9f39a43e0d crypto/tls: de-prioritize AES-GCM ciphers when lacking hardware support
When either the server or client are lacking hardware support for
AES-GCM ciphers, indicated by the server lacking the relevant
instructions and by the client not putting AES-GCM ciphers at the top
of its preference list, reorder the preference list to de-prioritize
AES-GCM based ciphers when they are adjacent to other AEAD ciphers.

Also updates a number of recorded openssl TLS tests which previously
only specified TLS 1.2 cipher preferences (using -cipher), but not
TLS 1.3 cipher preferences (using -ciphersuites), to specify both
preferences, making these tests more predictable.

Fixes #41181.

d7fff1f2cf crypto/tls: ensure the server picked an advertised ALPN protocol
This is a SHALL in RFC 7301, Section 3.2.

Also some more cleanup after NPN, which worked the other way around

fdecb5c5b4 crypto/tls: add HandshakeContext method to Conn
Adds the (*tls.Conn).HandshakeContext method. This allows
us to pass the context provided down the call stack to
eventually reach the tls.ClientHelloInfo and
tls.CertificateRequestInfo structs.
These contexts are exposed to the user as read-only via Context()
methods.

This allows users of (*tls.Config).GetCertificate and
(*tls.Config).GetClientCertificate to use the context for
request scoped parameters and cancellation.

Replace uses of (*tls.Conn).Handshake with (*tls.Conn).HandshakeContext
where appropriate, to propagate existing contexts.

Fixes #32406

06538fa723 cmd/go/internal/modget: resolve paths at the requested versions
Previously, we resolved each argument to 'go get' to a package path or
module path based on what was in the build list at existing versions,
even if the argument specified a different version explicitly. That
resulted in bugs like #37438, in which we variously resolved the wrong
version or guessed the wrong argument type for what is unambiguously a
package argument at the requested version.

We were also using a two-step upgrade/downgrade algorithm, which could
not only upgrade more that is strictly necessary, but could also
unintentionally upgrade *above* the requested versions during the
downgrade step.

This change instead uses an iterative approach, with an explicit
disambiguation step for the (rare) cases where an argument could match
the same package path in multiple modules. We use a hook in the
package loader to halt package loading as soon as an incorrect version
is found — preventing over-resolving — and verify that the result
after applying downgrades successfully obtained the requested versions
of all modules.

Making 'go get' be correct and usable is especially important now that
we are defaulting to read-only mode (#40728), for which we are
recommending 'go get' more heavily.

While I'm in here refactoring, I'm also reworking the API boundary
between the modget and modload packages. Previously, the modget
package edited the build list directly, and the modload package
accepted the edited build list without validation. For lazy loading
(#36460), the modload package will need to maintain additional
metadata about the requirement graph, so it needs tighter control over
the changes to the build list.

As of this change, modget no longer invokes MVS directly, but instead
goes through the modload package. The resulting API gives clearer
reasons in case of updates, which we can use to emit more useful
errors.

Updates #40728

2b9b2720b8 spec: split shift examples into groups for 32- and 64-bit ints
In the current (pre-CL) version of the spec, the 2nd last shift
example appears to be using the array declared in the last example.
On a 32-bit platform, that array would have length 0, which would
lead to a panic in the 2nd last example. Also, if this code were
inside a function, it wouldn't compile (array declared after use).

Use an explicitly declared array for that specific shift example.
Also, split out all cases that produce different results for 32-
vs 64-bit ints.

Fixes #41835.

de74ea5d74 cmd/go: set TOOLEXEC_IMPORTPATH for -toolexec tools
This way, a -toolexec tool can tell precisely what package is being
built when it's run. This was very hard to do before, because the tool
had to piece together that information given the build action's
arguments or flags.

Since there wasn't a good set of tests for -toolexec, add one in the
form of a test script. It builds a simple set of packages with a variety
of build tools, to ensure that all the cases behave as expected.

Like other recent master changes, include the changelog item for this
user-facing change too.

Fixes #15677.

7c58ef732e runtime: implement GODEBUG=inittrace=1 support
Setting inittrace=1 causes the runtime to emit a single line to standard error for
each package with init work, summarizing the execution time and memory allocation.

The emitted debug information for init functions can be used to find bottlenecks
or regressions in Go startup performance.

Packages with no init function work (user defined or compiler generated) are omitted.

Tracing plugin inits is not supported as they can execute concurrently. This would
make the implementation of tracing more complex while adding support for a very rare
use case. Plugin inits can be traced separately by testing a main package importing
the plugins package imports explicitly.

