David Ahern says: ==================== net: Fix looping with vrf, xfrms and qdisc on VRF Trev reported that use of VRFs with xfrms is looping when a qdisc is added to the VRF device. The combination of xfrm + qdisc is not handled by the VRF driver which lost track that it has already seen the packet. The XFRM_TRANSFORMED flag is used by the netfilter code for a similar purpose, so re-use for VRF. Patch 1 drops the #ifdef around setting the flag in the xfrm output functions. Patch 2 adds a check to the VRF driver for flag; if set the packet has already passed through the VRF driver once and does not need to recirculated a second time. This is a day 1 bug with VRFs; stable wise, I would only take this back to 4.14. I have a set of test cases which I will submit to net-next. ==================== Signed-off-by: David S.

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.
