[SCSI] fix medium error problems with some arrays which can cause data corruption
Our current handling of medium error assumes that data is returned up
to the bad sector. This assumption holds good for all disk devices,
all DIF arrays and most ordinary arrays. However, an LSI array engine
was recently discovered which reports a medium error without returning
any data. This means that when we report good data up to the medium
error, we've reported junk originally in the buffer as good. Worse,
if the read consists of requested data plus a readahead, and the error
occurs in readahead, we'll just strip off the readahead and report
junk up to userspace as good data with no error.
The fix for this is to have the error position computation take into
account the amount of data returned by the driver using the scsi
residual data. Unfortunately, not every driver fills in this data,
but for those who don't, it's set to zero, which means we'll think a
full set of data was transferred and the behaviour will be identical
to the prior behaviour of the code (believe the buffer up to the error
sector). All modern drivers seem to set the residual, so that should
fix up the LSI failure/corruption case.

[SCSI] scsi_dh: propagate SCSI device deletion
Currently, when scsi_dh_activate() returns with an error
(e.g. SCSI_DH_NOSYS) the activate_complete callback is not called and
the error is not propagated to DM mpath.
When a SCSI device attached to a device handler is deleted, userland
processes currently performing I/O on the device will have their I/O
hang forever.
- Set SCSI_DH_NOSYS error when the handler is in the process of being
deleted (e.g. the SCSI device is in a SDEV_CANCEL or SDEV_DEL state).
- Set SCSI_DH_DEV_OFFLINED error when device is in SDEV_OFFLINE state.
- Call the activate_complete callback function directly from
scsi_dh_activate if an error has been set (when either the scsi_dh
internal data has already been deleted or is in the process of being
deleted).
The patch was tested in an iSCSI environment, RDAC H/W handler and
multipath. In the following reproduction process, dd will I/O hang
forever and the only way to release it will be to reboot the machine:
1) Perform I/O on a multipath device:
dd if=/dev/dm-0 of=/dev/zero bs=8k count=
1000000 &
2) Delete all slave SCSI devices contained in the mpath device:
I) In an iSCSI environment, the easiest way to do this is by
stopping iSCSI:
/etc/init.d/iscsi stop
II) Another way to delete the devices is by applying the following
bash scriptlet:
dm_devs=$(ls /sys/block/ | grep dm- | xargs)
for dm_dev in $dm_devs; do
devices=$(ls /sys/block/$dm_dev/slaves)
for device in $devices; do
echo 1 > /sys/block/$device/device/delete
done
done
NOTE: when DM mpath's fail_path uses blk_abort_queue this scsi_dh change
isn't strictly required. However, DM mpath's call to blk_abort_queue
will soon be reverted because it has proven to be unsafe due to a race
(between blk_abort_queue and scsi_request_fn) that can lead to list
corruption. Therefore we cannot rely on blk_abort_queue via fail_path,
but even if we could this scsi_dh change is still preferrable.

[SCSI] zfcp: Redesign of the debug tracing for recovery actions.
The tracing environment of the zfcp LLD has become very bulky and hard
to maintain. Small changes involve a large modification process which
is error-prone and not effective. This patch is the first of a set to
redesign the zfcp tracing to a more straight-forward and easy to

The statistic returned via /sys must be in megabytes, however,
which is what the HBA-API wants. The FCP code needs to accumulate
it in bytes and then divide by 1,000,000 (not 2^20) before it
presented via sysfs.
This affects fcoe.ko only, not fnic. The fnic driver
correctly by accumulating bytes and then converts to megabytes.

This happens when then tearing down the fcoe interface with active I/O.
The back trace shows
dead000000200200 in RAX, i.e., LIST_POISON2, indicating
that the fsp is already being dequeued, which is probably why no complaining
was seen in fc_fcp_destroy() about outstanding fsp not freed, since we dequeue
it in the end of fc_io_compl() before releasing it. The bug is due to the
fact that we have already destroyed lport's scsi_pkt_pool while on-going i/o
is still accessing it through fc_fcp_pkt_release(), like this trace or the
similar code path from scsi-ml to fc_eh_abort, etc. This is fixed by moving
the fc_fcp_destroy() after lport is detached from scsi-ml since fc_fcp_destroy
is supposed to called only once where no lport lock is taken, otherwise the
fc_fcp_pkt_release() would have to grab the lport lock.

[SCSI] bnx2i: Added fix for NOP-Out response panic from unsolicited NOP-In
The patch fixes the following situations where NOP-Out pkt is called for:
- local unsolicited NOP-Out requests (requesting no NOP-In response)
- local NOP-Out responses to unsolicited NOP-In requests
kernel panic is observed due to double session spin_lock requests; one in the
bnx2i_process_nopin_local_cmpl routine in bnx2i_hwi.c and the other in the
iscsi_put_task routine in libiscsi.c
The proposed fix is to export the currently static __iscsi_put_task() routine
and have bnx2i call it directly instead of the iscsi_put_task() routine which
holds the session spin lock.
