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

Victor Julien	11f213fb80	stream/tcp: be more liberal in last_ack ... Don't set even if seq is before next_seq, as this could still be a valid packet that was sent before the state was reached.	7 years ago

Mats Klepsland	4d38d0844b	doc: add documentation for Lua function 'TlsGetVersion'	7 years ago
Mats Klepsland	04e78ace0a	lua: add function 'TlsGetVersion' ... Add another function to get TLS version, since 'TlsGetCertInfo' only works when a TLS session contains a clear text certificate, which is not the case in TLSv1.3 or when a session is resumed.	7 years ago

Mats Klepsland	df9853b75c	detect-tls-version: add support for 'raw' matching ... Add support for matching a 'raw' TLS version using a hex string, e.g: tls.version:0x7f12; The above example matches TLSv1.3 draft 16.	7 years ago

Mats Klepsland	f22bd5a75b	app-layer-ssl: decode server hello record ... Decoding server hello is needed to do a better implementation of session resumption.	7 years ago

Victor Julien	88277d0402	detect: fix file_data detect issue with alert ip ... Fix mpm progress being updated by irrelevant engines. Esp in the case of file_data engines, signature can contain multiple versions of the same engine, registered for different 'progress' values. This would lead to signatures being considered 'can't match' even in cases where they clearly could still match. Only consider those progress values that apply to the protocol in use.	7 years ago
