User space may pass non-nul-terminated NFTA_DEVICE_NAME attribute values to indicate a suffix wildcard. Expect for multiple devices to match the given prefix in nft_netdev_hook_alloc() and populate 'ops_list' with them all. When checking for duplicate hooks, compare the shortest prefix so a device may never match more than a single hook spec. Finally respect the stored prefix length when hooking into new devices from event handlers. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
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 reStructuredText 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.
