Implementation has been based on code, - comments and feedback provided November and December of 2008 by Daniel - Stenberg, Gregor Jasny, Phil Blundell and myself, December 2009 by Cedric - Bail, and February 2010 by Jakub Hrozek on the c-ares mailing list. On - March I reviewed all that, selected the best of each, and adjusted or - extended parts of it to make the best fit. - - The external and visible result of all this is that two new functions are - added to the external API, ares_get_servers() and ares_set_servers(), which - becomes now the preferred way of getting and setting name servers for any - ares channel as these support both IPv4 and IPv6 name servers. - - In order to not break ABI compatibility, ares_init_options() with option - mask ARES_OPT_SERVERS and ares_save_options() may still be used in code - which is intended to run on IPv4-only stacks. But remember that these - functions do not support IPv6 name servers. This implies that if the user - is capable of defining or providing an IPv6 name server, and the app is - using ares_init_options() or ares_save_options() at some point to handle - the name servers, the app will likely loose IPv6 name servers. - -* January 28, 2010 (Daniel Stenberg) -- Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't - check for broken connections like ares_process() did. Based on that, I - merged the two functions into a single generic one with two front-ends. - -* December 29, 2009 (Yang Tse) -- Laszlo Tamas Szabo adjusted Makefile.msvc compiler options so that where - run-time error checks enabling compiler option /GZ was used it is replaced - with equivalent /RTCsu for Visual Studio 2003 and newer versions. Option - /GX is replaced with equivalent /EHsc for all versions. Also fixed socket - data type for internal configure_socket function. - -* December 21, 2009 (Yang Tse) -- Ingmar Runge noticed that Windows config-win32.h configuration file - did not include a definition for HAVE_CLOSESOCKET which resulted in - function close() being inappropriately used to close sockets. - -Version 1.7.0 (Nov 30, 2009) - -* November 26, 2009 (Yang Tse) -- Larry Lansing fixed ares_parse_srv_reply to properly parse replies - which might contain non-SRV answers, skipping over potential non-SRV - ones such as CNAMEs. - -* November 23, 2009 (Yang Tse) -- Changed naming convention for c-ares libraries built with MSVC, details - and build instructions provided in README.msvc file. - -* November 22, 2009 (Yang Tse) -- Jakub Hrozek fixed more function prototypes in man pages to sync them - with the ones declared in ares.h - -- Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and - ares_addr6ttl in order to prevent name space pollution, along with - necessary changes to code base and man pages.This change does not break - ABI, there is no need to recompile existing applications. But existing - applications using these structs with the old name will need source code - adjustments when recompiled using c-ares 1.7.0. - -* November 21, 2009 (Yang Tse) -- Added manifest stuff to Makefile.msvc. - -* November 20, 2009 (Yang Tse) -- Fixed several function prototypes in man pages that were out of sync - with the ones declared in ares.h. Added ares_free_data() along with - man page. Updated ares_parse_srv_reply() and ares_parse_txt_reply() - with changes from Jakub Hrozek making these now return linked lists - instead of arrays, and merging the ares_free_data() adjustments. - -* November 10, 2009 (Yang Tse) -- Updated MSVC 6.0 project files to match settings from Makefile.msvc. - -* November 9, 2009 (Yang Tse) -- Makefile.msvc is now the reference method to build c-ares and sample - programs with any MSVC compiler or MS Visual Studio version. If no - option or target are specified it builds dynamic and static c-ares - libraries in debug and release flavours and also builds all sample - programs using each of the different c-ares libraries. - -* November 2, 2009 (Yang Tse) -- Renamed c-ares setup.h to ares_setup.h - -* October 31, 2009 (Yang Tse) -- Symbol hiding configure options are named now --enable-symbol-hiding - and --disable-symbol-hiding in an attempt to make them less ambiguous. - -* October 30, 2009 (Yang Tse) -- Many fixes for ares_parse_txt_reply() - -* October 29, 2009 (Daniel Stenberg) -- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing - -* October 29, 2009 (Yang Tse) -- Updated MSVC 6.0 workspace and project files that allows building - dynamic and static c-ares libraries in debug and release flavours. - Additionally each of the three sample programs is built against - each of the four possible c-ares libraries, generating all this - a total number of 12 executables and 4 libraries. - -* October 28, 2009 (Yang Tse) -- Initial step towards the ability to reduce c-ares exported symbols - when built as a shared library based on the 'visibility' attribute - for GNUC and Intel compilers and based on __global for Sun compilers, - taking also in account __declspec function decoration for Win32 and - Symbian DLL's. - -* October 27, 2009 (Yang Tse) -- Fixed Pelles C Win32 target compilation issues. - -* October 23, 2009 (Yang Tse) -- John Engelhart noticed an unreleased problem relative to a duplicate - ARES_ECANCELLED error code value and missing error code description. - -* October 7, 2009 (Yang Tse) -- Overhauled ares__get_hostent() Fixing out of bounds memory overwrite - triggered with malformed /etc/hosts file. Improving parsing of /etc/hosts - file. Validating requested address family. Ensuring that failures always - return a NULL pointer. Adjusting header inclusions. - -* October 6, 2009 (Yang Tse) -- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak. - -* September 29, 2009 (Yang Tse) -- Make configure script also check if _REENTRANT definition is required to - make errno available as a preprocessor macro. - -* September 7, 2009 (Yang Tse) -- Add T_SRV portability check to ares_parse_srv_reply.c - -* 4 Sep 2009 (Daniel Stenberg) -- Jakub Hrozek added ares_parse_srv_reply() for SRV parsing - -* 3 Aug 2009 (Daniel Stenberg) -- Joshua Kwan fixed the init routine to fill in the defaults for stuff that - fails to get inited by other means. This fixes a case of when the c-ares - init fails when internet access is fone. - -- Timo Teras changed the reason code used in the resolve callback done when - ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to - better allow the callback to know what's happening. - -* 14 Jul 2009 (Guenter Knauf) -- renamed generated config.h to ares_config.h to avoid any future clashes - with config.h from other