In the absense of this patch, we could have a situation where the host may respond to a command that was issued prior to the issuance of the RESET command at some arbitrary time after responding to the RESET command.

| * | [SCSI] scsi_debug: Fix off-by-one bug when unmapping regionLukas Czerner2012-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it is possible to unmap one more block than user requested to due to the off-by-one error in unmap_region(). This is probably due to the fact that the end variable despite its name actually points to the last block to unmap + 1. However in the condition it is handled as the last block of the region to unmap. The bug was not previously spotted probably due to the fact that the region was not zeroed, which has changed with commit be1dd78de5686c062bb3103f9e86d444a10ed783. With that commit we were able to corrupt the ext4 file system on 256M scsi_debug device with LBPRZ enabled using fstrim. Since the 'end' semantic is the same in several functions there this commit just fixes the condition to use the 'end' variable correctly in that context.

| * | [SCSI] Shorten the path length of scsi_cmd_to_driver()Li Zhong2012-10-091-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tries to shorten the path length of scsi_cmd_to_driver(). As only REQ_TYPE_BLOCK_PC commands can be submitted without a driver, so we could avoid the related NULL checking, as long as we make sure we don't use it for REQ_TYPE_BLOCK_PC type commands. Plus, this fixes a bug where you get different behaviors from REQ_TYPE_BLOCK_PC commands when a driver is and isn't attached. Signed-off-by: Li Zhong <zhong@linux.vnet.ibm.com> Reviewed-by: Martin K.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | virtio-scsi needs to report LUNs greater than 256 using the "flat" format. Because the Linux SCSI layer just maps the SCSI LUN to an u32, without any parsing, these end up in the range from 16640 to 32767. Fix max_lun to account for the possibility that logical unit numbers are encoded with the "flat" format.

The fc_fcp_resp() is not completing the completion for the LUN RESET task since fc_fcp_resp assumes that the FCP_RSP_INFO is 8 bytes with the 4 byte reserved field, where in case of NetApp targets the FCP_RSP to LUN RESET only has 4 bytes of FCP_RSP_INFO. This leads fc_fcp_resp to error out w/o completing the task completion, eventually causing LUN RESET to be escalated to host reset, which is not very nice. Per FCP-3 r04, clause 9.5.15 and Table 23, the FCP_RSP_INFO field can be either 4 bytes or 8 bytes, with the last 4 bytes as "Reserved (if any)". Therefore it is valid to have 4 bytes FCP_RSP_INFO like some of the NetApp targets behave. Fixing this by validating the FCP_RSP_INFO against both the two spec allowed length.

Debugging this it was found that the FCoE packets transmitted via the NPIV ports were not tagged with correct user priority as negotiated with peer by DCB agent. This resulted in FCoE traffic going with priority zero(0) that did not have priority flow control (PFC) enabled for it. The initiator after transferring data to the target never saw any reply indicating the transfer was complete. This resulted in error recovery (ABTS) and SCSI command retries by the scsi-mid layer; eventually resulting in I/O errors. This patch fixes this issue by keeping the FCoE user priority information in the fcoe_interface instance that is common for both the physical port as well as NPIV ports connected to that physical port; instead of storing it in fcoe_port structure that has a per port instance.
