Message sends to the local broadcast address (255.255.255.255) require uc_index or sk_bound_dev_if to be set to an egress device. However, responses or only received if the socket is bound to the device. This is overly constraining for processes running in an L3 domain. This patch allows a socket bound to the VRF device to send to the local broadcast address by using IP_UNICAST_IF to set the egress interface with packet receipt handled by the VRF binding. Similar to IP_MULTICAST_IF, relax the constraint on setting IP_UNICAST_IF if a socket is bound to an L3 master device. In this case allow uc_index to be set to an enslaved if sk_bound_dev_if is an L3 master device and is the master device for the ifindex. In udp and raw sendmsg, allow uc_index to override the oif if uc_index master device is oif (ie., the oif is an L3 master and the index is an L3 slave).

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.
