44d06616b5 doc/next: preannounce a new Linux kernel version requirement
This change adds a preannouncement to the release notes. Go 1.24
will require the Linux kernel to be at version 3.17 or later,
with an exception that systems running 3.10 or later will
continue to be supported if the kernel has been patched to
support the getrandom system call.

For #67001

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.

960cd14124 doc/README: suggest a way to preview next content, tweak release steps
Smaller edits are usually fine to do without previewing, since Markdown

and such, it can be helpful to quickly see the end result. Write down a
way to do that.

Update the release steps to capture that the doc/next content will move
to x/website before RC 1, when the complete release note draft is ready.

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.

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

This also fixes the deprecated Certificate.CreateCRL for RSA-PSS, not

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.

Per the note earlier in the page, GODEBUGs are maintained for a
minimum of two years (four Go releases). Not said but certainly
implied is that they are maintained for four Go releases from the
point where people started needing to use them.

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