                                  Changelog

Daniel (5 April 2006)
- Michele Bini modified the NTLM code to work for his "weird IIS case"
  (http://curl.haxx.se/mail/lib-2006-02/0154.html) by adding the NTLM hash
  function in addition to the LM one and making some other adjustments in the
  order the different parts of the data block are sent in the Type-2 reply.
  Inspiration for this work was taken from the Firefox NTLM implementation.

  I edited the existing 21(!) NTLM test cases to run fine with these news. Due
  to the fact that we now properly include the host name in the Type-2 message
  the test cases now only compare parts of that chunk.

Daniel (28 March 2006)
- #1451929 (http://curl.haxx.se/bug/view.cgi?id=1451929) detailed a bug that
  occurred when asking libcurl to follow HTTP redirects and the original URL
  had more than one question mark (?). Added test case 276 to verify.

Daniel (27 March 2006)
- David Byron found a problem multiple -d options when libcurl was built with
  --enable-debug, as then curl used free() on memory allocated both with
  normal malloc() and with libcurl-provided functions, when the latter MUST be
  freed with curl_free() in debug builds.

Daniel (26 March 2006)
- Tor Arntsen figured out that TFTP was broken on a lot of systems since we
  called bind() with a too big argument in the 3rd parameter and at least
  Tru64, AIX and IRIX seem to be very picky about it.

Daniel (21 March 2006)
- David McCreedy added CURLINFO_FTP_ENTRY_PATH.

- Xavier Bouchoux made the SSL connection non-blocking for the multi interface
  (when using OpenSSL).

- Tor Arntsen fixed the AIX Toolbox RPM spec

Daniel (20 March 2006)
- David McCreedy fixed libcurl to no longer ignore AUTH failures and now it
  reacts properly according to the CURLOPT_FTP_SSL setting.

- Dan Fandrich fixed two TFTP problems: Fixed a bug whereby a received file
  whose length was a multiple of 512 bytes could have random garbage
  appended. Also, stop processing TFTP packets which are too short to be
  legal.

- Ilja van Sprundel reported a possible crash in the curl tool when using
  "curl hostwithoutslash -d data -G"

Version 7.15.3 (20 March 2006)

Daniel (20 March 2006)
- VULNERABILITY reported to us by Ulf Harnhammar.

  libcurl uses the given file part of a TFTP URL in a manner that allows a
  malicious user to overflow a heap-based memory buffer due to the lack of
  boundary check.

  This overflow happens if you pass in a URL with a TFTP protocol prefix
  ("tftp://"), using a valid host and a path part that is longer than 512
  bytes.

  The affected flaw can be triggered by a redirect, if curl/libcurl is told to
  follow redirects and an HTTP server points the client to a tftp URL with the
  characteristics described above.

  The Common Vulnerabilities and Exposures (CVE) project has assigned the name
  CVE-2006-1061 to this issue.

Daniel (16 March 2006)
- Tor Arntsen provided a RPM spec file for AIX Toolbox, that now is included
  in the release archive.

Daniel (14 March 2006)
- David McCreedy fixed:

  a bad SSL error message when OpenSSL certificates are verified fine.

  a missing return code assignment in the FTP code

Daniel (7 March 2006)
- Markus Koetter filed debian bug report #355715 which identified a problem
  with the multi interface and multi-part formposts. The fix from February
  22nd could make the Curl_done() function get called twice on the same
  connection and it was not designed for that and thus tried to call free() on
  an already freed memory area!

- Peter Heuchert made sure the CURLFTPSSL_CONTROL setting for CURLOPT_FTP_SSL
  is used properly.

Daniel (6 March 2006)
- Lots of users on Windows have reported getting the "SSL: couldn't set
  callback" error message so I've now made the setting of that callback not be
  as critical as before. The function is only used for additional loggging/
  trace anyway so a failure just means slightly less data. It should still be
  able to proceed and connect fine to the server.

Daniel (4 March 2006)
- Thomas Klausner provided a patch written by Todd Vierling in bug report
  #1442471 that fixes a build problem on Interix.

