94bec97280 Namespace all public dhcpcd.c functions. 
Add ipv4, ipv6, dhcp and dhcp6 options to re-enable if disabled globally.
Try and load a delegated interface if not running on all interfaces.
Fix delegated interfaces without a prefix set.

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.

9a243eb205 Fix assignment error from strcpy removal. 2014-03-06 19:30:30 +00:00

7529fdf1af Tentative does not mean RTM_DELADDR. 
This fixes RTM address handling on FreeBSD and OpenBSD.

Instead of listening for duplicate address messages for
FreeBSD and OpenBSD simply poll for the address flag changing.
This means less code to maintain and hopefully less error-prone.

Remove dead code which send a DAD as this is, and should,
be done entirely in the kernel.

98d7a13dfa When deleting IPv6 addresses, remove them from our internal address state 
as well so we perform DAD when rebinding.
Remove debug added with prior commit.

4145d2b68a Expire DHCP lease and then run no carrier as a seperate operation. 
Instead of waiting the maximum amount of time to report DAD failure/completion, poll the address flags periodically.

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.

cc0502023e Remove custom set_cloexec and set_nonblock functions. 
Instead pass O_CLOEXEC or SOCK_CLOEXEC to open, socket, etc.
This requires a fairly modern system.
