This patch renames process_hw_error function to handle_hw_ras_error function to match the purpose of the function. This is because hw errors reported through ras and msix interrupts will be handled separately. Signed-off-by:

1.The command interface for queryng and clearing hw errors is changed, which requires the new process error functions to be added. This patch removes all the current process error functions and associated definitions. The new functions to handle ras errors would be added in this patch set. 2. Fixed order issue of the hw_blk table. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Un/offload FDB on NVE detach/attach Petr says: When a VXLAN device is attached to a bridge of a driver capable of offloading such, or upped, the FDB entries already present at the device need to be offloaded. Similarly when an offloaded VXLAN device ceases being interesting (it is downed, or detached, or a front-panel port netdevice is detached from the bridge that the VXLAN device is attached to), any offloaded FDB entries need to be unoffloaded and unmarked. This attach / detach processing is implemented in this patchset. In patch #1, a code pattern is extracted into a named function for easier reuse. In patch #2, vxlan_fdb_replay() is added to send SWITCHDEV_VXLAN_FDB_ADD_TO_DEVICE for each FDB entry with a given VNI. The intention is that the offloading driver will interpret these events like any other and thus offload the FDB entries that existed prior to VXLAN attach. In patches #3 and #4, the functions vxlan_fdb_clear_offload() resp. br_fdb_clear_offload() are added. These clear the offloaded flag at matching FDB entries. In patches #5-#9, we introduce FID-type-specific and NVE-type-specific ops necessary to properly abstract invocations of the replay/clear functions. Finally patch #10 implements the FDB management. In patch #11, the mlxsw-specific test case is extended to check that the management of offload marks under the newly-supported situations is correct. Patch #12, from Ido, exercises the new code paths in actual functional test. v2: - Patch #1: - Modify vxlan_fdb_switchdev_notifier_info() to initialize the structure through a passed-in pointer argument, instead of returning it as a value. - Patch #2: - Adapt to API change in vxlan_fdb_switchdev_notifier_info() ==================== Signed-off-by: -

When using VLAN-aware bridges with VXLAN, the VLAN that is mapped to the VNI of the VXLAN device is that which is configured as "pvid untagged" on the corresponding bridge port. When these flags are toggled or when the VLAN is deleted entirely, remote hosts should not be able to receive packets from the VTEP. Add a test case for above mentioned scenarios. Signed-off-by:

When a VXLAN device is attached to an offloaded bridge, or when a front-panel port is attached to a bridge that already has a VXLAN device, mlxsw should offload the existing offloadable FDB entries. Similarly when VXLAN device is downed, the FDB entries are unoffloaded, and the marks thus need to be cleared. Similarly when a front-panel port device is attached to a bridge with a VXLAN device, or when VLAN flags are tweaked on a VXLAN port attached to a VLAN-aware bridge. Test that the replaying / clearing logic works by observing transitions in presence of offload marks under different scenarios. Signed-off-by:

Any existing NVE FDB entries need to be offloaded when NVE is enabled for a given FID. Recent patches have added fdb_replay op for this, so just invoke it from mlxsw_sp_nve_fid_enable(). When NVE is disabled on a FID, any existing FDB offloaded marks need to be cleared on NVE device as well as on its bridge master. An op to handle this, fdb_clear_offload, has been added to FID ops and NVE ops in previous patches. Add code to resolve the NVE device, NVE type, and dispatch to both fdb_clear_offload ops.

If there are any offloaded FDB entries at bridge master of an NVE device at the time that it's un-offloaded, their offloaded marks need to be cleared. How that is done depends on whether the bridge in question is vlan aware. Therefore add a per-FID-type operation. Implement the operation for the 802.1q and 802.1d bridges. Add and publish a function mlxsw_sp_fid_fdb_clear_offload() to dispatch to the new operation according to FID type. Signed-off-by:

A follow-up patch will add support for replay and for clearing of offload marks. These are NVE type-sensitive operations, and to be able to dispatch them properly, a FID needs to know what NVE type is attached to it. Therefore, track the NVE type at struct mlxsw_sp_fid. Extend mlxsw_sp_fid_vni_set() to take it as an argument, and add mlxsw_sp_fid_nve_type(). Signed-off-by:

