Subject: [PATCH V2 0/3] handle polling errors in vhost/vhost_net
Date: Sat, 5 Jan 2013 17:34:03 +0800 [thread overview]
Message-ID: <1357378446-19656-1-git-send-email-jasowang@redhat.com> (raw)
This is an update version of last version to fix the handling of polling errors
in vhost/vhost_net.
Currently, vhost and vhost_net ignores errors of polling which can lead kernel
crashing for buggy/malicious userspace. Fix this by extending the idea of tx
polling state to all other vhost_polls and changing the state only when polling
succeed.

vhost_net: correct error handling in vhost_net_set_backend()
vhost: handle polling errors
tuntap: don't add to waitqueue when POLLERR
