Mats Klepsland	8c3f1aa7a5	tlslog: don't log as "resumed" without ServerHello ... Don't log a session as "resumed" if a ServerHello record has not been seen. This makes sure that incomplete TLS sessions where the ClientHello contains a session ticket, is not logged as a session resumption.	7 years ago

Jason Ish	c3f1a35e28	rust: app-layer template parser and logger ... The protocol is a simple request/reply based protocol that can be hand driven with netcat. Request -> 12:Hello World! Response -> 3:Byte Its of the format <length>:<message> where length is the length of the message, not including the length or the delimiter.	7 years ago

Jason Ish	9da00bebf0	scripts/setup: remove 'ed' based setup scripts ... Removes: - setup-app-layer.sh - setup-app-layer-logger.sh These have been replaced by setup-app-layer.py.	7 years ago
Jason Ish	e232fcc415	setup-app-layer: rewrite script in Python ... The idea being that it is easier to read and maintain than wrapping ed commands. This script also merges the parser and logger setup into a single script, but still allows just the parser, or just the logger to be generated with flags, --logger and --parser.	7 years ago

Jacob Masen-Smith	b1b45a54c5	detect/analyzer: disable automatic json output ... EngineAnalysisRules2 was in a strange location where it did not respect the --engine-analysis flag. It has been moved to the same call location as EngineAnalysisRules.	7 years ago

Victor Julien	e02b74dee7	http: implement min size stream logic ... Update HTTP parser to set the min inspect depth per transaction. This allows for signatures to have their fast_pattern in the HTTP body, while still being able to inspect the raw stream reliably with it. The inspect depth is set per transaction as it: - depends on the per personality config for min inspect size - is set to the size of the actual body if it is smaller After the initial inspection is done, it is set to 0 which disables the feature for the rest of the transaction. This removes the rescanning flush logic in commit 7e004f52c6 and provides an alternative fix for bug #2522. The old approach caused too much rescanning of HTTP body data leading to a performance degradation. Bug #2522	7 years ago
Victor Julien	7186ce7b99	stream: introduce min inspect depth logic ... Some rules need to inspect both raw stream data and higher level buffers together. When this higher level buffer is a streaming buffer itself, the risk of mismatch exists. This patch allows an app-layer parser to set a 'min inspect depth'. The value is used by the stream engine to keep at least this depth worth of data, so that the detection engine can request all of it for inspection. For rules that have the SIG_FLAG_FLUSH flag set, data is inspected not from offset raw_progress, but from raw_progress minus min_inspect_depth. At this time this is only used for sigs that have their fast_pattern in a HTTP body and have raw stream match as well.	7 years ago

Jason Ish	aa98678662	defrag: remove fragments that have complete overlap ... Instead of just marking fragments that have been completely overlapped and won't be part of the assembled packet, remove them from the fragment tree when detected.	7 years ago
Jason Ish	fe6e96a8c1	defrag: use rb tree to store fragments	7 years ago
Victor Julien	023a2fe9ab	unittests: fix format-truncation warning	7 years ago
Victor Julien	269313a53e	stream/segments: change packing to reduce size ... Change the way fields are ordered to reduce TcpSegment structure with 8 bytes.	7 years ago
Victor Julien	b6b9b56e45	stream/segments: keep track of tree right edge ... Use this in places where we need to use the outer right edge of our sequence space. This way we can avoid walking the tree to find this, which is a potentially expensive operation.	7 years ago
Victor Julien	ea771c69af	streaming/sbb: convert RB_MIN to 'head'	7 years ago
Victor Julien	bbf1f78ffe	streaming: keep track of tree 'head'	7 years ago
Victor Julien	450500e667	streaming: use rbtree for stream blocks ... Switch StreamBufferBlocks implementation to use RBTREE instead of a list. This makes inserts/removals and lookups a lot cheaper if the number of data gaps is large. Use separate compare functions for inserts and regular lookups. Inserts care about the offset, while lookups care about the blocks right edge as well.	7 years ago
Victor Julien	9bda558c59	stream/sack: optimize SACK size handling ... Optimize by keeping count during insert/remove instead of walking the tree per check.	7 years ago
Victor Julien	7ec7d234cc	stream/sack: turn SACK record list into rbtree ... Convert to rbtree from linked list. These ranges, of which there can be multiple per packet, are fully controlled by an attacked. The attacker could craft a stream of packet in such a way that the list would grow very large. This would make inserts/removals very expensive, as well as the list walk that is done and size calculation and pruning operations. The RBTREE makes inserts/removals much cheaper, at a slight overhead for 'normal' operations and slightly higher per record memory use.	7 years ago
Victor Julien	51ce03e76a	stream/segments: speed up inserts ... Don't try to do a 'fast path' by checking RB_MAX. RB_MAX walks the tree which means it can be quite expensive. This cost would be paid for virtually every data segment. The actual insert that follows would walk the tree again. Instead, simply insert it. There is a slight cost of the unnecessary overlap check, but this is much less than the tree walk in a full tree.	7 years ago
Victor Julien	f4ff33969e	stream/segments: remove RB_MIN/RB_MAX	7 years ago
Victor Julien	00e65e3cfa	stream/segments: optimize overlap tree operations ... Now that with the RBTREE we have a properly sorted Segment tree, where with exact SEQ matches the tree is sorted by payload_len smallest to largest, we can avoid walking backwards when checking for overlaps. Our direct RB_PREV either overlaps or not and that is a reliable verdict for the rest of the tree.	7 years ago
Victor Julien	26b5e1ed13	stream/segments: turn linked list into rbtree ... To improve worst case performance turn the segments list into a rbtree. This greatly improves inserts, lookups and removals if the number of segments gets very large. The tree is sorted by the segment sequence number as its primary key. If 2 segments have the same seq, the payload_len (segment length) is used. Then the larger segment will be places after the smaller segment. Exact matches are not added to the tree.	7 years ago
