A CAP_NET_RAW capable process can already spoof (on transmit) anything it desires via raw packet sockets... There is no good reason to not allow it to also be able to play routing tricks on packets from its own normal sockets. There is a desire to be able to use SO_MARK for routing table selection (via ip rule fwmark) from within a user process without having to run it as root. Granting it CAP_NET_RAW is much less dangerous than CAP_NET_ADMIN (CAP_NET_RAW doesn't permit persistent state change, while CAP_NET_ADMIN does - by for example allowing the reconfiguration of the routing tables and/or bringing up/down devices). Let's keep CAP_NET_ADMIN for persistent state changes, while using CAP_NET_RAW for non-configuration related stuff.

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.