Petr Machata says: ==================== Pass extack to NETDEV_PRE_UP Drivers may need to validate configuration of a device that's about to be upped. An example is mlxsw, which needs to check the configuration of a VXLAN device attached to an offloaded bridge. Should the validation fail, there's currently no way to communicate details of the failure to the user, beyond an error number. Therefore this patch set extends the NETDEV_PRE_UP event to include extack, if available. There are three vectors through which NETDEV_PRE_UP invocation can be reached. The two major ones are dev_open() and dev_change_flags(), the last is then __dev_change_flags(). In patch #1, the first access vector, dev_open() is addressed. An extack parameter is added and all users converted to use it. Before addressing the second vector, two preparatory patches propagate extack argument to the proximity of the dev_change_flags() call in VRF and IPVLAN drivers. That happens in patches #2 and #3. Then in patch #4, dev_change_flags() is treated similarly to dev_open(). Likewise in patch #5, __dev_change_flags() is extended. Then in patches #6 and #7, the extack is finally propagated all the way to the point where the notification is emitted. This change allows particularly mlxsw (which already has code to leverage extack if available) to communicate to the user error messages regarding VXLAN configuration. In patch #8, add a test case that exercises this code and checks that an error message is propagated. For example: local 192.0.2.17 remote 192.0.2.18 \ dstport 4789 nolearning noudpcsum tos inherit ttl 100 local 192.0.2.17 remote 192.0.2.18 \ dstport 4789 nolearning noudpcsum tos inherit ttl 100 Error: mlxsw_spectrum: Conflicting NVE tunnels configuration. v2: - Add David Ahern's tags. ==================== Signed-off-by: -

Andrew Lunn says: ==================== Adjust MTU of DSA master interface DSA makes use of additional headers to direct a frame in/out of a specific port of the switch. When the slave interfaces uses an MTU of 1500, the master interface can be asked to handle frames with an MTU of 1504, or 1508 bytes. Some Ethernet interfaces won't transmit/receive frames which are bigger than their MTU. Automate the increasing of the MTU on the master interface, by adding to each tagging driver how much overhead they need, and then calling dev_set_mtu() of the master interface to increase its MTU as needed. ==================== Signed-off-by: -

DSA tagging of frames sent over the master interface to the switch increases the size of the frame. Such frames can then be bigger than the normal MTU of the master interface, and it may drop them. Use the overhead information from the tagger to set the MTU of the master device to include this overhead. Signed-off-by:

Each DSA tag protocol needs to add additional headers to the Ethernet frame in order to direct it towards a specific switch egress port. It must also remove the head from a frame received from a switch. Indicate the maximum size of these headers in the tag protocol ops structure, so the core can take these overheads into account.

When setting LINK tolerance, node timer interval will be calculated base on the LINK with lowest tolerance. But when calculated, the old node timer interval only updated if current setting value (tolerance/4) less than old ones regardless of number of links as well as links' lowest tolerance value. This caused to two cases missing if tolerance changed as following: Case 1: 1.1/ There is one link (L1) available in the system 1.2/ Set L1's tolerance from 1500ms => lower (i.e 500ms) 1.3/ Then, fallback to default (1500ms) or higher (i.e 2000ms) Expected: node timer interval is 1500/4=375ms after 1.3 Result: node timer interval will not being updated after changing tolerance at 1.3 since its value 1500/4=375ms is not less than 500/4=125ms at 1.2. Case 2: 2.1/ There are two links (L1, L2) available in the system 2.2/ L1 and L2 tolerance value are 2000ms as initial 2.3/ Set L2's tolerance from 2000ms => lower 1500ms 2.4/ Disable link L2 (bring down its bearer) Expected: node timer interval is 2000ms/4=500ms after 2.4 Result: node timer interval will not being updated after disabling L2 since its value 2000ms/4=500ms is still not less than 1500/4=375ms at 2.3 although L2 is already not available in the system. To fix this, we start the node interval calculation by initializing it to a value larger than any conceivable calculated value. This way, the link with the lowest tolerance will always determine the calculated value. Acked-by:Jon Maloy <jon.maloy@ericsson.com> Signed-off-by:
