[ Upstream commit5eea3a63ff] ie., $ ifconfig eth0 6.6.6.6 netmask 255.255.255.0 $ ip rule add from 6.6.6.6 table 6666 $ ip route add 9.9.9.9 via 6.6.6.6 $ ping -I 6.6.6.6 9.9.9.9 PING 9.9.9.9 (9.9.9.9) from 6.6.6.6 : 56(84) bytes of data. 3 packets transmitted, 0 received, 100% packet loss, time 2079ms $ arp Address HWtype HWaddress Flags Mask Iface 6.6.6.6 (incomplete) eth0 The arp request address is error, this is because fib_table_lookup in fib_check_nh lookup the destnation 9.9.9.9 nexthop, the scope of the fib result is RT_SCOPE_LINK,the correct scope is RT_SCOPE_HOST. Here I add a check of whether this is RT_TABLE_MAIN to solve this problem.

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.
