Eric Leblond 4c6595f437 Coverity 1038106: fix FP out-of-bond access
A cast during the reading of a configuration variable was invalid
because a 16 bit integer was cast to a 32 bit integer. The called
function is only setting the pointer value to 1 or 0 so there is
no real issue there.

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 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.

Anoop Saldanha ab1f8afbc3 Removed Signature->order_id and replaced it with Signature->num. 13 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.

Ken Steele 93e7304117 Preserve PKT_ALLOC flag inside PACKET_RECYCLE().

incorrectly.
13 years ago
Ken Steele 699d9e01f1 Move memset() out of PACKET_INITIALIZE()
The memset() inside PACKET_INITIALIZE() is redundant in some cases and
it is cleaner to do as part of the memory allocation. This simplifies
changes for integrating Tilera mPIPE support because the size of memory
cleared in that case is different from SIZE_OF_PACKET.

For the cases where Packets are directly allocated and then call
PACKET_INITIALIZE() without memset() first, this patch adds memset() calls.

A further change would use GetPacketFromAlloc() directly.

Florian Westphal 8da02115c9 nfq: add support for batch verdicts
Normally, there is one verdict per packet, i.e., we receive a packet,
process it, and then tell the kernel what to do with that packet (eg.
DROP or ACCEPT).

recv(), packet id x
send verdict v, packet id x
recv(), packet id x+1
send verdict v, packet id x+1
[..]
recv(), packet id x+n
send verdict v, packet id x+n

An alternative is to process several packets from the queue, and then send
a batch-verdict.

recv(), packet id x
recv(), packet id x+1
[..]
recv(), packet id x+n
send batch verdict v, packet id x+n

A batch verdict affects all previous packets (packet_id <= x+n),
we thus only need to remember the last packet_id seen.

Caveats:
- can't modify payload
- verdict is applied to all packets
- nfmark (if set) will be set for all packets
- increases latency (packets remain queued by the kernel
  until batch verdict is sent).

To solve this, we only defer verdict for up to 20 packets and
send pending batch-verdict immediately if:
- no packets are currently queue
- current packet should be dropped
- current packet has different nfmark
- payload of packet was modified

This patch adds a configurable batch verdict support for workers runmode.
The batch verdicts are turned off by default.

Problem is that batch verdicts only work with kernels >= 3.1, i.e.
using newer libnetfilter_queue with an old kernel means non-working
suricata. So the functionnality has to be disabled by default.
13 years ago
Florian Westphal 6678c9feb9 nfq: avoid extra copy when running in workers mode
currently, the packet payload recv()d from the nfqueue netlink
socket is copied into a new packet buffer.

This is required because the recv-buffer space used is tied
to the current thread, but a packet may be handed off to other
threads, and the recv-buffer can be re-used while the packet
is handled by another thread.

However, in worker runmode, the packet will always be handled
by the current thread, and the recv-buffer will only be reused
after the entire packet processing stack is done with the packet.

Thus, in worker runmode, we can avoid the copy and assign
the packet data area directly.

This patch activates randomization by default and set the random

Victor Julien 4c6463f378 stream: handle extra different SYN/ACK
Until now, when processing the TCP 3 way handshake (3whs), retransmissions
of SYN/ACKs are silently accepted, unless they are different somehow. If
the SEQ or ACK values are different they are considered wrong and events
are set. The stream events rules will match on this.

In some cases, this is wrong. If the client missed the SYN/ACK, the server
may send a different one with a different SEQ. This commit deals with this.

As it is impossible to predict which one the client will accept, each is
added to a list. Then on receiving the final ACK from the 3whs, the list
is checked and the state is updated according to the queued SYN/ACK.

Victor Julien 4cd736fcc9 flowvar: fix deadlock with http buffers
Bug #802

Flowvars are set from pcre, and lock the flow when being set. However
when HTTP buffers were inspected, flow was already locked: deadlock.

This patch introduces a post-match list in the detection engine thread
ctx, where store candidates are kept. Then a post-match function is used
to finalize the storing if the rule matches.

Solves the deadlock and brings the handling of flowvars more in line
with flowbits and flowints.

Eric Leblond 2f0927fe9b pcap: add snaplen YAML variable
This patch introduces 'snaplen' a new YAML variable in the pcap section.

it defaults to interface MTU if MTU can be known via a ioctl call and to
full capture if not.

Eric Leblond 1aaa828b63 pcap: set snaplen to MTU if available.
Main objective of this patch is to use a dynamic snaplen to avoid
to truncate packet at the currently fixed snaplen.

It set snaplen to MTU length if the MTU can be retrieved. If not, it
does not set the snaplen which results in using a 65535 snaplen.

libpcap is trying to use mmaped capture and setup the ring by using buffer_size
as the total memory. It also use "rounded" snaplen as frame size. So if we set
snaplen to MTU when available we are optimal regarding the building of the ring.
