Things like this will probably keep showing up for other architectures
and other special cases.

I actually thought we already used %lx for this, and that is indeed
_historically_ the case, but we moved to %p when merging the 32-bit and
64-bit cases as a convenient way to get the formatting right (ie
automatically picking "%08lx" vs "%016lx" based on register size).

So just turn this %p into %px.

When the device descriptor is closed, the `substream->runtime` pointer
is freed. But another thread may be in the ioctl handler, case
SNDRV_CTL_IOCTL_PCM_INFO. This case calls snd_pcm_info_user() which
calls snd_pcm_info() which accesses the now freed `substream->runtime`.

The chip family of TILEPro and TILE-Gx was developed by Tilera, which
was eventually acquired by Mellanox.  The tile architecture was added to
the kernel in 2010 and first appeared in 2.6.36.

Now at Mellanox we are developing new chips based on the ARM64
architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and
our customers using tile architecture products are not, as far as we
know, looking to upgrade to newer kernel releases.  In the absence of
someone in the community stepping up to take over maintainership, this
commit marks the architecture as orphaned.

snd_usb_copy_string_desc() returns zero if usb_string() fails.

The snd_usb_copy_string_desc() retrieves the usb string corresponding to
the index number through the usb_string(). The problem is that the
usb_string() returns the length of the string (>= 0) when successful, but
it can also return a negative value about the error case or status of
usb_control_msg().

If iClockSource is '0' as shown below, usb_string() will returns -EINVAL.
This will result in '0' being inserted into buf[-22], and the following
KASAN out-of-bound error message will be output.

AudioControl Interface Descriptor:
  bLength                 8
  bDescriptorType        36
  bDescriptorSubtype     10 (CLOCK_SOURCE)

  Clock Frequency Control (read/write)
  Clock Validity Control (read-only)
  bAssocTerminal          0
  iClockSource            0

To fix it, check usb_string()'return value and bail out.

pull-request: bpf 2017-12-02

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix a compilation warning in xdp redirect tracepoint due to
   missing bpf.h include that pulls in struct bpf_map, from Xie.

2) Limit the maximum number of attachable BPF progs for a given
   perf event as long as uabi is not frozen yet. The hard upper
   limit is now 64 and therefore the same as with BPF multi-prog
   for cgroups. Also add related error checking for the sample
   BPF loader when enabling and attaching to the perf event, from
   Yonghong.

3) Specifically set the RLIMIT_MEMLOCK for the test_verifier_log
   case, so that the test case can always pass and not fail in
   some environments due to too low default limit, also from
   Yonghong.

4) Fix up a missing license header comment for kernel/bpf/offload.c,
   from Jakub.

5) Several fixes for bpftool, among others a crash on incorrect
   arguments when json output is used, error message handling
   fixes on unknown options and proper destruction of json writer
   for some exit cases, all from Quentin.

James Morris reported kernel stack corruption bug [1] while
running the SELinux testsuite, and bisected to a recent
commit bffa72cf ("net: sk_buff rbnode reorg")

We believe this commit is fine, but exposes an older bug.

SELinux code runs from tcp_filter() and might send an ICMP,
expecting IP options to be found in skb->cb[] using regular IPCB placement.

We need to defer TCP mangling of skb->cb[] after tcp_filter() calls.

This patch adds tcp_v4_fill_cb()/tcp_v4_restore_cb() in a very
similar way we added them for IPv6.

In rxrpc_release_sock() there may be no rx->local value to access, so we
can't unconditionally follow it to the rxrpc network namespace information
to poke the connection reapers.

Instead, use the socket's namespace pointer to find the namespace.

This unfixed code causes the following static checker warning:

	net/rxrpc/af_rxrpc.c:898 rxrpc_release_sock()
	error: we previously assumed 'rx->local' could be null (see line 887)

First set of IIO fixes in the 4.15 cycle.

* kernel-doc
  - fix a build error from symbols ending in _ by making them _*
* cpcap
  - Fix wrong handling of platform_get_irq_by_name which can return a
    postive value on success.
* max30102
  - ABI says temperature should bein milli Celsius after scaling. Here it
    was in Celsius.
* meson-saradc:
  - for Meson8/8b the gate clock bit was wrongly selected due to ffs/fls fun.
  - bandgap was not initialized properly on older socs.  Mostly got away
    with this because the bootloader was doing it for us.
  - Meson8/8b don't have some registers in the general regmap config. Give
    them their own ones.
* stm32-lptimer/stm32-adc trigger
  - Fix a link error when optional stm32-lptimer driver isn't built.
* sx9500
  - we recently removed explict handling of ACPI provided gpio interrupts
    as the core i2c acpi code started providing them directly.  Unfortuantely
    there are ACPI tables out there that use GpioIO resources and it doesn't
    know to map those as interrupts.  As such partial revert the removal
    of this handling from the driver.

Remove one extraneous level of indentation on assignment statement.

====================
pull-request: can 2017-12-01

this is a pull for net consisting of nine patches.

The first three patches are by Jimmy Assarsson for the kvaser_usb driver
and add the missing free()s in some error path, a signed/unsigned
comparison and ratelimit the error messages in case of incomplete
messages. Oliver Stäbler's patch for the ti_hecc driver fix the napi
poll function's return value. The return values of the probe function of
the peak_canfd and peak_pci PCI drivers are fixed by Stephane Grosjean's
patch. Two patches by me for the flexcan driver update the
bugs/features/quirks overview table and fix the error state transition
for the VF610 SoC. The two patches by Martin Kelly for the mcba_usb
driver fix a typo and a device disconnect bug.

Please consider pulling the following fixes for v4.15. While it doesn't
fix any regression introduced in the v4.15 merge window, we have a
feature in at24 since linux v4.8 - reading the mac address block from
at24mac series - which turned out to be not working.

This pull request contains changes that fix it together with a patch
that hardens the read and write argument sanitization with
out-of-bounds checks that were missing.

The mss variable tracks the last max segment size sent to the TSO
engine. We do not update the hardware as long as we receive skb:s with
the same value in gso_size.

During a network device down/up cycle (mapped to stmmac_release() and
stmmac_open() callbacks) we issue a reset to the hardware and it
forgets the setting for mss. However we did not zero out our mss
variable so the next transmission of a gso packet happens with an
undefined hardware setting.

This triggers a hang in the TSO engine and eventuelly the netdev
watchdog will bark.
