On some platforms there is a padding hole in the nft_verdict
structure, between the verdict code and the chain pointer.
On element insertion, if the new element clashes with an existing one and
NLM_F_EXCL flag isn't set, we want to ignore the -EEXIST error as long as
the data associated with duplicated element is the same as the existing
one. The data equality check uses memcmp.
For normal data (NFT_DATA_VALUE) this works fine, but for NFT_DATA_VERDICT
padding area leads to spurious failure even if the verdict data is the
same.
This then makes the insertion fail with 'already exists' error, even
though the new "key : data" matches an existing entry and userspace
told the kernel that it doesn't want to receive an error indication.

====================
net: Support STP on bridge in non-root netns.
Currently, STP does not work in non-root netns as llc_rcv() drops
packets from non-root netns.
This series fixes it by making some protocol handlers netns-aware,
which are called from llc_rcv() as follows:
llc_rcv()
|
|- sap->rcv_func : registered by llc_sap_open()
|
| * functions : regsitered by register_8022_client()
| -> No in-kernel user call register_8022_client()
|
| * snap_rcv()
| |
| `- proto->rcvfunc() : registered by register_snap_client()
|
| * aarp_rcv() : drop packets from non-root netns
| * atalk_rcv() : drop packets from non-root netns
|
| * stp_pdu_rcv()
| |
| `- garp_protos[]->rcv() : registered by stp_proto_register()
|
| * garp_pdu_rcv() : netns-aware
| * br_stp_rcv() : netns-aware
|
|- llc_type_handlers[llc_pdu_type(skb) - 1]
|
| * llc_sap_handler() : NOT netns-aware (Patch 1)
| * llc_conn_handler() : NOT netns-aware (Patch 2)
|
`- llc_station_handler
* llc_station_rcv() : netns-aware
Patch 1 & 2 convert not-netns-aware functions and Patch 3 remove the
netns restriction in llc_rcv().
Note this series does not namespacify AF_LLC so that these patches
can be backported to stable without conflicts (at least to 4.14.y).
Another series that adds netns support for AF_LLC will be targeted
to net-next later.

Now these upper layer protocol handlers can be called from llc_rcv()
as sap->rcv_func(), which is registered by llc_sap_open().
* function which is passed to register_8022_client()
-> no in-kernel user calls register_8022_client().
* snap_rcv()
`- proto->rcvfunc() : registered by register_snap_client()
-> aarp_rcv() and atalk_rcv() drop packets from non-root netns
* stp_pdu_rcv()
`- garp_protos[]->rcv() : registered by stp_proto_register()
-> garp_pdu_rcv() and br_stp_rcv() are netns-aware
So, we can safely remove the netns restriction in llc_rcv().

We will remove this restriction in llc_rcv() in the following patch,
which means that the protocol handler must be aware of netns.
if (!net_eq(dev_net(dev), &init_net))
goto drop;
llc_rcv() fetches llc_type_handlers[llc_pdu_type(skb) - 1] and calls it
if not NULL.
If the PDU type is LLC_DEST_CONN, llc_conn_handler() is called to pass
skb to corresponding sockets. Then, we must look up a proper socket in
the same netns with skb->dev.
llc_conn_handler() calls __llc_lookup() to look up a established or
litening socket by __llc_lookup_established() and llc_lookup_listener().
Both functions iterate on a list and call llc_estab_match() or
llc_listener_match() to check if the socket is the correct destination.
However, these functions do not check netns.
Also, bind() and connect() call llc_establish_connection(), which
finally calls __llc_lookup_established(), to check if there is a
conflicting socket.
Let's test netns in llc_estab_match() and llc_listener_match().

We will remove this restriction in llc_rcv() soon, which means that the

if (!net_eq(dev_net(dev), &init_net))

llc_rcv() fetches llc_type_handlers[llc_pdu_type(skb) - 1] and calls it

If the PDU type is LLC_DEST_SAP, llc_sap_handler() is called to pass skb
to corresponding sockets. Then, we must look up a proper socket in the
same netns with skb->dev.
If the destination is a multicast address, llc_sap_handler() calls
llc_sap_mcast(). It calculates a hash based on DSAP and skb->dev->ifindex,
iterates on a socket list, and calls llc_mcast_match() to check if the
socket is the correct destination. Then, llc_mcast_match() checks if
skb->dev matches with llc_sk(sk)->dev. So, we need not check netns here.
OTOH, if the destination is a unicast address, llc_sap_handler() calls
llc_lookup_dgram() to look up a socket, but it does not check the netns.
Therefore, we need to add netns check in llc_lookup_dgram().

ALSA: Make control API taking controls_rwsem consistently
A few ALSA control API helpers like snd_ctl_rename(), snd_ctl_remove()
and snd_ctl_find_*() suppose the callers taking card->controls_rwsem.
But it's error-prone and fragile. This patch set tries to change
those API functions to take the card->controls>rwsem internally by
themselves, so that the drivers don't need to take care of lockings.
After applying this patch set, only a couple of places still touch
card->controls_rwsem (which are OK-ish as they need for traversing the
control linked list).

For reducing the unnecessary use of controls_rwsem in the drivers,
this patch adds a new variant for snd_ctl_find_*() helpers:
snd_ctl_find_id_locked() and snd_ctl_find_numid_locked() look for a
kctl element inside the card->controls_rwsem -- that is, doing the
very same as what snd_ctl_find_id() and snd_ctl_find_numid() did until
now. snd_ctl_find_id() and snd_ctl_find_numid() remain same,
i.e. still unlocked version, but they will be switched to locked
version once after all callers are replaced.
The patch also replaces the calls of snd_ctl_find_id() and
snd_ctl_find_numid() in a few places; all of those are places where we
know that the functions are called properly with controls_rwsem held.
All others are without rwsem (although they should have been).
After this patch, we'll turn on the locking in snd_ctl_find_id() and
snd_ctl_find_numid() to be more race-free.

