Xin Long says: ==================== tipc: fix the mtu update in link mtu negotiation This patchset fixes a crash caused by a too small MTU carried in the activate msg. Note that as such malicious packet does not exist in the normal env, the fix won't break any application The 1st patch introduces a function to calculate the minimum MTU for the bearer, and the 2nd patch fixes the crash with this helper. While at it, the 3rd patch fixes the udp bearer mtu update by netlink with this helper. ==================== Reviewed-by: Tung Nguyen <tung.q.nguyen@dektech.com.au> 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.
