2021-06-02scsi: qedi: Fix race during abort timeoutsMike Christie
If the SCSI cmd completes after qedi_tmf_work calls iscsi_itt_to_task then the qedi qedi_cmd->task_id could be freed and used for another cmd. If we then call qedi_iscsi_cleanup_task with that task_id we will be cleaning up the wrong cmd. Wait to release the task_id until the last put has been done on the iscsi_task. Because libiscsi grabs a ref to the task when sending the abort, we know that for the non-abort timeout case that the task_id we are referencing is for the cmd that was supposed to be aborted. A latter commit will fix the case where the abort times out while we are running qedi_tmf_work.

2021-06-02scsi: qedi: Fix null ref during abort handlingMike Christie
If qedi_process_cmd_cleanup_resp finds the cmd it frees the work and sets list_tmf_work to NULL, so qedi_tmf_work should check if list_tmf_work is non-NULL when it wants to force cleanup.

2021-06-02scsi: iscsi: Fix shost->max_id useMike Christie
The iscsi offload drivers are setting the shost->max_id to the max number of sessions they support. The problem is that max_id is not the max number of targets but the highest identifier the targets can have. To use it to limit the number of targets we need to set it to max sessions - 1, or we can end up with a session we might not have preallocated resources for.

2021-06-02scsi: iscsi: Stop queueing during ep_disconnectMike Christie
During ep_disconnect we have been doing iscsi_suspend_tx/queue to block new I/O but every driver except cxgbi and iscsi_tcp can still get I/O from __iscsi_conn_send_pdu() if we haven't called iscsi_conn_failure() before ep_disconnect. This could happen if we were terminating the session, and the logout timed out before it was even sent to libiscsi. Fix the issue by adding a helper which reverses the bind_conn call that allows new I/O to be queued. Drivers implementing ep_disconnect can use this to make sure new I/O is not queued to them when handling the disconnect.

The new route handling in ip_mc_finish_output() from 'net' overlapped with the new support for returning congestion notifications from BPF programs. In order to handle this I had to take the dev_loopback_xmit() calls out of the switch statement. The aquantia driver conflicts were simple overlapping changes. Signed-off-by: David S.
