Victor Julien	13e60c0040	stream: detect keep-alive packets so we don't consider those invalid	12 years ago
Victor Julien	9094eb4783	stream: ignore ack value if ack flag is not set. Add stream.pkt_broken_ack event for when ack value is not 0 and ack flag not set.	12 years ago
Victor Julien	a5d9442c2d	stream: handle retransmission of lost data packet on TIME_WAIT state	12 years ago

Victor Julien	6f76ac176d	stream: add option to match on overlapping data ... Set event on overlapping data segments that have different data. Add stream-events option stream-event:reassembly_overlap_different_data and add an example rule. Issue 603.	12 years ago
Victor Julien	0b68da0b31	libhtp: don't use internal iterator ... It violates thread safety. #601. Suricata assures thread safety on the flow level for HTTP tracking. Part of the flow is (in case of HTTP) libhtp's htp_connp_t state. At startup the libhtp glue layer, app-layer-htp initializes as many htp_cfg_t instances as there are libhtp server configurations in the yaml. At HTTP session start, we look up the proper htp_cfg_t based on the server ip and pass it to htp_connp_create. A ptr to the relevant htp_cfg_t is part of the htp_connp_t. The htp_cfg_t contains "hooks". The are registered based on yaml config at init time. The hooks have lists of type list_t. The list is run with a built in iterator. The iterator is reset at the start of each "hook_run_all". Since multiple flows share the same htp_cfg_t flow A can reset the iterator while flow B is using it. The flow lock has no effect as flows share the htp_cfg_t. This has been observed in real traffic. hook_response_body_data was run on the same data multiple times, leading to corrupt extracted files.	12 years ago

Victor Julien	10a11b750d	Add dsize check to prefilter stage ... Many sigs with dsize have a weak fast_pattern. Those patterns are likely to match. By filtering on dsize early, we safe a lot of cycles later.	12 years ago
Victor Julien	45cbef0735	For signatures with the dsize option set depth on any content match in that sig.	12 years ago

Anoop Saldanha	b33986c887	Add a packet src for every packet generated inside suricata.	12 years ago
Eric Leblond	58bf4ea4a4	nfq: fix detection of type nfq_get_payload function.	12 years ago
Eric Leblond	19756488ab	nfq: close the queue when leaving acquisition. ... This patch adds a call to close the queue when the acquisition loop is ending. This way the incoming packets will be accepted during all the shutdown phase (if the queue-bypass option of NFQUEUE is used). At the same time the currently processed packets will be dropped but the time scale are different: suricata will drop 20 ms of packets and the shutdown can take 0.5 seconds. Patch based on an idea of Victor Julien.	12 years ago
Victor Julien	75cddabd8a	fast_pattern: don't consider http_method, http_stat_code and http_stat_msg when automatically giving preference to a HTTP pattern over a stream pattern.	12 years ago

Eric Leblond	c3b9a5e97f	pf-ring: add missing header.	12 years ago
Eric Leblond	7731cef782	pf-ring: protect definition of (un)likely ... This patch makes (un)likely declared if and only if they are not declared before.	12 years ago
Anoop Saldanha	fd977601b6	fix for bug #574. ... More of a temporary solution to prevent any possible FPs. Disable content inspection bypass for mpm patterns.	12 years ago
Anoop Saldanha	51c9955c79	fix for bug #577. ... If a pattern has matched on mpm, don't re-inspect it later, subject to certain conditions met by the pattern - namely, not negated, right chop, no replacet attached to it.	12 years ago

Victor Julien	33b0b07107	bug #572: make sure we use profiling fallback for all architectures except x86_64 and i386.	12 years ago
Victor Julien	50da0e80d5	Fix flow keyword compilation failure.	12 years ago
Anoop Saldanha	3d74fa964a	Update all flow referencing to use the new FlowReference and FlowDeReference ... macros.	12 years ago
Anoop Saldanha	6c68f86b8c	fix for bug #557. ... In FFRv2, dereference flow from a packet using the new reference/dereference util macros. This allows the decr use_cnt for flow and reseting the flow pointer to NULL for the pseudo pkt to happen simultaneously, in case there we fail to retrieve a pseudo_packet and have to return the already obtained pseudo packets, back to the packetpool.	12 years ago
Anoop Saldanha	88e89d6302	Introduce utility flow macros to help referencing/dereferencing flows.	12 years ago
Anoop Saldanha	4d501778e9	fix for bug #557. ... Reset hhd buffers list len if we exit before allocating the buffer.	12 years ago
Anoop Saldanha	855726f372	fix for bug #575. ... If sig has no_stream set, don't mask it as requiring flow. Should get rid of FNs any.	12 years ago

Eric Leblond	ffbbff9d6c	tm-thread: detect thread death ... When a thread is dead at init the THV_INIT_DONE flag is not set and the spawn function can freeze (see bug #553 for an example). In this case THV_RUNNING_DONE is set and we can also check on this state for leaving the function. This should fix #bug553	12 years ago
Victor Julien	af7f4b347d	threshold: improve comments of shipped threshold.config, add links to wiki.	12 years ago
Anoop Saldanha	4e3b206f7b	fix http server/client body handling. Update body status based on tx state.	12 years ago
Victor Julien	82fc61770b	threshold: allow threshold.config to override rule ... Allow threshold.conf to override rule thresholds in the following cases: - threshold.config rule uses threshold or event_filter AND - threshold.config rule applies to a single signature (so no gid 0 or sid 0) Confirmed to work with both threshold and detection_filter rule keywords. Part of bug #425.	12 years ago
