2014-11-26smtp: Added support for the conversion of Unix newlines during mail sendSteve Holme
Added support for the automatic conversion of Unix newlines to CRLF during mail uploads. Feature: http://curl.haxx.se/bug/view.cgi?id=1456
2014-11-16kerberos: Use symbol qualified with _KERBEROS5Michael Osipov
For consistency renamed USE_KRB5 to USE_KERBEROS5.
2014-11-02sasl: Fixed Kerberos V5 inclusion when CURL_DISABLE_CRYPTO_AUTH is usedSteve Holme
Typically the USE_WINDOWS_SSPI definition would not be used when the CURL_DISABLE_CRYPTO_AUTH define is, however, it is still a valid build configuration and, as such, the SASL Kerberos V5 (GSSAPI) authentication data structures and functions would incorrectly be used when they shouldn't be. Introduced a new USE_KRB5 definition that takes into account the use of CURL_DISABLE_CRYPTO_AUTH like USE_SPNEGO and USE_NTLM do.
2014-09-30smtp: Fixed intermittent "SSL3_WRITE_PENDING: bad write retry" errorBill Nagel
This patch fixes the "SSL3_WRITE_PENDING: bad write retry" error that sometimes occurs when sending an email over SMTPS with OpenSSL. OpenSSL appears to require the same pointer on a write that follows a retry (CURLE_AGAIN) as discussed here: http://stackoverflow.com/questions/2997218/why-am-i-getting-error1409f07fssl-routinesssl3-write-pending-bad-write-retr
2014-09-07Ensure progress.size_dl/progress.size_ul are always >= 0Brandon Casey
Historically the default "unknown" value for progress.size_dl and progress.size_ul has been zero, since these values are initialized implicitly by the calloc that allocates the curl handle that these variables are a part of. Users of curl that install progress callbacks may expect these values to always be >= 0. Currently it is possible for progress.size_dl and progress.size_ul to by set to a value of -1, if Curl_pgrsSetDownloadSize() or Curl_pgrsSetUploadSize() are passed a "size" of -1 (which a few places currently do, and a following patch will add more). So lets update Curl_pgrsSetDownloadSize() and Curl_pgrsSetUploadSize() so they make sure that these variables always contain a value that is >= 0. Updates test579 and test599.

2014-08-15smtp: Added support for GSSAPI (Kerberos V5) authentication via Windows SSPISteve Holme
2014-08-14email: Introduced the GSSAPI statesSteve Holme
2014-07-30smtp: fixed a segfault during test 1320 torture testDan Fandrich
Under these circumstances, the connection hasn't been fully established and smtp_connect hasn't been called, yet smtp_done still calls the state machine which dereferences the NULL conn pointer in struct pingpong.
2014-05-22bits.close: introduce connection close trackingDaniel Stenberg
Make all code use connclose() and connkeep() when changing the "close state" for a connection. These two macros take a string argument with an explanation, and debug builds of curl will include that in the debug output. Helps tracking connection re-use/close issues.
2014-04-26INFILESIZE: fields in UserDefined must not be changed run-timeDaniel Stenberg
set.infilesize in this case was modified in several places, which could lead to repeated requests using the same handle to get unintendent/wrong consequences based on what the previous request did!
2014-04-23handler: make 'protocol' always specified as a single bitDaniel Stenberg
This makes the findprotocol() function work as intended so that libcurl can properly be restricted to not support HTTP while still supporting HTTPS - since the HTTPS handler previously set both the HTTP and HTTPS bits in the protocol field. This fixes --proto and --proto-redir for most SSL protocols. This is done by adding a few new convenience defines that groups HTTP and HTTPS, FTP and FTPS etc that should then be used when the code wants to check for both protocols at once. PROTO_FAMILY_[protocol] style. Bug: https://github.com/bagder/curl/pull/97 Reported-by: drizzt
2014-04-05sasl: Combined DIGEST-MD5 message decoding and generationSteve Holme
2014-04-01smtp: Fixed login denied with a RFC-821 based serverSteve Holme
In addition to commit fe260b75e7 fixed the same issue for RFC-821 based SMTP servers and allow the credientials to be given to curl even though they are not used with the server.
2014-03-28smtp: Fixed login denied when server doesn't support AUTH capabilitySteve Holme
Specifying user credentials when the SMTP server doesn't support authentication would cause curl to display "No known authentication mechanisms supported!" and return CURLE_LOGIN_DENIED. Reported-by: Tom Sparrow Bug: http://curl.haxx.se/mail/lib-2014-03/0173.html
2013-12-31mprintf: Replaced internal usage of FORMAT_OFF_T and FORMAT_OFF_TUSteve Holme
Following commit 0aafd77fa4c6f2, replaced the internal usage of FORMAT_OFF_T and FORMAT_OFF_TU with the external versions that we expect API programmers to use. This negates the need for separate definitions which were subtly different under different platforms/compilers.
2013-12-22email: Fixed segfault introduced in commit 195b63f99c2fe3Steve Holme

