Addresses this warning from the Rust compiler:
warning: `../rust/.cargo/config` is deprecated in favor of `config.toml`
note: if you need to support cargo 1.38 or earlier, you can symlink `config` to `config.toml`
(cherry picked from commit 8560564657)
In worktree scenarios, .git is a file. Assuming its a directory causes
the release date to check the ChangeLog instead of the last commit,
while not a big issue, can be confusing.
Sphinx embeds a date in the generated man pages, and to provide
reproducible builds this date needs to be provided to Sphinx,
otherwise it will use the current date.
If building from Git, extract the date from the most recent commit. In
a release, this commit would be the commit that sets the version so is
accurate.
If .git does not exist, use the most recent data found in the
ChangeLog.
The ChangeLog is not used when building from git, as the main/master
branch may not have recent enough timestamps.
This should provide a consistent date when re-building the
distribution from the same non-git archive, or from the same git
commit.

If a user allocates too many hugepages and those are largely not used
then Suricata suggests that the user can lower the amount of hugepages
and therefore save memory for other purposes.
Ticket: #5966
- Use SPHINX_BUILD instead of HAVE_SPHINX_BUILD, as here we're
actually using the path of the program.
- Wrap some elements in [] as is done in modern idiomatic autoconf
We need a recent version of Sphinx to build the documentation in
7.0. Check for a minimum version of 3.4.3. If older, do not build the
docs which is the same behavior when sphinx-build is not found.
Bug: #6297
On installation, make sure the data directory is created. This will
usually be /var/lib/suricata/data, but otherwise follows the
autoconf/automake instructions.
This directory is for runtime state information, which for now is
datasets but may be expanded in the future. Suricata already expects
this directory to exist for "state" and "save" datasets, but it has
been up to the user to create it.
Rust 1.70 has introduced some possible issues between LLVM and gcc
causing link errors that are fixed by explicitly adding -lntdll.
Thanks to https://github.com/extendr/rextendr/pull/285 for the fix.
Header checking (AC_CHECK_HEADER) did not work as
DPDK 19.11 included rte_eth_bond.h file even if net/bonding
driver was disabled. However, it was still not available in
ldconfig configuration. For this reason Bond PMD is checked with
ldconfig tool.
However when installing the DPDK library manually, the user needs to
update the entries in ldconfig to be able to find the Bond PMD.
Ticket: #6099
Performance measurement of rules is important on live Suricata
as bad rules can cause severe performance regression. This patch
introduces the --enable-profiling-rules that activate profiling
for the rules. This reduces the performance impact of full
profiling and provide visiblity on the rules performance at
the same time.
Cargo.lock has to be provided as template, Cargo.lock.in so it can
live beside Cargo.lock in out of tree automake builds, like distcheck.
This will pin Rust dependencies even for git builds, updating
Cargo.lock will now be a manual process that we'll have to take care
of periodically.
libbpf 0.8 deprecates bpf_get_link_xpd_id, and 1.0 removes it. Add
./configure check to see if this method is available and use it if so,
otherwise use the deprecated method which is not available on older
but still supported Linux distributions.
Ticket: #5924
Adds a new field, "suricata-version" to the configuration file with
the major and minor version of the Suricata that generated the
configuration file.
This may be useful in the future for presenting warnings about
important changes, or even providing different defaults based on what
the user might expect.

This changeset provides subsystem and module identifiers in the log when
the log format string contains "%S". By convention, the log format
surrounds "%S" with brackets.
The subsystem name is generally the same as the thread name. The module
name is derived from the source code module name and usually consists of
the first one or 2 segments of the name using the dash character as the
segment delimiter.
AF_XDP support is a recent technology introduced that aims at improving
capture performance. With this update, Suricata now provides a new
capture source 'af-xdp' that attaches an eBPF program to the network
interface card. Packets received in the NIC queue are forwarded to
a RX ring in user-space, bypassing the Linux network stack.
Note, there is a configuration option (force-xdp-mode) that forces the
packet through the normal Linux network stack.
libxdp and libbpf is required for this feature and is compile time
configured.
This capture source operates on single and multi-queue NIC's via
suricata.yaml. Here, various features can be enabled, disabled
or edited as required by the use case.
This feature currently only supports receiving packets via AF_XDP,
no TX support has been developed.
Ticket: https://redmine.openinfosecfoundation.org/issues/3306
Additional reading:

with setrlimit NPROC.
So that, if Suricata wants to execve or such to create a new process
the OS will forbid it so that RCE exploits are more painful to write.
Ticket: #5373
Work towards making `suricata-common.h` only introduce system headers
and other things that are independent of complex internal Suricata
data structures.
Update files to compile after this.
Remove special DPDK handling for strlcpy and strlcat, as this caused
many compilation failures w/o including DPDK headers for all files.
Remove packet macros from decode.h and move them into their own file,
turn them into functions and rename them to match our function naming
policy.
