Anoop Saldanha 17c763f855 Version 1 of AC Cuda. 12 years ago
Anoop Saldanha 2de59fc235 Version 1 of CudaBuffer API. Introduced to buffer data to the gpu. 
This version allows async writes to a buffer by threads.  Allows only
sequential reads though.
 12 years ago
Anoop Saldanha 557cab3dc9 We call packet and stream mpm as late as possible now. Won't affect the working of the engine. 
The rationale behind this is, if we have pkt buffered to the gpu, we'd want
to delay processing the pkt as much as possible.

Direct access to the action field of Packet structure is not
allowed.
 12 years ago
Eric Leblond a35c367942 action handling: use macro for test. 
Use test macro instead of direct access to action field.

This patch has been obtained by using the following
spatch file:

  - p->action & E

Eric Leblond efaa9a7302 action handling: define and use macros 
The action field in Packet structure should not be accessed
directly as the tunneled packet needs to update the root packet
and not the initial packet.

This patch is fixing issue #819 where suricata was not able to
drop fragmented packets in AF_PACKET IPS mode. It also fixes
drop capability for tunneled packets.

Anoop Saldanha ff222b51e7 Http trailer headers unittests added. 12 years ago
Anoop Saldanha ab4b15c2e7 fix for #788. 
Now depth is kept in mind when we inspect chunks in client/server body.
This takes care of FPs originating from inspecting subsequent chunks that
match with depth, but shouldn't.

Victor Julien f29e5459e6 luajit/flowint: add ScFlowintIncr & ScFlowintDecr 
Add flowint lua functions for incrementing and decrementing flowints.

First use creates the var and inits to 0. So a call:

    a = ScFlowintIncr(0)

Results in a == 1.

If the var reached UINT_MAX (2^32), it's not further incremented. If the
var reaches 0 it's not decremented further.

Calling ScFlowintDecr on a uninitialized var will init it to 0.

Example script:

    function init (args)
        local needs = {}
        needs["http.request_headers"] = tostring(true)
        needs["flowint"] = {"cnt_incr"}
        return needs
    end

    function match(args)
        a = ScFlowintIncr(0);
        if a == 23 then
            return 1
        end

        return 0
    end
    return 0

This script matches the 23rd time it's invoked on a flow.

Victor Julien f312486c6e flowvar/luajit: make 'sets' real time. Needed for cross HTTP-header matching. 12 years ago
Victor Julien 72f6bc2aed luajit: add flowint support 
Expose ScFlowintGet and ScFlowintSet functions to luajit. These set
flowints in real time, regardless of rule and/or script match.

Example:

function init (args)
    local needs = {}
    needs["http.request_headers"] = tostring(true)
    needs["flowint"] = {"cnt"}
    return needs
end

function match(args)
    a = ScFlowintGet(0);
    if a then
        ScFlowintSet(0, a + 1)
    else
        ScFlowintSet(0, 1)
    end

    a = ScFlowintGet(0);
    if a == 23 then
        return 1
    end

    return 0
end

return 0

Script's init call first registers "cnt" at id 0, then 0 is used to use
this var.

Victor Julien 6e18ed0489 luajit flowvar support 
This patch adds flowvar support to luajit. It does so by exposing two special
C functions to the luajit scripts: ScFlowvarGet and ScFlowvarSet.

Ken Steele 9d677ea006 Clear the PKT_ALLOC flag when storing Packets into the Packet pool. 
The PKT_ALLOC flag is set by PacketGetFromAlloc(), which needs to be
cleared for Packets in the Packet Pool, so clear the flag here.

Anoop Saldanha ab1f8afbc3 Removed Signature->order_id and replaced it with Signature->num. 12 years ago
Anoop Saldanha 43d1229dfa 1. Fix assignment of signums, which affected how we used read 
sigs(priority wise) inside staging.

   Previously we would assign signums before sig ordering, and hence the
   order didn't actually reflect the order of the sig in the
   sig_list(assuming sig reordering changed the sig_list).  Staging would
   use the old sig_nums to decide the priority of sigs.
2. Fix sig ordering for flowvar, flowbits, flowint, pktvar sigs.   We have
   introduced a new priority to treat sigs with set + read as lower
   priority compared to set only sigs.
3. Previously we treated sigs with a "priority(keyword)" > another sig's
   priority, as a sig with greater priority than the later.  We have
   reversed it.  Now the sig priority ordering is 1,2,.etc.  Updated
   sigordering unittests to reflect the same.

Anoop Saldanha 9219079e1a Allow protocols to have both app layer keywords, as well as transaction
