examples/udhcp/simple.script: fix IPv6 support when using udhcpc

2020-06-21T01:02:02+00:00

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

2019-04-13T14:58:00+00:00

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. Signed-off-by: Rolf Eike Beer Signed-off-by: Denys Vlasenko

examples/udhcp/simple.script: add possibility to use modern "ip"

2018-10-30T11:05:03+00:00

Script uses "ifconfig" only, not up-to-date so much. This patch adds "ip" in condition if exists. Signed-off-by: Jiří Prchal Signed-off-by: Denys Vlasenko

udhcpc: use readlink rather than realpath

2013-03-12T14:48:09+00:00

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

udhcpc: tweak math shell style with the metric var

2013-02-27T06:05:34+00:00

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

udhcpc: support resolv.conf symlinks

2013-02-27T06:01:43+00:00

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
