            Bug ID: 98610
           Summary: syscall.TestUnshareUidGidMapping sporadically fails on
                    powerpc64le
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
          Assignee: ian at airs dot com
          Reporter: murphyp at linux dot vnet.ibm.com
                CC: cmang at google dot com
  Target Milestone: ---

openat is not always called through the libc variadic wrapper in libgo.  This
results in stack corruption on powerpc64le.

    syscall: ensure openat uses variadic libc wrapper

    On powerpc64le, this caused a failure in TestUnshareUidGidMapping
    due to stack corruption which resulted in a bogus execve syscall.

    Use the existing c wrapper to ensure we respect the ppc abi for
    variadic functions.

    Fixes PR go/98610
