 Mbed TLS ChangeLog (Sorted per branch, date)
 
+= Mbed TLS 3.4.0 branch released 2023-03-28
+
+Default behavior changes
+   * The default priority order of TLS 1.3 cipher suites has been modified to
+     follow the same rules as the TLS 1.2 cipher suites (see
+     ssl_ciphersuites.c). The preferred cipher suite is now
+     TLS_CHACHA20_POLY1305_SHA256.
+
+New deprecations
+   * mbedtls_x509write_crt_set_serial() is now being deprecated in favor of
+     mbedtls_x509write_crt_set_serial_raw(). The goal here is to remove any
+     direct dependency of X509 on BIGNUM_C.
+   * PSA to mbedtls error translation is now unified in psa_util.h,
+     deprecating mbedtls_md_error_from_psa. Each file that performs error
+     translation should define its own version of PSA_TO_MBEDTLS_ERR,
+     optionally providing file-specific error pairs. Please see psa_util.h for
+     more details.
+
+Features
+   * Added partial support for parsing the PKCS #7 Cryptographic Message
+     Syntax, as defined in RFC 2315. Currently, support is limited to the
+     following:
+     - Only the signed-data content type, version 1 is supported.
+     - Only DER encoding is supported.
+     - Only a single digest algorithm per message is supported.
+     - Certificates must be in X.509 format. A message must have either 0
+       or 1 certificates.
+     - There is no support for certificate revocation lists.
+     - The authenticated and unauthenticated attribute fields of SignerInfo
+       must be empty.
+     Many thanks to Daniel Axtens, Nayna Jain, and Nick Child from IBM for
+     contributing this feature, and to Demi-Marie Obenour for contributing
+     various improvements, tests and bug fixes.
+   * General performance improvements by accessing multiple bytes at a time.
+     Fixes #1666.
+   * Improvements to use of unaligned and byte-swapped memory, reducing code
+     size and improving performance (depending on compiler and target
+     architecture).
+   * Add support for reading points in compressed format
+     (MBEDTLS_ECP_PF_COMPRESSED) with mbedtls_ecp_point_read_binary()
+     (and callers) for Short Weierstrass curves with prime p where p = 3 mod 4
+     (all mbedtls MBEDTLS_ECP_DP_SECP* and MBEDTLS_ECP_DP_BP* curves
+      except MBEDTLS_ECP_DP_SECP224R1 and MBEDTLS_ECP_DP_SECP224K1)
+   * SHA224_C/SHA384_C are now independent from SHA384_C/SHA512_C respectively.
+     This helps in saving code size when some of the above hashes are not
+     required.
+   * Add parsing of V3 extensions (key usage, Netscape cert-type,
+     Subject Alternative Names) in x509 Certificate Sign Requests.
+   * Use HOSTCC (if it is set) when compiling C code during generation of the
+     configuration-independent files. This allows them to be generated when
+     CC is set for cross compilation.
+   * Add parsing of uniformResourceIdentifier subtype for subjectAltName
+     extension in x509 certificates.
+   * Add an interruptible version of sign and verify hash to the PSA interface,
+     backed by internal library support for ECDSA signing and verification.
+   * Add parsing of rfc822Name subtype for subjectAltName
+     extension in x509 certificates.
+   * The configuration macros MBEDTLS_PSA_CRYPTO_PLATFORM_FILE and
+     MBEDTLS_PSA_CRYPTO_STRUCT_FILE specify alternative locations for
+     the headers "psa/crypto_platform.h" and "psa/crypto_struct.h".
+   * When a PSA driver for ECDSA is present, it is now possible to disable
+     MBEDTLS_ECDSA_C in the build in order to save code size. For PK, X.509
+     and TLS to fully work, this requires MBEDTLS_USE_PSA_CRYPTO to be enabled.
+     Restartable/interruptible ECDSA operations in PK, X.509 and TLS are not
+     supported in those builds yet, as driver support for interruptible ECDSA
+     operations is not present yet.
+   * Add a driver dispatch layer for EC J-PAKE, enabling alternative
+     implementations of EC J-PAKE through the driver entry points.
+   * Add new API mbedtls_ssl_cache_remove for cache entry removal by
+     its session id.
+   * Add support to include the SubjectAltName extension to a CSR.
+   * Add support for AES with the Armv8-A Cryptographic Extension on
+     64-bit Arm. A new configuration option, MBEDTLS_AESCE_C, can
+     be used to enable this feature. Run-time detection is supported
+     under Linux only.
+   * When a PSA driver for EC J-PAKE is present, it is now possible to disable
+     MBEDTLS_ECJPAKE_C in the build in order to save code size. For the
+     corresponding TLS 1.2 key exchange to work, MBEDTLS_USE_PSA_CRYPTO needs
+     to be enabled.
+   * Add functions mbedtls_rsa_get_padding_mode() and mbedtls_rsa_get_md_alg()
+     to read non-public fields for padding mode and hash id from
+     an mbedtls_rsa_context, as requested in #6917.
+   * AES-NI is now supported with Visual Studio.
