413652c1b3 Instead of linking directly to libudev, create a plugin system for /dev 
management. This allows dhcpcd to work even if udev removed and adds the
ability to change from udev to something else in the future.

which protocols to wait for.

77961e7b99 Add an option to respect whatever the server says for the hostname. 
Change the default back to FQDN as per RFC4702 section 3.1.

d6a1865476 Add the option hostname_short, which will force the sending of the 
short hostname so DDNS will always work, even if the hostname domain
is different from the DHCP servers.

Change hostname_fqdn to true/false/unset value.
unset means use what the DHCP server supplies
 (DHCPv4/DHCPv6 maybe inconsistent depending on server setup)
true/false force the hostname to be either a FQDN or a short name.

b8ffa3cd19 Map DHCPv4 options to DHCPv6 where applicable. 
This makes for an easier configuration.
Send the FQDN option by default.

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.

5985c4e2a6 Allow ia_pd interfaces to be specified without a SLA. 2013-06-03 22:02:51 +00:00
Roy Marples
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 :)

367f7b11b4 Refactor Prefix Delegation configuration so we use integers instead 
of hex based arrays.
The SLA can now be applied to any router given prefix length provided the
SLA can fit into the prefix and desired prefix length.
We now wait for a carrier and LL address before adding the addresses from the
delegated prefix. Before adding this code, I added some code to generate a
LL address from the hardware address. This is now #ifdef'ed out as I don't
want to throw it away in-case dhcpcd ever needs to create LL addresses
itself.

Many thanks to Martin Husemann who developed code for these functions:
	ipv6_userprefix, in6_to_h64 and h64_to_in6
which are used to generate a prefix from the delegated prefix and the SLA

7dab081fbe Add the noalias directive to so that when adding an IPv4 addresss 
dhcpcd will overwrite a pre-existing address.

4c6a8becec If we have one interface enabled for IPv6 RS, we stupidly process 
RAs for all interfaces we control. This patch fixes this and
updates the man page to reflect this better.
 2013-02-05 10:15:59 +00:00
Roy Marples
d7555c1259 Add DHCPv6 INFORM support. 
This is automatically started when RA flags O is set.
If no DHCPv6 request options are configured in dhcpcd.conf then we
request domain servers and search lists.

eebe9a1887 Improve IPv6 RA support by allowing dhcpcd to manage the address and routes 
instead of the kernel. dhcpcd will only do this if RA is disabled in the kernel
or dhcpcd has been instructed to do this via dhcpcd.conf(5) ipv6ra_own and
ipv6ra_own_default directives.

Send and process IPv6 Neighbor Solicitions and Adverts to prove router
reachability. If a router cannot be reached in this way then it is expired.

When debugging, all ND messages are displayed which will create a lot of log
spam.

To ease packaging, ./configure now accepts LDFLAGS and --enable-static.

fd73ceb145 Add .Lk macro to URLs 2012-03-19 11:07:56 +00:00
Roy Marples
61dd6cf9ab Add an option to control dhcpcd forking or not if the RA does not contain 
a RDNSS option.
This involves changing our options to an unsigned long long so we can use
more than 32 bits.
 2012-03-07 10:06:45 +00:00

91cd732493 Add an implementation of an IPv6 Router Solicitor as specified in 
RFC6016 with regards to RDNSS and DNSSL.

499225e43f Change default reboot timeout to 5 seconds. 
When rebooting and we haven't daemonised, reduce the discover timeout
to allow for fallback or IPv4LL addresses.

4242c9b3dd -H, --xidhwaddr will use the last four bytes of the hardware address 
as the xid instead of generating a random number.

2a07a2afd8 Add back -w, --waitip so that user has total control over behaviour. 2009-10-16 19:59:30 +00:00
Roy Marples
355889a91c Remove the -w option and make it the default action if at least one 
interface reports a carrier.

cea7dcafce wait -> waitip 
It's more descriptive and allows future wait$entity commands.
 2009-10-13 06:02:30 +00:00

21090e3d1d -w, --wait forces dhcpcd to wait for an ip address or timeout when 
running on more than one interface.

6bfd88f171 -e, --env var=value 
now pushes var=value to the environment when dhcpcd-run-hooks is run.
This allows the possibility to set env vars that hook scripts can work off.
A good example of this is 30-hostname so that force_hostname=YES can set
the hostname regardless of the current hostname.

--reconfigure now takes the short option -g.

35d02ae670 Documentation updates. 
A few minor corrections, but mainly updates the expected behaviour for the hostname being sent.
 2009-07-25 17:57:49 +00:00

bf80d52682 Add -W, --whitelist addr/cidr 
This only allows packets from the addresses listed and overrides
blacklist if set.

6f767217f6 Add the ability to arping an address and select a profile based on the 
hardware address replied with or the ip address.

1abffd5ba5 We can now detected primary addresses added or changed in BSD. 
As such, we can wait for a 3RDPARTY to configure the interface, such as PPP.
We can then take the destination addess and automatically give it a default
route or any other DHCP option such as DNS servers.
This addresses #159.

ce6b39df64 We need to blacklist IP addresses at the packet level 
so we can ignore NAKs from rogue servers who don't
supply a ServerID, or supply a fake one.
