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.
