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.
2016-11-09vtls: 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.

2016-10-18select: switch to macros in uppercaseDaniel Stenberg
Curl_select_ready() was the former API that was replaced with Curl_select_check() a while back and the former arg setup was provided with a define (in order to leave existing code unmodified). Now we instead offer SOCKET_READABLE and SOCKET_WRITABLE for the most common shortcuts where only one socket is checked. They're also more visibly macros.
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.
2016-08-01mbedtls: 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
2016-06-22internals: 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.
2016-06-01vtls: 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

2016-05-24mbedtls: fix includes so snprintf() worksDaniel Stenberg
Regression from the previous *printf() rearrangements, this file missed to include the correct header to make sure snprintf() works universally. Reported-by: Moti Avrahami Bug: https://curl.haxx.se/mail/lib-2016-05/0196.html
2016-05-17mbedtls/polarssl: set "hostname" unconditionallyDaniel Stenberg
...as otherwise the TLS libs will skip the CN/SAN check and just allow connection to any server. curl previously skipped this function when SNI wasn't used or when connecting to an IP address specified host. CVE-2016-3739 Bug: https://curl.haxx.se/docs/adv_20160518A.html Reported-by: Moti Avrahami
2016-05-09TLS: move the ALPN/NPN enable bits to the connectionDaniel Stenberg
Only protocols that actually have a protocol registered for ALPN and NPN should try to get that negotiated in the TLS handshake. That is only HTTPS (well, http/1.1 and http/2) right now. Previously ALPN and NPN would wrongly be used in all handshakes if libcurl was built with it enabled. Reported-by: Jay Satiro Fixes #789
2016-04-28mbedtls: Fix session resumeJay Satiro
This also fixes PolarSSL session resume. Prior to this change the TLS session information wasn't properly saved and restored for PolarSSL and mbedTLS.

2016-04-07mbedtls.c: changed private prefix to mbed_Daniel Stenberg
mbedtls_ is the prefix used by the mbedTLS library itself so we should avoid using that for our private functions.

2016-03-05mbedtls: fix user-specified SSL protocol versionJay Satiro
Prior to this change when a single protocol CURL_SSLVERSION_ was specified by the user that version was set only as the minimum version but not as the maximum version as well.

2016-02-09mbedtls: fix ALPN usage segfaultDaniel Stenberg
Since we didn't keep the input argument around after having called mbedtls, it could end up accessing the wrong memory when figuring out the ALPN protocols. Closes #642

2016-01-18mbedtls: Fix pinned key return value on failJay Satiro
- Switch from verifying a pinned public key in a callback during the certificate verification to inline after the certificate verification. The callback method had three problems: 1. If a pinned public key didn't match, CURLE_SSL_PINNEDPUBKEYNOTMATCH was not returned. 2. If peer certificate verification was disabled the pinned key verification did not take place as it should. 3. (related to #2) If there was no certificate of depth 0 the callback would not have checked the pinned public key. Though all those problems could have been fixed it would have made the code more complex. Instead we now verify inline after the certificate verification in mbedtls_connect_step2.
