHDEV_VXLAN_FDB_OFFLOADED, through which the marking is communicated to the vxlan driver. To identify which RDST should be marked as offloaded, an switchdev_notifier_vxlan_fdb_info is passed to the listeners. The "offloaded" flag in that object determines whether the offloaded mark should be set or cleared. When sending offloaded FDB entries over netlink, mark them with NTF_OFFLOADED. Signed-off-by:

Drivers that support tunnel decapsulation (IPinIP or NVE) need to configure the underlying device to conform to the behavior outlined in RFC 6040 with respect to the ECN bits. This behavior is implemented by INET_ECN_decapsulate() which requires an skb to be passed where the ECN CE bit can be potentially set. Since these drivers do not need to mark an skb, but only configure the device to do so, factor out the business logic to __INET_ECN_decapsulate() and potentially perform the marking in INET_ECN_decapsulate(). This allows drivers to invoke __INET_ECN_decapsulate() and configure the device. Signed-off-by:

In the device, the VNI and the list of remote VTEPs a packet should be flooded to is a property of the filtering identifier (FID). During encapsulation, the VNI is taken from the FID the packet was classified to. During decapsulation, the overlay packet is injected into a bridge and classified to a FID based on the VNI it came with. Allow NVE configuration for a FID. Currently, this is only supported with 802.1D FIDs which are used for VLAN-unaware bridges. However, NVE configuration is going to be supported with 802.1Q FIDs which is why the related fields are placed in the common FID struct. Since the device requires a 1:1 mapping between FID and VNI, the driver maintains a hashtable keyed by VNI and checks if the VNI is already associated with an existing FID. Signed-off-by:

Eric reported that syzkaller triggered a splat in tcp_cleanup_ulp() where assertion sock_owned_by_me() failed. This happened through inet_csk_prepare_forced_close() first releasing the socket lock, then calling into tcp_done(newsk) which is called after the inet_csk_prepare_forced_close() and therefore without the socket lock held. The sock_owned_by_me() assertion can generally be removed as the only place where tcp_cleanup_ulp() is called from now is out of inet_csk_destroy_sock() -> sk->sk_prot->destroy() where socket is in dead state and unreachable. Therefore, add a comment why the check is not needed instead. Fixes: 8b9088f8 ("tcp, ulp: enforce sock_owned_by_me upon ulp init and cleanup") Reported-by:

There is a pool of PTT maintained, and several PTT are used simultaneously to access device registers in different flows. Same PTT should not be used in flows that can run concurrently. To avoid running out of PTT resources, too many PTT should not be acquired without releasing them. Every PF has a global PTT, which is used throughout the life of PF, in most important flows for register access. Generic functions acquire the PTT locally and release after the use.