projects. - -* June 20 2009 (Yang Tse) -- Refactor how libraries are checked for connect() function in configure - script and check for connect() as it is done for other functions. - -* June 19 2009 (Yang Tse) -- Make sclose() function-like macro definition used to close a socket, - now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL - config file preprocessor definitions - -* June 18 2009 (Yang Tse) -- Add CloseSocket camel case function check for configure script. - -* June 17 2009 (Yang Tse) -- Check for socket() and closesocket() as it is done for other functions - in configure script. - -* June 11 2009 (Yang Tse) -- Modified buildconf so that when automake runs it copies missing files - instead of symlinking them. - -* June 8 2009 (Yang Tse) -- Removed buildconf.bat from release and daily snapshot archives. This - file is only for CVS tree checkout builds. - -* May 26 2009 (Yang Tse) -- Added --enable-curldebug configure option to enable and disable building - with the low-level curl debug memory tracking 'feature' to allow decoupled - setting from --enable-debug, allowing again to build c-ares independently - out of the CVS tree. - - For the c-ares library option --enable-debug enables debug build features - which are _not_ related with memory tracking. For the c-ares library when - --enable-debug is given it does not enable the memory tracking feature. If - you wish to enable the curl debug memory tracking you must use configure - option --enable-curldebug explicitily to do so. - - Internally, definition of preprocessor symbol DEBUGBUILD restricts code - which is only compiled for debug enabled builds. And symbol CURLDEBUG is - used to differentiate code which is _only_ used for memory tracking. - - Make ares_init(), ares_dup() and ares_init_options() fail returning - ARES_ENOTINITIALIZED if library initialization has not been performed - calling ares_library_init(). - -* May 20 2009 (Yang Tse) -- Added ares_library_init() and ares_library_cleanup() man pages. - -* May 19 2009 (Yang Tse) -- Introduced ares_library_init() and ares_library_cleanup() functions. - - This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets - using c-ares 1.7.0 can still survive without calling these functions. Read all - the details on ares_library_init(3) and ares_library_cleanup(3) man pages that - are included. - - curl/libcurl 7.19.5 is fully compatible with c-ares 1.7.0 on all systems. - - In order to use c-ares 1.7.0 with curl/libcurl on Win32/64 systems it is - required that curl/libcurl is 7.19.5 or newer. In other words, it is not - possible on Win32/64 to use c-ares 1.7.0 with a curl/libcurl version less - than 7.19.5 - -* May 11 2009 (Daniel Stenberg) -- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to - only expose functions starting with ares_. - -* May 7 2009 (Yang Tse) -- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition - attempt in generated config.h - -* May 2 2009 (Yang Tse) -- Use a build-time configured ares_socklen_t data type instead of socklen_t. - -* April 21 2009 (Yang Tse) -- Moved potential inclusion of system's malloc.h and memory.h header files to - setup_once.h. Inclusion of each header file is based on the definition of - NEED_MALLOC_H and NEED_MEMORY_H respectively. - -* March 11 2009 (Yang Tse) -- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long. - -* February 20 2009 (Yang Tse) -- Do not halt compilation when using VS2008 to build a Windows 2000 target. - -* February 3 2009 (Phil Blundell) -- If the server returns garbage or nothing at all in response to an AAAA query, - go on and ask for A records anyway. - -* January 31 2009 (Daniel Stenberg) -- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving - either AF_INET6 or AF_INET. It works by accepting any of the looksups in the - hosts file, and it resolves the AAAA field with a fallback to A. - -* January 14 2009 (Daniel Stenberg) -- ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it - now declares the private struct ares_in6_addr for all systems instead of - relying on one possibly not present in the system. - -* January 13 2009 (Phil Blundell) -- ares__send_query() now varies the retry timeout pseudo-randomly to avoid - packet storms when several queries were started at the same time. - -* January 11 2009 (Daniel Stenberg) -- Phil Blundell added the internal function ares__expand_name_for_response() - that is now used by the ares_parse_*_reply() functions instead of the - ares_expand_name() simply to easier return ARES_EBADRESP for the cases where - the name expansion fails as in responses that really isn't expected. - -Version 1.6.0 (Dec 9, 2008) - -* December 9 2008 (Gisle Vanem) - - Fixes for Win32 targets using the Watt-32 tcp/ip stack. - -* Dec 4 2008 (Daniel Stenberg) - - Gregor Jasny provided the patch that introduces ares_set_socket_callback(), - and I edited it to also get duped by ares_dup(). - -* Dec 3 2008 (Daniel Stenberg) - - API changes: - - I made sure the public ares_config struct looks like before and yet it - supports the ROTATE option thanks to c-ares now storing the "optmask" - internally. Thus we should be ABI compatible with the past release(s) - now. My efforts mentioned below should not break backwards ABI compliance. - - Here's how I suggest we proceed with the API: - - ares_init() will be primary "channel creator" function. - - ares_init_options() will continue to work exactly like now and before. For - starters, it will be the (only) way to set the existing options. - - ares_save_options() will continue to work like today, but will ONLY save - options that you can set today (including ARES_OPT_ROTATE actually) but new - options that we add may not be saved with this. - - Instead we introduce: - - ares_dup() that instead can make a new channel and clone the config used - from an existing channel. It will then clone all config options, including - future new things we add. - - ares_set_*() style functions that set (new) config options. As a start we - simply add these for new functionality, but over time we can also introduce - them for existing "struct ares_options" so that we can eventually deprecate - the two ares_*_options() functions. - - ares_get_*() style functions for extracting info from a channel handle that - should be used instead of ares_save_options(). - -* Nov 26 2008 (Yang Tse) -- Brad Spencer provided changes to allow buildconf to work on OS X. - -- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a - buffer to shrink instead of expand if a reply contained 8 or more records. - -* Nov 25 2008 (Yang Tse) -- In preparation for the upcomming