non-overlapping *in and *out buffers as we're already implementing the "in place (un)wrapping" algorithms as given in RFC 3394. This removes a gratuitous API difference to OpenSSLin these undocumented functions. Found while working on wycheproof regress tests. ok beck jsing

2018-11-06Include TLSv1.3 in version handling code.Joel Sing
This is effectively a no-op, since most of the code clamps to the maximum version supported by the TLS method (which are still at TLSv1.2). ok beck@ bluhm@ tb@

2018-11-06Start working towards adding feature flags (rather than anti-feature flags)Joel Sing
for LibreSSL. Add a (commented out) feature flag for TLSv1.3 and define the OPENSSL_NO_TLS1_3 anti-feature flag based on the feature flag. ok beck@ bluhm@ tb@

2018-11-05Rename the TLS Supported Elliptic Curves extension to Supported Groups.Joel Sing
RFC 7919 renamed the Supported Elliptic Curves TLS extension to Supported Groups and redefined it to include finite field DH (FFDH) in addition to elliptic curve DH (ECDH). As such, rename the TLS extension and change the associated code to refer to groups rather than curves. ok beck@ tb@

2018-11-05Implement coordinate blinding for EC_POINT.Theo Buehler
Based on OpenSSL commit 875ba8b21ecc65ad9a6bdc66971e50 by Billy Brumley, Sohaib ul Hassan and Nicola Tuveri. ok beck jsing commit 875ba8b21ecc65ad9a6bdc66971e50461660fcbb Author: Sohaib ul Hassan <soh.19.hassan@gmail.com> Date: Sat Jun 16 17:07:40 2018 +0300 Implement coordinate blinding for EC_POINT This commit implements coordinate blinding, i.e., it randomizes the representative of an elliptic curve point in its equivalence class, for prime curves implemented through EC_GFp_simple_method, EC_GFp_mont_method, and EC_GFp_nist_method. This commit is derived from the patch https://marc.info/?l=openssl-dev&m=131194808413635 by Billy Brumley. Coordinate blinding is a generally useful side-channel countermeasure and is (mostly) free. The function itself takes a few field multiplicationss, but is usually only necessary at the beginning of a scalar multiplication (as implemented in the patch). When used this way, it makes the values that variables take (i.e., field elements in an algorithm state) unpredictable. For instance, this mitigates chosen EC point side-channel attacks for settings such as ECDH and EC private key decryption, for the aforementioned curves. For EC_METHODs using different coordinate representations this commit does nothing, but the corresponding coordinate blinding function can be easily added in the future to extend these changes to such curves.

2018-11-05Clean up the code that checks if we can choose an EC cipher suite.Joel Sing
The tls1_check_ec_tmp_key() function is now rather misnamed, so just inline the code. Also, rather than running tls1_get_shared_curve() once per EC cipher suite, we can run it once at the start of the ssl3_choose_cipher() function. ok bluhm@ tb@

currently exist in OpenSSL - comment out that ones that we do not already define. Some OPENSSL_NO_* flags that we define have been removed from OpenSSL (and code that depended on these to know when features are not available now think that the features have been enabled...). We keep these defined but in their own separate group. ok bluhm@ tb@

2018-10-24Make more of libssl's record layer state internal.Joel Sing
In January 2017, we changed large amounts of libssl's data structures to be non-visible/internal, however intentionally left things that the software ecosystem was needing to use. The four or so applications that reached into libssl for record layer related state now implement alternative code. As such, make these data structures internal. ok tb@
