After my netfilter presentation at linuxtag, somebody was asking me exactly this question. > Apart from the technical issues, would there be any problems? Does the GPL > allow this kind of usage? (it would be implemented as a module) This is basically the same question like binary-only kernel modules. The GPL just talks about linking with libraries, since it was written at the time people were working on userspace programs. Linus has generally given his permission, that his code might be called from binary-only kernel modules Rusty has always made it very clear, that he doesn't share this view and he has never given permission for people using any of his code from binary- only modules. Having netfilter within a different kernel, is technically the same: GPL'd netfilter/iptables code is called from a binary-only kernel. Thus, my conclusion would be: Without the explicit permission of the authors, it is legally not possible to use netfilter/iptables within a proprietary OS kernel. But of coursel, I am not a lawyer. I for myself are somewhat undecided, but I tend to share Rusty's view: I haven't ever given permission for using my code by binary only kernel modules. All new code I'm working on wil export GPLONLY to make sure about that. > ps: don't tell me to use ipfilter (which works on Solaris), it's awful I don't share this opinion, but this doesn't matter - it's off-topic. > Bazsi -- Live long and prosper - Harald Welte / [EMAIL PROTECTED] http://www.gnumonks.org/ ============================================================================ GCS/E/IT d- s-: a-- C+++ UL++++$ P+++ L++++$ E--- W- N++ o?
