3ec44268e2 ASoC: cs42l56: fix DT probe
[ Upstream commit e18c6da62edc780e4f4f3c9ce07bdacd69505182 ]

While looking through legacy platform data users, I noticed that
the DT probing never uses data from the DT properties, as the
platform_data structure gets overwritten directly after it
is initialized.

There have never been any boards defining the platform_data in
the mainline kernel either, so this driver so far only worked
with patched kernels or with the default values.

For the benefit of possible downstream users, fix the DT probe
by no longer overwriting the data.

7fc4e7191e ALSA: hda: Do not unset preset when cleaning up codec
[ Upstream commit 87978e6ad45a16835cc58234451111091be3c59a ]

Several functions that take part in codec's initialization and removal
are re-used by ASoC codec drivers implementations. Drivers mimic the
behavior of hda_codec_driver_probe/remove() found in
sound/pci/hda/hda_bind.c with their component->probe/remove() instead.

One of the reasons for that is the expectation of
snd_hda_codec_device_new() to receive a valid pointer to an instance of
struct snd_card. This expectation can be met only once sound card
components probing commences.

As ASoC sound card may be unbound without codec device being actually
removed from the system, unsetting ->preset in
snd_hda_codec_cleanup_for_unbind() interferes with module unload -> load
scenario causing null-ptr-deref. Preset is assigned only once, during
device/driver matching whereas ASoC codec driver's module reloading may
occur several times throughout the lifetime of an audio stack.

7d3a5ec579 ASoC: Intel: sof_rt5682: always set dpcm_capture for amplifiers
[ Upstream commit 324f065cdbaba1b879a63bf07e61ca156b789537 ]

The amplifier may provide hardware support for I/V feedback, or
alternatively the firmware may generate an echo reference attached to
the SSP and dailink used for the amplifier.

To avoid any issues with invalid/NULL substreams in the latter case,
always unconditionally set dpcm_capture.

0a626e27f9 Fix page corruption caused by racy check in __free_pages
commit 462a8e08e0e6287e5ce13187257edbf24213ed03 upstream.

When we upgraded our kernel, we started seeing some page corruption like
the following consistently:

  BUG: Bad page state in process ganesha.nfsd  pfn:1304ca
  page:0000000022261c55 refcount:0 mapcount:-128 mapping:0000000000000000 index:0x0 pfn:0x1304ca

   alloc_pages_current+0x87/0xf0
   skb_page_frag_refill+0x84/0x110
   ...

Sometimes, it would also show up as corruption in the free list pointer
and cause crashes.

After bisecting the issue, we found the issue started from commit
e320d3012d25 ("mm/page_alloc.c: fix freeing non-compound pages"):

	if (put_page_testzero(page))
		free_the_page(page, order);
	else if (!PageHead(page))
		while (order-- > 0)
			free_the_page(page + (1 << order), order);

So the problem is the check PageHead is racy because at this point we
already dropped our reference to the page.  So even if we came in with
compound page, the page can already be freed and PageHead can return
false and we will end up freeing all the tail pages causing double free.

8eee3521bc riscv: Fixup race condition on PG_dcache_clean in flush_icache_pte
commit 950b879b7f0251317d26bae0687e72592d607532 upstream.

In commit 588a513d3425 ("arm64: Fix race condition on PG_dcache_clean
in __sync_icache_dcache()"), we found RISC-V has the same issue as the
previous arm64. The previous implementation didn't guarantee the correct
sequence of operations, which means flush_icache_all() hasn't been
called when the PG_dcache_clean was set. That would cause a risk of page
synchronization.

4f518a4a79 usb: typec: altmodes/displayport: Fix probe pin assign check
commit 54e5c00a4eb0a4c663445b245f641bbfab142430 upstream.

While checking Pin Assignments of the port and partner during probe, we
don't take into account whether the peripheral is a plug or receptacle.

This manifests itself in a mode entry failure on certain docks and
dongles with captive cables. For instance, the Startech.com Type-C to DP
dongle (Model #CDP2DP) advertises its DP VDO as 0x405. This would fail
the Pin Assignment compatibility check, despite it supporting
Pin Assignment C as a UFP.

