* Add some missing statics.jsing2018-08-271-3/+3

* Clean up handshake message start/finish functions.jsing2018-08-241-39/+3
| | | | | | | | Now that all handshake messages are created using CBB, remove the non-CBB ssl3_handshake_msg_start()/ssl3_handshake_msg_finish() functions. Rename the CBB variants by dropping the _cbb suffix. ok bcook@ inoguchi@ tb@
* Remove the three remaining single DES cipher suites.jsing2018-06-021-49/+1
| | | | | | | | | These are insecure and should not be used - furthermore, we would should not have been allowing their negotiation with TLSv1.2 (as noted by Robert Merget, Juraj Somorovsky and Simon Friedberger). Removing these cipher suites also fixes this issue. ok beck@ inoguchi@
* Nuke SSL3_FLAGS_DELAY_CLIENT_FINISHED and SSL3_FLAGS_POP_BUFFER.jsing2018-04-071-47/+4
| | | | | | | These flags enabled experimental behaviour in the write path, which nothing uses. Removing this code greatly simplifies ssl3_write(). ok beck@ inoguchi@ sthen@ tb@
* Provide SSL_CTX_get_min_proto_version and SSL_CTX_get_max_proto_versionjca2018-03-151-1/+13
| | | | | | | | | We already provided the setters, so also provide the getters like OpenSSL does. Addition prompted by the use of those functions in recent openvpn releases. manpage diff from schwarze@ (thanks!) with input from jsing@, ok tb@ jsing@
* Provide SSL_CTX_get_tlsext_status_cb() and SSL_CTX_get_tlsext_status_arg().jsing2018-02-171-1/+15

* Convert ssl3_put_cipher_by_char() to CBB.jsing2018-01-271-9/+26
| | | | | | | While here make the CBS usage in ssl3_get_cipher_by_char() more consistent with other code. ok inoguchi@
* Convert ssl3_send_change_cipher_spec() to use CBB and make it handle DTLS,jsing2017-10-081-3/+9
| | | | | | which allows us to drop dtls1_send_change_cipher_spec() entirely. ok inoguchi@
* Annotate some API-side memory leaks for future resolution.jsing2017-09-251-1/+3

* ECDHE-RSA-DES-CBC3-SHA should not be marked HIGH.jsing2017-08-281-2/+2
| | | | Spotted by Andreas Bartelt <obsd at bartula dot de>
* Remove the original (pre-IETF) chacha20-poly1305 cipher suites.jsing2017-08-281-52/+1
| | | | | | | | | | Support for the IETF standardised chacha20-poly1305 cipher suites was added 16 months ago, which means they exist in both of the currently supported OpenBSD releases. Also prompted by Andreas Bartelt <obsd at bartula dot de>. ok beck@ doug@
* Remove NPN support.jsing2017-08-121-5/+1
| | | | | | | | | | | | | NPN was never standardised and the last draft expired in October 2012. ALPN was standardised in July 2014 and has been supported in LibreSSL since December 2014. NPN has also been removed from Chromium in May 2016. TLS clients and servers that try to use/enable NPN will fail gracefully and fallback to the default protocol, since it will essentially appear that the otherside does not support NPN. At some point in the future we will actually remove the NPN related symbols entirely. ok bcook@ beck@ doug@

* Clean up the EC key/curve configuration handling.jsing2017-08-101-44/+14
| | | | | | | | | | | | | | | | | | | | | | Over the years OpenSSL grew multiple ways of being able to specify EC keys (and/or curves) for use with ECDH and ECDHE key exchange. You could specify a static EC key (SSL{_CTX,}_set_tmp_ecdh()), use that as a curve and generate ephemeral keys (SSL_OP_SINGLE_ECDH_USE), provide the EC key via a callback that was provided with insufficient information (SSL{_CTX,}_set_tmp_ecdh_cb()) or enable automatic selection and generation of EC keys via SSL{_CTX,}_set_ecdh_auto(). This complexity leads to problems (like ECDHE not being enabled) and potential weird configuration (like being able to do ECDHE without the ephemeral part...). We no longer support ECDH and ECDHE can be disabled by removing ECDHE ciphers from the cipher list. As such, permanently enable automatic EC curve selection and generation, effectively disabling all of the configuration knobs. The only exception is the SSL{_CTX,}_set_tmp_ecdh() functions, which retain part of their previous behaviour by configuring the curve of the given EC key as the only curve being enabled. Everything else becomes a no-op. ok beck@ doug@

This also changes the default list of EC curves to be X25519, P-256 and P-384. If you want others (such a brainpool) you need to configure this yourself. Inspired by parts of BoringSSL and OpenSSL. ok beck@
