* Provide SSL_OP_NO_RENEGOTIATION and SSL_OP_ALLOW_CLIENT_RENEGOTIATION.jsing5 days1-1/+5
| | | | | | | | | | | | | | | | | | | | | | In January 2017 we added SSL_OP_NO_CLIENT_RENEGOTIATION, which results in a SSL_AD_NO_RENEGOTIATION fatal alert if a ClientHello message is seen on an active connection (client initiated renegotation). Then in May 2017 OpenSSL added SSL_OP_NO_RENEGOTIATION, which results in a SSL_AD_NO_RENEGOTIATION warning alert if a server receives a ClientHello on an active connection (client initiated renegotation), or a client receives a HelloRequest (server requested renegotation). This option also causes calls to SSL_renegotiate() and SSL_renegotiate_abbreviated() to fail. Then in 2021, OpenSSL also added SSL_OP_ALLOW_CLIENT_RENEGOTIATION, which trumps SSL_OP_NO_RENEGOTIATION but only for incoming ClientHello messages (apparently unsetting SSL_OP_NO_RENEGOTIATION is too hard). Provide SSL_OP_NO_RENEGOTIATION and SSL_OP_ALLOW_CLIENT_RENEGOTIATION, primarily to make life easier for ports. If SSL_OP_NO_CLIENT_RENEGOTIATION is set it will take precedence and render SSL_OP_ALLOW_CLIENT_RENEGOTIATION ineffective. The rest of the behaviour should match OpenSSL, with the exception of ClientHellos triggering fatal alerts instead of warnings. ok tb@
* const correct tls_session_secret_cb_fn()tb8 days1-2/+2
| | | | | | | | | Various ports throw a warning since their tls_session_secret_cb's signature doesn't match what we expect. Aligns us with OpenSSL 1.1. This is only useful for RFC 4851 EAP-FAST implementations and surprisingly it's undocumented. ok jsing

| | | | Nothing uses this and it collides with ALPN
* Add missing alert errors and error stringstb2024-10-091-1/+5
| | | | | | | | For every TLS alert there needs a corresponding error with error code having an offset of SSL_AD_REASON_OFFSET (aka 1000), otherwise the error stack fails to set the reason correctly. ok beck

* Prepare to provide SSL_CTX_set1_cert_store()tb2024-08-031-1/+4
| | | | | | | | | | | | | | | | SSL_CTX_set_cert_store() should have been called SSL_CTX_set0_cert_store() since it takes ownership of the store argument. Apparently a few people ran into the issue of not bumping the refcount themselves, leading to use after frees about 10 years ago. This is a quite rarely used API and there are no misuses in the ports tree, but since someone did the work of writing a diff, we can still add it. Needless to say that SSL_CTX_get_cert_store() obviously has the exact same issue and nobody seems to have thought of adding a get0 or get1 version to match...

* Prepare to provide SSL_CIPHER_get_handshake_digest()tb2024-07-141-1/+4
| | | | | | | Needed by newer freeradius. This is a straightforward implementation that essentially duplicates tls13_cipher_hash(). ok jsing

| | | | | | | Now that the SSL2 client hello support is gone, nothing uses this anymore, except that a few ports still need SSL2_VERSION. ok beck

* Remove SSL_CIPHER_get_by_{id,value}()tb2024-03-021-3/+1
| | | | | | | | | While this undocumented API would have been much nicer and saner than SSL_CIPHER_find(), nothing used this except for the exporter test. Let's get rid of it again. libssl uses ssl3_get_cipher_by_{id,value}() directly. ok jsing
* Export SSL_get_{peer_,}signature_type_nid()tb2024-03-021-5/+1
| | | | | | | | | Also move the prototypes to the correct header. Oversight reported by Frank Lichtenheld, thanks! Fixes https://github.com/libressl/openbsd/issues/147 ok jsing
* Remove GOST and STREEBOG support from libssl.beck2024-02-031-10/+1
| | | | | | | | | | | | | | | | | | This version of GOST is old and not anywhere close to compliant with modern GOST standards. It is also very intrusive in libssl and makes a mess everywhere. Efforts to entice a suitably minded anyone to care about it have been unsuccessful. At this point it is probably best to remove this, and if someone ever showed up who truly needed a working version, it should be a clean implementation from scratch, and have it use something closer to the typical API in libcrypto so it would integrate less painfully here. This removes it from libssl in preparation for it's removal from libcrypto with a future major bump ok tb@

* Provide the remaining QUIC API.jsing2022-08-211-1/+43
| | | | | | | While more work is still required, this is sufficient to get ngtcp2 to compile with QUIC and for curl to be able to make HTTP/3 requests. ok tb@
* Provide SSL_QUIC_METHOD.jsing2022-08-211-6/+145
| | | | | | | | | | | | | | | | | | | This provides SSL_QUIC_METHOD (aka ssl_quic_method_st), which allows for QUIC callback hooks to be passed to an SSL_CTX or SSL. This is largely ported/adapted from BoringSSL. It is worth noting that this struct is not opaque and the original interface exposed by BoringSSL differs to the one they now use. The original interface was copied by quictls and it appears that this API will not be updated to match BoringSSL. To make things even more challenging, at least one consumer does not use named initialisers, making code completely dependent on the order in which the function pointers are defined as struct members. In order to try to support both variants, the set_read_secret/set_write_secret functions are included, however they have to go at the end. ok tb@

* Add SSL_get_shared_{curve,group}()tb2022-08-171-2/+10
| | | | | | | | These are wrappers of SSL_ctrl() using the SSL_CTRL_GET_SHARED_GROUP control. Do not provide SSL_CTRL_GET_SHARED_CURVE since that is only mentioned in Net::SSLeay docs according to codesearch.debian.net. ok jsing
* Provide QUIC encryption levels.jsing2022-07-241-1/+12
| | | | | | | | | | | | QUIC wants to know what "encryption level" handshake messages should be sent at. Provide an ssl_encryption_level_t enum (via BoringSSL) that defines these (of course quictls decided to make this an OSSL_ENCRYPTION_LEVEL typedef, so provide that as well). Wire these through to tls13_record_layer_set_{read,write}_traffic_key() so that they can be used in upcoming commits. ok tb@
* Provide SSL_is_quic()jsing2022-07-171-2/+4
| | | | | | | | This function will allow code to know if the SSL connection is configured for use with QUIC or not. Also move existing SSL_.*quic.* functions under LIBRESSL_HAS_QUIC to prevent exposing them prematurely. ok beck@ tb@

* Do not ignore SSL_TLSEXT_ERR_FATAL from the ALPN callbacktb2021-09-101-1/+4
| | | | | | | | | | | | | | | | | | | As reported by Jeremy Harris, we inherited a strange behavior from OpenSSL, in that we ignore the SSL_TLSEXT_ERR_FATAL return from the ALPN callback. RFC 7301, 3.2 states: 'In the event that the server supports no protocols that the client advertises, then the server SHALL respond with a fatal "no_application_protocol" alert.' Honor this requirement and succeed only on SSL_TLSEXT_ERR_{OK,NOACK} which is the current behavior of OpenSSL. The documentation change is taken from OpenSSL 1.1.1 as well. As pointed out by jsing, there is more to be fixed here: - ensure that the same protocol is selected on session resumption - should the callback be called even if no ALPN extension was sent? - ensure for TLSv1.2 and earlier that the SNI has already been processed ok beck jsing
