commit 78cbccd3bd68 ("aacraid: Fix for KDUMP driver hang")
caused a problem on older controllers which do not support MSI-x (namely
ASR3405,ASR3805). This patch conditionalizes the previous patch to
controllers which support MSI-x

Pull SCSI fix from James Bottomley:
"A single fix this time: a fix for a virtqueue removal bug which only
appears to affect S390, but which results in the queue hanging forever
thus causing the machine to fail shutdown"

The firmware or device, possibly under a heavy I/O load, can return on a
partial unaligned boundary. Scsi-ml expects these requests to be
completed on an alignment boundary. Scsi-ml blindly requeues the I/O
without checking the alignment boundary of the I/O request for the
remaining bytes. This leads to errors, since devices cannot perform
non-aligned read/write operations.
This patch fixes the issue in the driver. It aligns unaligned
completions of FS requests, by truncating them to the nearest alignment
boundary.

In the case of a graceful set of detaches, where the virtio-scsi-ccw
disk is removed from the guest prior to the controller, the guest
behaves quite normally. Specifically, the detach gets us into
sd_sync_cache to issue a Synchronize Cache(10) command, which
immediately fails (and is retried a couple of times) because the device
has been removed. Later, the removal of the controller sees two CRWs
presented, but there's no further indication of the removal from the
guest viewpoint.
[ 17.217458] sd 0:0:0:0: [sda] Synchronizing SCSI cache
[ 17.219257] sd 0:0:0:0: [sda] Synchronize Cache(10) failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
[ 21.449400] crw_info : CRW reports slct=0, oflw=0, chn=1, rsc=3, anc=0, erc=4, rsid=2
[ 21.449406] crw_info : CRW reports slct=0, oflw=0, chn=0, rsc=3, anc=0, erc=4, rsid=0
However, on s390, the SCSI disks can be removed "by surprise" when an
entire controller (host) is removed and all associated disks are removed
via the loop in scsi_forget_host. The same call to sd_sync_cache is
made, but because the controller has already been removed, the
Synchronize Cache(10) command is neither issued (and then failed) nor
rejected.
That the I/O isn't returned means the guest cannot have other devices
added nor removed, and other tasks (such as shutdown or reboot) issued
by the guest will not complete either. The virtio ring has already been
marked as broken (via virtio_break_device in virtio_ccw_remove), but we
still attempt to queue the command only to have it remain there. The
calling sequence provides a bit of distinction for us:
virtscsi_queuecommand()
-> virtscsi_kick_cmd()
-> virtscsi_add_cmd()
-> virtqueue_add_sgs()
-> virtqueue_add()
if success
return 0
elseif vq->broken or vring_mapping_error()
return -EIO
else
return -ENOSPC
A return of ENOSPC is generally a temporary condition, so returning
"host busy" from virtscsi_queuecommand makes sense here, to have it
redriven in a moment or two. But the EIO return code is more of a
permanent error and so it would be wise to return the I/O itself and
allow the calling thread to finish gracefully. The result is these four
kernel messages in the guest (the fourth one does not occur prior to
this patch):
[ 22.921562] crw_info : CRW reports slct=0, oflw=0, chn=1, rsc=3, anc=0, erc=4, rsid=2
[ 22.921580] crw_info : CRW reports slct=0, oflw=0, chn=0, rsc=3, anc=0, erc=4, rsid=0
[ 22.921978] sd 0:0:0:0: [sda] Synchronizing SCSI cache
[ 22.921993] sd 0:0:0:0: [sda] Synchronize Cache(10) failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
I opted to fill in the same response data that is returned from the more
graceful device detach, where the disk device is removed prior to the
controller device.

mpt3sas has a firmware failure where it can only handle one pass through
ATA command at a time. If another comes in, contrary to the SAT
standard, it will hang until the first one completes (causing long
commands like secure erase to timeout). The original fix was to block
the device when an ATA command came in, but this caused a regression
with

scsi: srp_transport: Move queuecommand() wait code to SCSI core
So fix the original fix of the secure erase timeout by properly
returning SAM_STAT_BUSY like the SAT recommends. The original patch
also had a concurrency problem since scsih_qcmd is lockless at that
point (this is fixed by using atomic bitops to set and test the flag).

Currently, dma_alloc_coherent is being called with a GFP_KERNEL
flag which allows it to sleep in an interrupt context, need to
change to GFP_ATOMIC.

Current code incorrectly calculates the max transfer length, since
it is assuming a 4k page table, but ppc64 all run on 64k page tables.

Pull block fixes from Jens Axboe:
- the virtio_blk stack DMA corruption fix from Christoph, fixing and
issue with VMAP stacks.
- O_DIRECT blkbits calculation fix from Chandan.
- discard regression fix from Christoph.
- queue init error handling fixes for nbd and virtio_blk, from Omar and
Jeff.
- two small nvme fixes, from Christoph and Guilherme.
- rename of blk_queue_zone_size and bdev_zone_size to _sectors instead,
to more closely follow what we do in other places in the block layer.
This interface is new for this series, so let's get the naming right
before releasing a kernel with this feature. From Damien.
* 'for-linus' of git://git.kernel.dk/linux-block:
block: don't try to discard from __blkdev_issue_zeroout
sd: remove __data_len hack for WRITE SAME
nvme: use blk_rq_payload_bytes
scsi: use blk_rq_payload_bytes
block: add blk_rq_payload_bytes
block: Rename blk_queue_zone_size and bdev_zone_size
nvme: apply DELAY_BEFORE_CHK_RDY quirk at probe time too
nvme-rdma: fix nvme_rdma_queue_is_ready
virtio_blk: fix panic in initialization error path
nbd: blk_mq_init_queue returns an error code on failure, not NULL
virtio_blk: avoid DMA to stack for the sense buffer
do_direct_IO: Use inode->i_blkbits to compute block count to be cleaned
|
|
Now that we have the blk_rq_payload_bytes helper available to determine
the actual I/O size we don't need to mess around with __data_len for
WRITE SAME.

Without that we'll pass a wrong payload size in cmd->sdb, which
can lead to hangs with drivers that need the total transfer size.

Pull SCSI fixes from James Bottomley:
"The major fix is the bfa firmware, since the latest 10Gb cards fail
probing with the current firmware.
The rest is a set of minor fixes: one missed Kconfig dependency
causing randconfig failures, a missed error return on an error leg, a
change for how multiqueue waits on a blocked device and a don't reset
while in reset fix"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: bfa: Increase requested firmware version to 3.2.5.1
scsi: snic: Return error code on memory allocation failure
scsi: fnic: Avoid sending reset to firmware when another reset is in progress
scsi: qedi: fix build, depends on UIO
scsi: scsi-mq: Wait for .queue_rq() if necessary
