This breaks the new feature in the interim since the router file
read is not yet supposed to read :slaac counterpart since the router
file is still read manually. Refactor to follow.
We do want to eventually lean on exclusive ifctl use in order to
be able to improve logic in ifctl or make adjustments really easy in
the future without missing a spot (e.g. adding scope to link-local
routers).
New script to be invoked by rtsold when Router Advertisements with
RDNSS / DNSSL information are received. Uses ifctl to create the
/tmp/$if_routerv6 file and creates the /tmp/$if_defaultgwv6 file
directly. Fixes the issue that these files don't get created when
the M and O flags in RAs are not set. Also, passes RDNSS / DNSSL
info from RAs to ifctl.
Just make a MD5 sum of the file and change polling to 20 seconds.
Call backend on first run as well without waiting. Interval could
be lower still, but as said earlier it doesn't matter much all
things considered.
Gets rid of package dependency which for dhcpleases6 simply
listens on the DHCPD lease file and runs the prefix.php command
unconditionally.
For now emulate this by issuing the command every 60 seconds
which can be adjusted later if someone complains, but seeing
how many bugs this script has had vs. how many people noticed
it (basically none) I doult this will have much impact overall.
'prefix' was never a key so this got never executed for whatever reason.
It remains broken in other projects and the question is if this script
really has any useful value.
Make sure to use a proper example from ISC dhcpd itself.
Here now we truncate the prefix and add the suffix, making
sure the suffix is correct. If the upper 64 bits are empty
we likely have the wrong format and we shift it up as
e.g. "::2" is not a prefix range value, but "::2:0:0:0:0" is.
Note that this is in contrast to static IPv6 where this has
to be configured correctly in the first place.
According to the manual "forever" is actually the correct keyword.
Also the double-pipe was senseless matching an empty expression
and there was a dash missing between month and day.
