From f09b7627a63defb1c55e9965fb05e0bbddb90247 Mon Sep 17 00:00:00 2001
From: Daiki Ueno <ueno@gnu.org>
Date: Tue, 6 Oct 2020 11:54:21 +0200
Subject: [PATCH] fips: use larger prime for DH self-tests
According to FIPS140-2 IG 7.5, the minimum key size of FFC through
2030 is defined as 2048 bits. This updates the relevant self-test
using ffdhe3072 defined in RFC 7919.

Subject: [PATCH 1/4] fips: add self-tests for HKDF
FIPS140-2 IG D.8 mandates self-test on approved KDF algorithms. As
the guidance only requires running a single instance of each KDF
mechanism, this only exercises HKDF-Extract and HKDF-Expand operations
with HMAC-SHA-256 as the underlying MAC.
Although HKDF is non-approved, it would be sensible to do that as it
will be approved in FIPS140-3.

Subject: [PATCH 3/4] fips: add self-tests for TLS-PRF
FIPS140-2 IG D.8 mandates self-tests on approved KDF algorithms. As
the guidance only requires to run a single instance of each KDF
mechanism, this only exercises TLS1.2 PRF with HMAC-SHA-256 as the
underlying MAC algorithm.

From cd509dac9e6d1bf76fd12c72c1fd61f1708c254a Mon Sep 17 00:00:00 2001
From: Daiki Ueno <ueno@gnu.org>
Date: Mon, 15 Aug 2022 09:39:18 +0900
Subject: [PATCH 2/2] accelerated: clear AVX bits if it cannot be queried
through XSAVE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The algorithm to detect AVX is described in 14.3 of "Intel® 64 and IA-32
Architectures Software Developer’s Manual".
GnuTLS previously only followed that algorithm when registering the
crypto backend, while the CRYPTOGAMS derived SHA code assembly expects
that the extension bits are propagated to _gnutls_x86_cpuid_s.

Subject: [PATCH] cert auth: filter out unsupported cert types from TLS 1.2 CR
When the server is advertising signature algorithms in TLS 1.2
CertificateRequest, it shouldn't send certificate_types not backed by
any of those algorithms.

Subject: [PATCH] x509/verify: treat SHA-1 signed CA in the trusted set
differently
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Suppose there is a certificate chain ending with an intermediate CA:
EE → ICA1 → ICA2. If the system trust store contains a root CA
generated with the same key as ICA2 but signed with a prohibited
algorithm, such as SHA-1, the library previously reported a
verification failure, though the situation is not uncommon during a
transition period of root CA.
This changes the library behavior such that the check on signature
algorithm will be skipped when examining the trusted root CA.
