Victor Julien	1d18155a16	XFF: use per alert tx id ... Use the tx id stored for each alert to find the correct XFF address to add to the extra-data field. In overwrite mode we still only grab the first available XFF addr, as this address is set in the header preceeding the individual alerts. Issue #904.	13 years ago
Victor Julien	c8b71938ff	Add a fallback memrchr implementation for those platforms that dont support it. Bug #963.	13 years ago

Duarte Silva	7dbb305255	Adds X-Forwarded-For support to the Unified2 output format ... - Added the Unified2 file format related constants - Added IPv6 support - Two modes of operation with a fall-back to "extra-data" mode if "overwrite" mode is not applicable - Changed the configuration loading code to handle the new configuration structure - When creating the packet that fakes the one that generated the alert the flow direction wasn't taken into account in overwrite mode - Fixed BUG_ON condition	13 years ago
Eric Leblond	c5bd04f102	unittest: recycle packet before exit ... To avoid an issue with flow validation, we need to recycle the packet before cleaning the flow.	13 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)	13 years ago

Victor Julien	72443a0d62	unified2: append open instead of trucate open so that in case we rotate within a second we don't overwrite files. Instead we violate the limit.	14 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	14 years ago

Anoop Saldanha	7c9d1b80fd	Update size parsing API with new calls for returing u8, u16, u32 and u64 values. Make updates in the codebase to use these new calls	15 years ago
Anoop Saldanha	e0c13434ef	bug 333 - support new Size Parsing API. Update various conf params inside the engine to use this API to parse sizes in the format xxx <-just the no represents bytes, xxxkb <- kilobytes, xxxmb <- megabytes, xxxgb <- gigabytes, where xxx is a \d+	15 years ago
Victor Julien	f47f601f09	Fix unified2 setting the wrong eth_type.	15 years ago
Eric Leblond	9422a36851	unified2: avoid to log RAW packet ... If the packet datalink is ethernet, we add a fake ethernet header to stream logging to avoid that barnyard2 create different files.	15 years ago
Eric Leblond	fc56abfcd0	unified2: log an ethernet header for stream alert. ... If packet is a of type ethernet, we log the alert reconstructed payload as an ethernet packet and not a raw packet. This will avoid to confuse barnyard2 pcap output.	15 years ago
Victor Julien	39edb23ac4	Support stream.inline mode in unified2 tcp segments logging.	15 years ago
Victor Julien	2e2e80b812	Add packet alert flag to indicate a match happened (partly) in the app layer state. Make unified2 use this flag.	15 years ago

Eric Leblond	7fd1e9cacc	unified2: synchronize IPv4 and IPv6 code ... IPv6 code was missing some points.	15 years ago
Eric Leblond	839b0d9bfe	unified2: switch to event->packet->packet mode. ... Attach multiple packets to an event instead of using one event data per packet. This is currrently unsupported by reporting frontend but at least we don't have multiple alerts.	15 years ago
Eric Leblond	316f2d7289	unified2: segment callback log raw packet. ... As we don't have any trustable information about the ethernet header, we can simply log RAW packet to avoid to confuse the analyst.	15 years ago
Eric Leblond	a03a402b83	unified2: set datalink to correct value. ... The value of datalink could have been modified if the logging of segment was attempted. This patch restore it to a correct value.	15 years ago
Eric Leblond	50ddd2df43	Restore old barnyard2 support. ... Some old version of barnyard2 were needing a workaround in the packet header building. THis patch introduces a enable-old-barnyard2 configure flag which can be used to restore this behaviour.	15 years ago

Eric Leblond	79c329f81b	alert-unified2: logging of stream segments. ... This patch adds the logging of stream segments. Among other modifications, it uses a wrapper to fwrite to permit to update file statistics in an automated manner. Some memcpy have also been avoided by using pointer to the data.	15 years ago
William Metcalf	3b3f5816bf	You spin me right round baby, right round like a rotating packet capture right round. Oh, also log file size counters are now uint64_t	15 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.
