- vms: config-vms.h is removed, no use trying to distribute it

- RELEASE-NOTES: mention the SASL buffer overflow

- [Eldar Zaitov brought this change]

  Curl_sasl_create_digest_md5_message: fix buffer overflow
  
  When negotiating SASL DIGEST-MD5 authentication, the function
  Curl_sasl_create_digest_md5_message() uses the data provided from the
  server without doing the proper length checks and that data is then
  appended to a local fixed-size buffer on the stack.
  
  This vulnerability can be exploited by someone who is in control of a
  server that a libcurl based program is accessing with POP3, SMTP or
  IMAP. For applications that accept user provided URLs, it is also
  thinkable that a malicious user would feed an application with a URL to
  a server hosting code targetting this flaw.

  8 more bug fixes mentioned

- [John E. Malmberg brought this change]

  VMS: fix and generate the VMS build config
  
  config_h.com is a new file that generates a config.h file based on the
  curl_config.h.in file and a quick scan of the configure script.  This is
  actually a generic procedure that is shared with other VMS packages.
  
  The existing pre-built config-vms.h had over 100 entries that were not
  correct and in some cases conflicted with the build options available in
  the build_vms.com.
  
  generate_config_vms_h_curl.com is a helper procedure to the
  config_h.com.  It covers the cases that the generic config_h.com is not
  able to figure out, and accepts input from the build_vms.com procedure.
  
  build_curlbuild_h.com is a new file to generate the curlbuild.h file
  that Curl is now using when it is using a curl_config.h file.
  
  post-config-vms.h is a new file that is needed to provide VMS specific
  definitions, and most of them need to be set before the system header
  files are included.
  
  The VMS build procedure is fixed:
  
     1. Fixed to link in the correct HP ssl library.
     2. Fixed to detect if HP Kerberos is installed.
     3. Fixed to detect if HP LDAP is installed.
     4. Fixed to detect if gnv$libzshr is installed.
     5. Simplified the input parameter parsing to not use a loop.
     6. Warn that 64 bit pointer option support is not complete
        in comments.
     7. Default to IEEE floating if platform supports it so
        resulting libcurl will be compatible with other
        open source projects on VMS.
     8. Default to LARGEFILE if platform supports it.
     9. Default to enable SSL, LDAP, Kerberos, libz
        if the libraries are present.
     10. Build with exact case global symbols for libcurl.
     11. Generate linker option file needed.
     12. Compiler list option only commonly needed items.
     13. fulllist option for those who really want it.
     14. Create debug symbol file on Alpha, IA64.

- Curl_proxyCONNECT: return once CONNECT is sent
  
  By doing this unconditionally, we infer a simpler and more defined
  behavior. This also has the upside that test 1021 no longer fails for me
  even if I run with valgrind.
  
  Also fixed some wrong comments.

Marc Hoersken (5 Feb 2013)
- schannel: Removed extended error connection setup flag
  
  According KB975858 this flag may cause problems on Windows 7 and
  Windows Server 2008 R2 systems. Extended error information is not
  currently used by libcurl and therefore not a requirement.
  
  The flag may improve the SSL-connection shutdown in case of an
  error. This means it might be a good improvement in the future.

- xc-cc-check.m4: re-evaluate exporting and AC_SUBST'ing vars
  
  Notes:
  
  When running a configure script that has nested packages (for example
  libcurl's configure with --enable-ares and c-ares sources embedded in
  curl tree) and AC_CONFIG_SUBDIRS([nested-subdir]) machinery is used to
  automatically run the nested configure script from within the parent
  configure script, it happens that the nested _shell_ script will
  inherit shell variables exported from the parent _shell_ script.
  
  If for example parent configure script sets and exports LDFLAGS and LIBS
  variables with proper values in order to link either a parent library or
  program with a library which will be configured and built by a nested
  package; It will happen that when the nested configure script runs, the
  nested library does not exist yet and _any_ link-test done in the nested
  configure will fail, such as those that autoconf macros perform in order
  to detect existing compiler and its characteristics, the result is that
  the nested configure script will fail with errors such as:
  
  configure: error: C compiler cannot create executables
  
  For now, we no longer export variables previously exported here.
  
  On the other hand, AC_SUBST'ing them is appropriate and even with nested
  packages each package's config.status gets its own package values.
  
  So we reinstate AC_SUBST'ing previously AC_SUBST'ed variables.

  --libcurl: fix for non-zero default options
  
  If the default value for an option taking a long as its value is non
  zero, and it is set by zero by a command line option, then that command
  line option is not reflected in --libcurl's output. This is because line
  520-521 of tool_setopt.c look like:
  
  if(!lval)
      skip = TRUE;
  
  An example of a command-line option doing so is the -k option that sets
  CURLOPT_SLL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST to 0L, when the
  defaults are non-zero.

- commit bc682cbd follow-up

- build: use per-target '_CPPFLAGS' for those currently using default
  
  Automake documents that doing this will make it choose a different name
  for intermediate object files even when sharing source files across
  targets of same Makefile.am.
  
  Up to automake 1.13.1 target's intermediate object files were placed
  in the build subdirectory of the target. We depended on this, probably
  undocumented behavior, to achieve same behavior as if a per-target flag
  had been specified when building targets that actually belong to
  different Makefile.am files.
  
  It seems automake 1.13.2 is going to break behavior mentioned above.
  
  So, lets use a documented behavior in order to achieve same purpose,
  across automake versions, no matter where automake wishes to place
  intermediate object files.
  
  Our build targets that already were using a per-target '_CFLAGS' or
  '_CPPFLAGS' need no 'fixing', these were already 'fixed'. The only
  Makefile.am or Makefile.in files in libcurl's source tree touched by
  this 'fix' are tests/libtest/Makefile.inc and tests/unit/Makefile.inc.

- nss: clear session cache if a client cert from file is used
  
  This commit fixes a regression introduced in 052a08ff.
  
  NSS caches certs/keys returned by the SSL_GetClientAuthDataHook callback
  and if we connect second time to the same server, the cached cert/key
  pair is used.  If we use multiple client certificates for different
  paths on the same server, we need to clear the session cache to force
  NSS to call the hook again.  The commit 052a08ff prevented the session
  cache from being cleared if a client certificate from file was used.
  
