2018-04-23curl_global_sslset: always provide available backendsChristian Schmitz
Closes #2499
2018-04-23schannel: fix build error on targets <= XPArchangel_SDY
- Use CRYPT_STRING_HEX instead of CRYPT_STRING_HEXRAW since XP doesn't support the latter. Ref: https://github.com/curl/curl/pull/2376#issuecomment-382153668 Closes https://github.com/curl/curl/pull/2504
2018-04-20openssl: fix subjectAltName check on non-ASCII platformsStephan Mühlstrasser
Curl_cert_hostcheck operates with the host character set, therefore the ASCII subjectAltName string retrieved with OpenSSL must be converted to the host encoding before comparison. Closes #2493
2018-04-20openssl: Add support for OpenSSL 1.1.1 verbose-mode trace messagesJay Satiro
- Support handling verbose-mode trace messages of type SSL3_RT_INNER_CONTENT_TYPE, SSL3_MT_ENCRYPTED_EXTENSIONS, SSL3_MT_END_OF_EARLY_DATA, SSL3_MT_KEY_UPDATE, SSL3_MT_NEXT_PROTO, SSL3_MT_MESSAGE_HASH Reported-by: iz8mbw@users.noreply.github.com Fixes https://github.com/curl/curl/issues/2403
2018-04-18schannel: add support for CURLOPT_CAINFODan McNulty
- Move verify_certificate functionality in schannel.c into a new file called schannel_verify.c. Additionally, some structure defintions from schannel.c have been moved to schannel.h to allow them to be used in schannel_verify.c. - Make verify_certificate functionality for Schannel available on all versions of Windows instead of just Windows CE. verify_certificate will be invoked on Windows CE or when the user specifies CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER. - In verify_certificate, create a custom certificate chain engine that exclusively trusts the certificate store backed by the CURLOPT_CAINFO file. - doc updates of --cacert/CAINFO support for schannel - Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString when available. This implements a TODO in schannel.c to improve handling of multiple SANs in a certificate. In particular, all SANs will now be searched instead of just the first name. - Update tool_operate.c to not search for the curl-ca-bundle.crt file when using Schannel to maintain backward compatibility. Previously, any curl-ca-bundle.crt file found in that search would have been ignored by Schannel. But, with CAINFO support, the file found by that search would have been used as the certificate store and could cause issues for any users that have curl-ca-bundle.crt in the search path. - Update url.c to not set the build time CURL_CA_BUNDLE if the selected SSL backend is Schannel. We allow setting CA location for schannel only when explicitly specified by the user via CURLOPT_CAINFO / --cacert. - Add new test cases 3000 and 3001. These test cases check that the first and last SAN, respectively, matches the connection hostname. New test certificates have been added for these cases. For 3000, the certificate prefix is Server-localhost-firstSAN and for 3001, the certificate prefix is Server-localhost-secondSAN. - Remove TODO 15.2 (Add support for custom server certificate validation), this commit addresses it. Closes https://github.com/curl/curl/pull/1325
2018-04-17schannel: fix warningJay Satiro
- Fix warning 'integer from pointer without a cast' on 3rd arg in CertOpenStore. The arg type HCRYPTPROV may be a pointer or integer type of the same size. Follow-up to e35b025. Caught by Marc's CI builds.
2018-04-17schannel: add client certificate authenticationArchangel_SDY
Users can now specify a client certificate in system certificates store explicitly using expression like `--cert "CurrentUser\MY\<thumbprint>"` Closes #2376
2018-04-15all: Refactor malloc+memset to use callocDaniel Gustafsson
When a zeroed out allocation is required, use calloc() rather than malloc() followed by an explicit memset(). The result will be the same, but using calloc() everywhere increases consistency in the codebase and avoids the risk of subtle bugs when code is injected between malloc and memset by accident. Closes https://github.com/curl/curl/pull/2497
2018-04-08build: cleanup to fix clang warnings/errorsDaniel Stenberg
unit1309 and vtls/gtls: error: arithmetic on a null pointer treated as a cast from integer to pointer is a GNU extension Reported-by: Rikard Falkeborn Fixes #2466 Closes #2468
2018-04-06Revert "openssl: Don't add verify locations when verifypeer==0"Gaurav Malhotra
This reverts commit dc85437736e1fc90e689bb1f6c51c8f1aa9430eb. libcurl (with the OpenSSL backend) performs server certificate verification even if verifypeer == 0 and the verification result is available using CURLINFO_SSL_VERIFYRESULT. The commit that is being reverted caused the CURLINFO_SSL_VERIFYRESULT to not have useful information for the verifypeer == 0 use case (it would always have X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY). Closes #2451
2018-04-06tls: fix mbedTLS 2.7.0 build + handle sha256 failuresWyatt O'Day
(mbedtls 2.70 compiled with MBEDTLS_DEPRECATED_REMOVED) Closes #2453
2018-04-04openssl: provide defines for argument typecasts to build warning-freeDaniel Stenberg

