2018-03-22http2: read pending frames (including GOAWAY) in connection-checkDaniel Stenberg
If a connection has received a GOAWAY frame while not being used, the function now reads frames off the connection before trying to reuse it to avoid reusing connections the server has told us not to use. Reported-by: Alex Baines Fixes #1967 Closes #2402
2018-03-20vauth/cleartext: fix integer overflow checkDaniel Stenberg
Make the integer overflow check not rely on the undefined behavior that a size_t wraps around on overflow. Detected by lgtm.com Closes #2408
2018-03-20lib/curl_path.h: add #ifdef header guardDaniel Stenberg

2018-03-19parsedate: support UT timezoneNikos Tsipinakis
RFC822 section 5.2 mentions Universal Time, 'UT', to be synonymous with GMT. Closes #2401
2018-03-19cmake: add support for brotliDon
Currently CMake cannot detect Brotli support. This adds detection of the libraries and associated header files. It also adds this to the generated config. Closes #2392

2018-03-17resolve: add CURLOPT_DNS_SHUFFLE_ADDRESSESRick Deist
This patch adds CURLOPT_DNS_SHUFFLE_ADDRESSES to explicitly request shuffling of IP addresses returned for a hostname when there is more than one. This is useful when the application knows that a round robin approach is appropriate and is willing to accept the consequences of potentially discarding some preference order returned by the system's implementation. Closes #1694
2018-03-17add_handle/easy_perform: clear errorbuffer on start if setDaniel Stenberg
To offer applications a more defined behavior, we clear the buffer as early as possible. Assisted-by: Jay Satiro Fixes #2190 Closes #2377
2018-03-17CURLOPT_HAPROXYPROTOCOL: support the HAProxy PROXY protocolLawrence Matthews
Add --haproxy-protocol for the command line tool Closes #2162
2018-03-16multi: improved pending transfers handling => improved performanceDaniel Stenberg
When a transfer is requested to get done and it is put in the pending queue when limited by number of connections, total or per-host, libcurl would previously very aggressively retry *ALL* pending transfers to get them transferring. That was very time consuming. By reducing the aggressiveness in how pending are being retried, we waste MUCH less time on putting transfers back into pending again. Some test cases got a factor 30(!) speed improvement with this change. Reported-by: Cyril B Fixes #2369 Closes #2383
2018-03-16pause: when changing pause state, update socket stateDaniel Stenberg
Especially unpausing a transfer might have to move the socket back to the "currently used sockets" hash to get monitored. Otherwise it would never get any more data and get stuck. Easily triggered with pausing using the multi_socket API. Reported-by: Philip Prindeville Bug: https://curl.haxx.se/mail/lib-2018-03/0048.html Fixes #2393 Closes #2391
2018-03-16rate-limit: use three second window to better handle high speedsDaniel Stenberg
Due to very frequent updates of the rate limit "window", it could attempt to rate limit within the same milliseconds and that then made the calculations wrong, leading to it not behaving correctly on very fast transfers. This new logic updates the rate limit "window" to be no shorter than the last three seconds and only updating the timestamps for this when switching between the states TOOFAST/PERFORM. Reported-by: 刘佩东 Fixes #2386 Closes #2388

This reverts commit a577059f92fc65bd6b81717f0737f897a5b34248. The assignment really needs to be there or we risk working with an uninitialized pointer.

2018-03-12FTP: reject path components with control codesDaniel Stenberg
Refuse to operate when given path components featuring byte values lower than 32. Previously, inserting a %00 sequence early in the directory part when using the 'singlecwd' ftp method could make curl write a zero byte outside of the allocated buffer. Test case 340 verifies. CVE-2018-1000120 Reported-by: Duy Phan Thanh Bug: https://curl.haxx.se/docs/adv_2018-9cd6.html

2018-03-04krb5: use nondeprecated functionsMarcel Raad
gss_seal/gss_unseal have been deprecated in favor of gss_wrap/gss_unwrap with GSS-API v2 from January 1997 [1]. The first version of "The Kerberos Version 5 GSS-API Mechanism" [2] from June 1996 already says "GSS_Wrap() (formerly GSS_Seal())" and "GSS_Unwrap() (formerly GSS_Unseal())". Use the nondeprecated functions to avoid deprecation warnings. [1] https://tools.ietf.org/html/rfc2078 [2] https://tools.ietf.org/html/rfc1964 Closes https://github.com/curl/curl/pull/2356
2018-03-04NO_PROXY: fix for IPv6 numericals in the URLDaniel Stenberg

