Stefano Brivio says: ==================== ICMP error handling for UDP tunnels This series introduces ICMP error handling for UDP tunnels and encapsulations and related selftests. We need to handle ICMP errors to support PMTU discovery and route redirection -- this support is entirely missing right now: - patch 1/11 adds a socket lookup for UDP tunnels that use, by design, the same destination port on both endpoints -- i.e. VXLAN and GENEVE - patches 2/11 to 7/11 are specific to VxLAN and GENEVE - patches 8/11 and 9/11 add infrastructure for lookup of encapsulations where sent packets cannot be matched via receiving socket lookup, i.e. FoU and GUE - patches 10/11 and 11/11 are specific to FoU and GUE v2: changes are listed in the single patches ==================== 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.