8f26b57f9a cmd/compile: split exported/non-exported methods for interface type
Currently, mhdr/methods is emitted with the same len/cap. There's no way
to distinguish between exported and non-exported methods statically.

This CL splits mhdr/methods into two parts, use "len" for number of
exported methods, and "cap" for all methods. This fixes the bug in
issue #22075, which intends to return the number of exported methods but
currently return all methods.

Note that with this encoding, we still can access either
all/exported-only/non-exported-only methods:

	mhdr[:cap(mhdr)]          // all methods
	mhdr                      // exported methods
	mhdr[len(mhdr):cap(mhdr)] // non-exported methods

Thank to Matthew Dempsky (@mdempsky) for suggesting this encoding.

Fixes #22075

The current specification does not foresee a SameSite attribute without

way that would likely be ignored by well-impelemented clients, it is
better to not rely on this kind of quirks.

Extends the IA5String encoding restrictions that are currently applied
to name constraints to dNSName, rfc822Name, and
uniformResourceIdentifier elements of the SAN. The utility function
isIA5String is updated to use unicode.MaxASCII rather than utf8.RuneSelf
as it is somewhat more readable.

Certificates that include these badly encoded names do exist, but are
exceedingly rare. zlint and other linters enforce this encoding and
searching censys.io reveals only three currently trusted certificates
with this particular encoding issue.

a413908dd0 all: add GOOS=ios
Introduce GOOS=ios for iOS systems. GOOS=ios matches "darwin"
build tag, like GOOS=android matches "linux" and GOOS=illumos
matches "solaris". Only ios/arm64 is supported (ios/amd64 is
not).

GOOS=ios and GOOS=darwin remain essentially the same at this
point. They will diverge at later time, to differentiate macOS
and iOS.

Uses of GOOS=="darwin" are changed to (GOOS=="darwin" || GOOS=="ios"),
except if it clearly means macOS (e.g. GOOS=="darwin" && GOARCH=="amd64"),
it remains GOOS=="darwin".

that suffix-length MUST be of the form 1*DIGIT aka a non-negative digit.

bb54a855a9 net/http: handle Request.URL.RawPath in StripPrefix
The StripPrefix wrapper strips a prefix string from the request's
URL.Path field, but doesn't touch the RawPath field. This leads to the
confusing situation when StripPrefix handles a request with URL.RawPath
populated (due to some escaped characters in the request path) and the
wrapped request's RawPath contains the prefix but Path does not.

This change modifies StripPrefix to strip the prefix from both Path and
RawPath. If there are escaped characters in the prefix part of the
request URL the stripped handler serves a 404 instead of invoking the
underlying handler with a mismatched Path/RawPath pair.

This is a backward incompatible change for a very small minority of
requests; I would be surprised if anyone is depending on this behavior,
but it is possible. If that's the case, we could make a more
conservative change where the RawPath is trimmed if possible, but when
the prefix contains escaped characters then we don't 404 but rather send
through the invalid Path/RawPath pair as before.

Fixes #24366

In Go 1.15 we switched the default linking mode for PIE on
Linux/AMD64 and Linux/ARM64 to internal linking. Clarify that
the previous behavior (external linking) can still be used with
a flag.

Fixes #40719.

6f264801a7 go/printer: remove exported StdFormat flag
The StdFormat flag was added as part of CL 231461, where the primary aim
was to fix the bug #37476. It's expected that the existing printer modes
only adjust spacing but do not change any of the code text itself. A new
printing flag served as a way for cmd/gofmt and go/format to delegate
a part of formatting work to the printer—where it's more more convenient
and efficient to perform—while maintaining current low-level printing
behavior of go/printer unmodified.

We already have cmd/gofmt and the go/format API that implement standard
formatting of Go source code, so there isn't a need to expose StdFormat
flag to the world, as it can only cause confusion.

Consider that to format source in canonical gofmt style completely it
may require tasks A, B, C to be done. In one version of Go, the printer
may do both A and B, while cmd/gofmt and go/format will do the remaining
task C. In another version, the printer may take on doing just A, while
cmd/gofmt and go/format will perform B and C. This makes it hard to add
a gofmt-like mode to the printer without compromising on above fluidity.

This change prefers to shift back some complexity to the implementation
of the standard library, allowing us to avoid creating the new exported
printing flag just for the internal needs of gofmt and go/format today.

