Title:
  Assertion failed: (buf_len != 0), function soread, file socket.c, line
  183.

Status in QEMU:
  Triaged

Bug description:
  I have a virtual raspberry py that I am running qemu 5.1.0 for MacOS.

  Here is the command line I used:

  qemu-system-arm \
    -M versatilepb \
    -cpu arm1176 \
    -m 256 \
    -drive 
file=2020-08-20-raspios-buster-armhf-lite.img,if=none,index=0,media=disk,format=raw,id=disk0
 \
    -device virtio-blk-pci,drive=disk0,disable-modern=on,disable-legacy=off \
    -net nic -net user,hostfwd=tcp::5022-:22 \
    -dtb versatile-pb-buster-5.4.51.dtb \
    -kernel kernel-qemu-5.4.51-buster \
    -append "root=/dev/vda2 panic=1" \
    -no-reboot \
    -serial stdio

  When trying to ssh from another machine while docker was running
  inside the VM, I got the following error:

  Assertion failed: (buf_len != 0), function soread, file 
/private/tmp/qemu-20200813-13289-1g95loa/qemu-5.1.0/slirp/src/socket.c, line 183
  ../boot.sh: line 12:  8592 Abort trap: 6
