The following commit:

  75925e1a ("perf/x86: Optimize stack walk user accesses")

... switched from copy_from_user_nmi() to __copy_from_user_nmi() with a manual
access_ok() check.

Unfortunately, copy_from_user_nmi() does an explicit check against TASK_SIZE,
whereas the access_ok() uses whatever the current address limit of the task is.

We are getting NMIs when __probe_kernel_read() has switched to KERNEL_DS, and
then see vmalloc faults when we access what looks like pointers into vmalloc
space:

The token table passed into match_token() must be null-terminated, which
it currently is not in the perf's address filter string parser, as caught
by Vince's perf_fuzzer and KASAN.

It doesn't blow up otherwise because of the alignment padding of the table
to the next element in the .rodata, which is luck.

Fixing by adding a null-terminator to the token table.

Vince Weaver reported the following bug when KASAN is enabled:

 [  205.748005] BUG: KASAN: slab-out-of-bounds in snb_uncore_imc_event_del+0x6c/0xa0 at addr ffff8800caa43768
 [  205.758324] Read of size 8 by task perf_fuzzer/6618

It's caused by accessing box->event_list.

For client IMC, there are no generic counters. It defines its own fixed
free running counters. So event_list and n_events are unused.

They can be removed safely, which fixes the bug.

( There's still the separate question of how uninitialized state snuck into
  this data structure - but that's a separate fix. )

Commit:

  db4a8356 ("perf/core: Set cgroup in CPU contexts for new cgroup events")

failed to verify that event->cgrp is actually the scheduled cgroup
in a CPU before setting cpuctx->cgrp. This patch fixes that.

Now that there is a different path for scheduled and unscheduled
cgroup, add a warning to catch when cpuctx->cgrp is still set after
the last cgroup event has been unsheduled.

To verify the bug:

  # Create 2 cgroups.
  mkdir /dev/cgroups/devices/g1
  mkdir /dev/cgroups/devices/g2

  # launch a task, bind it to a cpu and move it to g1
  CPU=2
  while :; do : ; done &
  P=$!

  taskset -pc $CPU $P
  echo $P > /dev/cgroups/devices/g1/tasks

  # monitor g2 (it runs no tasks) and observe output
  perf stat -e cycles -I 1000 -C $CPU -G g2

  #           time             counts unit events
     1.000091408          7,579,527      cycles                    g2
     2.000350111      <not counted>      cycles                    g2
     3.000589181      <not counted>      cycles                    g2
     4.000771428      <not counted>      cycles                    g2

  # note first line that displays that a task run in g2, despite
  # g2 having no tasks. This is because cpuctx->cgrp was wrongly
  # set when context of new event was installed.
  # After applying the fix we obtain the right output:

  perf stat -e cycles -I 1000 -C $CPU -G g2
  #           time             counts unit events

Since commit b45f64d1 ("mlxsw: spectrum_router: Use FIB notifications
instead of switchdev calls") we reflect to the device the entire FIB
table and not only FIBs that point to netdevs created by the driver.

During module removal, FIBs of the second type are removed following
NETDEV_UNREGISTER events sent. The other FIBs are still present in both
the driver's cache and the device's table.

Fix this by iterating over all the FIB tables in the device and flush
them. There's no need to take locks, as we're the only writer.

Commit 52f95bbf ("stmmac: fix adjust link call in case of a switch
is attached") added some logic to avoid polling the fixed PHY and
therefore invoking the adjust_link callback more than once, since this
is a fixed PHY and link events won't be generated.

This works fine the first time, because we start with phydev->irq =
PHY_POLL, so we call adjust_link, then we set phydev->irq =
PHY_IGNORE_INTERRUPT and we stop polling the PHY.

Now, if we called ndo_close(), which calls both phy_stop() and does an
explicit netif_carrier_off(), we end up with a link down. Upon calling
ndo_open() again, despite starting the PHY state machine, we have
PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the
link is permanently down.

Now when users shutdown a sock with SEND_SHUTDOWN in sctp, even if
this sock has no connection (assoc), sk state would be changed to
SCTP_SS_CLOSING, which is not as we expect.

