2017-04-12vfio: ccw: improve error handling for vfio_ccw_mdev_removeDong Jia Shi
When vfio_ccw_mdev_reset fails during the remove process of the mdev, the current implementation simply returns. The failure indicates that the subchannel device is in a NOT_OPER state, thus the right thing to do should be removing the mdev. While we are at here, reverse the condition check to make the code more concise and readable.

2017-04-11scsi: ipr: do not set DID_PASSTHROUGH on CHECK CONDITIONMauricio Faria de Oliveira
On a dual controller setup with multipath enabled, some MEDIUM ERRORs caused both paths to be failed, thus I/O got queued/blocked since the 'queue_if_no_path' feature is enabled by default on IPR controllers. This example disabled 'queue_if_no_path' so the I/O failure is seen at the sg_dd program. Notice that after the sg_dd test-case, both paths are in 'failed' state, and both path/priority groups are in 'enabled' state (not 'active') -- which would block I/O with 'queue_if_no_path'. # sg_dd if=/dev/dm-2 bs=4096 count=1 dio=1 verbose=4 blk_sgio=0 <...> read(unix): count=4096, res=-1 sg_dd: reading, skip=0 : Input/output error <...> # dmesg [...] sd 2:2:16:0: [sds] FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [...] sd 2:2:16:0: [sds] Sense Key : Medium Error [current] [...] sd 2:2:16:0: [sds] Add.

The dm-multipath explicitly checks for the MEDIUM ERROR case (and a few others) so not to fail the path (e.g., I/O to other sectors could potentially happen without problems). See dm-mpath.c :: do_end_io_bio() -> noretry_error() !->! fail_path(). The problem trace is: 1) ipr_scsi_done() // SENSE KEY/CHECK CONDITION detected, go to.. 2) ipr_erp_start() // ipr_is_gscsi() and masked_ioasc OK, go to.. 3) ipr_gen_sense() // masked_ioasc is IPR_IOASC_MED_DO_NOT_REALLOC, // so set DID_PASSTHROUGH. 4) scsi_decide_disposition() // check for DID_PASSTHROUGH and return // early on, faking a DID_OK.. *instead* // of reaching scsi_check_sense(). // Had it reached the latter, that would // set host_byte to DID_MEDIUM_ERROR. 5) scsi_finish_command() 6) scsi_io_completion() 7) __scsi_error_from_host_byte() // That would be converted to -ENODATA <...> 8) dm_softirq_done() 9) multipath_end_io() 10) do_end_io() 11) noretry_error() // And that is checked in dm-mpath :: noretry_error() // which would cause fail_path() not to be called. With this patch applied, the I/O is failed but the paths are not. This multipath device continues accepting more I/O requests without blocking.

2017-04-11scsi: aacraid: fix PCI error recovery pathGuilherme G. Piccoli
During a PCI error recovery, if aac_check_health() is not aware that a PCI error happened and we have an offline PCI channel, it might trigger some errors (like NULL pointer dereference) and inhibit the error recovery process to complete. This patch makes the health check procedure aware of PCI channel issues, and in case of error recovery process, the function aac_adapter_check_health() returns -1 and let the recovery process to complete successfully. This patch was tested on upstream kernel v4.11-rc5 in PowerPC ppc64le architecture with adapter 9005:028d (VID:DID) - the error recovery procedure was able to recover fine.

Firmware is doing RFH, TFH and SCD configuration, while driver only fills the required configurations and addresses in the context information structure. The only remaining access to RFH is the write pointer, which is updated upon alive interrupt after FW configured the RFH.

2017-04-11iwlwifi: mvm: don't assume static queue numbersSara Sharon
In a000 devices FW will assign the queue number. Prepare for that by getting rid of static defines and store them in variables. Enlarge to u16 since we may have up to 512 queues. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-11iwlwifi: mvm: optimize reorder timeout frame releasingSara Sharon
Currently we release up to the last expired frame. However, if there are consecutive frames after it - we can optimize it further and release them as well - until the next hole. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-11iwlwifi: mvm: support new ADD_MODIFY_STA_KEY commandSara Sharon
The command was changed to support PN offload and TKIP offload. The FW will do TKIP calculations in D0 only for a000 devices, but API is aligned anyway. However, for all devices we can stop sending the wowlan tkip command. Firmware will fetch the keys from the station key command.

2017-04-11iwlwifi: mvm: add multicast stationSara Sharon
Currently multicast queue is associated with the broadcast station. This raises quite a few issues: The multicast queue has a special treatment: - It is sent in the MAC context command - It is excluded from tfd_queue_mask In DQA mode we end up enabling two queues - the probe response queue and the multicast queue - with the same station (broadcast) and TID while in DQA mode it should be unique RA-TID. Firmware will enforce it for a000 devices, so this allocation will fail. In addition, in a000 devices the FW will set the FIFO and not the driver. So there is a need for FW to know when we enable the queue that it is multicast queue so it will be bound to the multicast FIFO. There is no such way in current design. In order to simplify driver and firmware handling of this queue create a multicast station. This solves the unique RA-TID issue in the short term and serves as preparation for the long term. In the long term we will also add a flag marking this station for the FW as the multicast station. Once we will do that the FW will know this is the multicast queue immediately when it is added and bind it to the correct FIFO. It will also enable removing the special treatment of the queue in the MAC context command. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
