The default value for the mask actually depends on the value (e.g: if the value is non-null, the default is full-mask), so change the convert functions to accept the full, possibly masked string and let them figure out how to parse the different values. Also, implement size-aware int parsing. With this patch we can now express flows such as the following: "eth(src=0a:ca:fe:ca:fe:0a/ff:ff:00:00:ff:00)" "eth(src=0a:ca:fe:ca:fe:0a)" -> mask = ff:ff:ff:ff:ff:ff "ipv4(src=192.168.1.1)" -> mask = 255.255.255.255 "ipv4(src=192.168.1.1/24)" "ipv4(src=192.168.1.1/255.255.255.0)" "tcp(src=8080)" -> mask = 0xffff "tcp(src=8080/0xf0f0)" Signed-off-by: Adrian Moreno <amorenoz@redhat.com> Acked-by: Aaron Conole <aconole@redhat.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
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.
