Rozycki + +[ Upstream commit c087df8d1e7dc2e764d11234d84b5af46d500f16 ] + +No Oxford Semiconductor PCI or PCIe parallel port device supports the +Parallel Port FIFO mode. All support the PS/2 Parallel Port mode and +the Enhanced Parallel Port mode via the ECR register. The original 5V +PCI OX16PCI954 device does not support the Extended Capabilities Port +mode, the Test mode or the Configuration mode, but all the other OxSemi +devices do, including in particular the 3.3V PCI OXmPCI954 device and +the universal voltage PCI OXuPCI954 device. All the unsupported modes +are marked reserved in the relevant datasheets. + +Accordingly enable the `base_hi' BAR for the 954 devices to enable PS2 +and EPP mode support via the ECR register, however mask the COMPAT mode +and, until we have a way to determine what chip variant it is that we +poke at, also the ECP mode, and mask the COMPAT mode only for all the +remaining OxSemi devices, fixing errors like: + +parport0: FIFO is stuck +FIFO write timed out + +and a non-functional port when the Parallel Port FIFO mode is selected. + +Complementing the fix apply an ECR mask for all these devices, which are +documented to only permit writing to the mode field of the ECR register +with a bit pattern of 00001 required to be written to bits 4:0 on mode +field writes. No nFault or service interrupts are implemented, which +will therefore never have to be enabled, though bit 2 does report the +FIFO threshold status to be polled for in the ECP mode where supported. + +We have a documented case of writing 1 to bit 2 causing a lock-up with +at least one OX12PCI840 device (from old drivers/parport/ChangeLog): + +2001-10-10 Tim Waugh + + * parport_pc.c: Support for OX12PCI840 PCI card (reported by + mk@daveg.com).

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. + +Link: https://lore.kernel.org/r/20230214005019.1897251-4-shinichiro.kawasaki@wdc.com +Fixes: c5758fc72b92 ("scsi: mpi3mr: Gracefully handle online FW update operation") +Fixes: e844adb1fbdc ("scsi: mpi3mr: Implement SCSI error handler hooks") +Fixes: c1af985d27da ("scsi: mpi3mr: Add Event acknowledgment logic") +Fixes: 824a156633df ("scsi: mpi3mr: Base driver code") +Signed-off-by: Shin'ichiro Kawasaki +Acked-by: Sathya Prakash Veerichetty +Signed-off-by: Martin K.

+If wait_for_completion_timeout() times-out in _cdns_xfer_msg() it +is possible that something could have been written to the RX FIFO. +In this case, we should drain the RX FIFO so that anything in it +doesn't carry over and mess up the next transfer. + +Obviously, if we got to this state something went wrong, and we +don't really know the state of everything. The cleanup in this +situation cannot be bullet-proof but we should attempt to avoid +breaking future transaction, if only to reduce the amount of +error noise when debugging the failure from a kernel log. + +Note that this patch only implements the draining for blocking +(non-deferred) transfers. The deferred API doesn't have any proper +handling of error conditions and would need some re-design before +implementing cleanup.
