ethtool_set_coalesce() now uses both the .get_coalesce() and
.set_coalesce() callbacks. But the check for their availability is
buggy, so changing the coalesce settings on a device where the driver
provides only _one_ of the callbacks results in a NULL pointer
dereference instead of an -EOPNOTSUPP.
Fix the condition so that the availability of both callbacks is
ensured. This also matches the netlink code.
Note that reproducing this requires some effort - it only affects the
legacy ioctl path, and needs a specific combination of driver options:
- have .get_coalesce() and .coalesce_supported but no
.set_coalesce(), or
- have .set_coalesce() but no .get_coalesce(). Here eg. ethtool doesn't
cause the crash as it first attempts to call ethtool_get_coalesce()
and bails out on error.

Merge fix and cleanup related to the management of ACPI device

ACPI: Get acpi_device's parent from the parent field
The Tx queues were not disabled in situations where the driver needed to
stop the interface to apply a new configuration. This could result in a
kernel panic when doing any of the 3 following actions:
* reconfiguring the number of queues (ethtool -L)
* reconfiguring the size of the ring buffers (ethtool -G)
* installing/removing an XDP program (ip l set dev ethX xdp)
Prevent the panic by making sure netif_tx_disable is called when stopping
an interface.
Without this patch, the following kernel panic can be observed when doing
any of the actions above:
Unable to handle kernel paging request at virtual address ffff80001238d040

[BUG]
Fstests generic/027 is pretty easy to trigger a slow but steady memory
leak if run with "-o compress=lzo" mount option.
Normally one single run of generic/027 is enough to eat up at least 4G ram.
[CAUSE]
In commit d4088803f5 ("btrfs: subpage: make lzo_compress_pages()
compatible") we changed how @page_in is released.
But that refactoring makes @page_in only released after all pages being
compressed.
This leaves error path not releasing @page_in. And by "error path"
things like incompressible data will also be treated as an error
(-E2BIG).
Thus it can cause a memory leak if even nothing wrong happened.
[FIX]
Add check under @out label to release @page_in when needed, so when we
hit any error, the input page is properly released.

tls: splice_read fixes
As I work my way to unlocked and zero-copy TLS Rx the obvious bugs
in the splice_read implementation get harder and harder to ignore.
This is to say the fixes here are discovered by code inspection,
I'm not aware of anyone actually using splice_read.

Previous patch fixes overriding callbacks incorrectly. Triggering
the crash in sendpage_locked would be more spectacular but it's
hard to get to, so take the easier path of proving this is broken
and call getname. We're currently getting IPv4 socket info on an
IPv6 socket.
Signed-off-by: Jakub Kicinski <kuba@kernel.org>
We replace proto_ops whenever TLS is configured for RX. But our
replacement also overrides sendpage_locked, which will crash
unless TX is also configured. Similarly we plug both of those
in for TLS_HW (NIC crypto offload) even tho TLS_HW has a completely
different implementation for TX.
Last but not least we always plug in something based on inet_stream_ops
even though a few of the callbacks differ for IPv6 (getname, release,
bind).
Use a callback building method similar to what we do for struct proto.

recvmsg() will put peek()ed and partially read records onto the rx_list.
splice_read() needs to consult that list otherwise it may miss data.
Align with recvmsg() and also put partially-read records onto rx_list.
tls_sw_advance_skb() is pretty pointless now and will be removed in
net-next.

Signed-off-by: Jakub Kicinski <kuba@kernel.org>
We don't support splicing control records. TLS 1.3 changes moved
the record type check into the decrypt if(). The skb may already
be decrypted and still be an alert.
Note that decrypt_skb_update() is idempotent and updates ctx->decrypted
so the if() is pointless.
Reorder the check for decryption errors with the content type check
while touching them. This part is not really a bug, because if
decryption failed in TLS 1.3 content type will be DATA, and for
TLS 1.2 it will be correct. Nevertheless its strange to touch output
before checking if the function has failed.

There are only a few devicetree fixes this time:
- one outdated devicetree property that slipped into the
newly added ExynosAutov9 support
- three changes to Broadcom SoCs that had incorrect
number values for interrupts or irqchips.
In the MAINTAINERS file, Nishanth Menon gets listed for TI K3 SoCs,
while Taichi Sugaya and Takao Orito take ownership of the Socionext
Milbeaut platform.
All other changes are for SoC specific drivers, fixing:

- An integer overflow issue in the Arm smccc firwmare interface
- A false-positive fortify-source check
- Error handling fixes for optee and smci
- Incorrect message format in one SCMI call

Merge tag 'folio-5.16b' of git://git.infradead.org/users/willy/pagecache
Pull folio fixes from Matthew Wilcox:
"In the course of preparing the folio changes for iomap for next merge
window, we discovered some problems that would be nice to address now:
- Renaming multi-page folios to large folios.
mapping_multi_page_folio_support() is just a little too long, so we
settled on mapping_large_folio_support(). That meant renaming, eg
folio_test_multi() to folio_test_large().
Rename AS_THP_SUPPORT to match
- I hadn't included folio wrappers for zero_user_segments(), etc.
Also, multi-page^W^W large folio support is now independent of
CONFIG_TRANSPARENT_HUGEPAGE, so machines with HIGHMEM always need
to fall back to the out-of-line zero_user_segments().
Remove FS_THP_SUPPORT to match
- The build bots finally got round to telling me that I missed a
couple of architectures when adding flush_dcache_folio(). Christoph
suggested that we just add linux/cacheflush.h and not rely on
asm-generic/cacheflush.h"

The issue happened randomly in runtime. The message "Link is Down" is
popped but soon it recovered to "Link is Up".
The "Link is Down" results from the incorrect read data for reading the
PHY register via MDIO bus. The correct sequence for reading the data
shall be:
1. fire the command
2. wait for command done (this step was missing)
3. wait for data idle
4. read data from data register

Danielle brought this back up as still occurring, so we'll try
again.

As Alex suggested, change the driver to return work_done at the
exit of napi_poll, which should be safe to do in this driver
because it is not polling multiple queues in this single napi
context (multiple queues attached to one MSI-X vector). Several
other drivers contain the same simple sequence, so I hope
this will not create new problems.

The kernel_listen function in smc_listen will fail when all the available
ports are occupied. At this point smc->clcsock->sk->sk_data_ready has
been changed to smc_clcsock_data_ready. When we call smc_listen again,
now both smc->clcsock->sk->sk_data_ready and smc->clcsk_data_ready point
to the smc_clcsock_data_ready function.
The smc_clcsock_data_ready() function calls lsmc->clcsk_data_ready which
now points to itself resulting in an infinite loop.
This patch restores smc->clcsock->sk->sk_data_ready with the old value.
