2012-11-18fixed memory leak: CURLOPT_RESOLVE with multi interfaceDaniel Stenberg
DNS cache entries populated with CURLOPT_RESOLVE were not properly freed again when done using the multi interface. Test case 1502 added to verify. Bug: http://curl.haxx.se/bug/view.cgi?id=3575448 Reported by: Alex Gruz
2012-11-17mem-include-scan: verify memory #includesDaniel Stenberg
If we use memory functions (malloc, free, strdup etc) in C sources in libcurl and we fail to include curl_memory.h or memdebug.h we either fail to properly support user-provided memory callbacks or the memory leak system of the test suite fails. After Ajit's report of a failure in the first category in http_proxy.c, I spotted a few in the second category as well. These problems are now tested for by test 1132 which runs a perl program that scans for and attempts to check that we use the correct include files if a memory related function is used in the source code. Reported by: Ajit Dhumale Bug: http://curl.haxx.se/mail/lib-2012-11/0125.html

It either causes increased memory usage or exposes users to the "CRIME attack" (CVE-2012-4929)

2012-11-12Digst: Add microseconds into nounce calculationGabriel Sjoberg
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.
2012-11-12SCP/SFTP: improve error code used for send failuresDaniel Stenberg
Instead of relying on the generic CURLE error for SCP or SFTP send failures, try passing back a more suitable error if possible.

2012-11-08SSL: Several SSL-backend related fixesOscar Koeroo
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.
2012-11-08libcurl: VERSIONINFO updateDaniel Stenberg
Since we added the curl_multi_wait function, the VERSIONINFO needed updating. Reported by: Patrick Monnerat
2012-11-08Added .def file to output.Guenter Knauf
Requested by Johnny Luong on the libcurl list.
2012-11-08Curl_readwrite: remove debug outputDaniel Stenberg
The text "additional stuff not fine" text was added for debug purposes a while ago, but it isn't really helping anyone and for some reason some Linux distributions provide their libcurls built with debug info still present and thus (far too many) users get to read this info.
2012-11-07http_perhapsrewind: consider NTLM over proxy tooDaniel Stenberg
The logic previously checked for a started NTLM negotiation only for host and not also with proxy, leading to problems doing POSTs over a proxy NTLM that are larger than 2000 bytes. Now it includes proxy in the check. Bug: http://curl.haxx.se/bug/view.cgi?id=3582321 Reported by: John Suprock
2012-11-07Curl_connecthost: friendlier "couldn't connect" messageLars Buitinck
2012-11-06URL parser: cut off '#' fragments from URLs (better)Daniel Stenberg
The existing logic only cut off the fragment from the separate 'path' buffer which is used when sending HTTP to hosts. The buffer that held the full URL used for proxies were not dealt with. It is now. Test case 5 was updated to use a fragment on a URL over a proxy. Bug: http://curl.haxx.se/bug/view.cgi?id=3579813
2012-11-06OpenSSL/servercert: use correct buffer size, not size of pointerDaniel Stenberg
Bug: http://curl.haxx.se/bug/view.cgi?id=3579286
2012-11-06Curl_pretransfer: clear out unwanted auth methodsDaniel Stenberg
As a handle can be re-used after having done HTTP auth in a previous request, it must make sure to clear out the HTTP types that aren't wanted in this new request.
2012-11-06Revert "Zero out auth structs before transfer"Daniel Stenberg
This reverts commit ce8311c7e49eca93c136b58efa6763853541ec97. The commit made test 2024 work but caused a regression with repeated Digest authentication. We need to fix this differently.
2012-11-06CURLOPT_SSL_VERIFYHOST: stop supporting the 1 valueDaniel Stenberg
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. [1] = http://daniel.haxx.se/blog/2012/10/25/libcurl-claimed-to-be-dangerous/

2012-11-06uniformly use AM_CPPFLAGS, avoid deprecated INCLUDESDave Reisner
Since automake 1.12.4, the warnings are issued on running automake: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS') Avoid INCLUDES and roll these flags into AM_CPPFLAGS.

