2018-01-14mime: clone mime tree upon easy handle duplication.Patrick Monnerat
A mime tree attached to an easy handle using CURLOPT_MIMEPOST is strongly bound to the handle: there is a pointer to the easy handle in each item of the mime tree and following the parent pointer list of mime items ends in a dummy part stored within the handle. Because of this binding, a mime tree cannot be shared between different easy handles, thus it needs to be cloned upon easy handle duplication. There is no way for the caller to get the duplicated mime tree handle: it is then set to be automatically destroyed upon freeing the new easy handle. New test 654 checks proper mime structure duplication/release. Add a warning note in curl_mime_data_cb() documentation about sharing user data between duplicated handles. Closes #2235
2018-01-13HTTP: bail out on negative Content-Length: valuesDaniel Stenberg
... and make the max filesize check trigger if the value is too big. Updates test 178. Reported-by: Brad Spencer Fixes #2212 Closes #2223
2018-01-13setopt: fix SSLVERSION to allow CURL_SSLVERSION_MAX_ valuesJay Satiro
Broken since f121575 (precedes 7.56.1). Bug: https://github.com/curl/curl/issues/2225 Reported-by: cmfrolick@users.noreply.github.com Closes https://github.com/curl/curl/pull/2227
2018-01-13setopt: reintroduce non-static Curl_vsetopt() for OS400 supportPatrick Monnerat
This also upgrades ILE/RPG bindings with latest setopt options. Reported-By: jonrumsey on github Fixes #2230 Closes #2233
2018-01-11http2: fix incorrect trailer buffer sizeZhouyihai Ding
Prior to this change the stored byte count of each trailer was miscalculated and 1 less than required. It appears any trailer after the first that was passed to Curl_client_write would be truncated or corrupted as well as the size. Potentially the size of some subsequent trailer could be erroneously extracted from the contents of that trailer, and since that size is used by client write an out-of-bounds read could occur and cause a crash or be otherwise processed by client write. The bug appears to have been born in 0761a51 (precedes 7.49.0). Closes https://github.com/curl/curl/pull/2231
2018-01-09easy: fix connection ownership in curl_easy_pauseBasuke Suzuki
Before calling Curl_client_chop_write(), change the owner of connection to the current Curl_easy handle. This will fix the issue #2217. Fixes https://github.com/curl/curl/issues/2217 Closes https://github.com/curl/curl/pull/2221
2018-01-08progress: calculate transfer speed on milliseconds if possibleDaniel Stenberg
to increase accuracy for quick transfers Fixes #2200 Closes #2206
2018-01-07scripts: allow all perl scripts to be run directlyJay Satiro
- Enable execute permission (chmod +x) - Change interpreter to /usr/bin/env perl Closes https://github.com/curl/curl/pull/2222
2018-01-05build: remove HAVE_LIMITS_H checkJay Satiro
.. because limits.h presence isn't optional, it's required by C89. Ref: http://port70.net/~nsz/c/c89/c89-draft.html#2.2.4.2 Closes https://github.com/curl/curl/pull/2215
2018-01-03openssl: fix memory leak of SSLKEYLOGFILE filenameJay Satiro
- Free the copy of SSLKEYLOGFILE env returned by curl_getenv during ossl initialization. Caught by ASAN.
2017-12-27brotli: data at the end of content can be lostMikalai Ananenka
Decoding loop implementation did not concern the case when all received data is consumed by Brotli decoder and the size of decoded data internally hold by Brotli decoder is greater than CURL_MAX_WRITE_SIZE. For content with unencoded length greater than CURL_MAX_WRITE_SIZE this can result in the loss of data at the end of content. Closes #2194
2017-12-20curl_easy_reset: release mime-related data.Patrick Monnerat
Move curl_mime_initpart() and curl_mime_cleanpart() calls to lower-level functions dealing with UserDefined structure contents. This avoids memory leakages on curl-generated part mime headers. New test 2073 checks this using the cli tool --next option: it triggers a valgrind error if bug is present. Bug: https://curl.haxx.se/mail/lib-2017-12/0060.html Reported-by: Martin Galvan
2017-12-20content_encoding: rework zlib_inflatePatrick Monnerat
- When zlib version is < 1.2.0.4, process gzip trailer before considering extra data as an error. - Inflate with Z_BLOCK instead of Z_SYNC_FLUSH to maximize correct data and minimize corrupt data output. - Do not try to restart deflate decompression in raw mode if output has started or if the leading data is not available anymore. - New test 232 checks inflating raw-deflated content. Closes #2068
2017-12-20brotli: allow compiling with version 0.6.0.Patrick Monnerat
Some error codes were not yet defined in brotli 0.6.0: do not issue code for them in this case.
2017-12-13rand: add a clang-analyzer work-aroundDaniel Stenberg
scan-build would warn on a potential access of an uninitialized buffer. I deem it a false positive and had to add this somewhat ugly work-around to silence it.

