Check for nat chain dependency only, which is the one that can
actually crash the kernel. Don't care if mangle, filter and security
specific match and targets are used out of their scope, they are
harmless.
This restores iptables-compat with mangle specific match/target when
used out of the OUTPUT chain, that are actually emulated through filter
chains, which broke when performing strict validation.

This will fix no sound in Linux system after reboot from windows.
Change log:
- alc662_fill_coef() is replaced with alc_fill_eapd_coef_idx()
and move into alc_auto_init_amp().
- For ALC262, ALC267, ALC268, ALC269, ALC233, ALC255, ALC280, ALC282,
ALC283, ALC284, ALC285, ALC286, ALC288, ALC290, ALC292, ALC293, ALC294,
ALC668, ALC888VC, ALC888VD, ALC891, ALC892, ALC898 and ALC1150, add update
COEF control for EAPD setting.
- Remove alc269_fill_coef() for update EAPD control line.
ADDITIONAL NOTE:
Many Realtek cdoecs have a COEF bit to switch the master amp control
between COEF and EAPD. Windows drivers seem using COEF while we use
EAPD, which is more standard. As a result, some system suffer from
the silent output when booting after Windows. This patch sets the
COEF bits on the relevant codecs properly to switch to EAPD control.

The while loop in sock_fanout_read_ring() checks mmap region
bounds after access, causing it to segfault. Fix it to check
count before accessing header->tp_status. This problem can be
reproduced consistently when the test in run as follows:

ip_vs_prepare_tunneled_skb() ignores ->sk when allocating a new

the uninitialized ->sk from a newly allocated skb to leak through

On sh73a0/kzm9g-legacy, probing of the i2c masters fails with:
i2c-sh_mobile i2c-sh_mobile.0: timing values out of range: L/H=0x208/0x1bf
sh_mobile: probe of i2c-sh_mobile.0 failed with error -22
According to the datasheet, the transfer rate is derived from the HP
clock (which runs at 104 MHz) divided by two. Hence
i2c_sh_mobile_platform_data.clks_per_count should be set to two.
Now probing succeeds, and i2c works:

====================
net: bcmgenet: power management related fixes
These two patches fixes issues seen while testing power management on
platforms using the GENET driver.
First patch fixes an issue with the PHY state machine queuing work after
resume since we are not properly detached from it.
Second patch fixes an issue with GENET interfaces that were not properly
restored to a working state after a S3 suspend/resume cycle.
====================

In case an interface has been brought down before entering S3, and then
brought up out of S3, all the initialization done during
bcmgenet_probe() by bcmgenet_mii_init() calling bcmgenet_mii_config() is
just lost since register contents are restored to their reset values.
Re-apply this configuration anytime we call bcmgenet_open() to make sure
our port multiplexer is properly configured to match the PHY interface.
Since we are now calling bcmgenet_mii_config() everytime bcmgenet_open()
is called, make sure we only print the message during initialization
time not to pollute the console.

phy_disconnect() is the only way to guarantee that we are not going to
schedule more work on the PHY state machine workqueue for that
particular PHY device.
This fixes an issue where a network interface was suspended prior to a
system suspend/resume cycle and would then be resumed as part of
mdio_bus_resume(), since the GENET interface clocks would have been
disabled, this basically resulted in bus errors to appear since we are
invoking the GENET driver adjust_link() callback.

