      testing: callerName only needs one PC in the traceback · 1ab063ce
      Keith Randall authored 
      callerName requested 2 PCs from Callers, and that causes
both to be looked up in the file/line mapping.
We really only need to do the work for one PC.
(And in fact the caller doesn't need file/line at all, but
the Callers API can't express that.)

We used to request 2 PCs because in 1.11 and earlier we
stored an inline skip count in the second entry.
That's not necessary any more (as of 1.12).

Fixes #32093

      crypto/tls: fix TestVerifyHostnameResumed · e22e2b37
      Filippo Valsorda authored 
      In TLS 1.3 session tickets are delivered after the handshake, and it
looks like now the Google servers wait until the first flight of data to
send them (or our timeout is too low). Cause some data to be sent so we
can avoid the guessing game.

      net/http/httputil: remove os.Stderr claim in ReverseProxy.ErrorLog docs · 3f7c5608
      Dmitri Shuralyov authored 
      The motivation for doing so is to avoid making inaccurate claims.
Logging may not go to os.Stderr if anyone overrides the log package's
default output via https://godoc.org/log#SetOutput. Saying that
the standard logger is used should be sufficient to explain the
behavior, and users can infer that os.Stderr is used by default,
unless it's changed.

This change is the same as what was applied to http.Server.ErrorLog
documentation in CL 53950.

      cmd/go: don't attempt to downgrade to incompatible versions · 06642d8e
      Jay Conrod authored 
      When we downgrade a module (using 'go get m@none' or similar), we
exclude versions of other modules that depend on it. We'll try
previous versions (in the "versions" list returned by the proxy or in
codeRepo.Versions for vcs) until we find a version that doesn't
require an excluded module version.

If older versions of a module are broken for some reason,
mvs.Downgrade currently panics. With this change, we ignore versions
with errors during downgrade.

A frequent cause of this is incompatible v2+ versions. These are
common if a repository tagged v2.0.0 before migrating to modules, then
tagged v2.0.1 with a go.mod file later. v2.0.0 is incorrectly
considered part of the v2 module.

      errors: update As example to include else case · 703fb665
      Jean de Klerk authored 
      The current example illustrates using As when the error is able to be
interpreted as an os.PathError, but elides the "else" case. This CL adds the
small extra else case to make it clear that it's not safe to assume As will
return true.

This CL also squash the err instantiation and the err nil check into one line
for brevity.

      crypto/tls: add support for Ed25519 certificates in TLS 1.2 and 1.3 · f3533858
      Filippo Valsorda authored 
      Support for Ed25519 certificates was added in CL 175478, this wires them
up into the TLS stack according to RFC 8422 (TLS 1.2) and RFC 8446 (TLS 1.3).

RFC 8422 also specifies support for TLS 1.0 and 1.1, and I initially
implemented that, but even OpenSSL doesn't take the complexity, so I
just dropped it. It would have required keeping a buffer of the
handshake transcript in order to do the direct Ed25519 signatures. We
effectively need to support TLS 1.2 because it shares ClientHello
signature algorithms with TLS 1.3.

While at it, reordered the advertised signature algorithms in the rough
order we would want to use them, also based on what curves have fast
constant-time implementations.

Client and client auth tests changed because of the change in advertised
signature algorithms in ClientHello and CertificateRequest.

Fixes #25355
