Roxy Light f7b8dd9033 io/fs: add ReadLinkFS interface
Added implementations for *io/fs.subFS, os.DirFS, and testing/fstest.MapFS.
Amended testing/fstest.TestFS to check behavior.

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.

Fixes #49580

Filippo Valsorda c5c4f3dd5f crypto/x509: keep RSA CRT values in ParsePKCS1PrivateKey
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).

Filippo Valsorda 7d7192e54f crypto/rsa: move precomputation to crypto/internal/fips140/rsa
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.

Filippo Valsorda 4b7f7cd87d crypto/tls: implement X25519MLKEM768
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.

deprecated HTTP/2 upgrade mechanism (RFC 7540, section 3.2 "h2c").

For Server, UnencryptedHTTP2 controls whether the server
will accept HTTP/2 connections on unencrypted ports.
When enabled, the server checks new connections for
the HTTP/2 preface and routes them appropriately.

For Transport, enabling UnencryptedHTTP2 and disabling HTTP1
causes http:// requests to be made over unencrypted HTTP/2
connections.

Roland Shoemaker f69711434a crypto/tls: add server-side ECH
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.

Daniel McCarney 6a7733af45 crypto/pbkdf2: init package
This commit imports the x/crypto/pbkdf2 package as described in the
linked proposal. The code is unchanged with the exception of a few
small updates to reflect feedback from the proposal comment period:

* the Key function is made generic over a hash.Hash
* the h function is moved to be the first argument
* keyLen is renamed to keyLength
* an error return is added
* the unit tests were moved to the pbkdf2_test package

Updates #69488

Roland Shoemaker bc1da38c3d crypto/subtle: add DIT closure
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.

qmuntal 60d66e6a86 os/user: support built-in service user accounts on Windows
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.

Aperence 3d4daa38a7 net: enable multipath TCP by default for listeners
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.

Kir Kolyshkin 79ca434ac6 testing: add Chdir
Some tests need to use os.Chdir, but the use is complicated because
 - they must change back to the old working directory;
 - they must not use t.Parallel.

Add Chdir that covers these cases, and sets PWD environment variable
to the new directory for the duration of the test for Unix platforms.
Unify the panic message when t.Parallel is used together with t.Setenv
or t.Chdir.

Add some tests.

Damien Neil 879ace1434 net/http: keep Content-Encoding in Error, add GODEBUG for ServeContent
This reverts the changes to Error from CL 571995, and adds a
GODEBUG controlling the changes to ServeContent/ServeFile/ServeFS.

The change to remove the Content-Encoding header when serving an error
breaks middleware which sets Content-Encoding: gzip and wraps a
ResponseWriter in one which compresses the response body.

This middleware already breaks when ServeContent handles a Range request.
Correct uses of ServeContent which serve pre-compressed content with
a Content-Encoding: gzip header break if we don't remove that header
when serving errors. Therefore, we keep the change to ServeContent/
ServeFile/ServeFS, but we add the ability to disable the new behavior
by setting GODEBUG=httpservecontentkeepheaders=1.

We revert the change to Error, because users who don't want to include
a Content-Encoding header in errors can simply remove the header
themselves, or not add it in the first place.

Fixes #66343

Rhys Hiltner ca7d300509 Revert "runtime: remove GODEBUG=runtimecontentionstacks"
This reverts commit 87e930f728 (CL 585639)

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.

Dmitri Shuralyov 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.

Roland Shoemaker 9eeb627f60 crypto/tls: add ech client support
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

Centralizing some repetitive code, which would have prevented #45990.

This also fixes the deprecated Certificate.CreateCRL for RSA-PSS, not
that anyone cared, probably.

This has two other minor observable behavior changes: MD2 is now treated
as a completely unknown algorithm (why did we even have that!? removing
lets us treat hash == 0 as always meaning no prehash); and we now do the
signature verification self-check for all signing operations.

Felix Geisendörfer 1b9dc3e178 runtime: increase profiling stack depth to 128
The current stack depth limit for alloc, mutex, block, threadcreate and
goroutine profiles of 32 frequently leads to truncated stack traces in
production applications. Increase the limit to 128 which is the same
size used by the execution tracer.

Create internal/profilerecord to define variants of the runtime's
StackRecord, MemProfileRecord and BlockProfileRecord types that can hold
arbitrarily big stack traces. Implement internal profiling APIs based on
these new types and use them for creating protobuf profiles and to act
as shims for the public profiling APIs using the old types.

This will lead to an increase in memory usage for applications that
use the impacted profile types and have stack traces exceeding the
current limit of 32. Those applications will also experience a slight
increase in CPU usage, but this will hopefully soon be mitigated via CL
540476 and 533258 which introduce frame pointer unwinding for the
relevant profile types.

For #43669.
