 This release includes the following changes:
+

   Changelog for the c-ares project
 
+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)

+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.

+
+ It can also be noted that to do this properly in an automated fashion, you
+ will most certainly need to script things and do multiple curl invokes etc.
+
+ First, servers mostly use cookies to track the logged-in status of the
+ client, so you will need to capture the cookies you receive in the
+ responses. Then, many sites also set a special cookie on the login page (to
+ make sure you got there through their login page) so you should make a habit
+ of first getting the login-form page to capture the cookies set there.
+
+ Some web-based login systems features various amounts of javascript, and
+ sometimes they use such code to set or modify cookie contents. Possibly they
+ do that to prevent programmed logins, like this manual describes how to...
+ Anyway, if reading the code isn't enough to let you repeat the behavior
+ manually, capturing the HTTP requests done by your browers and analyzing the
+ sent cookies is usually a working method to work out how to shortcut the
+ javascript need.
+
+ In the actual <form> tag for the login, lots of sites fill-in random/session
+ or otherwise secretly generated hidden tags and you may need to first capture
+ the HTML code for the login form and extract all the hidden fields to be able
+ to do a proper login POST. Remember that the contents need to be URL encoded