  The condition is now fixed to cover both cases: consssl->client_nickname
  is not NULL if a client certificate from the NSS database is used and
  connssl->obj_clicert is not NULL if a client certificate from file is
  used.

  "Sounds like the COFF debug info generation has bit-rotted in GCC.
   Nothing new here, no other platform uses COFF AFAIK."
  
  So lets drop it too.

- curl: ignore SIGPIPE - compilation fix

- build: fix circular header inclusion with other packages
  
  This commit renames lib/setup.h to lib/curl_setup.h and
  renames lib/setup_once.h to lib/curl_setup_once.h.
  
  Removes the need and usage of a header inclusion guard foreign
  to libcurl. [1]
  
  Removes the need and presence of an alarming notice we carried
  in old setup_once.h [2]
  
  ----------------------------------------
  
  1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
      up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
      this single inclusion guard is enough to ensure that inclusion of
      lib/setup_once.h done from lib/setup.h is only done once.
  
      Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
      protect inclusion of setup_once.h even after commit ec691ca3, this
      was to avoid a circular header inclusion triggered when building a
      c-ares enabled version with c-ares sources available which also has
      a setup_once.h header. Commit ec691ca3 exposes the real nature of
      __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
      foreign to libcurl belonging to c-ares's setup_once.h
  
      The renaming this commit does, fixes the circular header inclusion,
      and as such removes the need and usage of a header inclusion guard
      foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.
  
  2 - Due to the circular interdependency of old lib/setup_once.h and the
      c-ares setup_once.h header, old file lib/setup_once.h has carried
      back from 2006 up to now days an alarming and prominent notice about
      the need of keeping libcurl's and c-ares's setup_once.h in sync.
  
      Given that this commit fixes the circular interdependency, the need
      and presence of mentioned notice is removed.
  
      All mentioned interdependencies come back from now old days when
      the c-ares project lived inside a curl subdirectory. This commit
      removes last traces of such fact.

- curl: ignore SIGPIPE
  
  This is a work-around for bug #1180 which is really libcurl's inability
  to ignore SIGPIPE in a few cases. With this work-around at least curl

- configure: update req to 2.59
  
  I ran the 2.59 version of autoupdate that updates obsoleted configure.ac
  constructs to the 2.59 standard. With a little hands-on fiddling I
  prevented it from ruining the quoting in AS_HELP_STRING() uses.
  
  I subsequently also bumped the required autoconf version to 2.59
  (released in December 2003) as I don't have an older autoconf version
  around to test with and I can't be bothered to install one either...

- mk-ca-bundle.1: convert syntax to what's used elsewhere
  
  ... mostly to make sure roffit works better on it, but also to make our
  man pages use a more unified style.

- mk-ca-bundle.1: mention new -f, fix outputfile output
  
  also edited a few sentences to become more verbose

- mk-ca-bundle: add -f, support passing to stdout and more
  
  1. When the downloaded data file from Mozilla is current, but the output
  bundle does not exist: continue processing to create the bundle.  The
  goal is to have the output file - not just download the latest input.
  
  2. added -f option to force re-processing the file.  Useful for
  debugging/testing the process.
  
  3. added support for output to '-' (stdout), allowing the output to be
  piped.
  
  4. All progress and error messages go to STDERR rather than STDOUT (3)
  
  5. The script opened and closed the output file many times
  unnecessarily.  It now opens it once, does the output and closes it.
  
  6. Backup of the input files happens after successful processing, not
  before.
  
  7. The output is written to a temporary file, and renamed to the
  requested name after backup - this greatly reduces the window where the
  file can be seen partially written.
  
  8. all die calls have a \n at the end to suppress perl's traceback - the
  traceback isn't useful to end users.

- curl_setup.h: remove redundant include guard

- build and tests: curl_10char_object_name() shell function
  
  lib/objnames.inc provides definition of curl_10char_object_name() shell
  function. The intended purpose of this function is to transliterate a
  (*.c) source file name that may be longer than 10 characters, or not,
  into a string with at most 10 characters which may be used as an OS/400
  object name.
  
  Test case 1221 does unit testng of this function and also verifies
  that it is possible to generate distinct short object names for all
  curl and libcurl *.c source file names.
  
  lib/objnames-test.sh is the shell script used for test case 1221.
  
  tests/runtests.pl modified to accept shell script test cases.
  
  More details inside lib/objnames.inc and lib/objnames-test.sh

- configure.ac: replace AM_CONFIG_HEADER with AC_CONFIG_HEADERS
  
  automake 1.13 errors if AM_CONFIG_HEADER is used in configure script.
  automake 1.13 no longer autoupdates AM_CONFIG_HEADER to
  AC_CONFIG_HEADERS, thing which automake has been doing since automake
  version 1.7
  
  Given that our first automake supported version is automake 1.7,
  simply replacing AM_CONFIG_HEADER usage with AC_CONFIG_HEADERS seems
  enough to yet support same automake versions.
  
  Dave Reisner reported issue with 1.13 and provided patch.
  
  http://curl.haxx.se/mail/lib-2012-12/0246.html

- curl-override.m4: provide AC_CONFIG_MACRO_DIR definition conditionally
  
  Provide a 'traceable' AC_CONFIG_MACRO_DIR definition only when using
  an autoconf version that does not provide it, instead of what we were
  doing up to now of providing and overriding AC_CONFIG_MACRO_DIR for
  all autoconf versions.

- imap.c: Minor follow up tidy up

- imap: Code tidy up prior to adding support for the CAPABILITY command
  
  * Changing the order of the state machine to represent the order in
    which commands are sent to the server.
  
  * Reworking the imap_endofresp() function as the FETCH response doesn't
    include the command id and shouldn't be part of the length comparison
    that takes into account the id string.

- pop3_doing: Applied debug info message when function fails
  
  Applied the same debug message as used in smtp_doing() and imap_doing()
  when pop3_multi_statemach() fails.

- imap_doing: don't call imap_dophase_done() if already failed
  
  Applied the POP3 fix from commit 2897ce7dc2e1 so imap_dophase_done()
  isn't called if imap_multi_statemach() fails.

