2016-05-11openssl: stricter connection check functionJay Satiro
- In the case of recv error, limit returning 'connection still in place' to EINPROGRESS, EAGAIN and EWOULDBLOCK. This is an improvement on the parent commit which changed the openssl connection check to use recv MSG_PEEK instead of SSL_peek. Ref: https://github.com/curl/curl/commit/856baf5#comments
2016-05-11TLS: SSL_peek is not a const operationAnders Bakken
Calling SSL_peek can cause bytes to be read from the raw socket which in turn can upset the select machinery that determines whether there's data available on the socket. Since Curl_ossl_check_cxn only tries to determine whether the socket is alive and doesn't actually need to see the bytes SSL_peek seems like the wrong function to call. We're able to occasionally reproduce a connect timeout due to this bug. What happens is that Curl doesn't know to call SSL_connect again after the peek happens since data is buffered in the SSL buffer and thus select won't fire for this socket. Closes #795
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
2016-05-01tls: make setting pinnedkey option fail if not supportedDaniel Stenberg
to make it obvious to users trying to use the feature with TLS backends not supporting it. Discussed in #781 Reported-by: Travis Burtrum
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. Bug: https://curl.haxx.se/mail/lib-2016-01/0070.html Reported-by: Thomas Glanzmann Bug: https://curl.haxx.se/mail/lib-2016-04/0095.html Reported-by: Moti Avrahami
2016-04-26openssl: avoid BN_print a NULL bignumDaniel Stenberg
OpenSSL 1.1.0-pre seems to return NULL(?) for a whole lot of those numbers so make sure the function handles this. Reported-by: Linus Nordberg

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.

Add ALPN support for schannel. This allows cURL to negotiate HTTP/2.0 connections when built with schannel. Closes #724

2016-03-17openssl: adapt to API breakage in ERR_remove_thread_state()Gisle Vanem
The OpenSSL API change that broke this is "Convert ERR_STATE to new multi-threading API": openssl commit 8509dcc. Closes #713
2016-03-17openssl: verbose: show matching SAN patternDaniel Stenberg
... to allow users to see which specfic wildcard that matched when such is used. Also minor logic cleanup to simplify the code, and I removed all tabs from verbose strings.

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.

2016-02-16openssl: avoid direct PKEY access with OpenSSL 1.1.0Viktor Szakats

2016-02-10nss: search slash in forward direction in dup_nickname()Kamil Dudka
It is wasteful to search it backwards if we look for _any_ slash.
2016-02-10nss: do not count enabled cipher-suitesKamil Dudka
We only care if at least one cipher-suite is enabled, so it does not make any sense to iterate till the end and count all enabled cipher-suites.

Closes #626
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
2016-02-09openssl: remove most BoringSSL #ifdefs.David Benjamin
As of https://boringssl-review.googlesource.com/#/c/6980/, almost all of BoringSSL #ifdefs in cURL should be unnecessary: - BoringSSL provides no-op stubs for compatibility which replaces most #ifdefs. - DES_set_odd_parity has been in BoringSSL for nearly a year now. Remove the compatibility codepath. - With a small tweak to an extend_key_56_to_64 call, the NTLM code builds fine. - Switch OCSP-related #ifdefs to the more generally useful OPENSSL_NO_OCSP. The only #ifdefs which remain are Curl_ossl_version and the #undefs to work around OpenSSL and wincrypt.h name conflicts. (BoringSSL leaves that to the consumer. The in-header workaround makes things sensitive to include order.) This change errs on the side of removing conditionals despite many of the restored codepaths being no-ops. (BoringSSL generally adds no-op compatibility stubs when possible. OPENSSL_VERSION_NUMBER #ifdefs are bad enough!) Closes #640
2016-02-08configure: --with-ca-fallback: use built-in TLS CA fallbackLudwig Nussel
When trying to verify a peer without having any root CA certificates set, this makes libcurl use the TLS library's built in default as fallback. Closes #569
2016-02-06openssl: Fix signed/unsigned mismatch warning in X509V3_extJay Satiro
sk_X509_EXTENSION_num may return an unsigned integer, however the value will fit in an int. Bug: https://github.com/curl/curl/commit/dd1b44c#commitcomment-15913896 Reported-by: Gisle Vanem

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.

2016-01-14openssl: improved error detection/reportingDaniel Stenberg
... by extracting the LIB + REASON from the OpenSSL error code. OpenSSL 1.1.0+ returned a new func number of another cerfificate fail so this required a fix and this is the better way to catch this error anyway.
2016-01-14openssl: for 1.1.0+ they now provide a SSLeay() macro of their ownDaniel Stenberg

2016-01-07mbedtls: Fix ALPN supportJay Satiro
- Fix ALPN reply detection. - Wrap nghttp2 code in ifdef USE_NGHTTP2. Prior to this change ALPN and HTTP/2 did not work properly in mbedTLS.
