Isn''t it possible with iptables to filter on DSCP field? Thanks, Tom Aernoudt

Hi all, Is it allowed to use the @llvm.lifetime.end intrinsic to optimize away stores to global variables that are used as temporaries? eg I want use the Jit engine to generate code for the following function 'f': struct State { int a; int tmp; int b; }; void f0(State* s) { s->tmp = s->a; } void f1(State* s) { s->b = s->tmp; } void f(State* s) { f0(s); f1(s); }

...tc filter add dev eth0 parent ffff:1 protocol ip prio 1 handle 1 fw classid ffff:1 But the DSCP value isn''t set correctly. What''s wrong with it? If I try to mark the packets at the outgoing interface then the DSCP value is set. Why doesn''t it work at the ingress? Tom Aernoudt

...ex classid 2:161 $TC filter add dev $DEV parent 2:0 protocol ip prio 1 \ handle 6 tcindex classid 2:6 </bigger> But I can''t combine the two. What do I have to do to combine these 2? I tried to do the marking at the ingress but that didn''t work. Thanks, Tom Aernoudt
