rtm_newaddr masks off OPTIMISTIC.
inet6_rtm_newaddr(struct sk_buff *skb, struct nlmsghdr *nlh)
...
/* We ignore other flags so far. */
ifa_flags &= IFA_F_NODAD | IFA_F_HOMEADDRESS | IFA_F_MANAGETEMPADDR |
IFA_F_NOPREFIXROUTE;
Is there any problem or not allowed?
I need to do something like adding a route for the address after adding the
address but fails because the address is not useable yet.
I tried NODAD but there's still little delay until IFA_F_TENTATIVE is cleared.
- rtm_newaddr sets IFA_F_TENTATIVE
- set a timer for dad start with delay=0
- some delay
- dad starts but ends immediately because of NODAD flag, and clears
TENTATIVE.
And it looks like OPTIMISTIC does what I need but kind of disabled like the
code above.
Thanks,
Soohoon.
