This shouldn't make a difference, since rtadvd(8) is single-threaded, but I've seen it crash in delete_prefix() with pfx_rainfo == NULL, and this is the only place where a prefix can be added to the list with a NULL pfx_rainfo.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | added/removed interfaces in a more consistent manner and reloading the configuration file. - Implement burst unsolicited RA sending into the internal RA timer framework when AdvSendAdvertisements and/or configuration entries are changed as described in RFC 4861 6.2.4. This fixes issues that make termination of the rtadvd(8) daemon take very long time. An interface now has three internal states, UNCONFIGURED, TRANSITIVE, or CONFIGURED, and the burst unsolicited sending happens in TRANSITIVE. See rtadvd.h for the details. - rtadvd(8) now accepts non-existent interfaces as well in the command line. - Add control socket support and rtadvctl(8) utility to show the RA information in rtadvd(8). Dumping by SIGUSR1 has been removed in favor of it.

This change is a preparation to add support of dynamically-added/removed interfaces and the link status changes in a more reliable way.

DNS information received by rtsold(8) will go to resolv.conf(5) by resolvconf(8) script. Lifetime handling is not supported at this moment. Note: when receiving a link-local scope address rtsold(8) adds a scope id into addresses in the script arguments based on the received interface in a representation defined in RFC 4007 (e.g. fe80::1%bge0). However, there are some shell scripts using printf(1) (including resolvconf(8)) cannot process it properly because printf(1) can recognize the character % as special. Based on work by: J.R.
