Eric Leblond	3f107fa130	decode: Packet action start with PACKET ... Rename all Packet action macro to have them prefixed by PACKET.	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: @@ Packet *p; expression E; @@ - p->action & E + TEST_PACKET_ACTION(p, E)	12 years ago
Victor Julien	782aa5adae	prelude: only call stream callback for TCP	13 years ago
Eric Leblond	06751ecd75	prelude: don't build string objet for NULL string ... prelude_string_set_ref don't like when it is called with a NULL parameter. This patch adds check for NULL value. This is formally good as there is no use of a NULL description.	13 years ago
Eric Leblond	e176be6fcc	Use unlikely for error treatment. ... When handling error case on SCMallog, SCCalloc or SCStrdup we are in an unlikely case. This patch adds the unlikely() expression to indicate this to gcc. This patch has been obtained via coccinelle. The transformation is the following: @istested@ identifier x; statement S1; identifier func =~ "(SCMalloc|SCStrdup|SCCalloc)"; @@ x = func(...) ... when != x - if (x == NULL) S1 + if (unlikely(x == NULL)) S1	13 years ago

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 ------ ----- ------ ------ ---------- ------- IPv4 6 19436 11448 5404365 32993 IPv4 256 4 11511 49968 30575 Per Thread module stats: Thread Module IP ver Proto cnt min max avg ------------------------ ------ ----- ------ ------ ---------- ------- TMM_DECODEPCAPFILE IPv4 6 19434 1242 47889 1770 TMM_DETECT IPv4 6 19436 1107 137241 1504 TMM_ALERTFASTLOG IPv4 6 19436 90 1323 155 TMM_ALERTUNIFIED2ALERT IPv4 6 19436 108 1359 138 TMM_ALERTDEBUGLOG IPv4 6 19436 90 1134 154 TMM_LOGHTTPLOG IPv4 6 19436 414 5392089 7944 TMM_STREAMTCP IPv4 6 19434 828 1299159 19438 The proto 256 is a counter for handling of pseudo/tunnel packets.

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). Signed-off-by: Pierre Chifflier <chifflier@edenwall.com>	16 years ago
