ifconfig: Fix handling of unsupported -j option with MK_JAIL=no
The ifconfig(8) utility built with MK_JAIL=no does not support the
-j option. When the option is specified, Perror() is called without
setting errno, which can result in errno being reported as zero and
a misleading error message being displayed.
Also remove "[-j jail]" from the usage message when built with
MK_JAIL=no.

including profile compliance and level checks.
- Support for matmul_t to matmul in the downgrade pass.
Note that MXFP support will be added in a follow-up commit.

xhci: Do not drop and add bits in xhci
Drop and Add bits reset the data toggle for high-speed devices in XHCI.
The toggle bit represents the sequence number in USB 2.0 transfers. However,
a device can only recognize that the toggle bit has been reset while in
the HALT state. As a result, the host and device toggle values may
become mismatched, causing xHCI to reject the packet. This issue was
observed while testing the EZ-USB FX2 device.
The transfer may then return to the original value after a
bi-directional TD because the toggle field is only one bit wide. This
explains the reson that we can only receive packets bi-transfer in some
case. Therefore, we do not reset the toggle bit here.

libc: Use slow path in fenv in C++
C++ exposes cfenv functions via using ::func. Our name-mangling
mechanism rewrites all function calls causing symbols such as
std::feclearexcept to be transformed into std::__feclearexcept_int.
Since no such function exists, compilation fails.
The using ::feclearexpect declarations themselves are unaffected because
they are not function calls, which further exposes the mismatch
As a result, enable the fast path only for C and fall back to the slow
path in C++.

hwpstate_intel: Disable package control on hybrid CPU
In package control mode, the performance of all cores depends on the
most recent value written to the request field. If the last write comes
from an E-core, all cores are forced to align with the E-core
performance level, resulting in significant performance degradation.
Therefore, package control is disabled on hybrid-core systems.

[clang-index][USR] GenLoc prints file entry at most once, allow repeated offsets
GenLoc previously printed the source location at most once per USR,
gated by a member flag toggled on the first call. During the
recursive visit, if both an outer and an inner decl needed to print
the location, only the outer one was printed. When the outer decl did
not need the offset, no offset was ever printed. For example, the USR
of `Holder<decltype([]{})>::method` depends on the location of the
type of the lambda but the outer decl prints the file entry only,
which disables offset printing.
Change the logic so the file-entry part of the location is printed at
most once (it must be identical), while offsets of sub-decl locations
may be printed multiple times.
[docs] Enforce unambiguous toctree in llvm/docs
It seems like using a non-`hidden` `toctree` for page navigation is a
bit of a trap, in that every doc must have a single unique path through
the global toctree to the root doc, and it is very easy to end up with
multiple.
This patch tries to address the warnings (actually infos, hence why it
does not fail the build) in llvm/docs/, namely:
$ sphinx-build -b html -jauto llvm/docs/ /tmp/sphinx-out
checking consistency...

[docs] Create utils/docs
llvm-project is home to many sphinx documentation sites, each with
configuration quirks and bespoke extensions.
The sphinx config model makes sharing code somewhat difficult. There
are options like sphinx-multiproject, but some of our docs builds are
out of the source tree while some are done out of the binary tree, so
the multiproject configuration itself would need to be generated. It
also would impose more uniformity around extensions than required.
This change instead creates a python package at utils/docs/llvm_sphinx
and makes it available to all sphinx-build processes via PYTHONPATH.
Each conf.py does not modify its own sys.path because not all builds are
out of the source tree, so there isn't a stable relative path to use to
refer to the utils/docs/ directory.
Type checking via pyright in new package is pinned to being python 3.8
compatible.

Bump minimum required sphinx Python to 3.8
There seems to be de-facto use of at least 3.6 in docs, namely:
* Use of pathlib (3.4) in various places
* Format f-strings (3.6) and used in clang/docs/ghlinks.py
I don't see a strong reason to maintain the divide in minimum version
between test/docs, especially considering the "FIXME" indicating
the 3.0 lower bound was just a guess to begin with.

NAS-141464 / 27.0.0-BETA.1 / Add SCRAM-PLUS channel binding support (#19166)
Wire up the server side of SCRAM-PLUS (RFC 5929 tls-server-end-point)
channel binding for API-key auth, using the primitives added in
truenas-scram 0.2.0.
- pam_keyring publishes the active UI cert's tls-server-end-point value
as the TRUENAS_SCRAM_PLUS_SERVER_BINDING 'user' key in the uid=0
persistent keyring for pam_truenas to verify against. Idempotent and
best-effort; rotates in place and is cleared when no UI cert is set.
- truenas-api-key.mako passes channel_binding=negotiate, so binding is
honored when offered but never required.
- Regenerate pam on UI-cert redeploy and on a UI-cert switch to keep the
published binding in sync with the served cert.
- ScramPamAuthenticator rejects a client demanding binding (gs2 'p=')
over a non-TLS transport: TLS terminates at nginx, so the binding is
only a hash of the public cert that a cleartext client could replay.
- Bump python3-truenas-scram to >= 0.2.0 and document the behavior in
the AuthSCRAM model.

[dsymutil] Reuse a single thread pool across architectures (#204691)
dsymutil links the architectures of a universal binary on a thread pool,
and the parallel linker's DWARFLinkerImpl::link() then created a second
pool to link each architecture's object files. With one such inner pool
per architecture, dsymutil spun up more worker threads than the machine
has cores.
Add DWARFLinkerBase::setThreadPool() so the caller provides the pool.
The parallel linker schedules the object files on it as a
ThreadPoolTaskGroup. dsymutil hands over the pool it already uses to
schedule the architectures, llvm-dwarfutil passes one sized by
--num-threads, and the classic linker ignores it and manages its own
threads (always 2 for the lockstep algorithm).
The per-compile-unit cloning still runs on the global llvm::parallel
executor, whose per-thread allocators are indexed by getThreadIndex(),
so it can't move onto this pool.

[lldb] Disable dynamic script interpreters by default under Xcode (#205423)
When LLDB_ENABLE_DYNAMIC_SCRIPTINTERPRETERS is set, liblldb's export
list is built by merging the undefined LLDB symbols extracted from each
script interpreter plugin's objects (119e57630281). Because the plugins
link liblldb, the generated file is wired into liblldb's link via
LINK_DEPENDS, a file-level dependency with no target-level edge.
The Xcode generator only has coarse target-level dependencies, so that
generated liblldb-script-interpreter.exports ends up attached to two
targets with no common dependency, which its "new build system" rejects
at generation time:
```
CMake Error in source/API/CMakeLists.txt:
.../source/API/liblldb-script-interpreter.exports
is attached to multiple targets ... but none of these is a common
dependency of the other(s). This is not allowed by the Xcode "new
build system".