2018-03-03curl_ctype: fix macro redefinition warningsMarcel Raad
On MinGW and Cygwin, GCC and clang have been complaining about macro redefinitions since 4272a0b0fc49a1ac0ceab5c4a365c9f6ab8bf8e2. Fix this by undefining the macros before redefining them as suggested in https://github.com/curl/curl/pull/2269. Suggested-by: Daniel Stenberg
2018-02-28unit1309: fix warning on Windows x64Marcel Raad
When targeting x64, MinGW-w64 complains about conversions between 32-bit long and 64-bit pointers. Fix this by reusing the GNUTLS_POINTER_TO_SOCKET_CAST / GNUTLS_SOCKET_TO_POINTER_CAST logic from gtls.c, moving it to warnless.h as CURLX_POINTER_TO_INTEGER_CAST / CURLX_INTEGER_TO_POINTER_CAST. Closes https://github.com/curl/curl/pull/2341
2018-02-23spelling fixesViktor Szakats
Detected using the `codespell` tool. Also contains one URL protocol upgrade. Closes https://github.com/curl/curl/pull/2334
2018-02-21url: Add option CURLOPT_RESOLVER_START_FUNCTIONFrancisco Sedano
- Add new option CURLOPT_RESOLVER_START_FUNCTION to set a callback that will be called every time before a new resolve request is started (ie before a host is resolved) with a pointer to backend-specific resolver data. Currently this is only useful for ares. - Add new option CURLOPT_RESOLVER_START_DATA to set a user pointer to pass to the resolver start callback. Closes https://github.com/curl/curl/pull/2311
2018-02-21lib: CURLOPT_HAPPY_EYEBALLS_TIMEOUT => CURLOPT_HAPPY_EYEBALLS_TIMEOUT_MSJay Satiro
- In keeping with the naming of our other connect timeout options rename CURLOPT_HAPPY_EYEBALLS_TIMEOUT to CURLOPT_HAPPY_EYEBALLS_TIMEOUT_MS. This change adds the _MS suffix since the option expects milliseconds. This is more intuitive for our users since other connect timeout options that expect milliseconds use _MS such as CURLOPT_TIMEOUT_MS, CURLOPT_CONNECTTIMEOUT_MS, CURLOPT_ACCEPTTIMEOUT_MS. The tool option already uses an -ms suffix, --happy-eyeballs-timeout-ms. Follow-up to 2427d94 which added the lib and tool option yesterday. Ref: https://github.com/curl/curl/pull/2260
2018-02-21sasl: prefer PLAIN mechanism over LOGINPatrick Monnerat
SASL PLAIN is a standard, LOGIN only a draft. The LOGIN draft says PLAIN should be used instead if available.
2018-02-20url: Add option CURLOPT_HAPPY_EYEBALLS_TIMEOUTAnders Bakken
- Add new option CURLOPT_HAPPY_EYEBALLS_TIMEOUT to set libcurl's happy eyeball timeout value. - Add new optval macro CURL_HET_DEFAULT to represent the default happy eyeballs timeout value (currently 200 ms). - Add new tool option --happy-eyeballs-timeout-ms to expose CURLOPT_HAPPY_EYEBALLS_TIMEOUT. The -ms suffix is used because the other -timeout options in the tool expect seconds not milliseconds. Closes https://github.com/curl/curl/pull/2260
2018-02-20hostip: fix 'potentially uninitialized variable' warningJay Satiro
Follow-up to 50d1b33. Caught by AppVeyor.
2018-02-20CURLOPT_RESOLVE: Add support for multiple IP addresses per entryAnders Bakken
This enables users to preresolve but still take advantage of happy eyeballs and trying multiple addresses if some are not connecting. Ref: https://github.com/curl/curl/pull/2260
2018-02-16header callback: don't chop headers into smaller piecesDaniel Stenberg
Reported-by: Guido Berhoerster Fixes #2314 Closes #2316
2018-02-16http: fix the max header length detection logicDaniel Stenberg
Previously, it would only check for max length if the existing alloc buffer was to small to fit it, which often would make the header still get used. Reported-by: Guido Berhoerster Bug: https://curl.haxx.se/mail/lib-2018-02/0056.html Closes #2315
2018-02-16ssh: add two missing state namesDaniel Stenberg
The list of state names (used in debug builds) was out of sync in relation to the list of states (used in all builds). I now added an assert to make sure the sizes of the two lists match, to aid in detecting this mistake better in the future. Regression since c92d2e14cf, shipped in 7.58.0. Reported-by: Somnath Kundu Fixes #2312 Closes #2313

2018-02-12smtp: fix processing of initial dot in dataPatrick Monnerat
RFC 5321 4.1.1.4 specifies the CRLF terminating the DATA command should be taken into account when chasing the <CRLF>.<CRLF> end marker. Thus a leading dot character in data is also subject to escaping. Tests 911 and test server are adapted to this situation. New tests 951 and 952 check proper handling of initial dot in data. Closes #2304