IPv6 nameservers patch, the internal - ares_addr union is now changed into an internal struct which also holds - the address family. - -* Nov 19 2008 (Daniel Stenberg) -- Brad Spencer brought the new function ares_gethostbyname_file() which simply - resolves a host name from the given file, using the regular hosts syntax. - -* Nov 1 2008 (Daniel Stenberg) -- Carlo Contavalli added support for the glibc "rotate" option, as documented - in man resolv.conf: - - causes round robin selection of nameservers from among those listed. This - has the effect of spreading the query load among all listed servers, rather - than having all clients try the first listed server first every time. - - You can enable it with ARES_OPT_ROTATE - -* Oct 21 2008 (Yang Tse) - Charles Hardin added handling of EINPROGRESS for UDP connects. - -* Oct 18 2008 (Daniel Stenberg) - Charles Hardin made adig support a regular numerical dotted IP address for the - -s option as well. - -* Oct 7 2008 (Yang Tse) -- Added --enable-optimize configure option to enable and disable compiler - optimizations to allow decoupled setting from --enable-debug. - -* Oct 2 2008 (Yang Tse) -- Added --enable-warnings configure option to enable and disable strict - compiler warnings to allow decoupled setting from --enable-debug. - -* Sep 17 2008 (Yang Tse) -- Code reorganization to allow internal/private use of "nameser.h" to any - system that lacks arpa/nameser.h or arpa/nameser_compat.h header files. - -* Sep 16 2008 (Yang Tse) -- Code reorganization to allow internal/private use of ares_writev to any - system that lacks the writev function. - -* Sep 15 2008 (Yang Tse) -- Code reorganization to allow internal/private use of ares_strcasecmp to any - system that lacks the strcasecmp function. - -- Improve configure detection of some string functions. - -* Sep 11 2008 (Yang Tse) -- Code reorganization to allow internal/private use of ares_strdup to any - system that lacks the strdup function. - -Version 1.5.3 (Aug 29, 2008) - -* Aug 25 2008 (Yang Tse) -- Improvement by Brad House: - - This patch addresses an issue in which a response could be sent back to the - source port of a client from a different address than the request was made to. - This is one form of a DNS cache poisoning attack. - - The patch simply uses recvfrom() rather than recv() and validates that the - address returned from recvfrom() matches the address of the server we have - connected to. Only necessary on UDP sockets as they are connection-less, TCP - is unaffected. - -- Fix by George Neill: - Fixed compilation of acountry sample application failure on some systems. - -* Aug 4 2008 (Daniel Stenberg) -- Fix by Tofu Linden: - - The symptom: - * Users (usually, but not always) on 2-Wire routers and the Comcast service - and a wired connection to their router would find that the second and - subsequent DNS lookups from fresh processes using c-ares to resolve the same - address would cause the process to never see a reply (it keeps polling for - around 1m15s before giving up). - - The repro: - * On such a machine (and yeah, it took us a lot of QA to find the systems - that reproduce such a specific problem!), do 'ahost www.secondlife.com', - then do it again. The first process's lookup will work, subsequent lookups - will time-out and fail. - - The cause: - * init_id_key() was calling randomize_key() *before* it initialized - key->state, meaning that the randomness generated by randomize_key() is - immediately overwritten with deterministic values. (/dev/urandom was also - being read incorrectly in the c-ares version we were using, but this was - fixed in a later version.) - * This makes the stream of generated query-IDs from any new c-ares process - be an identical and predictable sequence of IDs. - * This makes the 2-Wire's default built-in DNS server detect these queries - as probable-duplicates and (erroneously) not respond at all. - - -* Aug 4 2008 (Yang Tse) -- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use. - Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62 - version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols - no matter if the system is AIX or not. To keep the traditional behaviour, - and an uniform one across autoconf versions AC_AIX is replaced with our - own internal macro CARES_CHECK_AIX_ALL_SOURCE. - -* Aug 1 2008 (Yang Tse) -- Configure process now checks if the preprocessor _REENTRANT symbol is already - defined. If it isn't currently defined a set of checks are performed to test - if its definition is required to make visible to the compiler a set of *_r - functions. Finally, if _REENTRANT is already defined or needed it takes care - of making adjustments necessary to ensure that it is defined equally for the - configure process tests and generated config file. - -* Jul 20 2008 (Yang Tse) -- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will - now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID, - RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID. - -* Jul 17 2008 (Yang Tse) -- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined - to the data type pointed by its respective argument and not the pointer type. - -* Jul 16 2008 (Yang Tse) -- Improved configure detection of number of arguments for getservbyport_r. - Detection is now based on compilation checks instead of linker ones. - -- Configure process now checks availability of recvfrom() socket function and - finds out its return type and the types of its arguments. Added definitions - for non-configure systems config files, and introduced macro sreadfrom which - will be used on udp sockets as a recvfrom() wrapper in the future. - -* Jul 15 2008 (Yang Tse) -- Introduce definition of _REENTRANT symbol in setup.h to improve library - usability. Previously the configure process only used the AC_SYS_LARGEFILE - macro for debug builds, now it is also used for non-debug ones enabling the - use of configure options --enable-largefile and --disable-largefile which - might be needed for library compatibility. Remove checking the size of - curl_off_t, it is no longer needed. - -* Jul 3 2008 (Daniel Stenberg) -- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and - the target host has only A records, it automatically falls back to an - AF_INET lookup and gives you the A results. However, if the target host has - a CNAME record, this behaviour is defeated since the original query does - return some data even though ares_parse_aaa_reply() doesn't consider it - relevant. Here's a small patch to make it behave the same with and without - the CNAME. - -* Jul 2 2008 (Yang