bd2b117c2c crypto/tls: add QUICErrorEvent
Add a new QUICEvent type for reporting errors.
This provides a way to report errors that don't occur as a result of
QUICConn.Start, QUICConn.HandleData, or QUICConn.SendSessionTicket.

Fixes #75108

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

83df0afc4e runtime/trace: add the flight recorder
This change adds the flight recorder to the trace package.
Flight recording is a technique in which trace data is kept
in a circular buffer and can be flushed upon request. The
implementation will be added in follow-up CLs.

The flight recorder has already been implemented inside of the
golang.org/x/exp/trace package. This copies the current implementation
and modifies it to work within the runtime/trace package.

The changes include:

This adds the ability for multiple consumers (both the execution
tracer and the flight recorder) to subscribe to tracing events. This
change allows us to add multiple consumers without making major
modifications to the runtime. Future optimizations are planned
for this functionality.

This removes the use of byte readers from the process that
parses and processes the trace batches.

This modifies the flight recorder to not parse out the trace
clock frequency, since that requires knowledge of the format that's
unfortunate to encode in yet another place. Right now, the trace clock
frequency is considered stable for the lifetime of the program, so just
grab it directly from the runtime.

This change adds an in-band end-of-generation signal to the internal
implementation of runtime.ReadTrace. The internal implementation is
exported via linkname to runtime/trace, so the flight recorder can
identify exactly when a generation has ended. This signal is also useful
for ensuring that subscribers to runtime trace data always see complete
generations, by starting or stopping data streaming only at generation
boundaries.

e6dacf91ff runtime: use cgroup CPU limit to set GOMAXPROCS
This CL adds two related features enabled by default via compatibility
GODEBUGs containermaxprocs and updatemaxprocs.

On Linux, containermaxprocs makes the Go runtime consider cgroup CPU
bandwidth limits (quota/period) when setting GOMAXPROCS. If the cgroup
limit is lower than the number of logical CPUs available, then the
cgroup limit takes precedence.

On all OSes, updatemaxprocs makes the Go runtime periodically
recalculate the default GOMAXPROCS value and update GOMAXPROCS if it has
changed. If GOMAXPROCS is set manually, this update does not occur. This
is intended primarily to detect changes to cgroup limits, but it applies
on all OSes because the CPU affinity mask can change as well.

The runtime only considers the limit in the leaf cgroup (the one that
actually contains the process), caching the CPU limit file
descriptor(s), which are periodically reread for updates. This is a
small departure from the original proposed design. It will not consider
limits of parent cgroups (which may be lower than the leaf), and it will
not detection cgroup migration after process start.

We can consider changing this in the future, but the simpler approach is
less invasive; less risk to packages that have some awareness of runtime
internals. e.g., if the runtime periodically opens new files during
execution, file descriptor leak detection is difficult to implement in a
stable way.

For #73193.
