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. Signed-off-by:

This patch adds support for REPORT TARGET PORT GROUPS. This is used eg for the multipathing priority callout to determine the path priority. With this patch multipath-tools can use the existing mpath_prio_alua callout to exercise the path priority grouping. Signed-off-by:

According to the iscsi RFC, we cannot send other requests if we have sent a logout pdu. This patch enforces this requirement by blocking the session and suspending the send thread. Userspace decides if we restart the connection or if we just free everything. Signed-off-by:

We have been dropping the pdu. We should just send it to userspace and let it handle it. Signed-off-by:

from bhalevy@gmail.com: It looks like change 652 to libiscsi.c added some dead code around line 670 if (rc) { spin_unlock_bh(&conn->session->lock); goto again; } since 5 lines above we goto again if (rc). It looks like the previous if (rc) should go away if we want to put the ctask before breaking out of the while loop with "goto again" (see following patch). Signed-off-by: -

If connection creation fails we end up calling list_del on a invalid struct. This then causes an oops. We are not acutally using the lists (old MCS code we thought might be useful elsewhere) so this patch just removes that code. Signed-off-by:

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. Signed-off-by:

Doesn't make the hardware hot pluggable but does ensure the driver won't crash when another device is hot-unplugged at the wrong moment. Soon I propose to deprecate pci_find_device() and some of its friends. Signed-off-by:

The "ibmvscsi: treat busy and error conditions separately" patch submitted by Dave Boutcher back in June incorrectly reenables the CRQ. The broken logic causes the adapter to get disabled if the CRQ connection happens to close temporarily. This patch "fixes that obviously wrong logic check" (Dave's words). Signed-off-by:

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. Signed-off-by:

Thanks to James Smart for the inspiration. Stall error handler if attempting recovery while an rport is blocked. This avoids device offline scenarios due to errors in the error handler. Also verify that VirtDevice is available before issuing scsi command. VirtDevice is removed when fc transport removes a target. See James Smart's patch of 08/17/2006 for greater detail. http://marc.theaimsgroup.com/?l=linux-scsi&m=115583213624803&w=2 Also bump version number per Eric's request. Signed-off-by:
