Revision f92a80a9972175a6a1d36c6c44be47fb0efd020d authored by Daniele Di Proietto on 28 November 2016, 23:43:53 UTC, committed by David S. Miller on 30 November 2016, 16:00:45 UTC
If nf_ct_frag6_gather() returns an error other than -EINPROGRESS, it means that we still have a reference to the skb. We should free it before returning from handle_fragments, as stated in the comment above.
