-This extension was generated by the Extension Wizard at
-http://ted.mielczarek.org/code/mozilla/extensionwiz/ .
-This extension is compatible only with Firefox 1.5 and
-above. Most of the files in this package are based on
-the 'helloworld' extension from the Mozillazine Knowledge Base.
-
-You can build an XPI for installation by running the
-build.sh script located in this folder. For development
-you should do the following:
- 1. Unzip the entire contents of this package to somewhere,
- e.g, c:\dev or /home/user/dev
- 2. Put the full path to the folder (e.g. c:\dev\bonjour4firefox on
- Windows, /home/user/dev/bonjour4firefox on Linux) in a file named
- bonjour4firefox@apple.com and copy that file to
- [your profile folder]\extensions\
- 3. Restart Firefox.
-
-For more information, see the Mozillazine Knowledge Base:

-Building the Bonjour Firefox Extension on Windows
-
-There is a Visual Studio 2005 project file that will build the extension correctly as long as the Visual Studio environment is setup correctly. This code was built against the 1.9 version of the XULRunner SDK. The Visual Studio environment should be modified to add the include and lib paths of the XULRunner SDK. Specifically, the following include paths should be added to VC++ include directories:
-
-…\xulrunner-sdk\include\xpcom
-…\xulrunner-sdk\include\nspr
-…\xulrunner-sdk\include\string
-…\xulrunner-sdk\include\pref
-…\xulrunner-sdk\sdk\include
-
-The following path should be added to VC++ lib directories:
-
-…\xulrunner-sdk\lib
-
-After the code has been built, it can be installed like any other Firefox extension. Please consult Firefox extension documentation for more information on how to package and install Firefox extensions.

+ * This is a Discovery Proxy module for the SRP gateway.
+ *
+ * The motivation here is that it makes sense to co-locate the SRP relay and the Discovery Proxy because
+ * these functions are likely to co-exist on the same node, listening on the same port. For homenet-style
+ * name resolution, we need a DNS proxy that implements DNSSD Discovery Proxy for local queries, but
+ * forwards other queries to an ISP resolver. The SRP gateway is already expecting to do this.
+ * This module implements the functions required to allow the SRP gateway to also do Discovery Relay.
+ *
+ * The Discovery Proxy relies on Apple's DNS-SD library and the mDNSResponder DNSSD server, which is included
+ * in Apple's open source mDNSResponder package, available here:
+ *
+ * https://opensource.apple.com/tarballs/mDNSResponder/

+ * The way it works is that this gateway listens on port ANY:53 and forwards either to another port on

+ * over both TCP and UDP in principle, but UDP requests should be from constrained nodes, and rely on

+ * Note that this is not a full DNS proxy, so you can't just put it in front of a DNS server.

+/** @brief Write a log message to system's log storage(memory or disk).
+ *
+ * On Apple platform, os_log() will be called to log a message.
+ *
+ * @param CATEGORY A custom log object previously created by the os_log_create function, and such an object is
+ * used to specify "subsystem" and "category". For mDNSResponder, the subsystem should always
+ * be set to "com.apple.mDNSResponder"; and the category is used for categorization and
+ * filtering of related log messages within the subsystem’s settings. We have 4 categories that
+ * are pre-defined: MDNS_LOG_CATEGORY_DEFAULT, MDNS_LOG_CATEGORY_MDNS, MDNS_LOG_CATEGORY_UDNS,
+ * MDNS_LOG_CATEGORY_SPS. If these categories are not enough, use os_log_create to create more.
+ *
+ * @param LEVEL The log level that determines the importance of the message. The levels are, in order of
+ * decreasing importance:
+ * MDNS_LOG_FAULT Fault-level messages are intended for capturing system-level errors
+ * that are critical to the system. They are always saved in the data store.
+ * MDNS_LOG_ERROR Error-level messages are intended for reporting process-level errors
+ * that are unexpected and incorrect during the normal operation. They
+ * are always saved in the data store.
+ * MDNS_LOG_WARNING Warning-level messages are intended for capturing unexpected and
+ * possible incorrect behavior that might be used later to root cause
+ * an error or fault. They are are initially stored in memory buffers
+ * and then moved to a data store.
+ * MDNS_LOG_DEFAULT Default-level messages are intended for reporting things that might
+ * result a failure. They are are initially stored in memory buffers
+ * and then moved to a data store.
+ * MDNS_LOG_INFO Info-level messages are intended for capturing information that may
+ * be helpful, but isn’t essential, for troubleshooting errors. They
+ * are initially stored in memory buffers, but will only be moved into
+ * data store when faults and, optionally, errors occur.
+ * MDNS_LOG_DEBUG Debug-level messages are intended for information that may be useful
+ * during development or while troubleshooting a specific problem, Debug
+ * logging should not be used in shipping software. They are only
+ * captured in memory when debug logging is enabled through a
+ * configuration change.
+ *
+ * @param FORMAT A constant string or format string that produces a human-readable log message. The format
+ * string follows the IEEE printf specification, besides the following customized format specifiers:
+ * %{mdnsresponder:domain_name}.*P the pointer to a DNS lable sequence
+ * %{mdnsresponder:ip_addr}.20P the pointer to a mDNSAddr variable
+ * %{network:in_addr}.4P the pointer to a mDNSv4Addr variable
+ * %{network:in6_addr}.16P the pointer to a mDNSv6Addr variable
+ * %{mdnsresponder:mac_addr}.6P the pointer to a 6-byte-length MAC address
+ *
+ * @param ... The parameter list that will be formated by the format string. Note that if the customized
+ * format specifiers are used and the data length is not specified in the format string, the
+ * size should be listed before the pointer to the data, for example:
+ * "%{mdnsresponder:domain_name}.*P", (name ? (int)DomainNameLength((const domainname *)name) : 0), <the pointer to a DNS label sequence>