+   * AES-NI is now supported in 32-bit builds, or when MBEDTLS_HAVE_ASM
+     is disabled, when compiling with GCC or Clang or a compatible compiler
+     for a target CPU that supports the requisite instructions (for example
+     gcc -m32 -msse2 -maes -mpclmul). (Generic x86 builds with GCC-like
+     compilers still require MBEDTLS_HAVE_ASM and a 64-bit target.)
+   * It is now possible to use a PSA-held (opaque) password with the TLS 1.2
+     ECJPAKE key exchange, using the new API function
+     mbedtls_ssl_set_hs_ecjpake_password_opaque().
+
+Security
+   * Use platform-provided secure zeroization function where possible, such as
+     explicit_bzero().
+   * Zeroize SSL cache entries when they are freed.
+   * Fix a potential heap buffer overread in TLS 1.3 client-side when
+     MBEDTLS_DEBUG_C is enabled. This may result in an application crash.
+   * Add support for AES with the Armv8-A Cryptographic Extension on 64-bit
+     Arm, so that these systems are no longer vulnerable to timing side-channel
+     attacks. This is configured by MBEDTLS_AESCE_C, which is on by default.
+     Reported by Demi Marie Obenour.
+   * MBEDTLS_AESNI_C, which is enabled by default, was silently ignored on
+     builds that couldn't compile the GCC-style assembly implementation
+     (most notably builds with Visual Studio), leaving them vulnerable to
+     timing side-channel attacks. There is now an intrinsics-based AES-NI
+     implementation as a fallback for when the assembly one cannot be used.
+
+Bugfix
+   * Fix possible integer overflow in mbedtls_timing_hardclock(), which
+     could cause a crash in programs/test/benchmark.
+   * Fix IAR compiler warnings. Fixes #6924.
+   * Fix a bug in the build where directory names containing spaces were
+     causing generate_errors.pl to error out resulting in a build failure.
+     Fixes issue #6879.
+   * In TLS 1.3, when using a ticket for session resumption, tweak its age
+     calculation on the client side. It prevents a server with more accurate
+     ticket timestamps (typically timestamps in milliseconds) compared to the
+     Mbed TLS ticket timestamps (in seconds) to compute a ticket age smaller
+     than the age computed and transmitted by the client and thus potentially
+     reject the ticket. Fix #6623.
+   * Fix compile error where MBEDTLS_RSA_C and MBEDTLS_X509_CRT_WRITE_C are
+     defined, but MBEDTLS_PK_RSA_ALT_SUPPORT is not defined. Fixes #3174.
+   * List PSA_WANT_ALG_CCM_STAR_NO_TAG in psa/crypto_config.h so that it can
+     be toggled with config.py.
+   * The key derivation algorithm PSA_ALG_TLS12_ECJPAKE_TO_PMS cannot be
+     used on a shared secret from a key agreement since its input must be
+     an ECC public key. Reject this properly.
+   * mbedtls_x509write_crt_set_serial() now explicitly rejects serial numbers
+     whose binary representation is longer than 20 bytes. This was already
+     forbidden by the standard (RFC5280 - section 4.1.2.2) and now it's being
+     enforced also at code level.
+   * Fix potential undefined behavior in mbedtls_mpi_sub_abs().  Reported by
+     Pascal Cuoq using TrustInSoft Analyzer in #6701; observed independently by
+     Aaron Ucko under Valgrind.
+   * Fix behavior of certain sample programs which could, when run with no
+     arguments, access uninitialized memory in some cases. Fixes #6700 (which
+     was found by TrustInSoft Analyzer during REDOCS'22) and #1120.
+   * Fix parsing of X.509 SubjectAlternativeName extension. Previously,
+     malformed alternative name components were not caught during initial
+     certificate parsing, but only on subsequent calls to
+     mbedtls_x509_parse_subject_alt_name(). Fixes #2838.
+   * Make the fields of mbedtls_pk_rsassa_pss_options public. This makes it
+     possible to verify RSA PSS signatures with the pk module, which was
+     inadvertently broken since Mbed TLS 3.0.
+   * Fix bug in conversion from OID to string in
+     mbedtls_oid_get_numeric_string(). OIDs such as 2.40.0.25 are now printed
+     correctly.
+   * Reject OIDs with overlong-encoded subidentifiers when converting
+     them to a string.
+   * Reject OIDs with subidentifier values exceeding UINT_MAX.  Such
+     subidentifiers can be valid, but Mbed TLS cannot currently handle them.
+   * Reject OIDs that have unterminated subidentifiers, or (equivalently)
+     have the most-significant bit set in their last byte.
+   * Silence warnings from clang -Wdocumentation about empty \retval
+     descriptions, which started appearing with Clang 15. Fixes #6960.
+   * Fix the handling of renegotiation attempts in TLS 1.3. They are now
+     systematically rejected.
+   * Fix an unused-variable warning in TLS 1.3-only builds if
+     MBEDTLS_SSL_RENEGOTIATION was enabled. Fixes #6200.
+   * Fix undefined behavior in mbedtls_ssl_read() and mbedtls_ssl_write() if
+     len argument is 0 and buffer is NULL.
