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).

Victor Julien 53977fded6 Small compilation fixes when debugging is disabled. 16 years ago
Victor Julien 6a53ab9c5a Stream engine memory handling update 
The stream engine memory handling needed updating as it didn't scale. Changes:

- pools can now be initialized to size 0, meaning unlimited
- 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.

Steve Grubb f853da7940 Get make distcheck working 
Hello,

Below is a patch that gets "make distcheck" working. Its against the
current code in git. The project version was set to 0.1 in configure,
I changed that to 0.8.1 just so its actually relevant. You might want
to set that to something else.

After checking this patch, I find that there are several source code
files in src/ that are not getting compiled:

-app-layer-detect.c
-app-layer-detect.h
-app-layer-http.c
-reputation.h

Are these new or abandoned? Anyways...here's the patch.

  the end of the pkt buffer.

Steve Grubb c95cd2e80a memory leak cleanups in misc places 
Hello,

This is all the rest of the memory leaks I found.

*In src/source-pcap-file.c at line 152, ptv is not being freed.
*In src/util-unittest-helper.c at line 152, p was not being freed.
*In src/log-httplog.c at line 195, aft was not being freed
*In src/counters.c at line 51, log_filename was not being freed. At line 1188
pctx is being tested to see if its NULL. However, at 1173 it exits the
function if it were NULL. This test is not needed and should be deleted.
*In src/defrag.c at line 351, tracker was not being freed. At line 390, dc is
being checked for NULL but this was already done at line 384. Probably what
was meant was checking the value of dc->frag_table which was just assigned.

The patch below makes the above described changes.

Steve Grubb 60ad9d29c5 Memory leak cleanup in detectors 
Hello,

I ran the code through an analysis program and found several leaks that
should be cleaned up.

*In src/detect-engine-address-ipv4.c at line 472, the test for ag == NULL
will never be true since that is the loop entry test.
*In src/detect-engine-port.c at line 1133, the test for p == NULL will
never be true since that is the loop entry test.
*In src/detect-engine-mpm.c at line 263 is a return without freeing
fast_pattern
*In src/detect-ack.c at line 80 and 85, data catches the return from malloc.
One of them should be deleted.
*In src/detect-seq.c at line 81 and 86, data catches the return from malloc.
One of them should be deleted.
*In src/detect-content.c at line 749, many of the paths that lead to the error
exit still has temp pointing to allocated memory. To clean this up, temp
should be set to NULL if not immediately assigning and new value.
*In src/detect-uricontent.c at line 319, both cd and str needto be freed. At
lines 344, str needs to be freed. And at line 347 str and temp need to be
freed.
*In src/detect-flowbits.c at line 231 and 235, str was not being freed. cd was
not being freed at line 235.
*In src/detect-flowvar.c at line 127, str was not being freed. At line 194, cd
and str were not being freed.
*In src/detect-flowint.c at line 277, sfd was not being freed. At line 315, str
was not being freed.
*In src/detect-pktvar.c at line 121, str was not being freed. At line 188, str
and cd was not being freed.
*In src/detect-pcre.c at line 389, there is an extra free of "re" that should
be deleted.
*In src/detect-depth.c at line 42 & 48, str has not been freed.
*In src/detect-distance.c at line 49 and 55, str has not been freed
*In src/detect-offset.c at line 45, str has not been freed.

Eric Leblond 51be576a30 nfq: modify queue length computation logic 
This patch modifies  max queue length computation logic. The max queue
length was set to MAX_PENDING which is the total number of packet
processed simultaneously in suricata.

This value is correct but this will not permit to take all burst
effects into account (read sudden quantity of packet that arrives
faster than suricata is enable to parse). Furthermore there is a
delaying system when suricata gets overloaded which make necessary
to have packet storable into kernel for some time.

To improve this situation the patch increases the maximum queue
length to NFQ_BURST_FACTOR (4) time the MAX_PENDING packet and
it also increase the nfnetlink buffer size to be able to store
all packets waiting for suricata in the netlink receive buffer.
