In commit 9e67600e ("scsi: iscsi: Fix race condition between login and sync thread") we meant to add a check where before we call ->set_param() we make sure the iscsi_cls_connection is bound. The problem is that between versions 4 and 5 of the patch the deletion of the unchecked set_param() call was dropped so we ended up with 2 calls. As a result we can still hit a crash where we access the unbound connection on the first call. This patch removes that first call.

After commit ea2f0f77 ("scsi: core: Cap scsi_host cmd_per_lun at can_queue"), a 416-CPU VM running on Hyper-V hangs during boot because the hv_storvsc driver sets scsi_driver.can_queue to an integer value that exceeds SHRT_MAX, and hence scsi_add_host_with_dma() sets shost->cmd_per_lun to a negative "short" value.

Commit d39df158 ("scsi: iscsi: Have abort handler get ref to conn") added iscsi_get_conn()/iscsi_put_conn() calls during abort handling but then also changed the handling of the case where we detect an already completed task where we now end up doing a goto to the common put/cleanup code. This results in a iscsi_task use after free, because the common cleanup code will do a put on the iscsi_task. This reverts the goto and moves the iscsi_get_conn() to after we've checked if the iscsi_task is valid.

When an FC-GS I/O is aborted by lpfc, the driver requires a node pointer for a dereference operation. In the abort I/O routine, the driver miscasts a context pointer to the wrong data type and overwrites a single byte outside of the allocated space. This miscast is done in the abort I/O function handler because the handler works on both FC-GS and FC-LS commands. However, the code neglected to get the correct job location for the node. Fix this by acquiring the necessary node pointer from the correct job structure depending on the I/O type. Link: https://lore.kernel.org/r/20211004231210.35524-1-jsmart2021@gmail.comCo-developed-by:

The UFS driver uses blk_mq_tagset_busy_iter() when identifying task management requests to complete, however blk_mq_tagset_busy_iter() doesn't work. blk_mq_tagset_busy_iter() only iterates requests dispatched by the block layer. That appears as if it might have started since commit 37f4a24c ("blk-mq: centralise related handling into blk_mq_get_driver_tag") which removed 'data->hctx->tags->rqs[rq->tag] = rq' from blk_mq_rq_ctx_init() which gets called: blk_get_request blk_mq_alloc_request __blk_mq_alloc_request blk_mq_rq_ctx_init Since UFS task management requests are not dispatched by the block layer, hctx->tags->rqs[rq->tag] remains NULL, and since blk_mq_tagset_busy_iter() relies on finding requests using hctx->tags->rqs[rq->tag], UFS task management requests are never found by blk_mq_tagset_busy_iter(). By using blk_mq_tagset_busy_iter(), the UFS driver was relying on internal details of the block layer, which was fragile and subsequently got broken. Fix by removing the use of blk_mq_tagset_busy_iter() and having the driver keep track of task management requests.

Both cxgb4 and csiostor drivers run on their own independent Physical Function. But when cxgb4 and csiostor are both being loaded in parallel via modprobe, there is a race when firmware upgrade is attempted by both the drivers. When the cxgb4 driver initiates the firmware upgrade, it halts the firmware and the chip until upgrade is complete. When the csiostor driver is coming up in parallel, the firmware mailbox communication fails with timeouts and the csiostor driver probe fails. Add a module soft dependency on cxgb4 driver to ensure loading csiostor triggers cxgb4 to load first when available to avoid the firmware upgrade race.

This reverts commit a113eaaf. There are a couple of issues with the commit: 1. It causes deadlocks. 2. It causes the shost->eh_cmd_q list of failed requests not to be processed, ever. So revert it. 1. Deadlocks The SCSI error handler runs with requests blocked beginning when scsi_schedule_eh() sets SHOST_RECOVERY state, continuing through scsi_error_handler() callback ->eh_strategy_handler() until scsi_restart_operations() is called. By setting eh_strategy_handler to ufshcd_err_handler, the patch changed the UFS error handler to run with requests blocked, including PM requests, for the entire run of the error handler. That conflicts with UFS error handler existing synchronization with UFS device PM operations. The UFS error handler synchronizes with runtime PM by doing pm_runtime_get_sync() prior to blocking requests itself. It synchronizes with system PM by use of hba->host_sem, again before blocking requests itself. However, if requests are already blocked, then PM operations will block. So: the UFS error handler blocks waiting on PM + PM blocks waiting on SCSI PM requests to process or fail + PM requests are blocked waiting on error handling to finish = deadlock This happens both for runtime PM and system PM. Prior to the patch, these deadlocks could not happen even if SCSI error handling was running, because the presence of requests in shost->eh_cmd_q would mean the queues could not be suspended, which would mean that, should the UFS error handler run at the same time, it would not need to wait for PM or vice versa. Please note these scenarios are not just theoretical, they were found during testing on a Samsung Galaxy Book S. 2. ->eh_strategy_handler() must process shost->eh_cmd_q list of failed requests, as all other eh_strategy_handler's do except UFS error handler. Refer for example: scsi_unjam_host(), ata_scsi_error() and sas_scsi_recover_host().

ISCSI_NET_PARAM_IFACE_ENABLE belongs to enum iscsi_net_param instead of iscsi_iface_param so move it to ISCSI_NET_PARAM. Otherwise, when we call into the driver, we might not match and return that we don't want attr visible in sysfs. Found in code review.
