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:

This patch adds a bunch of fixes 1. Reduce sg table size to 64 (SG_MX) instead of default SG_ALL 2. clear task lists on phy down events 3. release all tasks on port deformation 4. release current task for device gone notification 5. Add sata abort handing 6. Add 10ms delay to each port reset (currently done serially and with interrupts disabled) [jejb: whitespace fixes and clean ups plus added description added dummy 94xx_clear_srs_irq function just to prevent the mismatch in the mvs_dispatch structure killing 94xx cards] Signed-off-by:Srinivas <satyasrinivasp@hcl.in> Cc: Andy Yan <ayan@marvell.com> Cc: qswang@marvell.com Cc: jfeng@marvell.com Signed-off-by:

This change is basically a clean up. datadgst_en is an int which comes from the user. I didn't see anything limiting it to 1 and 0 although obviously that's what it's supposed to be. If the user passed in 2 this test would fail. This same if condition is repeated in another function and it uses && there. Signed-off-by:

Print all world wide node names (node, port and fabric) with the same format specifier of "%16.16llx". That makes sure they all print as a 16 character hex string, with lower case letters, no 0x prefix, and without stripping off any leading 0s. Signed-off-by:

Most of the prints of fabric IDs were specified as %6x, which will not print any leading 0s. It's nice to see leading 0s for identifiers like this, which are a fixed length. This patch sets the precision modifier as well, making the specifier %6.6x, which forces the printing of leading 0s. Signed-off-by:

No reason to restrict CDB size to 12 bytes in fcoe, so increased to 16 so that 16 bytes SCSI CDB doesn't fail. Uses common define to set max_cmd_len for fcoe and fnic, fnic is already setting max_cmd_len to 16. sg_readcap -l fails without this fix. Signed-off-by:

The FIP controler state wasn't being reset on a disable. A disable/enable sequence should be treated as a link event. Otherwise, when using disable to mask a time when the link is up but unusable, FCF discovery would attempt to continue and login would jump directly to the non-FIP fallback on enable. Signed-off-by:

FPMA indicates that the Fabric will provide the host's N_Port's MAC address. When sending a FLOGI/FDISC frame and FPMA was negotiated through FIP discovery we still need to provide the MAC descriptor, as per the specification, but the MAC should be zero'd out since the FCF will be providing it in the FLOGI/FDISC ACC. In FC-BB-5 section 7.8.7.4.2 (Fabric login) it states: The MAC address field in the MAC address descriptor of a FIP FLOGI Request operation or a FIP NPIV FDISC Request operation shall contain: a) the proposed MAC address to use as VN_Port MAC address if the ENode is requesting to use SPMA (see table 27); b) all zeroes to indicate no MAC address is proposed if the ENode is requesting to use FPMA (see table 27); or c) the proposed MAC address to use as VN_Port MAC address if the ENode supports both SPMA and FPMA and leaves the decision of which addressing scheme to use to the FCF (i.e., if both the FP and SP bits are set to one, see table 27). This patch fixes case B. This patch also adds debug statements to illustrate whether a FPMA or SPMA MAC is added to a FLOGI/FDISC frame. Signed-off-by:

we added support to set the deleted flag prior to device scan, then clear the flag for responding devices, leaving the deleted flag only set for missing devices. The problem is for internal generated host resets, IO queues are not blocked at scsi mid layer level. IO will be continued sent to driver, and driver will return SCSI_MLQUEUE_HOST_BUSY. The problem is the driver checks for the deleted flag before it checks for the controller being in reset, so there is a window where the driver would be returning DID_NO_CONNECT for responding devices. This occurs during the time between calling _scsih_prep_device_scan, and _scsih_mark_responding_sas_device & _scsih_mark_responding_raid_device. Fix the queuecommand entry point so ioc->shost_recovery flag sanity check is given higher presidence then the device "deleted flag" check. Signed-off-by:
