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.
- Added the known-devices log, and the script to log DHCP hostname per MAC address,
- Added DPD sig,
- Removed some scripts following a discussion with Seth.
