2018-04-06FTP: allow PASV on IPv6 connections when a proxy is being usedLaurie Clark-Michalek
In the situation of a client connecting to an FTP server using an IPv6 tunnel proxy, the connection info will indicate that the connection is IPv6. However, because the server behing the proxy is IPv4, it is permissable to attempt PSV mode. In the case of the FTP server being IPv4 only, EPSV will always fail, and with the current logic curl will be unable to connect to the server, as the IPv6 fwdproxy causes curl to think that EPSV is impossible. Closes #2432
2018-04-06file: restore old behavior for file:////foo/bar URLsJon DeVree
curl 7.57.0 and up interpret this according to Appendix E.3.2 of RFC 8089 but then returns an error saying this is unimplemented. This is actually a regression in behavior on both Windows and Unix. Before curl 7.57.0 this URL was treated as a path of "//foo/bar" and then passed to the relevant OS API. This means that the behavior of this case is actually OS dependent. The Unix path resolution rules say that the OS must handle swallowing the extra "/" and so this path is the same as "/foo/bar" The Windows path resolution rules say that this is a UNC path and automatically handles the SMB access for the program. So curl on Windows was already doing Appendix E.3.2 without any special code in curl. Regression Closes #2438
2018-04-06Revert "openssl: Don't add verify locations when verifypeer==0"Gaurav Malhotra
This reverts commit dc85437736e1fc90e689bb1f6c51c8f1aa9430eb. libcurl (with the OpenSSL backend) performs server certificate verification even if verifypeer == 0 and the verification result is available using CURLINFO_SSL_VERIFYRESULT. The commit that is being reverted caused the CURLINFO_SSL_VERIFYRESULT to not have useful information for the verifypeer == 0 use case (it would always have X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY). Closes #2451
2018-04-06tls: fix mbedTLS 2.7.0 build + handle sha256 failuresWyatt O'Day

closes #2458
2018-04-04cookie: fix and optimize 2nd top level domain name extractionPatrick Monnerat
This fixes a segfault occurring when a name of the (invalid) form "domain..tld" is processed. test46 updated to cover this case. Follow-up to commit c990ead. Ref: https://github.com/curl/curl/pull/2440
2018-04-04openssl: provide defines for argument typecasts to build warning-freeDaniel Stenberg
... as OpenSSL >= 1.1.0 and libressl >= 2.7.0 use different argument types.
2018-04-04openssl: fix build with LibreSSL 2.7Bernard Spil

2018-04-02cookie: store cookies per top-level-domain-specific hash tableLauri Kasanen
This makes libcurl handle thousands of cookies much better and speedier. Closes #2440
2018-04-02cookies: when reading from a file, only remove_expired onceLauri Kasanen
This drops the cookie load time for 8k cookies from 178ms to 15ms. Closes #2441
2018-03-24threaded resolver: track resolver time and set suitable timeout valuesDaniel Stenberg
In order to make curl_multi_timeout() return suitable "sleep" times even when there's no socket to wait for while the name is being resolved in a helper thread. It will increases the timeouts as time passes. Closes #2419

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

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

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

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.

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

2018-03-03curl_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

2018-02-21url: 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
