2020-06-21examples/udhcp/simple.script: fix IPv6 support when using udhcpcStefan Agner
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.

2019-04-13examples/udhcp/simple.script: fix resolv.conf update if it is a dangling symlinkRolf Eike Beer
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.

2013-03-12udhcpc: use readlink rather than realpathMike Frysinger
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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-02-27udhcpc: tweak math shell style with the metric varMike Frysinger
Some shells (like dash) are lame and omit the POSIX increment/decrement feature (because it is listed as optional). Tweak the shell script to work in all POSIX variants. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-02-27udhcpc: support resolv.conf symlinksMike Frysinger
Often it is desirable to have /etc/ be on read-only storage (well, the whole rootfs) but have things like /etc/resolv.conf be symlinks to a writable location. Tweak the simple script to support that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

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.
