#1167473 — [PATCH 3.19.y-ckt 002/146] ozwpan: divide-by-zero leading to panic

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Jason A. Donenfeld" <Jason@zx2c4.com>

commit 04bf464a5dfd9ade0dda918e44366c2c61fce80b upstream.

A network supplied parameter was not checked before division, leading to
a divide-by-zero. Since this happens in the softirq path, it leads to a
crash. A PoC follows below, which requires the ozprotocol.h file from
this module.

#1167474 — [PATCH 3.19.y-ckt 005/146] x86: kvm: Revert "remove sched notifier for cross-cpu migrations"

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marcelo Tosatti <mtosatti@redhat.com>

commit 0a4e6be9ca17c54817cf814b4b5aa60478c6df27 upstream.

The following point:

    2. per-CPU pvclock time info is updated if the
       underlying CPU changes.

Is not true anymore since "KVM: x86: update pvclock area conditionally,
on cpu migration".

Add task migration notification back.

Problem noticed by Andy Lutomirski.

#1167475 — [PATCH 3.19.y-ckt 026/146] iio:st_sensors: Fix oops when probing SPI devices

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alban Bedel <alban.bedel@avionic-design.de>

commit 8e71c04f863a1754f21b27fb8ecb773d680a0a80 upstream.

In SPI mode the transfer buffer is locked with a mutex. However this
mutex is only initilized after the probe, but some transfer needs to
be done in the probe.

To fix this bug we move the mutex initialization at the beginning of
the device probe.

#1167476 — [PATCH 3.19.y-ckt 014/146] jhash: Update jhash_[321]words functions to use correct initval

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexander Duyck <alexander.h.duyck@redhat.com>

commit 2e7056c433216f406b90a003aa0ba42e19d3bdcf upstream.

Looking over the implementation for jhash2 and comparing it to jhash_3words
I realized that the two hashes were in fact very different.  Doing a bit of
digging led me to "The new jhash implementation" in which lookup2 was
supposed to have been replaced with lookup3.

In reviewing the patch I noticed that jhash2 had originally initialized a
and b to JHASH_GOLDENRATIO and c to initval, but after the patch a, b, and
c were initialized to initval + (length << 2) + JHASH_INITVAL.  However the
changes in jhash_3words simply replaced the initialization of a and b with
JHASH_INITVAL.

This change corrects what I believe was an oversight so that a, b, and c in
jhash_3words all have the same value added consisting of initval + (length
<< 2) + JHASH_INITVAL so that jhash2 and jhash_3words will now produce the
same hash result given the same inputs.

it is sent only at the end of a dump.

Libraries like libnl will wait forever for NLMSG_DONE.

#1167479 — [PATCH 3.19.y-ckt 013/146] nfsd: fix nsfd startup race triggering BUG_ON

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Giuseppe Cantavenera <giuseppe.cantavenera.ext@nokia.com>

commit bb7ffbf29e76b89a86ca4c3ee0d4690641f2f772 upstream.

nfsd triggered a BUG_ON in net_generic(...) when rpc_pipefs_event(...)
in fs/nfsd/nfs4recover.c was called before assigning ntfsd_net_id.
The following was observed on a MIPS 32-core processor:
kernel: Call Trace:

Fixed this behaviour by calling register_pernet_subsys(&nfsd_net_ops) before
registering rpc_pipefs_event(...) with the notifier chain.

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jacob Pan <jacob.jun.pan@linux.intel.com>

commit d0716b0ea4ce11a13477163c14b26e180922ba51 upstream.

Commit 65de7654d39c70c2b ("iio: iio: Fix iio_channel_read return if
channel havn't info") added a check for valid info masks.

This patch adds missing channel info masks for all ADC channels.
Otherwise, iio_read_channel_raw() would return -EINVAL when called
by consumer drivers.

Note that the change of _processed to _raw actually fixes an ABI abuse
in the original driver where it was used to avoid some special handling
rather than because it was correct.

#1167485 — [PATCH 3.19.y-ckt 010/146] usb: dwc2: hcd: use new USB_RESUME_TIMEOUT

3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felipe Balbi <balbi@ti.com>

commit 74bd7b69801819707713b88e9d0bc074efa2f5e7 upstream.

Make sure we're using the new macro, so our
resume signaling will always pass certification.
