2022-10-07Partial revert and reimplement "Enable brainpool curves for TLS1.3"Matt Caswell
This partially reverts commit 0a10825a0 in order to reimplement it in a simpler way in the next commit. The reverted aspects are all related to the TLSv1.3 brainpool curves in the supported_groups extension. Rather than special casing the handling of these curves we simply add new entries to the groups table to represent them. They can then be handled without any additional special casing. This makes the code simpler to maintain. Reviewed-by: Tomas Mraz <tomas@openssl.org> Reviewed-by: Dmitry Belyavskiy <beldmit@gmail.com> (Merged from https://github.com/openssl/openssl/pull/19315)

2022-10-05Stop raising ERR_R_MALLOC_FAILURE in most placesRichard Levitte
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and at least handle the file name and line number they are called from, there's no need to report ERR_R_MALLOC_FAILURE where they are called directly, or when SSLfatal() and RLAYERfatal() is used, the reason `ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`. There were a number of places where `ERR_R_MALLOC_FAILURE` was reported even though it was a function from a different sub-system that was called. Those places are changed to report ERR_R_{lib}_LIB, where {lib} is the name of that sub-system. Some of them are tricky to get right, as we have a lot of functions that belong in the ASN1 sub-system, and all the `sk_` calls or from the CRYPTO sub-system. Some extra adaptation was necessary where there were custom OPENSSL_malloc() wrappers, and some bugs are fixed alongside these changes.

2021-05-15Promote SSL_get_negotiated_group() for non-TLSv1.3Benjamin Kaduk
It can be useful to know what group was used for the handshake's key exchange process even on non-TLS 1.3 connections. Allow this API, new in OpenSSL 3.0.0, to be used on other TLS versions as well. Since pre-TLS-1.3 key exchange occurs only on full handshakes, this necessitates adding a field to the SSL_SESSION object to carry the group information across resumptions. The key exchange group in the SSL_SESSION can also be relevant in TLS 1.3 when the resumption handshake uses the "psk_ke" key-exchange mode, so also track whether a fresh key exchange was done for TLS 1.3. Since the new field is optional in the ASN.1 sense, there is no need to increment SSL_SESSION_ASN1_VERSION (which incurs strong incompatibility churn).

2021-02-04Remove some TODO(OpenSSL1.2) referencesMatt Caswell
We had a couple of stray references to OpenSSL1.2 in libssl. We just reword the comments to remove those references without changing any behaviour. The first one in t1_lib.c is a technical non-compliance in the TLSv1.3 spec where, under some circumstances, we offer DSA sigalgs even in a ClientHello that eventually negotiates TLSv1.3. We explicitly chose to accept this behaviour in 1.1.1 and we're not planning to change it for 3.0. The second one in s3_lib.c is regarnding the behaviour of SSL_set_tlsext_host_name(). Technically you shouldn't be able to call this from a server - but we allow it and just ignore it rather than raising an error. The TODO suggest we consider raising an error instead. However, with 3.0 we are trying to minimise breaking changes so I suggest not making this change now.
