Eric Leblond	640bc937b4	ebpf: add vlan tracking option to xdp_filter ... If vlan is not use for tracking in Suricata this result in vlan not being used in the flow key in Suricata and we need to adjust that in the XDP filter to avoid any problem.	6 years ago
Eric Leblond	34b8583f35	ebpf: tls encrypted bypass in xdp_filter ... Tests have shown that when we bypass encrypted traffic a non neglicteable amount of encrypted packets of the session are already in the capture ring buffer. Result is that Suricata is doing unnecessary work on these packets. These packets can be identified via the first bytes of their payloads so we can bypass them directly in the XDP code. This is done here for application data packets on port 443 and for TLS 1.2.	6 years ago

Eric Leblond	d239e0f2d5	flow-hash: doc and code cleaning	6 years ago
Eric Leblond	b736344975	flow-bypass: clock_gettime error handling ... Only reason clock_gettime could fail is a permission so let's error and leave the flow bypass manager if it is the case. Also let's suppress the error message if ever the error appear in the middle of a run (which is unlikely).	6 years ago

Eric Leblond	c1fd0da550	af-packet: add vlan_id in bypass key ... Bypassing on vlan was not supported due to the missing key.	6 years ago
Eric Leblond	651a27e4fb	ebpf: fix percpu hash handling ... An alignement issue was preventing the code to work properly. We introduce macros taken from Linux source code sample to get something that should work on the long term.	6 years ago
Eric Leblond	142c69e1ef	flow-bypass: increase bypass timeout ... This is needed as we did switch from counter maintained in kernel to internal polling so we need a bigger value.	6 years ago
Eric Leblond	b8e184ceb5	flow-bypass: fix timeout of maps bypassed flows ... The time is taken from the parameter and is checked against real flow entries so we need a standard time.	6 years ago

Eric Leblond	522e98d830	util-ebpf: fix iteration in flow timeout ... We were not setting the key using the correct item in map. Result was deletion of wrong flow.	6 years ago
Eric Leblond	f270e53477	ebpf: set number of RSS queues to a power of 2 ... This is needed as netronome can not do a division (so can't do a modulo) in hardware.	6 years ago
Eric Leblond	82c4f5135b	doc: use github mirror to setup libbpf	6 years ago
Eric Leblond	94bda5b7fb	ebpf: implement RSS load balancing in hardware mode	6 years ago
