Currently we can only issue the task management (TM) commands via the mailbox mechanism. This is a limitation, since only one mailbox command can be issued at a time. The purpose of this effort is to provide support for issuing and processing the respose to TM and Marker IOCBs asynchronously. Towards achieving this, the consolidated srb architecture that is currently used for BSG and IOCB/Logio commands has been enhanced and used. Signed-off-by:

Currently, BSG and IOCB/Logio commands have a different framework (srb structs). The purpose of this effort is to consolidate them into a generalized framework for these as well as other asynchronous operations in the future. Signed-off-by:

Migrate to a consistent set of debug entries during status-IOCB handling: * group CS_TIMEOUT handling with CS_PORT_UNAVAILABLE and the like (more regrouping of common behaviour). * drop CS_DATA_OVERRUN handling as it now falls into the 'default' case (still returns DID_ERROR). * consolidate CS_RESET and CS_ABORTED handling, as we the only functional difference was a printk() (still returns DID_RESET). * dropped all the earlier inconsistent [qla_]printk()s sprinkled throught the needlessly large case-statement. Failure case I/Os are now logged with a 'standard' format: <command failure details> <command generic details> so, for example a dropped-frame is logged as: qla2xxx 0000:13:00.0: scsi(16:0:0) Dropped frame(s) detected (4000 of 4000 bytes). qla2xxx 0000:13:00.0: scsi(16:0:0) FCP command status: 0x15-0x18 (70018) \ oxid=78 ser=76 cdb=280000 len=4000 rsp_info=0 resid=0 fw_resid=4000 which should now convey all relevant information.

The driver should not be unloaded if any application is using it. To disallow driver unload, driver use count must be incremented. Application uses this char device as handle and increases driver use count to avoid possible driver unload. Signed-off-by:

Currently error status is cleared only after the uncorrectable fatal errors in the qla2xxx_pci_slot_reset. This fix is added to clear the error status in qla2xxx_pci_resume. This way for both fatal and non-fatal errors the error status gets cleared properly. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=572258Signed-off-by:

With qla2xxx using mid-layer async-scsi-scanning, the link state for disconnected port is displayed wrong. Additional check for cable presence is considered to display proper link state. Signed-off-by:

With debug kernels, the memory allocated with kmem_cache_alloc might be initialized with the poison values 6b and a5. Use kmem_cache_zalloc instead of kmem_cache_alloc to get zeroed memory and not send invalid requests. Signed-off-by:

Link Down -> Mark all devices missing Previously, the driver took no action on a Link Down, and waited for the I/O on a dead connection to timeout in the firmware before marking the DDB missing. Link Up -> Mark all devices online F/W will do auto login to all the devices only once. After that its the responsibility of the driver to relogin to devices whenever there is : * Any sort of connection failure or * KATO expires indicating target has logged out or * I/O times out etc. Signed-off-by: -

If cxgb3i_pdu_init() fails, then it appears that cxgb3i_iscsi_init() will not be cleaned up, leading to the iscsi transport being left registered. Fix this by adding a call to cxgb3i_iscsi_cleanup() on the error path. Signed-off-by:

The scsi/scsi.h header is normally provided by the libc (and was not exported by the kernel since 2.6.24) and has been until it was re-exported with 2.6.31. The kernel version is not userspace clean and does not appear to provide anything useable in userland over the (e)glibc version. Signed-off-by:

In the original code we dereferenced "pm8001_dev" before checking if it was null. This patch moves the dereference inside the condition. This was found by a static checker (smatch). I looked, but I couldn't tell if "pm8001_dev" dev was ever actually null. The approach in this patch seemed like the safest response. Signed-off-by:

If a command times out resulting in EH getting invoked, we wait for the aborted commands to come back after sending the abort. Shorten the amount of time we wait for these responses, to ensure we don't get stuck in EH for several minutes. Signed-off-by:

Commands which are completed by the VIOS are placed on a CRQ in kernel memory for the ibmvfc driver to process. Each CRQ entry is 16 bytes. The ibmvfc driver reads the first 8 bytes to check if the entry is valid, then reads the next 8 bytes to get the handle, which is a pointer the completed command. This fixes an issue seen on Power 7 where the processor reordered the loads from memory, resulting in processing command completion with a stale handle. This could result in command timeouts, and also early completion of commands. Signed-off-by:

This patch fixes sdev_rw_attr() macro for scsi device sysfs entries. It seems there is no such function snscanf in the current linux kernel, so it fails to compile scsi driver when someone try to add a new rw entry. This has been unfixed for a long time probably because current scsi device has no rw entries. # grep snscanf . -rn ./drivers/scsi/scsi_sysfs.c:489: snscanf (buf, 20, format_string, &sdev->field); \ Signed-off-by:
