2013-12-25curl_dofree: allow free(NULL)Daniel Stenberg
Previously this memdebug free() replacement didn't properly work with a NULL argument which has made us write code that avoids calling free(NULL) - which causes some extra nuisance and unnecessary code. Starting now, we should allow free(NULL) even when built with the memdebug system enabled. free(NULL) is permitted by POSIX
2013-12-25Curl_thread_create: use Curl_safefree to allow NULL betterDaniel Stenberg
free() itself allows a NULL input but our memory debug system requires Curl_safefree() to be used instead when a "legitimate" NULL may be freed. Like in the code here. Pointed-out-by: Steve Holme
2013-12-25threaded resolver: Use pthread_t * for curl_thread_tLuke Dashjr
... since pthread_t may be non-scalar and/or may represent a real thread with scalar 0. Bug: http://curl.haxx.se/bug/view.cgi?id=1314
2013-12-24imap: Fixed auth preference not being honored when CAPABILITY not supportedSteve Holme
If a user indicated they preferred to authenticate using a SASL mechanism, but SASL authentication wasn't supported by the server, curl would always fall back to clear text when CAPABILITY wasn't supported, even though the user didn't want to use this.
2013-12-24pop3: Fixed auth preference not being honored when CAPA not supportedSteve Holme
If a user indicated they preferred to authenticate using APOP or a SASL mechanism, but neither were supported by the server, curl would always fall back to clear text when CAPA wasn't supported, even though the user didn't want to use this. This also fixes the auto build failure caused by commit 6f2d5f0562f64a.
2013-12-24Curl_pp_readresp: use memmove not memcpy, possibly overlapping areasDaniel Stenberg
Fixes commit 1deac31eba7
2013-12-24pop3: Fixed APOP being determined by CAPA response rather than by timestampSteve Holme
This commit replaces that of 9f260b5d6610f3 because according to RFC-2449, section 6, there is no APOP capability "...even though APOP is an optional command in [POP3]. Clients discover server support of APOP by the presence in the greeting banner of an initial challenge enclosed in angle brackets."
2013-12-22FILE: don't wait due to CURLOPT_MAX_RECV_SPEED_LARGEDaniel Stenberg
The FILE:// code doesn't support this option - and it doesn't make sense to support it as long as it works as it does since then it'd only block even longer. But: setting CURLOPT_MAX_RECV_SPEED_LARGE would make the transfer first get done and then libcurl would wait until the average speed would get low enough. This happened because the transfer happens completely in the DO state for FILE:// but then it would still unconditionally continue in to the PERFORM state where the speed check is made. Starting now, the code will skip from DO_DONE to DONE immediately if no socket is set to be recv()ed or send()ed to. Bug: http://curl.haxx.se/bug/view.cgi?id=1312 Reported-by: Mohammad AlSaleh

2013-12-22Curl_pp_readresp: replace stupid loop with memcpyDaniel Stenberg
2013-12-22Curl_pp_readresp: zero terminate lineDaniel Stenberg
The comment in the code mentions the zero terminating after having copied data, but it mistakingly zero terminated the source data and not the destination! This caused the test 864 problem discussed on the list: http://curl.haxx.se/mail/lib-2013-12/0113.html Signed-off-by: Daniel Stenberg <daniel@haxx.se>
2013-12-21Revert "pop3: Added debug information to assist with test864 failure"Steve Holme
This reverts commit 727d798d680f29c8b3cb7d7f03d6b6a3eb4356da.

2013-12-20pop3: Fixed selection of APOP when server replies with an invalid timestampSteve Holme
Although highlighted by a bug in commit 1cfb436a2f1795, APOP authentication could be chosen if the server was to reply with an empty or missing timestamp in the server greeting and APOP was given in the capability list by the server.
2013-12-20pop3: Fixed processing of more than one response when sent in same packetSteve Holme
Added a loop to pop3_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.
2013-12-19pop3: Moved CAPA response handling to pop3_state_capa_resp()Steve Holme
Similar to the processing of untagged CAPABILITY responses in IMAP and multi-line EHLO responses in SMTP, moved the processing of multi-line CAPA responses to pop3_state_capa_resp().
2013-12-19pop3: Moved APOP detection into pop3_state_servergreet_resp()Steve Holme
In an effort to reduce what pop3_endofresp() does and bring the POP3 source back inline with the IMAP and SMTP protocols, moved the APOP detection into pop3_state_servergreet_resp().
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.

