Add BR_HAIRPIN_MODE, BR_ISOLATED and BR_MULTICAST_TO_UNICAST port flags to BR_PORT_FLAGS_HW_OFFLOAD so that switchdev drivers which have an offloaded data plane have a chance to reject these bridge port flags if they don't support them yet. It makes the code path go through the SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS driver handlers, which return -EINVAL for everything they don't recognize. For drivers that don't catch SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS at all, switchdev will return -EOPNOTSUPP for those which is then ignored, but those are in the minority.

2022-04-11net: lan966x: Add FDMA functionalityHoratiu Vultur5-4/+851
Ethernet frames can be extracted or injected to or from the device's DDR memory. There is one channel for injection and one channel for extraction. Each of these channels contain a linked list of DCBs which contains DB. The DCB contains only 1 DB for both the injection and extraction. Each DB contains a frame. Every time when a frame is received or transmitted an interrupt is generated. It is not possible to use both the FDMA and the manual injection/extraction of the frames. Therefore the FDMA has priority over the manual because of better performance values.

On lan966x it is not allowed to have foreign interfaces under a bridge which already contains lan966x ports. So when a port leaves the bridge it would call switchdev_bridge_port_unoffload which eventually will notify the other ports that bridge left the vlan group but that is not true because the bridge is still part of the vlan group. Therefore when a port leaves the bridge, stop generating replays because already the HW cleared after itself and the other ports don't need to do anything else.

The issue is that the default value is wrong, meaning that in case the DUT was a grandmaster then everone in the network was too slow.

We set the qedi_ep state to EP_STATE_OFLDCONN_START when the ep is created. Then in qedi_set_path we kick off the offload work. If userspace times out the connection and calls ep_disconnect, qedi will only flush the offload work if the qedi_ep state has transitioned away from EP_STATE_OFLDCONN_START. If we can't connect we will not have transitioned state and will leave the offload work running, and we will free the qedi_ep from under it. This patch just has us init the work when we create the ep, then always flush it.

2022-04-11scsi: iscsi: Fix unbound endpoint error handlingMike Christie1-29/+36
If a driver raises a connection error before the connection is bound, we can leave a cleanup_work queued that can later run and disconnect/stop a connection that is logged in. The problem is that drivers can call iscsi_conn_error_event for endpoints that are connected but not yet bound when something like the network port they are using is brought down. iscsi_cleanup_conn_work_fn will check for this and exit early, but if the cleanup_work is stuck behind other works, it might not get run until after userspace has done ep_disconnect. Because the endpoint is not yet bound there was no way for ep_disconnect to flush the work. The bug of leaving stop_conns queued was added in: Commit 23d6fefbb3f6 ("scsi: iscsi: Fix in-kernel conn failure handling") and: Commit 0ab710458da1 ("scsi: iscsi: Perform connection failure entirely in kernel space") was supposed to fix it, but left this case. This patch moves the conn state check to before we even queue the work so we can avoid queueing.

2022-04-11scsi: iscsi: Fix conn cleanup and stop race during iscsid restartMike Christie2-0/+19
If iscsid is doing a stop_conn at the same time the kernel is starting error recovery we can hit a race that allows the cleanup work to run on a valid connection. In the race, iscsi_if_stop_conn sees the cleanup bit set, but it calls flush_work on the clean_work before iscsi_conn_error_event has queued it. The flush then returns before the queueing and so the cleanup_work can run later and disconnect/stop a conn while it's in a connected state. The patch: Commit 0ab710458da1 ("scsi: iscsi: Perform connection failure entirely in kernel space") added the late stop_conn call bug originally, and the patch: Commit 23d6fefbb3f6 ("scsi: iscsi: Fix in-kernel conn failure handling") attempted to fix it but only fixed the normal EH case and left the above race for the iscsid restart case. For the normal EH case we don't hit the race because we only signal userspace to start recovery after we have done the queueing, so the flush will always catch the queued work or see it completed. For iscsid restart cases like boot, we can hit the race because iscsid will call down to the kernel before the kernel has signaled any error, so both code paths can be running at the same time. This adds a lock around the setting of the cleanup bit and queueing so they happen together.

2022-04-11scsi: iscsi: Fix endpoint reuse regressionMike Christie1-1/+11
This patch fixes a bug where when using iSCSI offload we can free an endpoint while userspace still thinks it's active. That then causes the endpoint ID to be reused for a new connection's endpoint while userspace still thinks the ID is for the original connection. Userspace will then end up disconnecting a running connection's endpoint or trying to bind to another connection's endpoint. This bug is a regression added in: Commit 23d6fefbb3f6 ("scsi: iscsi: Fix in-kernel conn failure handling") where we added a in kernel ep_disconnect call to fix a bug in: Commit 0ab710458da1 ("scsi: iscsi: Perform connection failure entirely in kernel space") where we would call stop_conn without having done ep_disconnect. This early ep_disconnect call will then free the endpoint and it's ID while userspace still thinks the ID is valid. Fix the early release of the ID by having the in kernel recovery code keep a reference to the endpoint until userspace has called into the kernel to finish cleaning up the endpoint/connection. It requires the previous commit "scsi: iscsi: Release endpoint ID when its freed" which moved the freeing of the ID until when the endpoint is released.

2022-04-11scsi: iscsi: Release endpoint ID when its freedMike Christie2-37/+36
We can't release the endpoint ID until all references to the endpoint have been dropped or it could be allocated while in use. This has us use an idr instead of looping over all conns to find a free ID and then free the ID when all references have been dropped instead of when the device is only deleted.

2022-04-11scsi: iscsi: Fix offload conn cleanup when iscsid restartsMike Christie1-20/+28
When userspace restarts during boot or upgrades it won't know about the offload driver's endpoint and connection mappings. iscsid will start by cleaning up the old session by doing a stop_conn call. Later, if we are able to create a new connection, we clean up the old endpoint during the binding stage. The problem is that if we do stop_conn before doing the ep_disconnect call offload, drivers can still be executing I/O. We then might free tasks from the under the card/driver. This moves the ep_disconnect call to before we do the stop_conn call for this case. It will then work and look like a normal recovery/cleanup procedure from the driver's point of view.

When upper inbound and outbound queues 32-63 are enabled, we see upper vectors 32-63 in interrupt service routine. We need corresponding registers to handle masking and unmasking of these upper interrupts. To achieve this, we use registers MSGU_ODMR_U(0x34) to mask and MSGU_ODMR_CLR_U(0x3C) to unmask the interrupts. In these registers bit 0-31 represents interrupt vectors 32-63.