2017-12-12setopt: less *or equal* than INT_MAX/1000 should be fineDaniel Stenberg
... for the CURLOPT_TIMEOUT, CURLOPT_CONNECTTIMEOUT and CURLOPT_SERVER_RESPONSE_TIMEOUT range checks. Reported-by: Dominik Hölzl Bug: https://curl.haxx.se/mail/lib-2017-12/0037.html Closes #2173
2017-12-12vtls: replaced getenv() with curl_getenv()dmitrykos
Fixed undefined symbol of getenv() which does not exist when compiling for Windows 10 App (CURL_WINDOWS_APP). Replaced getenv() with curl_getenv() which is aware of getenv() absence when CURL_WINDOWS_APP is defined. Closes #2171
2017-12-10multi_done: prune DNS cacheDaniel Stenberg
Prune the DNS cache immediately after the dns entry is unlocked in multi_done. Timed out entries will then get discarded in a more orderly fashion. Test506 is updated Reported-by: Oleg Pudeyev Fixes #2169 Closes #2170
2017-12-10openssl: Disable file buffering for Win32 SSLKEYLOGFILEJay Satiro
Prior to this change SSLKEYLOGFILE used line buffering on WIN32 just like it does for other platforms. However, the Windows CRT does not actually support line buffering (_IOLBF) and will use full buffering (_IOFBF) instead. We can't use full buffering because multiple processes may be writing to the file and that could lead to corruption, and since full buffering is the only buffering available this commit disables buffering for Windows SSLKEYLOGFILE entirely (_IONBF).

2017-12-08curl: remove __EMX__ #ifdefsDaniel Stenberg
These are OS/2-specific things added to the code in the year 2000. They were always ugly. If there's any user left, they still don't need it done this way. Closes #2166
2017-12-08openssl: improve data-pending check for https proxyJay Satiro
- Allow proxy_ssl to be checked for pending data even when connssl does not yet have an SSL handle. This change is for posterity. Currently there doesn't seem to be a code path that will cause a pending data check when proxyssl could have pending data and the connssl handle doesn't yet exist [1]. [1]: Recall that an https proxy connection starts out in connssl but if the destination is also https then the proxy SSL backend data is moved from connssl to proxyssl, which means connssl handle is temporarily empty until an SSL handle for the destination can be created. Ref: https://github.com/curl/curl/commit/f4a6238#commitcomment-24396542 Closes https://github.com/curl/curl/pull/1916

2017-12-05conncache: only allow multiplexing within same multi handleDaniel Stenberg
Connections that are used for HTTP/1.1 Pipelining or HTTP/2 multiplexing only get additional transfers added to them if the existing connection is held by the same multi or easy handle. libcurl does not support doing HTTP/2 streams in different threads using a shared connection. Closes #2152
2017-12-05conncache: fix several lock issuesDaniel Stenberg
If the lock is released before the dealings with the bundle is over, it may have changed by another thread in the mean time. Fixes #2132 Fixes #2151 Closes #2139

2017-12-05sasl_getmesssage: make sure we have a long enough string to passDaniel Stenberg
For pop3/imap/smtp, added test 891 to somewhat verify the pop3 case. For this, I enhanced the pingpong test server to be able to send back responses with LF-only instead of always using CRLF. Closes #2150
2017-12-04libssh2: remove dead code from SSH_SFTP_QUOTEDaniel Stenberg
Figured out while reviewing code in the libssh backend. The pointer was checked for NULL after having been dereferenced, so we know it would always equal true or it would've crashed. Pointed-out-by: Nikos Mavrogiannopoulos Bug #2143 Closes #2148

2017-12-01lib: don't export all symbols, just everything curl_*W. Mark Kubacki
Absent any 'symbol map' or script to limit what gets exported, static linking of libraries previously resulted in a libcurl with curl's and those other symbols being (re-)exported. This did not happen if 'versioned symbols' were enabled (which is not the default) because then a version script is employed. This limits exports to everything starting in 'curl_*'., which is what "libcurl.vers" exports. This avoids strange side-effects such as with mixing methods from system libraries and those erroneously offered by libcurl. Closes #2127
2017-12-01SSL: Avoid magic allocation of SSL backend specific dataJohannes Schindelin
Originally, my idea was to allocate the two structures (or more precisely, the connectdata structure and the four SSL backend-specific strucutres required for ssl[0..1] and proxy_ssl[0..1]) in one go, so that they all could be free()d together. However, getting the alignment right is tricky. Too tricky. So let's just bite the bullet and allocate the SSL backend-specific data separately. As a consequence, we now have to be very careful to release the memory allocated for the SSL backend-specific data whenever we release any connectdata. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Closes #2119
2017-11-27openssl: fix boringssl build againDaniel Stenberg
commit d3ab7c5a21e broke the boringssl build since it doesn't have RSA_flags(), so we disable that code block for boringssl builds. Reported-by: W. Mark Kubacki Fixes #2117