2013-12-16gtls: respect *VERIFYHOST independently of *VERIFYPEERDaniel Stenberg
Security flaw CVE-2013-6422 This is conceptually the same problem and fix that 3c3622b6 brought to the OpenSSL backend and that resulted in CVE-2013-4545. This version of the problem was independently introduced to the GnuTLS backend with commit 59cf93cc, present in the code since the libcurl 7.21.4 release. Advisory: http://curl.haxx.se/docs/adv_20131217.html Bug: http://curl.haxx.se/mail/lib-2013-11/0214.html Reported-by: Marc Deslauriers
2013-12-15multi: add timer inaccuracy margin to timeout/connecttimeoutDaniel Stenberg
Since all systems have inaccuracy in the timeout handling it is imperative that we add an inaccuracy margin to the general timeout and connecttimeout handling with the multi interface. This way, when the timeout fires we should be fairly sure that it has passed the timeout value and will be suitably detected. For cases where the timeout fire before the actual timeout, we would otherwise consume the timeout action and still not run the timeout code since the condition wasn't met.

2013-12-14login options: remove the ;[options] support from CURLOPT_USERPWDDaniel Stenberg
To avoid the regression when users pass in passwords containing semi- colons, we now drop the ability to set the login options with the same options. Support for login options in CURLOPT_USERPWD was added in 7.31.0. Test case 83 was modified to verify that colons and semi-colons can be used as part of the password when using -u (CURLOPT_USERPWD).

2013-12-14imap: Fixed exclude of clear text when using auth=* in commit 75cd7fd66762bbSteve Holme
It is not 100% clear whether * should include clear text LOGIN or not from RFC-5092, however, including it is then consistent with current POP3 behaviour where clear text, APOP or SASL may be chosen.
2013-12-13imap: Fixed incorrect fallback to clear text authenticationSteve Holme
If a specific SASL authentication mechanism was requested by the user as part of the login options but wasn't supported by the server then curl would fallback to clear text, when it shouldn't, rather than reporting "No known authentication mechanisms supported" as the POP3 and SMTP protocols do.
2013-12-11parsedate: avoid integer overflowEric Lubin
In C, signed integer overflow is undefined behavior. Thus, the compiler is allowed to assume that it will not occur. In the check for an overflow, the developer assumes that the signed integer of type time_t will wrap around if it overflows. However, this behavior is undefined in the C standard. Thus, when the compiler sees this, it simplifies t + delta < t to delta < 0. Since delta > 0 and delta < 0 can't both be true, the entire if statement is optimized out under certain optimization levels. Thus, the parsedate function would return PARSEDATE_OK with an undefined value in the time, instead of return -1 = PARSEDATE_FAIL.
2013-12-07TFTP: let tftp_multi_statemach()'s return codes throughJames Dury
It would otherwise always clobber the return code with new function calls and it couldn't return timeout etc. Bug: http://curl.haxx.se/bug/view.cgi?id=1310
2013-12-07darwinssl: Fix #if 10.6.0 for SecKeychainSearchMelissa Mears
The comment here says that SecKeychainSearch causes a deprecation warning when used with a minimum Mac OS X SDK version of 10.7.0, which is correct. However, the #if guard did not match. It was intended to only use the code if 10.6.0 support was enabled, but it had 10.7.0 instead. This caused a warning if the minimum was exactly 10.7.0.
2013-12-04digest: fix CURLAUTH_DIGEST_IEDaniel Stenberg
The URI that is passed in as part of the Authorization: header needs to be cut off at '?' if CURLAUTH_DIGEST_IE is set. Previously the code only did when calculating the MD5sum. Bug: http://curl.haxx.se/bug/view.cgi?id=1308 Patched-by: Sergey Tatarincev

2013-12-04pop3: Fix POP3_TYPE_ANY signed compilation warningMelissa Mears
POP3_TYPE_ANY, or ~0, is written to pop3c->preftype in lib/pop3c.c, an unsigned int variable. The result of ~0 is -1, which caused a warning due to writing a negative number to an unsigned variable. To fix this, make the expression ~0U so that its value is considered the unsigned number UINT_MAX which is what SASL_AUTH_ANY does in curl_sasl.h.
