2012-09-14[SCSI] scsi_lib: Set the device state from transport-offline to runningVikas Chaudhary1-1/+2
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.

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).

2012-09-14[SCSI] scsi: virtio-scsi: Fix address translation failure of HighMem pages ↵Wang Sen1-1/+1
used by sg list When using the commands below to write some data to a virtio-scsi LUN of the QEMU guest(32-bit) with 1G physical memory(qemu -m 1024), the qemu will crash. # sudo mkfs.ext4 /dev/sdb (/dev/sdb is the virtio-scsi LUN.) # sudo mount /dev/sdb /mnt # dd if=/dev/zero of=/mnt/file bs=1M count=1024 In current implementation, sg_set_buf is called to add buffers to sg list which is put into the virtqueue eventually. But if there are some HighMem pages in table->sgl you can not get virtual address by sg_virt. So, sg_virt(sg_elem) may return NULL value. This will cause QEMU exit when virtqueue_map_sg is called in QEMU because an invalid GPA is passed by virtqueue. Two solutions are discussed here: http://lkml.indiana.edu/hypermail/linux/kernel/1207.3/00675.html Finally, value assignment approach was adopted because: Value assignment creates a well-formed scatterlist, because the termination marker in source sg_list has been set in blk_rq_map_sg(). The last entry of the source sg_list is just copied to the the last entry in destination list. Note that, for now, virtio_ring does not care about the form of the scatterlist and simply processes the first out_num + in_num consecutive elements of the sg[] array. I have tested the patch on my workstation. QEMU would not crash any more.

2012-09-14[SCSI] hpsa: Use LUN reset instead of target resetStephen M. Cameron1-1/+1
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: Stephen M.

2012-09-13scsi_netlink: Remove dead and buggy codeEric W. Biederman1-540/+15
The scsi netlink code confuses the netlink port id with a process id, going so far as to read NETLINK_CREDS(skb)->pid instead of the correct NETLINK_CB(skb).pid. Fortunately it does not matter because nothing registers to respond to scsi netlink requests. The only interesting use of the scsi_netlink interface is fc_host_post_vendor_event which sends a netlink multicast message. Since nothing registers to handle scsi netlink messages kill all of the registration logic, while retaining the same error handling behavior preserving the userspace visible behavior and removing all of the confused code that thought a netlink port id was a process id. This was tested with a kernel allyesconfig build which had no problems. Cc: James Bottomley <[email protected]> Cc: James Smart <[email protected]> Signed-off-by: "Eric W.
