2020-05-08CURLOPT_SSL_OPTIONS: add *_NATIVE_CA to use Windows CA store (with openssl)Gilles Vollant
Closes #4346
2020-03-30cleanup: insert newline after if() conditionsDaniel Stenberg
Our code style mandates we put the conditional block on a separate line. These mistakes are now detected by the updated checksrc.
2020-03-26openssl: adapt to functions marked as deprecated since version 3Daniel Stenberg
OpenSSL 3 deprecates SSL_CTX_load_verify_locations and the MD4, DES functions we use. Fix the MD4 and SSL_CTX_load_verify_locations warnings. In configure, detect OpenSSL v3 and if so, inhibit the deprecation warnings. OpenSSL v3 deprecates the DES functions we use for NTLM and until we rewrite the code to use non-deprecated functions we better ignore these warnings as they don't help us. Closes #5139
2020-03-19openssl: remove the BACKEND define kludgeDaniel Stenberg
Use a proper variable instead to make it easier to use a debugger and read the code.
2020-02-03openssl: remove redundant assignmentMarcel Raad
Fixes a scan-build failure on Bionic. Closes https://github.com/curl/curl/pull/4872
2020-01-23openssl: make CURLINFO_CERTINFO not truncate x509v3 fieldsDaniel Stenberg
Avoid "reparsing" the content and instead deliver more exactly what is provided in the certificate and avoid truncating the data after 512 bytes as done previously. This no longer removes embedded newlines. Fixes #4837 Reported-by: bnfp on github Closes #4841
2019-12-03openssl: CURLSSLOPT_NO_PARTIALCHAIN can disable partial cert chainsDaniel Stenberg
Closes #4655
2019-12-03openssl: set X509_V_FLAG_PARTIAL_CHAINDaniel Stenberg
Have intermediate certificates in the trust store be treated as trust-anchors, in the same way as self-signed root CA certificates are. This allows users to verify servers using the intermediate cert only, instead of needing the whole chain. Other TLS backends already accept partial chains.

2019-12-01build: Disable Visual Studio warning "conditional expression is constant"Jay Satiro
- Disable warning C4127 "conditional expression is constant" globally in curl_setup.h for when building with Microsoft's compiler. This mainly affects building with the Visual Studio project files found in the projects dir. Prior to this change the cmake and winbuild build systems already disabled 4127 globally for when building with Microsoft's compiler. Also, 4127 was already disabled for all build systems in the limited circumstance of the WHILE_FALSE macro which disabled the warning specifically for while(0). This commit removes the WHILE_FALSE macro and all other cruft in favor of disabling globally in curl_setup. Background: We have various macros that cause 0 or 1 to be evaluated, which would cause warning C4127 in Visual Studio. For example this causes it: #define Curl_resolver_asynch() 1 Full behavior is not clearly defined and inconsistent across versions. However it is documented that since VS 2015 Update 3 Microsoft has addressed this somewhat but not entirely, not warning on while(true) for example. Prior to this change some C4127 warnings occurred when I built with Visual Studio using the generated projects in the projects dir. Closes https://github.com/curl/curl/pull/4658
2019-12-01openssl: retrieve reported LibreSSL version at runtimeJay Satiro
- Retrieve LibreSSL runtime version when supported (>= 2.7.1). For earlier versions we continue to use the compile-time version. Ref: https://man.openbsd.org/OPENSSL_VERSION_NUMBER.3 Closes https://github.com/curl/curl/pull/2425
2019-11-22openssl: Revert to less sensitivity for SYSCALL errorsJay Satiro
- Disable the extra sensitivity except in debug builds (--enable-debug). - Improve SYSCALL error message logic in ossl_send and ossl_recv so that "No error" / "Success" socket error text isn't shown on SYSCALL error. Prior to this change 0ab38f5 (precedes 7.67.0) increased the sensitivity of OpenSSL's SSL_ERROR_SYSCALL error so that abrupt server closures were also considered errors. For example, a server that does not send a known protocol termination point (eg HTTP content length or chunked encoding) _and_ does not send a TLS termination point (close_notify alert) would cause an error if it closed the connection. To be clear that behavior made it into release build 7.67.0 unintentionally. Several users have reported it as an issue. Ultimately the idea is a good one, since it can help prevent against a truncation attack. Other SSL backends may already behave similarly (such as Windows native OS SSL Schannel). However much more of our user base is using OpenSSL and there is a mass of legacy users in that space, so I think that behavior should be partially reverted and then rolled out slowly. This commit changes the behavior so that the increased sensitivity is disabled in all curl builds except curl debug builds (DEBUGBUILD). If after a period of time there are no major issues then it can be enabled in dev and release builds with the newest OpenSSL (1.1.1+), since users using the newest OpenSSL are the least likely to have legacy problems.

2019-09-26openssl: use strerror on SSL_ERROR_SYSCALLDaniel Stenberg
Instead of showing the somewhat nonsensical errno number, use strerror() to provide a more relatable error message. Closes #4411
2019-09-23vtls: fix narrowing conversion warningsMarcel Raad
Curl_timeleft returns `timediff_t`, which is 64 bits wide also on 32-bit systems since commit b1616dad8f0. Closes https://github.com/curl/curl/pull/4398
2019-09-22openssl: fix compiler warning with LibreSSLMarcel Raad
It was already fixed for BoringSSL in commit a0f8fccb1e0. LibreSSL has had the second argument to SSL_CTX_set_min_proto_version as uint16_t ever since the function was added in [0].

