<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.

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.

This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for security issues.
Security fixes:
* Fix a buffer overflow in mbedtls_mpi_sub_abs()
* Fix an errorneous estimation for an internal buffer in
mbedtls_pk_write_key_pem()
* Fix a stack buffer overflow with mbedtls_net_poll() and
mbedtls_net_recv_timeout()
* Guard against strong local side channel attack against base64 tables
by making access aceess to them use constant flow code

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.

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%.

Fixed an authentication bypass issue in SSL/TLS. When the TLS
authentication mode was set to 'optional',
mbedtls_ssl_get_verify_result() would incorrectly return 0 when the
peer's X.509 certificate chain had more than
MBEDTLS_X509_MAX_INTERMEDIATE_CA intermediates (default: 8), even when
it was not trusted. This could be triggered remotely on both the client
and server side. (Note, with the authentication mode set by
mbedtls_ssl_conf_authmode()to be 'required' (the default), the handshake
was correctly aborted).
