IPVS network namespace aware ?

IPVS network namespace aware ?

[Hans Schillstrom]

Hello
Is there any one that have made ipvs network namespace aware ?
There is an urgent need of it within Ericsson.
I could not find any trace of it in any of the normal lists.

I will start patching ipvs next week or give a helping hand to any
existing work.

Regards
Hans Schillstrom

Hi Hans,

I am not aware of any other work in this area.
Please send any patches here :-)

Hi Hans,

do you have a patchset ready (or just a prototype) ? I will be glad to 
help you ;)

Thanks

Hi Daniel
The progress is good, so far I think everything is ported except for
Simon Hormans latest patch-set. 

Right now I'm struggling with NULL pointers :-)
i.e. seq_file doesn't carry any netns info.

In the example below *net will be invalid because seq->private is NULL.

static void *ip_vs_info_seq_next(struct seq_file *seq, ....) {
struct net *net = seq_file_net(seq);

single_open() seems to work, but seq_open() or seq_open_private().

As you can see I'm not ready, so help will be nice.
I'll remove some debugging stuff and send you a patch-set.

/Hans

I have found it, local usage of seq->private.
When the admin part works, (hopefully to morrow) I will send the patch
