This patch adds the capabilities to log the TLS information the
same way it is currently possible to do with HTTP. As it is
quite hard to read ASN.1 directly in the stream, this will help
people to understand why suricata is firing on alert relative
to TLS.
The option sets in bytes the value at which segment data is passed to
the app layer API directly. Data sizes equal to and higher than the
value set are passed on directly.
Default is 128.
- Added the suricata.yaml configurations and updated the comments
- Renamed the field in the configuration structure to something generic
- Added two new constants and the warning codes
- Created app-layer-htp-xff.c and app-layer-htp-xff.h
- Added entries in the Makefile.am
- Added the necessary configuration options to EVE alert section
- Updated Unified2 XFF configuration comments and removed unnecessary whitespace
- Created a generic function to parse the configuration
- Release the flow locks sooner and remove debug logging
- Added XFF support to EVE alert output
Add a new default value for the 'threads:' setting in af-packet: "auto".
This will create as many capture threads as there are cores.
Default runmode of af-packet to workers.
As the stats api calls the loggers at a global interval, the global
interval should be configured globally.
# global stats configuration
stats:
enabled: yes
# The interval field (in seconds) controls at what interval
# the loggers are invoked.
interval: 8
If this config isn't found, the old config will be supported.
Decode Modbus request and response messages, and extracts
MODBUS Application Protocol header and the code function.
In case of read/write function, extracts message contents
(read/write address, quantity, count, data to write).
Links request and response messages in a transaction according to
Transaction Identifier (transaction management based on DNS source code).

Add option (disabled by default) to honor pass rules. This means that
when a pass rule matches in a flow, it's packets are no longer stored
by the pcap-log module.
Use new management API to run the flow recycler.
Make number of threads configurable:
flow:
memcap: 64mb
hash-size: 65536
prealloc: 10000
emergency-recovery: 30
managers: 2
recyclers: 2
This sets up 2 flow recyclers.
Use new management API to run the flow manager.
Support multiple flow managers, where each of them works with it's
own part of the flow hash.
Make number of threads configurable:
flow:
memcap: 64mb
hash-size: 65536
prealloc: 10000
emergency-recovery: 30
managers: 2
This sets up 2 flow managers.
Handle misc tasks only in instance 1: Handle defrag hash timeout
handing, host hash timeout handling and flow spare queue updating
only from the first instance.
Now that we use 'filetype' instead of 'type', we should also
use 'regular' instead of 'file'.
Added fallback to make sure we stay compatible to old configs.
EVE logging is a really good substitute for pcapinfo. Suriwire is
now supporting EVE output so it is not anymore necessary to have
pcapinfo in Suricata.
Add profiling to a logfile. Default is $log_dir/pcaplog_stats.log
The counters for open, close, rotate, write and handles are written
to it, as well as:
- total bytes written
- cost per MiB
- cost per GiB
Option is disabled by default.
Instead of the notion of toserver and toclient protocol detection, use
destination port and source port.
Independent of the data direction, the flow's port settings will be used
to find the correct probing parser, where we first try the dest port,
and if that fails the source port.
Update the configuration file format, where toserver is replaced by 'dp'
and toclient by 'sp'. Toserver is intrepreted as 'dp' and toclient as
'sp' for backwards compatibility.
Example for dns:
dns:
# memcaps. Globally and per flow/state.
#global-memcap: 16mb
#state-memcap: 512kb
# How many unreplied DNS requests are considered a flood.
# If the limit is reached, app-layer-event:dns.flooded; will match.
#request-flood: 500
tcp:
enabled: yes
detection-ports:
dp: 53
udp:
enabled: yes
detection-ports:
dp: 53
Like before, progress of protocol detection is tracked per flow direction.
Bug #1142.
Add option "profiling.sample-rate":
# Run profiling for every xth packet. The default is 1, which means we
# profile every packet. If set to 1000, one packet is profiled for every
# 1000 received.
#sample-rate: 1000
This allows for configuration of the sample rate.
