Subject: [Qemu-devel] [PATCH] seccomp: add arch_prctl() to the syscall whitelist
Date: Thu, 18 Jul 2013 09:57:03 -0400 [thread overview]
Message-ID: <20130718135703.8247.19213.stgit@localhost> (raw)
It appears that even a very simple /etc/qemu-ifup configuration can
require the arch_prctl() syscall, see the example below:
#!/bin/sh
/sbin/ifconfig $1 0.0.0.0 up
/usr/sbin/brctl addif <switch> $1
