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 patch changes the arguments to iscsi_sw_tcp_conn_restore_callbacks, so that it works like the function to set the callbacks and because in upcoming patches we need a iscsi_conn. 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:

Fix a oops in _scsih_sas_device_remove. The driver was attempting to delete a object from the sas_device link list when the object was not present. Added sanity check for sas_device NULL dereference. before deleting sas_device now driver will search device in list then only it will follow device removal. 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:

There are few special cases which needs to be handled deleting old port. CASE1: In topology you need cascaded expanders. Through sysfs just make sure topology is up. Erase the manufacturing image of the cascaded expander and reset the board. In some cases Adapter will receive Exapnder Add event before expander delete. In such a case, driver needs to delete duplicate port before adding new port. CASE2: Enable Device Missing delay of HBA through lsiutils. If expander or end device is hotswapped with different device before DMD timer expires, driver will get device add for new device first and then device deletion event for the original devices will arrive later at DMD timer expires. In this case also driver need to delete duplicate port before adding port for new device. Added new function which will make sure when new port is added, that its not claiming the same phy resources already in use by another port. If it does, then it will delete the other port before adding the new port. Signed-off-by:

While testing the midlevel q_at_head and q_at_tail patch for sg and the block SG_IO ioctl I found it useful to reduce the queuing within the scsi_debug driver. The reason is that the midlevel queue only comes into play when the corresponding LLD queue is full. It is also useful when testing to be confident that your program is the only thing issuing commands to the (virtual) scsi_debug device. The no_uld=1 parameter will stop a scsi_debug virtual disk appearing as /dev/sd* . Changelog: - add max_queue parameter to reduce the number of queued commands the driver will accept. This parameter can be changed after the driver is loaded. - add no_uld parameter that restricts scsi_debug's virtual devices to the sg and bsg drivers - correct stale url Signed-off-by:Douglas Gilbert <dgilbert@interlog.com> Signed-off-by:

Hazard testing uncovered yet another bug in sd. Under heavy reset activity the retry counter might be exhausted and the command will be returned with sense UNIT_ATTENTION/0x29/00 (POWER ON, RESET, OR BUS DEVICE RESET OCCURRED). In those cases we should just increase the retry counter again, retrying one more to clear up this Unit Attention state.

After Host Reset firmware will have new list of device handles for the target. Device handle refresh in driver is part of Rescan topology logic. (See functions like *_search_responding_*). This needs to be done from Host Reset context before making shost_recovery to 0. Currently it is done in Firwmare event context, which may leads IO to a wrong device. Now handler refresh is moved to HBA reset context. Apart from this, Now driver will stop IOs for all device setting deleted flag to 1 at the time of HBA Reset through _scsih_prep_device_scan. It will only unblock devices, if devices has been found as part of RESCAN. This way it will make more safe IO blocking at the time of HBA reset at mpt2sas driver layer. Signed-off-by:
