2020-11-10scsi: scsi_dh_alua: Return BLK_STS_AGAIN for ALUA transitioning stateHannes Reinecke
When the ALUA state indicates transitioning we should not retry the command immediately, but rather complete the command with BLK_STS_AGAIN to signal the completion handler that it might be retried. This allows multipathing to redirect the command to another path if possible, and avoid stalls during lengthy transitioning times.

2020-11-10scsi: block: Return status code in blk_mq_end_request()Hannes Reinecke
blk_mq_end_request() will use the block status returned from queue_rq() as argument, except in one instance in blk_mq_dispatch_rq_list(), where the generic BLK_STS_IOERR is used.

2020-11-10scsi: MAINTAINERS: Make Bodo target_core_user maintainerMike Christie
Bodo knows the code better than me now, has time to review patches and is excellent at it, and has lots of ideas for how to make the driver better, so this patch adds him as the maintainer. There was no entry in there already. Andy had posted on the list here: https://www.spinics.net/lists/target-devel/msg14690.html when it got transitioned to me. I added an entry because several companies used it and I thought it would be easy for them to find Bodo.

2020-11-04scsi: ufs: Allow an error return value from ->device_reset()Adrian Hunter
It is simpler for drivers to provide a ->device_reset() callback irrespective of whether the GPIO, or firmware interface necessary to do the reset, is discovered during probe. Change ->device_reset() to return an error code. Drivers that provide the callback, but do not do the reset operation should return -EOPNOTSUPP.

2020-11-04scsi: ufs: Add DeepSleep featureAdrian Hunter
DeepSleep is a UFS v3.1 feature that achieves the lowest power consumption of the device, apart from power off. In DeepSleep mode, no commands are accepted, and the only way to exit is using a hardware reset or power cycle. This patch assumes that if a power cycle was an option, then power off would be preferable, so only exit via a hardware reset is supported. Drivers that wish to support DeepSleep need to set a new capability flag UFSHCD_CAP_DEEPSLEEP and provide a hardware reset via the existing ->device_reset() callback. It is assumed that UFS devices with wspecversion >= 0x310 support DeepSleep.

2020-11-04scsi: pm80xx: Fix pm8001_mpi_get_nvmd_resp() race conditionyuuzheng
A use-after-free or null-pointer error occurs when the 251-byte response data is copied from IOMB buffer to response message buffer in function pm8001_mpi_get_nvmd_resp(). After sending the command get_nvmd_data(), the caller begins to sleep by calling wait_for_complete() and waits for the wake-up from calling complete() in pm8001_mpi_get_nvmd_resp(). Due to unexpected events (e.g., interrupt), if response buffer gets freed before memcpy(), a use-after-free error will occur. To fix this, the complete() should be called after memcpy().

2020-11-04scsi: pm80xx: Avoid busywait in FW ready checkakshatzen
In function check_fw_ready() we busy wait using udelay. The CPU is not released and we see need_resched failures. Busy waiting is not necessary since we are in process context and we can sleep instead. Replace udelay with msleep of 20 ms intervals while waiting for firmware to become ready. It has been verified that check_fw_ready is not being used in interrupt context anywhere, hence it is safe to make this change.

2020-11-04scsi: pm80xx: Make running_req atomicViswas G
Incorrect value of the running_req was causing the driver unload to be stuck during the SAS lldd_dev_gone notification handling. During SATA I/O completion, for some error status values, the driver schedules the event handler and running_req is decremented from that. However, there are some other error status values (like IO_DS_IN_RECOVERY, IO_XFER_ERR_LAST_PIO_DATAIN_CRC_ERR) where the I/O has already been completed by fw/driver so running_req is not decremented. Also during NCQ error handling, driver itself will initiate READ_LOG_EXT and ABORT_ALL. When libsas/libata initiate READ_LOG_EXT (0x2F), driver increments running_req. This will be completed by the driver in pm80xx_chip_sata_req(), but running_req was not decremented.

It sounds unwise to let user space pass an unchecked 32-bit offset into a kernel structure in an ioctl. This is an unsigned variable, so checking the upper bound for the size of the structure it points into is sufficient to avoid data corruption, but as the pointer might also be unaligned, it has to be written carefully as well. While I stumbled over this problem by reading the code, I did not continue checking the function for further problems like it.

During HBA reset the Port ID of vSES device may change. As a result, it is necessary to refresh virtual_phy objects after reset. Each Port's vphy_list table needs to be updated after updating the HBA port table. The algorithm is as follows: - Loop over each port entry from HBA port table * Loop over each virtual phy entry from port's vphys_list table - Mark virtual phy entry as dirty by setting dirty bit in virtual phy entry's flags field - Read SASIOUnitPage0 page - Loop over each HBA Phy's Phy data from SASIOUnitPage0 * If phy's remote attached device is not SES device then continue with processing next HBA Phy's Phy data; * Read SASPhyPage0 data for this Phy number and determine whether current phy is a virtual phy or not. If it is not a virtual phy then continue with next Phy data; * Get the current phy's remote attached vSES device's SAS Address; * Loop over each port entry from HBA port table - If Port's vphys_mask field is zero then continue with next Port entry, - Loop over each virtual phy entry from Port's vphy_list table - If the current phy's remote SAS Address is different from virtual phy entry's SAS Address then continue with next virtual phy entry, - Set bit corresponding to current phy number in virtual phy entry's phy_mask field, - Get the HBA port table's Port entry corresponding to Phy data's 'Port' value, * If there is no Port entry corresponding to Phy data's 'Port' value in HBA port table then create a new port entry and add it to HBA port table. - If this retrieved Port entry is the same as the current Port entry then don't do anything, just clear the dirty bit from virtual phy entry's flag field and continue with processing next HBA Phy's Phy data. - If this retrieved Port entry is different from the current Port entry then move the current virtual phy entry from current Port's vphys_list to retrieved Port entry's vphys_list. * Clear current phy bit in current Port entry's vphys_mask and set the current phy bit in the retrieved Port entry's vphys_mask field. * Clear the dirty bit from virtual phy entry's flag field and continue with next HBA Phy's Phy data. - Delete the 'virtual phy' entries and HBA's 'Port table' entries which are still marked as 'dirty'.
