After improving setsockopt() coverage in trinity, I started triggering
vmalloc failures pretty reliably from this code path:
warn_alloc_failed+0xe9/0x140
__vmalloc_node_range+0x1be/0x270
vzalloc+0x4b/0x50
__do_replace+0x52/0x260 [ip_tables]
do_ipt_set_ctl+0x15d/0x1d0 [ip_tables]
nf_setsockopt+0x65/0x90
ip_setsockopt+0x61/0xa0
raw_setsockopt+0x16/0x60
sock_common_setsockopt+0x14/0x20
SyS_setsockopt+0x71/0xd0
It turns out we don't validate that the num_counters field in the
struct we pass in from userspace is initialized.
The same problem also exists in ebtables, arptables, ipv6, and the
compat variants.

nfnetlink_{log,queue}_init() register the netlink callback nf*_rcv_nl_event
before registering the pernet_subsys, but the callback relies on data
structures allocated by pernet init functions.
When nfnetlink_{log,queue} is loaded, if a netlink message is received after
the netlink callback is registered but before the pernet_subsys is registered,
the kernel will panic in the sequence
nfulnl_rcv_nl_event
nfnl_log_pernet
net_generic
BUG_ON(id == 0) where id is nfnl_log_net_id.
The panic can be easily reproduced in 4.0.3 by:
while true ;do modprobe nfnetlink_log ; rmmod nfnetlink_log ; done &
while true ;do ip netns add dummy ; ip netns del dummy ; done &
This patch moves register_pernet_subsys to earlier in nfnetlink_log_init.
Notice that the BUG_ON hit in 4.0.3 was recently removed in 2591ffd308
["netns: remove BUG_ONs from net_generic()"].

We've got reports that ALC3226 (a Dell variant of ALC292) gives click
noises at transition from D3 to D0 when the widget power-saving is
enabled. Further debugging session showed that avoiding it isn't
trivial, unfortunately, since paths are basically activated
dynamically while the pins have been already enabled.
This patch disables the widget power-saving for such codecs.

The widget (node) power-saves restore the widget states at each
transition from D3 to D0 on each node. This was added in the commit
[d545a57c5f84:ALSA: hda - Sync node attributes at resume from widget
power saving]. However, the test was rater false-positive; this
wasn't needed for any codecs.
Since the resync may take significant number of additional verbs to be
executed, it's better to reduce it. Let's disable it for now again.

If while setting a block group read-only we end up allocating a system
chunk, through check_system_chunk(), we were not doing it while holding
the chunk mutex which is a problem if a concurrent chunk allocation is
happening, through do_chunk_alloc(), as it means both block groups can
end up using the same logical addresses and physical regions in the
device(s). So make sure we hold the chunk mutex.

btrfs_check_shared() is leaking a return value of '1' from
find_parent_nodes(). As a result, callers (in this case, extent_fiemap())
are told extents are shared when they are not. This in turn broke fiemap on
btrfs for kernels v3.18 and up.
The fix is simple - we just have to clear 'ret' after we are done processing
the results of find_parent_nodes().
It wasn't clear to me at first what was happening with return values in
btrfs_check_shared() and find_parent_nodes() - thanks to Josef for the help
on irc. I added documentation to both functions to make things more clear
for the next hacker who might come across them.
If we could queue this up for -stable too that would be great.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes
Summary:
- Use generic function to get buffer count instead of specific one.
In case of Exynos DRM, There was a special case which decides pixel
format of a given buffer according to planer types, which is NV12M and NV12.
However, NV12M doesn't exist in drm fourcc so it removes
exynos_drm_format_num_buffers() specific to Exynos DRM and use a generic function,
drm_format_num_planes() instead.
- Allow mixer driver to support NV21 format for Video processor.
This format was already supported but we just missed DRM_FORMAT_NV21 case
so this patch considers the case so that Mixer driver can handle it correctly.
- Add regression fix and some code cleanups.

After sending the new data packets to probe (step 2), F-RTO may
incorrectly send more probes if the next ACK advances SND_UNA and
does not sack new packet. However F-RTO RFC 5682 probes at most
once. This bug may cause sender to always send new data instead of
repairing holes, inducing longer HoL blocking on the receiver for
the application.

Undo based on TCP timestamps should only happen on ACKs that advance
SND_UNA, according to the Eifel algorithm in RFC 3522:
Section 3.2:
(4) If the value of the Timestamp Echo Reply field of the
acceptable ACK's Timestamps option is smaller than the
value of RetransmitTS, then proceed to step (5),
Section Terminology:
We use the term 'acceptable ACK' as defined in [RFC793]. That is an
ACK that acknowledges previously unacknowledged data.
This is because upon receiving an out-of-order packet, the receiver
returns the last timestamp that advances RCV_NXT, not the current
timestamp of the packet in the DUPACK. Without checking the flag,
the DUPACK will cause tcp_packet_delayed() to return true and
tcp_try_undo_loss() will revert cwnd reduction.
Note that we check the condition in CA_Recovery already by only
calling tcp_try_undo_partial() if FLAG_SND_UNA_ADVANCED is set or
tcp_try_undo_recovery() if snd_una crosses high_seq.