Tse) -- Fallback to gettimeofday when monotonic clock is unavailable at run-time. - -* Jun 30 2008 (Daniel Stenberg) - -- As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is - not posix or anything and thus c-ares failed to build on hurd (and possibly - elsewhere). The define was also somewhat artificially used in the windows - port. Now, I instead rewrote the use of gethostbyname to enlarge the host - name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN - define. I thus also removed the defien from the namser.h file where it was - once added for the windows build. - - I also fixed init_by_defaults() function to not leak memory in case if - error. - -* Jun 9 2008 (Yang Tse) - -- Make libcares.pc generated file for pkg-config include information relative - to the libraries needed for the static linking of c-ares. - -* May 30 2008 (Yang Tse) - -- Brad House fixed a missing header file inclusion in adig sample program. - -Version 1.5.2 (May 29, 2008) - -* May 13 2008 (Daniel Stenberg) - -- Introducing millisecond resolution support for the timeout option. See - ares_init_options()'s ARES_OPT_TIMEOUTMS. - -* May 9 2008 (Yang Tse) - -- Use monotonic time source if available, for private function ares__tvnow() - -* May 7 2008 (Daniel Stenberg) - -- Sebastian made c-ares able to return all PTR-records when doing reverse - lookups. It is not common practice to have multiple PTR-Records for a single - IP, but its perfectly legal and some sites have those. - -- Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to - autoconf 2.57 usage (which is the version you have specified as the minimum - version). It's a minor change but it does clean up some warnings with newer - autoconf (specifically 2.62). - -* May 5 2008 (Yang Tse) - -- Improved parsing of resolver configuration files. - -* April 4 2008 (Daniel Stenberg) - -- Eino Tuominen improved the code when a file is used to seed the randomizer. - -- Alexey Simak made adig support NAPTR records - -- Alexey Simak fixed the VC dsp file by adding the missing source file - ares_expand_string.c - -* December 11 2007 (Gisle Vanem) - -- Added another sample application; acountry.c which converts an - IPv4-address(es) and/or host-name(s) to country-name and country-code. - This uses the service of the DNSBL at countries.nerd.dk. - -* December 3 2007 (Daniel Stenberg) - -- Brad Spencer fixed the configure script to assume that there's no - /dev/urandom when built cross-compiled as then the script cannot check for - it. - -- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat - -Version 1.5.1 (Nov 21, 2007) - -* November 21 2007 (Daniel Stenberg) - -- Robin Cornelius pointed out that ares_llist.h was missing in the release - archive for 1.5.0 - -Version 1.5.0 (Nov 21, 2007) - -* October 2 2007 (Daniel Stenberg) - -- ares_strerror() segfaulted if the input error number was out of the currently - supported range. - -- Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in - internal function init_id_key() under low memory conditions. - -* September 28 2007 (Daniel Stenberg) - -- Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI - and API changes in the progress callback (and possibly more coming up from - Steinar) - -* September 28 2007 (Steinar H. Gunderson) - -- Don't skip a server if it's the only one. (Bugfix from the Google tree.) - -- Made the query callbacks receive the number of timeouts that happened during - the execution of a query, and updated documentation accordingly. (Patch from - the Google tree.) - -- Support a few more socket options: ARES_OPT_SOCK_SNDBUF and - ARES_OPT_SOCK_RCVBUF - -- Always register for TCP events even if there are no outstanding queries, as - the other side could always close the connection, which is a valid event - which should be responded to. - -* September 22 2007 (Daniel Stenberg) - -- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in - several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that - if it fails and the socket is closed the following code doesn't try to use - the file descriptor. - -- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when - TCP is used since there are several edge cases where it still makes sense. - -- Brad House provided a fix for ares_save_options(): - - Apparently I overlooked something with the ares_save_options() where it - would try to do a malloc(0) when no options of that type needed to be saved. - On most platforms, this was fine because malloc(0) doesn't actually return - NULL, but on AIX it does, so ares_save_options would return ARES_ENOMEM. - -* July 14 2007 (Daniel Stenberg) - -- Vlad Dinulescu fixed two outstanding valgrind reports: - - 1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short - int variable) with qid, which is declared as an int variable. Moreover, - DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID - sets only the first two bytes of qid. I think that qid should be declared as - "unsigned short" in this function. - - 2. The same problem occurs in ares_process.c, process_answer() . query->qid - (an unsigned short integer variable) is compared with id, which is an - integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets - only the first two bytes of id. I think that the id variable should be - declared as "unsigned short" in this function. - - Even after declaring these variables as "unsigned short", the valgrind - errors are still there. Which brings us to the third problem. - - 3. The third problem is that Valgrind assumes that query->qid is not - initialised correctly. And it does that because query->qid is set from - DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And - qbuf has uninitialised bytes because of channel->next_id . And next_id is - set by ares_init.c:ares__generate_new_id() . I found that putting short r=0 - in this function (instead of short r) makes all Valgrind warnings go away. - I have studied ares__rc4() too, and this is the offending line: - - buffer_ptr[counter] ^= state[xorIndex]; (ares_query.c:62) - - This is what triggers Valgrind.. buffer_ptr is unitialised in this function, - and by applying ^= on it, it remains unitialised. - -Version 1.4.0 (June 8, 2007) - -* June 4 2007 (Daniel Stenberg) - -- James Bursa reported a major memory problem when resolving multi-IP names - and I found and fixed the problem. It was added by Ashish Sharma's patch - two days ago. - - When I then tried to verify multiple entries in /etc/hosts after my fix, I - got another segfault and decided this code was not ripe for inclusion and I - reverted the patch. - -* June 2 2007 - -- Brad Spencer found and