      runtime: save context value in NetBSD sigtramp · 123510bf
      Ian Lance Taylor authored 
      On NetBSD a signal handler returns to the kernel by calling the
setcontext system call with the context passed to the signal handler.
The implementation of runtime·sigreturn_tramp for amd64, copied from the
NetBSD libc, expects that context address to be in r15.  That works in
the NetBSD libc because r15 is preserved across the call to the signal
handler.  It fails in the Go library because r15 is not preserved.
There are various ways to fix this; this one uses the simple approach,
essentially identical to the one in the NetBSD libc, of preserving r15
across the signal handler proper.

Looking at the code for 386 and arm suggests that they are OK.  However,
I have not actually tested them.

Update #14052.

      runtime: on NetBSD and DragonFly drop signal stack in new thread · 4c4476c2
      Ian Lance Taylor authored 
      On NetBSD and DragonFly a newly created thread inherits the signal stack
of the creating thread.  This breaks horribly if both threads get a
signal at the same time.  Fix this by dropping the signal stack in the
newly created thread.  The right signal stack will then get installed
later.

Note that cgo code that calls pthread_create will have the wrong,
duplicated, signal stack in the newly created thread.  I don't see any
way to fix that in Go.  People using cgo to call pthread_create will
have to be aware of the problem.

Fixes #13945.
Fixes #13947.

      net: improve netsh usage in Windows unit tests · 489f65b5
      Tim Ebringer authored 
      The TestInterfaceAddrsWithNetsh Windows unit test parses and compares the
output of the "netsh" command against more low level Windows API calls. In
at least two cases, some quirks of netsh cause these comparisons to fail.

One example appears to be wi-fi adapters. After a reboot, before it has
been allowed to connect to a network, netsh for IPv4 will not show an
address, whereas netsh for IPv6 will. If the interface is allowed to
connect, and then disconnected, netsh for IPv4 now shows an address and
the test will pass.

The fix is to not compare netsh output if the interface is down.

A related issue is that the IPv6 version of "netsh" can return an
IPv4-embedded IPv6 address where the IPv4 component of the address
is in decimal form, whilst the test is expecting hexadecimal form.

For example, output might be:

  Address fe80::5efe:192.168.1.7%6 Parameters
    ...

Whilst this is valid notation, the fix is to recognise this format in the
"netsh" output and re-parse the address into the all-hexadecimal
representation that the test is expecting.

Fixes #13981

      crypto/tls: note in comment that Certificate.Leaf is nil after parsing. · b203f88c
      Adam Langley authored 
      LoadX509KeyPair and X509KeyPair don't retain the parsed form of
certificates in their return value because it's generally not needed.
This change makes that clear in the comment.
