Subject: [PATCH libnetfilter_queue 1/2] src: pktb_trim() was not updating tail after updating len
Date: Mon, 11 Nov 2019 15:17:22 +1100	[thread overview]
Message-ID: <20191111041723.30660-2-duncan_roe@optusnet.com.au> (raw)
In-Reply-To: <20191111041723.30660-1-duncan_roe@optusnet.com.au>

skb->tail is used in many places, so it's important to keep it up to date.

Updated:
