Victor Julien 77b7089f79 Fix stream-events not working. Stream events won't fit our 'detection only' schema. Fixes #321. 14 years ago
pilcrow f5017e0d1a Always try PCRE_NO_AUTO_CAPTURE first for signature regexes. 
Many, many pcre: signatures specify (...) when the more efficient
(?:...) is all that is needed.  This change attempts to force
PCRE_NO_AUTO_CAPTURE on all unnamed capture groups, reverting to
capturing when necessary, e.g., when \1 is referenced.

Eric Leblond 7425bf5ca6 Rename some decode event structure and macro. 
This patch renames DECODER_SET_EVENT, DECODER_ISSET_EVENT and some
other structures to ENGINE equivalent to take into account the fact
the event list is now related to all engines and not only to decoder.
 14 years ago
Eric Leblond de65b11c42 decode signature optimisation requires different treatment 
Decode signature are using the fact that no proto is set on packet
to increase the matching speed. This is not the case of stream and
other engine events. Thus a difference needs to be made.
 14 years ago
Eric Leblond 3f153fb0da Add 'stream-event' keyword. 
This patch adds an alias to the 'engine-event' keyword. It is now
possible to access to the stream events via the 'stream-event'
keyword. A simple transformation is done:
    stream-event:reassembly_segment_before_base_seq
is a shortcut for:
    engine-event:stream.reassembly_segment_before_base_seq
 14 years ago

Eric Leblond 834c91eece af-packet: add AFP to per packet performance system. 14 years ago
Eric Leblond fb4be6199f af-packet: change option name 
This patch changes the option name. af-packet long option is
now used instead of -a to mimic pfring behaviour.

This patch improves the standard parsing of the command line.
Running
 suricata -c suricata.yaml --af-packet
will start a suricata running in AF_PACKET mode listening on all
interfaces defined in the suricata.yaml configuration file. The
traditionnal syntax:
 suricata -c suricata.yaml --af-packet=ppp0
will start a suricata listening on ppp0 only.
 14 years ago
Eric Leblond e253da092c device: Add function to build interface list from config 
This patch adds a new function which build the list of interfaces to
use by parsing the configuration file. This is using the new format
and thus only af-packet can benefit of this feature.
 14 years ago
Eric Leblond df7dbe36b6 af-packet: Add option to disable promiscuous mode 
This patch adds an option to suricata.yaml to be able to disable
the switch of the interface into promiscuous mode.
 14 years ago
Eric Leblond fbca1a4e6b af-packet: multi interface support 
This patch adds multi interface support to AF_PACKET. A structure
is used at thread creation to give all needed information to the
input module. Parsing of the options is done in runmode preparation
through a dedicated function which return the configuration in a
structure usable by thread creation.
 14 years ago
Eric Leblond dc667af1a1 conf: Introduce new function to input configuration. 
The input modules are needing a per interface configuration. This
implies some new operations to be able to parse easily te configuration.

The syntax of the configuration file is for example:
af-packet:
  - interface: eth0
    threads: 2
  - interface: eth1
    threads: 3
We need a way to express get a configuration variable for interface[eth0].
This is by using ConfNodeLookupKeyValue() to get the matching node. And
after that value can be fetch by using ConfGetChildValue*() functions.

Eric Leblond e80b30c082 af-packet: finalize code 
This patch handles the end of AF_PACKET socket support work. It
provides conditional compilation, autofp and single runmode.

It also adds a 'defrag' option which is used to activate defrag
support in kernel to avoid rx_hash computation in flow mode to fail
due to fragmentation.

This patch contains some fixes by Anoop Saldanha, and incorporate
change following review by Anoop Saldanha and Victor Julien.

AF_PACKET support is only build if the --enable-af-packet flag is
given to the configure command line. Detection of code availability
is also done: a check of the existence of AF_PACKET in standard
header is done. It seems this variable is Linux specific and it
should be enough to avoid compilation of AF_PACKET support on other
OSes.
Compilation does not depend on up-to-date headers on the system. If
none are present, wemake our own declaration of FANOUT variables. This
will permit compilation of the feature for system where only the kernel
has been updated to a version superior to 3.1.

They are not specific to pcap and could thus be used in other module.

Victor Julien fca541f40e Add per app layer parser profiling 
Per packet per app layer parser profiling. Example summary output:

Per App layer parser stats:

App Layer              IP ver   Proto   cnt        min      max          avg
--------------------   ------   -----   ------     ------   ----------   -------

Also added to the csv out.

In the csv out there is a new column "stream (no app)" that removes the
app layer parsers from the stream tracking. So raw stream engine performance
becomes visible.

Victor Julien 0cc9f39200 Move TlsConfig structure out of app-layer-protos.h and rename it to SslConfig. 14 years ago
Victor Julien 820b0ded82 Add per packet profiling. 
Per packet profiling uses tick based accounting. It has 2 outputs, a summary
and a csv file that contains per packet stats.

Stats per packet include:
 1) total ticks spent
 2) ticks spent per individual thread module
 3) "threading overhead" which is simply calculated by subtracting (2) of (1).

A number of changes were made to integrate the new code in a clean way:
a number of generic enums are now placed in tm-threads-common.h so we can
include them from any part of the engine.

Code depends on --enable-profiling just like the rule profiling code.

New yaml parameters:

profiling:
  # packet profiling
  packets:

    # Profiling can be disabled here, but it will still have a
    # performance impact if compiled in.
    enabled: yes
    filename: packet_stats.log
    append: yes

    # per packet csv output
    csv:

      # Output can be disabled here, but it will still have a
      # performance impact if compiled in.
      enabled: no
      filename: packet_stats.csv

Example output of summary stats:

IP ver   Proto   cnt        min      max          avg
------   -----   ------     ------   ----------   -------
 IPv4       6     19436      11448      5404365     32993
 IPv4     256         4      11511        49968     30575

which are rather small and thus should not be a performance and security
issue.
