2020-11-15vhost scsi: Add support for LUN resets.Mike Christie
In newer versions of virtio-scsi we just reset the timer when an a command times out, so TMFs are never sent for the cmd time out case. However, in older kernels and for the TMF inject cases, we can still get resets and we end up just failing immediately so the guest might see the device get offlined and IO errors. For the older kernel cases, we want the same end result as the modern virtio-scsi driver where we let the lower levels fire their error handling and handle the problem. And at the upper levels we want to wait. This patch ties the LUN reset handling into the LIO TMF code which will just wait for outstanding commands to complete like we are doing in the modern virtio-scsi case. Note: I did not handle the ABORT case to keep this simple. For ABORTs LIO just waits on the cmd like how it does for the RESET case. If an ABORT fails, the guest OS ends up escalating to LUN RESET, so in the end we get the same behavior where we wait on the outstanding cmds.

2020-11-15vhost scsi: fix cmd completion raceMike Christie
We might not do the final se_cmd put from vhost_scsi_complete_cmd_work. When the last put happens a little later then we could race where vhost_scsi_complete_cmd_work does vhost_signal, the guest runs and sends more IO, and vhost_scsi_handle_vq runs but does not find any free cmds. This patch has us delay completing the cmd until the last lio core ref is dropped. We then know that once we signal to the guest that the cmd is completed that if it queues a new command it will find a free cmd.

2020-11-15vhost scsi: alloc cmds per vq instead of sessionMike Christie
We currently are limited to 256 cmds per session. This leads to problems where if the user has increased virtqueue_size to more than 2 or cmd_per_lun to more than 256 vhost_scsi_get_tag can fail and the guest will get IO errors. This patch moves the cmd allocation to per vq so we can easily match whatever the user has specified for num_queues and virtqueue_size/cmd_per_lun. It also makes it easier to control how much memory we preallocate. For cases, where perf is not as important and we can use the current defaults (1 vq and 128 cmds per vq) memory use from preallocate cmds is cut in half. For cases, where we are willing to use more memory for higher perf, cmd mem use will now increase as the num queues and queue depth increases.

Change the order in tcan4x5x_can_remove() to be the exact inverse of tcan4x5x_can_probe(). First m_can_class_unregister(), then power down the device.

2020-11-15can: tcan4x5x: replace depends on REGMAP_SPI with depends on SPIEnric Balletbo i Serra
regmap is a library function that gets selected by drivers that need it. No driver modules should depend on it. Instead depends on SPI and select REGMAP_SPI. Depending on REGMAP_SPI makes this driver only build if another driver already selected REGMAP_SPI, as the symbol can't be selected through the menu kernel configuration.

2020-11-15can: flexcan: fix failure handling of pm_runtime_get_sync()Zhang Qilong
pm_runtime_get_sync() will increment pm usage at first and it will resume the device later. If runtime of the device has error or device is in inaccessible state(or other error state), resume operation will fail. If we do not call put operation to decrease the reference, it will result in reference leak in the two functions flexcan_get_berr_counter() and flexcan_open(). Moreover, this device cannot enter the idle state and always stay busy or other non-idle state later. So we should fix it through adding pm_runtime_put_noidle().

property comment In the patch d9b081e3fc4b ("can: flexcan: remove ack_grp and ack_bit handling from driver") the unused ack_grp and ack_bit were removed from the driver. However in the comment, the "req_bit" was accidentally removed, too. This patch adds back the "req_bit" bit.

2020-11-15can: peak_usb: fix potential integer overflow on shift of a intColin Ian King
The left shift of int 32 bit integer constant 1 is evaluated using 32 bit arithmetic and then assigned to a signed 64 bit variable. In the case where time_ref->adapter->ts_used_bits is 32 or more this can lead to an oveflow. Avoid this by shifting using the BIT_ULL macro instead.