2012-11-05ftp_readresp: fix build without krb4 supportDaniel Stenberg
Oops, my previous commit broke builds with krb support.
2012-11-04FTP: prevent the multi interface from blockingDaniel Stenberg
As pointed out in Bug report #3579064, curl_multi_perform() would wrongly use a blocking mechanism internally for some commands which could lead to for example a very long block if the LIST response never showed. The solution was to make sure to properly continue to use the multi interface non-blocking state machine. The new test 1501 verifies the fix. Bug: http://curl.haxx.se/bug/view.cgi?id=3579064 Reported by: Guido Berhoerster
2012-10-23tlsauthtype: deal with the string case insensitivelyDaniel Stenberg
When given a string as 'srp' it didn't work, but required 'SRP'. Starting now, the check disregards casing. Bug: http://curl.haxx.se/bug/view.cgi?id=3578418 Reported by: Jeff Connelly
2012-10-23asyn-ares: restore working with c-ares < 1.6.1Daniel Stenberg
Back in those days the public ares.h header didn't include the ares_version.h header so it needs to be included here. Bug: http://curl.haxx.se/bug/view.cgi?id=3577710
2012-10-22metalink/md5: Use CommonCrypto on Apple operating systemsNick Zitzmann
Previously the Metalink code used Apple's CommonCrypto library only if curl was built using the --with-darwinssl option. Now we use CommonCrypto on all Apple operating systems including Tiger or later, or iOS 5 or later, so you don't need to build --with-darwinssl anymore. Also rolled out this change to libcurl's md5 code.
2012-10-16darwinssl: un-broke iOS build, fix error on server disconnectNick Zitzmann
The iOS build was broken by a reference to a function that only existed under OS X; fixed. Also fixed a hard-to-reproduce problem where, if the server disconnected before libcurl got the chance to hang up first and SecureTransport was in use, then we'd raise an error instead of failing gracefully.

2012-10-09curl_multi_wait: no wait if no descriptors to wait forDaniel Stenberg
This is a minor change in behavior after having been pointed out by Mark Tully and discussed on the list. Initially this case would internally call poll() with no sockets and a timeout which would equal a sleep for that specified time. Bug: http://curl.haxx.se/mail/lib-2012-10/0076.html Reported by: Mark Tully
2012-10-08ssluse.c: md5.h is required for Curl_ossl_md5sumMarc Hoersken
2012-10-06curl_schannel.c: Fixed caching more data than requiredMarc Hoersken
Do not fill the decrypted data buffer with more data unless required in order to return the requested amount of data.
2012-10-06curl_schannel: Removed buffer limit and optimized buffer strategyMarc Hoersken
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.
2012-10-04lib/socks.c: Merged two size variables into oneMarc Hoersken
2012-10-04lib/socks.c: Avoid type conversions where possibleMarc Hoersken
Streamlined variable names and types to avoid type conversions that may result in data being lost on non 32-bit systems.

2012-10-04security.c: Aligned internal type to return typeMarc Hoersken
Use ssize_t instead of int to avoid conversion problems on 64-bit systems. Also added curlx_sztosi where necessary.
2012-10-03lib/curl_schannel: Increased maximum buffer size to factor 128Marc Hoersken
2012-10-02multi_runsingle: CURLOPT_LOW_SPEED_* fix for rate limitationDaniel Stenberg
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. Bug: http://curl.haxx.se/mail/lib-2012-09/0081.html Reported by: Jie He
2012-09-28Curl_reconnect_request: clear pointer on failureDaniel Stenberg
The Curl_reconnect_request() function could end up returning a pointer to a free()d struct when Curl_done() failed inside. Clearing the pointer unconditionally after Curl_done() avoids this risk. Reported by: Ho-chi Chen Bug: http://curl.haxx.se/mail/lib-2012-09/0188.html

Minor change to recently introduced function. BC breaking, but since curl_multi_wait() doesn't exist in any releases that should be fine.
