Re: [PATCH] IPv6addr: Support a parameter to specify interface name
[In reply to]

Hi Kazunori-san,
Eventhough I know that backward compatibility with Linux-HA v1 may not be the most important issue, is your modification compatible with v1 ? In other words, how can a v1 user declare the 'nic' to be used for IPv6 addresses ?
For IPv4, a v1 user had to declare its IP address as follows: <ip>/<prefix-len>/<interface> (ex: 135.9.8.7/24/eth0).
Now, would it be possible to declare IPv6 addresses in the same way ?
Ex: IPv6addr::3ffe:1111:2222:3333:4444:5556:6666:7777/64/eth0
That's what was done in the patch I proposed a few months ago (the patch you link to in your mail). Unfortunately, it appeared that my patch was too 'v1 oriented' ;) and Dejan asked me to add v2 support before re-submitting it. I had a look at what to do for this, without success (I'm quite a newbie about Linux-HA). Without more time to devote on this issue, I put it aside. I'm glad you raised the issue again ;). Now, I would be very thankful if your patch could fix this problem for v1 users too (unless it does it already). Maybe a solution could be to allow both ways to add the 'nic': via the parameter 'nic' or by appending it at the end the IPv6 address string. What do you think ?
Thanks and regards
Pascal ANDRE
