2015-09-23gnutls: Report actual GnuTLS error message for certificate errorsMike Crowe
If GnuTLS fails to read the certificate then include whatever reason it provides in the failure message reported to the client. Signed-off-by: Mike Crowe <mac@mcrowe.com>
2015-09-22gnutls: Support CURLOPT_KEYPASSWDMike Crowe
The gnutls vtls back-end was previously ignoring any password set via CURLOPT_KEYPASSWD. Presumably this was because gnutls_certificate_set_x509_key_file did not support encrypted keys. gnutls now has a gnutls_certificate_set_x509_key_file2 function that does support encrypted keys. Let's determine at compile time whether the available gnutls supports this new function. If it does then use it to pass the password. If it does not then emit a helpful diagnostic if a password is set. This is preferable to the previous behaviour of just failing to read the certificate without giving a reason in that case.

2015-09-19vtls: Change designator name for server's pubkey hashJay Satiro
- Change the designator name we use to show the base64 encoded sha256 hash of the server's public key from 'pinnedpubkey' to 'public key hash'. Though the server's public key hash is only shown when comparing pinned public key hashes, the server's hash may not match one of the pinned.
2015-09-19ssl: add server cert's "sha256//" hash to verboseDaniel Hwang

2015-09-18nss: prevent NSS from incorrectly re-using a sessionKamil Dudka
Without this workaround, NSS re-uses a session cache entry despite the server name does not match. This causes SNI host name to differ from the actual host name. Consequently, certain servers (e.g. github.com) respond by 400 to such requests. Bug: https://bugzilla.mozilla.org/1202264

2015-09-04nss: do not directly access SSL_ImplementedCiphers[]Kamil Dudka
It causes dynamic linking issues at run-time after an update of NSS. Bug: https://lists.fedoraproject.org/pipermail/devel/2015-September/214117.html
2015-08-21openssl: handle lack of server cert when strict checking disabledAlessandro Ghedini
If strict certificate checking is disabled (CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST are disabled) do not fail if the server doesn't present a certificate at all. Closes #392

2015-07-17SSL: Add an option to disable certificate revocation checksJay Satiro
New tool option --ssl-no-revoke. New value CURLSSLOPT_NO_REVOKE for CURLOPT_SSL_OPTIONS. Currently this option applies only to WinSSL where we have automatic certificate revocation checking by default. According to the ssl-compared chart there are other backends that have automatic checking (NSS, wolfSSL and DarwinSSL) so we could possibly accommodate them at some later point.

