Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[SCSI] zfcp: Block FC transport rports early on errors Use the I/O blocking mechanism in the FC transport class to allow faster failovers for multipathing: - Call fc_remote_port_delete early to set the rport to BLOCKED. - Check the rport status in queuecommand with fc_remote_portchkready to no longer accept new I/O for this port and fail the I/O with the appropriate scsi_cmnd result. - Implement the terminate_rport_io handler to abort all pending I/O requests - Return SCSI commands with DID_TRANSPORT_DISRUPTED while erp is running. - When updating the remote port status, check for late changes and update the remote ports status accordingly.

[SCSI] zfcp: enhancement of zfcp debug features Debug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed and san_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did not change. The new traces improve debugging of problems with zfcp, scsi-stack, multipath and hardware in the SAN. san_dbf traces things like ELS and CT commands, hba_dbf saves HBA specific information of requests, and scsi_dbf saves FCP and SCSI specific information of requests. Common to all new DBFs is that they provide a so called structured view. This significantly improves readability of the traces.

extern void zfcp_fc_port_did_lookup(struct work_struct *);
[SCSI] zfcp: Handle WWPN mismatch in PLOGI payload For ports, zfcp gets the DID from the FC nameserver and tries to open the port. If the open succeeds, zfcp compares the WWPN from the nameserver with the WWPN in the PLOGI payload. In case of a mismatch, zfcp assumes that the DID of the port just changed and we opened the wrong port. This means that zfcp has to forget the DID, lookup the DID again and retry. This error case had a problem that zfcp forgets the DID, but never looks up a new one, stalling the ERP in this case. Fix this by triggering the DID lookup and properly exit from the ERP. The DID lookup will trigger a new ERP action. Also ensure when trying to open the port again with the new DID, first close the open port, even in the NOESC case.

[SCSI] zfcp: attach and release SAN nameserver port on demand Changing the zfcp behaviour from always having the nameserver port open to an on-demand strategy. This strategy reduces the use of limited resources like port connections. The patch provides a common infrastructure which could be used for all WKA ports in future. Also reduce the number of nameserver lookups by changing the zfcp behaviour of always querying the nameserver for the corresponding destination ID of the remote port. If the destination ID has changed during the reopen process we will be informed and then trigger a nameserver query on demand.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
