2022-01-31scsi: ufs: Add checking lifetime attribute for WriteBoosterJinyoung Choi
Because WB performs writes in SLC mode, it is not possible to use WriteBooster indefinitely. Vendors can set a lifetime limit in the device. If the lifetime exceeds this limit, the device ican disable the WB feature. The feature is defined in the "bWriteBoosterBufferLifeTimeEst (IDN = 1E)" attribute. With lifetime exceeding the limit value, the current driver continuously performs the following query: - Write Flag: WB_ENABLE / DISABLE - Read attr: Available Buffer Size - Read attr: Current Buffer Size This patch recognizes that WriteBooster is no longer supported by the device, and prevents unnecessary queries.

2022-01-31scsi: pm8001: Fix use-after-free for aborted SSP/STP sas_taskJohn Garry
Currently a use-after-free may occur if a sas_task is aborted by the upper layer before we handle the I/O completion in mpi_ssp_completion() or mpi_sata_completion(). In this case, the following are the two steps in handling those I/O completions: - Call complete() to inform the upper layer handler of completion of the I/O. - Release driver resources associated with the sas_task in pm8001_ccb_task_free() call. When complete() is called, the upper layer may free the sas_task. As such, we should not touch the associated sas_task afterwards, but we do so in the pm8001_ccb_task_free() call. Fix by swapping the complete() and pm8001_ccb_task_free() calls ordering.

2022-01-31scsi: pm8001: Fix use-after-free for aborted TMF sas_taskJohn Garry
Currently a use-after-free may occur if a TMF sas_task is aborted before we handle the IO completion in mpi_ssp_completion(). The abort occurs due to timeout. When the timeout occurs, the SAS_TASK_STATE_ABORTED flag is set and the sas_task is freed in pm8001_exec_internal_tmf_task(). However, if the I/O completion occurs later, the I/O completion still thinks that the sas_task is available. Fix this by clearing the ccb->task if the TMF times out - the I/O completion handler does nothing if this pointer is cleared.

2022-01-31scsi: core: Reallocate device's budget map on queue depth changeMing Lei
We currently use ->cmd_per_lun as initial queue depth for setting up the budget_map. Martin Wilck reported that it is common for the queue_depth to be subsequently updated in slave_configure() based on detected hardware characteristics. As a result, for some drivers, the static host template settings for cmd_per_lun and can_queue won't actually get used in practice. And if the default values are used to allocate the budget_map, memory may be consumed unnecessarily. Fix the issue by reallocating the budget_map after ->slave_configure() returns. At that time the device queue_depth should accurately reflect what the hardware needs.

2022-01-31scsi: pm80xx: Fix double completion for SATA devicesAjish Koshy
Current code handles completions for SATA devices in mpi_sata_completion() and mpi_sata_event(). However, at the time when any SATA event happens, for almost all the event types, the command is still in the target. It is therefore incorrect to complete the task in sata_event(). There are some events for which we get sata_completions, some need recovery procedure and others abort. All the tasks must be completed via sata_completion() path. Removed the task done related code from sata_events(). For tasks where we don't get completions, let top layer call abort() to abort the command post timeout.

2022-01-25scsi: scsi_debug: Add no_rwlock parameterDouglas Gilbert
By default, this driver places a read lock around all user data fetches and a write lock around all user data modifying operations (e.g. WRITE commands). These locks have "per store" granularity. Other drivers that have a similar function (e.g. null_blk) do not take this data integrity step and run significantly faster in some tests. In the common case of a (simulated) device to device copy (e.g. what dd and its variants do) there should be no need for locks around data accesses. So add the driver and sysfs parameter no_rwlock which is boolean and when set does what its name suggests. The default is false for backward comaptibility.

This makes debug a little easier to follow when it is turned on (e.g. 'echo 0x1 > opts'). Bump driver version number.

2022-01-25scsi: scsi_debug: Use TASK SET FULL moreDouglas Gilbert
When the internal in_use bit array in this driver is full returning SCSI_MLQUEUE_HOST_BUSY leads to the mid-level reissuing the request which is unhelpful. Previously TASK SET FULL status was only returned if ALL_TSF [0x400] is placed in the opts variable (at load time or via sysfs). Now ignore that setting and always return TASK SET FULL when in_use array is full. Also set DID_ABORT together with TASK SET FULL so the mid-level gives up immediately. Aside: the situations addressed by this patch lead to lockups and timeouts. They have only been detected when blk_poll() is used. That mechanism is relatively new in the SCSI subsystem suggesting the mid-level may need more work in that area.