+ // fix, and so the advice if someone runs into this and considers it a problem should be to

+ // Another issue with this code is that at present, we do not wait for more than one SRV
+ // record--we cancel the query as soon as the first one comes in. This isn't ideal: it
+ // would be better to wait until we've gotten all our answers and then pick the one with

- the system configuration settings for Dynamic DNS and Wide-Area DNS-SD,
- and (ii) the right to write to the system keychain to store Dynamic DNS
- shared secrets used to perform authorized updates to DDNS servers.
- Right now these are both actually the same right: "system.preferences"

* cannot be shared by copying them and using kDNSServiceFlagsShareConnection.

- * 4. Don't Double-Deallocate if the MainRef has been Deallocated
- * Calling DNSServiceRefDeallocate(ref) for a particular operation's DNSServiceRef terminates

* After doing this, DO NOT then attempt to deallocate any remaining subordinate DNSServiceRef's.
* The memory used by those subordinate DNSServiceRef's has already been freed, so any attempt
* to do a DNSServiceRefDeallocate (or any other operation) on them will result in accesses
* to freed memory, leading to crashes or other equally undesirable results.
+ * You can deallocate individual operations first and then deallocate the parent DNSServiceRef last,
+ * but if you deallocate the parent DNSServiceRef first, then all of the subordinate DNSServiceRef's
+ * are implicitly deallocated, and explicitly deallocating them a second time will lead to crashes.
*
* 5. Thread Safety
* The dns_sd.h API does not presuppose any particular threading model, and consequently
* If the client concurrently, from multiple threads (or contexts), calls API routines using
* the same DNSServiceRef, it is the client's responsibility to provide mutual exclusion for
* that DNSServiceRef.
-
+ *
* For example, use of DNSServiceRefDeallocate requires caution. A common mistake is as follows:
* Thread B calls DNSServiceRefDeallocate to deallocate sdRef while Thread A is processing events
* using sdRef. Doing this will lead to intermittent crashes on thread A if the sdRef is used after
* it was deallocated.
-
+ *
* A telltale sign of this crash type is to see DNSServiceProcessResult on the stack preceding the
* actual crash location.
-

* To state this more explicitly, mDNSResponder does not queue DNSServiceRefDeallocate so
* that it occurs discretely before or after an event is handled.

