When processing the response to either a LUN reset, target reset, or an abort task set, the ibmvfc driver needs to treat as success receiving a response with a non-zero status in the response IU along with a general transport error with the FCP response code being zero. The VIOS currently guarantees this cannot happen, but a future version of VIOS may allow this to be returned, so ensure we handle this response combination correctly for TMFs, as we already do for SCSI commands.

This version fixes 64-bit modulo on 32-bit as well as inadvertent map updates when TP was disabled. Implement support for thin provisioning in scsi_debug. No actual memory de-allocation is taking place. The intent is to emulate a thinly provisioned storage device, not to be one. There are four new module options: - unmap_granularity specifies the granularity at which to track mapped blocks (specified in number of logical blocks). 2048 (1 MB) is a realistic value for disk arrays although some may have a finer granularity. - unmap_alignment specifies the first LBA which is naturally aligned on an unmap_granularity boundary. - unmap_max_desc specifies the maximum number of ranges that can be unmapped using one UNMAP command. If this is 0, only WRITE SAME is supported and UNMAP will cause a check condition. - unmap_max_blocks specifies the maximum number of blocks that can be unmapped using a single UNMAP command. Default is 0xffffffff. These parameters are reported in the new and extended block limits VPD. If unmap_granularity is specified the device is tagged as thin provisioning capable in READ CAPACITY(16). A bitmap is allocated to track whether blocks are mapped or not. A WRITE request will cause a block to be mapped. So will WRITE SAME unless the UNMAP bit is set. Blocks can be unmapped using either WRITE SAME or UNMAP. No accounting is done to track partial blocks. This means that only whole blocks will be marked free. This is how the array people tell me their firmwares work. GET LBA STATUS is also supported. This command reports whether a block is mapped or not, and how long the adjoining mapped/unmapped extent is. The block allocation bitmap can also be viewed from user space via: /sys/bus/pseudo/drivers/scsi_debug/map Signed-off-by:

Correct issues where the lower scsi-status would be improperly cleared, instead, allow the midlayer to process the status after the proper residual-count checks are performed. Finally, validate firmware status flags prior to assigning values from the FCP_RSP frame. Signed-off-by:

I was doing some large lun count testing with 2.6.31 and hit a BUG_ON() in fc_timeout_deleted_rport(), and it seems like it should have been just a matter of time before someone did. It seems invalid to set port_state under lock, then expect it to remain set after releasing the lock. Another thread called fc_remote_port_add() when the lock was released, changing the port_state. This patch removes the BUG_ON and moves the test of the port_state to inside the host_lock. It's been running for several weeks now with no ill effect. Signed-off-by:

When the Integrity check is done in scsi_io_completion it will set error to -EILSEQ. However, at this point error is no longer used, and blk_end_request_err has -EIO hardcoded. It looks like there was just porting mistake with this patch http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3e695f89c5debb735e4ff051e9e58d8fb4e95110 and we meant to send error upwards, so this patch changes the hard coded EIO to the error variable. I have only boot tested this patch. Signed-off-by:

Errata: Certain conditions on the scsi bus may casue the 53C1030 to incorrectly signal a SCSI_DATA_UNDERRUN to the host. Workaround 1: For an Errata on LSI53C1030 When the length of request data and transfer data are different with result of command (READ or VERIFY), DID_SOFT_ERROR is set. Workaround 2: For potential trouble on LSI53C1030. It is checked whether the length of request data is equal to the length of transfer and residual. MEDIUM_ERROR is set by incorrect data.

Driver will update the OS devices after adding and deleting the device from FW. When driver receive add or delete AEN from FW, driver will send the DCMD cmd to get the System PD list from FW. Then driver will check if this device already in the OS: If add event and OS don't have the device (but it is in the list), driver add the device to OS, otherwise driver will not add. If remove event, driver will check the list, if is not in the list, but OS have the device, driver will remove the device. Signed-off-by Bo Yang<bo.yang@lsi.com> Signed-off-by: -

(1) target resets are sending link change rate events with no link rate change -> thus said the driver was modified so when there is no link rate change, we don't need to call mpt2sas_transport_update_links nor _scsih_ublock_io_device. (2) There were changes made in _scsih_sas_topology_change_event_debug to change the debug strings so they are more clear. Also the link rate change information was added to display the new and previous link rate. for the MPI2_EVENT_SAS_TOPOLOGY_CHANGE_LIST event when the ExpStatus is set to zero, display "responding" instead of "unknown status".

(1) Added new function _scsih_ir_shutdown. This function will issue the MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED request via MPI2_FUNCTION_RAID_ACTION. The function will wait 10 seconds for reply message frame, then print out the ioc status and loginfo. This function is only called when there are raid volumes present. (2) Add shutdown callback in the struct pci_driver object scsih_driver. This will be called only when the system is shutting down. From this function, we will call _scsih_ir_shutdown mentioned above. (3) Add support in _scsih_remove to call _scsih_ir_shutdown. The function _scsih_remove will be called when the driver is unloaded (and system is still running). scsih internal command contex is added to send internal message frames from mpt2sas_scsih.c.

When receiving the MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET event, the driver will set the tm_busy flag in the sdev private host data, When tm_busy flag is set, the driver will return SCSI_MLQUEUE_DEVICE_BUSY, effectly freezing the IO to the device. The tm_busy flag is cleared with the MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET event. Signed-off-by:

(1) EEDP(End to End data protection) was not working. This was due to not setting EEDP BlockSize and Flags to little endian format in the message frame. (2) Some expander sysfs attributes were not getting set properly. The sas format was not getting set due to endian issues with sas_format field in the struct rep_manu_reply. Since sas_format was not set properly, the component_vendor_id, component_revision_id, and component_id were not set. (3) In _transport_smp_handler: we don't need to convert the smid from little endian to cpu prior to calling mpt2sas_base_free_smid, because its allready in cpu format. (4) Some loginfos and ioc status were not xonverted from little endian to cpu. Signed-off-by:

cpu_to_le64 when calculating the physical dma address. This will properly handle endianess on big endian systems. The return value of this function was changed from dma_addr_t to __le64. Remove the typecasting of u32 when setting the SenseBufferLowAddress, since its already in __le32 format. Signed-off-by:
