During system shutdown or reboot, mpt3sas will reset the firmware back to ready state. However, the driver leaves running a watchdog work item intended to keep the firmware in operational state. This causes a second, unneeded reset on shutdown and moves the firmware back to operational instead of in ready state as intended. And if the mpt3sas_fwfault_debug module parameter is set, this extra reset also panics the system. mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the firmware back to ready state.

Currently, the data flow of the max/min linkrate in the driver is * in pm8001_get_lrate_mode(): hardcoded value ==> struct sas_phy * in pm8001_bytes_dmaed(): struct pm8001_phy ==> struct sas_phy * in pm8001_phy_control(): libsas data ==> struct pm8001_phy Since pm8001_bytes_dmaed() follows pm8001_get_lrate_mode(), and the fields in struct pm8001_phy are not initialized, sysfs `/sys/class/sas_phy/phy-*/maximum_linkrate` always shows `Unknown`. To fix the issue, change the dataflow to the following: * in pm8001_phy_init(): initial value ==> struct pm8001_phy * in pm8001_get_lrate_mode(): struct pm8001_phy ==> struct sas_phy * in pm8001_phy_control(): libsas data ==> struct pm8001_phy For negotiated linkrate, the current dataflow is: * in pm8001_get_lrate_mode(): iomb data ==> struct asd_sas_phy ==> struct sas_phy * in pm8001_bytes_dmaed(): struct asd_sas_phy ==> struct sas_phy Since pm8001_bytes_dmaed() follows pm8001_get_lrate_mode(), the assignment statements in pm8001_bytes_dmaed() are unnecessary and cleaned up.

The megaraid SCSI driver sets set->nr_maps as 3 if poll_queues is > 0, and blk-mq actually initializes each map's nr_queues as nr_hw_queues.

In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer that gets written out. If this bit is set using commands like "sg_write_same --ndob" we will crash in target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because its NULL. This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal WRITE SAME with no data buffer.

Currently the back pointer from a queue to the vhost adapter isn't set until after subcrq interrupt registration. The value is available when a queue is first allocated and can/should be also set for primary and async queues as well as subcrqs. This fixes a crash observed during kexec/kdump on Power 9 with legacy XICS interrupt controller where a pending subcrq interrupt from the previous kernel can be replayed immediately upon IRQ registration resulting in dereference of a garbage backpointer in ibmvfc_interrupt_scsi().

Currently, the sub-queues and event pool resources are allocated/freed for every CRQ connection event such as reset and LPM. This exposes the driver to a couple issues. First the inefficiency of freeing and reallocating memory that can simply be resued after being sanitized. Further, a system under memory pressue runs the risk of allocation failures that could result in a crippled driver. Finally, there is a race window where command submission/compeletion can try to pull/return elements from/to an event pool that is being deleted or already has been deleted due to the lack of host state around freeing/allocating resources.

Current code is based on the idea that the max number of SGL entries also determines the max size of an I/O request. While this idea was true in older versions of the storvsc driver when SGL entry length was limited to 4 Kbytes, commit 3d9c3dcc ("scsi: storvsc: Enable scatterlist entry lengths > 4Kbytes") removed that limitation. It's now theoretically possible for the block layer to send requests that exceed the maximum size supported by Hyper-V. This problem doesn't currently happen in practice because the block layer defaults to a 512 Kbyte maximum, while Hyper-V in Azure supports 2 Mbyte I/O sizes. But some future configuration of Hyper-V could have a smaller max I/O size, and the block layer could exceed that max. Fix this by correctly setting max_sectors as well as sg_tablesize to reflect the maximum I/O size that Hyper-V reports. While allowing I/O sizes larger than the block layer default of 512 Kbytes doesn’t provide any noticeable performance benefit in the tests we ran, it's still appropriate to report the correct underlying Hyper-V capabilities to the Linux block layer. Also tweak the virt_boundary_mask to reflect that the required alignment derives from Hyper-V communication using a 4 Kbyte page size, and not on the guest page size, which might be bigger (eg. ARM64). Link: https://lore.kernel.org/r/1655190355-28722-1-git-send-email-ssengar@linux.microsoft.com Fixes: 3d9c3dcc ("scsi: storvsc: Enable scatter list entry lengths > 4Kbytes") Reviewed-by:

The kernel returns an endpoint ID as r.ep_connect_ret.handle in the iscsi_uevent. The iscsid validates a received endpoint ID and treats zero as an error. The commit referenced in the fixes line changed the endpoint ID range, and zero is always assigned to the first endpoint ID. So, the first attempt to create a new iSER connection always fails.

When a write command to a sequential write required or sequential write preferred zone result in the zone write pointer reaching the end of the zone, the zone condition must be set to full AND the number of implicitly or explicitly open zones updated to have a correct accounting for zone resources. However, the function zbc_inc_wp() only sets the zone condition to full without updating the open zone counters, resulting in a zone state machine breakage. Introduce the helper function zbc_set_zone_full() and use it in zbc_inc_wp() to correctly transition zones to the full condition.

Nevertheless, gcc complains because the whole Mpi2SasIOUnitPage1_t struct is 32 bytes in size and thus doesn't fit into those 20 bytes. This patch simply allocates all 32 bytes (instead of 20) and thus avoids the warning. There is no functional change introduced by this patch. While touching the code I cleaned up to calculation of max_wideport_qd, max_narrowport_qd and max_sata_qd to make it easier readable.

After issuing a LIP, a specific target vendor does not ACC the FLOGI that lpfc sends. However, it does send its own FLOGI that lpfc ACCs. The target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs and starts the RPI registration for DID 0x000001. The target then sends a LOGO to the fabric DID. lpfc is currently treating the LOGO from the fabric DID as a link down and cleans up all the ndlps. The ndlp for DID 0x000001 is put back into NPR and discovery stops, leaving the port in stuck in bypassed mode. Change lpfc behavior such that if a LOGO is received for the fabric DID in PT2PT topology skip the lpfc_linkdown_port() routine and just move the fabric DID back to NPR.

A use-after-free crash can occur after an ELS LOGO is aborted. Specifically, a nodelist structure is freed and then ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the discovery state machine is mistakenly called a second time with NLP_EVT_DEVICE_RM argument. Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a nodelist structure. Link: https://lore.kernel.org/r/20220603174329.63777-6-jsmart2021@gmail.comCo-developed-by:

Refactoring and consolidation of abort paths: - lpfc_sli4_abort_fcp_cmpl() and lpfc_sli_abort_fcp_cmpl() are combined into a single generic lpfc_sli_abort_fcp_cmpl() routine. Thus, remove extraneous lpfc_sli4_abort_fcp_cmpl() prototype declaration. - lpfc_nvme_abort_fcreq_cmpl() abort completion routine is called with a mismatched argument type. This may result in misleading log message content. Update to the correct argument type of lpfc_iocbq instead of lpfc_wcqe_complete. The lpfc_wcqe_complete should be derived from the lpfc_iocbq structure.

Fixing the interpretation of the length of the B9h VPD page (Concurrent Positioning Ranges). Adding 4 is necessary as the first 4 bytes of the page is the header with page number and length information. Adding 3 was likely a misinterpretation of the SBC-5 specification which sets all offsets starting at zero. This fixes the error in dmesg: [ 9.014456] sd 1:0:0:0: [sda] Invalid Concurrent Positioning Ranges VPD page Link: https://lore.kernel.org/r/20220602225113.10218-4-tyler.erickson@seagate.com Fixes: e815d365 ("scsi: sd: add concurrent positioning ranges support") Cc: stable@vger.kernel.org Tested-by:

The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
