* TLS: fix SRP detection by using the proper #ifdefsDaniel Stenberg2020-08-281-1/+2
| | | | | | | | | | | | | | | USE_TLS_SRP will be true if *any* selected TLS backend can use SRP HAVE_OPENSSL_SRP is defined when OpenSSL can use it HAVE_GNUTLS_SRP is defined when GnuTLS can use it Clarify in the curl_verison_info docs that CURL_VERSION_TLSAUTH_SRP is set if at least one of the supported backends offers SRP.

* CURLE_PROXY: new error codeDaniel Stenberg2020-08-244-1/+145
| | | | | | | | | | | | Failures clearly returned from a (SOCKS) proxy now causes this return code. Previously the situation was not very clear as what would be returned and when. In addition: when this error code is returned, an application can use CURLINFO_PROXY_ERROR to query libcurl for the detailed error, which then returns a value from the new 'CURLproxycode' enum.

* openssl: Don't ignore CA paths when using Windows CA storeJay Satiro2020-06-221-2/+3
| | | | | | | | | | | | | This commit changes the behavior of CURLSSLOPT_NATIVE_CA so that it does not override CURLOPT_CAINFO / CURLOPT_CAPATH, or the hardcoded default locations. Instead the CA store can now be used at the same time. The change is due to the impending release. The issue is still being discussed. The behavior of CURLSSLOPT_NATIVE_CA is subject to change and is now documented as experimental. Ref: bc052cc (parent commit) Ref: https://github.com/curl/curl/issues/5585

* CURLINFO_CONDITION_UNMET: return true for 304 http status codeKwon-Young Choi2020-04-052-3/+5
| | | | | | | | | | | In libcurl, CURLINFO_CONDITION_UNMET is used to avoid writing to the output file if the server did not transfered a file based on time condition. In the same manner, getting a 304 HTTP response back from the server, for example after passing a custom If-Match-* header, also fulfill this condition. Fixes #5181 Closes #5183

* schannel: add "best effort" revocation check optionJohannes Schindelin2020-03-183-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Implement new option CURLSSLOPT_REVOKE_BEST_EFFORT and --ssl-revoke-best-effort to allow a "best effort" revocation check. A best effort revocation check ignores errors that the revocation check was unable to take place. The reasoning is described in detail below and discussed further in the PR. --- When running e.g. with Fiddler, the schannel backend fails with an unhelpful error message: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate. Sadly, many enterprise users who are stuck behind MITM proxies suffer the very same problem. This has been discussed in plenty of issues: https://github.com/curl/curl/issues/3727, https://github.com/curl/curl/issues/264, for example. In the latter, a Microsoft Edge developer even made the case that the common behavior is to ignore issues when a certificate has no recorded distribution point for revocation lists, or when the server is offline. This is also known as "best effort" strategy and addresses the Fiddler issue. Unfortunately, this strategy was not chosen as the default for schannel (and is therefore a backend-specific behavior: OpenSSL seems to happily ignore the offline servers and missing distribution points). To maintain backward-compatibility, we therefore add a new flag (`CURLSSLOPT_REVOKE_BEST_EFFORT`) and a new option (`--ssl-revoke-best-effort`) to select the new behavior. Due to the many related issues Git for Windows and GitHub Desktop, the plan is to make this behavior the default in these software packages. The test 2070 was added to verify this behavior, adapted from 310.

Prior to this change the user was directed to call free(), but that would not work in cases where the library and application use separate C runtimes and therefore have separate heap memory management.
