The existing code is functionally correct: iproute2 parses the ip_flags argument for tc-flower and really packs it as big endian into the TCA_FLOWER_KEY_FLAGS netlink attribute. But there is a problem in the fact that W=1 builds complain: net/sched/cls_flower.c:1047:15: warning: cast to restricted __be32 This is because we should use the dedicated helper for obtaining a __be32 pointer to the netlink attribute, not a u32 one. This ensures type correctness for be32_to_cpu. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