2013-12-20vtls: renamed sslgen.[ch] to vtls.[ch]Daniel Stenberg
2013-12-20vtls: created subdir, moved sslgen.[ch] there, updated all include linesDaniel Stenberg
2013-12-18imap/pop3/smtp: Added support for SASL authentication downgradesSteve Holme
Added support for downgrading the SASL authentication mechanism when the decoding of CRAM-MD5, DIGEST-MD5 and NTLM messages fails. This enhances the previously added support for graceful cancellation by allowing the client to retry a lesser SASL mechanism such as LOGIN or PLAIN, or even APOP / clear text (in the case of POP3 and IMAP) when supported by the server.
2013-12-18smtp: fix compiler warningDaniel Stenberg
smtp.c:478:21: error: unused variable 'smtpc' [-Werror=unused-variable]
2013-12-18smtp: Moved the calculation of SASL login details into a separate functionSteve Holme
2013-12-18smtp: Moved the sending of the AUTH command into a separate functionSteve Holme
2013-12-17email: Renamed *_perform_authenticate() functionsSteve Holme
In preparation for the upcoming SASL downgrade feature renamed the imap__perform_authenticate(), pop3__perform_authenticate() and smtp__perform_authenticate() functions.
2013-11-23smtp: Post SMTP command expansion tidy upSteve Holme
Removed unnecessary SMTP_STOP state changes on failure. Removed hard return on failure in smtp_state_data_resp().
2013-11-17smtp: Fixed space being sent in non --mail-rcpt based requestsSteve Holme
Commands such as NOOP, RSET and HELP would be sent with a space at the end of the command, for example: "NOOP ".
2013-11-17smtp: Changed the default command to HELP when no options are specifiedSteve Holme
Otherwise a NOOP operation would be performed which a) only returns a single line response and not a multiline response where -I needs to be used, and b) provides an inconsistent user experience compared to that of the POP3 and IMAP protocols.
2013-11-17smtp:Fixed memory leak from commit dac01ff6d788b2Steve Holme
The buffer allocated by smtp_parse_custom_request() was not freed.
2013-11-15smtp: Fixed broken RCPT TO from commit 0ea4a80bb23666Steve Holme

2013-11-15smtp: Added support for VRFY and EXPN commandsSteve Holme
2013-11-15smtp: Added support for NOOP and RSET commandsSteve Holme
2013-11-15smtp: Fixed handling of multiline server greeting responsesSteve Holme
Incorrectly processed multiline server greeting responses as "wanted" continue responses in smtp_endofresp(), from commit f16c0de4e9bbe3, which in turn broke the SMTP server detection in the test suite, because the EHLO command would not be sent.
2013-11-15smtp.c: Fixed compilation error from commit f16c0de4e9bbe3Steve Holme
warning: unused variable 'smtpc'
2013-11-15smtp: Fixed processing of more than one response when sent in same packetSteve Holme
Added a loop to smtp_statemach_act() in which Curl_pp_readresp() is called until the cache is drained. Without this multiple responses received in a single packet could result in a hang or delay.
2013-11-15smtp: Moved EHLO response handling to smtp_state_ehlo_resp()Steve Holme
Similar to the processing of untagged CAPABILITY responses in IMAP moved the processing of multiline EHLO responses to smtp_state_ehlo_resp() and introduced an internal response code of one to differentiate a multiline continuation from the end of command. This also allows for the separate processing of multiline responses from commands such as VRFY and EXPN.

2013-10-27email: Corrected a couple of typos from 1e39b95682781fSteve Holme
2013-10-27email: Added support for canceling CRAM-MD5 authenticationSteve Holme
2013-10-27email: Added initial support for cancelling authenticationSteve Holme
Should a client application fail to decode an authentication message received from a server, or not support any of the parameters given by the server in the message, then the authentication phrase should be cancelled gracefully by the client rather than simply terminating the connection. The authentication phrase should be cancelled by simply sending a '*' to the server, in response to erroneous data being received, as per RFC-3501, RFC-4954 and RFC-5034. This patch adds the necessary state machine constants and appropriate response handlers in order to add this functionality for the CRAM-MD5, DIGEST-MD5 and NTLM authentication mechanisms.
2013-10-27email: Moved authentication message parsing into a separate functionSteve Holme
...in preparation for upcoming modifications.
2013-10-26email: Added references to SASL LOGIN authentication draft proposalSteve Holme
2013-10-26smtp: Fixed response code parsing for bad AUTH continuation responsesSteve Holme
This workaround had been previously been implemented for IMAP and POP3 but not SMTP. Some of the recent test case additions implemented this behaviour to emulate a bad server and the SMTP code didn't cope with it.
