2016-10-08formpost: avoid silent snprintf() truncationDaniel Stenberg
The previous use of snprintf() could make libcurl silently truncate some input data and not report that back on overly large input, which could make data get sent over the network in a bad format. Example: $ curl --form 'a=b' -H "Content-Type: $(perl -e 'print "A"x4100')"
2016-10-04memdup: use 'void *' as return and source typeDaniel Stenberg
2016-10-04formpost: trying to attach a directory no longer crashesDaniel Stenberg
The error path would previously add a freed entry to the linked list. Reported-by: Toby Peterson Fixes #1053
2016-10-03cookies: same domain handling changed to match browser behaviorSergei Kuzmin
Cokie with the same domain but different tailmatching property are now considered different and do not replace each other. If header contains following lines then two cookies will be set: Set-Cookie: foo=bar; domain=.foo.com; expires=Thu Mar 3 GMT 8:56:27 2033 Set-Cookie: foo=baz; domain=foo.com; expires=Thu Mar 3 GMT 8:56:27 2033 This matches Chrome, Opera, Safari, and Firefox behavior. When sending stored tokens to foo.com Chrome, Opera, Firefox store send them in the stored order, while Safari pre-sort the cookies. Closes #1050
2016-09-22New libcurl option to keep sending on errorMichael Kaufmann
Add the new option CURLOPT_KEEP_SENDING_ON_ERROR to control whether sending the request body shall be completed when the server responds early with an error status code. This is suitable for manual NTLM authentication. Reviewed-by: Jay Satiro Closes https://github.com/curl/curl/pull/904
2016-09-22nss: add chacha20-poly1305 cipher suites if supported by NSSKamil Dudka
2016-09-22nss: add cipher suites using SHA384 if supported by NSSKamil Dudka
2016-09-22nss: fix typo in ecdhe_rsa_null cipher suite stringKamil Dudka
As it seems to be a rarely used cipher suite (for securely established but _unencrypted_ connections), I believe it is fine not to provide an alias for the misspelled variant.

2016-09-19libressl: fix version outputBernard Spil
LibreSSL defines `OPENSSL_VERSION_NUMBER` as `0x20000000L` for all versions returning `LibreSSL/2.0.0` for any LibreSSL version. This change provides a local OpenSSL_version_num function replacement returning LIBRESSL_VERSION_NUMBER instead. Closes #1029

Follow-up fix to d9321562
2016-09-19openssl: don’t call CRYTPO_cleanup_all_ex_dataDaniel Stenberg
The OpenSSL function CRYTPO_cleanup_all_ex_data() cannot be called multiple times without crashing - and other libs might call it! We basically cannot call it without risking a crash. The function is a no-op since OpenSSL 1.1.0. Not calling this function only risks a small memory leak with OpenSSL < 1.1.0. Bug: https://curl.haxx.se/mail/lib-2016-09/0045.html Reported-by: Todd Short
2016-09-18darwinssl: disable RC4 cipher-suite supportNick Zitzmann
RC4 was a nice alternative to CBC back in the days of BEAST, but it's insecure and obsolete now.
2016-09-16http2: debug ouput sent HTTP/2 request headersDaniel Stenberg
2016-09-16http: accept "Transfer-Encoding: chunked" for HTTP/2 as wellDaniel Stenberg
... but don't send the actual header over the wire as it isn't accepted. Chunked uploading is still triggered using this method. Fixes #1013 Fixes #662
2016-09-14openssl: fix per-thread memory leak usiong 1.0.1 or 1.0.2Daniel Stenberg
OpenSSL 1.0.1 and 1.0.2 build an error queue that is stored per-thread so we need to clean it when easy handles are freed, in case the thread will be killed in which the easy handle was used. All OpenSSL code in libcurl should extract the error in association with the error already so clearing this queue here should be harmless at worst. Fixes #964

2016-09-12mbedtls: switch off NTLM in build if md4 isn't availableTony Kelman
NTLM support with mbedTLS was added in 497e7c9 but requires that mbedTLS is built with the MD4 functions available, which it isn't in default builds. This now adapts if the funtion isn't there and builds libcurl without NTLM support if so. Fixes #1004
2016-09-11http: refuse to pass on response body with NO_NODY was setDaniel Stenberg
... like when a HTTP/0.9 response comes back without any headers at all and just a body this now prevents that body from being sent to the callback etc. Adapted test 1144 to verify. Fixes #973 Assisted-by: Ray Satiro
2016-09-10CMake: Try to (un-)hide private library symbolsJakub Zakrzewski
Detect support for compiler symbol visibility flags and apply those according to CURL_HIDDEN_SYMBOLS option. It should work true to the autotools build except it tries to unhide symbols on Windows when requested and prints warning if it fails.