A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different
VCPU than it is bound to. This can result in a race between
handle_percpu_irq() and removing the action in __free_irq() because
handle_percpu_irq() does not take desc->lock. The interrupt handler
sees a NULL action and oopses.
Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER).

Also, let's limit the minimum timebase to 16 steps, to allow a sane
range of duty cycle steps.

mixer_regs_dump() was called in mixer_run(), which was called
under the register spinlock in mixer_graph_buffer() and
vp_video_buffer().
This would trigger a sysmmu pagefault with drm.debug=0xff because
of the large delay caused by the register dumping.
To keep consistency also move register dumping out of mixer_stop(),
which is the counterpart to mixer_run().

Disabling the CONFIG_DRM_EXYNOS_FIMD (e.g. by enabling of CONFIG_FB_S3C)
leads to build error:
drivers/built-in.o: In function `exynos_dp_dpms':
binder.c:(.text+0xd6a840): undefined reference to `fimd_dp_clock_enable'
binder.c:(.text+0xd6ab54): undefined reference to `fimd_dp_clock_enable'

Move the defines for the pixelformats that the mixer supports out
of mixer_graph_buffer() to the top of the source.
Then select the mixer pixelformat (pf) in mixer_graph_buffer() based on
the plane's pf (and not bpp).
Also add handling of RGB565 and XRGB1555 to the switch statement and
exit early if the plane has an unsupported pf.
Partially based on 'drm/exynos: enable/disable blend based on pixel
format' by Gustavo Padovan <gustavo.padovan@collabora.co.uk>.
v2: Use the shorter MXR_FORMAT as prefix.
v3: Re-add ARGB8888 because of compatibility reasons
(suggested by Joonyoung Shim).

The video processor (VP) supports four formats: NV12, NV21 and its
tiled variants. All these formats are bi-planar, so the buffer
count in vp_video_buffer() is always 2.
Also properly exit if we're called with an invalid (non-VP) pixelformat.

Previously we were ignoring the buffer offsets that are
passed through the addfb2 ioctl. This didn't cause any
major issues, since for uni-planar formats (like XRGB8888)
userspace would most of the time just use offsets[0]=0.
However with NV12 offsets[1] is very likely non-zero.
So properly apply the offsets to our dma addresses.

The previous code had some special case handling for the buffer
count in exynos_drm_format_num_buffers().
This code was incorrect though, since this special case doesn't
exist for DRM. It stemmed from the existence of the special NV12M
V4L2 format. NV12 is a bi-planar format (separate planes for luma
and chroma) and V4L2 differentiates between a NV12 buffer where
luma and chroma is contiguous in memory (so no data between
luma/chroma), and a NV12 buffer where luma and chroma have two
explicit memory locations (which is then called NV12M).
This distinction doesn't exist for DRM. A bi-planar format always
explicitly comes with the information about its two planes (even
if these planes should be contiguous).

Currently in snd_pcm_update_hw_ptr0 during interrupt,
we consider there were double acknowledged interrupts when:
1. HW reported pointer is smaller than expected, and
2. Time from last update time (hdelta) is over half a buffer time.
However, when HW reported pointer is only a few bytes smaller than
expected, and when hdelta is just a little larger than half a buffer time
(e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged.
The condition #2 uses jiffies, but jiffies is not high resolution
since it is integer. We should consider jiffies inaccuracy.

block plug callback could sleep, so we introduce a parameter
'from_schedule' and corresponding drivers can use it to destinguish a
schedule plug flush or a plug finish. Unfortunately io_schedule_out
still uses blk_flush_plug(). This causes below output (Note, I added a
might_sleep() in raid1_unplug to make it trigger faster, but the whole
thing doesn't matter if I add might_sleep). In raid1/10, this can cause
deadlock.
This patch makes io_schedule_out always uses blk_schedule_flush_plug.
This should only impact drivers (as far as I know, raid 1/10) which are
sensitive to the 'from_schedule' parameter.

By inspection, this appears to be a typo. The gating comparison
involves vxlan->dev rather than dev. In fact, dev is the iterator in
the preceding loop above but it is actually constant in the 2nd loop.
Use of dev seems to be a bad cut-n-paste from the prior call to
unregister_netdevice_queue. Change dev to vxlan->dev, since that is
what is actually being checked.

256 bytes per sector support has been broken since 2.6.X,
and no-one stepped up to fix this.
So disable support for it.
