Jason Ish	ea020e2be6	Do not trim the FCS, pcaps converted to ERF will have have an FCS.	13 years ago
Anoop Saldanha	34581ce902	rx TMs shouldn't return TM_ECODE_FAILED if engine is in shutdown mode + minor cleanup	13 years ago
Anoop Saldanha	bc6cf43840	#482 - use decode_flag for all decode TMs. Use the flag as a way to retrieve decode TMs from ThreadVars	13 years ago
Anoop Saldanha	cd4705e699	flag recieve acq tms that previously missed the receive_tm flag	14 years ago
Jason Ish	1f801d316c	Apply changes recommended by Stephen Donnely of Endace: - Skip pad records. - Don't log error on EGAIN, just try again. - Skip over extension headers. - Check we have the full packet (skip partial packets) - Remove obsolete rlen check. Also remove max_pending_packets to process more packets per iteration.	14 years ago
Jason Ish	105173939b	Implement single, autofp and workers run modes for DAG interfaces. Includes multiple interface support. ... Remove auto mode due to bad performance.	14 years ago
Anoop Saldanha	3f1c4efceb	Add new flags var to tm module. TMs can now set flags to identify special properties. Also use these to identify receive TMs	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.

Eric Leblond	89558ab9a4	RFC: modify error treatment in PacketCopyData ... Hello Victor This patch modifies error treatment following our discussion on IRC. It tries to follow the error treatment guideline I've been able to read in the different files. I will merge this patch in the original commit if the error treatment seems ok for you. BR, Eric	15 years ago
Eric Leblond	dd038c1906	Modify files to avoid direct pckt payload access ... This patch implements the needed modification of payload access in a Packet structure to support the abstraction introduced by the extended data system.	15 years ago
Victor Julien	4cacb1e970	Disable adding to unregistered mbit/s counter.	15 years ago
Jason MacLulich	ae095e585b	o Changed SCMalloc to DecodeThreadVarsAlloc in Decode thread initialization. (Ish) o Changed htons to noths. (Ish) o Added support for handling DAG cards running DSM modules and other non-standard ETH ERF types. o Added support for allowing gracefull restarts of the fetch thread if it fails to read an ERF properly.	15 years ago
Victor Julien	6519a86ec7	Move packet pool to ringbuffer, update packet pool api and ringbuffer api. Remove memset usage from PACKET_RECYCLE, add proper cleanup macros.	15 years ago
Victor Julien	dce323b1f4	Fix SCondWait -> SCCondWait typo.	15 years ago
Jason MacLulich	835630efbd	Add initial support for reading packets from a DAG card, we only support reading from a single stream at this time. ... Use the --dag <dagname> cmd line option to specify from which DAG card to read pkts from. Issue at the moment with pkts being ejected during shutdown -- at the moment we ignore any packets that are not of link type Ethernet.	15 years ago
