From 2e5f198d9440e508be13cdbad6e3f3ab47898037 Mon Sep 17 00:00:00 2001

Subject: [PATCH] x509: detect loop in certificate chain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There can be a loop in a certificate chain, when multiple CA
certificates are cross-signed with each other, such as A → B, B → C,
and C → A. Previously, the verification logic was not capable of
handling this scenario while sorting the certificates in the chain in
_gnutls_sort_clist, resulting in an assertion failure. This patch
properly detects such loop and aborts further processing in a graceful
manner.

Subject: [PATCH] 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] cipher: add restriction on CCM tag length under FIPS mode
This change prohibits any use of tag length other than 4, 6, 8, 10,
12, 14, and 16 bytes in CCM used under FIPS mode, in accordance with
SP800-38C A.1. While use of tag lengths smaller than 8 bytes is not
recommended, we simply allow 4 and 6 bytes tags for now.

Subject: [PATCH] fips: Zeroize temporary values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The standard says "temporary value(s) generated during the integrity
test of the module's software […] shall be zeroised from the module upon
completion of the integrity test".
That includes the computed HMAC value, which is currently not zeroized
after the test. Add explicit calls to gnutls_memset() to fix that.

Subject: [PATCH] _gnutls_decrypt_pbes1_des_md5_data: use public crypto API
This is a follow-up of e7f9267342bc2231149a640163c82b63c86f1dfd. In
the decryption code path with PBES1, algorithm checks for FIPS was not
applied, because it used internal functions that bypass those checks.

Subject: [PATCH] nettle: mark non-compliant RSA-PSS salt length to be
not-approved
According to FIPS 186-5 5.4, the salt length must be in the range
between 0 and the hash length inclusive. While the use of those salt
lengths is still allowed for compatibility, it is reported as
non-approved operation through FIPS service indicator.

Subject: [PATCH] fips: provide function to manually run FIPS self-tests
FIPS140-3 IG 10.3.E Periodic Self-Testing says:
At security levels 1 and 2, acceptable means for initiating the
periodic self-tests include a provided service, resetting, rebooting
or power cycling.
Neither resetting, rebooting, nor power-cycling is suitable because
those involve operations outside of the module. Therefore this patch
adds a new API to manually run the substance of FIPS140 self-tests.

From: Richard Costa <richard.costa@suse.com>
Date: Sat, 9 Jul 2022 00:50:21 +0000
Subject: [PATCH] Add self-test code inside a FIPS context
Self-test code exercise lots of different FIPS-related code with
side-effects. So, in order to prevent it from losing information when
executing inside another context, we create an appropriated one.
If the self-test fails, then the library is placed in error state, so it
doesn't matter for other contexts.

Subject: [PATCH 2/3] handshake: do not reset KTLS enablement in
gnutls_handshake
As gnutls_handshake can be repeatedly called upon non-blocking setup,
we shouldn't try to call setsockopt for KTLS upon every call.

Subject: [PATCH 3/3] ktls: _gnutls_ktls_enable: fix GNUTLS_KTLS_SEND
calculation
Previously, if the first setsockopt for GNUTLS_KTLS_RECV fails and the
same socket is used for both sending and receiving, GNUTLS_KTLS_SEND
was unconditionally set. This fixes the conditions and also adds more
logging.

If gnutls_transport_set_pull_function or

Subject: [PATCH] rsa-psk: minimize branching after decryption
This moves any non-trivial code between gnutls_privkey_decrypt_data2
and the function return in _gnutls_proc_rsa_psk_client_kx up until the
decryption. This also avoids an extra memcpy to session->key.key.

Perform SP800 56A (rev 3) 5.6.2.1.4 Owner Assurance of Pair-wise
Consistency check, even if we only support ephemeral DH, as it is
required by FIPS 140-3 IG 10.3.A.