* conventional DNS escaping rules, as used by the traditional DNS res_query() API, as described below:
*
* Generally all UTF-8 characters (which includes all US ASCII characters) represent themselves,
- * with two exceptions, the dot ('.') character, which is the label separator,
- * and the backslash ('\') character, which is the escape character.
+ * with three exceptions:
+ * the dot ('.') character, which is the DNS label separator,
+ * the backslash ('\') character, which is the DNS escape character, and
+ * the ASCII NUL (0) byte value, which is the C-string terminator character.
* The escape character ('\') is interpreted as described below:
*
* '\ddd', where ddd is a three-digit decimal value from 000 to 255,
* For example, the ASCII code for 'w' is 119, and therefore '\119' is equivalent to 'w'.
* Thus the command "ping '\119\119\119.apple.com'" is the equivalent to the command "ping 'www.apple.com'".
* Nonprinting ASCII characters in the range 0-31 are often represented this way.
- * In particular, the ASCII NUL character (0) cannot appear in a C string because C uses it as the
- * string terminator character, so ASCII NUL in a domain name has to be represented in a C string as '\000'.
+ * In particular, the ASCII NUL character (0) cannot appear in a C-string because C uses it as the
+ * string terminator character, so ASCII NUL in a domain name has to be represented in a C-string as '\000'.
* Other characters like space (ASCII code 32) are sometimes represented as '\032'
- * in contexts where having an actual space character in a C string would be inconvenient.
+ * in contexts where having an actual space character in a C-string would be inconvenient.
*
* Otherwise, for all cases where a '\' is followed by anything other than a three-digit decimal value
* from 000 to 255, the character sequence '\x' represents a single literal occurrence of character 'x'.
* followed by neither a three-digit decimal value from 000 to 255 nor a single character.
* If a lone escape character ('\') does appear as the last character of a string, it is silently ignored.
*
+ * The worse-case length for an escaped domain name is calculated as follows:
+ * The longest legal domain name is 256 bytes in wire format (see RFC 6762, Appendix C, DNS Name Length).
+ * For our calculation of the longest *escaped* domain name, we use
+ * the longest legal domain name, with the most characters escaped.
+ *
+ * We consider a domain name of the form: "label63.label63.label63.label62."
+ * where "label63" is a 63-byte label and "label62" is a 62-byte label.
+ * Counting four label-length bytes, 251 bytes of label data, and the terminating zero,
+ * this makes a total of 256 bytes in wire format, the longest legal domain name.
+ *
+ * If each one of the 251 bytes of label data is represented using '\ddd',
+ * then it takes 251 * 4 = 1004 bytes to represent these in a C-string.
+ * Adding four '.' characters as shown above, plus the C-string terminating
+ * zero at the end, results in a maximum storage requirement of 1009 bytes.
+ *
* The exceptions, that do not use escaping, are the routines where the full
* DNS name of a resource is broken, for convenience, into servicename/regtype/domain.
* In these routines, the "servicename" is NOT escaped. It does not need to be, since
* is invalidated when this function is called - the DNSRecordRef may not be used in subsequent
* functions.
*
+ * If the reference was passed to DNSServiceSetDispatchQueue(), DNSServiceRefDeallocate() must
+ * be called on the same queue originally passed as an argument to DNSServiceSetDispatchQueue().

- * type ("regtype") will discover it. If the discovery should be
- * restricted to a smaller set of well known peers, the service can be
- * registered with additional data (group identifier) that is known
- * only to a smaller set of peers. The group identifier should follow primary
- * service type using a colon (":") as a delimeter. If subtypes are also present,
- * it should be given before the subtype as shown below.
- *
- * % dns-sd -R _test1 _http._tcp:mygroup1 local 1001
- * % dns-sd -R _test2 _http._tcp:mygroup2 local 1001
- * % dns-sd -R _test3 _http._tcp:mygroup3,HasFeatureA local 1001
- *
- * Now:
- * % dns-sd -B _http._tcp:"mygroup1" # will discover only test1
- * % dns-sd -B _http._tcp:"mygroup2" # will discover only test2
- * % dns-sd -B _http._tcp:"mygroup3",HasFeatureA # will discover only test3
- *
- * By specifying the group information, only the members of that group are
- * discovered.
- *
- * The group identifier itself is not sent in clear. Only a hash of the group
- * identifier is sent and the clients discover them anonymously. The group identifier
- * may be up to 256 bytes long and may contain any eight bit values except comma which
- * should be escaped.
- *
* domain: If non-NULL, specifies the domain on which to advertise the service.
* Most applications will not specify a domain, instead automatically
* registering in the default domain(s).

-#
-# Prior to building Java support, you must build DNSSD.dll.
-#
-# nmake with no arguments builds all production targets.
-# 'nmake DEBUG=1' to build debugging targets.
-# 'nmake clean' or 'nmake clean DEBUG=1' to delete prod/debug objects & targets

-# To run nmake, you may need to set up your PATH correctly, using a script

-#
-# The default location of the JDK is \javasdk. You can override this on the

-#
-# Prior to building Java support, you must build DNSSD.dll.
-#
-# nmake with no arguments builds all production targets.
-# 'nmake DEBUG=1' to build debugging targets.
-# 'nmake clean' or 'nmake clean DEBUG=1' to delete prod/debug objects & targets

