* ipv6: Add IFA_F_DADFAILED flagBrian Haley2009-09-111-0/+1
| | | | | | | | | | | | | Add IFA_F_DADFAILED flag to denote an IPv6 address that has failed Duplicate Address Detection, that way tools like /sbin/ip can be more informative. 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 2001:db8::1/64 scope global tentative dadfailed valid_lft forever preferred_lft forever Signed-off-by: Brian Haley <brian.haley@hp.com> Signed-off-by: David S.

* [IPV6] ADDRCONF: Optimistic Duplicate Address Detection (RFC 4429) Support.Neil Horman2007-04-251-0/+1
| | | | | | | | | | | | | | | | | Nominally an autoconfigured IPv6 address is added to an interface in the Tentative state (as per RFC 2462). Addresses in this state remain in this state while the Duplicate Address Detection process operates on them to determine their uniqueness on the network. During this period, these tentative addresses may not be used for communication, increasing the time before a node may be able to communicate on a network. Using Optimistic Duplicate Address Detection, autoconfigured addresses may be used immediately for communication on the network, as long as certain rules are followed to avoid conflicts with other nodes during the Duplicate Address Detection process.

* [NETLINK]: Put {IFA,IFLA}_{RTA,PAYLOAD} macros back for userspace.David S. Miller2006-12-081-0/+6
| | | | | | | | | | GLIBC uses them etc. They are guarded by ifndef __KERNEL__ so nobody will start accidently using them in the kernel again, it's just for userspace. Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6] ADDRCONF: Mobile IPv6 Home Address support.Noriaki TAKAMIYA2006-09-221-0/+1
| | | | | | | | | | | | | | IFA_F_HOMEADDRESS is introduced for Mobile IPv6 Home Addresses on Mobile Node. The IFA_F_HOMEADDRESS flag should be set for Mobile IPv6 Home Addresses for 2 purposes. 1) We need to check this on receipt of Type 2 Routing Header (RFC3775 Secion 6.4), 2) We prefer Home Address(es) in source address selection (RFC3484 Section 5 Rule 4).

* [IPV6] ADDRCONF: Allow non-DAD'able addresses.Noriaki TAKAMIYA2006-09-221-0/+1
| | | | | | | | | | | | | IFA_F_NODAD flag, similar to IN6_IFF_NODAD in BSDs, is introduced to skip DAD. This flag should be set to Mobile IPv6 Home Address(es) on Mobile Node because DAD would fail if we should perform DAD; our Home Agent protects our Home Address(es).