2019-07-19source: remove names from source commentsDaniel Stenberg
Several reasons: - we can't add everyone who's helping out so its unfair to just a few selected ones. - we already list all helpers in THANKS and in RELEASE-NOTES for each release - we don't want to give the impression that some parts of the code is "owned" or "controlled" by specific persons Assisted-by: Daniel Gustafsson Closes #4129

2019-06-26openssl: disable engine if OPENSSL_NO_UI_CONSOLE is definedDaniel Stenberg
... since that needs UI_OpenSSL() which isn't provided when OpenSSL is built with OPENSSL_NO_UI_CONSOLE which happens when OpenSSL is built for UWP (with "VC-WIN32-UWP"). Reported-by: Vasily Lobaskin Fixes #4073 Closes #4077
2019-06-18openssl: fix pubkey/signature algorithm detection in certinfoGergely Nagy
Certinfo gives the same result for all OpenSSL versions. Also made printing RSA pubkeys consistent with older versions. Reported-by: Michael Wallner Fixes #3706 Closes #4030
2019-06-17openssl: remove outdated commentDaniel Gustafsson
OpenSSL used to call exit(1) on syntax errors in OPENSSL_config(), which is why we switched to CONF_modules_load_file() and introduced a comment stating why. This behavior was however changed in OpenSSL commit abdd677125f3a9e3082f8c5692203590fdb9b860, so remove the now outdated and incorrect comment. The mentioned commit also declares OPENSSL_config() deprecated so keep the current coding. Closes #4033 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

They serve very little purpose and mostly just add noise. Most of them have been around for a very long time. I read them all before removing or rephrasing them. Ref: #3876 Closes #3883
2019-05-08OpenSSL: Report -fips in version if OpenSSL is built with FIPSRicky Leverence
Older versions of OpenSSL report FIPS availabilty via an OPENSSL_FIPS define. It uses this define to determine whether to publish -fips at the end of the version displayed. Applications that utilize the version reported by OpenSSL will see a mismatch if they compare it to what curl reports, as curl is not modifying the version in the same way. This change simply adds a check to see if OPENSSL_FIPS is defined, and will alter the reported version to match what OpenSSL itself provides. This only appears to be applicable in versions of OpenSSL <1.1.1 Closes #3771
2019-05-01multi: provide Curl_multiuse_state to update informationDaniel Stenberg
As soon as a TLS backend gets ALPN conformation about the specific HTTP version it can now set the multiplex situation for the "bundle" and trigger moving potentially queued up transfers to the CONNECT state.
2019-04-12openssl: mark connection for close on TLS close_notifyDaniel Stenberg

2019-03-15configure: add --with-amisslChris Young
AmiSSL is an Amiga native library which provides a wrapper over OpenSSL. It also requires all programs using it to use bsdsocket.library directly, rather than accessing socket functions through clib, which libcurl was not necessarily doing previously.

2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
The function does not return the same value as snprintf() normally does, so readers may be mislead into thinking the code works differently than it actually does. A different function name makes this easier to detect. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297
2018-11-21openssl: support session resume with TLS 1.3Michael Kaufmann
Session resumption information is not available immediately after a TLS 1.3 handshake. The client must wait until the server has sent a session ticket. Use OpenSSL's "new session" callback to get the session information and put it into curl's session cache. For TLS 1.3 sessions, this callback will be invoked after the server has sent a session ticket. The "new session" callback is invoked only if OpenSSL's session cache is enabled, so enable it and use the "external storage" mode which lets curl manage the contents of the session cache. A pointer to the connection data and the sockindex are now saved as "SSL extra data" to make them available to the callback. This approach also works for old SSL/TLS versions and old OpenSSL versions. Reviewed-by: Daniel Stenberg <daniel@haxx.se> Fixes #3202 Closes #3271

2018-11-16openssl: do not log excess "TLS app data" lines for TLS 1.3Peter Wu
The SSL_CTX_set_msg_callback callback is not just called for the Handshake or Alert protocols, but also for the raw record header (SSL3_RT_HEADER) and the decrypted inner record type (SSL3_RT_INNER_CONTENT_TYPE). Be sure to ignore the latter to avoid excess debug spam when using `curl -v` against a TLSv1.3-enabled server: * TLSv1.3 (IN), TLS app data, [no content] (0): (Following this message, another callback for the decrypted handshake/alert messages will be be present anyway.) Closes https://github.com/curl/curl/pull/3281
2018-11-09openssl: support BoringSSL TLS renegotiationJérémy Rocher
As per BoringSSL porting documentation [1], BoringSSL rejects peer renegotiations by default. curl fails when trying to authenticate to server through client certificate if it is requested by server after the initial TLS handshake. Enable renegotiation by default with BoringSSL to get same behavior as with OpenSSL. This is done by calling SSL_set_renegotiate_mode [2] which was introduced in commit 1d5ef3bb1eb9 [3]. 1 - https://boringssl.googlesource.com/boringssl/+/HEAD/PORTING.md#tls-renegotiation 2 - https://boringssl.googlesource.com/boringssl/+/master/include/openssl/ssl.h#3482 3 - https://boringssl.googlesource.com/boringssl/+/1d5ef3bb1eb97848617db5e7d633d735a401df86 Signed-off-by: Jérémy Rocher <rocher.jeremy@gmail.com> Fixes #3258 Closes #3259
