math/big: simplify, speed up Karatsuba multiplication
The old Karatsuba implementation only operated on lengths that are
a power of two times a number smaller than karatsubaThreshold.
For example, when karatsubaThreshold = 40, multiplying a pair
of 99-word numbers runs karatsuba on the low 96 (= 39<<2) words
and then has to fix up the answer to include the high 3 words of each.
I suspect this requirement was needed to make the analysis of
how many temporary words to reserve easier, back when the
answer was 3*n and depended on exactly halving the size at
each Karatsuba step.
Now that we have the more flexible temporary allocation stack,
we can change Karatsuba to accept operands of odd length.
Doing so avoids most of the fixup that the old approach required.
For example, multiplying a pair of 99-word numbers runs
karatsuba on all 99 words now.
This is simpler and about the same speed or, for large cases, faster.

crypto/tls: reject TLS 1.3 compat session ID in TLS 1.2
If we weren't resuming an existing session, and we constructed a TLS 1.3
compatible client hello, ensure the server doesn't echo back the
made up compatibility session ID if we end up handshaking for TLS 1.2.
As part of an effort to make the initial stages of a TLS 1.3 handshake
compatible with TLS 1.2 middleboxes, TLS 1.3 requires that the client
hello contain a non-empty legacy_session_id value. For anti-ossification
purposes it's recommended this ID be randomly generated. This is the
strategy the crypto/tls package takes.
When we follow this approach, but then end up negotiating TLS 1.2, the
server should not have echoed back that random ID to us. It's impossible
for the server to have had a session with a matching ID and so it is
misbehaving and it's prudent for our side to abort the handshake.
See RFC 8446 Section 4.1.2 for more detail:

Adopting this behaviour allows un-ignoring the BoGo

We're already skipping some other GREASE related test as

crypto/tls: ignore TLS 1.3 user canceled alerts
When encountering alertUserCanceled in a TLS 1.3 handshake, ignore the

TLS 1.2 alertLevelWarning alerts are handled.
For broader context, TLS 1.3 removed warning-level alerts except for
alertUserCanceled (RFC 8446, § 6.1). Since at least one major
implementation (https://bugs.openjdk.org/browse/JDK-8323517)
misuses this alert, many TLS stacks now ignore it outright when seen in

With the crypto/tls behaviour changed to match peer implementations we
can now enable the "SendUserCanceledAlerts-TLS13" BoGo test.
"SendUserCanceledAlerts-TooMany-TLS13" remains ignored, because like

crypto/tls: run SkipNewSessionTicket bogo test
This commit removes SkipNewSessionTicket from the bogo_config.json
excluded tests list.
Previously this test was being skipped with a TODO that there might be
a bug here. In practice it seems like there's no bug and the test is
handled correctly by crypto/tls.
When activated, a TLS 1.2 client connecting to the bogo dispatcher goes
through the normal handshake process with the exception that the server
skips sending the NewSessionTicket msg expected by the client in
response to the client's final flight of handshake msgs.
The crypto/tls TLS 1.2 client_handshake.go logic correctly rejects the
unexpected message that follows (ChangeCipherSpec) when trying to read
the bytes necessary to unmarshal the expected NewSessionTicket message
that was omitted.

debug/dwarf: fix problem with DWARF 5 and Seek method
When clients use debug/dwarf to examine DWARF 5 binaries, we can run
into problems when the Seek() method is used to skip ahead from a DIE
in one compilation unit to a DIE in another unit. The problem here is
that it is common for DWARF 5 comp units to have attributes (ex:
DW_AT_addr_base) whose value must be applied as an offset when reading
certain forms (ex: DW_FORM_addrx) within that unit. The existing
implementation didn't have a good way to recover these attrs following
the Seek call, and had to essentially punt in this case, resulting in
incorrect attr values.
This patch adds new support for reading and caching the key comp unit
DIE attributes (DW_AT_addr_base, DW_AT_loclists_base, etc) prior to
visiting any of the DIE entries in a unit, storing the cache values of
these attrs the main table of units. This base attribute
reading/caching behavior also happens (where needed) after Seek calls.
Should resolve delve issue 3861.

internal/godebugs: add decoratemappings as an opaque godebug setting
This adds a new godebug to control whether the runtime applies the
anonymous memory mapping annotations added in https://go.dev/cl/646095.
It is enabled by default.
This has several effects:
* The feature is only enabled by default when the main go.mod has go >=
1.25.
* This feature can be disabled with GODEBUG=decoratemappings=0, or the
equivalents in go.mod or package main. See https://go.dev/doc/godebug.
* As an opaque setting, this option will not appear in runtime/metrics.
* This setting is non-atomic, so it cannot be changed after startup.
I am not 100% sure about my decision for the last two points.
I've made this an opaque setting because it affects every memory mapping
the runtime performs. Thus every mapping would report "non-default
behavior", which doesn't seem useful.
This setting could trivially be atomic and allow changes at run time,
but those changes would only affect future mappings. That seems
confusing and not helpful. On the other hand, going back to annotate or
unannotate every previous mapping when the setting changes is
unwarranted complexity.

crypto/internal/fips140/bigmod: explicitly clear expanded limbs on reset
Russ Cox noticed that reset was clearing limbs up to the *previous* Nat
size, not up to the new size, because clear(x.limbs) was happening
before the x.limbs[:n] reslice.
That's potentially a severe issue, because it may leave garbage in
x.limbs[len(x.limbs):n] if n < cap(x.limbs).
We were saved by an accidental invariant caused by the bug itself,
though: x.limbs[len(x.limbs):cap(x.limbs)] are always zero.
reset was always clearing all exposed (and hence potentially non-zero)
limbs before shrinking the Nat, and the only other function that could
shrink the Nat was trim, which only trims zero limbs.
Near miss.
Preserve the accidental invariant in the fix, because memclr is cheap
and it just proved it can save us from potential mistakes.

Look at the inlining stack of positions for a call site,

go/types,types2: externalize used objects
The 'used' field on Var and PkgName is fundamentally an aspect of the
type checking pass: it records when objects are used, for the purposes
of reporting errors for unused variables or package names. While
expedient and performant, recording this information in the types.Object
instances themselves increases the memory footprint of type-checked
packages, and (as we saw in golang/go#71817) can lead to data races when
Objects are reused in follow-up type checking, such as is done with the
CheckExpr and Eval APIs.
Fix this by externalizing the 'used' information into two maps (one for
variables and one for packages) on the types.Checker, so that they are
garbage-collected after type checking, and cannot be a source of data
races.
Benchmarks showed essentially no change in performance.

cmd/go: skip some tests that run builds in short mode
cmd/go tests that run builds are generally skipped in short mode. This
change will adds skips for some tests that were running builds.
I found these by sorting tests by elapsed time and removing the top
tests that invoked go build. It's our practice to skip tests that run go
build without the -n flag (which prints but doesn't execute commands).
On my work laptop this reduces test run time from about 20 seconds to
about 16 seconds. On my linux workstation it reduces test run time from
about 10 seconds to about 5 seconds.

go/types: add Var.Kind() VarKind method
This CL adds an enum type, VarKind, that discriminates among
the various kinds of Var, and adds setter/getter methods
for Var's kind field.
Beware: NewVar has a weaker postcondition: the Var objects it
returns are not completely initialized and require a call to
Var.SetKind. This should only affect importers.
No changes are needed to the export data, since the kind can
always be deduced from the context when decoding.
See CL 645656 for the corresponding x/tools changes.
