The code has been drastically re-arranged.
Instead of populating a custom structure while parsing dhcp messages, we now pluck what we need right out of the message itself. We have custom functions and a lookup table to make this really easy.
This makes us more like dhclient and udhcpc, and will enable us to easily add (and remove!) more dhcp options without having to actually change the code (much).
We now store the real dhcp message we got in /var/db/dhcpcd-$iface.lease, the mtime of the file being used as when we got the lease. This file is read in when re-using an old lease instead of parsing the .info file.
The benefit of all of this means that we're actually ~15k smaller when compiled with the same features.
This has been tested for quite some time, and I'm pretty sure most bugs with the 3.2 branch have been fixed whilst making this. Right now, we are 99% command line compatible with the 3.2 branch.
Compile and work on OSX/Darwin.
If we have no fork then we re-exec ourselves with --daemonised.
Improved the build system so we automatically detect if we need
librt or libresolv and if fork() works or not.
Move back to using librt for clock_gettime on Linux systems.
intervals like we do otherwise.
We now return a non zero exit code on SIGTERM and SIGINT if we have not
forked into the background.
When NIS and/or NTP servers are updated, we restart the service for them
if we can.
-n and -G options now work as stated in the man page.
Handle select loops with large timeouts and infinite lease times.
Correctly set the broadcast flag.
make_dhcp_packet already has byte ordered addresses, thanks to TGL
for the fix.
If we get a NAK then always re-enter the INIT state.