- smtp_doing: don't call smtp_dophase_done() if already failed

- imap.c: Fixed bad state error when logging in with invalid credentials
  
  Fixed a problem with the state machine when attempting to log in with
  invalid credentials. The server would report login failure but libcurl
  would not read the response due to inappropriate IMAP_STOP states being
  set after the login was sent.

  This is in preparation of adding SASL based authentication.

- pop3.c: Minor code tidy up
  
  Minor tidy up of comments and layout prior to next part of imap work.

  darwinssl: Fixed inability to disable peer verification
  
  ... on Snow Leopard and Lion
  
  Snow Leopard introduced the SSLSetSessionOption() function, but it
  doesn't disable peer verification as expected on Snow Leopard or
  Lion (it works as expected in Mountain Lion). So we now use sysctl()
  to detect whether or not the user is using Snow Leopard or Lion,
  and if that's the case, then we now use the deprecated
  SSLSetEnableCertVerify() function instead to disable peer verification.

  mentioned functions we really don't care which linkage is the
  appropriate one, but on the other hand, the double declaration emmits

  configure: fix cross pkg-config detection
  
  When cross-compiling, CURL_CHECK_PKGCONFIG was checking for the cross
  pkg-config using ${host}-pkg-config.
  
  The gold standard for doing this correctly is pkg-config's own macro,
  PKG_PROG_PKG_CONFIG.  However, on the assumption that you have a good
  reason not to use that directly (reduced dependencies for maintainer
  builds?), the behaviour of cURL's version should at least match.
  PKG_PROG_PKG_CONFIG uses AC_PATH_TOOL, which ultimately ends up trying
  ${host_alias}-pkg-config; this is not quite the same as what cURL does,
  and may differ because ${host} has been run through config.sub.  For
  instance, when cross-building to the armhf architecture on Ubuntu,
  ${host_alias} is arm-linux-gnueabihf while ${host} is
  arm-unknown-linux-gnueabihf.  This may also have been the cause of the
  problem reported at http://curl.haxx.se/mail/lib-2012-04/0224.html.
  
  AC_PATH_TOOL is significantly simpler than cURL's current code, and
  dates back to well before the current minimum of Autoconf 2.57, so let's
  use it instead.

- [Linus Nielsen Feltzing brought this change]

  Introducing a new persistent connection caching system using "bundles".
  
  A bundle is a list of all persistent connections to the same host.
  The connection cache consists of a hash of bundles, with the
  hostname as the key.
  The benefits may not be obvious, but they are two:
  
  1) Faster search for connections to reuse, since the hash
     lookup only finds connections to the host in question.
  2) It lays out the groundworks for an upcoming patch,
     which will introduce multiple HTTP pipelines.
  
  This patch also removes the awkward list of "closure handles",
  which were needed to send QUIT commands to the FTP server
  when closing a connection.
  Now we allocate a separate closure handle and use that
  one to close all connections.
  
  This has been tested in a live system for a few weeks, and of
  course passes the test suite.

- multi: fix re-sending request on early connection close
  
  This handling already works with the easy-interface code. When a request

  same time as the request is sent, the situation may occur so that we can
  send the request and we discover the broken connection as a RECV_ERROR
  in the PERFORM state and then the request needs to be retried on a fresh
  connection. Test 64 broke with 'multi-always-internally'.

  Digest: Add microseconds into nounce calculation
  
  When using only 1 second precision, curl doesn't create new cnonce
  values quickly enough for all uses.
  
  For example, issuing the following command multiple times to a recent
  Tomcat causes authentication failures:
  
  curl --digest -utest:test http://tomcat.test.com:8080/manager/list
  
  This is because curl uses the same cnonce for several seconds, but
  doesn't increment the nonce counter.  Tomcat correctly interprets
  this as a replay attack and rejects the request.
  
  When microsecond-precision is available, this commit causes curl to
  change cnonce values much more frequently.
  
  With microsecond resolution, increasing the nounce length used in the
  headers to 32 was made to further reduce the risk of duplication.

  SSL: Several SSL-backend related fixes
  
  axTLS:
  
  This will make the axTLS backend perform the RFC2818 checks, honoring
  the VERIFYHOST setting similar to the OpenSSL backend.
  
  Generic for OpenSSL and axTLS:
  
  Move the hostcheck and cert_hostcheck functions from the lib/ssluse.c
  files to make them genericly available for both the OpenSSL, axTLS and
  other SSL backends. They are now in the new lib/hostcheck.c file.
  
  CyaSSL:
  
  CyaSSL now also has the RFC2818 checks enabled by default. There is a
  limitation that the verifyhost can not be enabled exclusively on the
  Subject CN field comparison. This SSL backend will thus behave like the
  NSS and the GnuTLS (meaning: RFC2818 ok, or bust). In other words:
  setting verifyhost to 0 or 1 will disable the Subject Alt Names checks
  too.
  
  Schannel:
  
  Updated the schannel information messages: Split the IP address usage
  message from the verifyhost setting and changed the message about
  disabling SNI (Server Name Indication, used in HTTP virtual hosting)
  into a message stating that the Subject Alternative Names checks are
  being disabled when verifyhost is set to 0 or 1. As a side effect of
  switching off the RFC2818 related servername checks with
  SCH_CRED_NO_SERVERNAME_CHECK
  (http://msdn.microsoft.com/en-us/library/aa923430.aspx) the SNI feature
  is being disabled. This effect is not documented in MSDN, but Wireshark
  output clearly shows the effect (details on the libcurl maillist).
  
  PolarSSL:
  
  Fix the prototype change in PolarSSL of ssl_set_session() and the move
  of the peer_cert from the ssl_context to the ssl_session. Found this
  change in the PolarSSL SVN between r1316 and r1317 where the
  POLARSSL_VERSION_NUMBER was at 0x01010100. But to accommodate the Ubuntu
  PolarSSL version 1.1.4 the check is to discriminate between lower then
  PolarSSL version 1.2.0 and 1.2.0 and higher. Note: The PolarSSL SVN
  trunk jumped from version 1.1.1 to 1.2.0.
  
  Generic:
  
  All the SSL backends are fixed and checked to work with the
  ssl.verifyhost as a boolean, which is an internal API change.

- URL parser: cut off '#' fragments from URLs (better)
  
  The existing logic only cut off the fragment from the separate 'path'

- Revert "Zero out auth structs before transfer"
  
  This reverts commit ce8311c7e49eca93c136b58efa6763853541ec97.
  