2016-09-09openssl: fix bad memory free (regression)Daniel Stenberg
... by partially reverting f975f06033b1. The allocation could be made by OpenSSL so the free must be made with OPENSSL_free() to avoid problems. Reported-by: Harold Stuart Fixes #1005
2016-09-09http2: support > 64bit sized uploadsDaniel Stenberg
... by making sure we don't count down the "upload left" counter when the uploaded size is unknown and then it can be allowed to continue forever. Fixes #996
2016-09-07errors: new alias CURLE_WEIRD_SERVER_REPLY (8)Jay Satiro
Since we're using CURLE_FTP_WEIRD_SERVER_REPLY in imap, pop3 and smtp as more of a generic "failed to parse" introduce an alias without FTP in the name. Closes https://github.com/curl/curl/pull/975

2016-09-07mk-ca-bundle.pl: use SHA256 instead of SHA1Viktor Szakats
This hash is used to verify the original downloaded certificate bundle and also included in the generated bundle's comment header. Also rename related internal symbols to algorithm-agnostic names.
2016-09-06openssl: fix CURLINFO_SSL_VERIFYRESULTGaurav Malhotra
CURLINFO_SSL_VERIFYRESULT does not get the certificate verification result when SSL_connect fails because of a certificate verification error. This fix saves the result of SSL_get_verify_result so that it is returned by CURLINFO_SSL_VERIFYRESULT. Closes https://github.com/curl/curl/pull/995
2016-09-06darwinssl: test for errSecSuccess in PKCS12 import rather than noErr (#993)Daniel Gustafsson
While noErr and errSecSuccess are defined as the same value, the API documentation states that SecPKCS12Import() returns errSecSuccess if there were no errors in importing. Ensure that a future change of the defined value doesn't break (however unlikely) and be consistent with the API docs.
2016-09-05openssl: Fix compilation with OPENSSL_API_COMPAT=0x10100000LMarcel Raad
With OPENSSL_API_COMPAT=0x10100000L (OpenSSL 1.1 API), the cleanup functions are unavailable (they're no-ops anyway in OpenSSL 1.1). The replacements for SSL_load_error_strings, SSLeay_add_ssl_algorithms, and OpenSSL_add_all_algorithms are called automatically [1][2]. SSLeay() is now called OpenSSL_version_num(). [1]: https://www.openssl.org/docs/man1.1.0/ssl/OPENSSL_init_ssl.html [2]: https://www.openssl.org/docs/man1.1.0/crypto/OPENSSL_init_crypto.html Closes #992

2016-09-04speed caps: not based on average speeds anymoreOlivier Brunel
Speed limits (from CURLOPT_MAX_RECV_SPEED_LARGE & CURLOPT_MAX_SEND_SPEED_LARGE) were applied simply by comparing limits with the cumulative average speed of the entire transfer; While this might work at times with good/constant connections, in other cases it can result to the limits simply being "ignored" for more than "short bursts" (as told in man page). Consider a download that goes on much slower than the limit for some time (because bandwidth is used elsewhere, server is slow, whatever the reason), then once things get better, curl would simply ignore the limit up until the average speed (since the beginning of the transfer) reached the limit. This could prove the limit useless to effectively avoid using the entire bandwidth (at least for quite some time). So instead, we now use a "moving starting point" as reference, and every time at least as much as the limit as been transferred, we can reset this starting point to the current position. This gets a good limiting effect that applies to the "current speed" with instant reactivity (in case of sudden speed burst). Closes #971

2016-08-28http2: make sure stream errors don't needlessly close the connectionDaniel Stenberg
With HTTP/2 each transfer is made in an indivial logical stream over the connection, making most previous errors that caused the connection to get forced-closed now instead just kill the stream and not the connection. Fixes #941
2016-08-27Curl_verify_windows_version: minor edit to avoid compiler warningsDaniel Stenberg
... instead of if() before the switch(), add a default to the switch so that the compilers don't warn on "warning: enumeration value 'PLATFORM_DONT_CARE' not handled in switch" anymore.
2016-08-26schannel: Disable ALPN for Wine since it is causing problemsJay Satiro
- Disable ALPN on Wine. - Don't pass input secbuffer when ALPN is disabled. When ALPN support was added a change was made to pass an input secbuffer to initialize the context. When ALPN is enabled the buffer contains the ALPN information, and when it's disabled the buffer is empty. In either case this input buffer caused problems with Wine and connections would not complete. Bug: https://github.com/curl/curl/issues/983 Reported-by: Christian Fillion
2016-08-26nss: work around race condition in PK11_FindSlotByName()Peter Wang

2016-08-23ftp: fix wrong poll on the secondary socketAles Novak
When we're uploading using FTP and the server issues a tiny pause between opening the connection to the client's secondary socket, the client's initial poll() times out, which leads to second poll() which does not wait for POLLIN on the secondary socket. So that poll() also has to time out, creating a long (200ms) pause. This patch adds the correct flag to the secondary socket, making the second poll() correctly wait for the connection there too. Signed-off-by: Ales Novak <alnovak@suse.cz> Closes #978
