Add a lua callback for getting Suricata's log path, so that lua scripts
can easily get the logging directory Suricata uses.
Update the Setup logic to register callbacks before the scripts 'setup'
is called.
Example:
name = "fast_lua.log"
function setup (args)
filename = SCLogPath() .. "/" .. name
file = assert(io.open(filename, "a"))
end
Add file logger support. The script uses:
function init (args)
local needs = {}
needs['type'] = 'file'
return needs
end
The type is set to file to make it a file logger.
Add utility functions for placing things on the stack for use
by the scripts. Functions for numbers, strings and byte arrays.
Add callback for returing IP header info: ip version, src ip,
dst ip, proto, sp, dp (or type and code for icmp and icmpv6):
SCPacketTuple
Through 'needs' the script init function can indicate it wants to
see packets and select a condition function. Currently only alerts
is an option:
function init (args)
local needs = {}
needs["type"] = "packet"
needs["filter"] = "alerts"
return needs
end