  The commit made test 2024 work but caused a regression with repeated
  Digest authentication. We need to fix this differently.

- CURLOPT_SSL_VERIFYHOST: stop supporting the 1 value
  
  After a research team wrote a document[1] that found several live source
  codes out there in the wild that misused the CURLOPT_SSL_VERIFYHOST
  option thinking it was a boolean, this change now bans 1 as a value and
  will make libcurl return error for it.
  
  1 was never a sensible value to use in production but was introduced
  back in the days to help debugging. It was always documented clearly
  this way.
  
  1 was never supported by all SSL backends in libcurl, so this cleanup
  makes the treatment of it unified.
  
  The report's list of mistakes for this option were all PHP code and
  while there's a binding layer between libcurl and PHP, the PHP team has
  decided that they have an as thin layer as possible on top of libcurl so
  they will not alter or specifically filter a 'TRUE' value for this
  particular option. I sympathize with that position.

- curl_schannel.c: Fixed caching more data than required
  
  Do not fill the decrypted data buffer with more data unless
  required in order to return the requested amount of data.

- curl_schannel: Removed buffer limit and optimized buffer strategy
  
  Since there are servers that seem to return very big encrypted
  data packages, we need to be able to handle those without having
  an internal size limit. To avoid the buffer growing to fast to
  early the initial size was decreased and the minimum free space
  in the buffer was decreased as well.

- lib/socks.c: Merged two size variables into one

- lib/socks.c: Avoid type conversions where possible
  
  Streamlined variable names and types to avoid type conversions that
  may result in data being lost on non 32-bit systems.

- multi_runsingle: CURLOPT_LOW_SPEED_* fix for rate limitation
  
  During the periods of rate limitation, the speedcheck function wasn't
  called and thus the values weren't updated accordingly and it would then
  easily trigger wrongly once data got transferred again.
  
  Also, the progress callback's return code was not acknowledged in this
  state so it could make an "abort" return code to get ignored and not
  have the documented effect of aborting an ongoing transfer.

  tool_metalink.c: Filtered resource URLs by type
  
  In Metalink v3, the type attribute of url element indicates the
  type of the resource the URL points to. It can include URL to the
  meta data, such as BitTorrent metainfo file.  In Curl, we are not
  interested in these meta data URLs. Instead, we are only
  interested in the HTTP and FTP URLs. This change filters out
  non-HTTP and FTP URLs. If we don't filter out them, it will be
  downloaded by curl and hash check will fail if hash is provided
  and next URL will be tried. This change will cut this useless
  network transfer.

  SOCKET type is unsigned.

- nss.c: Fixed warning: 'err' may be used uninitialized in this function

- tool_metalink.c: Fixed error: 'O_BINARY' undeclared
  
  Check for O_BINARY which is not available on every system.

- tool_metalink.c: Fixed validation of binary files containing EOF
  
  Since Windows/MinGW threat 0x1A as the EOF character, reading binary
  files which contain that byte does not work using text mode.
  The read function will only read until the first 0x1A byte. This
  means that the hash is not computed from the whole file and the
  final validation check using hash comparision fails.

- winbuild: Added support for building with SPNEGO enabled
  
  Since Simple and Protected GSSAPI Negotiation Mechanism
  is already implemented in curl and supported by the MinGW
  builds, this change adds build support to winbuild makefiles.

- winbuild: Adjusted order of options to generated config name
  
  Cleaned up order of handled build options by ordering them

  ftp: active conn, place calling sockopt callback at the end of function
  
  Commit b91d29a28e170c16d65d956db79f2cd3a82372d2 introduces a bug and breaks Curl_closesocket function. sock_accepted flag for the second socket should be tagged as TRUE before the sockopt callback is called because in case the callback returns an error, Curl_closesocket function is going to call the - fclosesocket - callback for the accept()ed socket

- [Gokhan Sengun brought this change]

  ftp: active conn, allow application to set sockopt after accept() call
  
  For active FTP connections, applications may need setting the sockopt after accept() call returns successful. This fix gives a call to the callback registered with CURL_SOCKOPTFUNCTION option.

Applications may use this parameter to distinguish between socket types.

- configure: remove the --enable/disable-nonblocking options

  docs: mention CURLSSH_AUTH_AGENT

- [Armel Asselin brought this change]

  SSH: added agent based authentication
  
  CURLSSH_AUTH_AGENT is a new auth type for SSH

- bump version to 7.28.0
  
  I am about to merge the first patch that adds changes into the pending
  release, and thus we bump the minor number.

- RELEASE-NOTES: added missing link

- curl_version: fixed Value stored to 'len' is never read
  
  Fixed this (harmless) clang-analyzer warning. Also fixed the source
  indentation level.

- TODO-RELEASE: the (nil) bug is fixed

- add_next_timeout: minor restructure of code
  
  By reading the ->head pointer and using that instead of the ->size
  number to figure out if there's a list remaining we avoid the (false
  positive) clang-analyzer warning that we might dereference of a null
  pointer.

- verbose messages: fixed output of hostnames in re-used connections
  
  I suspect this is a regression introduced in commit 207cf150, included
  since 7.24.0.
  
  Avoid showing '(nil)' as hostname in verbose output by making sure the
  hostname fixup function is called early enough to set the pointers that
  are used for this. The name data is set again for each request even for
  re-used connections to handle multiple hostnames over the same
  connection (like with proxy) or that the casing etc of the host name is
  changed between requests (which has proven to be important at least once
  in the past).
  
  Test1011 was modified to use a redirect with a re-used a connection
  since it then showed the bug and now lo longer does. There's currently
  no easy way to have the test suite detect 'nil' texts in verbose ouputs
  so no tests will detect if this problem gets reintroduced.

- TODO-RELEASE: two bugs fixed
  
  These are now addressed:
  
  323 - patch - select.c / Curl_socket_check() interrupted
  
  325 - Avoid leak of local device string when reusing connection

- curl.1: minor format fix for --data-ascii
  
  ... and removal of trailing whitespace on a single line

  curl man page cleanup

- [Mike Crowe brought this change]

  Avoid leak of local device string when reusing connection
  
  Ensure that the copy of the CURLOPT_INTERFACE string is freed if we
  decide we can reuse an existing connection.

