This patch introduces the ebpf cluster mode. This mode is using
an extended BPF function that is loaded into the kernel and
provide the load balancing.
An example of cluster function is provided in the ebpf
subdirectory and provide ippair load balancing function.
This is a function which uses the same method as
the one used in autofp ippair to provide a symetrical
load balancing based on IP addresses.
A simple filter example allowing to drop IPv6 is added to the
source.
This patch also prepares the infrastructure to be able to load
and use map inside eBPF files. This will be used later for flow
bypass.
Use a new directory, Python to host the Suricata python modules.
One entry point is suricatactl, a control script for
miscalleneous tasks. Currently onl filestore pruning
is implemented.
Add option to put Rust code in non-'--release' mode, preserving
debug symbols.
Until now Suricata would have to be compiled with --enable-debug for
this.
This patch adds support for hw bypass by enabling flow offload in the network
card (when supported) and implementing the BypassPacketsFlow callback.
Hw bypass support is disabled by default, and can be enabled by setting
"bypass: yes" in the pfring interface configuration section in suricata.yaml.
During configure, substitute the path of cargo, as well as the
value of CARGO_HOME as variables. This fixes the case where a
user might do:
make
sudo make install
Which will cause the cargo bits to be rebuilt, including
re-downloading external crates.
By saving these to variables we can be sure that the same
values are used during make install as were used during
make which prevents the Rust artifacts from being rebuild
during "sudo make install".
Rust is currently optional, use the --enable-rust configure
argument to enable Rust.
By default Rust will be built in release mode. If debug is enabled
then it will be built in debug mode.
On make dist, "cargo vendor" will be run to make a local copy
of Rust dependencies for the distribution archive file.
Add autoconf checks to test for the vendored source, and if it
exists setup the build to use the vendored code instead of
fetching it from the network.
Also, as Cargo requires semantic versioning, the Suricata version
had to change from 4.0dev to 4.0.0-dev.
eve: detects libevent for async redis at configure
eve: moves redis output code to new file - util-log-redis.{c,h}
eve: redis ECHO and QUIT commands for async mode
eve: redis output defaults if conf is missing
The new Hyperscan 4.4 API provides a function to check for SSSE3
presence at runtime. This allows us to fall back to non-Hyperscan
matchers on systems without SSSE3 even when the suricata executable
is built with Hyperscan support. Addresses Redmine issue #2010.

On start, look for existing pcap log files and add them to
the ring buffer. This makes pcap-log self maintaining over
restarts removing the need for external tools to clear
orphaned files.
