[Qemu-devel] [Bug 636095] [NEW] tap downscript is not executed when exiting qemu through "quit" monitor command

[Max]

Public bug reported:

When you tell qemu to shutdown using the "quit" monitor command, the
downscript of the tap interface is not executed.


To reproduce:


Create the test script /tmp/qemu-ifdown-test.sh :

==
#!/bin/bash

touch /tmp/is_this_working
==

Run:

==
# chmod +x /tmp/qemu-ifdown-test.sh
# qemu-system-x86_64 -daemonize -net nic -net 
tap,script=/etc/qemu-ifup,downscript=/tmp/qemu-ifdown-test.sh -monitor 
unix:/tmp/monitor.socket,nowait,server
VNC server running on `127.0.0.1:5900'
# nc -U /tmp/monitor.socket 
QEMU 0.12.5 monitor - type 'help' for more information
(qemu) quit
quit
# ls /tmp/is*
ls: cannot access /tmp/is*: No such file or directory

==

If I quit qemu by sending a SIGTERM instead of using the "quit" command,
the downscript does get executed:

==
# qemu-system-x86_64 -daemonize -net nic -net 
tap,script=/etc/qemu-ifup,downscript=/tmp/qemu-ifdown-test.sh -monitor 
unix:/tmp/monitor.socket,nowait,server
VNC server running on `127.0.0.1:5900'
# killall qemu-system-x86_64
# ls /tmp/is*
/tmp/is_this_working
==

Issue occurs with both 0.12.3 and 0.12.5
