Jakub Sitnicki says: ==================== Don't take HW USO path when packets can't be checksummed by device This series addresses a recent regression report from syzbot [1]. After enabling UDP_SEGMENT for egress devices which don't support checksum offload [2], we need to tighten down the checks which let packets take the HW USO path. The fix consists of two parts: 1. don't let devices offer USO without checksum offload, and 2. force software USO fallback in presence of IPv6 extension headers.

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.