Daniel (2 March 2006)
- FTP upload without a file name part in the URL now causes
  curl_easy_perform() to return CURLE_URL_MALFORMAT. Previously it allowed the
  upload but named the file "(nil)" (without the quotes). Test case 524
  verifies.

- Added a check for getprotobyname in configure so that it'll be used, thanks
  to Gisle Vanem's change the other day.

Daniel (28 February 2006)
- Dan Fandrich prevented curl from getting stuck in an endless loop in case we
  are out of file handles very early in curl's code where it makes sure that
  0, 1 and 2 aren't gonna be used by the lib for transfers.

Daniel (27 February 2006)
- Marty Kuhrt pointed out that there were two VMS-specific files missing in
  the release archive.

Version 7.15.2 (27 February 2006)

Daniel (22 February 2006)
- Lots of work and analysis by "xbx___" in bug #1431750
  (http://curl.haxx.se/bug/view.cgi?id=1431750) helped me identify and fix two
  different but related bugs:

  1) Removing an easy handle from a multi handle before the transfer is done
     could leave a connection in the connection cache for that handle that is
     in a state that isn't suitable for re-use. A subsequent re-use could then
     read from a NULL pointer and segfault.

  2) When an easy handle was removed from the multi handle, there could be an
     outstanding c-ares DNS name resolve request. When the response arrived,
     it caused havoc since the connection struct it "belonged" to could've
     been freed already.

  Now Curl_done() is called when an easy handle is removed from a multi handle
  pre-maturely (that is, before the transfer was complteted). Curl_done() also
  makes sure to cancel all (if any) outstanding c-ares requests.

Daniel (21 February 2006)
- Peter Su added support for SOCKS4 proxies. Enable this by setting the proxy
  type to the already provided type CURLPROXY_SOCKS4.

  I added a --socks4 option that works like the current --socks5 option but
  instead use the socks4 protocol.

Daniel (20 February 2006)
- Shmulik Regev fixed an issue with multi-pass authentication and compressed
  content when libcurl didn't honor the internal ignorebody flag.

Daniel (18 February 2006)
- Ulf Härnhammar fixed a format string (printf style) problem in the Negotiate
  code. It should however not be the cause of any troubles. He also fixed a
  few similar problems in the HTTP test server code.

Daniel (17 February 2006)
- Shmulik Regev provided a fix for the DNS cache when using short life times,
  as previously it could be holding on to old cached entries longer than
  requested.

Daniel (11 February 2006)
- Karl Moerder added the CURLOPT_CONNECT_ONLY and CURLINFO_LASTSOCKET options
  that an app can use to let libcurl only connect to a remote host and then
  extract the socket from libcurl. libcurl will then not attempt to do any
  transfer at all after the connect is done.

- Kent Boortz improved the configure check for GnuTLS to properly set LIBS
  instead of LDFLAGS.

Daniel (8 February 2006)
- Philippe Vaucher provided a brilliant piece of test code that show a problem
  with re-used FTP connections. If the second request on the same connection
  was set not to fetch a "body", libcurl could get confused and consider it an
  attempt to use a dead connection and would go acting mighty strange.

Daniel (2 February 2006)
- Make --limit-rate [num] mean bytes. It used to be that but it broke in my
  change done in November 2005.

Daniel (30 January 2006)
- Added CURLOPT_LOCALPORT and CURLOPT_LOCALPORTRANGE to libcurl. Set with the
  curl tool with --local-port. Plain and simply set the range of ports to bind
  the local end of connections to. Implemented on to popular demand.

- Based on an error report by Philippe Vaucher, we no longer count a retried
  connection setup as a follow-redirect. It turns out 1) this fails when a FTP
  connection is re-setup and 2) it does make the max-redirs counter behave
  wrong.

Daniel (24 January 2006)
- Michal Marek provided a patch for FTP that makes libcurl continue to try
  PASV even after EPSV returned a positive response code, if libcurl failed to
  connect to the port number the EPSV response said. Obviously some people are
