Petr Machata says: ==================== net: ip6_gre: Fixes in headroom handling This series mends some problems in headroom management in ip6_gre module. The current code base has the following three closely-related problems: - ip6gretap tunnels neglect to ensure there's enough writable headroom before pushing GRE headers. - ip6erspan does this, but assumes that dev->needed_headroom is primed. But that doesn't happen until ip6_tnl_xmit() is called later. Thus for the first packet, ip6erspan actually behaves like ip6gretap above. - ip6erspan shares some of the code with ip6gretap, including calculations of needed header length. While there is custom ERSPAN-specific code for calculating the headroom, the computed values are overwritten by the ip6gretap code. The first two issues lead to a kernel panic in situations where a packet is mirrored from a veth device to the device in question. They are fixed, respectively, in patches #1 and #2, which include the full panic trace and a reproducer. The rest of the patchset deals with the last issue. In patches #3 to #6, several functions are split up into reusable parts. Finally in patch #7 these blocks are used to compose ERSPAN-specific callbacks where necessary to fix the hlen calculation. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
