2016-08-05http2: always wait for readable socketDaniel Stenberg
Since the server can at any time send a HTTP/2 frame to us, we need to wait for the socket to be readable during all transfers so that we can act on incoming frames even when uploading etc. Reminded-by: Tatsuhiro Tsujikawa
2016-08-05mbedtls: set debug threshold to 4 (verbose) when MBEDTLS_DEBUG is definedThomas Glanzmann
In order to make MBEDTLS_DEBUG work, the debug threshold must be unequal to 0. This patch also adds a comment how mbedtls must be compiled in order to make debugging work, and explains the possible debug levels.
2016-08-05CURLOPT_TCP_NODELAY: now enabled by defaultDaniel Stenberg
After a few wasted hours hunting down the reason for slowness during a TLS handshake that turned out to be because of TCP_NODELAY not being set, I think we have enough motivation to toggle the default for this option. We now enable TCP_NODELAY by default and allow applications to switch it off. This also makes --tcp-nodelay unnecessary, but --no-tcp-nodelay can be used to disable it. Thanks-to: Tim Rühsen Bug: https://curl.haxx.se/mail/lib-2016-06/0143.html
2016-08-04TFTP: Fix upload problem with piped inputSerj Kalichev
When input stream for curl is stdin and input stream is not a file but generated by a script then curl can truncate data transfer to arbitrary size since a partial packet is treated as end of transfer by TFTP. Fixes #857
2016-08-04mk-ca-bundle.pl: -m keeps ca cert meta data in outputDaniel Stenberg
Makes the script pass on comments holding meta data to the output file. Like fingerprinters, issuer, date ranges etc. Closes #937
2016-08-04multi: make Curl_expire() work with 0 ms timeoutsDaniel Stenberg
Previously, passing a timeout of zero to Curl_expire() was a magic code for clearing all timeouts for the handle. That is now instead made with the new Curl_expire_clear() function and thus a 0 timeout is fine to set and will trigger a timeout ASAP. This will help removing short delays, in particular notable when doing HTTP/2.
2016-08-04transfer: return without select when the read loop reached maxcountDaniel Stenberg
Regression added in 790d6de48515. The was then added to avoid one particular transfer to starve out others. But when aborting due to reading the maxcount, the connection must be marked to be read from again without first doing a select as for some protocols (like SFTP/SCP) the data may already have been read off the socket.

2016-08-01mbedtls: Fix debug function nameThomas Glanzmann
This patch is necessary so that curl compiles if MBEDTLS_DEBUG is defined. Bug: https://curl.haxx.se/mail/lib-2016-08/0001.html
2016-08-01win32: fix a potential memory leak in Curl_load_libraryMartin Vejnár
If a call to GetSystemDirectory fails, the `path` pointer that was previously allocated would be leaked. This makes sure that `path` is always freed. Closes #938
2016-07-23vauth.h: No need to query HAVE_GSSAPI || USE_WINDOWS_SSPI for SPNEGOSteve Holme
As SPNEGO is only defined when these pre-processor variables are defined there is no need to query them explicitly.
2016-07-23spnego: Corrected miss-placed * in Curl_auth_spnego_cleanup() declarationSteve Holme
Typo introduced in commit ad5e9bfd5d.
2016-07-20vauth: Fix memleak by freeing credentials if out of memoryJay Satiro
This is a follow up to the parent commit dcdd4be which fixes one leak but creates another by failing to free the credentials handle if out of memory. Also there's a second location a few lines down where we fail to do same. This commit fixes both of those issues.
2016-07-20vauth: Fixed memory leak due to function returning without freeSaurav Babu
This patch allocates memory to "output_token" only when it is required so that memory is not leaked if function returns.

