* [SCSI] libfcoe: FIP link keep-alive should continue while logged offJoe Eykholt2010-07-27
| | | | | | | | | | | | | A check in fcoe_ctlr_send_keep_alive() returns if there's no port_id for the local port. This could miss a keep alive if we just did a host reset and have logged off and will log back in. Return only if we are doing the port keep alive, in which case we need to be logged in.

* [SCSI] ipr: move setting of the allow_restart flag for vsets and disksWayne Boyer2010-07-27
| | | | | | | | | | | | | | | | | | | | A problem was found where the call to scsi_add_device() fails intermittently for an adapter. This is caused when __scsi_add_device() returns -ENODEV as a result of not calling scsi_probe_and_add_lun() since the call to scsi_host_scan_allowed() fails. scsi_host_scan_allowed() fails because the adapter state is set to SHOST_RECOVERY instead of SHOST_RUNNING. The state of the adapter is being set to SHOST_RECOVERY by scsi_eh_scmd_add() during error handling. This problem is avoided by moving the setting of the allow_restart flag to later in the device initialization sequence. This prevents further error handling if we get a NOT_READY response from a TUR command by causing scsi_check_sense() to return SUCCESS. Therefore, scsi_eh_scmd_add() will not run and the adapter state will remain as SHOST_RUNNING.

* [SCSI] be2iscsi: fix disconnection cleanupMike Christie2010-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes 4 bugs in the connection connect/disconnect cleanup path. 1. If beiscsi_open_conn fails beiscsi_free_ep was always being called, and if beiscsi_open_conn failed because beiscsi_get_cid failed then we would free an unallocated cid. 2. If beiscsi_ep_connect failed due to a beiscsi_open_conn failure it was leaking iscsi_endpoints. 3. beiscsi_ep_disconnect was leaking iscsi_endpoints. beiscsi_ep_disconnect should free the iscsi_endpoint. We cannot do it in beiscsi_conn_stop because that is only called for iscsi connection cleanup. If beiscsi_ep_connect returns success, but then the poll function fails or the connect times out then beiscsi_ep_disconnect will be called to clean up the ep. The conn_stop callout will not be called in that path. 4. beiscsi_conn_stop was freeing the iscsi_endpoint then accessing it a couple lines later.

* [SCSI] ipr: add endian swap enablement for 64 bit adaptersWayne Boyer2010-07-27
| | | | | | | | | | | | | | | | | | | A change in the hardware design of the chip for the new adapters changes the default endianness of MMIO operations. This patch adds a register definition which when written to with a predefined value will change the endianness back to what the driver expects. This patch also fixes two problems found during testing. First, the first reserved field in the ipr_hostrcb64_fabirc_desc structure only reserved one byte. The correct amount to reserve is 2 bytes. Second, the reserved field of the ipr_hostrcb64_error structure only reserved 2 bytes. The correct amount to reserve is 16 bytes.

* [SCSI] qla2xxx: Handle outstanding mbx cmds on hung f/w scenarios.Santosh Vernekar2010-07-27
| | | | | | | | | | | | | | | | | | Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable.

* [SCSI] hpsa: fix block fetch table problem.Stephen M. Cameron2010-07-27
| | | | | | | | | | | | | | | | | | We have 32 (MAXSGENTRIES) scatter gather elements embedded in the command. With all these, the total command size is about 576 bytes. However, the last entry in the block fetch table is 35. (the block fetch table contains the number of 16-byte chunks the firmware needs to fetch for a given number of scatter gather elements.) 35 * 16 = 560 bytes, which isn't enough. It needs to be 36. (36 * 16 == 576) or, MAXSGENTRIES + 4. (plus 4 because there's a bunch of stuff at the front of the command before the first scatter gather element that takes up 4 * 16 bytes.) Without this fix, the controller may have to perform two DMA operations to fetch the command since the first one may not get the whole thing.
