A previous change [1] was introduced to enable MPTCP by default
for both the clients and servers, based on the discussions [2] in
golang#56539, where MPTCP would be an opt-in for a release or
two, and then would become an opt-out.
This change was not accepted at the time because the support for
a few socket options was missing [3]. Now that this support has been
added [4] and backported to stable versions not to block MPTCP
deployment with Go, it sounds like a good time to reconsider the use
of MPTCP by default.
Instead of enabling MPTCP on both ends by default, as a first step,
it seems safer to change the default behaviour only for the server
side (Listeners). On the server side, the impact is minimal: when
clients don't request to use MPTCP, server applications will create
"plain" TCP sockets within the kernel when connections are accepted,
making the performance impact minimal. This should also ease
experiments where MPTCP is enabled by default on the client side
(Dialer).
The changes in this patch consist of a duplication of the mptcpStatus
enumeration to have both a mptcpStatusDial and a mptcpStatusListen,
where MPTCP is enabled by default in mptcpStatusListen, but disabled
by default in mptcpStatusDial. It is still possible to turn MPTCP support
on and off by using GODEBUG=multipathtcp=1.

Change the rules for how //go:build "file versions" are applied: instead
of considering whether a file version is an upgrade or downgrade from
the -lang version, always use max(fileVersion, go1.21). This prevents
file versions from downgrading the version below go1.21. Before Go 1.21
the //go:build version did not have the meaning of setting the file's
langage version.
This fixes an issue that was appearing in GOPATH builds: Go 1.23.0
started providing -lang versions to the compiler in GOPATH mode (among
other places) which it wasn't doing before, and it set -lang to the
toolchain version (1.23). Because the -lang version was greater than
go1.21, language version used to compile the file would be set to the
//go:build file version. //go:build file versions below 1.21 could cause
files that could previously build to stop building.
For example, take a Go file with a //go:build line specifying go1.10.
If that file used a 1.18 feature, that use would compile fine with a Go
1.22 toolchain. But it would produce an error when compiling with the
1.23.0 toolchain because it set the language version to 1.10 and
disallowed the 1.18 feature. This breaks backwards compatibility: when
the build tag was added, it did not have the meaning of restricting the
language version.

[This is a roll-forward of CL 597255, which had to be rolled back
because it broke the windows-arm64 builder, whose current user display
name is unavailable. This new CL fixes the issue by reintroducing the
historical behavior of falling back to the user name instead of
returning an error].
user.Current is slow on Windows sessions connected to an Active
Directory domain. This is because it uses Windows APIs that do RPC
calls to the domain controller, such as TranslateAccountW and
NetUserGetInfo.
This change speeds up user.Current by using the GetUserNameEx API
instead, which is already optimized for retrieving the current user
name in different formats.
These are the improvements I see with the new implementation:

Currently the first thing Make does it get the abi.Type of its argument,
and uses abi.TypeOf to do it. However, this has a problem for interface
types, since the type of the value stored in the interface value will
bleed through. This is a classic reflection mistake.
Fix this by implementing and using a generic TypeFor which matches
reflect.TypeFor. This gets the type of the type parameter, which is far
less ambiguous and error-prone.

For the moment, Go calls sendfile(2) to transfer at most 4MB at a time
while sendfile(2) actually allows a larger amount of data on one call.
To reduce system calls of sendfile(2) during data copying, we should
specify the number of bytes to copy as large as possible.
This optimization is especially advantageous for bulky file-to-file copies,
it would lead to a performance boost, the magnitude of this performance
increase may not be very exciting, but it can also cut down the CPU overhead
by decreasing the number of system calls.
This is also how we've done in sendfile_windows.go with TransmitFile.

This CL adds support of "library", i.e. c-shared, build mode on
wasip1. When -buildmode=c-shared is set, it builds a Wasm module
that is intended to be used as a library, instead of an executable.
It does not have the _start function. Instead, it has an
_initialize function, which initializes the runtime, but not call
the main function.
This is similar to the c-shared build mode on other platforms. One
difference is that unlike cgo callbacks, where Ms are created on-
demand, on Wasm we have only one M, so we just keep the M (and the
G) for callbacks.

providing -lang versions to the compiler in GOPATH mode (among other
places) which it wasn't doing before.
For example, take a go file with a //go:build line specifying go1.10.
If that file used a 1.18 feature, that use would compile fine with a Go
1.22 toolchain. But, before this change, it would produce an error when
compiling with the 1.23 toolchain because it set the language version to
1.20 and disallowed the 1.18 feature. This breaks backwards
compatibility: when the build tag was added, it did not have the meaning
of restricting the language version.

user.Current is slow on Windows sessions connected to an Active
Directory domain. This is because it uses Windows APIs that do RPC
calls to the domain controller, such as TranslateAccountW and
NetUserGetInfo.
This change speeds up user.Current by using the GetUserNameEx API
instead, which is already optimized for retrieving the current user
name in different formats.
These are the improvements I see with the new implementation:

The syscall.OpenCurrentProcessToken call in user.Current fails
when called from an impersonated thread, as the process token is
normally in that case.
This change ensures that the current thread is not impersonated
when calling OpenCurrentProcessToken, and then restores the
impersonation state, if any.

The trace parser was using an otherwise-unused event argument to hold an
extra goroutine state argument for the GoStatus & GoStatusStack events.
This is needed because the execution tracer just records the "after" for
state transitions, but we want to have both the "before" and "after"
states available in the StateTransition info for the parsed event. When
GoStatusStack was added, the size of the argument array was increased to
still have room for the extra status. However, statuses are currently
only 1 byte, and the status argument is 8 bytes, so there is plenty of
room to pack the "before" and "after" statuses in a single argument. Do
that instead to avoid the need for an extra argument.

1) Factor out handling of receiver from Checker.funcType into
Checker.collectRecv. Analyze the receiver parameter "manually"
without resorting to calling Checker.collectParams.
The code is more straight-forward and error handling is simpler
because constructing the receiver type and variable is all handled
in one function.
2) Change Checker.collectParams to collect parameter names and
corresponding parameter variables, but do not declare them.
Instead return two equal-length slices of parameter names
and variables for later declaration.
3) Streamline Checker.funcType into a sequence of simple steps.
By declaring the receiver and parameters after type parameters,
there is no need for a temporary scope and scope squashing anymore.
4) Simplify Checker.unpackRecv some more: don't strip multiple
*'s from receiver type expression because we don't typecheck
that expression as a whole later (we don't use collectParams
for receiver types anymore). If we have a **T receiver, we
need to use *T (one * stripped) as receiver base type expression
so that we can report an error later.
5) Remove Checker.recvTParamMap and associated machinery as it is
not needed anymore.
6) Remove Scope.Squash/squash as it is not needed anymore.
7) Remove the explicit scope parameter from Checker.collectParams
as it is not needed anymore.
8) Minor adjustments to tests: in some cases, error positions have
shifted slightly (because we don't use Checker.collectParams to
typecheck receivers anymore), and in some cases duplicate errors
don't appear anymore (resolves TODOs).
Fixes#51343.