- Curl_socket_check: fix timeout return value for select users
  
  This is the same fix applied for the conditional code that uses select()
  that was already done for the poll specific code in commit
  b61e8b81f5038.

- [Maxime Larocque brought this change]

  Curl_socket_check: fix return code for timeout
  
  We found a problem with ftp transfer using libcurl (7.23 and 7.25)
  inside an application which is receiving unix signals (SIGUSR1,
  SIGUSR2...) almost continuously. (Linux 2.4, PowerPC, HAVE_POLL_FINE
  defined).
  
  Curl_socket_check() uses poll() to wait for the socket, and retries it
  when a signal is received (EINTR). However, if a signal is received and
  it also happens that the timeout has been reached, Curl_socket_check()
  returns -1 instead of 0 (indicating an error instead of a timeout).
  
  In our case, the result is an aborted connection even before the ftp
  banner is received from the server, and a return value of
  CURLE_OUT_OF_MEMORY from curl_easy_perform() (Curl_pp_multi_statemach(),
  in pingpong.c, actually returns OOM if Curl_socket_check() fails :-)
  Funny to debug on a system on which OOM is a possible cause).

- TODO-RELEASE: fixed another bug
  
  bug #3544688 "crash during retry with libcurl and SFTP"

- WSAPoll: disabled on all windows builds
  
  Due to WSAPoll bugs, libcurl does not work as intended. When the cURL
  library is used to setup a connection to an incorrect port, normally the
  result is CURLE_COULDNT_CONNECT, /* 7 */, but due to the bug in WSAPoll,
  the result now is CURLE_OPERATION_TIMEDOUT, /* 28 - the timeout time was
  reached */.
  
  On August 1, Jan Koen Annot opened a case for this to Microsoft Premier
  Online (https://premier.microsoft.com/).  The support engineer handling
  the case wrote that the case description is quite clear.  He will try to
  reproduce the issue and then proceed with troubleshooting it.

- DISABLED: disable the new tests that do NTLM
  
  The tests 2025, 2028 and 2031 don't work for me so I'll have them
  disabled for now until we solve the problem.

Joe Mason (3 Aug 2012)
- Add tests of auth retries

- Cleanup handshake after clean NTLM failure

- Zero out auth structs before transfer

- Add a polling loop in main to read from more than one socket at once. Add the O_NONBLOCK and
  SO_KEEPALIVE flag to all sockets. Note that several loops which used to continue on a return value
  of 0 (theoretical since 0 would never be returned without O_NONBLOCK) now break on 0 so that they
  won't continue reading until after poll is called again.

- Change return values of get_request, accept_connection and service_connection to add a return code
  for non-blocking sockets: now -1 means error or connection finished, 1 means data was read, and 0
  means there is no data available now so need to wait for poll (new return value)

- Hoist the loop out of get_request, and make sure that it can be reentered when a request is
  half-finished.
  
  Note the the req struct used to be re-initialized AFTER reading pipeline data, so now that we
  initialize it from the caller we must be careful not to overwrite the pipeline data.
  
  Also we now need to handle the case where the buffer is already full when get_request is called -
  previously this never happened as it was always called with an empty buffer and looped until done.
  
  Now get_request is called in a loop, so the next step is to run the loop on a socket only when poll
  signals it is readable.

- Move blocks of code from the sws main loop into their own functions for easier refactoring later.
  The next step will be to call the correct function after a poll, rather than looping unconditionally

- Remove the --fork option of sws, since it makes refactoring to use poll more complicated and should
  be redundant once we poll

- Fixed CR issue with Win32 version on MSYS.

- Fixed MSYS <-> Windows path convertion.
  
  Replaced the Windows real path from mount hack with a more

  paths. Tested and confirmed that this works on all MSYS versions
  I have back to a 3 year old one.

- Follow-up fix to detect SSL libs with MinGW.
  
  1) the check for winssl needs to come before nss check
  2) the SSL checks must begin with a new if or else we will
  never find any SSL lib with MinGW.

- Tell git to not convert configure-related files.

- Trial to teach runtests.pl about WinSSL.

- multi_runsingle: added precaution against easy_conn NULL pointer

- tests: verify the stricter numeric option parser
  
  Test 1409 and 1410 verifies the stricter numeric option parser
  introduced the other day in commit f2b6ebed7b.

- SWS: use of uninitialized memory fix
  
  I made "connmon" not get initialized properly before use, and I use the
  big hammer and make sure we always clear the entire struct to avoid any
  problem like this in the future.

- test48: verify that HEAD doesn't close extra
  
  Two commits ago, we fixed a bug where the connction would be closed
  prematurely after a HEAD. Now I added connection-monitor to test 48 and
  added a second HEAD and make sure that both are sent over the same
  connection.
  
  This triggered a failure before the bug fix and now works. Will help us
  avoid a future regression of this kind.

- connection-monitor: always log disconnect when enabled
  
  This makes verifying easier and makes us more sure curl closes the
  connection only at the correct point in time. Adjusted test 206 and 1008
  accordingly and updated the docs for it.

- HEAD: don't force-close after response-headers
  
  A HEAD response has no body length and gets the headers like the
  corresponding GET would so it should not get closed after the response
  based on the same rules. This mistake caused connections that did HEAD
  to get closed too often without a valid reason.

- test 46: use different path lengths to get reliable sort order
  
  Since the order of the cookies is sorted by the length of the paths,

  https_getsock: provided for schannel backend as well
  
  The function https_getsock was only implemented properly when USE_SSLEAY
  or USE_GNUTLS is defined, but it is also necessary for USE_SCHANNEL.
  
  The problem occurs when Curl_read_plain or Curl_write_plain returns
  CURLE_AGAIN. In that case CURL_OK is returned to the multi-interface an
  the used socket is set to state CURL_POLL_REMOVE and the easy-state is
  set to CURLM_STATE_PROTOCONNECT. This is fine, because later the socket
  should be set to CURL_POLL_IN or CURL_POLL_OUT via multi_getsock. That's
  where https_getsock is called and doesn't return any sockets.

