[Qemu-devel] [Bug 1821006] Re: qemu: Unsupported syscall: 382

[Peter Maydell]

...that said, we should implement renameat2 provided that the host
kernel does. What host kernel version are you using, and what host
kernel minimum requirement was the glibc for your guest compiled to
require? renameat2 was added in kernel 3.15, so if your host kernel is
older than this but your guest glibc assumes it has at least 3.15 then
there's no way QEMU can bridge this gap.

Title:
  qemu: Unsupported syscall: 382

Status in QEMU:
  New

Bug description:
  I used

  qemu-user-static/stable,stable,now 1:2.8+dfsg-6+deb9u5 amd64
  [installed]

  When I try to build an image of a docker for an arm, an error occurs.

  This affects the operation of applications.

  
  Dockerfile

  ARG ARCH
  FROM ${ARCH}/debian:buster-slim

  RUN \
      printf "Install dependencies...\n" && \
      apt-get update && \
      apt-get install -y --no-install-recommends ca-certificates curl

  RUN curl https://google.com

  EOF

  The command that I run

  docker build --build-arg ARCH=arm32v7 --file ./Dockerfile -t test .

  
  address@hidden:/lib/binfmt.d# cat qemu-arm-static.conf 
  
:qemu-arm:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\x00\x00\x00\x00\x00\x00\x00\x00\xfe\xff\xff\xff:/usr/bin/qemu-arm-static:F
