2018-11-01schannel: use Curl_ prefix for global private symbolsDaniel Stenberg
Curl_verify_certificate() must use the Curl_ prefix since it is globally available in the lib and otherwise steps outside of our namespace! Closes #3201
2018-10-30vtls: add MesaLink to curl_sslbackend enumDaniel Gustafsson
MesaLink support was added in commit 57348eb97d1b8fc3742e02c but the backend was never added to the curl_sslbackend enum in curl/curl.h. This adds the new backend to the enum and updates the relevant docs. Closes #3195 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2018-10-27openssl: output the correct cipher list on TLS 1.3 errorDaniel Stenberg

2018-10-07gskit: make sure to terminate version stringDaniel Gustafsson
In case a very small buffer was passed to the version function, it could result in the buffer not being NULL-terminated since strncpy() doesn't guarantee a terminator on an overflowed buffer. Rather than adding code to terminate (and handle zero-sized buffers), move to using snprintf() instead like all the other vtls backends.

2018-10-03memory: ensure to check allocation resultsDaniel Gustafsson
The result of a memory allocation should always be checked, as we may run under memory pressure where even a small allocation can fail. This adds checking and error handling to a few cases where the allocation wasn't checked for success. In the ftp case, the freeing of the path variable is moved ahead of the allocation since there is little point in keeping it around across the strdup, and the separation makes for more readable code. In nwlib, the lock is aslo freed in the error path. Also bumps the copyright years on affected files.

2018-09-20vtls: fix ssl version "or later" behavior change for many backendsJay Satiro
- Treat CURL_SSLVERSION_MAX_NONE the same as CURL_SSLVERSION_MAX_DEFAULT. Prior to this change NONE would mean use the minimum version also as the maximum. This is a follow-up to 6015cef which changed the behavior of setting the SSL version so that the requested version would only be the minimum and not the maximum. It appears it was (mostly) implemented in OpenSSL but not other backends. In other words CURL_SSLVERSION_TLSv1_0 used to mean use just TLS v1.0 and now it means use TLS v1.0 *or later*. - Fix CURL_SSLVERSION_MAX_DEFAULT for OpenSSL. Prior to this change CURL_SSLVERSION_MAX_DEFAULT with OpenSSL was erroneously treated as always TLS 1.3, and would cause an error if OpenSSL was built without TLS 1.3 support.

2018-09-07configure: add option to disable automatic OpenSSL config loadingPhilipp Waehnert
Sometimes it may be considered a security risk to load an external OpenSSL configuration automatically inside curl_global_init(). The configuration option --disable-ssl-auto-load-config disables this automatism. The Windows build scripts winbuild/Makefile.vs provide a corresponding option ENABLE_SSL_AUTO_LOAD_CONFIG accepting a boolean value. Setting neither of these options corresponds to the previous behavior loading the external OpenSSL configuration automatically. Fixes #2724 Closes #2791

2018-08-24schannel: client certificate store opening fixIhor Karpenko
1) Using CERT_STORE_OPEN_EXISTING_FLAG ( or CERT_STORE_READONLY_FLAG ) while opening certificate store would be sufficient in this scenario and less-demanding in sense of required user credentials ( for example, IIS_IUSRS will get "Access Denied" 0x05 error for existing CertOpenStore call without any of flags mentioned above ), 2) as 'cert_store_name' is a DWORD, attempt to format its value like a string ( in "Failed to open cert store" error message ) will throw null pointer exception 3) adding GetLastError(), in my opinion, will make error message more useful.

2018-07-11openssl: assume engine support in 1.0.0 or laterPaul Howarth
Commit 38203f1585da changed engine detection to be version-based, with a baseline of openssl 1.0.1. This does in fact break builds with openssl 1.0.0, which has engine support - the configure script detects that ENGINE_cleanup() is available - but <openssl/engine.h> doesn't get included to declare it. According to upstream documentation, engine support was added to mainstream openssl builds as of version 0.9.7: https://github.com/openssl/openssl/blob/master/README.ENGINE This commit drops the version test down to 1.0.0 as version 1.0.0d is the oldest version I have to test with.

2018-06-12schannel: support selecting ciphersRobert Prag
Given the contstraints of SChannel, I'm exposing these as the algorithms themselves instead; while replicating the ciphersuite as specified by OpenSSL would have been preferable, I found no way in the SChannel API to do so. To use this from the commandline, you need to pass the names of contants defining the desired algorithms. For example, curl --ciphers "CALG_SHA1:CALG_RSA_SIGN:CALG_RSA_KEYX:CALG_AES_128:CALG_DH_EPHEM" https://github.com The specific names come from wincrypt.h Closes #2630
