[ Upstream commit 9b368814b336b0a1a479135eb2815edbc00efd3c ]
We need to update the skb->csum after pulling the skb, otherwise
an unnecessary checksum (re)computation can ocure for IGMP/MLD packets
in the bridge code. Additionally this fixes the following splats for
network devices / bridge ports with support for and enabled RX checksum

commit 95272c29378ee7dc15f43fa2758cb28a5913a06d upstream.
-ftracer can duplicate asm blocks causing compilation to fail in
noclone functions. For example, KVM declares a global variable
in an asm like
asm("2: ... \n
.pushsection data \n
.global vmx_return \n
vmx_return: .long 2b");
and -ftracer causes a double declaration.

commit 3debb0a9ddb16526de8b456491b7db60114f7b5e upstream.
The trace_printk() code will allocate extra buffers if the compile detects
that a trace_printk() is used. To do this, the format of the trace_printk()
is saved to the __trace_printk_fmt section, and if that section is bigger
than zero, the buffers are allocated (along with a message that this has
happened).
If trace_printk() uses a format that is not a constant, and thus something
not guaranteed to be around when the print happens, the compiler optimizes
the fmt out, as it is not used, and the __trace_printk_fmt section is not
filled. This means the kernel will not allocate the special buffers needed
for the trace_printk() and the trace_printk() will not write anything to the
tracing buffer.
Adding a "__used" to the variable in the __trace_printk_fmt section will
keep it around, even though it is set to NULL. This will keep the string
from being printed in the debugfs/tracing/printk_formats section as it is
not needed.

commit 378c6520e7d29280f400ef2ceaf155c86f05a71a upstream.
This commit fixes the following security hole affecting systems where
all of the following conditions are fulfilled:
- The fs.suid_dumpable sysctl is set to 2.
- The kernel.core_pattern sysctl's value starts with "/". (Systems
where kernel.core_pattern starts with "|/" are not affected.)
- Unprivileged user namespace creation is permitted. (This is
true on Linux >=3.8, but some distributions disallow it by
default using a distro patch.)
Under these conditions, if a program executes under secure exec rules,
causing it to run with the SUID_DUMP_ROOT flag, then unshares its user
namespace, changes its root directory and crashes, the coredump will be
written using fsuid=0 and a path derived from kernel.core_pattern - but
this path is interpreted relative to the root directory of the process,
allowing the attacker to control where a coredump will be written with
root privileges.
To fix the security issue, always interpret core_pattern for dumps that
are written under SUID_DUMP_ROOT relative to the root directory of init.

commit 2b021cbf3cb6208f0d40fd2f1869f237934340ed upstream.
Before 2e91fa7f6d45 ("cgroup: keep zombies associated with their
original cgroups"), all dead tasks were associated with init_css_set.
If a zombie task is requested for migration, while migration prep
operations would still be performed on init_css_set, the actual
migration would ignore zombie tasks. As init_css_set is always valid,
this worked fine.
However, after 2e91fa7f6d45, zombie tasks stay with the css_set it was
associated with at the time of death. Let's say a task T associated
with cgroup A on hierarchy H-1 and cgroup B on hiearchy H-2. After T
becomes a zombie, it would still remain associated with A and B. If A
only contains zombie tasks, it can be removed. On removal, A gets
marked offline but stays pinned until all zombies are drained. At
this point, if migration is initiated on T to a cgroup C on hierarchy
H-2, migration path would try to prepare T's css_set for migration and
trigger the following.

It doesn't make sense to prepare migration for css_sets pointing to
dead cgroups as they are guaranteed to contain only zombies which are
ignored later during migration. This patch makes cgroup destruction
path mark all affected css_sets as dead and updates the migration path
to ignore them during preparation.

GPF caused by a line discipline which does not define a receive_buf()
method.
However, the vt driver (and speakup driver also) pushes selection
data directly to the line discipline receive_buf() method via
tty_ldisc_receive_buf(). Fix the same problem in tty_ldisc_receive_buf().

commit b84106b4e2290c081cdab521fa832596cdfea246 upstream.
The PCI config header (first 64 bytes of each device's config space) is
defined by the PCI spec so generic software can identify the device and
manage its usage of I/O, memory, and IRQ resources.
Some non-spec-compliant devices put registers other than BARs where the
BARs should be. When the PCI core sizes these "BARs", the reads and writes
it does may have unwanted side effects, and the "BAR" may appear to
describe non-sensical address space.
Add a flag bit to mark non-compliant devices so we don't touch their BARs.
Turn off IO/MEM decoding to prevent the devices from consuming address
space, since we can't read the BARs to find out what that address space
would be.

commit 81ad4276b505e987dd8ebbdf63605f92cd172b52 upstream.
In some cases, platform thermal driver may report invalid trip points,
thermal core should not take any action for these trip points.
This fixed a regression that bogus trip point starts to screw up thermal
control on some Lenovo laptops, after
commit bb431ba26c5cd0a17c941ca6c3a195a3a6d5d461

