For now, No matter what error pointer ip_neigh_for_gw() returns, ip_finish_output2() always return -EINVAL, which may mislead the upper users. For exemple, an application uses sendto to send an UDP packet, but when the neighbor table overflows, sendto() will get a value of -EINVAL, and it will cause users to waste a lot of time checking parameters for errors. Return the real errno instead of -EINVAL.

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.
