Btrfs: fix btrfs_decompress_buf2page()
If btrfs_decompress_buf2page() is handed a bio with its page in the
middle of the working buffer, then we adjust the offset into the working
buffer. After we copy into the bio, we advance the iterator by the
number of bytes we copied. Then, we have some logic to handle the case
of discontiguous pages and adjust the offset into the working buffer
again. However, if we didn't advance the bio to a new page, we may enter
this case in error, essentially repeating the adjustment that we already
made when we entered the function. The end result is bogus data in the
bio.
Previously, we only checked for this case when we advanced to a new
page, but the conversion to bio iterators changed that. This restores
the old, correct behavior.
A case I saw when testing with zlib was:
buf_start = 42769
total_out = 46865
working_bytes = total_out - buf_start = 4096
start_byte = 45056
The condition (total_out > start_byte && buf_start < start_byte) is
true, so we adjust the offset:
buf_offset = start_byte - buf_start = 2287
working_bytes -= buf_offset = 1809
current_buf_start = buf_start = 42769
Then, we copy
bytes = min(bvec.bv_len, PAGE_SIZE - buf_offset, working_bytes) = 1809
buf_offset += bytes = 4096
working_bytes -= bytes = 0
current_buf_start += bytes = 44578
After bio_advance(), we are still in the same page, so start_byte is the
same. Then, we check (total_out > start_byte && current_buf_start < start_byte),
which is true! So, we adjust the values again:
buf_offset = start_byte - buf_start = 2287
working_bytes = total_out - start_byte = 1809
current_buf_start = buf_start + buf_offset = 45056
But note that working_bytes was already zero before this, so we should
have stopped copying.

x86/tsc: Avoid the large time jump when sanitizing TSC ADJUST
Olof reported that on a machine which has a BIOS wreckaged TSC the
timestamps in dmesg are making a large jump because the TSC value is
jumping forward after resetting the TSC ADJUST register to a sane value.
This can be avoided by calling the TSC ADJUST saniziting function before
initializing the per cpu sched clock machinery. That takes the offset into
account and avoid the time jump.
What cannot be avoided is that the 'Firmware Bug' warnings on the secondary
CPUs are printed with the large time offsets because it would be too much
effort and ugly hackery to print those warnings into a buffer and emit them
after the adjustemt on the starting CPUs. It's a firmware bug and should be
fixed in firmware. The weird timestamps are collateral damage and just
illustrate the sillyness of the BIOS folks:

tick/nohz: Fix possible missing clock reprog after tick soft restart
ts->next_tick keeps track of the next tick deadline in order to optimize
clock programmation on irq exit and avoid redundant clock device writes.
Now if ts->next_tick missed an update, we may spuriously miss a clock
reprog later as the nohz code is fooled by an obsolete next_tick value.
This is what happens here on a specific path: when we observe an
expired timer from the nohz update code on irq exit, we perform a soft
tick restart which simply fires the closest possible tick without
actually exiting the nohz mode and restoring a periodic state. But we
forget to update ts->next_tick accordingly.
As a result, after the next tick resulting from such soft tick restart,
the nohz code sees a stale value on ts->next_tick which doesn't match
the clock deadline that just expired. If that obsolete ts->next_tick
value happens to collide with the actual next tick deadline to be
scheduled, we may spuriously bypass the clock reprogramming. In the
worst case, the tick may never fire again.
Fix this with a ts->next_tick reset on soft tick restart.

Rather than relying on req being NULL (or ERR_PTR) for all cases where
we don't want to trace or should not trace,
simply check retval which is unconditionally initialized with -EIO != 0
and it can only become 0 on successful retval = zfcp_fsf_req_send(req).
With that we can also remove the then again unnecessary unconditional
initialization of req which was introduced with that earlier commit.

call xenbus_dev_fatal() to ensure that the xenbus device is set to the

Pull SCSI target fixes from Nicholas Bellinger:
"This target series for v4.10 contains fixes which address a few
long-standing bugs that DATERA's QA + automation teams have uncovered
while putting v4.1.y target code into production usage.
We've been running the top three in our nightly automated regression
runs for the last two months, and the COMPARE_AND_WRITE fix Mr. Gary
Guo has been manually verifying against a four node ESX cluster this
past week.
Note all of them have CC' stable tags.
Summary:
- Fix a bug with ESX EXTENDED_COPY + SAM_STAT_RESERVATION_CONFLICT
status, where target_core_xcopy.c logic was incorrectly returning
SAM_STAT_CHECK_CONDITION for all non SAM_STAT_GOOD cases (Nixon
Vincent)
- Fix a TMR LUN_RESET hung task bug while other in-flight TMRs are
being aborted, before the new one had been dispatched into tmr_wq
(Rob Millner)
- Fix a long standing double free OOPs, where a dynamically generated
'demo-mode' NodeACL has multiple sessions associated with it, and
the /sys/kernel/config/target/$FABRIC/$WWN/ subsequently disables
demo-mode, but never converts the dynamic ACL into a explicit ACL
(Rob Millner)
- Fix a long standing reference leak with ESX VAAI COMPARE_AND_WRITE
when the second phase WRITE COMMIT command fails, resulting in
CHECK_CONDITION response never being sent and se_cmd->cmd_kref
never reaching zero (Gary Guo)
Beyond these items on v4.1.y we've reproduced, fixed, and run through
our regression test suite using iscsi-target exports, there are two
additional outstanding list items:
- Remove a >= v4.2 RCU conversion BUG_ON that would trigger when
dynamic node NodeACLs where being converted to explicit NodeACLs.
The patch drops the BUG_ON to follow how pre RCU conversion worked
for this special case (Benjamin Estrabaud)
- Add ibmvscsis target_core_fabric_ops->max_data_sg_nent assignment
to match what IBM's Virtual SCSI hypervisor is already enforcing at
transport layer. (Bryant Ly + Steven Royer)"

net: phy: Fix PHY module checks and NULL deref in phy_attach_direct()
The Generic PHY drivers gets assigned after we checked that the current
PHY driver is NULL, so we need to check a few things before we can
safely dereference d->driver. This would be causing a NULL deference to
occur when a system binds to the Generic PHY driver. Update
phy_attach_direct() to do the following:
- grab the driver module reference after we have assigned the Generic
PHY drivers accordingly, and remember we came from the generic PHY
path
- update the error path to clean up the module reference in case the
Generic PHY probe function fails
- split the error path involving phy_detacht() to avoid double free/put
since phy_detach() does all the clean up
- finally, have phy_detach() drop the module reference count before we
call device_release_driver() for the Generic PHY driver case

To my untrained mental entropy detector, the first several bytes of
each read from /dev/hwrng seem to not be very random (i.e. all zero).
When I revert the patch (apply this patch), I get back to what we have
in v4.9, which looks like (much more random appearing):
$ dd if=/dev/hwrng bs=256 count=1 | od -t x1 -A x -v > rng-good.txt
1+0 records in
1+0 records out
256 bytes (256 B) copied, 0.

$ dd if=/dev/hwrng bs=256 count=1 | od -t x1 -A x -v >> rng-good.txt
1+0 records in
