f94b4eab06 Use strtoi(3) and strtou(3) from NetBSD-8 instead of the harder to use 
strtol(3) calls.
Add shims around strtoimax(3) and strtoumax(3) when these functions
are not available.

182b3db0e8 Only extend temporary addresses with pltime. 
If the Prefix Information Option has zero pltime, set all temporary addresses
with a pltime to zero for the prefix.

515dd1616f Revert part of the prior patch and only free IPv6 if state when 
freeing and not dropping so we retain IPv6 addresses we don't
generally control on carrier down.

drop and free or just free IPv6 temporary addresses.

4b18b8403c Restore IFA_F_MANAGETEMPADDR 2015-01-19 13:28:26 +00:00
Roy Marples
727cd92aaf Change define KERNEL_MANAGETEMPADD to IPV6_MANAGETEMPADDR. 
Use this to block out actual address additions so we don't get bogus errors
about not being able to create temporary addresses.

70193d0a9a Now that ipv6 has it's own eloop, ensure that we clear any interface 
timeout when freeing the IPv6 state.

7e16d38e99 Fix which interface to test ip6_use_tempaddr on when adding. 2015-01-18 20:34:57 +00:00
Roy Marples
a1f7b32cef Implement RFC4941, Privacy Extensions for Stateless Address Autoconfiguration 
in IPv6 when dhcpcd is overriding the in-kernel RA support.

For Linux kernels (3.18+) which support IFA_F_MANAGETEMPADDR the bulk of
this changeset is compiled out and the kernel will manage the temporary
addresses entirely.

For BSD, this is a fully compliant implementation with the caveat
that when dhcpcd is restarted the last non deprecated temp address on the
interface will be treated as being created when it was last updated
rather when it was actually added. Thus this may voilate section 3.3.
As dhcpcd won't restart in normal operation, this isn't an issue.

For Linux (3.18+) which supports IFA_F_MANAGETEMPADDR, the bulk of this
changeset is compiled out as the kernel will manage the temporary addresses.
For older Linux this is a fully compliant implementation with the caveat that
when restarted new temporary addresses will be generated.

3852009b98 For BSD systems stop polling for IPv6 router reachability. 
This didn't work on all BSD platforms and where it did work,
it didn't work reliably.
Instead, expect for cached neighour route additions/changes/removals to be
announced by the kernel.
Currently only NetBSD-7.99.3 supports this so this is added to the README.