- winbuild: Aligned BUILD.WINDOWS.txt and Makefile.vc usage help

- winbuild: Make USE_WINSSL depend on USE_SSPI
  
  Since WinSSL cannot be build without SSPI being enabled,
  USE_WINSSL now defaults to the value of USE_SSPI.
  
  The makefile does now raise an error if WinSSL is enabled
  while SSPI is disabled.

- winbuild: Aligned USE_SSPI with other USE_x defines
  
  Renamed external parameter USE_SSPI = yes/no to ENABLE_SSPI = yes/no.
  Backwards compatible change: USE_SSPI can still be passed as external
  parameter with yes/no value as long as ENABLE_SSPI is not given.
  
  USE_x defines are passed around with true/false values internally,
  USE_SSPI is now aligned to this approach, but still accepts external
  values yes/no being passed, just like the other defines.

- winbuild: Clean up formatting and variable naming
  
  - Changed space usage to line up with the whole file
  - Renamed CFLAGS_SSPI/IPV6 to SSPI/IPV6_CFLAGS to be
    consistent with the other CFLAGS_x variables
  - Make use of existing CFLAGS_IPV6 (previously IPV6_CFLAGS)
    instead of appending directly to CFLAGS

  darwinssl: output cipher with text, remove SNI warning
  
  The code was printing a warning when SNI was set up successfully. Oops.
  
  Printing the cipher number in verbose mode was something only TLS/SSL
  programmers might understand, so I had it print the name of the cipher,
  just like in the OpenSSL code. That'll be at least a little bit easier
  to understand. The SecureTransport API doesn't have a method of getting
  a string from a cipher like OpenSSL does, so I had to generate the
  strings manually.

- tests: use connection-monitor and verify results
  
  Test 1008 and 206 don't show the disconnect since it happens when SWS

  string added.

- http-proxy: keep CONNECT connections alive (for NTLM)
  
  When doing CONNECT requests, libcurl must make sure the connection is
  alive as much as possible. NTLM requires it and it is generally good for
  other cases as well.
  
  NTLM over CONNECT requests has been broken since this regression I
  introduced in my CONNECT cleanup commits that started with 41b02378342,
  included since 7.25.0.

- sws: support <servercmd> for CONNECT requests
  
  I moved out the servercmd parsing into a its own function called
  parse_servercmd() and made sure it gets used also when the test number
  is extracted from CONNECT requests. It turned out sws didn't do that
  previously!

- FILEFORMAT: provided a full description of connection-monitor

- lib503: enable verbose to ease debugging this

- sws: add 'connection-monitor' command support
  
  Using this, the server will output in the protocol log when the
  connection gets disconnected and thus we will verify correctly in the
  test cases that the connection doesn't get closed prematurely. This is
  important for example NTLM to work.
  
  Documentation added to FILEFORMAT, test 503 updated to use this.

  DarwinSSL: allow using NTLM authentication
  
  Allow NTLM authentication when building using SecureTransport (Darwin) for SSL.
  
  This uses CommonCrypto, a cryptography library that ships with all versions of

- ossl_seed: remove leftover RAND_screen check
  
  Before commit 2dded8fedba (dec 2010) there was logic that used
  RAND_screen() at times and now I remove the leftover #ifdef check for
  it.
  
  The seeding code that uses Curl_FormBoundary() in ossl_seed() is dubious
  to keep since it hardly increases randomness but I fear I'll break
  something if I remove it now...

  curl: Restore noprogress and isatty config values.
  
  The noprogress and isatty in Configurable are global, in a sense
  that they persist in one curl invocation. Currently once one
  download writes its response data to tty, they are set to FALSE
  and they are not restored on successive downloads.  This change
  first backups the current noprogress and isatty, and restores
  them when download does not write its data to tty.

- [Tatsuhiro Tsujikawa brought this change]

  curl: Made --metalink option toggle Metalink functionality
  
  In this change, --metalink option no longer takes argument.  If
  it is specified, given URIs are processed as Metalink XML file.
  If given URIs are remote (e.g., http URI), curl downloads it
  first. Regardless URI is local file (e.g., file URI scheme) or
  remote, Metalink XML file is not written to local file system and
  the received data is fed into Metalink XML parser directly.  This
  means with --metalink option, filename related options like -O
  and -o are ignored.
  
  Usage examples:
  
  $ curl --metalink http://example.org/foo.metalink
  
  This will download foo.metalink and parse it and then download
  the URI described there.
  
  $ curl --metalink file://foo.metalink
  
  This will parse local file foo.metalink and then download the URI
  described there.

  curl: Refactored metalink_checksum
  
  When creating metalink_checksum from metalink_checksum_t, first
  check hex digest is valid for the given hash function.  We do
  this check in the order of digest_aliases so that first good
  match will be chosen (strongest hash function available).  As a
  result, the metalinkfile now only contains at most one
  metalink_checksum because other entries are just redundant.

  schannel: Implement new buffer size strategy
  
  Increase decrypted and encrypted cache buffers using limitted
  doubling strategy. More information on the mailinglist:
  http://curl.haxx.se/mail/lib-2012-06/0255.html
  
  It updates the two remaining reallocations that have already been there
  and fixes the other one to use the same "do we need to increase the
  buffer"-condition as the other two.  CURL_SCHANNEL_BUFFER_STEP_SIZE was
  renamed to CURL_SCHANNEL_BUFFER_FREE_SIZE since that is actually what it
  is now.  Since we don't know how much more data we are going to read
  during the handshake, CURL_SCHANNEL_BUFFER_FREE_SIZE is used as the
  minimum free space required in the buffer for the next operation.
  CURL_SCHANNEL_BUFFER_STEP_SIZE was used for that before, too, but since
  we don't have a step size now, the define was renamed.

- Curl_rtsp_parseheader: avoid useless malloc/free
  
  Coverity actually pointed out flawed logic in the previous call to

  uppercase 4 letters. Still, the entire malloc/uppercase/free sequence
  was pointless since the code has already matched the string once in the
  condition that starts the block of code.

  winbuild: Allow SSPI build with or without Schannel
  
  The changes introduced in commit 2bfa57bc32 are not enough
  to make it actually possible to use the USE_WINSSL option.
  Makefile.vc was not updated and the configuration name which is
  used in the build path did not match between both build files.
  
