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:

[SCSI] mpt2sas: Return DID_TRANSPORT_DISRUPTED in nexus loss,SCSI_MLQUEUE_DEVICE_BUSY if device is busy 1 Its observed that the OS was sending request to the driver after it had been put into blocking state, so the driver was modified to return SCSI_MLQUEUE_DEVICE_BUSY. 2. Driver will return DID_TRANSPORT_DISRUPTED when sdev is haivng nexus loss. This occurrs when sdev is blocked, between the MPI2_EVENT_SAS_TOPO_RC_DELAY_NOT_RESPONDING and MPI2_EVENT_SAS_TOPO_RC_TARG_NOT_RESPONDING events. Signed-off-by:

The driver needs to retrieve the ioc facts prior to putting the controller into READY state. The current design is calling ioc facts after putting the controller into READY state, which means the driver is sending a diag reset instead of message unit reset becuase the capability information is not yet available.

Added command line option diag_buffer_enable. When the command line option is set, the driver will automatically post diag buffers at driver load time. The command line option diag_buffer_enable is bitwise, so it's possible to enable both and/or snapshot + trace buffers. For trace, the driver will allocate 1MB buffer, whereas for snapshot its 2MB. The purpose for this is so the enduser doesn't have to manually use an application to setup diag buffers for debugging firmware related issues. Here is some examples trace: # insmod mpt2sas.ko diag_buffer_enable=1 snapshot: # insmod mpt2sas.ko diag_buffer_enable=2 both trace and snapshot: # insmod mpt2sas.ko diag_buffer_enable=3 Signed-off-by:

Added command line option and shost sysfs attribute called mpt2sas_fwfault_debug. When enduser writes a "1" to this parameter, this will enable support in the driver for debugging firmware timeout related issues. This handling was added in three areas (a) scsi error handling callback called task_abort, (b) IOCTL interface, and (c) other timeouts that result in diag resets, such as manufacturing config pages. When this support is enabled, the driver will provide dump_stack to console, halt controller firmware, and panic driver. The end user probably would want to setup serial console redirection so the dump stack can be seen. Here are the three methods for enable this support: (a) # insmod mpt2sas.ko mpt2sas_fwfault_debug=1 (b) # echo 1 > /sys/module/mpt2sas/parameters/mpt2sas_fwfault_debug (c) # echo 1 > /sys/class/scsi_host/host#/fwfault_debug (where # is the host number) Signed-off-by:

Add support in the driver to check for valid response info in the scsi state, then check to see if the response code is MPI2_SCSITASKMGMT_RSP_INVALID_FRAME; when this condition occurrs, the driver will return DID_SOFT_ERROR. A return code of DID_SOFT_ERROR will result in a retry at the scsi-mid layer level. An additional change added to obtain the response code from the 1st byte of the response info instead of last.
