The /proc interface for nf_conntrack displays the "error" counter as "icmp_error". It makes sense to not increment "invalid" when failing to handle an icmp packet since those are special. For example, its possible for conntrack to see partial and/or fragmented packets inside icmp errors. This should be a separate event and not get mixed with the "invalid" counter. Likewise, remove the "error" increment for errors from get_l4proto(). After this, the error counter will only increment for errors coming from icmp(v6) packet handling.

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.