fixed three flaws in the code, found with the new - gcc 4.2.0 warning: -Waddress - -- Brad House fixed VS2005 compiler warnings due to time_t being 64bit. - He also made recent Microsoft compilers use _strdup() instead of strdup(). - -- Brad House's man pages for ares_save_options() and ares_destroy_options() - were added. - -- Ashish Sharma provided a patch for supporting multiple entries in the - /etc/hosts file. Patch edited for coding style and functionality by me - (Daniel). - -* May 30 2007 - -- Shmulik Regev brought cryptographically secure transaction IDs: - - The c-ares library implementation uses a DNS "Transaction ID" field that is - seeded with a pseudo random number (based on gettimeofday) which is - incremented (++) between consecutive calls and is therefore rather - predictable. In general, predictability of DNS Transaction ID is a well - known security problem (e.g. - http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based - implementation vulnerable to DNS poisoning. Credit goes to Amit Klein - (Trusteer) for identifying this problem. - - The patch I wrote changes the implementation to use a more secure way of - generating unique IDs. It starts by obtaining a key with reasonable entropy - which is used with an RC4 stream to generate the cryptographically secure - transaction IDs. - - Note that the key generation code (in ares_init:randomize_key) has two - versions, the Windows specific one uses a cryptographically safe function - provided (but undocumented :) by the operating system (described at - http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx). The - default implementation is a bit naive and uses the standard 'rand' - function. Surely a better way to generate random keys exists for other - platforms. - - The patch can be tested by using the adig utility and using the '-s' option. - -- Brad House added ares_save_options() and ares_destroy_options() that can be - used to keep options for later re-usal when ares_init_options() is used. - - Problem: Calling ares_init() for each lookup can be unnecessarily resource - intensive. On windows, it must LoadLibrary() or search the registry - on each call to ares_init(). On unix, it must read and parse - multiple files to obtain the necessary configuration information. In - a single-threaded environment, it would make sense to only - ares_init() once, but in a heavily multi-threaded environment, it is - undesirable to ares_init() and ares_destroy() for each thread created - and track that. - - Solution: Create ares_save_options() and ares_destroy_options() functions to - retrieve and free options obtained from an initialized channel. The - options populated can be used to pass back into ares_init_options(), - it should populate all needed fields and not retrieve any information - from the system. Probably wise to destroy the cache every minute or - so to prevent the data from becoming stale. - -- Daniel S added ares_process_fd() to allow applications to ask for processing - on specific sockets and thus avoiding select() and associated - functions/macros. This function will be used by upcoming libcurl releases - for this very reason. It also made me export the ares_socket_t type in the - public ares.h header file, since ares_process_fd() uses that type for two of - the arguments. - -* May 25 2007 - -- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows - that could cause it to return a bad return code. - -* April 16 2007 - -- Yang Tse: Provide ares_getopt() command-line parser function as a source - code helper function, not belonging to the actual c-ares library. - -* February 19 2007 - -- Vlad Dinulescu added ares_parse_ns_reply(). - -* February 13 2007 - -- Yang Tse: Fix failure to get the search sequence of /etc/hosts and - DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when - /etc/resolv.conf did not exist or was unable to read it. - -* November 22 2006 - -- Install ares_dns.h too - -- Michael Wallner fixed this problem: When I set domains in the options - struct, and there are domain/search entries in /etc/resolv.conf, the domains - of the options struct will be overridden. - -* November 6 2006 - -- Yang Tse removed a couple of potential zero size memory allocations. - -- Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel) - broke in the 1.3.2 release. We should switch to a system where that file is - auto-generated. We could rip some code for that from curl... - -Version 1.3.2 (November 3, 2006) - -* October 12 2006 - -- Prevent ares_getsock() to overflow if more than 16 sockets are used. - -* September 11 2006 - -- Guilherme Balena Versiani: I noted a strange BUG in Win32 port - (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network - by hand or disconnect the network cable in Windows 2000 or Windows XP, my - application gets 127.0.0.1 as the only name server. The problem comes from - 'GetNetworkParams' function, that returns the empty string "" as the only - name server in that case. Moreover, the Windows implementation of - inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE. - -* August 29 2006 - -- Brad Spencer did - - o made ares_version.h use extern "C" for c++ compilers - o fixed compiler warnings in ares_getnameinfo.c - o fixed a buffer position init for TCP reads - -* August 3 2006 - -- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and - not always zero! - -Version 1.3.1 (June 24, 2006) - -* July 23, 2006 - -- Gisle Vanem added getopt() to the ahost program. Currently accepts - only [-t {a|aaaa}] to specify address family in ares_gethostbyname(). - -* June 19, 2006 - -- (wahern) Removed "big endian" DNS section and RR data integer parser - macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise - operations in C operate on logical values. And in any event the octets are - already in big-endian (aka network) byte order so they're being reversed - (thus the source of the breakage). - -* June 18, 2006 - -- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls - from area_process.c. - - TODO: Handle one last EAGAIN for a UDP socket send(2) in - ares__send_query(). - -* May 10, 2006 - -- Bram Matthys brought my attention to a libtool peculiarity where detecting - things such as C++ compiler actually is a bad thing and since we don't need - that detection I added a work-around, much inspired by a previous patch by - Paolo Bonzini. This also shortens the configure script quite a lot. - -* May 3, 2006 - -- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes - c-ares call a callback on socket state changes. A better way than the - ares_getsock() to get full control over