The controls_rwsem of snd_card object is rather an internal lock, and
not really meant to be used by others for its data protection.
This patch addresses it by replacing the controls_rwsem usages with
the own (new) mutex.
Note that the up_write() and down_write() calls around
gbaudio_remove_component_controls() are simply dropped without
replacement. These temporary up/down were a workaround since
gbaudio_remove_component_controls() itself took the rwsem. Now it was
also gone, we can clean up the workaround, too.

So far, snd_ctl_remove() requires its caller to take
card->controls_rwsem manually before the call for avoiding possible
races. However, many callers don't care and miss the locking.
Basically it's cumbersome and error-prone to enforce it to each
caller. Moreover, card->controls_rwsem is a field that should be used
only by internal or proper helpers, and it's not to be touched at
random external places.
This patch is an attempt to make those calls more consistent: now
snd_ctl_remove() takes the card->controls_rwsem internally, just like
other API functions for kctls. Since a few callers already take the
controls_rwsem locks, the patch removes those locks at the same time,
too.

snd_ctl_rename() expects that card->controls_rwsem is held in the
caller side for avoiding possible races, but actually no one really
did that. It's likely because this operation is done usually only at
the device initialization where no race can happen. But, it's still
safer to take a lock, so we just take the lock inside snd_ctl_rename()
like most of other API functions do.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

This reverts commit 3f4ca5fafc08881d7a57daa20449d171f2887043.
Commit 3f4ca5fafc08 ("tcp: avoid the lookup process failing to get sk in
ehash table") reversed the order in how a socket is inserted into ehash
to fix an issue that ehash-lookup could fail when reqsk/full sk/twsk are
swapped. However, it introduced another lookup failure.
The full socket in ehash is allocated from a slab with SLAB_TYPESAFE_BY_RCU
and does not have SOCK_RCU_FREE, so the socket could be reused even while
it is being referenced on another CPU doing RCU lookup.
Let's say a socket is reused and inserted into the same hash bucket during
lookup. After the blamed commit, a new socket is inserted at the end of
the list. If that happens, we will skip sockets placed after the previous
position of the reused socket, resulting in ehash lookup failure.
As described in Documentation/RCU/rculist_nulls.rst, we should insert a
new socket at the head of the list to avoid such an issue.
This issue, the swap-lookup-failure, and another variant reported in [0]
can all be handled properly by adding a locked ehash lookup suggested by
Eric Dumazet [1].
However, this issue could occur for every packet, thus more likely than
the other two races, so let's revert the change for now.

This reverts commit 2f3d08f074b0 ("intel_idle: Add support for using
intel_idle in a VM guest using just hlt"), because it causes functional
issues to appear and it is not really useful without a related commit
that got reverted previously.

Commit 349355ce3a05 ("ARM: OMAP2+: Drop legacy platform data for omap4 mcbsp")
dropped prcm_fck for omap4, so the clk_src might not be available making the
clk_get(src) fail. In such cases, rely on the devicetree to assign
the correct parent.

To ensure that DPCM takes into account the backend hardware limitations
when user space queries the hw_params of a device, we need to add
dpcm_merged_format, dpcm_merged_chan, and dpcm_merged_rate to the FE
dai_links.
This patch includes only stereo FE dai_links, since multi-channel FEs
may be reserved for specific purposes. Therefore, it may not be
appropriate to consider BE conditions.

The HP Laptop 15s-eq2xxx uses ALC236 codec and controls the mute LED using
COEF 0x07 index 1. No existing quirk covers this configuration.
Adds a new quirk and enables it for the device.

Currently the regcache core unconditionally enables async I/O for all cache
types, causing problems for the maple tree cache which dynamically allocates
the buffers used to write registers to the device since async requires the
buffers to be kept around until the I/O has been completed.
This use of async I/O is mainly for the rbtree cache which stores data in
a format directly usable for regmap_raw_write(), though there is a special
case for single register writes which would also have allowed it to be used
with the flat cache. It is a bit of a landmine for other caches since it
implicitly converts sync operations to async, and with modern hardware it
is not clear that async I/O is actually a performance win as shown by the
performance work David Jander did with SPI. In multi core systems the cost
of managing concurrency ends up swamping the performance benefit and almost
all modern systems are multi core.
Address this by pushing the enablement of async I/O down into the rbtree
cache where it is actively used, avoiding surprises for other cache
implementations.

This allows to get rid of a call to pwmchip_remove() in the error path. There
is no .remove function for this driver, so this change fixes a resource leak
when a gpio-mvebu device is unbound.

This reverts commit 606787fed7268feb256957872586370b56af697a.
ELFv1 with LE has never been a thing, and people who try to make ELFv1 LE
binaries are maniacs who need to be stopped, but unfortunately there are
ELFv1 LE binaries out there in the wild.
One such binary is the ppc64el (as Debian calls it) helper for
arch-test[0], a tool for detecting architectures that can be executed on a
given machine by means of attempting to execute helper binaries compiled
for each architecture and seeing which binaries succeed and fail. The
helpers are small snippets of assembly, and the ppc64el assembly doesn't
include the right directives to generate an ELFv2 binary.
This results in arch-test incorrectly determining that a ppc64el kernel
can't execute a ppc64el userspace, which in turn means that a number of
developer tools such as debootstrap will break (assuming arch-test is
installed).
