94a79cea05 If not specified, Delegated Prefixes will get an automatic SLA of the 
interface index. If the biggest SLA and the assigned prefix fits into a /64
then dhcpcd creates a /64 prefix so that SLAAC works. If bigger than /64
is needed then dhcpcd creates one rounded upto the nearest multiple of 8.

Unless a configured SLA of 0 is assigned, a reject route for the Delegated
Prefix is installed to stop unassigned addresses trying to be resolved upstream.

Addresses added from Delegated Prefixes now have a default address suffix of 1
instead of using a SLAAC style address.

4eb7b4896f Move all global variables into contexts, with a small exception for 
signal handling.
This allows dhcpcd to work better in a threaded environment such as rtems.

ae4e592fa2 Remove hard coded DHCP/DHCPv6 options and then to dhcpcd-definitions.conf 
This file replaces dhcpcd-embedded.conf
This actually results in a slightly smaller binary than before and has the
added advantage that the option definitions are now all held within one file.

1cd05a96d5 Read the embedded config into global values rather than each time 
per interface.

Add config toggles to build dhcpcd-embedded.conf into dhcpcd or
to read it at runtime. The build process will now build .c and .h
files based on dhcpcd-embedded.conf and provide defines to reduce
the number or re-allocs if it grows (ie has the full DHCP option list).

cc3c3560f6 Add DHPCv6 FQDN support (RFC4704) 
Improve hostname support in general, so we are aware of hostname changes.
When setting the hostname, prefer the FQDN name or append a domain.

22ea2b0deb Automate the assignment of SLA ids if not given for Prefix Delegation. 
This means you can just request an ia_pd and let dhcpcd do the rest :)

d128d95214 Build BOUND routes before DELEGATED ones.

d8194bcd39 Check address flags for tentative and duplicates bits for sanity. 
Handle the actual trigger to callout dhcpcd-run-hooks in the DAD callback
instead of on receipt of RTM_NEWADDR directly. This is more code, but it allows
us to use our own DAD engine if we need to.
 2013-05-16 10:31:21 +00:00

a8df1b28fb Use the kernel DAD for IPv6 addresses and finish the action once each 
address DAD completes. BSD kernels will require a patch as noted within
the README. The linux netlink part still needs to be written.