Update the check to use the correct DP Pin Assign macros that
take the peripheral's receptacle bit into account.

dd965ad39d btrfs: free device in btrfs_close_devices for a single device filesystem
commit 5f58d783fd7823b2c2d5954d1126e702f94bfc4c upstream.

We have this check to make sure we don't accidentally add older devices
that may have disappeared and re-appeared with an older generation from
being added to an fs_devices (such as a replace source device). This
makes sense, we don't want stale disks in our file system. However for
single disks this doesn't really make sense.

I've seen this in testing, but I was provided a reproducer from a
project that builds btrfs images on loopback devices. The loopback
device gets cached with the new generation, and then if it is re-used to
generate a new file system we'll fail to mount it because the new fs is
"older" than what we have in cache.

Fix this by freeing the cache when closing the device for a single device
filesystem. This will ensure that the mount command passed device path is
scanned successfully during the next mount.

4863f46dda spi: dw: Fix wrong FIFO level setting for long xfers
[ Upstream commit c63b8fd14a7db719f8252038a790638728c4eb66 ]

Due to using the u16 type in the min_t() macros the SPI transfer length
will be cast to word before participating in the conditional statement
implied by the macro. Thus if the transfer length is greater than 64KB the
Tx/Rx FIFO threshold level value will be determined by the leftover of the
truncated after the type-case length. In the worst case it will cause the
dramatical performance drop due to the "Tx FIFO Empty" or "Rx FIFO Full"
interrupts triggered on each xfer word sent/received to/from the bus.

The problem can be easily fixed by specifying the unsigned int type in the
min_t() macros thus preventing the possible data loss.

This loop accidentally reuses the "i" iterator for both the inside and

chip->rmh.stat_len is in the 2-12 range.  If the value of .stat_len is
4 or more then it will loop exactly one time, but if it's less then it
is a forever loop.

896bd85688 net: mscc: ocelot: fix VCAP filters not matching on MAC with "protocol 802.1Q"
[ Upstream commit f964f8399df29d3e3ced77177cf35131cd2491bf ]

Alternative short title: don't instruct the hardware to match on
EtherType with "protocol 802.1Q" flower filters. It doesn't work for the
reasons detailed below.

With a command such as the following:

tc filter add dev $swp1 ingress chain $(IS1 2) pref 3 \
	protocol 802.1Q flower skip_sw vlan_id 200 src_mac $h1_mac \
	action vlan modify id 300 \
	action goto chain $(IS2 0 0)

the created filter is set by ocelot_flower_parse_key() to be of type
OCELOT_VCAP_KEY_ETYPE, and etype is set to {value=0x8100, mask=0xffff}.
This gets propagated all the way to is1_entry_set() which commits it to
hardware (the VCAP_IS1_HK_ETYPE field of the key). Compare this to the
case where src_mac isn't specified - the key type is OCELOT_VCAP_KEY_ANY,
and is1_entry_set() doesn't populate VCAP_IS1_HK_ETYPE.

The problem is that for VLAN-tagged frames, the hardware interprets the
ETYPE field as holding the encapsulated VLAN protocol. So the above
filter will only match those packets which have an encapsulated protocol
of 0x8100, rather than all packets with VLAN ID 200 and the given src_mac.

The reason why this is allowed to occur is because, although we have a
block of code in ocelot_flower_parse_key() which sets "match_protocol"
to false when VLAN keys are present, that code executes too late.
There is another block of code, which executes for Ethernet addresses,
and has a "goto finished_key_parsing" and skips the VLAN header parsing.
By skipping it, "match_protocol" remains with the value it was
initialized with, i.e. "true", and "proto" is set to f->common.protocol,
or 0x8100.

The concept of ignoring some keys rather than erroring out when they are
present but can't be offloaded is dubious in itself, but is present
since the initial commit fe3490e6107e ("net: mscc: ocelot: Hardware
ofload for tc flower filter"), and it's outside of the scope of this
patch to change that.

The problem was introduced when the driver started to interpret the
flower filter's protocol, and populate the VCAP filter's ETYPE field
based on it.

