Luajit has a strange memory requirement, it's 'states' need to be in the
first 2G of the process' memory.
This patch improves the pool approach by moving it to the front of the
start up.
A new config option 'luajit.states' is added to control how many states
are preallocated. It defaults to 128.
Add a warning when more states are used then preallocated. This may fail
if flow/stream/detect engines use a lot of memory. Add hint at exit that
gives the max states in use if it's higher than the default.
Add SCStreamingBuffer lua function to retrieve the data passed
to the script per streaming API invocation.
Example:
function log(args)
data = SCStreamingBuffer()
hex_dump(data)
end
A new callback to give access to thread id, name and group name:
SCThreadInfo. It gives: tid (integer), tname (string), tgroup (string)
function log(args)
tid, tname, tgroup = SCThreadInfo()
SCRuleIds(): returns sid, rev, gid:
function log(args)
sid, rev, gid = SCRuleIds()
SCRuleMsg(): returns msg
function log(args)
msg = SCRuleMsg()
SCRuleClass(): returns class msg and prio:
function log(args)
class, prio = SCRuleClass()
if class == nil then
class = "unknown"
end
Add flow store and retrieval wrappers for accessing the flow through
Lua's lightuserdata method.
The flow functions store/retrieve a lock hint as well.
