Philippe Antoine a003640ecf security: prevents process creation
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.

Eric Leblond 485d5a4ea4 landlock: basic implementation
This patch is adding support for Landlock, a Linux
Security Module available since Linux 5.13.

The concept is to prevent any file operation on directories where
Suricata is not supposed to access.

Landlock support is built by default if the header is present. The
feature is disabled by default and need to be activated in the YAML
to be active.

Landlock documentation: https://docs.kernel.org/userspace-api/landlock.html

Juliana Fajardini bbd968c738 exceptions: add reject support to exception policy
This enables the usage of 'reject' as an exception policy. As for both
IPS and IDS modes the intended result of sending a reject packet is to
reject the related flow, this will effectively mean setting the reject
action to the packet that triggered the exception condition, and then
dropping the associated flow.

Jason Ish b5d1a80002 suricata.yaml: include version that generated this file
Add a line to the configuration that says which version generated the

Juliana Fajardini 3ace577d54 decode: make packet_alert_max configurable
The maximum of possible alerts triggered by a unique packet was
hardcoded to 15. With usage of 'noalert' rules, that limit could be
reached somewhat easily. Make that configurable via suricata.yaml.

Aaron Bungay 272786908c smtp/mime: configurable url scheme extraction
Parse extract-url-schemes from the mime config.
e.g. 'extract-urls-schemes: [http, https, ftp, mailto]'
Update MimeDecConfig struct to new url extraction fields.
Change app-layer-smtp.c & util-decode-mime.c to initialize new struct
fields for MimeDecConfig.
Sets the default value for extract-url-schemes if not found in the
config to 'extract-urls-schemes: [http]' for backwards compatibility.

Uses the schemes defined in the mime config value for
extract-urls-schemes to search for URLS starting with those scheme
names followed by "://".
Logs the URLS with the scheme + '://' at the start if the
log-url-scheme is set in the mime config, otherwise the old behaviour
is reverted to and the urls are logged with the schemes stripped.

Removed unused constant URL_STR now that URLS are being searched for
using extract-urls-schemes mime config values instead of just URL's
starting with 'http://'.

Added commented out new options for extract-urls-schemes and
log-url-scheme to suricata.yaml.in.

Update FindUrlStrings comments.
Remove old outdated comments/commented code from FindUrlStrings.
Update test case for mime which now needs schemes list to be set.
Add Test Cases for FindUrlStrings() method.

Lukas Sismis a7faed1245 dpdk: initial support with workers runmode
Register a new runmode - DPDK. This enables a new flag on Suricata start
(--dpdk).

With the flag given, DPDK runmode is enabled.

Runmode loads the configuration and then initializes EAL.

If successful, it configures the physical NICs according to the configuration
file. After that, worker threads are initialized and then are in continuous
receive loop.

Shivani Bhardwaj 1286b0a8f1 datasets: parse defaults section from yaml
Datasets can now have a global defaults setting in suricata.yaml. In
case the settings for memcap and hashsize are not find in the yaml or
rule, this shall be the fallback.

Example:

datasets:
  defaults:
    memcap: 100mb
    hashsize: 2048
  ua-seen:
    type: string

Sascha Steinbiss 4e1a41a17d output-json: add MAC address output
This commit adds MAC address output to the EVE-JSON format. We follow the
remarks made in Redmine ticket #962: for packets, log MAC src/dst as a
scalar field in EVE; for flows, log MAC src/dst as lists in EVE. Field names
are different between flow and packet context to avoid type confusion
(src_mac vs. src_macs). Configuration approach and JSON representation is
taken from previous GitHub PR #2700.
