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.

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.

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.

The "Items that don't need to be mentioned in Go 1.23 release notes but

at reviewing that list. The large number of items needed to be reviewed

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.

Also, for the existing atomicAnd/Or operations, the updated
value are not used, but at that time we need a register to

is not needed anymore. This CL changes it.
The other change is that the existing operations don't use their

And this CL alias all of the And/Or operations into sync/atomic

Instead of having testing/internal/testdeps import the
internal/coverage/cfile package directly, have the code in testmain
pass in pointers to cfile functions during setup in the case that
we're running a "go test -cover" binary. This reduces the size of
regular non-coverage test binaries back to what they were before CL
585820.
Updates #67401.
Fixes#67588.

This CL adds a (very opinionated) client-side ECH implementation.
In particular, if a user configures a ECHConfigList, by setting the
Config.EncryptedClientHelloConfigList, but we determine that none of
the configs are appropriate, we will not fallback to plaintext SNI, and
will instead return an error. It is then up to the user to decide if
they wish to fallback to plaintext themselves (by removing the config
list).
Additionally if Config.EncryptedClientHelloConfigList is provided, we
will not offer TLS support lower than 1.3, since negotiating any other
version, while offering ECH, is a hard error anyway. Similarly, if a
user wishes to fallback to plaintext SNI by using 1.2, they may do so
by removing the config list.
With regard to PSK GREASE, we match the boringssl behavior, which does
not include PSK identities/binders in the outer hello when doing ECH.
If the server rejects ECH, we will return a ECHRejectionError error,
which, if provided by the server, will contain a ECHConfigList in the
RetryConfigList field containing configs that should be used if the user
wishes to retry. It is up to the user to replace their existing
Config.EncryptedClientHelloConfigList with the retry config list.
Fixes#63369
