acb4b7df48 rocker: move dereference before free
My static checker complains that ofdpa_neigh_del() can sometimes free
"found".   It just makes sense to use it first before deleting it.

6b27c8adf2 mlxsw: spectrum_router: Fix NULL pointer dereference
In case a VLAN device is enslaved to a bridge we shouldn't create a
router interface (RIF) for it when it's configured with an IP address.
This is already handled by the driver for other types of netdevs, such
as physical ports and LAG devices.

If this IP address is then removed and the interface is subsequently
unlinked from the bridge, a NULL pointer dereference can happen, as the
original 802.1d FID was replaced with an rFID which was then deleted.

To reproduce:
$ ip link set dev enp3s0np9 up
$ ip link add name enp3s0np9.111 link enp3s0np9 type vlan id 111
$ ip link set dev enp3s0np9.111 up
$ ip link add name br0 type bridge
$ ip link set dev br0 up
$ ip link set enp3s0np9.111 master br0
$ ip address add dev enp3s0np9.111 192.168.0.1/24
$ ip address del dev enp3s0np9.111 192.168.0.1/24
$ ip link set dev enp3s0np9.111 nomaster

c1a4872ebf net: sched: Fix one possible panic when no destroy callback
When qdisc fail to init, qdisc_create would invoke the destroy callback
to cleanup. But there is no check if the callback exists really. So it
would cause the panic if there is no real destroy callback like the qdisc
codel, fq, and so on.

Take codel as an example following:
When a malicious user constructs one invalid netlink msg, it would cause
codel_init->codel_change->nla_parse_nested failed.
Then kernel would invoke the destroy callback directly but qdisc codel
doesn't define one. It causes one panic as a result.

Now add one the check for destroy to avoid the possible panic.

713a98d90c virtio-net: serialize tx routine during reset
We don't hold any tx lock when trying to disable TX during reset, this
would lead a use after free since ndo_start_xmit() tries to access
the virtqueue which has already been freed. Fix this by using
netif_tx_disable() before freeing the vqs, this could make sure no tx
after vq freeing.

0f17976568 ftrace: Fix regression with module command in stack_trace_filter
When doing the following command:

 # echo ":mod:kvm_intel" > /sys/kernel/tracing/stack_trace_filter

it triggered a crash.

This happened with the clean up of probes. It required all callers to the
regex function (doing ftrace filtering) to have ops->private be a pointer to
a trace_array. But for the stack tracer, that is not the case.

Allow for the ops->private to be NULL, and change the function command
callbacks to handle the trace_array pointer being NULL as well.

c06632ea05 gpio: acpi: Skip _AEI entries without a handler rather then aborting the scan
acpi_walk_resources will stop as soon as the callback passed in returns
an error status. On a x86 tablet I have the first GpioInt in the _AEI
resource list has no handler defined in the DSDT, causing
acpi_walk_resources to abort scanning the rest of the resource list,
which does define valid ACPI GPIO events.

This commit changes the return for not finding a handler from
AE_BAD_PARAMETER to AE_OK so that the rest of the resource list will
get scanned normally in case of missing event handlers.

9ae3b3f52c block: provide bio_uninit() free freeing integrity/task associations
Wen reports significant memory leaks with DIF and O_DIRECT:

"With nvme devive + T10 enabled, On a system it has 256GB and started
logging /proc/meminfo & /proc/slabinfo for every minute and in an hour
it increased by 15968128 kB or ~15+GB.. Approximately 256 MB / minute
leaking.

/proc/meminfo | grep SUnreclaim...

SUnreclaim:      6752128 kB

SUnreclaim:     22307264 kB
SUnreclaim:     22485888 kB
SUnreclaim:     22720256 kB

When testcases with T10 enabled call into __blkdev_direct_IO_simple,
code doesn't free memory allocated by bio_integrity_alloc. The patch
fixes the issue. HTX has been run with +60 hours without failure."

Since __blkdev_direct_IO_simple() allocates the bio on the stack, it
doesn't go through the regular bio free. This means that any ancillary
data allocated with the bio through the stack is not freed. Hence, we
can leak the integrity data associated with the bio, if the device is
using DIF/DIX.

Fix this by providing a bio_uninit() and export it, so that we can use
it to free this data. Note that this is a minimal fix for this issue.
Any current user of bio's that are allocated outside of
bio_alloc_bioset() suffers from this issue, most notably some drivers.
We will fix those in a more comprehensive patch for 4.13. This also
means that the commit marked as being fixed by this isn't the real
culprit, it's just the most obvious one out there.