2016-07-18curl_global_init: Check if IPv6 worksBrian Prodoehl
- Curl_ipv6works() is not thread-safe until after the first call, so call it once during global init to avoid a possible race condition. Bug: https://github.com/curl/curl/issues/915 PR: https://github.com/curl/curl/pull/918

2016-06-28cleanup: minor code cleanup in Curl_http_readwrite_headers()Michael Kaufmann
- the expression of an 'if' was always true - a 'while' contained a condition that was always true - use 'if(k->exp100 > EXP100_SEND_DATA)' instead of 'if(k->exp100)' - fixed a typo Closes #889
2016-06-28SFTP: set a generic error when no SFTP one exists...Daniel Stenberg
... as otherwise we could get a 0 which would count as no error and we'd wrongly continue and could end up segfaulting. Bug: https://curl.haxx.se/mail/lib-2016-06/0052.html Reported-by: 暖和的和暖

2016-06-22vc: fix the build for schannel certinfo supportDaniel Stenberg
Broken since 6cabd785, which adds use of the Curl_extract_certinfo function from the x509asn1.c file.
2016-06-22typedefs: use the full structs in internal code...Daniel Stenberg

2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-06-22vtls: Only call add/getsession if session id is enabledJay Satiro
Prior to this change we called Curl_ssl_getsessionid and Curl_ssl_addsessionid regardless of whether session ID reusing was enabled. According to comments that is in case session ID reuse was disabled but then later enabled. The old way was not intuitive and probably not something users expected. When a user disables session ID caching I'd guess they don't expect the session ID to be cached anyway in case the caching is later enabled.

2016-06-07resolve: enable protocol family logic for synthesized IPv6Luo Jinghua
- Enable protocol family logic for IPv6 resolves even when support for synthesized addresses is enabled. This is a follow up to the parent commit that added support for synthesized IPv6 addresses from IPv4 on iOS/OS X. The protocol family logic needed for IPv6 was inadvertently excluded if support for synthesized addresses was enabled.

2016-06-07resolve: add support for IPv6 DNS64/NAT64 Networks on OS X + iOSLuo Jinghua
Use getaddrinfo() to resolve the IPv4 address literal on iOS/Mac OS X. If the current network interface doesn’t support IPv4, but supports IPv6, NAT64, and DNS64. Closes #866 Fixes #863
2016-06-06schannel: Disable ALPN on Windows < 8.1Steve Holme
Calling QueryContextAttributes with SECPKG_ATTR_APPLICATION_PROTOCOL fails on Windows < 8.1 so we need to disable ALPN on these OS versions. Inspiration provide by: Daniel Seither Closes #848 Fixes #840

LoadLibrary was supplanted by Curl_load_library for security reasons in 6df916d.
2016-06-05http: Fix HTTP/2 connection reuseJay Satiro
- Change the parser to not require a minor version for HTTP/2. HTTP/2 connection reuse broke when we changed from HTTP/2.0 to HTTP/2 in 8243a95 because the parser still expected a minor version. Bug: https://github.com/curl/curl/issues/855 Reported-by: Andrew Robbins, Frank Gevaerts

2016-06-01vtls: fix ssl session cache race conditionIvan Avdeev
Sessionid cache management is inseparable from managing individual session lifetimes. E.g. for reference-counted sessions (like those in SChannel and OpenSSL engines) every session addition and removal should be accompanied with refcount increment and decrement respectively. Failing to do so synchronously leads to a race condition that causes symptoms like use-after-free and memory corruption. This commit: - makes existing session cache locking explicit, thus allowing individual engines to manage lock's scope. - fixes OpenSSL and SChannel engines by putting refcount management inside this lock's scope in relevant places. - adds these explicit locking calls to other engines that use sessionid cache to accommodate for this change. Note, however, that it is unknown whether any of these engines could also have this race. Bug: https://github.com/curl/curl/issues/815 Fixes #815 Closes #847

2016-05-30URL parser: allow URLs to use one, two or three slashesDaniel Stenberg
Mostly in order to support broken web sites that redirect to broken URLs that are accepted by browsers. Browsers are typically even more leniant than this as the WHATWG URL spec they should allow an _infinite_ amount. I tested 8000 slashes with Firefox and it just worked. Added test case 1141, 1142 and 1143 to verify the new parser. Closes #791
