2015-06-15security:choose_mech fix DEAD CODE warningDaniel Stenberg
... by removing the "do {} while (0)" block. Coverity CID 1306669
2015-06-14urldata: store POST size in state.infilesize tooDaniel Stenberg
... to simplify checking when PUT _or_ POST have completed. Reported-by: Frank Meier Bug: http://curl.haxx.se/mail/lib-2015-06/0019.html
2015-06-11schannel: Add support for optional client certificatesJoel Depooter
Some servers will request a client certificate, but not require one. This change allows libcurl to connect to such servers when using schannel as its ssl/tls backend. When a server requests a client certificate, libcurl will now continue the handshake without one, rather than terminating the handshake. The server can then decide if that is acceptable or not. Prior to this change, libcurl would terminate the handshake, reporting a SEC_I_INCOMPLETE_CREDENTIALS error.
2015-06-10debug: remove http2 debug leftoversDaniel Stenberg
2015-06-09INTERNALS: cat lib/README* >> INTERNALSDaniel Stenberg
and a conversion to markdown. Removed the lib/README.* files. The idea being to move toward having INTERNALS as the one and only "book" of internals documentation. Added a TOC to top of the document.
2015-06-08openssl: LibreSSL and BoringSSL do not use TLS_client_methodJay Satiro
Although OpenSSL 1.1.0+ deprecated SSLv23_client_method in favor of TLS_client_method LibreSSL and BoringSSL didn't and still use SSLv23_client_method. Bug: https://github.com/bagder/curl/commit/49a6642#commitcomment-11578009 Reported-by: asavah@users.noreply.github.com
2015-06-09CURLOPT_OPENSOCKETFUNCTION: return error at onceDaniel Stenberg
When CURL_SOCKET_BAD is returned in the callback, it should be treated as an error (CURLE_COULDNT_CONNECT) if no other socket is subsequently created when trying to connect to a server. Bug: http://curl.haxx.se/mail/lib-2015-06/0047.html
2015-06-07openssl: Fix verification of server-sent legacy intermediatesJay Satiro
- Try building a chain using issuers in the trusted store first to avoid problems with server-sent legacy intermediates. Prior to this change server-sent legacy intermediates with missing legacy issuers would cause verification to fail even if the client's CA bundle contained a valid replacement for the intermediate and an alternate chain could be constructed that would verify successfully. https://rt.openssl.org/Ticket/Display.html?id=3621&user=guest&pass=guest
2015-06-05openssl: removed error string #ifdefDaniel Stenberg
ERR_error_string_n() was introduced in 0.9.6, no need to #ifdef anymore
2015-06-05openssl: removed USERDATA_IN_PWD_CALLBACK kludgeDaniel Stenberg
Code for OpenSSL 0.9.4 serves no purpose anymore!
2015-06-05openssl: remove SSL_get_session()-using codeDaniel Stenberg
It was present for OpenSSL 0.9.5 code but we only support 0.9.7 or later.
2015-06-05openssl: remove dummy callback use from SSL_CTX_set_verify()Daniel Stenberg
The existing callback served no purpose.
2015-06-03cookie: Stop exporting any-domain cookiesJay Satiro
Prior to this change any-domain cookies (cookies without a domain that are sent to any domain) were exported with domain name "unknown". Bug: https://github.com/bagder/curl/issues/292
2015-06-02curl_setup: Change fopen text macros to use 't' for MSDOSJay Satiro

2015-06-02checksrc: detect fopen() for text without the FOPEN_* macrosDaniel Stenberg
Follow-up to e8423f9ce150 with discussionis in https://github.com/bagder/curl/pull/258 This check scans for fopen() with a mode string without 'b' present, as it may indicate that an FOPEN_* define should rather be used.