2018-02-28unit1309: fix warning on Windows x64Marcel Raad
When targeting x64, MinGW-w64 complains about conversions between 32-bit long and 64-bit pointers. Fix this by reusing the GNUTLS_POINTER_TO_SOCKET_CAST / GNUTLS_SOCKET_TO_POINTER_CAST logic from gtls.c, moving it to warnless.h as CURLX_POINTER_TO_INTEGER_CAST / CURLX_INTEGER_TO_POINTER_CAST. Closes https://github.com/curl/curl/pull/2341

2018-02-06openssl: Don't add verify locations when verifypeer==0Patrick Schlangen
When peer verification is disabled, calling SSL_CTX_load_verify_locations is not necessary. Only call it when verification is enabled to save resources and increase performance. Closes #2290

2018-01-25openssl: fix pinned public key build error in FIPS modeMcDonough, Tim
Here is a version that should work with all versions of openssl 0.9.7 through 1.1.0. Links to the docs: https://www.openssl.org/docs/man1.0.2/crypto/EVP_DigestInit.html https://www.openssl.org/docs/man1.1.0/crypto/EVP_DigestInit.html At the very bottom of the 1.1.0 documentation there is a history section that states, " stack allocated EVP_MD_CTXs are no longer supported." If EVP_MD_CTX_create and EVP_MD_CTX_destroy are not defined, then a simple mapping can be used as described here: https://wiki.openssl.org/index.php/Talk:OpenSSL_1.1.0_Changes Closes #2258

2018-01-05build: remove HAVE_LIMITS_H checkJay Satiro
.. because limits.h presence isn't optional, it's required by C89. Ref: http://port70.net/~nsz/c/c89/c89-draft.html#2.2.4.2 Closes https://github.com/curl/curl/pull/2215
2018-01-03openssl: fix memory leak of SSLKEYLOGFILE filenameJay Satiro
- Free the copy of SSLKEYLOGFILE env returned by curl_getenv during ossl initialization. Caught by ASAN.
2017-12-12vtls: replaced getenv() with curl_getenv()dmitrykos
Fixed undefined symbol of getenv() which does not exist when compiling for Windows 10 App (CURL_WINDOWS_APP). Replaced getenv() with curl_getenv() which is aware of getenv() absence when CURL_WINDOWS_APP is defined. Closes #2171
2017-12-10openssl: Disable file buffering for Win32 SSLKEYLOGFILEJay Satiro
Prior to this change SSLKEYLOGFILE used line buffering on WIN32 just like it does for other platforms. However, the Windows CRT does not actually support line buffering (_IOLBF) and will use full buffering (_IOFBF) instead. We can't use full buffering because multiple processes may be writing to the file and that could lead to corruption, and since full buffering is the only buffering available this commit disables buffering for Windows SSLKEYLOGFILE entirely (_IONBF). Ref: https://github.com/curl/curl/pull/1346#issuecomment-350530901
2017-12-08openssl: improve data-pending check for https proxyJay Satiro
- Allow proxy_ssl to be checked for pending data even when connssl does not yet have an SSL handle. This change is for posterity. Currently there doesn't seem to be a code path that will cause a pending data check when proxyssl could have pending data and the connssl handle doesn't yet exist [1]. [1]: Recall that an https proxy connection starts out in connssl but if the destination is also https then the proxy SSL backend data is moved from connssl to proxyssl, which means connssl handle is temporarily empty until an SSL handle for the destination can be created. Ref: https://github.com/curl/curl/commit/f4a6238#commitcomment-24396542 Closes https://github.com/curl/curl/pull/1916

