Calling syscall.ReadFile and syscall.WriteFile on overlapped handles
always need to be passed a valid *syscall.Overlapped structure, even if
the handle is not added to a IOCP (like the Go runtime poller). Else,
the syscall will fail with ERROR_INVALID_PARAMETER.
We also need to handle ERROR_IO_PENDING errors when the overlapped
handle is not added to the poller, in which case we need to block until
the operation completes.
Previous CLs already added support for overlapped handles to the poller,
mostly to keep track of the file offset independently of the file
pointer (which is not supported for overlapped handles).
Fixed#15388.
Updates #19098.

This required adding a new field to SessionState for TLS 1.0–1.2, since
the key exchange is not repeated on resumption. The additional field is
unfortunately not backwards compatible because current Go versions check
that the encoding has no extra data at the end, but will cause
cross-version tickets to be ignored. Relaxed that so we can add fields
in a backwards compatible way the next time.
For the cipher suite, we check that the session's is still acceptable
per the Config. That would arguably make sense here, too: if a Config
for example requires PQ, we should reject resumptions of connections
that didn't use PQ. However, that only applies to pre-TLS 1.3
connections, since in TLS 1.3 we always do a fresh key exchange on
resumption. Since PQ is the only main differentiator between key
exchanges (aside from off-by-default non-PFS RSA, which are controlled
by the cipher suite in TLS 1.0–1.2) and it's PQ-only, we can skip that
check.

We previously disallowed all non-regular files being embedded. This CL
relaxes the restriction a little: if the GODEBUG embedfollowsymlinks=1

containing them) to be symlinks. The files pointed to by the symlinks
must still be regular files.
This will be used when a Bazel build action executing the Go command is
running in a symlink-based sandbox. It's not something we want to enable
in general for now, so it's behind a GODEBUG.

This adds a new godebug to control whether the runtime applies the
anonymous memory mapping annotations added in https://go.dev/cl/646095.
It is enabled by default.
This has several effects:
* The feature is only enabled by default when the main go.mod has go >=
1.25.
* This feature can be disabled with GODEBUG=decoratemappings=0, or the
equivalents in go.mod or package main. See https://go.dev/doc/godebug.
* As an opaque setting, this option will not appear in runtime/metrics.
* This setting is non-atomic, so it cannot be changed after startup.
I am not 100% sure about my decision for the last two points.
I've made this an opaque setting because it affects every memory mapping
the runtime performs. Thus every mapping would report "non-default
behavior", which doesn't seem useful.
This setting could trivially be atomic and allow changes at run time,
but those changes would only affect future mappings. That seems
confusing and not helpful. On the other hand, going back to annotate or
unannotate every previous mapping when the setting changes is
unwarranted complexity.

This CL adds an enum type, VarKind, that discriminates among
the various kinds of Var, and adds setter/getter methods
for Var's kind field.
Beware: NewVar has a weaker postcondition: the Var objects it
returns are not completely initialized and require a call to
Var.SetKind. This should only affect importers.
No changes are needed to the export data, since the kind can
always be deduced from the context when decoding.

which does a conditional interface upgrade with a fallback, so they

This CL removes the notion of core types from the spec.
Instead of referring to core types, each section that did
so before is reverted to approx. the pre-generics (1.17)
prose, and additional paragraphs cover the type parameter
cases as needed.
The hope is that this makes it easier to read the spec.
When type parameters are involved, the extra prose is
local to the language feature in question and thus more
readily available. When no type parameters are present,
readers do not have to concern themselves with core types.
In contrast to CL 621919, this change is not intended to
loosen the spec in any way and therefore does not change
the language (if the new prose implies otherwise, we will
correct it).
Except for adjustments to compiler error messages
(no mention of core types anymore), no other changes
to the compiler or tools are required.
Future CLs may selectively relax requirements on a language
construct by language construct basis; each such change can
be discussed and proposed independently.

Addressed TODOs in archive/tar and os.CopyFS around symbolic links.
I am deliberately not changing archive/zip in this CL,
since it currently does not resolve symlinks
as part of its filesystem implementation.
I am unsure of the compatibility restrictions on doing so,
so figured it would be better to address independently.
testing/fstest.MapFS now includes resolution of symlinks,
with MapFile.Data storing the symlink data.
The behavior change there seemed less intrusive,
especially given its intended usage in tests,
and it is especially helpful in testing the io/fs function implementations.

and values that contain references while avoiding
the notion of "reference types" which is misleading.
Also, use "predeclared identifier nil" rather than
"predeclared value nil" because it is the identifier
that is predeclared.

Turns out that recomputing them (and qInv in particular) in constant
time is expensive, so let's not throw them away when they are available.
They are much faster to check, so we now do that on precompute.
Also, thanks to the opaque crypto/internal/fips140/rsa.PrivateKey type,
we now have some assurance that the values we use are always ones we
checked.
Recovers most of the performance loss since CL 630516 in the happy path.
Also, since now we always use the CRT, if necessary by running a
throwaway Precompute, which is now cheap if PrecomputedValues is filled
out, we effectively fixed the JSON round-trip slowdown (#59695).

