Victor Julien	bb2e9af40f	pcap-file: clean up decode thread local storage ... Clean up the thread local data the decode portion of pcap-file use. Bug #978.	11 years ago
Victor Julien	f7b1aefaf4	Bug 1107: decoders: bail out on pseudo packets ... Flow-timeout code injects pseudo packets into the decoders, leading to various issues. For a full explanation, see: https://redmine.openinfosecfoundation.org/issues/1107 This patch works around the issues with a hack. It adds a check to each of the decoder entry points to bail out as soon as a pseudo packet from the flow timeout is encountered. Ticket #1107.	12 years ago
Victor Julien	5f307acace	Pass ThreadVars ptr to various thread init funcs ... To be able to register counters from AppLayerGetCtxThread, the ThreadVars pointer needs to be available in it and thus in it's callers: - AppLayerGetCtxThread - DecodeThreadVarsAlloc - StreamTcpReassembleInitThreadCtx	12 years ago
Eric Leblond	afbb2eb32b	capture: display exit stats at default verbosity ... This patch updates capture modes not using LiveDecice counters to display per-thread exit statistics with default verbosity.	12 years ago
Eric Leblond	1bdc39fe9b	cmdline: add -k to specify checksum validation ... This patch adds a '-k' option to suricata to be able to specify the checksum validation to use. If '-k all' is used, checksum validation is forced. If '-k none' is used, no checksum validation is made. Message output in case of detection of a pcap file with a probable cheksum issue has been updated to indicate that '-k' is a solution.	12 years ago
Eric Leblond	8b5be26f49	pcap-file: add checksum-checks configuration variable ... This patch adds support for checksum-checks in the pcap-file running mode. This is the same functionnality as the one already existing for live interface. It can be setup in the YAML: pcap-file: checksum-checks: auto A message is displayed for small pcap to warn that invalid checksum rate is big on the pcap file and that checksum-check could be set to no.	12 years ago
Eric Leblond	3088b6ac34	Add invalid pkt counter. ... This patch adds and increments a invalid packet counter. It does this by introducing PacketDecodeFinalize function This function is incrementing the invalid counter and is also signalling the packet to CUDA.	12 years ago
Eric Leblond	d4b7ecfbe3	decode: update API to return error ... In some cases, the decoding is not possible and some really invalid packet can be created. This is in particular the case of tunnel. In that case, it is more interesting to forget about the tunneled packet and only consider the original packet. DecodeTunnel function is maked as warn_unused_result because it is meaningful for the decoder to know if the underlying data were not correct. And in this case, only focus detection on the content.	12 years ago

Eric Leblond	5b067e1abb	pcap-file: treat the case of unsupported pcap link ... In unix socket mode, Suricata was stopping processing pcap files when a pcap file with an unsupported datalink was treated. This patch updates error handling to allow Suricata to treat other pcap files.	13 years ago
Eric Leblond	6b81430bcb	pcap-file: don't kill engine in unix socket mode ... This patch updates the cleaning code to avoid to exit from suricata in unix socket mode when a invalid pcap is given.	13 years ago
Eric Leblond	f8921d8a28	unix-socket: introduce API to add commands and tasks ... This patch transforms the unix socket into a flexible system to add commands (triggered by user) and taks (run periodically). It introduces two functions UnixManagerRegisterCommand and UnixManagerRegisterBackroundTask to registed commands and tasks. Other part of Suricata can then declare a new command via a simple call of the function. In the case of a command the caller is responsible of building the answer message using Jansson API. The sending of the message is made by unix manager code.	13 years ago
Eric Leblond	20a8b9dbe5	unix-manager: add unix command socket and associated script ... This patch introduces a unix command socket. JSON formatted messages can be exchanged between suricata and a program connecting to a dedicated socket. The protocol is the following: * Client connects to the socket * It sends a version message: { "version": "$VERSION_ID" } * Server answers with { "return": "OK|NOK" } If server returns OK, the client is now allowed to send command. The format of command is the following: { "command": "pcap-file", "arguments": { "filename": "smtp-clean.pcap", "output-dir": "/tmp/out" } } The server will try to execute the "command" specified with the (optional) provided "arguments". The answer by server is the following: { "return": "OK|NOK", "message": JSON_OBJECT or information string } A simple script is provided and is available under scripts/suricatasc. It is not intended to be enterprise-grade tool but it is more a proof of concept/example code. The first command line argument of suricatasc is used to specify the socket to connect to. Configuration of the feature is made in the YAML under the 'unix-command' section: unix-command: enabled: yes filename: custom.socket The path specified in 'filename' is not absolute and is relative to the state directory. A new running mode called 'unix-socket' is also added. When starting in this mode, only a unix socket manager is started. When it receives a 'pcap-file' command, the manager start a 'pcap-file' running mode which does not really leave at the end of file but simply exit. The manager is then able to start a new running mode with a new file. To start this mode, Suricata must be started with the --unix-socket option which has an optional argument which fix the file name of the socket. The path is not absolute and is relative to the state directory. THe 'pcap-file' command adds a file to the list of files to treat. For each pcap file, a pcap file running mode is started and the output directory is changed to what specified in the command. The running mode specified in the 'runmode' YAML setting is used to select which running mode must be use for the pcap file treatment. This requires modification in suricata.c file where initialisation code is now conditional to the fact 'unix-socket' mode is not used. Two other commands exists to get info on the remaining tasks: * pcap-file-number: return the number of files in the waiting queue * pcap-file-list: return the list of waiting files 'pcap-file-list' returns a structured object as message. The structure is the following: { 'count': 2, 'files': ['file1.pcap', 'file2.pcap'] }	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.
