For mips, this has been fixed by upstream commit 2e6eeb67429a7e0683d3d1a75ca497dd67c751e4 which I have attached. It's present in the master branch, but not in any stable branches (note I am not that familiar with upstream qemu development). glibc in stretch uses the sendmmsg syscall when doing DNS lookups which was not wired up correctly in qemu. Thanks, James

Subject: [PATCH] linux-user: Update mips_syscall_args[] array in main.c
Array mips_syscall_args[] determines number of arguments for each
syscall on Mips32. It wasn't updated with newer syscalls. Also,
preadv and pwritev have 5 arguments, not 6.
