4830bb6222 Fix compile without IPv6. 2015-12-03 20:43:41 +00:00
Roy Marples
56a660173f Add a -N --renew option to renew any existing address early, similar to the 
-n --rebind option. However, configuration is not reloaded.

Fixes [6cf818eeab].

3823dbf556 Backout commit [f20a30175f] as the behaviour can be trigged on Linux as well. 2015-07-22 09:59:32 +00:00

0723fb86aa Add a #define to compile ignoring the RA without a public address. 
This is set for BSD systems at present so that working systems such as Linux
work by default as designed.
Fixes [f44b3b4817].

time handling.

56db02ab49 Add a guard to ensure failure to send a DHCP release does not cause a double free via re-entering _drop(). 
Thanks to Todd Blanchard for the analysis.

d40f2f7b8d If we receieve an RA without a public prefix but with the Managed flag set, 
ignore the RA until we recieve a DHCPv6 lease with a public address at
which point it is applied.

f30470407c Allow the same IP address to be leased for different interfaces. 
The interface with the lowest metric gets the address.
When that interfaces loses the address, the next valid interface with the
lowest metric gets it.

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.
 2013-12-02 16:42:09 +00:00
Roy Marples
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).

the current transaction and re-discover.

336dd1b83b Move signal handling into dhcpcd.c 
Log the PID of the signal caller
Move syslog functions out of the signal handler if we're not
exiting as it's not safe.
Close existing IPv4 sockets when restarting an interface.
Fix control handling keeping current flags and accepting new ones.

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 :)

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.