7204e97685 drm: adv7511_audio: Add .get_dai_id callback to map port number to dai id
ALSA SoC needs to know connected DAI ID for probing. Using
the new audio-card-graph approach, ports/endpoints are used
to describe how the links are connected. Unfortunately, since
ports/endpoints are used as well for video linkages, there
are some issues mixing the port ids to the two (video and
audio) namespaces.

To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.

The will assume that HDMI audio out will be connected to
reg = <2>. This will then be remapped to the ALSA SoC side will
as DAI 0. Allowing the adv7511's hdmi audio support to be used
with the audio-card-graph.

Credit to Kuninori Morimoto who's patch to dw-hdmi-i2s-audio.c
was what this was mostly copy-pasted from.

98faf436ee ASoC: Drop invalid DMI fields when setting card long name from DMI info
Sometimes DMI fields may be invalid and so can't give useful vendor,
product or board info, such as "Type2 - Board Manufacturer" or
"Type1 - TBD by OEM". Including such invalid DMI fileds may create silly
card long name. So this patch creates a black list of invalid strings.
And if a DMI field contains any string in this list, it will be excluded
from the card long name.

ea2b5a6e3a ASoC: rt5645: Add jack detection workaround for GPD Win
GPD Win requires jd_mode=3 and the inverted flag for making the jack
detection working.  Unfortunately, the BIOS doesn't give a nice way to
match with DMI strings, and the only working way so far is to match
with the board vendor/name/version/date to some known patterns.

Hopefully other vendors won't do such a stupid setup, too...

Thanks to Hans de Goede for the DMI matching suggestion.

happening at the controller driver level for PCH controller devices,
where the initialization is performed in a detached work, instead of
calling from the codec driver probe.

84a21dbdef iommu/amd: Fix interrupt remapping when disable guest_mode
Pass-through devices to VM guest can get updated IRQ affinity
information via irq_set_affinity() when not running in guest mode.
Currently, AMD IOMMU driver in GA mode ignores the updated information
if the pass-through device is setup to use vAPIC regardless of guest_mode.
This could cause invalid interrupt remapping.

Also, the guest_mode bit should be set and cleared only when
SVM updates posted-interrupt interrupt remapping information.

fbaf94ee3c ovl: don't set origin on broken lower hardlink
When copying up a file that has multiple hard links we need to break any
association with the origin file.  This makes copy-up be essentially an
atomic replace.

The new file has nothing to do with the old one (except having the same
data and metadata initially), so don't set the overlay.origin attribute.

We can relax this in the future when we are able to index upper object by
origin.

d94815f917 ALSA: hda - Fix endless loop of codec configure
azx_codec_configure() loops over the codecs found on the given
controller via a linked list.  The code used to work in the past, but
in the current version, this may lead to an endless loop when a codec
binding returns an error.

The culprit is that the snd_hda_codec_configure() unregisters the
device upon error, and this eventually deletes the given codec object
from the bus.  Since the list is initialized via list_del_init(), the
next object points to the same device itself.  This behavior change
was introduced at splitting the HD-audio code code, and forgotten to
adapt it here.

For fixing this bug, just use a *_safe() version of list iteration.

f03293d8fc ALSA: Fix forgotten dependency fix for tristate OSS sequencer kconfig
In the commit 3d774d5ef0 ("ALSA: seq: Allow the tristate build of
OSS emulation") we changed CONFIG_SND_SEQUENCER_OSS to tristate, but a
couple of places were forgotten, namely, opl3 and emux Makefile.
These contain the line like
  snd-opl3-synth-$(CONFIG_SND_SEQUENCER_OSS) += opl3_oss.o
and this doesn't work any longer as expected because snd-opl3-synth
can be built-in while CONFIG_SND_SEQUENCER_OSS=m.

This patch fixes these places to build properly for the new kconfig
dependency.  In the end, we had to use ifneq() to satisfy the
requirement.  It's a bit ugly, but lesser evil.

a8f20fd25b ALSA: hda - set input_path bitmap to zero after moving it to new place
Recently we met a problem, the codec has valid adcs and input pins,
and they can form valid input paths, but the driver does not build
valid controls for them like "Mic boost", "Capture Volume" and
"Capture Switch".

Through debugging, I found the driver needs to shrink the invalid
adcs and input paths for this machine, so it will move the whole
column bitmap value to the previous column, after moving it, the
driver forgets to set the original column bitmap value to zero, as a
result, the driver will invalidate the path whose index value is the
original colume bitmap value. After executing this function, all
valid input paths are invalidated by a mistake, there are no any
valid input paths, so the driver won't build controls for them.
