[ Upstream commit 7384b538d3aed2ed49d3575483d17aeee790fb06 ]
When we free skb at tipc_data_input, we return a 'false' boolean. Then, skb passed to subcalling tipc_link_input in tipc_link_rcv,
<snip> 1303 int tipc_link_rcv: ... 1354 if (!tipc_data_input(l, skb, l->inputq)) 1355 rc |= tipc_link_input(l, skb, l->inputq); </snip>
Fix it by simple changing to a 'true' boolean when skb is being free-ed. Then, tipc_link_rcv will bypassed to subcalling tipc_link_input as above condition.
