[ Upstream commitd13f048dd4] Modify the header size check in geneve6_xmit_skb and geneve_xmit_skb to use pskb_inet_may_pull rather than pskb_network_may_pull. This fixes two kernel selftest failures introduced by the commit introducing the checks: IPv4 over geneve6: PMTU exceptions IPv4 over geneve6: PMTU exceptions - nexthop objects It does this by correctly accounting for the fact that IPv4 packets may transit over geneve IPv6 tunnels (and vice versa), and still fixes the uninit-value bug fixed by the original commit.

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.
