[ Upstream commite16b859872] The MACVLAN receive handler clones skbs to all matching source MACVLAN interfaces, before it passes the packet along to match on destination based MACVLANs. When using the MACVLAN nodst mode, passing the packet to destination based MACVLANs is omitted and the handler returns with RX_HANDLER_CONSUMED. However, the passed skb is not freed, leaking for any packet processed with the nodst option. Properly free the skb when consuming packets to fix that leak.

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.
