[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] #319: Changes Xprintf() formats to use PRIxyz, e.g., PRIu64, PRIx32

[Bro-Dev] #318: Use inttypes.h instead of home-made ifdefs

[Bro-Dev] #315: TCP Reassemblier type inconsistency

#315: TCP Reassemblier type inconsistency ----------------------+------------------------ Reporter: gregor | Owner: Type: Problem | Status: new Priority: Low | Milestone: Component: Bro | Version: git/master Keywords: inttypes | ----------------------+------------------------ {{{ #!rst The TCP Reassembler (and the general Reassembler which is the base class) have a type inconsitency: internally they define the sequence numbers as ``int``. When they have to compare seq numbers, they call ``seq_delta()`` which takes two ``uint32``.

[Bro-Dev] #317: Analyzer::Undelivered should use relative sequence numbers (and go to 64bit)

by Bro Tracker

#317: Analyzer::Undelivered should use relative sequence numbers (and go to 64bit) ----------------------+------------------------ Reporter: gregor | Owner: Type: Task | Status: new Priority: Normal | Milestone: Bro1.6 Component: Bro | Version: git/master Keywords: inttypes | ----------------------+------------------------ {{{ #!rst ``Analyzer::Undelivered(int seq, int len)`` is called with absolute TCP sequence from the TCP reassambler. However, since the analyzer framework should work on abstract byte streams, it should return *realtive* sequence numbers. In addition, it should use 64 bit integers! Note, that Undelivered is not really used. The HTTP.cc analyzer uses it, but ``seq`` is to generate a mime_content_gap event. It does seem that HTTP.cc assumes the seq number is relative.... }}} -- Ticket URL: <http://tracker.icir.org/bro/ticket/317> Bro Tracker <http://tracker.icir.org/bro> Bro Issue Tracker

[Bro-Dev] Masters updated

by Robin Sommer

I've updated all the masters and devels to - integrate a round of cleanup removing files no longer necessary. - the latest changes from SVN. I've also adapted the test-suite (in bro-private) to work with the new setup, and it passes fine with all the changes (well, to be precise, it reports the same differences as svn trunk; seems it's not completely up to date). We should now see if master is working for everybody. If so, we'll have a stable base to work from.

[Bro-Dev] Thoughts on documenting scripts

by Robin Sommer

I've added a page on how we might use Sphinx to auto-generate Bro script documentation to the projects list, see http://bro.icir.org/devel/projects/autodoc.html This includes a mock-up of how Sphinx input and output could look like. What do you guys think? Robin -- Robin Sommer * Phone +1 (510) 722-6541 * robin(a)icir.org ICSI/LBNL * Fax +1 (510) 666-2956 * www.icir.org
