Eric Leblond	7425bf5ca6	Rename some decode event structure and macro. This patch renames DECODER_SET_EVENT, DECODER_ISSET_EVENT and some other structures to ENGINE equivalent to take into account the fact the event list is now related to all engines and not only to decoder.	14 years ago
Eric Leblond	5bbd8fe910	Add reference to events sig files in suricata YAML config.	14 years ago
Eric Leblond	552c6731b2	Add signature file for stream events. This patch adds a rules/stream-events.rules file which contains alert related to all stream events.	14 years ago
Eric Leblond	de65b11c42	decode signature optimisation requires different treatment Decode signature are using the fact that no proto is set on packet to increase the matching speed. This is not the case of stream and other engine events. Thus a difference needs to be made.	14 years ago
Eric Leblond	3f153fb0da	Add 'stream-event' keyword. This patch adds an alias to the 'engine-event' keyword. It is now possible to access to the stream events via the 'stream-event' keyword. A simple transformation is done: stream-event:reassembly_segment_before_base_seq is a shortcut for: engine-event:stream.reassembly_segment_before_base_seq	14 years ago
Eric Leblond	eb0d4e4d8b	Add stream events support to 'engine-event' keyword This patch adds the list of stream events (with associated keywords) to the list of events that can be treated by 'engine-event'.	14 years ago
Eric Leblond	e3a6d8955e	Introduce engine-event keyword This patch renames the 'decode-event' keyword to 'engine-event' and keep it for backword compatibility of rulesets. All DecodeEvent references in the code are replaced by EngineEvent version.	14 years ago
Eric Leblond	2ac8755382	Rename detect-decode-event to detect-engine-event This patch does a simple renaming of detect-decode-event file to the more global detect-engine-event name.	14 years ago
Victor Julien	21f387d2c7	profiling: fix stream ticks miscalculation on stream end pseudo packets.	14 years ago
Eric Leblond	ff6365dd33	af-packet: switch to pcktacqloop API. This patch gets rid of the old API and brings some optimisation by reordering structure and optimisinf an error test.	14 years ago
Eric Leblond	834c91eece	af-packet: add AFP to per packet performance system.	14 years ago
Eric Leblond	fb4be6199f	af-packet: change option name This patch changes the option name. af-packet long option is now used instead of -a to mimic pfring behaviour. This patch improves the standard parsing of the command line. Running suricata -c suricata.yaml --af-packet will start a suricata running in AF_PACKET mode listening on all interfaces defined in the suricata.yaml configuration file. The traditionnal syntax: suricata -c suricata.yaml --af-packet=ppp0 will start a suricata listening on ppp0 only.	14 years ago
Eric Leblond	e253da092c	device: Add function to build interface list from config This patch adds a new function which build the list of interfaces to use by parsing the configuration file. This is using the new format and thus only af-packet can benefit of this feature.	14 years ago
Eric Leblond	df7dbe36b6	af-packet: Add option to disable promiscuous mode This patch adds an option to suricata.yaml to be able to disable the switch of the interface into promiscuous mode.	14 years ago
Eric Leblond	fbca1a4e6b	af-packet: multi interface support This patch adds multi interface support to AF_PACKET. A structure is used at thread creation to give all needed information to the input module. Parsing of the options is done in runmode preparation through a dedicated function which return the configuration in a structure usable by thread creation.	14 years ago
Eric Leblond	18c6503a08	af-packet: change configuration format for multi interface	14 years ago
Eric Leblond	dc667af1a1	conf: Introduce new function to input configuration. The input modules are needing a per interface configuration. This implies some new operations to be able to parse easily te configuration. The syntax of the configuration file is for example: af-packet: - interface: eth0 threads: 2 - interface: eth1 threads: 3 We need a way to express get a configuration variable for interface[eth0]. This is by using ConfNodeLookupKeyValue() to get the matching node. And after that value can be fetch by using ConfGetChildValue*() functions.	14 years ago
Eric Leblond	e80b30c082	af-packet: finalize code This patch handles the end of AF_PACKET socket support work. It provides conditional compilation, autofp and single runmode. It also adds a 'defrag' option which is used to activate defrag support in kernel to avoid rx_hash computation in flow mode to fail due to fragmentation. This patch contains some fixes by Anoop Saldanha, and incorporate change following review by Anoop Saldanha and Victor Julien. AF_PACKET support is only build if the --enable-af-packet flag is given to the configure command line. Detection of code availability is also done: a check of the existence of AF_PACKET in standard header is done. It seems this variable is Linux specific and it should be enough to avoid compilation of AF_PACKET support on other OSes. Compilation does not depend on up-to-date headers on the system. If none are present, wemake our own declaration of FANOUT variables. This will permit compilation of the feature for system where only the kernel has been updated to a version superior to 3.1.	14 years ago
Eric Leblond	871b21892a	factorize pcap live device function They are not specific to pcap and could thus be used in other module.	14 years ago
Eric Leblond	c45d898572	af-packet: basic support for AF_PACKET socket This patch provides basic support for AF_PACKET socket. It is completed by a subsequent patches prodiding extended features and bugfixes.	14 years ago

Victor Julien	fca541f40e	Add per app layer parser profiling Per packet per app layer parser profiling. Example summary output: Per App layer parser stats: App Layer IP ver Proto cnt min max avg -------------------- ------ ----- ------ ------ ---------- ------- ALPROTO_HTTP IPv4 6 163394 126 38560320 42814 ALPROTO_FTP IPv4 6 644 117 26100 2566 ALPROTO_TLS IPv4 6 670 117 7137 799 ALPROTO_SMB IPv4 6 114794 126 225270 957 ALPROTO_DCERPC IPv4 6 5207 126 25596 1266 Also added to the csv out. In the csv out there is a new column "stream (no app)" that removes the app layer parsers from the stream tracking. So raw stream engine performance becomes visible.	14 years ago
Victor Julien	0cc9f39200	Move TlsConfig structure out of app-layer-protos.h and rename it to SslConfig.	14 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.
