Ken Steele	28ccea51d3	Add error checking for pthread_setspecific() and pthread_key_create().	11 years ago
Ken Steele	a38d5a0135	Implement thread specific data option when __thread is not available.	11 years ago
Ken Steele	3c6e01f653	Replace ringbuffer in Packet Pool with a stack for better cache locality Using a stack for free Packet storage causes recently freed Packets to be reused quickly, while there is more likelihood of the data still being in cache. The new structure has a per-thread private stack for allocating Packets which does not need any locking. Since Packets can be freed by any thread, there is a second stack (return stack) for freeing packets by other threads. The return stack is protected by a mutex. Packets are moved from the return stack to the private stack when the private stack is empty. Returning packets back to their "home" stack keeps the stacks from getting out of balance. The PacketPoolInit() function is now called by each thread that will be allocating packets. Each thread allocates max_pending_packets, which is a change from before, where that was the total number of packets across all threads.	11 years ago
Victor Julien	ab503873ca	erf-file: clean up decode thread local storage Clean up the thread local data the decode portion of ERF users. Bug #978	12 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	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
Victor Julien	698ff4e4aa	Counters: remove all unused parts of the API	12 years ago
Last G	8bb9c3af35	Added return value to non-void function with "forever"-loop to fit Eclipse static code analysis	13 years ago
Anoop Saldanha	b33986c887	Add a packet src for every packet generated inside suricata.	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
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
Jason Ish	90548837e3	Update the ERF file runmodes to support autofp and single.	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.
