allow disabling "client fqdn" and "accept reconfiguration" options

Some DHCPv6 servers require these to be absent, so add
command line switches that allow disabling them.

(includes "Combination of command line switches -f and -a
 broke "-N none" and IA_PD." from Christian Carstensen)

10 years agoadd support for multiple prefixes with distinct IAIDs

add support for multiple prefixes with distinct IAIDs

Changes from v1:
- removed some unneeded changes
- use *_add_state instead of (semantically identical and so unnecessary)
  *_append_state

This is missing IAID validation for prefixes.

10 years agofix NTP server option handling

fix NTP server option handling

previously, only option 56 (NTP server) was supported, but named SNTP_*
throughout code and in the scripts environment. This patch fixes this and adds
optnion 31 (SNTP Servers) support. Uses NTP_IP and NTP_FQDN and SNTP_IP in

A few fixes for race conditions and similar problems

Fix race conditions in signal handling

Avoid several race conditions by using distinct variables for the different
signals. In particular different signals received in quick succession don't
overwrite each other any more, and odhcp6c_signal_process doesn't return true
anymore when a new SIGIO is received while another is still being processed.

Use getifaddrs to get the interface-id when not specified

Reimplementing this section also fixes two potential bugs:

1. Only link-local addresses should be used for automatic interface-id
   selection, as it should always be assigned by the kernel and is always based
   on the EUI-64 unless an administrator is doing strange things (while other
   addresses might be chosen according to the privacy extensions or by an
   administrator)
2. When no address is available (because of a race condition or because an
   administrator removed it), RA packets should just be ignored; otherwise
   an address with a zero interface-id might be assigned