To fix this, it is sufficient to move the code that parses the VLAN keys
earlier than the "goto finished_key_parsing" instruction. This will
ensure that if we have a flower filter with both VLAN and Ethernet
address keys, it won't match on ETYPE 0x8100, because the VLAN key
parsing sets "match_protocol = false".

1ad4112c9f ice: Do not use WQ_MEM_RECLAIM flag for workqueue
[ Upstream commit 4d159f7884f78b1aacb99b4fc37d1e3cb1194e39 ]

When both ice and the irdma driver are loaded, a warning in
check_flush_dependency is being triggered. This is due to ice driver
workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one
is not.

According to kernel documentation, this flag should be set if the
workqueue will be involved in the kernel's memory reclamation flow.
Since it is not, there is no need for the ice driver's WQ to have this
flag set so remove it.

34a5af788e uapi: add missing ip/ipv6 header dependencies for linux/stddef.h
[ Upstream commit 03702d4d29be4e2510ec80b248dbbde4e57030d9 ]

Since commit 58e0be1ef6118 ("net: use struct_group to copy ip/ipv6
header addresses"), ip and ipv6 headers started to use the __struct_group
definition, which is defined at include/uapi/linux/stddef.h. However,
linux/stddef.h isn't explicitly included in include/uapi/linux/{ip,ipv6}.h,
which breaks build of xskxceiver bpf selftest if you install the uapi
headers in the system:

$ make V=1 xskxceiver -C tools/testing/selftests/bpf
...
make: Entering directory '(...)/tools/testing/selftests/bpf'
gcc -g -O0 -rdynamic -Wall -Werror (...)
In file included from xskxceiver.c:79:
/usr/include/linux/ip.h:103:9: error: expected specifier-qualifier-list before ‘__struct_group’
  103 |         __struct_group(/* no tag */, addrs, /* no attrs */,
      |         ^~~~~~~~~~~~~~
...

Include the missing <linux/stddef.h> dependency in ip.h and do the
same for the ipv6.h header.

[ Upstream commit e632291a2dbce45a24cddeb5fe28fe71d724ba43 ]

The cited commit creates child PKEY interfaces over netlink will
multiple tx and rx queues, but some devices doesn't support more than 1
tx and 1 rx queues. This causes to a crash when traffic is sent over the
PKEY interface due to the parent having a single queue but the child
having multiple queues.

This patch fixes the number of queues to 1 for legacy IPoIB at the
earliest possible point in time.

bc9771cd63 can: j1939: do not wait 250 ms if the same addr was already claimed
commit 4ae5e1e97c44f4654516c1d41591a462ed62fa7b upstream.

The ISO 11783-5 standard, in "4.5.2 - Address claim requirements", states:
  d) No CF shall begin, or resume, transmission on the network until 250
     ms after it has successfully claimed an address except when
     responding to a request for address-claimed.

But "Figure 6" and "Figure 7" in "4.5.4.2 - Address-claim
prioritization" show that the CF begins the transmission after 250 ms
from the first AC (address-claimed) message even if it sends another AC
message during that time window to resolve the address contention with
another CF.

As stated in "4.4.2.3 - Address-claimed message":
  In order to successfully claim an address, the CF sending an address
  claimed message shall not receive a contending claim from another CF
  for at least 250 ms.

As stated in "4.4.3.2 - NAME management (NM) message":
  1) A commanding CF can
     d) request that a CF with a specified NAME transmit the address-
        claimed message with its current NAME.
  2) A target CF shall
     d) send an address-claimed message in response to a request for a
        matching NAME

Taking the above arguments into account, the 250 ms wait is requested
only during network initialization.

Do not restart the timer on AC message if both the NAME and the address
match and so if the address has already been claimed (timer has expired)
or the AC message has been sent to resolve the contention with another
CF (timer is still running).

edaf5c7183 of/address: Return an error when no valid dma-ranges are found
commit f6933c01e42d2fc83b9133ed755609e4aac6eadd upstream.

Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range")
converted the parsing of dma-range properties to use code shared with the
PCI range parser. The intent was to introduce no functional changes however
in the case where we fail to translate the first resource instead of
returning -EINVAL the new code we return 0. Restore the previous behaviour
by returning an error if we find no valid ranges, the original code only
handled the first range but subsequently support for parsing all supplied
ranges was added.