2015-06-01curl_setup: Add macros for FOPEN_READTEXT, FOPEN_WRITETEXTJay Satiro
- Change fopen calls to use FOPEN_READTEXT instead of "r" or "rt" - Change fopen calls to use FOPEN_WRITETEXT instead of "w" or "wt" This change is to explicitly specify when we need to read/write text. Unfortunately 't' is not part of POSIX fopen so we can't specify it directly. Instead we now have FOPEN_READTEXT, FOPEN_WRITETEXT. Prior to this change we had an issue on Windows if an application that uses libcurl overrides the default file mode to binary. The default file mode in Windows is normally text mode (translation mode) and that's what libcurl expects.

2015-05-27openssl: Use TLS_client_method for OpenSSL 1.1.0+Jay Satiro
SSLv23_client_method is deprecated starting in OpenSSL 1.1.0. The equivalent is TLS_client_method. https://github.com/openssl/openssl/commit/13c9bb3#diff-708d3ae0f2c2973b272b811315381557
2015-05-25http2: Copy data passed in Curl_http2_switched into HTTP/2 connection bufferTatsuhiro Tsujikawa
Previously, after seeing upgrade to HTTP/2, we feed data followed by upgrade response headers directly to nghttp2_session_mem_recv() in Curl_http2_switched(). But it turns out that passed buffer, mem, is part of stream->mem, and callbacks called by nghttp2_session_mem_recv() will write stream specific data into stream->mem, overwriting input data. This will corrupt input, and most likely frame length error is detected by nghttp2 library. The fix is first copy the passed data to HTTP/2 connection buffer, httpc->inbuf, and call nghttp2_session_mem_recv().
2015-05-24conncache: fixed memory leak on OOM (torture tests)Dan Fandrich
2015-05-22security: fix "Unchecked return value" from sscanf()Daniel Stenberg
By (void) prefixing it and adding a comment. Did some minor related cleanups. Coverity CID 1299423.
2015-05-22security: simplify choose_mechDaniel Stenberg
Coverity CID 1299424 identified dead code because of checks that could never equal true (if the mechanism's name was NULL). Simplified the function by removing a level of pointers and removing the loop and array that weren't used.
2015-05-22RTSP: catch attempted unsupported requests betterDaniel Stenberg
Replace use of assert with code that properly catches bad input at run-time even in non-debug builds. This flaw was sort of detected by Coverity CID 1299425 which claimed the "case RTSPREQ_NONE" was dead code.
2015-05-22share_init: fix OOM crashDaniel Stenberg
A failed calloc() would lead to NULL pointer use. Coverity CID 1299427.
2015-05-22parse_proxy: switch off tunneling if non-HTTP proxyDaniel Stenberg
non-HTTP proxy implies not using CURLOPT_HTTPPROXYTUNNEL Bug: http://curl.haxx.se/mail/lib-2015-05/0056.html Reported-by: Sean Boudreau
2015-05-22http2: on_frame_recv: return early on stream 0Daniel Stenberg
Coverity CID 1299426 warned about possible NULL dereference otherwise, but that would only ever happen if we get invalid HTTP/2 data with frames for stream 0. Avoid this risk by returning early when stream 0 is used.
2015-05-22http: removed self assignmentDaniel Stenberg
Follow-up fix from b0143a2a33f0 Detected by coverity. CID 1299429
2015-05-22http2: Make HTTP Upgrade workTatsuhiro Tsujikawa
This commit just add implicitly opened stream 1 to streams hash.
2015-05-22strerror: Change SEC_E_ILLEGAL_MESSAGE descriptionJay Satiro
Prior to this change the description for SEC_E_ILLEGAL_MESSAGE was OS and language specific, and invariably translated to something not very helpful like: "The message received was unexpected or badly formatted." Bug: https://github.com/bagder/curl/issues/267 Reported-by: Michael Osipov
2015-05-21telnet: Fix read-callback change for Windows buildsJay Satiro
Refer to b0143a2 for more information on the read-callback change.
