2025-01-02scsi: lpfc: Add handling for LS_RJT reason explanation authentication requiredJustin Tee
When a LS_RJT is received with reason explanation authentication required, current driver logic is to retry the PLOGI up to 48 times. In the worse case scenario, 48 retries can take longer than dev_loss_tmo and if there is an RSCN received indicating an authentication requirement change, the driver may miss processing it. Fix by adding logic to specifically handle reason explanation authentication required and set the max retry count to 8 times.

2025-01-02scsi: lpfc: Modify handling of ADISC based on ndlp state and RPI registrationJustin Tee
In lpfc_check_adisc, remove the requirement that the ndlp object must have been RPI registered. Whether or not the ndlp is RPI registered is unrelated to verifying that the received ADISC is intended for that ndlp rport object. After ADISC receipt, there's no need to put the ndlp state into NPR. Let the cmpl routines from the actions taken earlier in ADISC handling set the proper ndlp state. Also, refactor when a RESUME_RPI mailbox command should be sent. It should only be sent if the RPI registered flag is set.

There's no need to specifically set NLP_EVT_DEVICE_RM when a LOGO completes. The dev_loss_tmo_callbk is responsible for the final kref put.

2025-01-02scsi: bnx2fc: Use kthread_create_on_cpu()Frederic Weisbecker
Use the proper API instead of open coding it. However it looks like bnx2fc_percpu_io_thread() kthread could be replaced by the use of a high prio workqueue instead.

2024-12-23block: remove BLK_MQ_F_SHOULD_MERGEChristoph Hellwig
BLK_MQ_F_SHOULD_MERGE is set for all tag_sets except those that purely process passthrough commands (bsg-lib, ufs tmf, various nvme admin queues) and thus don't even check the flag. Remove it to simplify the driver interface.

2024-12-13scsi/cxlflash: Deprecate driverAndrew Donnellan
We intend to remove the cxlflash driver in an upcoming release. It is already marked as Obsolete in MAINTAINERS. The cxlflash driver has received minimal maintenance for some time, and the CAPI Flash hardware that uses it is no longer commercially available. Add a warning message on probe and change Kconfig to label the driver as deprecated and not build the driver by default.

2024-12-09scsi: storvsc: Don't assume cpu_possible_mask is denseMichael Kelley
Current code allocates the stor_chns array with size num_possible_cpus(). This code assumes cpu_possible_mask is dense, which is not true in the general case per [1]. If cpu_possible_mask is sparse, the array might be indexed by a value beyond the size of the array. However, the configurations that Hyper-V provides to guest VMs on x86 and ARM64 hardware, in combination with how architecture specific code assigns Linux CPU numbers, *does* always produce a dense cpu_possible_mask. So the dense assumption is not currently causing failures. But for robustness against future changes in how cpu_possible_mask is populated, update the code to no longer assume dense. The correct approach is to allocate and initialize the array using size "nr_cpu_ids". While this leaves unused array entries corresponding to holes in cpu_possible_mask, the holes are assumed to be minimal and hence the amount of memory wasted by unused entries is minimal.
