- Detect and adapt to resolv.conf changes through the use of the new
res_check() API, so that for example changing the search list doesn't
require restarting clients.
- A persistent mdnsd connection pool, with slow start (so that
programs like ping, ssh, etc don't keep connections open) and age-out.
NOTE: Tuning parameter values are just SWAGs.
try. No point in making queries and waiting for timeouts on lookups that
will never succeed.
Now only does lookups for linklocal addresses (v4 or v6) and
"name.local" names (and dotless names, iff "local" is specified in the
resolv.conf search list).
Also, lower the timeout in this mode, since multicast lookups should
return pretty fast or not at all.
- nss_mdns renamed to nss_multicast_dns for clarity and less chance of
confusion with nss_mdnsd (see next).
- Support using mdnsd for all unicast too with new nss_mdnsd module
(note: this mode requires an updated mdnsd too, not yet committed)
- Implement resolv.conf "search" directive support. Needed for nss_mdnsd,
potentially useful with nss_multicast_dns (you could now do
"search example.com local" in resolv.conf if you wanted to and it would
act as you might expect)
- Add references in nsswitch.conf man page and sample file
- Implement AI_CANONNAME
- Various bug fixes
debug and packet trace logging.
Make this conditional on HAVE_SIGINFO. Presumably lack of SIGINFO as a
standard posix feature is why they went with different signals here in
the first place, but since we have it, let's use it.
- Enhance the built-in drop-privs support and use it instead of
having the rc.conf do it. Avoids log error on startup.
From OpenSolaris, with enhancements.
- Add dumping of the unicast server list to the DumpStateLog
debugging output, a'la Mac OS X.
- Fix a locking botch that caused warnings in the log.
- Fix FILE leak. From OpenSolaris.
- Build with MDNS_VERSIONSTR_NODTS a'la OpenSolaris, to exclude
__DATE__/__TIME__, for repeatable builds.
- log under "mdnsd" instead of "mDNSResponder" to reduce confusion.
