2015-11-13openssl: Free modules on cleanupSebastian Pohlschmidt
Curl_ossl_init calls OPENSSL_load_builtin_modules() but Curl_ossl_cleanup doesn't make a call to free these modules. Bug: https://github.com/bagder/curl/issues/526
2015-11-13cleanup: general removal of TODO (and similar) commentsDaniel Stenberg
They tend to never get updated anyway so they're frequently inaccurate and we never go back to revisit them anyway. We document issues to work on properly in KNOWN_BUGS and TODO instead.
2015-11-13openssl: remove #if check for 0.9.7 for ENGINE_load_private_keyDaniel Stenberg
2015-11-13openssl: all supported versions have X509_STORE_set_flagsDaniel Stenberg
Simplify by removing #ifdefs and macros
2015-11-13openssl: remove 0.9.3 checkDaniel Stenberg
2015-11-13openssl: remove #ifdefs for < 0.9.5 supportDaniel Stenberg
We only support >= 0.9.7
2015-11-13lib/vtls/openssl: remove unused traces of yassl ifdefsDaniel Stenberg
2015-11-10BoringSSL: Work with stricter BIO_get_mem_data()Douglas Creager
BoringSSL implements `BIO_get_mem_data` as a function, instead of a macro, and expects the output pointer to be a `char **`. We have to add an explicit cast to grab the pointer as a `const char **`. Closes #524
2015-10-29mbedtls: fix "Structurally dead code"Daniel Stenberg

2015-10-29mbedtls: fix "Logically dead code"Daniel Stenberg
CID 1332128
2015-10-29Revert "openssl: engine: remove double-free"Daniel Stenberg
This reverts commit 370ee919b37cc9a46c36428b2bb1527eae5db2bd. Issue #509 has all the details but it was confirmed that the crash was not due to this, so the previous commit was wrong.
2015-10-27openssl: engine: remove double-freeDaniel Stenberg
After a successful call to SSL_CTX_use_PrivateKey(), we must not call EVP_PKEY_free() on the key. Reported-by: nased0 Closes #509
2015-10-23polarssl/mbedtls: fix name space pollutionDaniel Stenberg
Global private symbols MUST start with Curl_!
2015-10-23mbedTLS: THREADING_SUPPORT compilation fixDmitry S. Baikov
Closes #505
2015-10-22mbedtls:new profile with RSA min key len = 1024.m-gardet
Closes #502
2015-10-20vtls: fix compiler warning for TLS backends without sha256Daniel Stenberg
... noticed with mbedTLS.
2015-10-20vtls: added support for mbedTLSJonas Minnberg
closes #496
2015-10-11openssl: Fix set up of pkcs12 certificate verification chainErik Johansson
sk_X509_pop will decrease the size of the stack which means that the loop would end after having added only half of the certificates. Also make sure that the X509 certificate is freed in case SSL_CTX_add_extra_chain_cert fails.
2015-09-28openssl: Fix algorithm initMichael Kalinin
- Change algorithm init to happen after OpenSSL config load. Additional algorithms may be available due to the user's config so we initialize the algorithms after the user's config is loaded. Bug: https://github.com/bagder/curl/issues/447 Reported-by: Denis Feklushkin
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. Signed-off-by: Mike Crowe <mac@mcrowe.com>
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
Add a "pinnedpubkey" section to the "Server Certificate" verbose Bug: https://github.com/bagder/curl/issues/410 Reported-by: W. Mark Kubacki Closes #430 Closes #410
2015-09-19openssl: don't output certinfo dataAlessandro Ghedini
2015-09-19openssl: refactor certificate parsing to use OpenSSL memory BIOAlessandro Ghedini
Fixes #427
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
2015-09-18nss: check return values of NSS functionsKamil Dudka
2015-09-17openssl: build with < 0.9.8Daniel Stenberg
... without sha256 support and no define saying so. Reported-by: Rajkumar Mandal
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
2015-08-01schannel: Fix compilation warning from commit 7a8e861a56Steve Holme
schannel.c:1125:5: warning: missing initializer for field 'dwMinorVersion' of 'OSVERSIONINFOEX' [-Wmissing-field-initializers
2015-07-24openssl: work around MSVC warningMarcel Raad
MSVC 12 complains: lib\vtls\openssl.c(1554): warning C4701: potentially uninitialized local variable 'verstr' used It's a false positive, but as it's normally not, I have enabled warning-as-error for that warning.
2015-07-22schannel: Replace deprecated GetVersion with VerifyVersionInfoMarcel Raad
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.

2015-07-14openssl: VMS support for SHA256John Malmberg
setup-vms.h: More symbols for SHA256, hacks for older VAX openssl.h: Use OpenSSL OPENSSL_NO_SHA256 macro to allow building on VAX. openssl.c: Use OpenSSL version checks and OPENSSL_NO_SHA256 macro to allow building on VAX and 64 bit VMS.

2015-06-18openssl: fix use of uninitialized bufferDaniel Stenberg
Make sure that the error buffer is always initialized and simplify the use of it to make the logic easier. Bug: https://github.com/bagder/curl/issues/318 Reported-by: sneis
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
ERR_error_string_n() was introduced in 0.9.6, no need to #ifdef anymore
2015-06-05openssl: removed USERDATA_IN_PWD_CALLBACK kludgeDaniel Stenberg
Code for OpenSSL 0.9.4 serves no purpose anymore!
2015-06-05openssl: remove SSL_get_session()-using codeDaniel 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.
