The upgrade of the cookie authentication algorithm to HMAC-SHA256 kept
some backwards compatibility for the net.sctp.cookie_hmac_alg sysctl by
still accepting the values 'md5' and 'sha1'. Those algorithms are no
longer actually used, but rather those values were just treated as
requests to enable cookie authentication.
As requested at
https://lore.kernel.org/netdev/CADvbK_fmCRARc8VznH8cQa-QKaCOQZ6yFbF=1-VDK=zRqv_cXw@mail.gmail.com/
and https://lore.kernel.org/netdev/20250818084345.708ac796@kernel.org/ ,
go further and start rejecting 'md5' and 'sha1' completely.

Convert SCTP cookies to use HMAC-SHA256, instead of the previous choice
of the legacy algorithms HMAC-MD5 and HMAC-SHA1. Simplify and optimize
the code by using the HMAC-SHA256 library instead of crypto_shash, and
by preparing the HMAC key when it is generated instead of per-operation.
This doesn't break compatibility, since the cookie format is an
implementation detail, not part of the SCTP protocol itself.
Note that the cookie size doesn't change either. The HMAC field was
already 32 bytes, even though previously at most 20 bytes were actually
compared. 32 bytes exactly fits an untruncated HMAC-SHA256 value. So,
although we could safely truncate the MAC to something slightly shorter,
for now just keep the cookie size the same.
I also considered SipHash, but that would generate only 8-byte MACs. An
8-byte MAC *might* suffice here. However, there's quite a lot of
information in the SCTP cookies: more than in TCP SYN cookies. So
absent an analysis that occasional forgeries of all that information is
okay in SCTP, I errored on the side of caution.
Remove HMAC-MD5 and HMAC-SHA1 as options, since the new HMAC-SHA256
option is just better. It's faster as well as more secure. For
example, benchmarking on x86_64, cookie authentication is now nearly 3x
as fast as the previous default choice and implementation of HMAC-MD5.
Also just make the kernel always support cookie authentication if SCTP
is supported at all, rather than making it optional in the build. (It
was sort of optional before, but it didn't really work properly. E.g.,
a kernel with CONFIG_SCTP_COOKIE_HMAC_MD5=n still supported HMAC-MD5
cookie authentication if CONFIG_CRYPTO_HMAC and CONFIG_CRYPTO_MD5
happened to be enabled in the kconfig for other reasons.)

The current consumer documentation does not include bulk operations,
providing an example of how to acquire multiple regulators by calling
regulator_get() multiple times. That solution is valid and slightly
simpler for a small amount of regulators, but it does not scale well.
Document the bulk operations to get, enable and disable regulators.

To handle such cases, use the reset controller framework along with the

Introduce a generic netlink multicast event to report binder transaction
failures to userspace. This allows subscribers to monitor these events
and take appropriate actions, such as stopping a misbehaving application
that is spamming a service with huge amount of transactions.
The multicast event contains full details of the failed transactions,
including the sender/target PIDs, payload size and specific error code.
This interface is defined using a YAML spec, from which the UAPI and
kernel headers and source are auto-generated.

There are other tools which lead to patches of similarly low value

but fixing them in the existing code base is a waste of review time.

The RTL8211F PHY has two modes for a single INTB/PMEB pin:
1. INTB mode, where it signals interrupts to the CPU, which can
include wake-on-LAN events.
2. PMEB mode, where it only signals a wake-on-LAN event, which
may either be a latched logic low until software manually
clears the WoL state, or pulsed mode.
In the case of (1), there is no way to know whether the interrupt to
which the PHY is connected is capable of waking the system. In the
case of (2), there would be no interrupt property in the PHY's DT
description, and thus there is nothing to describe whether the pin is
even wired to anything such as a power management controller.
There is a "wakeup-source" property which can be applied to any device
- see Documentation/devicetree/bindings/power/wakeup-source.txt
Case 1 above matches example 2 in this document, and case 2 above
matches example 3. Therefore, it seems reasonable to make use of this
existing specification, albiet it hasn't been converted to YAML.
Document the wakeup-source property in the device description, which
will indicate that the PHY has been wired up in such a way that it
can wake the system from a low power state.
We will use this in a rewrite of the existing broken Wake-on-Lan code
that was merged during the 6.16 merge window to support case 1. Case 2
can be added to the driver later without needing to further alter the
DT description. To be clear, the existing Wake-on-Lan code that was
recently merged has multiple functional issues.

This allows naming the GPIOs, which is already done in several
device trees (e.g. mt8183-kukui-jacuzzi.dtsi, mt8183-kukui-kakadu.dtsi,
mt8183-kukui-krane.dtsi), but was previously generating DT schema
warnings.

This patch corrects two minor spelling issues found in
Documentation/userspace-api/iommufd.rst:
- "primarly" -> "primarily"
- "sharable" -> "shareable"
Found using codespell(1).

Even though it is referenced by mmc/mmc-controller.yaml it still raises
the warning:
esdhc@1560000 (fsl,ls1021a-esdhc): Unevaluated properties are not allowed ('bus-width' was unexpected)
Adding an explicit reference fixes this.

Pull x86 fixes from Borislav Petkov:
- Remove a transitional asm/cpuid.h header which was added only as a
fallback during cpuid helpers reorg
- Initialize reserved fields in the SVSM page validation calls
structure to zero in order to allow for future structure extensions
- Have the sev-guest driver's buffers used in encryption operations be
in linear mapping space as the encryption operation can be offloaded
to an accelerator
- Have a read-only MSR write when in an AMD SNP guest trap to the
hypervisor as it is usually done. This makes the guest user
experience better by simply raising a #GP instead of terminating said
guest
- Do not output AVX512 elapsed time for kernel threads because the data
is wrong and fix a NULL pointer dereferencing in the process
- Adjust the SRSO mitigation selection to the new attack vectors
* tag 'x86_urgent_for_v6.17_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:

The text was presenting the team, the the e-mail address, then some of
the expectations, then what form of e-mail is expected. By switching
the e-mail paragraph two paragraphs later and dropping the "Contact"
sub-section, we can have a more natural flow that presents the team,
then its expectation, then how to best contribute, then where to send.
And more importantly, it increases the chances that reporters have read
the prerequisites before finding the e-mail address.

Some bug reports sent to the security team sometimes lack any explanation,
are only AI-generated without verification, or sometimes it can simply be
difficult to have a conversation with an invisible reporter belonging to
an opaque team. This fortunately remains rare but the trend has been
steadily increasing over the last years and it seems important to clarify
what developers expect from reporters to avoid frustration on any side and
keep the process efficient.

The ROHM BD79105 is a simple, 16-bit, 1-channel ADC with a 'CONVSTART'
pin used to start the ADC conversion. Other than the 'CONVSTART', there
are 3 supply pins (one used as a reference), analog inputs, ground and
communication pins. It's worth noting that the pin somewhat confusingly
labeled as 'DIN', is a pin which should be used as a chip-select. The IC
does not have any writable registers.
The device is designed so that the output pin can, in addition to
outputting the data, be used as a 'data-ready'-IRQ. There are cases
where the IRQ can't be used (because it is delivered via SPI data-line).
Hence, some systems may use a GPIO for polling the data readiness.
Add a compatible for the bd79105 and add the data-ready GPIO to the
binding.
