3.6.11.1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Romain KUNTZ [ Upstream commit 2894f6da7e382a42948cc42ab52148dddf281c48 ] Neighbor is cloned in xfrm6_fill_dst but seems to never be released. Neighbor entry should be released when XFRM6 dst entry is destroyed in xfrm6_dst_destroy, otherwise references may be kept forever on the device pointed by the neighbor entry. I may not have understood all the subtleties of XFRM & dst so I would be happy to receive comments on this patch. Signed-off-by: Romain Kuntz Signed-off-by: David S.