2022-01-25scsi: scsi_debug: Address races following module loadDouglas Gilbert
When scsi_debug is loaded as a module with many (simulated) hosts, targets, and devices (LUs), modprobe can take a long time to return. Only a small amount of this time is spent in the scsi_debug_init(); the rest is other parts of the kernel reacting to to the appearance of new storage devices. As soon as scsi_debug_init() has completed the user space may call 'rmmod scsi_debug' and this was found to cause race problems as outlined here: https://bugzilla.kernel.org/show_bug.cgi?id=212337 To reliably generate this race a sysfs parameter called rm_all_hosts was added and the code was strengthened in this area. The main change was to make the count of scsi_debug hosts present an atomic. Then it was found that the handling of the existing add_host parameter needed the same strengthening. Further: 'echo -9999 > /sys/bus/pseudo/drivers/scsi_debug/add_host has the same effect as rm_all_hosts so rm_all_hosts was not needed. To inhibit a race between two invocations of writes to add_host, a mutex was added. Also address a possible race when rmmod is called but LUs are still being added. The logic to remove (all) hosts is rather crude: it works backwards down a linked lists of hosts. Any pending requests are terminated with DID_NO_CONNECT as are any new requests. In the case where not all hosts are being removed, the ones that remain may have lost requests as just outlined. The lowest numbered host (id) hosts will remain.

2022-01-24scsi: qla2xxx: Implement ref count for SRBSaurav Kashyap
The timeout handler and the done function are racing. When qla2x00_async_iocb_timeout() starts to run it can be preempted by the normal response path (via the firmware?). qla24xx_async_gpsc_sp_done() releases the SRB unconditionally. When scheduling back to qla2x00_async_iocb_timeout() qla24xx_async_abort_cmd() will access an freed sp->qpair pointer: qla2xxx [0000:83:00.0]-2871:0: Async-gpsc timeout - hdl=63d portid=234500 50:06:0e:80:08:77:b6:21. qla2xxx [0000:83:00.0]-2853:0: Async done-gpsc res 0, WWPN 50:06:0e:80:08:77:b6:21 qla2xxx [0000:83:00.0]-2854:0: Async-gpsc OUT WWPN 20:45:00:27:f8:75:33:00 speeds=2c00 speed=0400. qla2xxx [0000:83:00.0]-28d8:0: qla24xx_handle_gpsc_event 50:06:0e:80:08:77:b6:21 DS 7 LS 6 rc 0 login 1|1 rscn 1|0 lid 5 BUG: unable to handle kernel NULL pointer dereference at 0000000000000004 IP: qla24xx_async_abort_cmd+0x1b/0x1c0 [qla2xxx] Obvious solution to this is to introduce a reference counter. One reference is taken for the normal code path (the 'good' case) and one for the timeout path. As we always race between the normal good case and the timeout/abort handler we need to serialize it. Also we cannot assume any order between the handlers. Since this is slow path we can use proper synchronization via locks. When we are able to cancel a timer (del_timer returns 1) we know there can't be any error handling in progress because the timeout handler hasn't expired yet, thus we can safely decrement the refcounter by one. If we are not able to cancel the timer, we know an abort handler is running. We have to make sure we call sp->done() in the abort handlers before calling kref_put().

2022-01-24scsi: pm8001: Fix bogus FW crash for maxcpus=1John Garry
According to the comment in check_fw_ready() we should not check the IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers. However we check this very field in process_oq() for processing the highest index interrupt vector. The highest interrupt vector is checked as the FW is programmed to signal fatal errors through this irq. Change that function to not check IOP1_READY for those mentioned controllers, but do check ILA_READY in both cases. The reason I assume that this was not hit earlier was because we always allocated 64 MSI(X), and just did not pass the vector index check in process_oq(), i.e. the handler never ran for vector index 63.

If FCoE is not configured, libfc/libfcoe keeps on retrying FLOGI and after 3 retries driver does a context reset and tries fipvlan again. This leads to context reset message flooding the logs.

2022-01-22scsi/sg: move sg-big-buff sysctl to scsi/sg.cXiaoming Ni
kernel/sysctl.c is a kitchen sink where everyone leaves their dirty dishes, this makes it very difficult to maintain. To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic. So move the sg-big-buff sysctl from kernel/sysctl.c to drivers/scsi/sg.c and use register_sysctl() to register the sysctl interface.