The initial state of the device's need_restore flag should'nt depend on
the current state of the PM domain. For example it should be perfectly
valid to attach an inactive device to a powered PM domain.
The pm_genpd_dev_need_restore() API allow us to update the need_restore
flag to somewhat cope with such scenarios. Typically that should have
been done from drivers/buses ->probe() since it's those that put the
requirements on the value of the need_restore flag.
Until recently, the Exynos SOCs were the only user of the
pm_genpd_dev_need_restore() API, though invoking it from a centralized
location while adding devices to their PM domains.
Due to that Exynos now have swithed to the generic OF-based PM domain
look-up, it's no longer possible to invoke the API from a centralized
location. The reason is because devices are now added to their PM
domains during the probe sequence.
Commit "ARM: exynos: Move to generic PM domain DT bindings"
did the switch for Exynos to the generic OF-based PM domain look-up,
but it also removed the call to pm_genpd_dev_need_restore(). This
caused a regression for some of the Exynos drivers.
To handle things more properly in the generic PM domain, let's change
the default initial value of the need_restore flag to reflect that the
state is unknown. As soon as some of the runtime PM callbacks gets
invoked, update the initial value accordingly.
Moreover, since the generic PM domain is verifying that all devices
are both runtime PM enabled and suspended, using pm_runtime_suspended()
while pm_genpd_poweroff() is invoked from the scheduled work, we can be
sure of that the PM domain won't be powering off while having active
devices.
Do note that, the generic PM domain can still only know about active
devices which has been activated through invoking its runtime PM resume
callback. In other words, buses/drivers using pm_runtime_set_active()
during ->probe() will still suffer from a race condition, potentially
probing a device without having its PM domain being powered. That issue
will have to be solved using a different approach.
This a log from the boot regression for Exynos5, which is being fixed in
this patch.

Based on the reference clock, which could be 25MHz or 40MHz,
AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550.
But, when a chip reset is done, processing the initvals
sets the register back to the default value.
Fix this by moving the code in ath9k_hw_init_pll() to
ar9003_hw_override_ini(). Also, do this override for AR9531.

When advertised capabilities are changed with mii-tool, such as:
mii-tool -A 10baseT
the existing handler has two errors.
- An actual PHY register value is provided by mii-tool, and this
must be mapped to internal state with mii_adv_to_ethtool_adv_t().
- The PHY state machine needs to be told that autonegotiation has
again been performed. If not, the MAC will not be notified of
the new link speed and duplex, resulting in a possible config
mismatch.

RT2800 and newer hardware require padding between header and payload if
header length is not multiple of 4.
For historical reasons we also align payload to to 4 bytes boundary, but
such alignment is not needed on modern H/W.
Patch fixes skb_under_panic problems reported from time to time:
https://bugzilla.kernel.org/show_bug.cgi?id=84911
https://bugzilla.kernel.org/show_bug.cgi?id=72471
http://marc.info/?l=linux-wireless&m=139108549530402&w=2
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591
Panic happened because we eat 4 bytes of skb headroom on each
(re)transmission when sending frame without the payload and the header
length not being multiple of 4 (i.e. QoS header has 26 bytes). On such
case because paylad_aling=2 is bigger than header_align=0 we increase
header_align by 4 bytes. To prevent that we could change the check to:
if (payload_length && payload_align > header_align)
header_align += 4;
but not aligning payload at all is more effective and alignment is not
really needed by H/W (that has been tested on OpenWrt project for few
years now).

This is bad because of two things, we can bring down a machine from
user space when auth_enable=1, but also we would leave security sensitive
keying material in memory without clearing it after use. The issue is
that sctp_auth_create_key() already sets the refcount to 1, but after
allocation sctp_auth_set_key() does an additional refcount on it, and
thus leaving it around when we free the socket.

packet
An SCTP server doing ASCONF will panic on malformed INIT ping-of-death
in the form of:
------------ INIT[PARAM: SET_PRIMARY_IP] ------------>
While the INIT chunk parameter verification dissects through many things
in order to detect malformed input, it misses to actually check parameters
inside of parameters. E.g. RFC5061, section 4.2.4 proposes a 'set primary
IP address' parameter in ASCONF, which has as a subparameter an address
parameter.
So an attacker may send a parameter type other than SCTP_PARAM_IPV4_ADDRESS
or SCTP_PARAM_IPV6_ADDRESS, param_type2af() will subsequently return 0
and thus sctp_get_af_specific() returns NULL, too, which we then happily
dereference unconditionally through af->from_addr_param().

In ppp_ioctl(), bpf_prog_create() is called inside ppp_lock, which
eventually calls vmalloc() and hits BUG_ON() in vmalloc.c. This patch
works around the problem by moving the allocation outside the lock.
The bug was revealed by the recent change in net/core/filter.c, as it
allocates via vmalloc() instead of kmalloc() now.

Audit rules disappear when an inode they watch is evicted from the cache.
This is likely not what we want.
The guilty commit is "fsnotify: allow marks to not pin inodes in core",
which didn't take into account that audit_tree adds watches with a zero
mask.
Adding any mask should fix this.