2015-06-18openssl: fix build with BoringSSLDaniel Stenberg
OPENSSL_load_builtin_modules does not exist in BoringSSL. Regression from cae43a1
2015-06-17openssl: Fix build with openssl < ~ 0.9.8fPaul Howarth
The symbol SSL3_MT_NEWSESSION_TICKET appears to have been introduced at around openssl 0.9.8f, and the use of it in lib/vtls/openssl.c breaks builds with older openssls (certainly with 0.9.8b, which is the latest older version I have to try with).
2015-06-17schannel: schannel_recv overhaulJay Satiro
This commit is several drafts squashed together. The changes from each draft are noted below. If any changes are similar and possibly contradictory the change in the latest draft takes precedence. Bug: https://github.com/bagder/curl/issues/244 Reported-by: Chris Araman %% %% Draft 1 %% - return 0 if len == 0. that will have to be documented. - continue on and process the caches regardless of raw recv - if decrypted data will be returned then set the error code to CURLE_OK and return its count - if decrypted data will not be returned and the connection has closed (eg nread == 0) then return 0 and CURLE_OK - if decrypted data will not be returned and the connection *hasn't* closed then set the error code to CURLE_AGAIN --only if an error code isn't already set-- and return -1 - narrow the Win2k workaround to only Win2k %% %% Draft 2 %% - Trying out a change in flow to handle corner cases. %% %% Draft 3 %% - Back out the lazier decryption change made in draft2. %% %% Draft 4 %% - Some formatting and branching changes - Decrypt all encrypted cached data when len == 0 - Save connection closed state - Change special Win2k check to use connection closed state %% %% Draft 5 %% - Default to CURLE_AGAIN in cleanup if an error code wasn't set and the connection isn't closed. %% %% Draft 6 %% - Save the last error only if it is an unrecoverable error. Prior to this I saved the last error state in all cases; unfortunately the logic to cover that in all cases would lead to some muddle and I'm concerned that could then lead to a bug in the future so I've replaced it by only recording an unrecoverable error and that state will persist. - Do not recurse on renegotiation. Instead we'll continue on to process any trailing encrypted data received during the renegotiation only. - Move the err checks in cleanup after the check for decrypted data. In either case decrypted data is always returned but I think it's easier to understand when those err checks come after the decrypted data check. %% %% Draft 7 %% - Regardless of len value go directly to cleanup if there is an unrecoverable error or a close_notify was already received. Prior to this change we only acknowledged those two states if len != 0. - Fix a bug in connection closed behavior: Set the error state in the cleanup, because we don't know for sure it's an error until that time. - (Related to above) In the case the connection is closed go "greedy" with the decryption to make sure all remaining encrypted data has been decrypted even if it is not needed at that time by the caller. This is necessary because we can only tell if the connection closed gracefully (close_notify) once all encrypted data has been decrypted. - Do not renegotiate when an unrecoverable error is pending. %% %% Draft 8 %% - Don't show 'server closed the connection' info message twice. - Show an info message if server closed abruptly (missing close_notify).
2015-06-11schannel: Add support for optional client certificatesJoel Depooter
Some servers will request a client certificate, but not require one. This change allows libcurl to connect to such servers when using schannel as its ssl/tls backend. When a server requests a client certificate, libcurl will now continue the handshake without one, rather than terminating the handshake. The server can then decide if that is acceptable or not. Prior to this change, libcurl would terminate the handshake, reporting a SEC_I_INCOMPLETE_CREDENTIALS error.
2015-06-08openssl: LibreSSL and BoringSSL do not use TLS_client_methodJay Satiro
Although OpenSSL 1.1.0+ deprecated SSLv23_client_method in favor of TLS_client_method LibreSSL and BoringSSL didn't and still use SSLv23_client_method. Bug: https://github.com/bagder/curl/commit/49a6642#commitcomment-11578009 Reported-by: asavah@users.noreply.github.com
2015-06-07openssl: Fix verification of server-sent legacy intermediatesJay Satiro
- Try building a chain using issuers in the trusted store first to avoid problems with server-sent legacy intermediates. Prior to this change server-sent legacy intermediates with missing legacy issuers would cause verification to fail even if the client's CA bundle contained a valid replacement for the intermediate and an alternate chain could be constructed that would verify successfully. https://rt.openssl.org/Ticket/Display.html?id=3621&user=guest&pass=guest
2015-06-05openssl: removed error string #ifdefDaniel Stenberg

It was present for OpenSSL 0.9.5 code but we only support 0.9.7 or later.
2015-06-05openssl: remove dummy callback use from SSL_CTX_set_verify()Daniel Stenberg
The existing callback served no purpose.
2015-06-01curl_setup: Add macros for FOPEN_READTEXT, FOPEN_WRITETEXTJay Satiro
- Change fopen calls to use FOPEN_READTEXT instead of "r" or "rt" - Change fopen calls to use FOPEN_WRITETEXT instead of "w" or "wt" This change is to explicitly specify when we need to read/write text. Unfortunately 't' is not part of POSIX fopen so we can't specify it directly. Instead we now have FOPEN_READTEXT, FOPEN_WRITETEXT. Prior to this change we had an issue on Windows if an application that uses libcurl overrides the default file mode to binary. The default file mode in Windows is normally text mode (translation mode) and that's what libcurl expects.

SSLv23_client_method is deprecated starting in OpenSSL 1.1.0. The equivalent is TLS_client_method. https://github.com/openssl/openssl/commit/13c9bb3#diff-708d3ae0f2c2973b272b811315381557
2015-05-20gtls: don't fail on non-fatal alerts during handshakeDmitry Eremin-Solenikov
Stop curl from failing when non-fatal alert is received during handshake. This e.g. fixes lots of problems when working with https sites through proxies.
2015-05-19openssl: Use SSL_CTX_set_msg_callback and SSL_CTX_set_msg_callback_argBrian Prodoehl
BoringSSL removed support for direct callers of SSL_CTX_callback_ctrl and SSL_CTX_ctrl, so move to a way that should work on BoringSSL and OpenSSL. re #275

2015-05-04openssl: skip trace outputs for ssl_ver == 0Daniel Stenberg
The OpenSSL trace callback is wonderfully undocumented but given a journey in the source code, it seems the cases were ssl_ver is zero doesn't follow the same pattern and thus turned out confusing and misleading. For now, we skip doing any CURLINFO_TEXT logging on those but keep sending them as CURLINFO_SSL_DATA_OUT/IN. Also, I added direction to the text info and I edited some functions slightly.
