In commit0146dca70b, I incorrectly adapted the code that computes the location of the UDP or TCP encapsulation header from IPv4 to IPv6. In esp6_input_done2, skb->transport_header points to the ESP header, so by adding skb_network_header_len, uh and th will point to the ESP header, not the encapsulation header that's in front of it. Since the TCP header's size can change with options, we have to start from the IPv6 header and walk past possible extensions.

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.
