39d4bb9c0f [release-branch.go1.9] cmd/go: correct directory used in checkNestedVCS test
This error was not used when using git because nested git is permitted.
Add test using Mercurial, so that at least we have a test, even though
the test is not run by default.

Fixes #22157
Fixes #22201

bfc22319aa [release-branch.go1.9] crypto/x509: reject intermediates with unknown critical extensions.
In https://golang.org/cl/9390 I messed up and put the critical extension
test in the wrong function. Thus it only triggered for leaf certificates
and not for intermediates or roots.

In practice, this is not expected to have a security impact in the web
PKI.

ebfcdef901 [release-branch.go1.9] runtime: make runtime.GC() trigger GC even if GOGC=off
Currently, the priority of checks in (gcTrigger).test() puts the
gcpercent<0 test above gcTriggerCycle, which is used for runtime.GC().
This is an unintentional change from 1.8 and before, where
runtime.GC() triggered a GC even if GOGC=off.

Fix this by rearranging the priority so the gcTriggerCycle test
executes even if gcpercent < 0.

Fixes #22023.

but not for the zero case.

This also removes some of the special MOVDstorezero cases since
they can be handled by the general LowerZero case.

include cases where the target is not aligned to at least 4.

c6388d381e [release-branch.go1.9] runtime: capture runtimeInitTime after nanotime is initialized
CL 36428 changed the way nanotime works so on Darwin and Windows it
now depends on runtime.startNano, which is computed at runtime.init
time. Unfortunately, the `runtimeInitTime = nanotime()` initialization
happened *before* runtime.init, so on these platforms runtimeInitTime
is set incorrectly. The one (and only) consequence of this is that the
start time printed in gctrace lines is bogus:

gc 1 18446653480.186s 0%: 0.092+0.47+0.038 ms clock, 0.37+0.15/0.81/1.8+0.15 ms cpu, 4->4->1 MB, 5 MB goal, 8 P

To fix this, this commit moves the runtimeInitTime initialization to
shortly after runtime.init, at which point nanotime is safe to use.

This also requires changing the condition in newproc1 that currently
uses runtimeInitTime != 0 simply to detect whether or not the main M
has started. Since runtimeInitTime could genuinely be 0 now, this
introduces a separate flag to newproc1.

Fixes #21554.

1900d34a10 [release-branch.go1.9] net/smtp: fix PlainAuth to refuse to send passwords to non-TLS servers
PlainAuth originally refused to send passwords to non-TLS servers
and was documented as such.

In 2013, issue #5184 was filed objecting to the TLS requirement,
despite the fact that it is spelled out clearly in RFC 4954.
The only possibly legitimate use case raised was using PLAIN auth
for connections to localhost, and the suggested fix was to let the
server decide: if it advertises that PLAIN auth is OK, believe it.
That approach was adopted in CL 8279043 and released in Go 1.1.

Unfortunately, this is exactly wrong. The whole point of the TLS
requirement is to make sure not to send the password to the wrong
server or to a man-in-the-middle. Instead of implementing this rule,
CL 8279043 blindly trusts the server, so that if a man-in-the-middle
says "it's OK, you can send me your password," PlainAuth does.
And the documentation was not updated to reflect any of this.

This CL restores the original TLS check, as required by RFC 4954
and as promised in the documentation for PlainAuth.
It then carves out a documented exception for connections made
to localhost (defined as "localhost", "127.0.0.1", or "::1").

Cherry-pick of CL 68170.

9a4e7942ea [release-branch.go1.9] cmd/compile: remove gc.Sysfunc calls from 387 backend
[This is a cherry-pick of CL 54090 to the 1.9 release branch.]

gc.Sysfunc must not be called concurrently.
We set up runtime routines used by the backend
prior to doing any backend compilation.
I missed the 387 ones; fix that.

Sysfunc should have been unexported during 1.9.
I will rectify that in a subsequent CL.

Fixes #21352

42046e8989 [release-branch.go1.9] runtime: fix false positive race in profile label reading
Because profile labels are copied from the goroutine into the tag
buffer by the signal handler, there's a carefully-crafted set of race
detector annotations to create the necessary happens-before edges
between setting a goroutine's profile label and retrieving it from the
profile tag buffer.

Given the constraints of the signal handler, we have to approximate
the true synchronization behavior. Currently, that approximation is
too weak.

Ideally, runtime_setProfLabel would perform a store-release on
&getg().labels and copying each label into the profile would perform a
load-acquire on &getg().labels. This would create the necessary
happens-before edges through each individual g.labels object.

Since we can't do this in the signal handler, we instead synchronize
on a "labelSync" global. The problem occurs with the following
sequence:

1. Goroutine 1 calls setProfLabel, which does a store-release on
   labelSync.

2. Goroutine 2 calls setProfLabel, which does a store-release on
   labelSync.

3. Goroutine 3 reads the profile, which does a load-acquire on
   labelSync.

The problem is that the load-acquire only synchronizes with the *most
recent* store-release to labelSync, and the two store-releases don't
synchronize with each other. So, once goroutine 3 touches the label
set by goroutine 1, we report a race.

The solution is to use racereleasemerge. This is like a
read-modify-write, rather than just a store-release. Each RMW of
labelSync in runtime_setProfLabel synchronizes with the previous RMW
of labelSync, and this ultimately carries forward to the load-acquire,
so it synchronizes with *all* setProfLabel operations, not just the
most recent.

The code was adding race.Errors to t.raceErrors before checking

to change Failed, since that would affect tests themselves, so modify
the harness to not unnecessarily change t.raceErrors.

5927854f7d [release-branch.go1.9] cmd/compile: add rules handling unsigned div/mod by constant 1<<63
Cherry-pick CL 56890.

Normally 64-bit div/mod is turned into runtime calls on 32-bit
arch, but the front end leaves power-of-two constant division
and hopes the SSA backend turns into a shift or AND. The SSA rule is

(Mod64u <t> n (Const64 [c])) && isPowerOfTwo(c) -> (And64 n (Const64 <t> [c-1]))

But isPowerOfTwo returns true only for positive int64, which leaves
out 1<<63 unhandled. Add a special case for 1<<63.

Fixes #21517.
