3f4be127bc Revert "runtime: use semaphore structure for futex locks"
This reverts commit dfb7073bb8 (CL 585636).

Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum
throughput of contended runtime.mutex values, and causing a performance
regression on applications where that is (or became) the bottleneck.

This reverts commit f9ba2cff22 (CL 586237)

Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum
throughput of contended runtime.mutex values, and causing a performance
regression on applications where that is (or became) the bottleneck.

This test verifies that the semantics of the mutex profile for
runtime.mutex values matches that of sync.Mutex values. Without the rest
of the patch series, this test would correctly identify that Go 1.22's
semantics are incorrect (issue #66999).

787414ca48 cmd/cgo/internal/swig: force use of lld for LTO tests on the builders
For whatever reason, on the builders, when using /usr/bin/ld (the
default linker) with -flto we end up with problems. Specifically, the
linker seems to require LLVMgold.so and can't find it. I'm not really
sure why, but what definitely seems to work is forcing use of lld, which
ships with our clang installation on the builders.

Just enforce this on the builders for now; I've actually had very few
problems running this locally (and I think I'm also mixing and matching
linkers and toolchains too...), so it may be related to the version of
clang we're testing with.

This change, along with CL 589295, should fully fix the clang builders.

Fixes #67698.

cad3ed207f cmd/cgo/internal/swig,cmd/go: reenable swig tests on 386
CL 588938 skipped the tests because they were broken to unblock the
builders, but we're fairly certain the reason they were failing is
because we're missing g++-multilib. This change is intended to land once
CL 589175 is deployed.

fa08befb25 cmd/cgo/internal/swig,cmd/go: skip swig tests on 386
We recently added a C++ toolchain to the image, and this is causing
problems on 386 and clang builders. The likely culprit is that we're
missing 32-bit C++ libraries on the builders.

Even if this theory is wrong, these tests *never* ran (always skipped,
or truly never ran) on these platforms, so just skip them for now. We
can look into getting the libraries installed later, but skip for now
to unblock the builders.

There are also problems with clang, but I believe they'll be resolved by
setting CXX to clang++ in golangbuild.

For #67698.

a3a584e4ab os: RemoveAll: fix symlink race for unix
Since all the platforms now support O_DIRECTORY flag for open, it can be
used to (together with O_NOFOLLOW) to ensure we open a directory, thus
eliminating the need to call stat before open. This fixes the symlink race,
when a directory is replaced by a symlink in between stat and open calls.

While at it, rename openFdAt to openDirAt, because this function is (and was)
meant for directories only.

NOTE Solaris supports O_DIRECTORY since before Solaris 11 (which is the
only version Go supports since supported version now), and Illumos
always had it. The only missing piece was O_DIRECTORY flag value, which
is taken from golang.org/x/sys/unix.

Updates #52745.

22a80e78ea syscall: Setrlimit: always clean rlimitNofileCache
Since the introduction of origRlimitNofileCache in CL 476097 the only way to
disable restoring RLIMIT_NOFILE before calling execve syscall
(os.StartProcess etc) is this:

	var r syscall.Rlimit
	syscall.Getrlimit(syscall.RLIMIT_NOFILE, &r)
	syscall.Setrlimit(syscall.RLIMIT_NOFILE, &r)

The problem is, this only works when setrlimit syscall succeeds, which
is not possible in some scenarios.

Let's assume that if a user calls syscall.Setrlimit, they
unconditionally want to disable restoring the original rlimit.

For #66797.

5c7d774538 cmd/link: propagate FromAssembly attribute when cloning symbols to external
When a symbol is cloned to external (in order to edit it),
propagate the FromAssembly attribute, so the linker knows it is
(originally) an assembly symbol, and can treat it specially (e.g.
for stack maps).

This should fix the Linux/RISCV64 builder.

54efef99b2 iter: deflake TestPull by letting exiting goroutines finish
Currently TestPull is flaky because goroutines spawned to run subtests
exit asynchronously when they finish and TestPull has explicit checks
for the number of existing goroutines.

This is pretty much only a problem between subtests executing, because
within each subtest the coroutine goroutine spawned for iter.Pull always
exits fully synchronously before the final `next` or `stop` returns.

So, we can resolve the problem by ensuring the first goroutine count the
test takes likely doesn't contain any exiting goroutines. The trick is
to set GOMAXPROCS=1 and spin in runtime.Gosched until the number of
goroutines stabilizes to some reasonable degree (we pick 100 consecutive
iterations; there are only a handful of possible goroutines that can
run, so this is giving that handful around 20 chances to actually run to
completion).

When running TestPull under stress2, this issue is easily reproducible
before this CL. After this CL, it no longer reproduces under these
conditions.

Fixes #66017.

acc93dac83 doc/next: populate TODOs found with relnote todo
This is the first round of TODOs created based on relnote todo output.
There are many entries that need to be documented, expanded, reworded,
and this change makes progress on setting that up.

For this cycle, relnote todo implemented a simple heuristic of finding
CLs that mention accepted proposals (see issue 62376, or comment
https://go.dev/issue/62376#issuecomment-2101086794 specifically).
The "Items that don't need to be mentioned in Go 1.23 release notes but
are picked up by relnote todo." section in todo.md contains an attempt
at reviewing that list. The large number of items needed to be reviewed
made it impractical to spend much time on any individual one.

For #65614.

3ed007d754 net/http: remove TestTransportDialCancelRace
This test was added to cover a specific race condition
in request cancellation, applying only to the deprecated
Transport.CancelRequest cancellation path. The test
assumes that canceling a request at the moment
persistConn.RoundTrip begins guarantees that it will
be canceled before being sent.

This does not apply to the newer forms of canceling
a request: Request.Cancel and context-based cancellation
both send the cancel signal on a channel, and do not
check for cancellation before sending a request.

A recent refactoring unified the implementation
of cancellation, so the Transport.CancelRequest
path now translates into context-based cancellation
internally. This makes this test flaky, since
sometimes the request completes before we read
from the context's done channel.

Drop the test entirely. It's verifying the fix
for a bug in a code path which no longer exists,
and the property that it's testing for (canceling
a request at a very specific point in the internal
request flow) is not interesting.

Fixes #67533
