examples/udhcp/simple.script: fix IPv6 support when using udhcpc
...
The udhcpc script calls ip addr flush .. which flushes addresses
of any address family, including IPv6. However, busybox udhcpc is
IPv4 only and should not influence IPv6 addressing. Hence use ip
addr flush with family constraint.
The script particularly broke IPv6 SLAAC: Typically when udhcpc
calls the script the kernel already assigned the IPv6 link-local
address. The flush removes the link-local IPv6 address again and
prohibits proper IPv6 operation such as SLAAC since neighbor
discovery protocol relies on IPv6 link-local addressing.

examples/udhcp/simple.script: fix resolv.conf update if it is a dangling symlink
...
If /etc/resolv.conf is a symlink to a tmpfs and the actual file does not
already exist, "readlink -f" will not detect it as symlink. Explicitely check
for that condition before and touch the file, making the other code work as
intended.

udhcpc: use readlink rather than realpath
...
The realpath utility requires all paths exist when canonicalizing
symlinks. If /etc/resolv.conf points to a tmpfs, then it might
not exist initially. Use `readlink -f` so that we follow all
symlinks that are available.

Erik,
Attached is a patch for the udhcpc sample scripts, to correct the order in
which routers are applied if the DHCP server provides more than one (as per
section 3.5 of RFC2132).
Apologies for not being on the mailing list and thanks for your continued
efforts.
Simon.

Hello,
Here's a patch for a first attempt at static leases for udhcpd.
Included in the tarball are 2 files (static_leases.c, static_leases.h)
and a patch against the latest cvs.
In the config file you can configure static leases with the following
format:
static_lease 00:60:08:11:CE:4E 192.168.0.54
static_lease 00:60:08:11:CE:3E 192.168.0.44
Comments/suggestions/improvements are welcome.
