Haywood 0 siblings, 1 reply; 4+ messages in thread From: Enrico Weigelt @ 2007-11-30 11:57 UTC (permalink / raw) To: netfilter team Hi folks, while tracking some problems with an pynix based distro (they've changed some bit in the kernel<->userland interface), I wondered why netfilter doesn't do the kernel interface entirely via an synthetic filesystem (or maybe within sysfs). IMHO evrything could be very easy if the netfilter objects (tables, chains, rules, etc) were represented by an fs tree. For example we would have no binary dependencies between kernel and userland. I'm currently playing around with Plan9 and 9P. It's amazing how simple things can be if evrything's (really!) a file :) cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ --------------------------------------------------------------------- ^ permalink raw reply [flat|nested] 4+ messages in thread

More than once a day ? And is it really that much more expensive to call sscanf() than first creating the netlink packages and later parsing them again ? cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ --------------------------------------------------------------------- ^ permalink raw reply [flat|nested] 4+ messages in thread
