+# Building dhcpcd
+
+This attempts to document various ways of building dhcpcd for your
+platform.
+
+## Size is an issue
+To compile small dhcpcd, maybe to be used for installation media where
+size is a concern, you can use the `--small` configure option to enable
+a reduced feature set within dhcpcd.
+Currently this just removes non important options out of
+`dhcpcd-definitions.conf`, the logfile option and
+support for DHCPv6 Prefix Delegation.
+Other features maybe dropped as and when required.
+dhcpcd can also be made smaller by removing the IPv4 or IPv6 stack:
+ * `--disable-inet`
+ * `--disable-inet6`
+
+Or by removing the following features:
+ * `--disable-auth`
+ * `--disable-arp`
+ * `--disable-arping`
+ * `--disable-ipv4ll`
+ * `--disable-dhcp6`
+
+You can also move the embedded extended configuration from the dhcpcd binary
+to an external file (LIBEXECDIR/dhcpcd-definitions.conf)
+ * `--disable-embedded`
+If dhcpcd cannot load this file at runtime, dhcpcd will work but will not be
+able to decode any DHCP/DHCPv6 options that are not defined by the user
+in /etc/dhcpcd.conf. This does not really change the total on disk size.
+
+## Cross compiling
+If you're cross compiling you may need set the platform if OS is different
+from the host.
+`--target=sparc-sun-netbsd5.0`
+
+If you're building for an MMU-less system where fork() does not work, you
+should `./configure --disable-fork`.
+This also puts the `--no-background` flag on and stops the `--background` flag
+from working.
+
+## Default directories
+You can change the default dirs with these knobs.
+For example, to satisfy FHS compliance you would do this:
+`./configure --libexecdir=/lib/dhcpcd dbdir=/var/lib/dhcpcd`
+
+## Compile Issues
+We now default to using `-std=c99`. For 64-bit linux, this always works, but
+for 32-bit linux it requires either gnu99 or a patch to `asm/types.h`.
+Most distros patch linux headers so this should work fine.
+linux-2.6.24 finally ships with a working 32-bit header.
+If your linux headers are older, or your distro hasn't patched them you can
+set `CSTD=gnu99` to work around this.
+
+ArchLinux presently sanitises all kernel headers to the latest version
+regardless of the version for your CPU. As such, Arch presently ships a
+3.12 kernel with 3.17 headers which claim that it supports temporary address
+management and no automatic prefix route generation, both of which are
+obviously false. You will have to patch support either in the kernel or
+out of the headers (or dhcpcd itself) to have correct operation.
+
+## OS specific issues
+Some BSD systems do not allow the manipulation of automatically added subnet
+routes. You can find discussion here:
+ http://mail-index.netbsd.org/tech-net/2008/12/03/msg000896.html
+BSD systems where this has been fixed or is known to work are:
+ NetBSD-5.0
+ FreeBSD-10.0
+
+Some BSD systems protect against IPv6 NS/NA messages by ensuring that the
+source address matches a prefix on the recieved by a RA message.
+This is an error as the correct check is for on-link prefixes as the
+kernel may not be handling RA itself.
+BSD systems where this has been fixed or is known to work are:
+ NetBSD-7.0
+ OpenBSD-5.0
+ patch submitted against FreeBSD-10.0
+
+Some BSD systems do not announce IPv6 address flag changes, such as
+`IN6_IFF_TENTATIVE`, `IN6_IFF_DUPLICATED`, etc. On these systems,
+dhcpcd will poll a freshly added address until either `IN6_IFF_TENTATIVE` is
+cleared or `IN6_IFF_DUPLICATED` is set and take action accordingly.
+BSD systems where this has been fixed or is known to work are:
+ NetBSD-7.0
+
+OpenBSD will always add it's own link-local address if no link-local address
+exists, because it doesn't check if the address we are adding is a link-local
+address or not.
+
+Some BSD systems do not announce cached neighbour route changes based
+on reachability to userland. For such systems, IPv6 routers will always
+be assumed to be reachable until they either stop being a router or expire.
