2022-07-26scsi: target: Remove XDWRITEREAD emulated supportMike Christie
This patch removes XDWRITEREAD support because it never fully worked when it was added in the initial LIO merge and it's been fully broken since 2013 from commit a2890087499a ("target: Add compare_and_write_post() completion callback fall through"). The two issues above are: 1. XDWRITEREAD support was just never completed when LIO was merged. We never did the DISABLE WRITE check and so we never write data out. 2. Since the commit above, we never complete the command. After we do the XOR, we return from xdreadwrite_callback and that's it. We never send a response for the command, so the command will always time out and fail. Since this has been fully broken for almost nine years this patch just removes emulated support.

Variable length SCSI commands are transferred over iSCSI via two CDB buffers - in Basic Header Segment and in Additional Header Segment (AHS). Since AHS is not supported yet, a target reads just BHS (48 byte) from TCP and treats the remaining octets as a next new iSCSI PDU that causes protocol errors. Add support for the Extended CDB AHS type.

2022-07-26scsi: core: Fix warning in scsi_alloc_sgtables()Jason Yan
As explained in SG_IO howto[1]: "If iovec_count is non-zero then 'dxfer_len' should be equal to the sum of iov_len lengths. If not, the minimum of the two is the transfer length." When iovec_count is non-zero and dxfer_len is zero, the sg_io() just genarated a null bio, and finally caused a warning below. To fix it, skip generating a bio for this request if dxfer_len is zero.

2022-07-26scsi: mpt3sas: Stop fw fault watchdog work item during system shutdownDavid Jeffery
During system shutdown or reboot, mpt3sas will reset the firmware back to ready state. However, the driver leaves running a watchdog work item intended to keep the firmware in operational state. This causes a second, unneeded reset on shutdown and moves the firmware back to operational instead of in ready state as intended. And if the mpt3sas_fwfault_debug module parameter is set, this extra reset also panics the system. mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the firmware back to ready state.

And use it to bail early in DP detection and avoid futile AUX transactions. This could be used on other connector types too in theory, but it's not something we've ever done before and I'd rather not risk breaking working systems without looking into it more closely. It's safe for DP though. We already do this by checking an AUX register that contains HPD status and aborting the transaction. However, this is much deeper in the stack - after taking various mutexes, poking HW for no good reason, and making a mess in debug logs.
