Looks like if a bpf program gets inserted and then removed, hdev->bpf.device_data is then allocated, but the loop iterating over the bpf program is never assigning ret. This is a problem and also revealed another bug in which only the last value of ret was checked. This effectively meant than only the last program in the chain could change the size of the incoming buffer.

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 reStructuredText 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.