Besides, after that if users try to listen on this sock, kernel
could even panic when it dereference sctp_sk(sk)->bind_hash in
sctp_inet_listen, as bind_hash is null when sock has no assoc.

This patch is to move sk state change after checking sk assocs
is not empty, and also merge these two if() conditions and reduce
indent level.

bnx2: Wait for in-flight DMA to complete at probe stage

This is v2 post.

In commit 3e1be7ad ("bnx2: Reset device during driver initialization"),
firmware requesting code was moved from open stage to probe stage.
The reason is in kdump kernel hardware iommu need device be reset in
driver probe stage, otherwise those in-flight DMA from 1st kernel
will continue going and look up into the newly created io-page tables.
However bnx2 chip resetting involves firmware requesting issue, that
need be done in open stage.

Michale Chan suggested we can just wait for the old in-flight DMA to
complete at probe stage, then though without device resetting, we
don't need to worry the old in-flight DMA could continue looking up
the newly created io-page tables.

v1->v2:
    Michael suggested to wait for the in-flight DMA to complete at probe
    stage. So give up the old method of trying to reset chip at probe
    stage, take the new way accordingly.

In commit 022d00ee ("ASoC: lpass-platform: Fix broken pcm data

the dma channel information not being initialized if there was no
alloc_dma_channel() helper function.

Before that, the DMA channel number was implicitly initialized to zero
because the backing store was allocated with devm_kzalloc().  When the
init code was rewritten, that implicit initialization was lost, and gcc
rightfully complains about an uninitialized variable being used.

This reverts commit bfd8d3f2.

It turns out that this flushes things much too aggressiverly, and causes
lines to break up when the system logger races with new continuation
lines being printed.

There's a pending patch to make printk() flushing much more
straightforward, but it's too invasive for 4.9, so in the meantime let's
just not make the system message logging flush continuation lines.
They'll be flushed by the final newline anyway.

This is a static checker warning, not something I'm desperately
concerned about.  But snprintf() returns the number of bytes that
would have been copied if there were space.  We really care about the
number of bytes that actually were copied so we should use scnprintf()
instead.

It probably won't overrun, and in that case we may as well just use
sprintf() but these sorts of things make static checkers and code
reviewers happier.

The peer_addr member of intel_ntb_dev is not set, therefore when
acquiring ntb_peer_db and ntb_peer_spad we only get the offset rather
than the actual physical address. Adding fix to correct that.

schedule_timeout_* takes a timeout in jiffies but the code currently is
passing in a constant which makes this timeout HZ dependent, so pass it
through msecs_to_jiffies() to fix this up.

efx_copy_channel() doesn't correctly clear the napi_hash related state.
This means that when napi_hash_add is called for that channel nothing is
done, and we are left with a copy of the napi_hash_node from the old
channel. When we later call napi_hash_del() on this channel we have a
stale napi_hash_node.

Corruption is only seen when there are multiple entries in one of the
napi_hash lists. This is made more likely by having a very large number
of channels. Testing was carried out with 512 channels - 32 channels on
each of 16 ports.

This failure typically appears as protection faults within napi_by_id()
or napi_hash_add(). efx_copy_channel() is only used when tx or rx ring
sizes are changed (ethtool -G).

Merge media fixes from Mauro Carvalho Chehab:
 "This contains two patches fixing problems with my patch series meant
  to make USB drivers to work again after the DMA on stack changes.

  The last patch on this series is actually not related to DMA on stack.
  It solves a longstanding bug affecting module unload, causing
  module_put() to be called twice. It was reported by the user who
  reported and tested the issues with the gp8psk driver with the DMA
  fixup patches. As we're late at -rc cycle, maybe you prefer to not
  apply it right now. If this is the case, I'll add to the pile of
  patches for 4.10.

  Exceptionally this time, I'm sending the patches via e-mail, because
  I'm on another trip, and won't be able to use the usual procedure
  until Monday. Also, it is only three patches, and you followed already
  the discussions about the first one"
