- tests: Fix the SRP test that fails with SIGPIPE signal return due
to a socket being closed before using it.
* Add gnutls-srp-test-SIGPIPE.patch

- Update to version 3.8.1:
* libgnutls: ClientHello extensions are randomized by default
To make fingerprinting harder, TLS extensions in ClientHello
messages are shuffled. As this behavior may cause compatibility
issue with legacy applications that do not accept the last
extension without payload, the behavior can be reverted with the
%NO_SHUFFLE_EXTENSIONS priority keyword.
* libgnutls: Add support for RFC 9258 external PSK importer.
This enables to deploy the same PSK across multiple TLS versions
(TLS 1.2 and TLS 1.3) in a secure manner. To use, the application
needs to set up a callback that formats the PSK identity using
gnutls_psk_format_imported_identity().
* libgnutls: %GNUTLS_NO_EXTENSIONS has been renamed to
%GNUTLS_NO_DEFAULT_EXTENSIONS.
* libgnutls: Add additional PBKDF limit checks in FIPS mode as
defined in SP 800-132. Minimum salt length is 128 bits and
minimum iterations bound is 1000 for PBKDF in FIPS mode.
* libgnutls: Add a mechanism to control whether to enforce extended
master secret (RFC 7627). FIPS 140-3 mandates the use of TLS
session hash (extended master secret, EMS) in TLS 1.2. To enforce
this, a new priority keyword %FORCE_SESSION_HASH is added and if
it is set and EMS is not set, the peer aborts the connection. This
behavior is the default in FIPS mode, though it can be overridden
through the configuration file with the "tls-session-hash" option.
In either case non-EMS PRF is reported as a non-approved operation
through the FIPS service indicator.
