Justin Viiret	c9d0d6f698	mpm: add "auto" default for mpm-algo ... Setting mpm-algo to "auto" will use "hs" if Suricata was built against Hyperscan, and "ac" otherwise (or "ac-tile" on Tilera platforms).	9 years ago
Mats Klepsland	a13df67864	detect: add (mpm) keyword for tls_sni ... Match on server name indication (SNI) extension in TLS using tls_sni keyword, e.g: alert tls any any -> any any (msg:"SNI test"; tls_sni; content:"example.com"; sid:12345;)	9 years ago

Victor Julien	87f3adbe4c	detect/mpm: unify packet/stream mpm_ctx pointers ... SGH's for tcp and udp are now always only per proto and per direction. This means we can simply reuse the packet and stream mpm pointers. The SGH's for the other protocols already used a directionless catch all mpm pointer.	9 years ago
Victor Julien	6bb2b001a3	mpm: cleanup: move mpm funcs into buffer specific files	9 years ago
Victor Julien	c880b79f45	detect: shrink sgh ... Turn list of mpm_ctx pointers into a union so that we don't waste space. The sgh's for tcp and udp are in one direction only, so the ts and tc ones are now in the union.	9 years ago
Victor Julien	c804102a9a	detect: move app_mpms array to init data	9 years ago
Victor Julien	9b3d4f7e24	mpm: unify & localize mpm pattern (id) handling ... So far, the patterns as passed to the mpm's would use global id's that were shared among all buffers, directions. This would lead to a fairly large pattern id space. As the mpm algo's use the pattern id's to prevent duplicate matching through a pattern id based bitarray, shrinking this space will optimize performance. This patch implements this. It sets a flag before adding the pattern to the mpm ctx, instructing the mpm to ignore the provided pid and handle pids management itself. This leads to a shrinking of the bitarray size. This is made possible by the previous work that removes the pid logic from the code. Next to this, this patch moves the pattern setup stage to common util functions. This avoids code duplication. Update ac, ac-bs and ac-ks to use this.	9 years ago
Victor Julien	ba9d43cce5	mpm: improve negated mpm ... The idea is: if mpm is negated, it's both on mpm and nonmpm sid lists and we can kick it out in that case during the merge sort. It only works for patterns that are 'independent'. This means that the rule doesn't need to only match if the negated mpm pattern is limited to the first 10 bytes for example. Or more generally, an negated mpm pattern that has depth, offset, distance or within settings can't be handled this way. These patterns are not added to the mpm at all, but just to to non-mpm list. This makes sense as they will *always* need manual inspection. Similarly, a pattern that is 'chopped' always needs validation. This is because in this case we only inspect a part of the final pattern.	9 years ago
