      runtime, syscall: workaround for bug in Linux's execve · 91139b87
      John R. Lenton authored 
      Linux's execve has (at the time of writing, and since v2.6.30) a bug when it ran
concurrently with clone, in that it would fail to set up some datastructures if
the thread count before and after some steps differed. This is described better
and in more detail by Colin King in Launchpad¹ and kernel² bugs. When a program
written in Go runtime.Exec's a setuid binary, this issue may cause the resulting
process to not have the expected uid. This patch works around the issue by using
a mutex to serialize exec and clone.

      syscall: mark forkAndExecInChild1 noinline · 87adaf4c
      Austin Clements authored 
      This certainly won't get inlined right now, but in the spirit of
making this more robust, we have to disable inlining because inlining
would defeat the purpose of separating forkAndExecInChild1 into a
separate function.

Updates #20732.

      syscall: use CLONE_VFORK safely · 67e53754
      Austin Clements authored 
      Currently, CLONE_VFORK is used without much regard to the stack. This
is dangerous, because anything the child does to the stack is visible
to the parent. For example, if the compiler were to reuse named stack
slots (which it currently doesn't do), it would be easy for the child
running in the same stack frame as the parent to corrupt local
variables that the parent then depended on. We're not sure of anything
specific going wrong in this code right now, but it is at best a
ticking time bomb.

CLONE_VFORK can only safely be used if we ensure the child does not
execute in any of the active stack frames of the parent. This commit
implements this by arranging for the parent to return immediately from
the frame the child will operate in, and for the child to never return
to the frame the parent will operate in.

Fixes #20732.

      testing: harmonize handling of prefix-matched benchmarks · a2a3ace5
      Russ Cox authored 
      If you have BenchmarkX1 with sub-benchmark Y
and you have BenchmarkX2 with no sub-benchmarks,
then

	go test -bench=X/Y

runs BenchmarkX1 once with b.N=1 (to find out about Y)
and then not again, because it has sub-benchmarks,
but arguably also because we're interested in Y.

In contrast, it runs BenchmarkX2 in full, even though clearly
that is not relevant to the match X/Y. We do have to run X2
once with b.N=1 to probe for having X2/Y, but we should not
run it with larger b.N.

Fixes #20589.

      encoding: fix endless loop in TestDecoderBuffering · 3e0c21e0
      Mark Ryan authored 
      The ascii85, base32 and base64 packages all contain a test called
TestDecoderBuffering.  Each of these tests contain a loop that ignores
the error returned from the Read method of their decoders.  The result
being that the tests loop for ever if the decoders actually return an
error.  This commit fixes the issue by terminating the loops if an error
occurs and failing the tests with a suitable error message.

      image/gif: fix writeImageBlock with SubImages · c52aca1c
      Jed Denlea authored 
      If an image has been cropped horizontally, writeImageBlock detects that
its width and Stride differ and acts accordingly.

However, if an image has been cropped vertically, trimming from the
bottom, the whole original image will be written in place.  This results
in more data in the LZW stream than necessary, and many decoders
including image/gif's itself will fail to load.

Fixes #20692
