[ Upstream commit dd72fadf2186fc8a6018f97fe72f4d5ca05df440 ]
In case of xfrm offload, if xdo_dev_state_add() of driver returns
-EOPNOTSUPP, xfrm offload fallback is failed.
In xfrm state_add() both xso->dev and xso->real_dev are initialized to
dev and when err(-EOPNOTSUPP) is returned only xso->dev is set to null.
So in this scenario the condition in func validate_xmit_xfrm(),
if ((x->xso.dev != dev) && (x->xso.real_dev == dev))
return skb;
returns true, due to which skb is returned without calling esp_xmit()
below which has fallback code. Hence the CRYPTO_FALLBACK is failing.
So fixing this with by keeping x->xso.real_dev as NULL when err is
returned in func xfrm_dev_state_add().

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.