the socket state. - -* January 9, 2006 - -- Alexander Lazic improved the getservbyport_r() configure check. - -* January 6, 2006 - -- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS - variable for easier controlling what it does and how it runs. - -* January 5, 2006 - -- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it - build with newer gcc versions that no longer defines "riscos". - -* December 22 - -- Daniel Stenberg added ares_getsock() that extracts the set of sockets to - wait for action on. Similar to ares_fds() but not restricted to using - select() for the waiting. - -* November 25 - -- Yang Tse fixed some send() / recv() compiler warnings - -* September 18 - -- Added constants that will be used by ares_getaddrinfo - -- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it - is available to ensure it works properly in a threaded environment. - -* September 10 - -- configure fix for detecting a member in the sockaddr_in6 struct which failed - on ipv6-enabled HP-UX 11.00 - -Version 1.3.0 (August 29, 2005) - -* August 21 - -- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info() - when getting the DNS server etc. - -* June 19 - -- Added some checks for the addrinfo structure. - -* June 2 - -- William Ahern: - - Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a - read event can come back from poll() on a valid SOCK_DGRAM socket but - recv(2) will still block. This patch doesn't ignore EAGAIN in - read_udp_packets(), though maybe it should. (This patch was edited by Daniel - Stenberg and a new configure test was added (imported from curl's configure) - to properly detect what non-blocking socket approach to use.) - - I'm not quite sure how this was happening, but I've been seeing PTR queries - which seem to return empty responses. At least, they were empty when calling - ares_expand_name() on the record. Here's a patch which guarantees to - NUL-terminate the expanded name. The old behavior failed to NUL-terminate if - len was 0, and this was causing strlen() to run past the end of the buffer - after calling ares_expand_name() and getting ARES_SUCCESS as the return - value. If q is not greater than *s then it's equal and *s is always - allocated with at least one byte. - -* May 16 - -- Added ares_getnameinfo which mimics the getnameinfo API (another feature - that could use testing). - -* May 14 - -- Added an inet_ntop function from BIND for systems that do not have it. - -* April 9 - -- Made sortlist support IPv6 (this can probably use some testing). - -- Made sortlist support CIDR matching for IPv4. - -* April 8 - -- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist - does not work with IPv6. Also provided an implementation of bitncmp from - BIND for systems that do not supply this function. This will be used to add - IPv6 support to sortlist. - -- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family. - The function can lookup IPv6 addresses both from files (/etc/hosts) and - DNS lookups. - -* April 7 - -- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac - OS X. - -* April 5 - -- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton - from BIND for systems that do not include these functions. - -* March 11, 2005 - -- Dominick Meglio added ares_parse_aaaa_reply.c and did various - adjustments. The first little steps towards IPv6 support! - -* November 7 - -- Fixed the VC project and makefile to use ares_cancel and ares_version - -* October 24 - -- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw. - This is now fixed. - -Version 1.2.1 (October 20, 2004) - -* September 29 - -- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital - when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for - other OSes. He made c-ares check for and understand it if present. - -- Now c-ares will use local host name lookup _before_ DNS resolving by default - if nothing else is told. - -* September 26 - -- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf - file to determine the sequence in which to search /etc/hosts and DNS. So on - systems where this order is defined by /etc/host.conf instead of a "lookup" - entry in /etc/resolv.conf, c-ares will always default to looking in DNS - first, and /etc/hosts second. - - c-ares now looks at - - 1) resolv.conf (for the "lookup" line); - 2) nsswitch.fon (for the "hosts:" line); - 3) host.conf (for the "order" line). - - First match wins. - -- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is - located in a static location. It assumed - C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact, - the location of the HOSTS file can be changed via a registry setting. - - There is a key called DatabasePath which specifies the path to the HOSTS - file: - http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx - - The patch will make c-ares correctly consult the registry for the location - of this file. - -* August 29 - -- Gisle Vanem fixed the MSVC build files. - -* August 20 - -- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack. - -* August 13 - -- Harshal Pradhan made a minor syntax change in ares_init.c to make it build - fine with MSVC 7.1 - -* July 24 - -- Made the lib get built static only if --enable-debug is used. - -- Gisle Vanem fixed: - - Basically in loops like handle_errors(), 'query->next' was assigned a local - variable and then query was referenced after the memory was freed by - next_server(). I've changed that so next_server() and end_query() returns - the next query. So callers should use this ret-value. - - The next problem was that 'server->tcp_buffer_pos' had a random value at - entry to 1st recv() (luckily causing Winsock to return ENOBUFS). - - I've also added a ares_writev() for Windows to streamline the code a bit - more. - -* July 20 -- Fixed a few variable return types for some system calls. Made configure - check for ssize_t to make it possible to use that when receiving the send() - error code. This is necessary to prevent compiler warnings on some systems. - -- Made configure create config.h, and all source files now include setup.h that - might include the proper config.h (or a handicrafted alternative). - -- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't - use 'int' for that. - -- automake-ified and libool-ified c-ares. Now it builds libcares as a shared - lib on most platforms if wanted. (This bloated the size of the release - archive with another 200K!) - -- Makefile.am now uses Makefile.inc for the c sources, h headers and man - pages, to make it easier for other makefiles to use the exact same set of - files. - -- Adjusted 'maketgz' to use the new