[Netnice-kernels] netnice on linux

[kartikey b. <kar...@ho...>]

hi taka,

Before I commit my further patches I'd like to ask you a few questions 
regarding netnice in particular and on linux.

1. Is it really necessary that we allow fine grain control over sockets too? 
I mean whether each individual socket should have its own association to 
vifs? What I am doing is rather than associating vifs to each socket , i am 
associating the vif to process only and the so_vifnet in socket is a pointer 
to the list of associated vifs of the process. And this way the system is 
more consistent.

2. I am enforcing that each process should have at least (and at most) one 
vif associated with the real net_device (ifnet in FreeBSD terminology). So a 
process cannot have more than "1" or less than "1" vif associated with eth0 
at any given time. Whenever a process creates a vif, I am not allocating a 
new p_vifnet rather I am modifying the p_vifnet that is already associated 
with the vif that connects process to the real net_device (interface). When 
a process deletes the vif it simply reverts the p_vifnet to the vif that was 
associated with it before the creation of new vif.

I know that these two approaches are not consistent with the way netnice is 
implemented on FreeBSD. However, they give a consistent view of the vif 
system.
Any feedback?

thanks
