Subject: [IPV6]: /proc/net/anycast6 unbalanced inet6_dev refcnt
X-Git-Tag: v2.6.16.44-rc1~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=42e1e229bad37376acf033f14baad9fca2e8584f;p=thirdparty%2Fkernel%2Fstable.git

[IPV6]: /proc/net/anycast6 unbalanced inet6_dev refcnt

Reading /proc/net/anycast6 when there is no anycast address
on an interface results in an ever-increasing inet6_dev reference
count, as well as a reference to the netdevice you can't get rid of.
