The size of struct th_header is 8 byte and the size of struct th_sweep is 16 byte. The memory for is allocated, initialized, used and deallocated a few lines later. It is more efficient to avoid the allocation/free dance and assign the values directly to skb's data part instead of using memcpy() for it. Avoid an allocation of struct th_sweep/th_header and use the resulting skb pointer instead.

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.
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.
