Is anyone using http.request_line successfully?
When specifying in my init function:
needs["http.request_line"] = tostring(true)
And a match function that only performs a syslog to verify it's being called - I \
don't receive the message. But changing 'http.request_line' to any of the other \
buffers (ex: 'http.request_headers') then I do receive the syslog message. I don't \
get any errors either when using http.request_line. I found this odd since this is \
the example on the website: \
https://redmine.openinfosecfoundation.org/projects/suricata/wiki/Lua_scripting
I verified that it doesn't work in the dev-lua branch, as well as not working in \
2.0.1 and 1.4.6. It doesn't appear to be a typo since that causes an error on \
startup if a bad buffer is specified. It also doesn't appear to be an issue with my \
syslog message since I get the syslog message when using a different buffer.
My rule if that matters:
alert tcp any any -> any any (msg:"HTTPRequestLine"; luajit:HTTP_Request_Line.lua; \
sid:312339;)
Am I missing something obvious? I'd be surprised if this was broken since 1.4.6 but \
I can submit a bug if that's the case.
Thanks,
Paul
