Anoop Saldanha	0d7159b525	App layer protocol detection updated and improved. We now use ... confirmation from both directions and set events if there's a mismatch between the 2 directions. FPs from corrupt flows have disappeared with this.	12 years ago
Anoop Saldanha	c044541b1c	Provide convenience macros for setting flow flags on protocol matching by ... PM and PP phase. Replace the areas of the code that would otherwise rely on setting/reading these flags with these macros. Other minor tweaks to some api calls.	12 years ago
Anoop Saldanha	00f546e739	update pmp to return whole set of matches, rather than a single match.	12 years ago
Anoop Saldanha	d9686fae57	Now supports accepting port addresses as strings, like the ones accepted in our rules. As a consequence we now accept port range, and other such combination. Support PP for ports based on ipproto as well.	12 years ago
Eric Leblond	3dbf6c6fee	solaris: fix compilation failure ... This patch fixes a compilation failure on Solaris. Compiler does not support when a function returning void is used in return of an other function returning void.	12 years ago
Eric Leblond	cd3e32ce19	unittests: some functions needs a flow lock. ... In debug validation mode, it is required to call application layer parsing and other functions with a lock on flow. This patch updates the code to do so.	12 years ago
Anoop Saldanha	3c2ddf04c1	Update mpm init ctx to not accept the final cuda_rc_module argument. ... It was a part of our older architecture and is no longer used.	12 years ago
Anoop Saldanha	b787da5643	Remove all cuda related code in the engine except for the cuda api wrappers	12 years ago
Ken Steele	394f99e32c	Use PacketGetfromAlloc() for packet allocation instead of SCMalloc. ... Only changed in one file for testing.	12 years ago
Anoop Saldanha	34a9c047fc	updated to fix unix shutdown sequence ... Should fix crashes occuring from unix mode shutdown/cleanup phase.	13 years ago
Last G	8ae11f73b2	Added parentheses to fix Eclipse static code analysis ... Fixed bug in action priority (REJECT_DST had lowest prio)	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

Anoop Saldanha	01a35bb604	introduce app layer local storage api support	14 years ago
Victor Julien	262a7300d7	flow: shrink Flow datatype ... Introduce a separate FlowAddress structure for holding the ipv4 or ipv6 address that doesn't have the family in it like the Address structure. Instead, the family is stored in the flow as a flag: FLOW_IPV4 and FLOW_IPV6. Add macro's to check the family, copy the address, etc. Update many unittests to reflect these changes. Introduce unittest helper functions for creating and initializing a flow and freeing it again. On 64 bit this shrinks the flow with 8 bytes.	14 years ago
Victor Julien	06904c9024	App Layer cleanup ... Removal of per flow 'aldata' array. It contained a ptr for each ALPROTO. Instead now we have 2 ptrs in the flow: alparser and alstate. Various cleanups and dead code removal from the app layer API. Should safe 100+ bytes memory per flow on 64 bit. Updated lots of unittests to reflect these changes.	14 years ago
Anoop Saldanha	ed3b44b3b5	fix parsing content keywords. We are more strict now. All content keywords need to be enclosed in double quotes. Better validation for sid, priority and rev keywords	14 years ago

Anoop Saldanha	d68f182ebd	introduce SCPerfSyncCounters/SCPerfSyncCounters macro to synchronize counters	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.
