The function SSL_set_session_ticket_ext sets the ticket data to be sent in the ClientHello. This is useful for EAP-FAST. This commit adds a test to ensure that when this function is called the expected ticket data actually appears in the ClientHello. Reviewed-by: Viktor Dukhovni <viktor@openssl.org>

This flag was not set anywhere within the codebase (only read). It could only be set by an app reaching directly into s->s3->flags and setting it directly. However that method became impossible when libssl was opaquified. Even in 1.0.2/1.0.1 if an app set the flag directly it is only relevant to ssl3_connect(), which calls SSL_clear() during initialisation that clears any flag settings. Therefore it could take effect if the app set the flag after the handshake has started but before it completed. It seems quite unlikely that any apps really do this (especially as it is completely undocumented). The purpose of the flag is suppress flushing of the write bio on the client side at the end of the handshake after the client has written the Finished message whilst resuming a session. This enables the client to send application data as part of the same flight as the Finished message. This flag also controls the setting of a second flag SSL3_FLAGS_POP_BUFFER. There is an interesting comment in the code about this second flag in the implementation of ssl3_write: /* This is an experimental flag that sends the * last handshake message in the same packet as the first * use data - used to see if it helps the TCP protocol during * session-id reuse */ It seems the experiment did not work because as far as I can tell nothing is using this code. The above comment has been in the code since SSLeay. This commit removes support for SSL3_FLAGS_DELAY_CLIENT_FINISHED, as well as the associated SSL3_FLAGS_POP_BUFFER.

Removed ability to set ex_data impl at runtime. This removed these three functions: const CRYPTO_EX_DATA_IMPL *CRYPTO_get_ex_data_implementation(void); int CRYPTO_set_ex_data_implementation(const CRYPTO_EX_DATA_IMPL *i); int CRYPTO_ex_data_new_class(void); It is no longer possible to change the ex_data implementation at runtime. (Luckily those functions were never documented :) Also removed the ability to add new exdata "classes." We don't believe this received much (if any) use, since you can't add it to OpenSSL objects, and there are probably better (native) methods for developers to add their own extensible data, if they really need that. Replaced the internal hash table (of per-"class" stacks) with a simple indexed array. Reserved an index for "app" application. Each API used to take the lock twice; now it only locks once. Use local stack storage for function pointers, rather than malloc, if possible (i.e., number of ex_data items is under a dozen). Make CRYPTO_EX_DATA_FUNCS opaque/internal. Also fixes RT3710; index zero is reserved. Reviewed-by: Richard Levitte <levitte@openssl.org>

The function X509_verify_cert checks the value of |ctx->chain| at the beginning, and if it is NULL then it initialises it, along with the value of ctx->untrusted. The normal way to use X509_verify_cert() is to first call X509_STORE_CTX_init(); then set up various parameters etc; then call X509_verify_cert(); then check the results; and finally call X509_STORE_CTX_cleanup(). The initial call to X509_STORE_CTX_init() sets |ctx->chain| to NULL. The only place in the OpenSSL codebase where |ctx->chain| is set to anything other than a non NULL value is in X509_verify_cert itself. Therefore the only ways that |ctx->chain| could be non NULL on entry to X509_verify_cert is if one of the following occurs: 1) An application calls X509_verify_cert() twice without re-initialising in between. 2) An application reaches inside the X509_STORE_CTX structure and changes the value of |ctx->chain| directly. With regards to the second of these, we should discount this - it should not be supported to allow this. With regards to the first of these, the documentation is not exactly crystal clear, but the implication is that you must call X509_STORE_CTX_init() before each call to X509_verify_cert(). If you fail to do this then, at best, the results would be undefined. Calling X509_verify_cert() with |ctx->chain| set to a non NULL value is likely to have unexpected results, and could be dangerous. This commit changes the behaviour of X509_verify_cert() so that it causes an error if |ctx->chain| is anything other than NULL (because this indicates that we have not been initialised properly). It also clarifies the associated documentation. This is a follow up commit to CVE-2015-1793. Reviewed-by: Stephen Henson <steve@openssl.org>

During certificate verfification, OpenSSL will attempt to find an alternative certificate chain if the first attempt to build such a chain fails. An error in the implementation of this logic can mean that an attacker could cause certain checks on untrusted certificates to be bypassed, such as the CA flag, enabling them to use a valid leaf certificate to act as a CA and "issue" an invalid certificate. This occurs where at least one cert is added to the first chain from the trust store, but that chain still ends up being untrusted. In that case ctx->last_untrusted is decremented in error.
