it.
 14 years ago
Eric Leblond a85dc9b0e2 Add support for replace keyword. 
This patch adds support for the replace keyword. It is used with
content to change selected part of the payload. The major point
with this patch is that having a replace keyword made necessary
to avoid all stream level check because we need to access to the
could-be-modified packet payload.

One of the main difficulty is to handle complex signature. If there is
other content check, we must do the substitution when we're sure all
match are valid. The patch adds an attribute to the thread context
variable to be able to deal with recursivity of the match function.

Replace is only activated in IPS mode and apply only to raw match.

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

Eric Leblond 9beebf621a Add support for 'nfq_set_mark' keyword 
This patch introduces 'nfq_set_mark' which is new rules option. If a packet
matches a rule using nfq_set_mark in NFQ mode, it is marked with the mark/mask
specified in the option during the verdict.
It is thus possible to trigger different behaviour on the packet inside
Linux/Netfilter.

Eric Leblond 49adc264bc Don't print message after SCMalloc failure. 
This patch generated via coccinelle is getting rid of logging
message after a SCMalloc failure. They were useless as SCMalloc
already displays a message.
 15 years ago
Eric Leblond 1db4aadd16 Supress usage of Packet declaration in tests. 
For convenience, a massive usage of 'Packet p;' declaration has
been done in the tests function. Although this was completely
legal, this is not possible anymore because of the new Packet
allocation structure. This massive patch modifies all suricata
files to use a SCMalloc allocated pointer to Packet instead.

This patch has been done using coccinelle (http://coccinelle.lip6.fr)
which is a semantic patching tool. This ensures that things like call
to SCFree() should have not been forget because the semantic patch
explicitly forces the call to SCFree(p) before each return. With this
patch all unittests are running fine with a small and a big default
packet size.

Victor Julien 70b32f7380 First stab at creating a stateful detection engine. 
Stateful detection for app layer detection keywords, except uricontent. Stores it's partial results in the flow structure. Other modifications:

- Adapt http and dcerpc to use the new transaction handling.
- Stream engine now always notifies app layer of a stream eof.

- stream engine uses a memcap setting. Sessions, segments and aldata is part
  of this, app layer state isn't.
- memory is accounted using a global int that is spinlocked.
- a counter for sessions that have not been picked up because of memcap was
  added.
- all reassembly errors are converted to debug msgs.
