Previously, only the type value was settable. The proto value is used
internally for choosing the right drivers, so we should expose it. The
other values make sense to expose as well.

major in here, just lots of tiny fixes for reported issues found by
users and some older patches found by some scanning tools. Included in
here are:
- typec fixes found by fuzzers that have decided to finally look at
that device interaction path (i.e. before a driver is bound to a
device).
- typec fixes for issues found by users
- thunderbolt driver fixes for reported problems
- cdns3 driver fixes
- dwc3 driver fixes
- new device quirks added
- usb serial driver fixes for broken devices
- other small driver fixes
All of these have been in linux-next for over a week with no reported

handshake_complete() declares status as unsigned int and
tls_handshake_done() negates that value (-status) before handing
it to the TLS consumer. Consumers match on negative errno
constants -- xs_tls_handshake_done() has
switch (status) {
case 0:
case -EACCES:
case -ETIMEDOUT:
lower_transport->xprt_err = status;
break;
default:
lower_transport->xprt_err = -EACCES;
}
so the API as designed expects callers to pass positive errno
values that the tlshd shim then negates.
Three internal callers in handshake_nl_accept_doit(), the
net-exit drain, and a kunit test follow kernel convention and
pass negative errnos -- -EIO, -ETIMEDOUT, -ETIMEDOUT. The
implicit conversion to unsigned int turns -ETIMEDOUT into
0xFFFFFF92; the subsequent -status in tls_handshake_done()
wraps back to 110, the consumer's switch falls through, and
the xprt reports -EACCES on what should be -ETIMEDOUT or -EIO.
Fix the API rather than the call sites. The natural kernel
convention is negative errno in, negative errno out. Change
handshake_complete() and hp_done to take int status, drop the
negation in tls_handshake_done(), and negate once in
handshake_nl_done_doit() where status arrives from the wire
as an unsigned netlink attribute. The three internal callers
were already correct under that convention and need no change.
At the same wire boundary, declare MAX_ERRNO as the netlink
policy upper bound for HANDSHAKE_A_DONE_STATUS. Attribute
validation rejects out-of-range values before
handshake_nl_done_doit() runs, and negating a bounded u32 there
stays within int range -- closing the UBSAN-visible signed-
integer overflow that an unconstrained u32 would invoke.

This option was never meant to be used in production because it solely
clears the X86_FEATURE kernel-internal representation of what CPUID bits
it has detected and doesn't do any *proper* feature disablement like
clearing CR4.CET in the user shadow stack case, for example.
So remove its documentation so that it doesn't get used in production
and people get silly ideas. It is meant strictly for debugging; and if
a chicken bit for properly disabling a feature is warranted, then that
would need proper enablement.
No functional changes.

The EIC7700 USB requires a USB PHY reset operation; otherwise, the USB
will not work. The reason why the USB driver that was applied can work
properly is that the USB PHY has already been reset in ESWIN's U-Boot.
However, the proper functioning of the USB driver should not be dependent
on the bootloader. Therefore, it is necessary to incorporate the USB PHY
reset signal into the DT bindings.
This patch does not introduce any backward incompatibility since the dts
is not upstream yet. As array of reset operations are used in the driver,
no modifications to the USB controller driver are needed.

As this is a host controller, reference usb-hcd.yaml which then

Pull RISC-V fixes from Paul Walmsley:
"Relatively low-impact fixes. Probably the most notable one is that we
no longer ask the monitor-mode firmware to delegate misaligned access
handling to the kernel by default, since the kernel code needs
significant improvement to match the functionality of the firmware.
This change avoids functional problems at some cost in performance,
but shouldn't affect any system with misaligned access handling in
hardware.
- Disable satp register probing when no5lvl is specified on the
kernel command line
- Fix a CFI-related issue with the misaligned access speed
measurement code
- Reduce the CFI shadow stack size limit from 4GB to 2GB (following
ARM64 GCS)
- Prevent the kernel from requesting delegation of misaligned access
faults unless a new Kconfig option, RISCV_SBI_FWFT_DELEGATE_MISALIGNED,
is enabled. This will depend on CONFIG_NONPORTABLE until the
deficiencies of the kernel misaligned access fixup code are fixed

995998ebde ("x86/sched: Remove SD_ASYM_PACKING from the SMT domain flags")
overhauled asym_packing handling in the scheduler on x86 hybrid
processors with SMT. It removed SD_ASYM_PACKING from the x86 SMT
scheduling domain and made all SMT siblings of a core share the same
priority. As a result, asym_packing operates only across physical
cores, spreading tasks among them and only using idle SMT siblings
once all physical cores are busy.
Fix the documentation to reflect this behavior.

AI tools are increasingly used to assist in bug discovery. While these
tools can identify valid issues, reports that are submitted without
manual verification often lack context, contain speculative impact
assessments, or include unnecessary formatting. Such reports increase
triage effort, waste maintainers' time and may be ignored.
Reports where the reporter has verified the issue and the proposed fix
typically meet quality standards. This documentation outlines specific
requirements for length, formatting, and impact evaluation to reduce
the effort needed to deal with these reports.

The use of automated tools to find bugs in random locations of the kernel
induces a raise of security reports even if most of them should just be
reported as regular bugs. This patch is an attempt at drawing a line
between what qualifies as a security bug and what does not, hoping to
improve the situation and ease decision on the reporter's side.
It defers the enumeration to a new file, threat-model.rst, that tries
to enumerate various classes of issues that are and are not security
bugs. This should permit to more easily update this file for various
subsystem-specific rules without having to revisit the security bug
reporting guide.
