[Bro-Dev] #340: Cleanup: unify where global consts are defined (access from policy layer and event engine)

by Bro Tracker

#340: Cleanup: unify where global consts are defined (access from policy layer and event engine) -----------------------------+-------------------- Reporter: gregor | Owner: Type: Feature Request | Status: new Priority: Low | Milestone: Bro1.6 Component: Bro | Version: Keywords: | -----------------------------+-------------------- {{{ #!rst Global ``const``'s that are accessible from the policy layer and event engine (e.g., to configure features) are currently defined in different ways: 1. in ``bro.init`` and ``NetVar.{cc|h}`` 2. in a specific .bro policy script and ``NetVar.{cc|h}`` 3. in ``const.bif`` According to our discussion on bro-dev, we should change it to only use ``const.bif``. For case 2. we should add a ``redef`` in the .bro policy scripts, so that users looking at the script see that the const exists (TODO: how to best auto-doucment these). Setting milestone to 1.6 as it seems this can be done together with the general policy script overhaul, but can also be pushed backed. }}} -- Ticket URL: <http://tracker.icir.org/bro/ticket/340> Bro Tracker <http://tracker.icir.org/bro> Bro Issue Tracker

[Bro-Dev] #370: Plugin interface for BroControl

by Bro Tracker

#370: Plugin interface for BroControl -----------------------------+-------------------- Reporter: seth | Owner: robin Type: Feature Request | Status: new Priority: Normal | Milestone: Bro1.6 Component: BroControl | Version: Keywords: | -----------------------------+-------------------- Features that a first version of the plugin interface should have... * Hooks to execute external scripts before and after start, stop, and install. * Mechanism for plugin scripts to provide feedback to BroControl. Maybe just succeed or fail+message would be enough? * Setting options for plugins in broctl.cfg. Maybe set ENV vars when running scripts? Currently, I'm thinking that using a naming convention for files in <prefix>/share/broctl/plugins would work for installing plugins. Names like this: post-install-plugin1 or pre-start-plugin2. That would provide BroControl enough information to know which configuration options to set in the environment when executing those scripts and when they are supposed to be executed. -- Ticket URL: <http://tracker.icir.org/bro/ticket/370> Bro Tracker <http://tracker.icir.org/bro> Bro Issue Tracker

[Bro-Dev] #361: Copy Bro binary only when in NFS mode

by Bro Tracker

#361: Copy Bro binary only when in NFS mode ------------------------+------------------------ Reporter: robin | Owner: robin Type: Task | Status: new Priority: Normal | Milestone: Bro1.6 Component: BroControl | Version: git/master ------------------------+------------------------ Currently, BroControl copies the bro binary to all clients' spool directory, and then runs it from there. While that avoids problems when the Bro installation is on NFS, it can cause trouble in other contexts (like capabilities set for the binary to be lost; and I think we had more in the past I don't recall right now). So, the solution seems to be to avoid the copy unless in NFS mode. We could also revisit whether we want to keep supporting runnign from NFS at all, but generall I'd like to do so. -- Ticket URL: <http://tracker.icir.org/bro/ticket/361> Bro Tracker <http://tracker.icir.org/bro> Bro Issue Tracker

[Bro-Dev] #326: HTTP Analyzer overflow on content-lengths > 2GB

by Bro Tracker

#326: HTTP Analyzer overflow on content-lengths > 2GB ----------------------+------------------------ Reporter: gregor | Owner: Type: Patch | Status: new Priority: Normal | Milestone: Bro1.6 Component: Bro | Version: git/master Keywords: inttypes | ----------------------+------------------------ {{{ #!rst The HTTP analyzer uses 32 bit signed ints to parse the content-length header, track body length etc. This causes overflow and for content lengths > 2GB. This effects the reported body length as well as parsing of pipelined or persistent connection. The overflow might also cause crashes. Changes in this patch: * Change the affected integers in to 64 bit wide * Overload min/max inline functions in util.h to work with different widths and signedness. * Explicitly cast parameters to min/max where in cases were the compiler complained. }}} -- Ticket URL: <http://tracker.icir.org/bro/ticket/326> Bro Tracker <http://tracker.icir.org/bro> Bro Issue Tracker

[Bro-Dev] #375: Extending record type fields

by Bro Tracker

#375: Extending record type fields -----------------------------+-------------------- Reporter: seth | Owner: Type: Feature Request | Status: new Priority: Normal | Milestone: Bro1.6 Component: Bro | Version: Keywords: logging | -----------------------------+-------------------- One proposal for giving users the ability to add their own fields to the record type used for logging to a particular stream in the new logging framework involves redef-ing the record type to add new fields. Example syntax: {{{ module SSH; type Log = record { client: string; server: string; } redef type SSH::Log += { id: conn_id &optional; }; }}} I'm even thinking that fields added in redefs could even be mandatory or implicitly &optional to avoid causing errors with shipped scripts. -- Ticket URL: <http://tracker.icir.org/bro/ticket/375> Bro Tracker <http://tracker.icir.org/bro> Bro Issue Tracker

[Bro-Dev] #374: Add type testing operator

by Bro Tracker

#374: Add type testing operator -----------------------------+-------------------- Reporter: seth | Owner: Type: Feature Request | Status: new Priority: Normal | Milestone: Bro1.6 Component: Bro | Version: Keywords: | -----------------------------+-------------------- This is needed for generic filtering of log records in the logging framework. Initial discussions have used a syntax like this: {{{ function generic_outbound(rec: any) { rec$?<conn_id>cid ... }}} That syntax would check that the record type instance 'rec' has a field named 'cid' with the type 'conn_id'. -- Ticket URL: <http://tracker.icir.org/bro/ticket/374> Bro Tracker <http://tracker.icir.org/bro> Bro Issue Tracker
