33Multicast DNS and Service Discovery support in illumos using the
34Apple Bonjour source code (v107.6). Apple Bonjour source can be
35downloaded from:
36	https://opensource.apple.com/tarballs/mDNSResponder/
37The following components are integrated from the Apple Bonjour
38source in illumos:
39  libdns_sd:	usr/src/lib/libdns_sd <dns_sd.h>
40  mdnsd:	usr/src/cmd/cmd-inet/usr.lib/mdnsd
41  dns-sd:	usr/src/cmd/cmd-inet/usr.bin/dns-sd
42
43Following fixes have been made to the Apple Bonjour source
44integrated in illumos:
45* 64-bit support by adding pad bytes in ipc_msg_hdr_struct
46* 64-bit support in libjdns_sd, dnssd.jar (JNISupport.c, DNSSD.java)
47* mdnsd switches to user 'noaccess' and not 'nobody' after init
48* Fixes to support IPv6 (mDNSPosix.c, mDNSUNP.c)
49* Fix error raised when uDNS.c is compiled with Sun Studio compiler
50* Fix in dnssd_clientstub.c to not check errno when recvmsg returns 0
51* mDNSDebug.c modified to not send msgs directly to console when
52  syslog call returns an error. Logs the messages at LOG_INFO level
53  and not LOG_ERR
54
55In addition the project introduces the following changes:
56* A new nss_mdns module is introduced to use Multicast DNS (mdns)
57  for resolving link-local hostnames and is located at:
58    usr/src/lib/nsswitch/mdns
59* snoop updated to decode mDNS packets
60* updated /etc/services to include mdns
61* <netinet/in.h> updated to include mdns
62* svc:/network/dns/multicast:default introduced to manage mDNS daemon
63* solaris.smf.manage.mdns & solaris.smf.value.mdns authorizations
64  to modify nss_mdns configuration in svc:/network/dns/multicast:default
65  Both authorizations added in network management execution profile.
66* Default nsswitch.dns includes mdns as source for hosts & ipnodes
67* nscd daemon updated to support mdns
68* SUNWdsdu and SUNWdsdr packages deliver all the new mDNS
69  service discovery components.
