b691da9f78 Revert "crypto/x509: reject serial numbers longer than 20 octets"
This reverts commit 8524931a2c.

Reason for revert: It turns out, basically no one in private PKIs can
get this right. It causes way too much breakage, and every other impl
also ignores it, so we'll continue to be in good company.

77cc7fbc84 doc/next: add motivation and details links for range-over-func iterators
The "Changes to the language" section at the top of the release notes
will likely ultimately include more explanation about iterators, or at
least, the Go project will likely publish additional introductory
material on iterators on the blog and so on.

As a perhaps temporary step given current interest, this CL updates the
release notes with two additional links for details and motivation.

The new package documentation for the iter package is up-to-date,
precise, and also more accessible than the language spec, while the 2022
pre-proposal GitHub discussion starts with perhaps the most compelling
motivation writeup so far. (We purposefully include "2022" in the text
to help illustrate this was not the result of an overly hasty process).

We also update the target of the existing language spec reference to be
closer to the new material.

For #61405.

The language change for the accepted range-over-func proposal #61405
was documented in CL 590616. Remove the corresponding 'TODO' entry.

Also improve formatting slightly, and switch to preferred relative

While here, also simplify the suggested line to preview release notes
locally: setting the -content='' flag explicitly is no longer required
as of CL 589936.

Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum

regression on applications where that is (or became) the bottleneck.

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.

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

That notice is removed when the final release (go1.N.0) is made.
For example, the last time was in CL 562255.

Add this to the Go 1.23 draft and to the future fragment template.

Also switch to the main pkg.go.dev instance and use a relative issue

c96159c252 crypto/x509: cleanup signature generation
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.

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.

6ccd8e4cf6 cmd/go: add support for godebug lines in go.mod and go.work
The fact that the go line sets both the language version and the
GODEBUG compatibility version can be a problem, especially since
the go line is also required to be ≥ the go lines of any required
dependency modules.

This change adds a new 'godebug' line to go.mod and go.work
to allow setting the GODEBUG values for the entire module.

It also adds a new meta-value default=go1.21 that means
take the defaults from Go 1.21 no matter what the go line says.

These were discussed in proposal #65573.

Fixes #65573.

Since people would start needing gotypesalias=0 in Go 1.23,
it can be removed in Go 1.27.

Additionally, the internal representation of a cookie in the cookiejar
package has been adjusted to align with the new representation.

84fbdf01ff cmd/go: use cache for PGO preprocessing
This is the final CL in the series adding PGO preprocessing support to
cmd/go. Now that the tool is hooked up, we integrate with the build
cache to cache the result.

This is fairly straightforward. One difference is that the compile and
link do caching through updateBuildID. However, preprocessed PGO files
don't have a build ID, so it doesn't make much sense to hack our way
through that function when it is simple to just add to the cache
ourselves.

As as aside, we could add a build ID to the preproccessed file format,
though it is not clear if it is worthwhile. The one place a build ID
could be used is in buildActionID, which currently compute the file hash
of the preprocessed profile. With a build ID it could simply read the
build ID. This would save one complete read of the file per build
(cmd/go caches the hash), but each compile process also reads the entire
file, so this is a small change overall.

Fixes #58102.

1843464f01 all: consistently use "IEEE 754" over "IEEE-754"
There is no hyphen between the organization and the number.

For example, https://standards.ieee.org/ieee/754/6210/
shows the string "IEEE 754-2019" and not "IEEE-754-2019".

This assists in searching for "IEEE 754" in documentation
and not missing those using "IEEE-754".

890179d949 misc/wasm: drop wasmtime < 14 support
For Go 1.23, we decided to no longer support the old CLI interface
exposed by wasmtime. This removes the extra logic included to support
both the new and the old CLI interface. Now only versions of wasmtime
14 and newer are supported.

Fixes #63718

5d29578fd5 testing: add TB.SetGOMAXPROCS function
Add a new method TB.SetGOMAXPROCS which sets variable of GOMAXPROCS.
This method aims to set a variable for the isolated lifetime of the test and cleans up.
And unset this when the test ends.
This method disables the test or benchmark from running in
parallel.

Fixes: #62020
