Anoop Saldanha 8cf60d6645 Changed the way cuda dispatcher passes back results. Now each detection thread has it's own queue to which the dispatcher can pump packets back to the detect thread. Also, with cuda enabled and a non-cuda mpm being used, we won't create a dispatcher and instead call the b2g scan/search funtions directly instead of using the dispatcher. 16 years ago
Anoop Saldanha c26e92733d handle the cuda cleanup at shutdown. should get rid of any errors from the call to SigGroupCleanup 16 years ago

Jason Ish e87d4f8a28 Split the defrag counters into ipv4 and ipv6. 16 years ago
Jason Ish 6b562f7aa6 Issue 82 - fragment counters. - number of fragments - number reassembled - number of timeouts 16 years ago
Pierre Chifflier 4515ae13e4 Add Prelude output plugin 
Add support for reporting alerts to the Prelude SIEM system, using
libprelude to send IDMEF (RFC4765) messages.

Each message contains the alert description and reference (using
the SID/GID), and a normalized description (assessment, impact,
sources etc.)

libprelude handles the connection with the manager (collecting component),
spooling and sending the event asynchronously. It also offers transport
security (using TLS and trusted certificates) and reliability (events
are retransmitted if not sent successfully).

This modules requires a Prelude profile to work (see man prelude-admin
and the Prelude Handbook for help).

Pablo Rincon 51dc773eec Changing the veredict actions to flags to allow simultaneous veredict 16 years ago
Jason Ish 7d920a1254 Fix issue 65. 
- Update unit test to trigger the failure found in the issue 65 pcap.
- Increase pkt buffer to account for the IPv6 header, as a maximum
  size IPv6 datagram is 40 + 0xffff.
- Account for IPv4 header when checking where end of fragment lies.
- Second sanity check during re-assembly to check for writing past
  the end of the pkt buffer.
 16 years ago
Jason Ish 5076452707 Potential fix for issue 60. 
- Increase the packet buffer so it can hold the link header when we
  have maximum size IP datagrams.
- Fix ip header length and pkt length calculation for re-assembled
  packets.

Victor Julien 4824868766 Application layer detection improvements 
- improve locking of application layer handling, making sure that the flow cannot be freed/cleared when the detection engine is still working with it.
- add a check to the app layer detection to make sure that a match function will only inspect an app layer state if it's of the right type.
