Return DID_NO_CONNECT when a path failure is detected. When a path fails during I/O and AIO path gets disabled for a multipath device, the I/O was retried in the RAID path slowing down path fail detection. Returning DID_NO_CONNECT allows multipath to switch paths more quickly. Link: https://lore.kernel.org/r/164375209313.440833.9992416628621839233.stgit@brunhilda.pdev.netReviewed-by:

If a SCSI device handler module is loaded after some SCSI devices have already been probed (e.g. via request_module() by dm-multipath), the "access_state" and "preferred_path" sysfs attributes remain invisible for these devices, although the handler is attached and live. The reason is that the visibility is only checked when the sysfs attribute group is first created. This results in an inconsistent user experience depending on the load order of SCSI low-level drivers vs. device handler modules. This patch changes user space API: attempting to read the "access_state" or "preferred_path" attributes will now result in -EINVAL rather than -ENODEV for devices that have no device handler, and tests for the existence of these attributes will have a different result.

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.

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.

To distinguish between resets sent by the SCSI mid-level error handling and newly introduced devices (LUs), this Unit Attention: power on, reset, or bus reset occurred [0x29,0x0] has been subdivided into that UA for the reset case and this new UA: power on occurred [0x29,0x1] for the new device (LU) case. This makes debug a little easier to follow when it is turned on (e.g. 'echo 0x1 > opts'). Bump driver version number.

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.

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.

Fix stuck sessions in get port database. When a thread is in the process of re-establishing a session, a flag is set to prevent multiple threads / triggers from doing the same task. This flag was left on, where any attempt to relogin was locked out. Clear this flag, if the attempt has failed.

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().

Move common open-coded asynchronous command initializing code such as setting up the timer and the done callback into one function. This is a preparation step and allows us later on to change the low level error flow handling at a central place.