automake magic when building distribution - archives. - -- Anyone desires HTML and/or PDF versions of the man pages in the release - archives? - -* July 3 -- Günter Knauf made c-ares build and run on Novell Netware. - -* July 1 -- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp - fixes and made ares not use 'errno' to provide further info on Windows. - -* June 30 -- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack. - -* June 10 -- Gisle Vanem's init patch for Windows: - - The init_by_resolv_conf() function fetches the DNS-server(s) - from a series of registry branches. - - This can be wrong in the case where DHCP has assigned nameservers, but the - user has overridden these servers with other prefered settings. Then it's - wrong to use the DHCPNAMESERVER setting in registry. - - In the case of no global DHCP-assigned or fixed servers, but DNS server(s) - per adapter, one has to query the adapter branches. But how can c-ares know - which adapter is valid for use? AFAICS it can't. There could be one adapter - that is down (e.g. a VPN adapter). - - So it's better to leave this to the IP Helper API (iphlapi) available in - Win-98/2000 and later. My patch falls-back to the old way if not available. - -* June 8 -- James Bursa fixed an init issue for RISC OS. - -* May 11 -- Nico Stappenbelt reported that when processing domain and search lines in - the resolv.conf file, the first entry encountered is processed and used as - the search list. According to the manual pages for both Linux, Solaris and - Tru64, the last entry of either a domain or a search field is used. - - This is now adjusted in the code - -Version 1.2.0 (April 13, 2004) - -* April 2, 2004 -- Updated various man pages to look nicer when converted to HTML on the web - site. - -* April 1, 2004 -- Dirk Manske provided a new function that is now named ares_cancel(). It is - used to cancel/cleanup a resolve/request made using ares functions on the - given ares channel. It does not destroy/kill the ares channel itself. - -- Dominick Meglio cleaned up the formatting in several man pages. - -* March 30, 2004 -- Dominick Meglio's new ares_expand_string. A helper function when decoding - incoming DNS packages. - -- Daniel Stenberg modified the Makefile.in to use a for loop for the man page - installation to improve overview and make it easier to add man pages. - -Version 1.1.0 (March 11, 2004) - -* March 9, 2004 -- Gisle Vanem improved build on Windows. - -* February 25, 2004 -- Dan Fandrich found a flaw in the Feb 22 fix. - -- Added better configure --enable-debug logic (taken from the curl configure - script). Added acinclude.m4 to the tarball. - -* February 23, 2004 -- Removed ares_free_errmem(), the function, the file and the man page. It was - not used and it did nothing. - -- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of - compiler warnings on picky compilers. - -* February 22, 2004 -- Dominick Meglio made ares init support multiple name servers in the - NameServer key on Windows. - -* February 16, 2004 -- Modified ares_private.h to include libcurl's memory debug header if - CURLDEBUG is set. This makes all the ares-functions supervised properly by - the curl test suite. This also forced me to add inclusion of the - ares_private.h header in a few more files that are using some kind of - memory-related resources. - -- Made the makefile only build ahost and adig if 'make demos' is used. - -* February 10, 2004 -- Dirk Manske made ares_version.h installed with 'make install' - -* February 4, 2004 -- ares_free_errmem() is subject for removal, it is simply present for future - purposes, and since we removed the extra parameter in strerror() it won't - be used by c-ares! -- configure --enable-debug now enables picky compiler options if gcc is used -- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk - reported - -Version 1.0.0 (February 3, 2004) - -* February 3, 2004 -- now we produce the libcares.a library instead of the previous libares.a - since we are no longer compatible - -* February 2, 2004 - -- ares_strerror() has one argument less. This is the first official - modification of the existing provided ares API. - -* January 29, 2004 - -- Dirk Manske fixed how the socket is set non-blocking. - -* January 4, 2004 - -- Dominick Meglio made the private gettimeofday() become ares_gettimeofday() - instead in order to not pollute the name space and risk colliding with - other libraries' versions of this function. - -* October 24, 2003.

It is intended for -applications which need to perform DNS queries without blocking, or -need to perform multiple DNS queries in parallel. The primary -examples of such applications are servers which communicate with -multiple clients and programs with graphical user interfaces. - -This library implementation is not especially portable to crufty old -systems like SunOS 4. It assumes a compiler which can handle ANSI C -syntax, a system malloc which properly handles realloc(NULL, foo) and -free(NULL), and a reasonably up-to-date <arpa/nameser.h>. - -I have attempted to preserve the externally visible behavior of the -BIND resolver in nearly all respects. The API of the library is, of -course, very different from the synchronous BIND API; instead of -invoking a function like res_send() and getting a return value back -indicating the number of bytes in the response, you invoke a function -like ares_send() and give it a callback function to invoke when the -response arrives. You then have to select() on the file descriptors -indicated by ares_fds(), with a timeout given by ares_timeout(). You -call ares_process() when select() returns. - -Some features are missing from the current version of ares, relative -to the BIND resolver: - - * There is no IPV6 support. [not true for c-ares] - * There is no hostname verification. - * There is no logging of unexpected events. - * There is no debugging-oriented logging. - * There is no YP support. - -libares requires an ANSI compiler to compile and use. To build the -library, just run "./configure" and "make". To install it, run "make -install". Run "./configure --help" to see a list of options you can -provide to configure to change how the library builds. libares has no -data files, so you can move the include file and library around freely -without leaving behind any dependencies on old paths. Building the -library will also build the "adig" program, a little toy for trying -out the library. It doesn't get installed. - -libares is distributed at athena-dist.mit.edu:pub/ATHENA/ares.

