Valerio G 18499fd7d9 Extend DHCP protocol analyzer with new options. ... Add the folowing option types: - 55 Parameters Request List; - 58 Renewal time; - 59 Rebinding time; - 61 Client Identifier; - 82 Relay Agent Information. Extend the following events with new parameters, specifically: - dhcp_discover exports client identifier and parameters request list; - dhcp_request exports client_identifier and parameters request list; - dhcp_ack exports rebinding time, renewal time and list of suboptions value of dhcp relay agent information option; - dhcp_inform exports parameters request list. Add option type specific variables within the scope of DHCP module (see src/analyzer/protocol/dhcp/types.bif). Move protocol specific variables "dhcp_msg" and "dhcp_router_list" from scope Global to DHCP:: and adapt inet_net_var in src/NetVar.cc consequently. Extend src/analyzer/protocols/dhcp/main.bro to handle the new events and to log dhcp_ack, dhcp_request and dhcp_discover. Modify scripts/policy/protocols/dhcp/known-devices-and-hostnames.bro to include new events' variables.		2018-01-08 21:53:58 +01:00
