2014-08-07openssl: replace call to OPENSSL_configDaniel Stenberg
OPENSSL_config() is "strongly recommended" to use but unfortunately that function makes an exit() call on wrongly formatted config files which makes it hard to use in some situations. OPENSSL_config() itself calls CONF_modules_load_file() and we use that instead and we ignore its return code! Reported-by: Jan Ehrhardt Bug: http://curl.haxx.se/bug/view.cgi?id=1401
2014-08-05Curl_ossl_version: adapted to detect BoringSSLDaniel Stenberg
This seems to be the way it should work. Right now we can't build with BoringSSL and try this out properly due to a minor API breakage.
2014-08-04Curl_ossl_version: detect and show libresslDaniel Stenberg
LibreSSL is otherwise OpenSSL API compliant (so far)
2014-08-01openssl: make ossl_send return CURLE_OK betterDaniel Stenberg
Previously it only returned a CURLcode for errors, which is when it returns a different size than what was passed in to it. The http2 code only checked the curlcode and thus failed.
2014-07-30vtls: make the random function mandatory in the TLS backendDaniel Stenberg
To force each backend implementation to really attempt to provide proper random. If a proper random function is missing, then we can explicitly make use of the default one we use when TLS support is missing. This commit makes sure it works for darwinssl, gnutls, nss and openssl.
2014-06-03Curl_ossl_init: call OPENSSL_config for initing enginesDaniel Stenberg
Bug: http://curl.haxx.se/mail/lib-2014-06/0003.html Reported-by: Дмитрий Фалько
2014-05-23openssl: Fix uninitialized variable use in NPN callbackTatsuhiro Tsujikawa
OpenSSL passes out and outlen variable uninitialized to select_next_proto_cb callback function. If the callback function returns SSL_TLSEXT_ERR_OK, the caller assumes the callback filled values in out and outlen and processes as such. Previously, if there is no overlap in protocol lists, curl code does not fill any values in these variables and returns SSL_TLSEXT_ERR_OK, which means we are triggering undefined behavior. valgrind warns this. This patch fixes this issue by fallback to HTTP/1.1 if there is no overlap.
2014-05-15CURLINFO_SSL_VERIFYRESULT: assign at first connect callDaniel Stenberg
The variable wasn't assigned at all until step3 which would lead to a failed connect never assigning the variable and thus returning a bad value. Reported-by: Larry Lin Bug: http://curl.haxx.se/mail/lib-2014-04/0203.html
2014-05-12openssl: unbreak PKCS12 supportDaniel Stenberg
Regression introduced in ce362e8eb9c (7.31.0) Bug: http://curl.haxx.se/bug/view.cgi?id=1371 Reported-by: Dmitry
2014-05-04openssl: biomem->data is not zero terminatedDaniel Stenberg
So printf(%s) on it or reading before bounds checking is wrong, fixing it. Could previously lead to reading out of boundary. Reported-by: Török Edwin
2014-04-03http2+openssl: fix compiler warnings in ALPN using codeDaniel Stenberg
2014-03-31http2: let openssl mention the exact protocol negotiatedDaniel Stenberg
Remove a superfluous "negotiated http2" info line
2014-03-31http2: remove _DRAFT09 from the NPN_HTTP2 enumDaniel Stenberg
We're progressing throught drafts so there's no point in having a fixed one in a symbol that'll survive.

2014-02-11openssl: honor --[no-]alpn|npn command line switchFabian Frank
Disable ALPN or NPN if requested by the user.
2014-02-04gtls: add ALPN supportFabian Frank
Add ALPN support when using GnuTLS >= 3.2.0. This allows libcurl to negotiate HTTP/2.0 for https connections when built with GnuTLS. See: http://www.gnutls.org/manual/gnutls.html#Application-Layer-Protocol-Negotiation-_0028ALPN_0029 http://tools.ietf.org/html/draft-ietf-tls-applayerprotoneg-04
2014-02-03openssl: add ALPN supportFabian Frank
Add ALPN support when using OpenSSL. This will offer ALPN and NPN to the server, who can respond with either one or none of the two. OpenSSL >= 1.0.2 is required, which means as of today obtaining a snapshot from ftp://ftp.openssl.org/snapshot/. See: http://tools.ietf.org/html/draft-ietf-tls-applayerprotoneg-04 https://github.com/openssl/openssl/blob/ba168244a14bbd056e502d7daa04cae4aabe9d0d/ssl/ssl_lib.c#L1787
2014-01-30http2-openssl: verify that NPN functionality is presentDaniel Stenberg
2014-01-30openssl: set up hooks with to perform NPNFabian Frank
NPN is what is available in the wild today to negotiate SPDY or HTTP/2.0 connections. It is expected to be replaced by ALPN in the future. If HTTP/2.0 is negotiated, this is indicated for the entire connection and http.c is expected to initialize itself for HTTP/2.0 instead of HTTP/1.1. see: http://technotes.googlecode.com/git/nextprotoneg.html http://tools.ietf.org/html/draft-ietf-tls-applayerprotoneg-04
2014-01-12OpenSSL: deselect weak ciphers by defaultDaniel Stenberg
By default even recent versions of OpenSSL support and accept both "export strength" ciphers, small-bitsize ciphers as well as downright deprecated ones. This change sets a default cipher set that avoids the worst ciphers, and subsequently makes https://www.howsmyssl.com/a/check no longer grade curl/OpenSSL connects as 'Bad'.

2014-01-03openssl: allow explicit sslv2 selectionDaniel Stenberg
If OpenSSL is built to support SSLv2 this brings back the ability to explicitly select that as a protocol level. Reported-by: Steve Holme Bug: http://curl.haxx.se/mail/lib-2014-01/0013.html

2014-01-02OpenSSL: Fix forcing SSLv3 connectionsBarry Abrahamson
Some feedback provided by byte_bucket on IRC pointed out that commit db11750cfa5b1 wasn’t really correct because it allows for “upgrading” to a newer protocol when it should be only allowing for SSLv3. This change fixes that. When SSLv3 connection is forced, don't allow SSL negotiations for newer versions. Feedback provided by byte_bucket in #curl. This behavior is also consistent with the other force flags like --tlsv1.1 which doesn't allow for TLSv1.2 negotiation, etc Feedback-by: byte_bucket Bug: http://curl.haxx.se/bug/view.cgi?id=1319
2014-01-01OpenSSL: Fix forcing SSLv3 connectionsBarry Abrahamson
Since ad34a2d5c87c7f4b14e8dded3 (present in 7.34.0 release) forcing SSLv3 will always return the error "curl: (35) Unsupported SSL protocol version" Can be replicated with `curl -I -3 https://www.google.com/`. This fix simply allows for v3 to be forced.