+BSD systems where this has been fixed or is known to work are:
+ NetBSD-7.99.3
+
+Linux prior to 3.17 won't allow userland to manage IPv6 temporary addresses.
+Either upgrade or don't allow dhcpcd to manage the RA,
+so don't set either `ipv6ra_own` or `slaac private` in `dhcpcd.conf` if you
+want to have working IPv6 temporary addresses.
+SLAAC private addresses are just as private, just stable.
+
+## Init systems
+We try and detect how dhcpcd should interact with system services at runtime.
+If we cannot auto-detect how do to this, or it is wrong then
+you can change this by passing shell commands to `--serviceexists`,
+`--servicecmd` and optionally `--servicestatus` to `./configure` or overriding
+the service variables in a hook.
+
+
+## /dev management
+Some systems have `/dev` management systems and some of these like to rename
+interfaces. As this system would listen in the same way as dhcpcd to new
+interface arrivals, dhcpcd needs to listen to the `/dev` management sytem
+instead of the kernel. However, if the `/dev` management system breaks, stops
+working, or changes to a new one, dhcpcd should still try and continue to work.
+To facilitate this, dhcpcd allows a plugin to load to instruct dhcpcd when it
+can use an interface. As of the time of writing only udev support is included.
+You can disable this with `--without-dev`, or `without-udev`.
+NOTE: in Gentoo at least, `sys-fs/udev` as provided by systemd leaks memory
+`sys-fs/eudev`, the fork of udev does not and as such is recommended.
+
+## select
+dhcpcd uses eloop.c, which is a portable main event loop with timeouts and
+signal handling. Unlike libevent and similar, it can be transplanted directly
+within the application - the only caveat outside of POSIX calls is that
+you provide queue.h based on a recent BSD (glibc sys/queue.h is not enough).
+eloop supports the following polling mechanisms, listed in order of preference:
+ kqueue, epoll, pollts, ppoll and pselect.
+If signal handling is disabled (ie in RTEMS or other single process
+OS's) then eloop can use poll.
+You can decide which polling mechanism dhcpcd will select in eloop like so
+`./configure --with-poll=[kqueue|epoll|pselect|pollts|ppoll]`
+
+
+## Importing into another source control system
+To prepare dhcpcd for import into a platform source tree (like NetBSD)
+you can use the make import target to create /tmp/dhcpcd-$version and
+populate it with all the source files and hooks needed.
+In this instance, you may wish to disable some configured tests when
+the binary has to run on older versions which lack support, such as getline.
+`./configure --without-getline`
+
+
+## Hooks
+Not all the hooks in dhcpcd-hooks are installed by default.
+By default we install `01-test`, `02-dump`, `10-mtu`, `20-resolv.conf`
+and `30-hostname`.
+The other hooks, `10-wpa_supplicant`, `15-timezone` and `29-lookup-hostname`
+are installed to `$(datadir)/dhcpcd/hooks` by default and need to be
+copied to `$(libexecdir)/dhcpcd-hooks` for use.
+The configure program attempts to find hooks for systems you have installed.
+To add more simply
+`./configure -with-hook=ntp.conf`
+
+Some system services expose the name of the service we are in,
+by default dhcpcd will pick `RC_SVCNAME` from the environment.
+You can override this in `CPPFLAGS+= -DRC_SVCNAME="YOUR_SVCNAME"`.
+This is important because dhcpcd will scrub the environment aside from `$PATH`
+before running hooks.
+This variable could be used to facilitate service re-entry so this chain could
+happen in a custom OS hook:
+ dhcpcd service marked inactive && dhcpcd service starts
+ dependant services are not started because dhcpcd is inactive (not stopped)
+ dhcpcd hook tests if `$if_up = true` and `$af_waiting` is empty or unset.
+ if true, mark the dhcpcd service as started and then start dependencies
+ if false and the dhcpcd service was previously started, mark as inactive and
+ stop any dependant services.