  This patch fixes those issues and introduces the following changes:
  
  - Replaced the -schannel name with -winssl in order to be consistent
  with the other options
  - Added ENABLE_WINSSL option to winbuild/Makefile.vc (default yes)
  - Changed winbuild/MakefileBuild.vc to set USE_WINSSL to true if
  USE_SSL is false and USE_WINSSL was not specified as a parameter
  - Separated WINSSL handling from SSPI handling to be consistent with

  - For all *FUNCTION options, they now all show the complete prototype in

  - I made the phrasing of that "Pass a pointer to a function that matches
    the following prototype" the same for all *FUNCTION option descriptions.
  
  - I removed some uses of 'should'. I think I sometimes over-use this
    word as in many places I actually mean MUST or otherwise more specific
    and not-so-optional synonyms.

  Added USE_NTLM condition compilation around the NTLM functions called
  from pop3_statemach_act() introduced in commit 69f7156ad96877.

- sasl: Moved cram-md5 authentication message creation from smtp.c
  
  Moved the cram-md5 message creation from smtp.c into the sasl module
  to allow for use by other modules such as pop3.

- pop3: Fixed an issue with changes introduced in commit c267c53017bc
  
  Because pop3_endofresp() is called for each line of data yet is not
  passed the line and line length, so we have to use the data pointed to
  by pp->linestart_resp which contains the whole packet, the mechanisms
  were being detected in one call yet the function would be called for
  each line of data.
  
  Using curl with verbose mode enabled would show that one line of data
  would be received in response to the AUTH command, before the AUTH
  <mechanism> command was sent to the server and then the next few lines
  of the original AUTH command would be displayed before the response from
  the AUTH <mechanism> command. This would then cause problems when
  parsing the CRAM-MD5 challenge data as extra data was contained in the
  buffer.
  
  Changed the parsing so that each line is checked for the mechanisms
  and the function returns FALSE until the whole of the AUTH response has
  been processed.

  Renumbered current sections 11 to 17 as 13 to 19.
  
  Additionally added 19.10 Add CURLOPT_MAIL_CLIENT option.

- sasl.c: Fix to avoid warnings introduced in commit d9ca9e9869e8
  
  Applied a fix to avoid warnings on systems where Curl_ntlm_sspi_cleanup()
  is just a nop.

- pop3.c:Corrected typo in commit 69ba0da8272d

- pop3: Fixed the issue of having to supply the user name for all requests
  
  Previously it wasn't possible to connect to POP3 and not specify the
  user name as a CURLE_ACCESS_DENIED error would be returned. This error
  occurred because USER would be sent to the server with a blank user name
  if no mailbox user was specified as the server would reply with -ERR.
  
  This wasn't a problem prior to the 7.26.0 release but with the
  introduction of custom commands the user and/or application developer
  might want to issue a CAPA command without having to log in as a
  specific mailbox user.
  
  Additionally this fix won't send the newly introduced AUTH command if no
  user name is specified.

- pop3.c: Small code tidy up
  
  Corrected lines exceeding 78 characters.
  
  Repositioned some comments and added extra clarity.

- sasl: Corrected variable names in comments and parameters

- pop3: Added support for sasl ntlm authentication

  as well as corresponding <stripfile1> to <stripfile4> ones, that can be used
  in the <verify> section in the same way as the non-numbered ones.

Steve Holme (31 May 2012)
- sasl: Moved login authentication message creation from smtp.c
  
  Moved the login message creation from smtp.c into the sasl module
  to allow for use by other modules such as pop3.

- smtp.c: Reworked message encoding in smtp_state_authpasswd_resp()
  
  Rather than encoding the password message itself the
  smtp_state_authpasswd_resp() function now delegates the work to the same
  function that smtp_state_authlogin_resp() and smtp_authenticate() use
  when constructing the encoded user name.

- smtp.c: Re-factored smtp_auth_login_user() for use with passwords
  
  In preparation for moving to the SASL module re-factored the
  smtp_auth_login_user() function to smtp_auth_login() so that it can be
  used for both user names and passwords as sending both of these under
  the login authentication mechanism is the same.

- pop3: Added support for sasl plain text authentication

- curl_ntlm_msgs.c: Corrected small spelling mistake in comments

- sasl: Moved plain text authentication message creation from smtp.c
  
  Moved the plain text message creation from smtp.c into the sasl module
  to allow for use by other modules such as pop3.

- configure: fix LDAPS disabling related misplaced closing parenthesis

- pop3 test server: allow pop3 test server verification to succeed again
  
  Introduce SUPPORTCAPA and SUPPORTAUTH config commands to allow further
  pop3 test server expansion for tests that require CAPA or AUTH support,
  although this will need some extra work to make it fully functional.

Steve Holme (28 May 2012)
- pop3: Introduced the continue response in pop3_endofresp()

- pop3: Changed response code from O and E to + and -
  
  The POP3 protocol doesn't really have the concept of error codes and
  uses +, +OK and -ERR in response to commands to indicate continue,
  success and error.
  
  The AUTH command is one of those commands that requires multiple pieces
  of data to be sent to the server where the server will respond with + as
  part of the handshaking. This meant changing the values before
  continuing with the next stage of adding authentication support.

- pop3: Small code tidy up following authentication work so far
  
  Changed the order of the state machine to match the order of actual
  events.
  
  Reworked some comments and function parameter positioning that I missed
  the other day.

Steve Holme (27 May 2012)
- DOCS: Corrected the "Added in" version number for CURLOPT_MAIL_AUTH
  
  Additionally corrected another RFC link that I missed yesterday.

- pop3: Added support for SASL based authentication mechanism detection
  
  Added support for detecting the supported SASL authentication mechanisms
  via the AUTH command. There are two ways of detecting them, either by
  using the AUTH command, that will return -ERR if not supported or by
  using the CAPA command which will return SASL and the list of mechanisms
  if supported, not include SASL if SASL authentication is not supported
  or -ERR if the CAPA command is not supported. As such it seems simpler
  to use the AUTH command and fallback to normal clear text authentication
  if the the command is not supported.
  
  Additionally updated the test cases to return -ERR when the AUTH command
  is encountered. Additional test cases will be added when support for the
  individual authentication mechanisms is added.