This avoids confusing code using the parsed ranges which doesn't expect to
successfully parse ranges but have only a list terminator returned, this
fixes breakage with so far as I can tell all DMA for on SoC devices on the
Socionext Synquacer platform which has a firmware supplied DT. A bisect
identified the original conversion as triggering the issues there.

b7d5fa8052 tracing: Fix poll() and select() do not work on per_cpu trace_pipe and trace_pipe_raw
commit 3e46d910d8acf94e5360126593b68bf4fee4c4a1 upstream.

poll() and select() on per_cpu trace_pipe and trace_pipe_raw do not work
since kernel 6.1-rc6. This issue is seen after the commit
42fb0a1e84ff525ebe560e2baf9451ab69127e2b ("tracing/ring-buffer: Have
polling block on watermark").

This issue is firstly detected and reported, when testing the CXL error
events in the rasdaemon and also erified using the test application for poll()
and select().

This issue occurs for the per_cpu case, when calling the ring_buffer_poll_wait(),
in kernel/trace/ring_buffer.c, with the buffer_percent > 0 and then wait until the
percentage of pages are available. The default value set for the buffer_percent is 50
in the kernel/trace/trace.c.

As a fix, allow userspace application could set buffer_percent as 0 through
the buffer_percent_fops, so that the task will wake up as soon as data is added
to any of the specific cpu buffer.

f1fd16cd97 btrfs: zlib: zero-initialize zlib workspace
commit eadd7deca0ad8a83edb2b894d8326c78e78635d6 upstream.

KMSAN reports uses of uninitialized memory in zlib's longest_match()
called on memory originating from zlib_alloc_workspace().
This issue is known by zlib maintainers and is claimed to be harmless,
but to be on the safe side we'd better initialize the memory.

a1406d5aa3 btrfs: limit device extents to the device size
commit 3c538de0f2a74d50aff7278c092f88ae59cee688 upstream.

There was a recent regression in btrfs/177 that started happening with
the size class patches ("btrfs: introduce size class to block group
allocator").  This however isn't a regression introduced by those
patches, but rather the bug was uncovered by a change in behavior in
these patches.  The patches triggered more chunk allocations in the
^free-space-tree case, which uncovered a race with device shrink.

The problem is we will set the device total size to the new size, and
use this to find a hole for a device extent.  However during shrink we
may have device extents allocated past this range, so we could
potentially find a hole in a range past our new shrink size.  We don't
actually limit our found extent to the device size anywhere, we assume
that we will not find a hole past our device size.  This isn't true with
shrink as we're relocating block groups and thus creating holes past the
device size.

Fix this by making sure we do not search past the new device size, and
if we wander into any device extents that start after our device size
simply break from the loop and use whatever hole we've already found.

dbe5a11954 migrate: hugetlb: check for hugetlb shared PMD in node migration
[ Upstream commit 73bdf65ea74857d7fb2ec3067a3cec0e261b1462 ]

migrate_pages/mempolicy semantics state that CAP_SYS_NICE is required to
move pages shared with another process to a different node.  page_mapcount
> 1 is being used to determine if a hugetlb page is shared.  However, a
hugetlb page will have a mapcount of 1 if mapped by multiple processes via
a shared PMD.  As a result, hugetlb pages shared by multiple processes and
mapped with a shared PMD can be moved by a process without CAP_SYS_NICE.

To fix, check for a shared PMD if mapcount is 1.  If a shared PMD is found
consider the page shared.

97a5104d64 mm/migration: return errno when isolate_huge_page failed
[ Upstream commit 7ce82f4c3f3ead13a9d9498768e3b1a79975c4d8 ]

We might fail to isolate huge page due to e.g.  the page is under
migration which cleared HPageMigratable.  We should return errno in this
case rather than always return 1 which could confuse the user, i.e.  the
caller might think all of the memory is migrated while the hugetlb page is
left behind.  We make the prototype of isolate_huge_page consistent with
isolate_lru_page as suggested by Huang Ying and rename isolate_huge_page
to isolate_hugetlb as suggested by Muchun to improve the readability.
