Kan Li's patch was applied to master as commit 22e4a267a6627e5b5b, so this will be fixed in the upcoming QEMU 4.0 release. ** Changed in: qemu Status: In Progress => Fix Committed -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1796754 Title: ioctl SIOCGIFCONF causes qemu-aarch64-static to crash with "received signal outside vCPU context" Status in QEMU: Fix Committed 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.

I was hit by this issue when I tried to run some Java program. And it turns out jdk sets the buf to NULL: http://hg.openjdk.java.net/jdk7/jdk7/jdk/file/887e525597f8/src/solaris/native/java/net/NetworkInterface.c#l1042 Setting to NULL is valid according to http://man7.org/linux/man- pages/man7/netdevice.7.html But qemu doesn’t handle the case: https://github.com/qemu/qemu/blob/aa8e26de9617756febcbf794dda965df307fdaaa /linux-user/syscall.c#L4105 I guess qemu developers didn’t handle the case because the Linux kernel changed and they were based on behavior of old version: https://linux.die.net/man/7/netdevice Please add the support for it otherwise a wide range of network related Java programs won’t run. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1796754 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.