Daniel Stenberg (27 May 2012)
- pop3: remove trailing whitespace

Steve Holme (27 May 2012)

  introduction of auth-mechanism detection.
  
  Repositioned second and third function variables where they will fit
  within the 78 character line limit.

- [Tatsuhiro Tsujikawa brought this change]

  Check checksum of downloaded file if checksum is available
  
  Metalink file contains several hash types of checksums, such as
  md5, sha-1, sha-256, etc. To deal with these checksums, I created
  abstraction layer based on lib/curl_md5.h and
  lib/md5.c. Basically, they are almost the same but I changed the
  code so that it is not hash type dependent. Currently,
  GNUTLS(nettle or gcrypt) and OpenSSL functions are supported.
  
  Checksum checking is done by reopening download file.  If there
  is an I/O error, the current implementation just prints error
  message and does not try next resource.
  
  In this patch, the supported hash types are: md5, sha-1 and sha-256.

- [Tatsuhiro Tsujikawa brought this change]

  Always create directory hierarchy for Metalink.
  
  Filenames contained in Metalink file can include directory information.
  Filenames are unique in Metalink file, taking into account the directory
  information. So we need to create the directory hierarchy.
  
  Curl has --create-dirs option, but we create directory hierarchy for
  Metalink downloads regardless of the option value.
  
  This patch also put metalink int variable outside of HAVE_LIBMETALINK
  guard. This reduces the number of #ifdefs.

- [Tatsuhiro Tsujikawa brought this change]

  Fixed segmentation fault when Metalink has no valid file or no resource.

- Fix libcurl.pc and curl-config generation for static MingW* cross builds

Daniel Stenberg (25 May 2012)
- [Tatsuhiro Tsujikawa brought this change]

  Made -D option work with -O and -J.
  
  To achieve this, first new structure HeaderData is defined to hold
  necessary data to perform header-related work.  Then tool_header_cb now
  receives HeaderData pointer as userdata.  All header-related work
  (currently, dumping header and Content-Disposition inspection) are done
  in this callback function.  HeaderData.outs->config is used to determine
  whether each work is done.
  
  Unit tests were also updated because after this change, curl code always
  sets CURLOPT_HEADERFUNCTION and CURLOPT_HEADERDATA.
  
  Tested with -O -J -D, -O -J -i and -O -J -D -i and all worked fine.

  As such, libcurl would return the wrong result code from performing the

  returned by the postdata command.

  Fixed compile error with GNUTLS+NETTLE
  
  In nettle/md5.h, md5_init and md5_update are defined as macros to
  nettle_md5_init and nettle_md5_update respectively.  This causes
  error when using MD5_params.md5_init and md5_update.  This patch
  renames these members as md5_init_func and md5_update_func to
  avoid name conflict. For completeness, MD5_params.md5_final was
  also renamed as md5_final_func.
  
  The changes in curl_ntlm_core.c is conversion error and fixed by

- URL parse: reject numerical IPv6 addresses outside brackets
  
  Roman Mamedov spotted (in
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=670126) that curl would
  not complain when given a URL with an IPv6 numerical address without
  brackets. It would simply cut off the last ":[hex]" part and thus not
  work correctly.
  
  That's a URL using an illegal syntax and now libcurl will instead return
  a clear error code and error message detailing the error.
  
  The above mentioned bug report claims this to be a regression but
  libcurl does not guarantee functionality when given URLs that aren't
  following the URL spec (RFC3986 mostly). I consider the fact that it

- HTTP: empty chunked POST ended up in two zero size chunks
  
  When doing a chunked-encoded POST with -d (CURLOPT_POSTFIELDS) and the
  size of the POST was zero length, it made libcurl first send a zero
  chunk and then the terminating one. This could confuse a receiver and it
  should rather just send the terminating chunk as it does with this fix.
  
  Test case 1333 is added to verify.

  Commit 9109cdec11ee5a brought this regression (shipped since 7.24.0).
  
  The singleipconnect() function must not return an error if Curl_socket()
  returns an error. It should then simply return OK and pass a SOCKET_BAD
  back simply because that is how the user of this function expects it to
  work and something else is not fine.

- -# progress meter: avoid superfluous updates and duplicate lines
  
  By comparing if a different "progress point" is reached or not since the
  previous update, the progress function callback for this now avoids many
  superfluous screen updates. This has the nice side-effect that it fixes
  a problem that causes a second progress meter line.
  
  The second line output happened because when we use the -# progress
  meter, we force a newline output after the transfer in the main loop in
  curl, but when libcurl calls the progress callback from
  curl_easy_cleanup() it would then output the progress display
  again. Possibly the naive newline output is wrong but this optimization
  was suitable anyway...

  OpenSSL: Made cert hostname check conform to RFC 6125
  
  This change replaces RFC 2818 based hostname check in OpenSSL build with
  RFC 6125 [1] based one.
  
  The hostname check in RFC 2818 is ambiguous and each project implements
  it in the their own way and they are slightly different. I check curl,
  gnutls, Firefox and Chrome and they are all different.
  
  I don't think there is a bug in current implementation of hostname
  check. But it is not as strict as the modern browsers do. Currently,
  curl allows multiple wildcard character '*' and it matches '.'. (as
  described in the comment in ssluse.c).
  
  Firefox implementation is also based on RFC 2818 but it only allows at
  most one wildcard character and it must be in the left-most label in the
  pattern and the wildcard must not be followed by any character in the
  label.[2] Chromium implementation is based on RFC 6125 as my patch does.
  Firefox and Chromium both require wildcard in the left-most label in the
  presented identifier.
  
  This patch is more strict than the current implementation, so there may
  be some cases where old curl works but new one does not. But at the same
  time I think it is good practice to follow the modern browsers do and
  follow the newer RFC.

- HTTP: reset expected DL/UL sizes on redirects
  
  With FOLLOWLOCATION enabled. When a 3xx page is downloaded and the
  download size was known (like with a Content-Length header), but the
  subsequent URL (transfered after the 3xx page) was chunked encoded, then
  the previous "known download size" would linger and cause the progress
  meter to get incorrect information, ie the former value would remain
  being sent in. This could easily result in downloads that were WAY
  larger than "expected" and would cause >100% outputs with the curl
  command line tool.
  
  Test case 599 was created and it was used to repeat the bug and then
  verify the fix.