2017-10-25time: rename Curl_tvnow to Curl_nowDaniel Stenberg
... since the 'tv' stood for timeval and this function does not return a timeval struct anymore. Also, cleaned up the Curl_timediff*() functions to avoid typecasts and clean up the descriptive comments. Closes #2011
2017-10-25timediff: return timediff_t from the time diff functionsDaniel Stenberg
... to cater for systems with unsigned time_t variables. - Renamed the functions to curlx_timediff and Curl_timediff_us. - Added overflow protection for both of them in either direction for both 32 bit and 64 bit time_ts - Reprefixed the curlx_time functions to use Curl_* Reported-by: Peter Piekarski Fixes #2004 Closes #2005
2017-10-19vtls: change struct Curl_ssl `close' field name to `close_one'.Patrick Monnerat
On OS/400, `close' is an ASCII system macro that corrupts the code if not used in a context not targetting the close() system API.
2017-10-11openssl: don't use old BORINGSSL_YYYYMM macrosDavid Benjamin
Those were temporary things we'd add and remove for our own convenience long ago. The last few stayed around for too long as an oversight but have since been removed. These days we have a running BORINGSSL_API_VERSION counter which is bumped when we find it convenient, but 2015-11-19 was quite some time ago, so just check OPENSSL_IS_BORINGSSL. Closes #1979
2017-10-09openssl: enable PKCS12 support for !BoringSSLDaniel Stenberg

2017-10-03vtls: compare and clone ssl configs properlyMichael Kaufmann
Compare these settings in Curl_ssl_config_matches(): - verifystatus (CURLOPT_SSL_VERIFYSTATUS) - random_file (CURLOPT_RANDOM_FILE) - egdsocket (CURLOPT_EGDSOCKET) Also copy the setting "verifystatus" in Curl_clone_primary_ssl_config(), and copy the setting "sessionid" unconditionally. This means that reusing connections that are secured with a client certificate is now possible, and the statement "TLS session resumption is disabled when a client certificate is used" in the old advisory at https://curl.haxx.se/docs/adv_20170419.html is obsolete. Reviewed-by: Daniel Stenberg Closes #1917
2017-09-23ntlm: move NTLM_NEEDS_NSS_INIT define into core NTLM headerJay Satiro
.. and include the core NTLM header in all NTLM-related source files. Follow up to 6f86022. Since then http_ntlm checks NTLM_NEEDS_NSS_INIT but did not include vtls.h where it was defined. Closes https://github.com/curl/curl/pull/1911
2017-09-22ntlm: use strict order for SSL backend #if branchesViktor Szakats
With the recently introduced MultiSSL support multiple SSL backends can be compiled into cURL That means that now the order of the SSL One option would be to use the same SSL backend as was configured via `curl_global_sslset()`, however, NTLMv2 support would appear to be available only with some SSL backends. For example, when eb88d778e (ntlm: Use Windows Crypt API, 2014-12-02) introduced support for NTLMv1 using Windows' Crypt API, it specifically did *not* introduce NTLMv2 support using Crypt API at the same time. So let's select one specific SSL backend for NTLM support when compiled with multiple SSL backends, using a priority order such that we support NTLMv2 even if only one compiled-in SSL backend can be used for that.
