    • syscall: fix creds_test to reliably close os.File · 85c2f96c
      Uncovered by Uros Bizjak.
      
      Before this patch the test would close the file descriptor but
      not the os.File.  When the os.File was GC'ed, the finalizer
      would close the file descriptor again.  That would cause
      problems if the same file descriptor were returned by a later
      call to open in another test.
      
      On my system:
      
      > GOGC=30 go test
      --- FAIL: TestPassFD (0.04 seconds)
      passfd_test.go:62: 	FileConn: dup: bad file descriptor

    • Avoid conservative behavior in REE by allowing removal of redundant extends when... · ca3f371f
      Avoid conservative behavior in REE by allowing removal of redundant extends
      when the def feeds another extend with a different mode. This works because
      in merge_def_and_ext only calls combine_set_extension if the candidate for
      removal has a wider mode than the def extend's mode, otherwise the def extend
      mode is preserved. In combine_set_extension the def is modified to use the
      wider candidate's mode.
