2020-08-17Revert "scsi: qla2xxx: Disable T10-DIF feature with FC-NVMe during probe"Quinn Tran
FCP T10-PI and NVMe features are independent of each other. This patch allows both features to co-exist. This reverts commit 5da05a26b8305a625bc9d537671b981795b46dab.

2020-08-17scsi: scsi_debug: Fix scp is NULL errorsDouglas Gilbert
John Garry reported 'sdebug_q_cmd_complete: scp is NULL' failures that were mainly seen on aarch64 machines (e.g. RPi 4 with four A72 CPUs). The problem was tracked down to a missing critical section on a "short circuit" path. Namely, the time to process the current command so far has already exceeded the requested command duration (i.e. the number of nanoseconds in the ndelay parameter). The random=1 parameter setting was pivotal in finding this error. The failure scenario involved first taking that "short circuit" path (due to a very short command duration) and then taking the more likely hrtimer_start() path (due to a longer command duration). With random=1 each command's duration is taken from the uniformly distributed [0..ndelay) interval. The fio utility also helped by reliably generating the error scenario at about once per minute on a RPi 4 (64 bit OS).

If the bit corresponding to a task in the Doorbell register has been cleared, no need to poll the status of the task on the device side and to send an Abort Task TM. Instead, let it directly goto cleanup. In addition, to keep original debug output, move the goto below the debug print.

2020-08-17scsi: ufs: Clean up completed request without interrupt notificationStanley Chu
If somehow no interrupt notification is raised for a completed request and its doorbell bit is cleared by host, UFS driver needs to cleanup its outstanding bit in ufshcd_abort(). Otherwise, system may behave abnormally in the following scenario: After ufshcd_abort() returns, this request will be requeued by SCSI layer with its outstanding bit set. Any future completed request will trigger ufshcd_transfer_req_compl() to handle all "completed outstanding bits". At this time the "abnormal outstanding bit" will be detected and the "requeued request" will be chosen to execute request post-processing flow. This is wrong because this request is still "alive".

2020-08-17scsi: ufs: Fix possible infinite loop in ufshcd_holdStanley Chu
In ufshcd_suspend(), after clk-gating is suspended and link is set as Hibern8 state, ufshcd_hold() is still possibly invoked before ufshcd_suspend() returns. For example, MediaTek's suspend vops may issue UIC commands which would call ufshcd_hold() during the command issuing flow. Now if UFSHCD_CAP_HIBERN8_WITH_CLK_GATING capability is enabled, then ufshcd_hold() may enter infinite loops because there is no clk-ungating work scheduled or pending. In this case, ufshcd_hold() shall just bypass, and keep the link as Hibern8 state.

2020-08-04scsi: lpfc: Fix LUN loss after cable pullDick Kennedy
On devices that support FCP sequence error recovery, which attempts to preserve the devices login across link bounce, adisc is used for device validation. Turns out the device fc4 type is cleared as part of the link bounce, but the ADISC handling doesn't restore the FC4 support as it normally would with a PRLI. This caused situations where the device wasn't reregistered with the transport thus scan logic and LUN discovery never kicked in. In the ADISC completion handling, reset the fc4 type so that transport port reregistration occurs with the remote port.

2020-08-04scsi: lpfc: Fix retry of PRLI when status indicates its unsupportedDick Kennedy
With port bounce/address swaps and timing between initiator GID queries vs remote port FC4 support registrations, the driver may be in a situation where it sends PRLIs for both FCP and NVME even though the target may not support one of the protocols. In this case, the remote port will reject the PRLI and usually indicate it does not support the request. However, the driver currently ignores the status of the failure and immediately retries the PRLI, which is pointless. In the case of this one remote port, the reception of the PRLI retry caused it to decide to send a LOGO. The LOGO restarted the process and the same results happened. It made the remote port undiscoverable to either protocol. Add logic to detect the non-support status and not attempt the retry of the PRLI.

2020-08-04scsi: lpfc: Fix RSCN timeout due to incorrect gidft counterDick Kennedy
In configs with a large number of initiators in the same zone (>250), RSCN timeouts are seen when creating or deleting vports: lpfc 0000:07:00.1: 5:(0):0231 RSCN timeout Data: x0 x3 During RSCN processing driver issues GID_FT command to nameserver. A counter for number of simultaneous GID_FT commands is maintained (an unsigned value). The counter is incremented when the GID_FT is issued. If the GID_FT command fails for some reason the driver retries the GID_FT from the completion call back. But the counter was decremented before the retry was issued. When the second GID_FT completes, the callback again tries to decrement the counter, possibly wrapping to a very large non-zero value, which causes the RSCN cleanup code to not execute. Thus the RSCN timeout failure. Do not decrement the counter on a retry. Also add defensive checks to ensure the counter is not decremented if already zero.

2020-08-04scsi: lpfc: nvmet: Avoid hang / use-after-free again when destroying targetportEwan D. Milne
We cannot wait on a completion object in the lpfc_nvme_targetport structure in the _destroy_targetport() code path because the NVMe/fc transport will free that structure immediately after the .targetport_delete() callback. This results in a use-after-free, and a crash if slub_debug=FZPU is enabled. An earlier fix put put the completion on the stack, but commit 2a0fb340fcc8 ("scsi: lpfc: Correct localport timeout duration error") subsequently changed the code to reference the completion through a pointer in the object rather than the local stack variable. Fix this by using the stack variable directly.

2020-08-04scsi: sd_zbc: Improve zone revalidationDamien Le Moal
Currently, for zoned disks, since blk_revalidate_disk_zones() requires the disk capacity to be set already to operate correctly, zones revalidation can only be done on the second revalidate scan once the gendisk capacity is set at the end of the first scan. As a result, if zone revalidation fails, there is no second chance to recover from the failure and the disk capacity is changed to 0, with the disk left unusable. This can be improved by shuffling around code, specifically, by moving the call to sd_zbc_revalidate_zones() from sd_zbc_read_zones() to the end of sd_revalidate_disk(), after set_capacity_revalidate_and_notify() is called to set the gendisk capacity. With this change, if sd_zbc_revalidate_zones() fails on the first scan, the second scan will call it again to recover, if possible. Using the new struct scsi_disk fields rev_nr_zones and rev_zone_blocks, sd_zbc_revalidate_zones() does actual work only if it detects a change with the disk zone configuration. This means that for a successful zones revalidation on the first scan, the second scan will not cause another heavy full check. While at it, remove the unecesary "extern" declaration of sd_zbc_read_zones().

2020-08-04scsi: fcoe: Memory leak fix in fcoe_sysfs_fcf_del()Javed Hasan
In fcoe_sysfs_fcf_del(), we first deleted the fcf from the list and then freed it if ctlr_dev was not NULL. This was causing a memory leak. Free the fcf even if ctlr_dev is NULL.

2020-07-30scsi: scsi_transport_srp: Sanitize scsi_target_block/unblock sequencesHannes Reinecke
The SCSI midlayer does not allow state transitions from SDEV_BLOCK to SDEV_BLOCK so calling scsi_target_block() from __rport_fast_io_fail() is wrong as the port is already blocked. Similarly, we don't need to call scsi_target_unblock() afterwards as the function has already done this.
