2016-11-24x509asn1: Restore the parameter check in Curl_getASN1ElementJay Satiro
- Restore the removed parts of the parameter check. Follow-up to 945f60e which altered the parameter check.
2016-11-25add CURLINFO_SCHEME, CURLINFO_PROTOCOL, and %{scheme}Frank Gevaerts
Adds access to the effectively used protocol/scheme to both libcurl and curl, both in string and numeric (CURLPROTO_*) form. Note that the string form will be uppercase, as it is just the internal string. As these strings are declared internally as const, and all other strings returned by curl_easy_getinfo() are de-facto const as well, string handling in getinfo.c got const-ified. Closes #1137

2016-11-24proxy: Support HTTPS proxy and SOCKS+HTTP(s)Alex Rousskov
* HTTPS proxies: An HTTPS proxy receives all transactions over an SSL/TLS connection. Once a secure connection with the proxy is established, the user agent uses the proxy as usual, including sending CONNECT requests to instruct the proxy to establish a [usually secure] TCP tunnel with an origin server. HTTPS proxies protect nearly all aspects of user-proxy communications as opposed to HTTP proxies that receive all requests (including CONNECT requests) in vulnerable clear text. With HTTPS proxies, it is possible to have two concurrent _nested_ SSL/TLS sessions: the "outer" one between the user agent and the proxy and the "inner" one between the user agent and the origin server (through the proxy). This change adds supports for such nested sessions as well. A secure connection with a proxy requires its own set of the usual SSL options (their actual descriptions differ and need polishing, see TODO): --proxy-cacert FILE CA certificate to verify peer against --proxy-capath DIR CA directory to verify peer against --proxy-cert CERT[:PASSWD] Client certificate file and password --proxy-cert-type TYPE Certificate file type (DER/PEM/ENG) --proxy-ciphers LIST SSL ciphers to use --proxy-crlfile FILE Get a CRL list in PEM format from the file --proxy-insecure Allow connections to proxies with bad certs --proxy-key KEY Private key file name --proxy-key-type TYPE Private key file type (DER/PEM/ENG) --proxy-pass PASS Pass phrase for the private key --proxy-ssl-allow-beast Allow security flaw to improve interop --proxy-sslv2 Use SSLv2 --proxy-sslv3 Use SSLv3 --proxy-tlsv1 Use TLSv1 --proxy-tlsuser USER TLS username --proxy-tlspassword STRING TLS password --proxy-tlsauthtype STRING TLS authentication type (default SRP) All --proxy-foo options are independent from their --foo counterparts, except --proxy-crlfile which defaults to --crlfile and --proxy-capath which defaults to --capath. Curl now also supports %{proxy_ssl_verify_result} --write-out variable, similar to the existing %{ssl_verify_result} variable. Supported backends: OpenSSL, GnuTLS, and NSS. * A SOCKS proxy + HTTP/HTTPS proxy combination: If both --socks* and --proxy options are given, Curl first connects to the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. TODO: Update documentation for the new APIs and --proxy-* options. Look for "Added in 7.XXX" marks.

2016-11-18lib: fix compiler warnings after de4de4e3c7cMarcel Raad
Visual C++ now complains about implicitly casting time_t (64-bit) to long (32-bit). Fix this by changing some variables from long to time_t, or explicitly casting to long where the public interface would be affected. Closes #1131

2016-11-14Curl_rand: fixed and moved to rand.cDaniel Stenberg
Now Curl_rand() is made to fail if it cannot get the necessary random level. Changed the proto of Curl_rand() slightly to provide a number of ints at once. Moved out from vtls, since it isn't a TLS function and vtls provides Curl_ssl_random() for this to use. Discussion: https://curl.haxx.se/mail/lib-2016-11/0119.html

2016-11-11URL-parser: for file://[host]/ URLs, the [host] must be localhostDaniel Stenberg
Previously, the [host] part was just ignored which made libcurl accept strange URLs misleading users. like "file://etc/passwd" which might've looked like it refers to "/etc/passwd" but is just "/passwd" since the "etc" is an ignored host name. Reported-by: Mike Crowe Assisted-by: Kamil Dudka

2016-11-09vtls: Fail on unrecognized param for CURLOPT_SSLVERSIONJay Satiro
- Fix GnuTLS code for CURL_SSLVERSION_TLSv1_2 that broke when the TLS 1.3 support was added in 6ad3add. - Homogenize across code for all backends the error message when TLS 1.3 is not available to "<backend>: TLS 1.3 is not yet supported". - Return an error when a user-specified ssl version is unrecognized. --- Prior to this change our code for some of the backends used the 'default' label in the switch statement (ie ver unrecognized) for ssl.version and treated it the same as CURL_SSLVERSION_DEFAULT.

2016-11-07http2: Don't send header fields prohibited by HTTP/2 specTatsuhiro Tsujikawa
Previously, we just ignored "Connection" header field. But HTTP/2 specification actually prohibits few more header fields.