Thermal: initialize thermal zone device correctly
After thermal zone device registered, as we have not read any
temperature before, thus tz->temperature should not be 0,
which actually means 0C, and thermal trend is not available.
In this case, we need specially handling for the first
thermal_zone_device_update().
Both thermal core framework and step_wise governor is
enhanced to handle this. And since the step_wise governor
is the only one that uses trends, so it's the only thermal
governor that needs to be updated.

commit b9a1a743818ea3265abf98f9431623afa8c50c86 upstream.
ARM64 allmodconfig produces a bunch of warnings when building the
samsung ASoC code:
sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data':
sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
playback_data->filter_data = (void *)playback->channel;
sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
capture_data->filter_data = (void *)capture->channel;
We could easily shut up the warning by adding an intermediate cast,
but there is a bigger underlying problem: The use of IORESOURCE_DMA
to pass data from platform code to device drivers is dubious to start
with, as what we really want is a pointer that can be passed into
a filter function.
Note that on s3c64xx, the pl08x DMA data is already a pointer, but
gets cast to resource_size_t so we can pass it as a resource, and it
then gets converted back to a pointer. In contrast, the data we pass
for s3c24xx is an index into a device specific table, and we artificially
convert that into a pointer for the filter function.

This adds a routine, dev_pm_opp_set_rate(), responsible for configuring
power-supply and clock source for an OPP.
The OPP is found by matching against the target_freq passed to the
routine. This shall replace similar code present in most of the OPP
users and help simplify them a lot.

This allows the OPP core to request/free the regulator resource,
attached to a device OPP. The regulator device is fetched using the name
provided by the driver, while calling: dev_pm_opp_set_regulator().
This will work for both OPP-v1 and v2 bindings.
This is a preliminary step for moving the OPP switching logic into the
OPP core.

OPP bindings (for few properties) allow a platform to choose a
value/range among a set of available options. The options are present as
opp-<prop>-<name>, where the platform needs to supply the <name> string.
The OPP properties which allow such an option are: opp-microvolt and
opp-microamp.
Add support to the OPP-core to parse these bindings, by introducing
dev_pm_opp_{set|put}_prop_name() APIs.

Add support to scale reverse thresholds on VADC_TM refresh
peripheral for voltage measurements such as vbatt, vph_pwr,
thermistor channels, PMIC die temperature.
VADC_TM refresh uses one interrupt for high and low threshold
notification. Update the sequence to check the respective
sensors status for high/low threshold crossing for the VADC_TM
refresh and notify the clients on a threshold crossing.

DP/DM linestate is needed by the QUSB2 PHY driver to configure the
polarity of DP/DM transition triggers for exiting low power mode.
This was previously available via the QUSB2PHY_PORT_UTMI_STATUS
PHY register which is now deprecated. In order to correctly determine
the interrupt polarity we need to pass the current operating speed
to the QUSB2 PHY driver. The PHY driver uses mode, speed and
cable connection status to determine the linestate and configure
interrupt polarities for wake up. Add logic to determine operating
speed for host and device mode cases.

Add APIs to send and receive vendor defined messages (VDM) over
USB PD. A handler for a standard or vendor ID (SVID) can register
callbacks to be notified of reception of VDM messages. One
use case is for another kernel driver, such as DisplayPort, to be
able to be notified when an Alternate Mode adapter is connected
to the Type-C port in order to enter modal operation. SVID
handlers should maintain their own state and timer resources
in order to comply with the Power Delivery Specification.

Currently power supply name is passed to get the battery profile
in of_batterydata_get_best_profile(). This creates a dependency
of waiting for the driver that has the power supply class device.
Improve this by passing the battery id directly to the API. This
way, getting battery id will be the responsibility of caller.

commit 90d0f0f11588ec692c12f9009089b398be395184 upstream.
For !BIO_CLONED bio, we can use .bi_vcnt safely, but it
doesn't mean we can just simply return .bi_io_vec[.bi_vcnt - 1]
because the start postion may have been moved in the middle of
the bvec, such as splitting in the middle of bvec.
Fixes: 7bcd79ac50d9(block: bio: introduce helpers to get the 1st and last bvec)

commit dc17147de328a74bbdee67c1bf37d2f1992de756 upstream.
Commit f37755490fe9b ("tracepoints: Do not trace when cpu is offline") added
a check to make sure that tracepoints only get called when the cpu is
online, as it uses rcu_read_lock_sched() for protection.
Commit 3a630178fd5f3 ("tracing: generate RCU warnings even when tracepoints
are disabled") added lockdep checks (including rcu checks) for events that
are not enabled to catch possible RCU issues that would only be triggered if
a trace event was enabled. Commit f37755490fe9b only stopped the warnings
when the trace event was enabled but did not prevent warnings if the trace
event was called when disabled.
To fix this, the cpu online check is moved to where the condition is added
to the trace event. This will place the cpu online check in all places that
it may be used now and in the future.
Fixes: f37755490fe9b ("tracepoints: Do not trace when cpu is offline")
