<https://github.com/ARMmbed/mbedtls/releases/tag/v2.28.0>
"Mbed TLS 2.28 is a long-time support branch.
It will be supported with bug-fixes and security
fixes until end of 2024."
<https://github.com/ARMmbed/mbedtls/blob/development/BRANCHES.md>
"Currently, the only supported LTS branch is: mbedtls-2.28.
For a short time we also have the previous LTS, which has
recently ended its support period, mbedtls-2.16.
This branch will move into the archive namespace around the
time of the next release."
this will also add support for uacme ualpn support.

This fixes the following security problems:
* Zeroize several intermediate variables used to calculate the expected
value when verifying a MAC or AEAD tag. This hardens the library in
case the value leaks through a memory disclosure vulnerability. For
example, a memory disclosure vulnerability could have allowed a
man-in-the-middle to inject fake ciphertext into a DTLS connection.
* Fix a double-free that happened after mbedtls_ssl_set_session() or
mbedtls_ssl_get_session() failed with MBEDTLS_ERR_SSL_ALLOC_FAILED
(out of memory). After that, calling mbedtls_ssl_session_free()
and mbedtls_ssl_free() would cause an internal session buffer to
be free()'d twice. CVE-2021-44732

session tickets are a feature of TLSv1.2 and require less memory
and overhead on the server than does managing a session cache
Building mbedtls with support for session tickets will allow the
feature to be used with lighttpd-1.4.56 and later.

A compact patch that provides AES and GCM implementations that utilize the
ARMv8 Crypto Extensions. The config flag is MBEDTLS_ARMV8CE_AES_C, which
is disabled by default as we don't do runtime checking for the feature.
The new implementation lives in armv8ce_aes.c.
Provides similar functionality to https://github.com/ARMmbed/mbedtls/pull/432
Thanks to Barry O'Rourke and others for that contribtion.
Tested on a Cortex A53 device and QEMU. On a midrange phone the real AES-GCM
throughput increases about 4x, while raw AES speed is up to 10x faster.
[updated Makefile to enable this function, adjusted commit message]

This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for security issues and the most notable of them
are described in more detail in the security advisories.
* Local side channel attack on RSA and static Diffie-Hellman
* Local side channel attack on classical CBC decryption in (D)TLS
* When checking X.509 CRLs, a certificate was only considered as revoked
if its revocationDate was in the past according to the local clock if
available.

Mbed TLS 2.16.7 is a maintenance release of the Mbed TLS 2.16 branch,
and provides bug fixes and minor enhancements. This release includes
fixes for security issues and the most severe one is described in more
detail in a security advisory:
https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2020-07
* Fix a side channel vulnerability in modular exponentiation that could
reveal an RSA private key used in a secure enclave.
* Fix side channel in mbedtls_ecp_check_pub_priv() and
mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a private
key that didn't include the uncompressed public key), as well as
mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL
f_rng argument. An attacker with access to precise enough timing and
memory access information (typically an untrusted operating system
attacking a secure enclave) could fully recover the ECC private key.
* Fix issue in Lucky 13 counter-measure that could make it ineffective when
hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT
macros).
Due to Mbed TLS moving from ARMmbed to the Trusted Firmware project, some
changes to the download URLs are required. For the time being, the
ARMmbed/mbedtls Github repository is the canonical source for Mbed TLS.

This introduces a new Kconfig option to switch on/off mbedtls' support
for debug functions.
The idea behind is to inspect TLS traffic with Wireshark for debug
purposes. At the moment, there is no native or 'nice' support for
this, but at
68aea15833
an example implementation can be found which uses the debug functions
of the library. However, this requires to have this debug stuff enabled
in the library, but at the moment it is staticly patched out.
So this patch removes the static part from the configuration patch
and introduces a dynamic config file editing during build.
When enabled, this heavily increases the library size, so I added
a warning in the Kconfig help section.

In the case of upstream libraries, set the ABI_VERSION variable to the
soname value of the first version version after the last backwards
incompatible change.
For custom OpenWrt libraries, set the ABI_VERSION to the date of the
last Git commit doing backwards incompatible changes to the source,
such as changing function singatures or dropping exported symbols.
The soname values have been determined by either checking
https://abi-laboratory.pro/index.php?view=tracker or - in the case
of OpenWrt libraries - by carefully reviewing the changes made to
header files thorough the corresponding Git history.
In the future, the ABI_VERSION values must be bumped whenever the
library is updated to an incpompatible version but not with every
package update, in order to reduce the dependency churn in the
binary package repository.

With deterministic ECDSA the value k needed for the ECDSA signature is
not randomly generated any more, but generated from a hash over the
private key and the message to sign. If the value k used in a ECDSA
signature or the relationship between the two values k used in two
different ECDSA signatures over the same content is know to an attacker
he can derive the private key pretty easily. Using deterministic ECDSA
as defined in the RFC6979 removes this problem by deriving the value k
deterministically from the private key and the content which gets
signed.
The resulting signature is still compatible to signatures generated not
deterministic.
This increases the size of the ipk on mips 24Kc by about 2 KByte.

Disable MBEDTLS_SHA256_SMALLER implementation, not enabled by default in
upstream and reduces performance by quite a bit.
Source: include/mbedtls/config.h
Enable an implementation of SHA-256 that has lower ROM footprint but also
lower performance.
The default implementation is meant to be a reasonnable compromise between
performance and size. This version optimizes more aggressively for size at
the expense of performance. Eg on Cortex-M4 it reduces the size of
mbedtls_sha256_process() from ~2KB to ~0.5KB for a performance hit of
about 30%.
The size of mbedtls increased a little bit:
ipkg for mips_24kc before:
164.382 Bytes
ipkg for mips_24kc after:
166.240 Bytes
