net: l3mdev: Support for sockets bound to enslaved device
A missing piece to the VRF puzzle is the ability to bind sockets to
devices enslaved to a VRF. This patch set adds the enslaved device
index, sdif, to IPv4 and IPv6 socket lookups. The end result for users
is the following scope options for services:
1. "global" services - sockets not bound to any device
Allows 1 service to work across all network interfaces with
connected sockets bound to the VRF the connection originates
(Requires net.ipv4.tcp_l3mdev_accept=1 for TCP and
net.ipv4.udp_l3mdev_accept=1 for UDP)
2. "VRF" local services - sockets bound to a VRF
Sockets work across all network interfaces enslaved to a VRF but
are limited to just the one VRF.
3. "device" services - sockets bound to a specific network interface
Service works only through the one specific interface.
v3
- convert __inet_lookup_established in dccp_v4_err; missed in v2
v2
- remove sk_lookup struct and add sdif as an argument to existing
functions
Changes since RFC:
- no significant logic changes; mainly whitespace cleanups

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