2015-05-20read_callback: move to SessionHandle from connectdataDaniel Stenberg
With many easy handles using the same connection for multiplexing, it is important we store and keep the transfer-oriented stuff in the SessionHandle so that callbacks and callback data work fine even when many easy handles share the same physical connection.
2015-05-20http2: show stream IDs in decimalDaniel Stenberg
It makes them easier to match output from the nghttpd test server.
2015-05-20http2: Faster http2 uploadTatsuhiro Tsujikawa
Previously, when we send all given buffer in data_source_callback, we return NGHTTP2_ERR_DEFERRED, and nghttp2 library removes this stream temporarily for writing. This itself is good. If this is the sole stream in the session, nghttp2_session_want_write() returns zero, which means that libcurl does not check writeability of the underlying socket. This leads to very slow upload, because it seems curl only upload 16k something per 1 second. To fix this, if we still have data to send, call nghttp2_session_resume_data after nghttp2_session_send. This makes nghttp2_session_want_write() returns nonzero (if connection window still opens), and as a result, socket writeability is checked, and upload speed becomes normal.
2015-05-20gtls: don't fail on non-fatal alerts during handshakeDmitry Eremin-Solenikov
Stop curl from failing when non-fatal alert is received during handshake. This e.g. fixes lots of problems when working with https sites through proxies.
2015-05-19openssl: Use SSL_CTX_set_msg_callback and SSL_CTX_set_msg_callback_argBrian Prodoehl
BoringSSL removed support for direct callers of SSL_CTX_callback_ctrl and SSL_CTX_ctrl, so move to a way that should work on BoringSSL and OpenSSL. re #275
2015-05-19transfer: remove erroneous and misleading commentDaniel Stenberg
2015-05-19http: silence compile-time warnings without USE_NGHTTP2Kamil Dudka
Error: CLANG_WARNING: lib/http.c:173:16: warning: Value stored to 'http' during its initialization is never read Error: COMPILER_WARNING: lib/http.c: scope_hint: In function ‘http_disconnect’ lib/http.c:173:16: warning: unused variable ‘http’ [-Wunused-variable]
2015-05-19transfer: Replace __func__ instances with function nameJay Satiro
.. also make __func__ replacement in multi. Prior to this change debug builds would fail to build if the compiler was building pre-c99 and didn't support __func__.
2015-05-19build: bump version in default nghttp2 pathsViktor Szakats
2015-05-18http: Add some include guards for the new HTTP/2 stuffJay Satiro
2015-05-18http2: store upload state per streamDaniel Stenberg
Use a curl_off_t for upload left
2015-05-18http2: fix build when NOT h2-enabledDaniel Stenberg
2015-05-18http2: switch to use Curl_hash_destroy()Daniel Stenberg
as after 4883f7019d3, the *_clean() function only flushes the hash.
2015-05-18hostip: fix unintended destruction of hash tableAnthony Avina
.. and added unit1602 for hash.c
2015-05-18http2: Ignore if we have stream ID not in hash in on_stream_closeTatsuhiro Tsujikawa
We could get stream ID not in the hash in on_stream_close. For example, if we decided to reject stream (e.g., PUSH_PROMISE), then we don't create stream and store it in hash with its stream ID.
2015-05-18Require nghttp2 v1.0.0Tatsuhiro Tsujikawa
This commit requires nghttp2 v1.0.0 to compile, and migrate to v1.0.0, and utilize recent version of nghttp2 to simplify the code, First we use nghttp2_option_set_no_recv_client_magic function to detect nghttp2 v1.0.0. That function only exists since v1.0.0. Since nghttp2 v0.7.5, nghttp2 ensures header field ordering, and validates received header field. If it found error, RST_STREAM with PROTOCOL_ERROR is issued. Since we require v1.0.0, we can utilize this feature to simplify libcurl code. This commit does this. Migration from 0.7 series are done based on nghttp2 migration document. For libcurl, we removed the code sending first 24 bytes client magic. It is now done by nghttp2 library. on_invalid_frame_recv callback signature changed, and is updated accordingly.
