[Qemu-devel] [Bug 1796754] Re: ioctl SIOCGIFCONF causes qemu-aarch64-static to crash with "received signal outside vCPU context"

[Ke Liu]

I sent out a patch: 
http://lists.nongnu.org/archive/html/qemu-devel/2018-10/msg01657.html
(Please ignore the other 2 identical patches. It was my first time sending out 
patches and I didn't know it was moderated so I sent it out multiple times).

Title:
  ioctl SIOCGIFCONF causes qemu-aarch64-static to crash with "received
  signal outside vCPU context"

Status in QEMU:
  New

Bug description:
  To reproduce it, compile the attached crash.c under aarch64 to a.out and 
execute on x86_64
  qemu-aarch64-static ./a.out

  It will print the following and crash:

  socket=3
  qemu:handle_cpu_signal received signal outside vCPU context @ pc=0x60038cd6
  qemu:handle_cpu_signal received signal outside vCPU context @ pc=0x6000157a

  The version of qemu-aarch64-static is

  qemu-aarch64 version 3.0.0 (qemu-3.0.0-1.fc29)
  Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers

  But it did also happen in previous versions so it is not a regression
  but a bug existed ever since.
