gnutls-3.8.11

[Douglas R. Reno]

New point version

* Version 3.8.11 (released 2025-11-18)

** libgnutls: Fix stack overwrite in gnutls_pkcs11_token_init
   Reported by Luigino Camastra from Aisle Research. [GNUTLS-SA-2025-11-18,
   CVSS: low] [CVE-2025-9820]

** libgnutls: MAC algorithms for PSK binders is now configurable
   The previous implementation assumed HMAC-SHA256 to calculate the
   PSK binders. With the new gnutls_psk_allocate_client_credentials2()
   and gnutls_psk_allocate_server_credentials2() functions, the
   application can use other MAC algorithms such as HMAC-SHA384.

** libgnutls: Expose a new function to provide the maximum record send size
   A new function gnutls_record_get_max_send_size() has been added to
   determine the maximum size of a TLS record to be sent to the peer.

** libgnutls: Expose a new function to update keys without sending a KeyUpdate
   to the peer. A new function gnutls_handshake_update_receiving_key()
   has been added to allow updating the local receiving key without
   sending any KeyUpdate messages.

** libgnutls: PKCS#11 cryptographic provider configuration takes a token URI
   instead of a module path. To allow using a PKCS#11 module exposing
   multiple tokens, the "path" configuration keyword was replaced with
   the "url" keyword.

** libgnutls: Support crypto-auditing probe points
   crypto-auditing is a project to monitor which cryptographic
   operations are taking place in the library at run time, through
   eBPF. This adds necessary probe points for that, in public key
   cryptography and the TLS use-case. To enable this, run configure
   with --enable-crypto-auditing.

** build: The minimum version of Nettle has been updated to 3.10
   Given Nettle 3.10 is ABI compatible with 3.6 and includes several
   security relevant fixes, the library's minimum requirement of
   Nettle is updated to 3.10.

** build: The default priority file path is now constructed from sysconfdir
   Previously, the location of the default priority file was
   hard-coded to be /etc/gnutls/config. Now it takes into account of
   the --sysconfdir option given to the configure script.

** API and ABI modifications:
gnutls_psk_allocate_client_credentials2: New function
gnutls_psk_allocate_server_credentials2: New function
gnutls_record_get_max_send_size: New function
gnutls_handshake_update_receiving_key: New function
gnutls_audit_push_context: New function
gnutls_audit_pop_context: New function
gnutls_audit_current_context: New function
