2006-11-16[PATCH] scsi: clear garbage after CDBs on SG_IOTejun Heo
ATAPI devices transfer fixed number of bytes for CDBs (12 or 16). Some ATAPI devices choke when shorter CDB is used and the left bytes contain garbage. Block SG_IO cleared left bytes but SCSI SG_IO didn't. This patch makes SCSI SG_IO clear it and simplify CDB clearing in block SG_IO.

2006-11-13[PATCH] SCSI core: always store >= 36 bytes of INQUIRY dataAlan Stern
This patch (as810c) copies a minimum of 36 bytes of INQUIRY data, even if the device claims that not all of them are valid. Often badly behaved devices put plausible data in the Vendor, Product, and Revision strings but set the Additional Length byte to a small value. Using potentially valid data is certainly better than allocating a short buffer and then reading beyond the end of it, which is what we do now.

2006-11-10[SCSI] iscsi_tcp: fix xmittask oopsMike Christie
XMSTATE_SOL_HDR could be set when the xmit thread tests it, but there may not be anything on the r2tqueue yet. Move the XMSTATE_SOL_HDR set before the addition to the queue to make sure that when we pull something off it it is valid. This does not add locks around the xmstate test or make that a atmoic_t because this is a fast path and if it is set when we test it we can handle it there without the overhead. Later on we check the xmitqueue for all requests with the session lock so we will not miss it.

2006-10-25[SCSI] aic79xx: Fixup external device resetHannes Reinecke
Whenever an external device is resetted we really have to take care to keep the channel in sync. Just notifying SCSI-ML and retry is not enough as we have to make sure the SCSI bus is not getting confused, either. So whenever we detect an external reset we rewrite the command to TUR, disable packetized command and notify the internal engine that an abort has happened. This way we trigger a proper bus reset sequence and all devices will be renegotiated properly. Kudos to Justin Gibbs and Luben Tuikov for this idea.

2006-10-25[SCSI] iscsi class: fix slab corruption during restartMike Christie
The transport class recv mempools are causing slab corruption. We could hack around netlink's lack of mempool support like dm, but it is just too ulgy (dm's hack is ugly enough :) when you need to support broadcast. This patch removes the recv pools. We have not used them even when we were allocting 20 MB per session and the system only had 64 MBs. And we have no pools on the send side and have been ok there. When Peter's work gets merged we can use that since the network guys are in favor of that approach and are not going to add mempools everywhere.

Early ISP2432 parts have a known hardware issue when coming out of a D3 hot state. This issue can result in a hung PCIe link. Recent firmwares contain a workaround whereby the stop-firmware mailbox command prevents the ISP from entering the D3 hot state. In order to ensure that the workaround succeeded the driver must verify that the stop-firmware mailbox command completes successfully. In the event of a failure, the driver attempts a shutdown-retry after resetting the ISP and re-executing firmware.
