![]() When there exist a pair of raw sockets one unbound and one bound to a VRF but equal in all other respects, when a packet is received in the VRF context, __raw_v4_lookup() matches on both sockets. This results in the packet being delivered over both sockets, instead of only the raw socket bound to the VRF. The bound device checks in __raw_v4_lookup() are replaced with a call to raw_sk_bound_dev_eq() which correctly handles whether the packet should be delivered over the unbound socket in such cases. In __raw_v6_lookup() the match on the device binding of the socket is similarly updated to use raw_sk_bound_dev_eq() which matches the handling in __raw_v4_lookup(). Importantly raw_sk_bound_dev_eq() takes the raw_l3mdev_accept sysctl into account.

README
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.
