Subject: linux-user: Return correct errno for unsupported netlink socket
X-Git-Tag: qemu-xen-4.6.0-rc1~380^2~1
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=480eda2eda7c464e252f17ac87ec61bccc14f285;p=qemu-upstream-4.6-testing.git

linux-user: Return correct errno for unsupported netlink socket

This fixes "Cannot open audit interface - aborting." when the
EAFNOSUPPORT errno differs between the target and host
architectures (e.g. mips target and x86_64 host).
