2017-08-28vtls: refactor out essential information about the SSL backendsJohannes Schindelin
There is information about the compiled-in SSL backends that is really no concern of any code other than the SSL backend itself, such as which function (if any) implements SHA-256 summing. And there is information that is really interesting to the user, such as the name, or the curl_sslbackend value. Let's factor out the latter into a publicly visible struct. This information will be used in the upcoming API to set the SSL backend globally. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: allow selecting which SSL backend to use at runtimeJohannes Schindelin
When building software for the masses, it is sometimes not possible to decide for all users which SSL backend is appropriate. Git for Windows, for example, uses cURL to perform clones, fetches and pushes via HTTPS, and some users strongly prefer OpenSSL, while other users really need to use Secure Channel because it offers enterprise-ready tools to manage credentials via Windows' Credential Store. The current Git for Windows versions use the ugly work-around of building libcurl once with OpenSSL support and once with Secure Channel support, and switching out the binaries in the installer depending on the user's choice. Needless to say, this is a super ugly workaround that actually only works in some cases: Git for Windows also comes in a portable form, and in a form intended for third-party applications requiring Git functionality, in which cases this "swap out libcurl-4.dll" simply is not an option. Therefore, the Git for Windows project has a vested interest in teaching cURL to make the SSL backend a *runtime* option. This patch makes that possible. By running ./configure with multiple --with-<backend> options, cURL will be built with multiple backends. For the moment, the backend can be configured using the environment variable CURL_SSL_BACKEND (valid values are e.g. "openssl" and "schannel").

2017-08-28vtls: encapsulate SSL backend-specific dataJohannes Schindelin
So far, all of the SSL backends' private data has been declared as part of the ssl_connect_data struct, in one big #if .. #elif .. #endif block. This can only work as long as the SSL backend is a compile-time option, something we want to change in the next commits. Therefore, let's encapsulate the exact data needed by each SSL backend into a private struct, and let's avoid bleeding any SSL backend-specific information into urldata.h. This is also necessary to allow multiple SSL backends to be compiled in at the same time, as e.g. OpenSSL's and CyaSSL's headers cannot be included in the same .c file. To avoid too many malloc() calls, we simply append the private structs to the connectdata struct in allocate_conn(). This requires us to take extra care of alignment issues: struct fields often need to be aligned on certain boundaries e.g. 32-bit values need to be stored at addresses that divide evenly by 4 (= 32 bit / 8 bit-per-byte). We do that by assuming that no SSL backend's private data contains any fields that need to be aligned on boundaries larger than `long long` (typically 64-bit) would need. Under this assumption, we simply add a dummy field of type `long long` to the `struct connectdata` struct. This field will never be accessed but acts as a placeholder for the four instances of ssl_backend_data instead. the size of each ssl_backend_data struct is stored in the SSL backend-specific metadata, to allow allocate_conn() to know how much extra space to allocate, and how to initialize the ssl[sockindex]->backend and proxy_ssl[sockindex]->backend pointers. This would appear to be a little complicated at first, but is really necessary to encapsulate the private data of each SSL backend correctly. And we need to encapsulate thusly if we ever want to allow selecting CyaSSL and OpenSSL at runtime, as their headers cannot be included within the same .c file (there are just too many conflicting definitions and declarations for that).

2017-08-28vtls: prepare the SSL backends for encapsulated private dataJohannes Schindelin
At the moment, cURL's SSL backend needs to be configured at build time. As such, it is totally okay for them to hard-code their backend-specific data in the ssl_connect_data struct. In preparation for making the SSL backend a runtime option, let's make the access of said private data a bit more abstract so that it can be adjusted later in an easy manner. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28getinfo: access SSL internals via Curl_sslJohannes Schindelin
In the ongoing endeavor to abstract out all SSL backend-specific functionality, this is the next step: Instead of hard-coding how the different SSL backends access their internal data in getinfo.c, let's implement backend-specific functions to do that task. This will also allow for switching SSL backends as a runtime option. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: remove obsolete declarations of SSL backend functionalityJohannes Schindelin
These functions are all available via the Curl_ssl struct now, no need to declare them separately anymore. As the global declarations are removed, the corresponding function definitions are marked as file-local. The only two exceptions here are Curl_mbedtls_shutdown() and Curl_polarssl_shutdown(): only the declarations were removed, there are no function definitions to mark file-local. Please note that Curl_nss_force_init() is *still* declared globally, as the only SSL backend-specific function, because it was introduced specifically for the use case where cURL was compiled with `--without-ssl --with-nss`. For details, see f3b77e561 (http_ntlm: add support for NSS, 2010-06-27). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

2017-08-28vtls: convert the have_curlssl_* constants to runtime flagsJohannes Schindelin
The entire idea of introducing the Curl_ssl struct to describe SSL backends is to prepare for choosing the SSL backend at runtime. To that end, convert all the #ifdef have_curlssl_* style conditionals to use bit flags instead. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: move sha256sum into the Curl_ssl structJohannes Schindelin
The SHA-256 checksumming is also an SSL backend-specific function. Let's include it in the struct declaring the functionality of SSL backends. In contrast to MD5, there is no fall-back code. To indicate this, the respective entries are NULL for those backends that offer no support for SHA-256 checksumming. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: move md5sum into the Curl_ssl structJohannes Schindelin
The MD5 summing is also an SSL backend-specific function. So let's include it, offering the previous fall-back code as a separate function now: Curl_none_md5sum(). To allow for that, the signature had to be changed so that an error could be returned from the implementation (Curl_none_md5sum() can run out of memory).

2017-08-28vtls: use the Curl_ssl struct to access all SSL backends' functionalityJohannes Schindelin
This is the first step to unify the SSL backend handling. Now all the SSL backend-specific functionality is accessed via a global instance of the Curl_ssl struct. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2017-08-28vtls: declare Curl_ssl structs for every SSL backendJohannes Schindelin

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.