-# To run nmake, you may need to set up your PATH correctly, using a script

-#
-# The default location of the JDK is \javasdk. You can override this on the

-This directory contains support files for running mDNS on Microsoft Windows
-and Windows CE/PocketPC. Building this code requires the Windows SDK 2003
-or later. The CodeWarrior builds require CodeWarrior 8 or later and if using
-CodeWarrior 8, the newer Windows headers from the Mac CodeWarrior 9 need to
-be used.
-
-mDNSWin32.c/.h
-
- Platform Support files that go below mDNS Core. These work on both Windows
- and Windows CE/PocketPC.
-
-DNSSD.c/.h
-
- High-level implementation of the DNS-SD API. This supports both "direct"
- (compiled-in mDNSCore) and "client" (IPC to service) usage. Conditionals
- can exclude either "direct" or "client" to reduce code size.
-
-DNSSDDirect.c/.h
-
- Portable implementation of the DNS-SD API. This interacts with mDNSCore
- to perform all the real work of the DNS-SD API. This code does not rely
- on any platform-specifics so it should run on any platform with an mDNS
- platform plugin available. Software that cannot or does not want to use
- the IPC mechanism (e.g. Windows CE, VxWorks, etc.) can use this code
- directly without any of the IPC pieces.
-
-RMxClient.c/.h
-
- Client-side implementation of the DNS-SD IPC API. This handles sending
- and receiving messages from the service to perform DNS-SD operations
- and get DNS-SD responses.
-
-RMxCommon.c/.h
-
- Common code between the RMxClient and RMxServer. This handles establishing
- and accepting connections, the underying message sending and receiving,
- portable data packing and unpacking, and shared utility routines.
-
-RMxServer.c/.h
-
- Server-side implementation of the DNS-SD IPC API. This listens for
- and accepts connections from IPC clients, starts server sessions, and
- acts as a mediator between the "direct" (compiled-in mDNSCore) code
- and the IPC client.
-
-DNSServices is an obsolete higher-level API for using mDNS. New code should
-use the DNS-SD APIs.
-
-DNSServiceDiscovery is an obsolete emulation layer that sits on top of
-DNSServices and provides the Mac OS X DNS Service Discovery API's on any
-platform. New code should use the DNS-SD APIs.
-
-Tool.c is an example client that uses the services of mDNS Core.
-
-ToolWin32.mcp is a CodeWarrior project (CodeWarrior for Windows version 8).
-ToolWin32.vcproj is a Visual Studio .NET 7 project. These projects build
-Tool.c to make DNSServiceTest.exe, a small Windows command-line tool to do all
-the standard DNS-SD stuff on Windows. It has the following features:
-
-- Browse for browsing and/or registration domains.
-- Browse for services.
-- Lookup Service Instances.
-- Register domains for browsing and/or registration.
-- Register services.
-
-For example, if you have a Windows machine running a Web server,
-then you can make it advertise that it is offering HTTP on port 80
-with the following command:
-
-DNSServiceTest -rs "Windows Web Server" "_http._tcp." "local." 80 ""
-
-To search for AFP servers, use this:
-
-DNSServiceTest -bs "_afpovertcp._tcp." "local."
-
-You can also do multiple things at once (e.g. register a service and
-browse for it so one instance of the app can be used for testing).
-Multiple instances can also be run on the same machine to discover each
-other. There is a -help command to show all the commands, their
-parameters, and some examples of using it.
-
-DNSServiceBrowser contains the source code for a graphical browser application
-for Windows CE/PocketPC. The Windows CE/PocketPC version requires Microsoft
-eMbedded C++ 4.0 with SP2 installed and the PocketPC 2003 SDK.

- To Do:
-
- - Get unicode name of machine for nice name instead of just the host name.
- - Use the IPv6 Internet Connection Firewall API to allow IPv6 mDNS without manually changing the firewall.
- - Get DNS server address(es) from Windows and provide them to the uDNS layer.
- - Implement TCP support for truncated packets (only stubs now).

-The mdnsNSP is a NameSpace Provider. It hooks into the Windows name resolution infrastructure to allow any software using the standard Windows APIs for resolving names to work with DNS-SD. For example, when the mdnsNSP is installed, you can type "http://computer.local./" in Internet Explorer and it will resolve "computer.local." using DNS-SD and go to the web site (assuming you have a computer named "computer" on the local network and advertised via DNS-SD).
-
-NSP's are implemented DLLs and must be installed to work. NSP DLLs export an NSPStartup function, which is called when the NSP is used, and NSPStartup provides information about itself (e.g. version number, compatibility information, and a list of function pointers for each of the supported NSP routines).
-
-If you need to register the mdnsNSP, you can use the NSPTool (sources for it are provided along with the mdnsNSP) with the following line from the DOS command line prompt ("<path>" is the actual parent path of the DLL):
-
-NSPTool -install "mdnsNSP" "B600E6E9-553B-4a19-8696-335E5C896153" "<path>"
-
-You can remove remove the mdnsNSP with the following line:
-
-NSPTool -remove "B600E6E9-553B-4a19-8696-335E5C896153"
-
