f26befb380 net: avoid wrapping io.EOF in UnixConn read methods 
The io.Reader contract requires that Read methods return io.EOF
directly instead of wrapping it in another error.

Currently UnixConn.ReadFromUnix, ReadFrom, and ReadMsgUnix wrap
io.EOF inside net.OpError, causing callers checking for io.EOF
to fail.

Fix by avoiding wrapping when err == io.EOF.

Fixes #78137

4b7b1be731 cmd/internal/objabi: implement GCC-compatible response file parsing 
Replace line-based response file parsing with GCC-compatible one
that supports:
- Whitespace-delimited arguments (multiple args per line)
- Single quotes for literal content (no escape processing)
- Double quotes with escape sequences: \\, \", \$, \`
- Backslash-newline line continuation (both LF and CRLF)

Update encodeArg in cmd/go/internal/work to produce GCC-compatible
output with proper escaping of special characters.

Add response file support to cmd/pack.

3694f33692 runtime: GODEBUG=tracebacklabels=1 for 1.27+ 
https://go.dev/cl/742580 updated the goroutine label format in
tracebacks to only quote the values under some circumstances, and use a
more broadly acceptable format. Flip the GODEBUG=tracebacklabels default
for go 1.27+ modules.

Notably, tracebacklabels is marked as Opaque to avoid some diciness in
maintaining a usage metric in signal handlers, etc. (where mutex
acquisition may be problematic)

Also, update the go 1.27 release notes to call out the new feature.

Updates #76349

2b8dbb35b0 crypto,testing/cryptotest: ignore random io.Reader params, add SetGlobalRandom 
First, we centralize all random bytes generation through drbg.Read. The
rest of the FIPS 140-3 module can't use external functions anyway, so
drbg.Read needs to have all the logic.

Then, make sure that the crypto/... tree uses drbg.Read (or the new
crypto/internal/rand.Reader wrapper) instead of crypto/rand, so it is
unaffected by applications setting crypto/rand.Reader.

Next, pass all unspecified random io.Reader parameters through the new
crypto/internal/rand.CustomReader, which just redirects to drbg.Read
unless GODEBUG=cryptocustomrand=1 is set. Move all the calls to
MaybeReadByte there, since it's only needed for these custom Readers.

Finally, add testing/cryptotest.SetGlobalRandom which sets
crypto/rand.Reader to a locked deterministic source and overrides
drbg.Read. This way SetGlobalRandom should affect all cryptographic
randomness in the standard library.

Fixes #70942

a3fb92a710 runtime/secret: implement new secret package 
Implement secret.Do.

- When secret.Do returns:
  - Clear stack that is used by the argument function.
  - Clear all the registers that might contain secrets.
- On stack growth in secret mode, clear the old stack.
- When objects are allocated in secret mode, mark them and then zero
  the marked objects immediately when they are freed.
- If the argument function panics, raise that panic as if it originated
  from secret.Do. This removes anything about the secret function
  from tracebacks.

For now, this is only implemented on linux for arm64 and amd64.

This is a rebased version of Keith Randalls initial implementation at
CL 600635. I have added arm64 support, signal handling, preemption
handling and dealt with vDSOs spilling into system stacks.

These methods have been introduced into the reflect package (as well
as tests) replacing three-clause for loops where possible.

4fb7e083a8 crypto/tls: expose HelloRetryRequest state 
This commit adds fields to the ClientHelloInfo and ConnectionState
structures to represent hello retry request state information.

ClientHelloInfo gains a new HelloRetryRequest bool field that indicates
if the client hello was sent in response to a TLS 1.3 hello retry
request message previously emitted by the server.

ConnectionState gains a new HelloRetryRequest bool field that indicates
(depending on the connection role) whether the client received a TLS 1.3
hello retry request message from the server, or whether the server sent
such a message to a client.

Fixes #74425

c1b7112af8 os/signal: make NotifyContext cancel the context with a cause 
This is especially useful when combined with the nesting semantics of
context.Cause, and with errgroup's use of CancelCauseFunc.

For example, with the following code

	ctx, stop := signal.NotifyContext(context.Background(), os.Interrupt)
	defer stop()
	serveGroup, ctx := errgroup.WithContext(ctx)

calling context.Cause(ctx) after serveGroup.Wait() will return either
"interrupt signal received" (if that happens first) or the error from
serveGroup.

a087dea869 debug/elf: sync new loong64 relocation types up to LoongArch ELF psABI v20250521 
Add several new relocation types defined in newer versions of LoongArch
ELF psABI v20250521, part of the v2.40 spec bundle. The new relocations
are seeing increased adoption because distributions are moving to newer
GNU/LLVM toolchain versions, so Go's internal linker must be prepared to
handle some of them, especially R_LARCH_CALL36 because the ecosystem is
slowly migrating to the "medium" code model by default.

The constants R_LARCH_DELETE and R_LARCH_CFA were removed in LoongArch
ELF psABI v20231102 (spec bundle v2.20), but they are already part of
the public API, so they are retained for now for upholding the go1
compatibility guarantee.

Corresponding binutils implementation:

* R_LARCH_CALL36: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=dc5f359ed6a36d2c895d89c3e4886f3a2b6d9232

8e734ec954 go/ast: fix BasicLit.End position for raw strings containing \r 
This CL causes the parser to record in a new field, BasicLit.EndPos,
the actual end position of each literal token, and to use it in
BasicLit.End. Previously, the End was computed heuristically as
Pos + len(Value). This heuristic is incorrect for a multiline
raw string literal on Windows, since the scanner normalizes
\r\n to \n.

Unfortunately the actual end position is not returned by the
Scanner.Scan method, so the scanner and parser conspire
using a global variable in the go/internal/scannerhook
package to communicate.

+ test, api change, relnote
