Subject: [PATCH] IPV6: /proc/net/anycast6 unbalanced inet6_dev refcnt
X-Git-Tag: v2.6.20.17~12
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ac82581f098be0d3f6ef011d2b168181f4f79a0e;p=thirdparty%2Fkernel%2Fstable.git

[PATCH] 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.
