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
Feature: #5479
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.
Task #5503
Add a line to the configuration that says which version generated the
configuration file. For example:
# This configuration generated by:
# Suricata 7.0.0-dev
Issue: #4784
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.
Conf Bug#4941
Task #4207
max-streams and max-table-size
Allows users to find balance between completeness of decoding
and increases resource consumption, which can DOS suricata.
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Remove old outdated comments/commented code from FindUrlStrings.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.

- add nom parsers for decoding most messages from StartupPhase and
SimpleQuery subprotocols
- add unittests
- tests/fuzz: add pgsql to confyaml
Feature: #4241
This commit adds a configuration setting to enable a stack trace message
if Suricata receives a signal that terminates execution, such as
SIGSEGV, SIGABRT.
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.
Simplify locking by using the THashData lock instead of a separate
range lock.
Avoid size_t in function arguments.
Clean up file handling functions.
Implement handling of alloc errors.
Rename yaml entry to byterange
Unify public api naming
adds a container, ie a thread safe hash table whose
key is the filename
keep a tree of unordered ranges, up to a memcap limit
adds HTPFileOpenWithRange to handle like HTPFileOpen
if there is a range : open 2 files, one for the whole reassembled,
and one only for the current range
We add a new 'mqtt.(un)subscribe-topic-match-limit' option
to allow a user to specify the maximum number of topics in
a MQTT SUBSCRIBE or UNSUBSCRIBE message to be evaluated
in detection.
Renaming was done with shell commands, git mv for moving the files and content like
find -iname '*.c' | xargs sed -i 's/ikev1/ike/g' respecting the different mixes of upper/lower case.
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
load: datasets.csv
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.
This commit modifies the JSON loggers with changes necessary to support
multi-threaded EVE output.
Each "thread-init" function sets up the per-thread log file context for
subsequent calls to the JSON output to buffer function.
