| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of Task Management handling, the driver will disable and enable the MSIx index zero which belongs to the Admin reply queue. During this transition the driver loses some interrupts and this leads to Admin request and ioctl timeouts. After enabling the interrupts, poll the Admin reply queue to avoid timeouts.

|/ | | | | | | | | | | | | Upon Virtual disk removal, firmware sends device status change event (Virtual disk remove event) and expects the driver to start device remove handshake (by sending target reset and IOU control command to firmware). However, the driver does not initiate the device remove handshake which leads to the firmware fault.

* scsi: mpi3mr: Use number of bits to manage bitmap sizesShin'ichiro Kawasaki2023-02-211-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To allocate bitmaps, the mpi3mr driver calculates sizes of bitmaps using byte as unit. However, bitmap helper functions assume that bitmaps are allocated using unsigned long as unit. This gap causes memory access beyond the bitmap sizes and results in "BUG: KASAN: slab-out-of-bounds". The BUG was observed at firmware download to eHBA-9600. Call trace indicated that the out-of-bounds access happened in find_first_zero_bit() called from mpi3mr_send_event_ack() for miroc->evtack_cmds_bitmap. To fix the BUG, do not use bytes to manage bitmap sizes. Instead, use number of bits, and call bitmap helper functions which take number of bits as arguments. For memory allocation, call bitmap_zalloc() instead of kzalloc() and krealloc(). For memory free, call bitmap_free() instead of kfree(). For zero clear, call bitmap_clear() instead of memset(). Remove three fields for bitmap byte sizes in struct scmd_priv which are no longer required. Replace the field dev_handle_bitmap_sz with dev_handle_bitmap_bits to keep number of bits of removepend_bitmap across resize.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During controller reset, the driver tries to flush all the pending firmware event works from worker queue that are queued prior to the reset. However, if any work is waiting for device addition/removal operation to be completed at the SML, then a deadlock is observed. This is due to the controller reset waiting for the device addition/removal to be completed and the device/addition removal is waiting for the controller reset to be completed. To limit this deadlock, continue with the controller reset handling without canceling the work which is waiting for device addition/removal operation to complete at SML.

* | treewide: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva2022-02-171-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ... T1 member; T2 array[ - 0 ]; }; UAPI and wireless changes were intentionally excluded from this patch and will be sent out separately.
