[Bro-Dev] Feedback on configuration framework implementation

by Johanna Amann

Hello everyone, the branch topic/johanna/config contains an implementation of the configuration framework as it was discussed in an earlier thread on this list. GitHub link: https://github.com/bro/bro/compare/topic/johanna/config The implementation is basically what we discussed in the earlier thread with some additional components like a reader for configuration values and a script-level framework. It would be great if people could take a look at all of this and see if this makes sense, or if they see any problems with the implementation as it is at the moment. In the rest of the mail I wil go into a bit more detail and describe the different parts of this change. Note that the rest of this email will be very similar to the git commit message which also describes this change :) The configuration framework consists of three mostly distinct parts: * option variables * the config reader * the script level framework option variable =============== The option keyword allows variables to be specified as run-tine options. Such variables cannot be changed using normal assignments. Instead, they can be changed using Option::set. It is possible to "subscribe" to options and be notified when an option value changes. Change handlers can also change values before they are applied; this gives them the opportunity to reject changes. Priorities can be specified if there are several handlers for one option. Example script: option testbool: bool = T; function option_changed(ID: string, new_value: bool): bool { print fmt("Value of %s changed from %s to %s", ID, testbool, new_value); return new_value; } event bro_init() { print "Old value", testbool; Option::set_change_handler("testbool", option_changed); Option::set("testbool", F); print "New value", testbool; } config reader ============= The config reader provides a way to read configuration files back into Bro. Most importantly it automatically converts values to the correct types. This is important because it is at least inconvenient (and sometimes near impossible) to perform the necessary type conversions in Bro scripts themselves. This is especially true for sets/vectors. Configuration generally look like this: [option name][tab/spaces][new variable value] so, for example: testaddr 2607:f8b0:4005:801::200e testinterval 60 testtime 1507321987 test_set a b c d erdbeerschnitzel The reader uses the option name to look up the type that variable has in the Bro core and automatically converts the value to the correct type. Example script use: type Idx: record { option_name: string; }; type Val: record { option_val: string; }; global currconfig: table[string] of string = table(); event InputConfig::new_value(name: string, source: string, id: string, value: any) { print id, value; } event bro_init() { Input::add_table([$reader=Input::READER_CONFIG, $source="../configfile", $name="configuration", $idx=Idx, $val=Val, $destination=currconfig, $want_record=F]); } Script-level config framework ============================= The script-level framework ties these two features together and makes them a bit more convenient to use. Configuration files can simply be specified by placing them into Config::config_files. The framework also creates a config.log that shows all value changes that took place. Usage example: redef Config::config_files += {configfile}; export { option testbool : bool = F; } The file is now monitored for changes; when a change occurs the respective option values are automatically updated and the value change is written to config.log. Other changes ============= Internally, this commit also performs a range of changes to the Input manager; it marks a lot of functions as const and introduces a new ValueToVal method (which could in theory replace the already existing one - it is a bit more powerful). This also changes SerialTypes to have a subtype for Values, just as Fields already have it; I think it was mostly an oversight that this was not introduced from the beginning. This should not necessitate any code changes for people already using SerialTypes. Johanna

[Bro-Dev] Log::set_buf Ineffective Before First Write

by Logan Lembke

Hello, I am currently writing a Bro IDS logging plugin for logging to MongoDB. We have implemented both buffered and unbuffered writes and rely on WriterBackend::DoSetBuf to be called in order to switch between the approaches. Currently, we use a bro script which attaches our plugin to the Conn log and calls Log::set_buf in order to configure the buffering behavior. However, DoSetBuf never gets called on our plugin. In Manager.cc, Manager::SetBuf loops over the list of writers registered with a given stream and calls the SetBuf method on each of the WriterFrontends. Unfortunately, this list of registered writers is empty before the first write, as writers are initialized as they are needed in the Manager::Write method. Effectively, this prevents configuring buffering behavior before the first write occurs. I'm new to the Bro code base, but I believe a fix could be made by storing the buffering behavior on the stream and checking this behavior on writer initialization. Here is the bro script I am currently using, The source code for the plugin is at https://github.com/ocmdev/bro-mongodb/tree/optionalBuffer. Does this look like a valid problem? Logan

Re: [Bro-Dev] [Bro-Commits] [git/bro] topic/actor-system: First-pass broker-enabled Cluster scripting API + misc. (07ad06b)

by Robin Sommer

This is coming together quite nicely. Not sure if it's stable yet, but I'll just go ahead with some feedback I noticed looking over the new cluster API: - One thing I can't quite tell is if this is still aiming to maintain compatibility with the old communication system, like by keeping the proxies and also the *_events patterns. Looking at setup-connections, it seems so. I'd say just go ahead and remove all legacy pieces. Maintain two schemes in parallel is cumbersome, and I think it's fine to just force everything over to Broker. - Is the idea for the "*_topic" constants that one just picks the apppropiate one when sending events? Like if I want to publish something to all workers, I'd publish to Cluster::worker_topic? I think that's fine, though I'm wondering if we could compress the API there somehow so that Cluster doesn't need to export all those constants indvidiually. One idea would be a function that returns a topic based on node type? - I like the Pools! How about moving Pool with its functions out of the main.bro, just for clarity. - Looks like the hello/bye events are broadcasted by all nodes. Is that on purpose, or should that be limited to just one, like just the master sending them out? Or does it not matter and this provides for more redundancy? - create_store() vs "stores": Is the idea that I'd normally use create_store() and that populates the table, but I could also redef it myself instead of using create_store() to create more custom entries? If so, maybe make that a bit more explicit in the comments that there're two ways to configure that table.

[Bro-Dev] Scientific notation?

by Seth Hall

Right now, Bro will print scientific notation in JSON logs but we've always tended to avoid it in the standard Bro log format. What does everyone think about switching to allow scientific notation in the standard log format? Daniel recently did some exploration of various versions of awk and they all support scientific notation (I think that was part of my concern a long time ago). Thoughts? .Seth -- Seth Hall * Corelight, Inc * www.corelight.com

[Bro-Dev] File Analysis Inconsistencies

by Aaron Eppert

I crafted a custom file analysis plugin that attaches to specific MIME types via file_sniff and fires an appropriate event once processing has been completed. I had to jump through a few hoops to make a file analysis plugin, first, but those were cleared and everything runs and loads appropriately there (bro -NN verified.) My test regime is very straight forward, I have several PCAPs cooked up that contain simple HTTP file GETs (that extract otherwise properly and do not exhibit missing_bytes) and I am running them via `bro -C -r <>.pcap`. My issue comes with utter and complete inconsistency with execution - it is, effectively, a coin flip, with zero changes. When I have dumped the buffers being processed, as my file analysis plugin has a secondary verification to make sure the data passed is appropriate - which is confusing, as the mime type fires correct, which seems to indicate a bug somewhere in the data path - the correct execution, clearly has the proper data in it. The invalid executions, again changing nothing other than a subsequent execution, shows a buffer of what appears to be completely random data. I currently cannot supply the file analysis plugin for inspection, but would very much appreciate insight in how to find the root cause. It very much seems to be upstream. If I run the analysis portion of the plugin as a free standing executable outside of Bro against the data transferred via HTTP, everything works perfect and the structures are filled accordingly. I saw BIT-1832, and there could be similar root causes in there, but I have not had time to investigate otherwise. The issues I am raising, again, are command line replay via command line, not even “live” network traffic or tcpreplay over a NIC/dummy interface. Aaron
