No inter-module communication possible? Ideally, I’d configure one of the qdiscs to know the handle and device¹ of another, and then its .change op would call the .change op (or a special function) from the other, but I lack sufficient Linux kernel experience (even locking for SMP is something I always fear to miss). ① it really would help if just the handle is enough; they are practically global (in my setup) anyway because they determine the debugfs filename Alternatively, the ability to run multiple tc commands without having to do multiple fork/exec of the binary would help. Maybe even a “continuous” mode, in which the binary would REPL commands from stdin, running them as they’re read… Thanks in advance, //mirabilos -- Infrastrukturexperte • tarent solutions GmbH Am Dickobskreuz 10, D-53121 Bonn • http://www.tarent.de/ Telephon +49 228 54881-393 • Fax: +49 228 54881-235 HRB AG Bonn 5168 • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg **************************************************** /⁀\ The UTF-8 Ribbon ╲ ╱ Campaign against Mit dem tarent-Newsletter nichts mehr verpassen: ╳ HTML eMail!