We may still want to re-think the API and consider if something better
should be added, but unfortunately there isn't time for Go 1.15. We are
not adding new APIs now, so we can defer this decision until Go 1.16 or
later, when there is more time.

For #37476.
For #37453.
For #39489.
For #37419.

7b872b6d95 crypto/tls: restore OCSP and SCTs during session resumption
Restore previously sent SCTs and stapled OCSP response during session
resumption for both TLS 1.2 and 1.3. This behavior is somewhat
complicated for TLS 1.2 as SCTs are sent during the server hello,
so they override what is saved in ClientSessionState. It is likely
that if the server is sending a different set of SCTs there is probably
a reason for doing so, such as a log being retired, or SCT validation
requirements changing, so it makes sense to defer to the server in
that case.

Fixes #39075

2cd2ff6f56 all: avoid awkward wording from CL 236857
CL 236857 removed all uses of whitelist/blacklist, which is great.
But it substituted awkward phrasing using allowlist/blocklist,
especially as verbs or participles. This CL uses more standard English,
like "allow the function" or "blocked functions" instead of
"allowlist the function" or "blocklisted functions".

608cdcaede all: replace usages of whitelist/blacklist and master/slave
There's been plenty of discussion on the usage of these terms in tech.
I'm not trying to have yet another debate. It's clear that there are
people who are hurt by them and who are made to feel unwelcome by their
use due not to technical reasons but to their historical and social
context. That's simply enough reason to replace them.

Anyway, allowlist and blocklist are more self-explanatory than whitelist
and blacklist, so this change has negative cost.

Didn't change vendored, bundled, and minified files. Nearly all changes
are tests or comments, with a couple renames in cmd/link and cmd/oldlink
which are extremely safe. This should be fine to land during the freeze
without even asking for an exception.

Ctty was always handled as a child descriptor, but in some cases
passing a parent descriptor would also work. This depended on
unpredictable details of the implementation. Reject those cases to
avoid confusion.

Also reject setting both Setctty and Foreground, as they use Ctty
in incompatible ways. It's unlikely that any programs set both fields,
as they don't make sense together.

d422f54619 os, net: define and use os.ErrDeadlineExceeded
If an I/O operation fails because a deadline was exceeded,
return os.ErrDeadlineExceeded. We used to return poll.ErrTimeout,
an internal error, and told users to check the Timeout method.
However, there are other errors with a Timeout method that returns true,
notably syscall.ETIMEDOUT which is returned for a keep-alive timeout.
Checking errors.Is(err, os.ErrDeadlineExceeded) should permit code
to reliably tell why it failed.

This change does not affect the handling of net.Dialer.Deadline,
nor does it change the handling of net.DialContext when the context
deadline is exceeded. Those cases continue to return an error
reported as "i/o timeout" for which Timeout is true, but that error
is not os.ErrDeadlineExceeded.

Fixes #31449

f049d911e9 cmd/compile: be stricter about recognizing safety rule #4
unsafe.Pointer safety rule #4 says "The compiler handles a Pointer
converted to a uintptr in the argument list of a call". Within escape
analysis, we've always required this be a single conversion
unsafe.Pointer->uintptr conversion, but the corresponding logic in
order is somewhat laxer, allowing arbitrary chains of OCONVNOPs from
unsafe.Pointer to uintptr.

This CL changes order to be stricter to match escape analysis.

Passes toolstash-check.

e5bd6e1c79 runtime: crash on SI_USER SigPanic signal
Clean up the code a little bit to make it clearer:

Don't check throwsplit for a SI_USER signal.

If throwsplit is set for a SigPanic signal, always throw;
discard any other flags.

0eb694e9c2 reflect: disallow invoking methods on unexported embedded fields
Given:

    type u struct{}
    func (u) M() {}

    type t struct { u; u2 u }

    var v = reflect.ValueOf(t{})

Package reflect allows:

    v.Method(0)          // v.M
    v.Field(0).Method(0) // v.u.M

but panics from:

    v.Field(1).Method(0) // v.u2.M

because u2 is not an exported field. However, u is not an exported
field either, so this is inconsistent.

It seems like this behavior originates from #12367, where it was
decided to allow traversing unexported embedded fields to be able to
access their exported fields, since package reflect doesn't provide an
alternative way to access promoted fields directly.

But extending that logic to promoted *methods* was inappropriate,
because package reflect's normal method handling logic already handles
promoted methods correctly. This CL corrects that mistake.

Fixes #38521.