We are severely limited by the crypto/rsa API in a few ways:
- Precompute doesn't return an error, but is the only function allowed
to modify a PrivateKey.
- Clients presumably expect the PrecomputedValues big.Ints to be
populated after Precompute.
- MarshalPKCS1PrivateKey requires the precomputed values, and doesn't
have an error return.
- PrivateKeys with only N, e, and D have worked so far, so they might
have to keep working.
To move precomputation to the FIPS module, we focus on the happy path of
a PrivateKey with two primes where Precompute is called before anything
else, which match ParsePKCS1PrivateKey and GenerateKey.
There is a significant slowdown in the Parse benchmark due to the
constant-time inversion of qInv. This will be addressed in a follow-up
CL that will use (and check) the value in the ASN.1.
Note that the prime product check now moved to checkPrivateKey is broken
(Π should start at 1 not 0) and fixed in CL 632478.

This makes three related changes that work particularly well together
and would require significant extra work to do separately: it replaces
X25519Kyber768Draft00 with X25519MLKEM768, it makes CurvePreferences
ordering crypto/tls-selected, and applies a preference to PQ key
exchange methods over key shares (to mitigate downgrades).
TestHandshakeServerUnsupportedKeyShare was removed because we are not
rejecting unsupported key shares anymore (nor do we select them, and
rejecting them actively is a MAY). It would have been nice to keep the
test to check we still continue successfully, but testClientHelloFailure
is broken in the face of any server-side behavior which requires writing
any other messages back to the client, or reading them.

Adds support for server-side ECH.
We make a couple of implementation decisions that are not completely
in-line with the spec. In particular, we don't enforce that the SNI
matches the ECHConfig public_name, and we implement a hybrid
shared/backend mode (rather than shared or split mode, as described in
Section 7). Both of these match the behavior of BoringSSL.
The hybrid server mode will either act as a shared mode server, where-in
the server accepts "outer" client hellos and unwraps them before
processing the "inner" hello, or accepts bare "inner" hellos initially.
This lets the server operate either transparently as a shared mode
server, or a backend server, in Section 7 terminology. This seems like
the best implementation choice for a TLS library.

Add a new function, WithDataIndependentTiming, which takes a function as
an argument, and encloses it with calls to set/unset the DIT PSTATE bit
on Arm64.
Since DIT is OS thread-local, for the duration of the execution of
WithDataIndependentTiming, we lock the goroutine to the OS thread, using
LockOSThread. For long running operations, this is likely to not be
performant, but we expect this to be tightly scoped around cryptographic
operations that have bounded execution times.
If locking to the OS thread turns out to be too slow, another option is
to add a bit to the g state indicating if a goroutine has DIT enabled,
and then have the scheduler enable/disable DIT when scheduling a g.
Additionally, we add a new GODEBUG, dataindependenttiming, which allows
setting DIT for an entire program. Running a program with
dataindependenttiming=1 enables DIT for the program during
initialization. In an ideal world PSTATE.DIT would be inherited from
the parent thread, so we'd only need to set it in the main thread and
then all subsequent threads would inherit the value. While this does
happen in the Linux kernel [0], it is not the case for darwin [1].
Rather than add complex logic to only set it on darwin for each new
thread, we just unconditionally set it in mstart1 and cgocallbackg1
regardless of the OS. DIT will already impose some overhead, and the
cost of setting the bit is only ~two instructions (CALL, MSR), so it
should be cheap enough.

This re-enables the behavior of CL 536399 (by effectively reverting CL
628955), so now go test -json again includes build output and failures
as JSON rather than text.
However, since this behavior is clearly enough to trip up some build
systems, this CL includes a GODEBUG=gotestjsonbuildtext that can be
set to 1 to revert to the old behavior.
Fixes#70402.
Updates #62067.

Currently, if a test or imported package fails to build during "go
test -json", the build error text will be interleaved with the JSON
output of tests. Furthermore, there’s currently no way to reliably
associate a build error with the test package or packages it affected.
This creates unnecessary friction and complexity in tools that consume
the "go test -json" output.
This CL makes "go test -json" enable JSON reporting of build errors.
It also adds a "FailedBuild" field to the "fail" TestEvent, which
gives the package ID of the package that failed to build and caused
the test to fail.
Using this, CI systems should be able to consume the entire output
stream from "go test -json" in a structured way and easily associate
build failures with test failures during reporting.
Fixes#62067.
Updates #35169.
Updates #37486.

This change introduces AddCleanup to the runtime package. AddCleanup attaches
a cleanup function to an pointer to an object.
The Stop method on Cleanups will be implemented in a followup CL.
AddCleanup is intended to be an incremental improvement over
SetFinalizer and will result in SetFinalizer being deprecated.

Built-in service user accounts should be treated as special cases
of well-known groups and allowed in user.Lookup and user.LookupId.
Namely, these accounts are:
- NT AUTHORITY\SYSTEM (S-1-5-18)
- NT AUTHORITY\LOCAL SERVICE (S-1-5-19)
- NT AUTHORITY\NETWORK SERVICE (S-1-5-20)
See https://learn.microsoft.com/en-us/windows/win32/services/service-user-accounts.
Note that #49509 also mentions S-1-5-17 (NT AUTHORITY\IUSR) as
another well-known group that should be treated as a user. I haven't
found any documentation supporting this claim, and it is not an account
that is used usually, so I'm not adding it for now.
This CL is heavily based on CL 452497.
Fixes#49509

A GODEBUG is actually a security risk here: most programs will start to
ignore errors from Read because they can't happen (which is the intended
behavior), but then if a program is run with GODEBUG=randcrash=0 it will
use a partial buffer in case an error occurs, which may be catastrophic.
Note that the proposal was accepted without the GODEBUG, which was only
added later.
This (partially) reverts CL 608435. I kept the tests.
