This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for following security issues:
* Timing side channel in private key RSA operations (CVE-2024-23170)
Mbed TLS is vulnerable to a timing side channel in private key RSA
operations. This side channel could be sufficient for an attacker to
recover the plaintext. A local attacker or a remote attacker who is
close to the victim on the network might have precise enough timing
measurements to exploit this. It requires the attacker to send a large
number of messages for decryption.
* Buffer overflow in mbedtls_x509_set_extension() (CVE-2024-23775)
When writing x509 extensions we failed to validate inputs passed in to
mbedtls_x509_set_extension(), which could result in an integer overflow,
causing a zero-length buffer to be allocated to hold the extension. The
extension would then be copied into the buffer, causing a heap buffer
overflow.
Fixes: CVE-2024-23170, CVE-2024-23775

This reduces open coding and allows to easily add a knob to
enable it treewide, where chosen packages can still opt-out via
"no-gc-sections".
Note: libnl, mbedtls and opkg only used the CFLAGS part without the
LDFLAGS counterpart. That doesn't help at all if the goal is to produce
smaller binaries. I consider that an accident, and this fixes it.
Note: there are also packages using only the LDFLAGS part. I didn't
touch those, as gc might have been disabled via CFLAGS intentionally.

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

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.
