This test covers functionality and stability of the newly added nftables set implementation supporting concatenation of ranged fields. For some selected set expression types, test: - correctness, by checking that packets match or don't - concurrency, by attempting races between insertion, deletion, lookup - timeout feature, checking that packets don't match expired entries and (roughly) estimate matching rates, comparing to baselines for simple drop on netdev ingress hook and for hash and rbtrees sets. In order to send packets, this needs one of sendip, netcat or bash. To flood with traffic, iperf3, iperf and netperf are supported. For performance measurements, this relies on the sample pktgen script pktgen_bench_xmit_mode_netif_receive.sh. If none of the tools suitable for a given test are available, specific tests will be skipped. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> 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 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.
