Added support in the driver to support EEH and PCIe Advanced Error Recovery. This involves adding new pci_error_handler interface for recovering the controller from PCI Bus errors, such as SERR and PERR. Some tools are available for simulating PCI errors in order to validate this interface: http://www.kernel.org/pub/linux/utils/pci/aer-injectSigned-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:

sd always tries to submit a READ_CAPACITY(16) CDB, regardless whether the host actually supports it. queuecommand() will then return DID_ABORT, which is not qualified enough to detect the true cause here. So better check in sd_try_rc16 first if the cdblen is supported. Signed-off-by:

When bnx2/cnic/bnx2i drivers are loaded in certain order, bnx2i will will not initialize the device correctly because 'hba->cnic' will be NULL when bnx2i_start() is called from register_device() context. Under this condition 'ifdown' and 'ifup' of associated network interface is required to bring iscsi adapter state to ready state so that it will accept iscsi connection setup within the chip Initializing 'hba->cnic' before calling register_device() will fix this issue Signed-off-by:

The return code FAST_IO_FAIL from fc_block_scsi_eh indicates that the pending I/O requests have been terminated as a result of the fast_io_fail_tmo. Pass this return code back to the scsi eh to stop the scsi eh in this case. Signed-off-by:

Christof Schmitt authored
If the scsi eh is running and then a FC LLD calls fc_remote_port_delete, the SCSI commands sent from the eh will fail. To prevent this, a FC LLD can call fc_block_scsi_eh from the eh callback, blocking the eh thread until the dev_loss_tmo fires or the remote port is available again. If (e.g. for a multipathing setup) the dev_loss_tmo is set to a very large value, thus preventing the scsi device removal , the scsi eh can block for a long time. For multipathing, the fast_io_fail_tmo is then set to a low value to detect path problems sooner. This patch introduces a new return code FAST_IO_FAIL. The function fc_block_scsi_eh now returns FAST_IO_FAIL when the fast_io_fail_tmo fires. This indicates that the LLD terminated all pending I/O requests and there are no more pending SCSI commands for the scsi eh to wait for. This return code can be passed back to the scsi eh to stop the escalation and finish the recovery process for this device. Signed-off-by:
