[ 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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
