In sas_notify_lldd_dev_found(), if we can't allocate the necessary resources, then it seems like the wrong thing to mark the device as found and to increment the reference count. None of the callers ever drop the reference in that situation.

2020-09-02scsi: libsas: Set data_dir as DMA_NONE if libata marks qc as NODATALuo Jiaxing1-1/+4
It was discovered that sdparm will fail when attempting to disable write cache on a SATA disk connected via libsas. In the ATA command set the write cache state is controlled through the SET FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and the latter command is what is used in the SCSI-ATA translation layer. A subtle difference is that a MODE SELECT carries data whereas SET FEATURES is defined as a non-data command in ATA. Set the DMA data direction to DMA_NONE if the requested ATA command is identified as non-data.

2020-09-01scsi: lpfc: Fix FLOGI/PLOGI receive race condition in pt2pt discoveryJames Smart1-1/+3
The driver is unable to successfully login with remote device. During pt2pt login, the driver completes its FLOGI request with the remote device having WWN precedence. The remote device issues its own (delayed) FLOGI after accepting the driver's and, upon transmitting the FLOGI, immediately recognizes it has already processed the driver's FLOGI thus it transitions to sending a PLOGI before waiting for an ACC to its FLOGI. In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI being received and an ACC sent. The issue is that the PLOGI reception occurs before the response from the adapter from the FLOGI ACC is received. Processing of the PLOGI sets state flags to perform the REG_RPI mailbox command and proceed with the rest of discovery on the port. The same completion routine used by both FLOGI and PLOGI is generic in nature. One of the things it does is clear flags, and those flags happen to drive the rest of discovery. So what happened was the PLOGI processing set the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC completes it doesn't see the flags and stops. Fix by modifying the generic completion routine to not clear the rest of discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated with performing a mailbox command as part of its handling. For things such as FLOGI ACC, there isn't a subsequent action to perform with the adapter, thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI upon completion, thus there is a mailbox cmd ptr.

2020-08-25scsi: scsi_debug: Remove superfluous close zone in resp_open_zone()Niklas Cassel1-2/+0
resp_open_zone() always calls zbc_open_zone() with parameter explicit set to true. If zbc_open_zone() is called with parameter explicit set to true, and the current zone state is implicit open, it will call zbc_close_zone() on the zone before proceeding. Therefore, there is no need for resp_open_zone() to call zbc_close_zone() on an implicitly open zone before calling zbc_open_zone(). Remove superfluous close zone in resp_open_zone().

2020-08-18scsi: scsi_debug: Fix scp is NULL errorsDouglas Gilbert1-0/+2
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).

2020-08-18scsi: ufs: No need to send Abort Task if the task in DB was clearedBean Huo1-7/+8
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.

2020-08-18scsi: ufs: Clean up completed request without interrupt notificationStanley Chu1-1/+2
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".

2020-08-18scsi: ufs: Fix possible infinite loop in ufshcd_holdStanley Chu1-1/+4
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.

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.
