of the base system init.
However, the user can easily flip between them so we need to work out
which init system is in use at runtime rather than compile time.
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.
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).
Install dhcpcd-embedded.conf to LIBEXECDIR which is read before dhcpcd.conf.
The idea is that this dhcpcd-embedded.conf is maintained only by me to support
RFC DHCP/DHCPv6 options that require known embedded or ncapsulated options
which are not easily added to our option structures in dhcp.c and dhcp6.c.
Eventually we may move the whole structure here so that a smaller binary
is produced and the definitions are easier to maintain.
can go into dev.c
Create a new struct to pass dhcpcd handle_interface to dev plugins
This allows us to build the dhcpcd binary normally and save a few k
disk space.
I was going to go with ppoll(2) because I would guess the Open Group
would prefer the name of it over pollts(2) if they ever standardised it.
However that causes a problem with _GNU_SOURCE and my code base so I've
gone to pollts(2) and suck in the compat header for Linux users to avoid
that sillyness.
ppoll is mapped to pollts(2) for supporting systems.
If pselect(2) is available then we provide a compat shim for that, otherwise
we provide a non race free shim based on poll(2).
posix_spawn(3).
Now we block all our signals at startup and allow pselect to
unblock them for the duration of the call. This allows us to
manage interrupts in a fashion to guarantee a consistent
internal state.
I have added a posix_spawn compat shim for systems that lack
that call. pselect(2) has been supported on target for some time
so there is no need for a compat shim there.
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.
