Subject: [IPSEC]: Fix inetpeer leak in ipv4 xfrm dst entries.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=26db167702756d0022f8ea5f1f30cad3018cfe31;p=linux-beck.git

[IPSEC]: Fix inetpeer leak in ipv4 xfrm dst entries.

We grab a reference to the route's inetpeer entry but
forget to release it in xfrm4_dst_destroy().
