Jaehee Park says: ==================== net: ipv4/ipv6: new option to accept garp/untracked na only if in-network The first patch adds an option to learn a neighbor from garp only if the source ip is in the same subnet as an address configured on the interface that received the garp message. The option has been added to arp_accept in ipv4. The same feature has been added to ndisc (patch 2). For ipv6, the subnet filtering knob is an extension of the accept_untracked_na option introduced in these patches: https://lore.kernel.org/all/642672cb-8b11-c78f-8975-f287ece9e89e@gmail.com/t/ https://lore.kernel.org/netdev/20220530101414.65439-1-aajith@arista.com/T/ The third patch contains selftests for testing the different options for accepting arp and neighbor advertisements. ==================== Link: https://lore.kernel.org/r/cover.1657755188.git.jhpark1013@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