If it returns successfully, \fBares_init\fP will set the -variable pointed to by \fIchannelptr\fP to a handle used to identify the name -service channel. The caller should invoke -.BR ares_destroy (3) -on the handle when the channel is no longer needed. -.PP -The \fBares_init_options\fP function also initializes a name service channel, -with additional options useful for applications requiring more control over -name service configuration. The \fIoptmask\fP parameter specifies which fields -in the structure pointed to by \fIoptions\fP are set, as follows: -.TP 18 -.B ARES_OPT_FLAGS -.B int \fIflags\fP; -.br -Flags controlling the behavior of the resolver. See below for a -description of possible flag values. -.TP 18 -.B ARES_OPT_TIMEOUT -.B int \fItimeout\fP; -.br -The number of seconds each name server is given to respond to a query on the -first try. (After the first try, the timeout algorithm becomes more -complicated, but scales linearly with the value of \fItimeout\fP.) The -default is five seconds. This option is being deprecated by -\fIARES_OPT_TIMEOUTMS\fP starting in c-ares 1.5.2. -.TP 18 -.B ARES_OPT_TIMEOUTMS -.B int \fItimeout\fP; -.br -The number of milliseconds each name server is given to respond to a query on -the first try. (After the first try, the timeout algorithm becomes more -complicated, but scales linearly with the value of \fItimeout\fP.) The -default is five seconds. Note that this option is specified with the same -struct field as the former \fIARES_OPT_TIMEOUT\fP, it is but the option bits -that tell c-ares how to interpret the number. This option was added in c-ares -1.5.2. -.TP 18 -.B ARES_OPT_TRIES -.B int \fItries\fP; -.br -The number of tries the resolver will try contacting each name server -before giving up. The default is four tries. -.TP 18 -.B ARES_OPT_NDOTS -.B int \fIndots\fP; -.br -The number of dots which must be present in a domain name for it to be -queried for "as is" prior to querying for it with the default domain -extensions appended. The default value is 1 unless set otherwise by -resolv.conf or the RES_OPTIONS environment variable. -.TP 18 -.B ARES_OPT_PORT -.B unsigned short \fIport\fP; -.br -The port to use for queries (both TCP and UDP), in network byte order. -The default value is 53 (in network byte order), the standard name -service port. -.TP 18 -.B ARES_OPT_SERVERS -.B struct in_addr *\fIservers\fP; -.br -.B int \fInservers\fP; -.br -The list of IPv4 servers to contact, instead of the servers specified in -resolv.conf or the local named. In order to allow specification of either -IPv4 or IPv6 name servers, function -.BR ares_set_servers(3) -must be used instead. -.TP 18 -.B ARES_OPT_DOMAINS -.B char **\fIdomains\fP; -.br -.B int \fIndomains\fP; -.br -The domains to search, instead of the domains specified in resolv.conf -or the domain derived from the kernel hostname variable. -.TP 18 -.B ARES_OPT_LOOKUPS -.B char *\fIlookups\fP; -.br -The lookups to perform for host queries. -.I lookups -should be set to a string of the characters "b" or "f", where "b" -indicates a DNS lookup and "f" indicates a lookup in the hosts file. -.TP 18 -.B ARES_OPT_SOCK_STATE_CB -.B void (*\fIsock_state_cb\fP)(void *data, int s, int read, int write); -.br -.B void *\fIsock_state_cb_data\fP; -.br -A callback function to be invoked when a socket changes state. -.I s -will be passed the socket whose state has changed; -.I read -will be set to true if the socket should listen for read events, and -.I write -will be set to true if the socket should listen for write events. -The value of -.I sock_state_cb_data -will be passed as the -.I data -argument. -.PP -The -.I flags -field should be the bitwise or of some subset of the following values: -.TP 23 -.B ARES_FLAG_USEVC -Always use TCP queries (the "virtual circuit") instead of UDP -queries. Normally, TCP is only used if a UDP query yields a truncated -result. -.TP 23 -.B ARES_FLAG_PRIMARY -Only query the first server in the list of servers to query. -.TP 23 -.B ARES_FLAG_IGNTC -If a truncated response to a UDP query is received, do not fall back -to TCP; simply continue on with the truncated response. -.TP 23 -.B ARES_FLAG_NORECURSE -Do not set the "recursion desired" bit on outgoing queries, so that the name -server being contacted will not try to fetch the answer from other servers if -it doesn't know the answer locally. Be aware that ares will not do the -recursion for you. Recursion must be handled by the application calling ares -if \fIARES_FLAG_NORECURSE\fP is set. -.TP 23 -.B ARES_FLAG_STAYOPEN -Do not close communications sockets when the number of active queries -drops to zero. -.TP 23 -.B ARES_FLAG_NOSEARCH -Do not use the default search domains; only query hostnames as-is or -as aliases. -.TP 23 -.B ARES_FLAG_NOALIASES -Do not honor the HOSTALIASES environment variable, which normally -specifies a file of hostname translations. -.TP 23 -.B ARES_FLAG_NOCHECKRESP -Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED -response code or responses whose questions don't match the questions -in the request. Primarily useful for writing clients which might be -used to test or debug name servers. -.SH RETURN VALUES -.I ares_init -or -.I ares_init_options -can return any of the following values: -.TP 14 -.B ARES_SUCCESS -Initialization succeeded. -.TP 14 -.B ARES_EFILE -A configuration file could not be read. -.TP 14 -.B ARES_ENOMEM -The process's available memory was exhausted. -.TP 14 -.B ARES_ENOTINITIALIZED -c-ares library initialization not yet performed. -.SH SEE ALSO -.BR ares_destroy(3), -.BR ares_dup(3), -.BR ares_library_init(3), -.BR ares_set_servers(3) -.SH AUTHOR -Greg Hudson, MIT Information Systems -.br -Copyright 1998 by the Massachusetts Institute of Technology. -.br -Copyright (C) 2004-2010 by Daniel Stenberg. diff --git a/ares/ares_init.c b/ares/ares_init.c deleted file mode 100644 index 0a481e156..000000000 --- a/ares/ares_init.c +++ /dev/null @@ -1,1627 +0,0 @@ -/* $Id$ */ - -/* Copyright 1998 by the Massachusetts Institute of Technology. - * Copyright (C) 2007-2010 by Daniel Stenberg - * - * Permission to use, copy, modify, and distribute this - * software and its documentation for any purpose and without - * fee is hereby granted, provided that the above copyright - * notice appear in all copies and that both that copyright - * notice and this permission notice appear in supporting - * documentation, and that the name of M.I.T. not be used in - * advertising or publicity pertaining to distribution of the - * software without specific, written prior permission. - * M.I.T. makes no representations about the suitability of - * this software for any purpose.
