for the namespace (assuming the socket domain will be ok for all the
operations).
Jamal, I don't know what kind of application you want to use but if I
assume you want to create a process controlling 1024 netns,
At the moment i am looking at 8K on a Nehalem with lots of RAM. They
will mostly
than just some basic locking only while you change the struct net
pointer to the new namespace for these sub-subsystems?

are evolving
and synchronizing via user space is the best approach. The example
of route table i pointed to is simple.
Besides that: dynamic state created in the kernel that doesnt have to be
recreated by the next arriving 100K packets helps to improve recovery.

Yes. My intention is that current-nsproxy-net_ns

Well, example what is being un/shared etc.

Routing already works fine. I

Lets just ignore the need for these changes since the patch fixes them
for now. I would still like to make the changes i suggested but later
with more thought put into them.

Yes please - even if it is for reasons of givein Jarek some peace of

If something goes seriously wrong with other classifiers because of the
patch

If you want to do this - go ahead; else i plan on tackling it probably

the cause
in such a situation.
Here's the anology of our conversation (some captured above) as i see it
centred around a bug of leaky pipe which just messed up the carpet
overnight in some room:
handyman Jamal: fix the pipe so it doesnt leak.
handyman Jarek: put a little bucket below
to:

an existing tp because it succeeded in parameter change.
So the soln is to check if this is a new tp and then do what you did
