FC and iSCSI class set SCSI devices to transport-offline state after fast_io_fail/replacement_timeout has fired, but after relogin, function scsi_internal_device_unblock() is not setting scsi device state to running. Due to this the devices even after being relogged in remain offline. Signed-off-by:

Fix warning:- drivers/scsi/qla4xxx/ql4_nx.c:1867:2: warning: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘uint32_t’ [-Wformat] Signed-off-by:

In qla4xxx_ep_connect(), qla_ep->dst_addr and dst_addr are type struct sockaddr. We are copying sizeof(struct sockaddr_in6) bytes from dst_addr to qla_ep->dst_addr which is 12 bytes larger. This will cause memory corruption. So we change qla_ep->dst_addr to struct sockaddr_storage which is of 128 byte, large enough to hold sizeof(struct sockaddr_in6). Signed-off-by:

It turns out Smart Array logical drives do not support target reset and when the target reset fails, the logical drive will be taken off line. Symptoms look like this: hpsa 0000:03:00.0: Abort request on C1:B0:T0:L0 hpsa 0000:03:00.0: resetting device 1:0:0:0 hpsa 0000:03:00.0: cp ffff880037c56000 is reported invalid (probably means target device no longer present) hpsa 0000:03:00.0: resetting device failed. sd 1:0:0:0: Device offlined - not ready after error recovery sd 1:0:0:0: rejecting I/O to offline device EXT3-fs error (device sdb1): read_block_bitmap: LUN reset is supported though, and is what we should be using. Target reset is also disruptive in shared SAS situations, for example, an external MSA1210m which does support target reset attached to Smart Arrays in multiple hosts -- a target reset from one host is disruptive to other hosts as all LUNs on the target will be reset and will abort all outstanding i/os back to all the attached hosts. So we should use LUN reset, not target reset. Tested this with Smart Array logical drives and with tape drives. Not sure how this bug survived since 2009, except it must be very rare for a Smart Array to require more than 30s to complete a request. Signed-off-by:
