When multiple containers are running in the environment and multiple macvlan network port are configured in each container, a lot of martian source prints will appear after martian_log is enabled. they are almost the same, and printed by net_warn_ratelimited. Each arp message will trigger this print on each network port. Such as: IPv4: martian source 173.254.95.16 from 173.254.100.109, on dev eth0 ll header: 00000000: ff ff ff ff ff ff 40 00 ad fe 64 6d 08 06 ......@...dm.. IPv4: martian source 173.254.95.16 from 173.254.100.109, on dev eth1 ll header: 00000000: ff ff ff ff ff ff 40 00 ad fe 64 6d 08 06 ......@...dm.. There is no description of this kind of source in the RFC1812. Signed-off-by: Zhang Yunkai <zhang.yunkai@zte.com.cn> 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.
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.