Because we build kernels with drivers built in for many platforms, it's
normal for the ibmpowernv driver to be loaded on systems that don't have
the appropriate hardware.
Currently the driver spams the log with:
ibmpowernv ibmpowernv.0: Opal node 'sensors' not found
ibmpowernv: Platfrom driver probe failed
But there is no error, this machine is not a powernv and doesn't have
the hardware. So change the sensors message to dev_dbg(), and only print
an error about the probe failing if it's not ENODEV.
Also fix the spelling of "Platfrom" and print the actual error value.

tunnel is set
Currenly we only support Large-Send and TX checksum offloads for
encapsulated traffic of type VXLAN. We must make sure to advertize
these offloads up to the stack only when VXLAN tunnel is set.
Failing to do so, would mislead the the networking stack to assume
that the driver can offload the internal TX checksum for GRE packets
and other buggy schemes.

As obj->map_and_fenceable computation has changed to only be set when
the object is bound inside the global GTT (and is suitable aligned to a
fence region) we need to accommodate those changes when the tiling is
adjusted. The easiest solution is to unbind from the global GTT if we
are currently fenceable, but will not be after the tiling change.
The bug has been exposed by
commit f8fcadba218fe6d23b2e353fea1cf0a4be4c9454
Author: Chris Wilson <chris@chris-wilson.co.uk>

drm/i915: Only mark as map-and-fenceable when bound into the GGTT
which tried to fix an oversight from
commit e6a844687cf929ec053c7578d5ecc794a8a6c5cf
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Mon Aug 11 12:00:12 2014 +0200
drm/i915: Force CPU relocations if not GTT mapped
which changed the handling of obj->map_and_fenceable.
Note that the alignment check is a vestige from our attempts to reduce
the alignment requirements of tiled but unfenced buffers on
gen2/3. Also, that was when unbinding from the GTT meant UC writes and
clflushing, so we went to great pains to avoid such.
That leaves the actual bug of setting map_and_fenceable to true if we're
not bound to ggtt, which violates the change introduced in the above
patch. Unbinding in that case really looks like the simplest and safest
option, we have to do it anyway.

Currently if the user passes an invalid value on the kernel command line
then the kernel will crash during argument parsing. On most systems this
is very hard to debug because the console hasn't been initialized yet.
This is a regression due to commit 51e158c12aca ("param: hand arguments
after -- straight to init") which, in response to the systemd debug
controversy, made it possible to explicitly pass arguments to init. To
achieve this parse_args() was extended from simply returning an error
code to returning a pointer. Regretably the new init args logic does not
perform a proper validity check on the pointer resulting in a crash.
This patch fixes the validity check. Should the check fail then no arguments
will be passed to init. This is reasonable and matches how the kernel treats
its own arguments (i.e. no error recovery).

If the read loop in trace_buffers_splice_read() keeps failing due to
memory allocation failures without reading even a single page then this
function will keep busy looping.
Remove the risk for that by exiting the function if memory allocation

On a !PREEMPT kernel, attempting to use trace-cmd results in a soft

The problem is this: tracing_buffers_splice_read() calls
ring_buffer_wait() to wait for data in the ring buffers. The buffers
are not empty so ring_buffer_wait() returns immediately. But
tracing_buffers_splice_read() calls ring_buffer_read_page() with full=1,
meaning it only wants to read a full page. When the full page is not
available, tracing_buffers_splice_read() tries to wait again with
ring_buffer_wait(), which again returns immediately, and so on.
Fix this by adding a "full" argument to ring_buffer_wait() which will
make ring_buffer_wait() wait until the writer has left the reader's
page, i.e. until full-page reads will succeed.

Switch over the msgctl, shmat, shmctl and semtimedop syscalls to use the compat
layer. The problem was found with the debian procenv package, which called
shmctl(0, SHM_INFO, &info);
in which the shmctl syscall then overwrote parts of the surrounding areas on
the stack on which the info variable was stored and thus lead to a segfault
later on.
Additionally fix the definition of struct shminfo64 to use unsigned longs like
the other architectures. This has no impact on userspace since we only have a
32bit userspace up to now.
