make C=2 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- xxx.o
When I use the command above to do a 'make C=2' check on any object file,
the following warnings are always output:
CHECK arch/arm64/kernel/vdso/vgettimeofday.c
arch/arm64/kernel/vdso/vgettimeofday.c:9:5: warning:

Therefore, the declaration of the three functions is added to eliminate

In the restore path, swsusp_arch_suspend_exit uses copy_page() to
over-write memory. However, with features like KFENCE enabled, there could
be situations where it may have marked some pages as not valid, due to
which it could be reported as invalid accesses.
Consider a situation where page 'P' was part of the hibernation image.
Now, when the resume kernel tries to restore the pages, the same page 'P'
is already in use in the resume kernel and is kfence protected, due to
which its mapping is removed from linear map. Since restoring pages happens
with the resume kernel page tables, we would end up accessing 'P' during
copy and results in kernel pagefault.
The proposed fix tries to solve this issue by marking PTE as valid for such
kfence protected pages.

end key should be equal to start unless NFT_SET_EXT_KEY_END is present.
Its possible to add elements that only have a start key
("{ 1.0.0.0 . 2.0.0.0 }") without an internval end.
Insertion treats this via:
if (nft_set_ext_exists(ext, NFT_SET_EXT_KEY_END))
end = (const u8 *)nft_set_ext_key_end(ext)->data;
else
end = start;
but removal side always uses nft_set_ext_key_end().
This is wrong and leads to garbage remaining in the set after removal
next lookup/insert attempt will give:

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
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_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().

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.

just hlt"
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.

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).
