Subject: [PATCH 3/7] nettle/pk.c: Do not call gnutls_rnd() during self tests
When the library state is LIB_STATE_SELFTEST, use constant data instead
of calling gnutls_rnd(). This prevents the library to block if there is
insufficient entropy during FIPS self tests.

Subject: [PATCH 1/2] gnutls_int.h: make DECR_LEN neutral to signedness
DECR_LEN was previously implemented in a way that it first decrements
the given length and then checks whether the result is negative. This
requires the caller to properly coerce the length argument to a signed
integer, before invoking the macro.

Subject: [PATCH] nettle/rnd-fips: add FIPS 140-2 continuous RNG test
This adds a continuous random number generator test as defined in FIPS
140-2 4.9.2, by iteratively fetching fixed sized block from the system
and comparing consecutive blocks.

Nettle's RSA signing, encryption and decryption functions still
require randomness for blinding, so fallback to use a fixed buffer in
selftests where entropy might not be available.

Date: Thu, 3 Oct 2019 10:34:18 +0200
Subject: [PATCH 1/3] iov: _gnutls_iov_iter_next: return bytes instead of
blocks
This eliminates the need of special handling of final block. Also
adds more tests in exceptional cases.

Subject: [PATCH 3/3] gnutls_aead_cipher_{en,de}cryptv2: write back cached data
to buffers
Previously, those functions failed to write the output to the buffers
if the buffer length is not multiple of cipher block size. This makes
sure that the cached data is always flushed.

Subject: [PATCH] pkcs11: ignore login error when traversing tokens
If a token is a general access device, it is expected that login
attempt to that token returns error:
https://github.com/p11-glue/p11-kit/blob/master/trust/module.c#L852
On the other hand, _pkcs11_traverse_tokens treats the error as fatal
and stops iteration. This behavior prevents object search without
token specifier if such tokens are registered in the system.

From 1f6bbceeeeb613cf4d790874bdd1e917a7071159 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ext/session_ticket: avoid calling memcpy on overlapping
memory areas
In _gnutls_encrypt_session_ticket, ticket.encrypted_state is allocated
from ticket_data->data, thus those memory areas may overlap. Using
memcpy here leads to undefined behavior.
Spotted by valgrind run on ppc64le.
