The function tipc_msg_extract() is using skb_clone() to clone inner messages from a message bundle buffer. Although this method is safe, it has an undesired effect that each buffer clone inherits the true-size of the bundling buffer. As a result, the buffer clone almost always ends up with being copied anyway by the message validation function. This makes the cloning into a sub-optimization. In this commit we take the consequence of this realization, and copy each inner message to a separately allocated buffer up front in the extraction function. As a bonus we can now eliminate the two cases where we had to copy re-routed packets that may potentially go out on the wire again.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