+   * Allow setting user and peer identifiers for EC J-PAKE operation
+     instead of role in PAKE PSA Crypto API as described in the specification.
+     This is a partial fix that allows only "client" and "server" identifiers.
+   * Fix a compilation error when PSA Crypto is built with support for
+     TLS12_PRF but not TLS12_PSK_TO_MS. Reported by joerchan in #7125.
+   * In the TLS 1.3 server, select the preferred client cipher suite, not the
+     least preferred. The selection error was introduced in Mbed TLS 3.3.0.
+   * Fix TLS 1.3 session resumption when the established pre-shared key is
+     384 bits long. That is the length of pre-shared keys created under a
+     session where the cipher suite is TLS_AES_256_GCM_SHA384.
+   * Fix an issue when compiling with MBEDTLS_SHA512_USE_A64_CRYPTO_IF_PRESENT
+     enabled, which required specifying compiler flags enabling SHA3 Crypto
+     Extensions, where some compilers would emit EOR3 instructions in other
+     modules, which would then fail if run on a CPU without the SHA3
+     extensions. Fixes #5758.
+
+Changes
+   * Install the .cmake files into CMAKE_INSTALL_LIBDIR/cmake/MbedTLS,
+     typically /usr/lib/cmake/MbedTLS.
+   * Mixed-endian systems are explicitly not supported any more.
+   * When MBEDTLS_USE_PSA_CRYPTO and MBEDTLS_ECDSA_DETERMINISTIC are both
+     defined, mbedtls_pk_sign() now use deterministic ECDSA for ECDSA
+     signatures. This aligns the behaviour with MBEDTLS_USE_PSA_CRYPTO to
+     the behaviour without it, where deterministic ECDSA was already used.
+   * Visual Studio: Rename the directory containing Visual Studio files from
+     visualc/VS2010 to visualc/VS2013 as we do not support building with versions
+     older than 2013. Update the solution file to specify VS2013 as a minimum.
+   * programs/x509/cert_write:
+     - now it accepts the serial number in 2 different formats: decimal and
+       hex. They cannot be used simultaneously
+     - "serial" is used for the decimal format and it's limted in size to
+       unsigned long long int
+     - "serial_hex" is used for the hex format; max length here is
+       MBEDTLS_X509_RFC5280_MAX_SERIAL_LEN*2
+   * The C code follows a new coding style. This is transparent for users but
+     affects contributors and maintainers of local patches. For more
+     information, see
+     https://mbed-tls.readthedocs.io/en/latest/kb/how-to/rewrite-branch-for-coding-style/
+   * Changed the default MBEDTLS_ECP_WINDOW_SIZE from 6 to 2.
+     As tested in issue 6790, the correlation between this define and
+     RSA decryption performance has changed lately due to security fixes.
+     To fix the performance degradation when using default values the
+     window was reduced from 6 to 2, a value that gives the best or close
+     to best results when tested on Cortex-M4 and Intel i7.
+   * When enabling MBEDTLS_SHA256_USE_A64_CRYPTO_* or
+     MBEDTLS_SHA512_USE_A64_CRYPTO_*, it is no longer necessary to specify
+     compiler target flags on the command line; the library now sets target
+     options within the appropriate modules.

+
+## Threat model
+
+We classify attacks based on the capabilities of the attacker.
+
+### Remote attacks
+
+In this section, we consider an attacker who can observe and modify data sent
+over the network. This includes observing the content and timing of individual
+packets, as well as suppressing or delaying legitimate messages, and injecting
+messages.
+
+Mbed TLS aims to fully protect against remote attacks and to enable the user
+application in providing full protection against remote attacks. Said
+protection is limited to providing security guarantees offered by the protocol
+being implemented. (For example Mbed TLS alone won't guarantee that the
+messages will arrive without delay, as the TLS protocol doesn't guarantee that
+either.)
+
+**Warning!** Block ciphers do not yet achieve full protection against attackers
+who can measure the timing of packets with sufficient precision. For details
+and workarounds see the [Block Ciphers](#block-ciphers) section.
+
+### Local attacks
+
+In this section, we consider an attacker who can run software on the same
+machine. The attacker has insufficient privileges to directly access Mbed TLS
+assets such as memory and files.
+
+#### Timing attacks
+
+The attacker is able to observe the timing of instructions executed by Mbed TLS
+by leveraging shared hardware that both Mbed TLS and the attacker have access
+to. Typical attack vectors include cache timings, memory bus contention and
+branch prediction.
+
+Mbed TLS provides limited protection against timing attacks. The cost of
+protecting against timing attacks widely varies depending on the granularity of
+the measurements and the noise present. Therefore the protection in Mbed TLS is
+limited. We are only aiming to provide protection against **publicly
+documented attack techniques**.
+
+As attacks keep improving, so does Mbed TLS's protection. Mbed TLS is moving
+towards a model of fully timing-invariant code, but has not reached this point
+yet.
+
+**Remark:** Timing information can be observed over the network or through
+physical side channels as well. Remote and physical timing attacks are covered
+in the [Remote attacks](remote-attacks) and [Physical
+attacks](physical-attacks) sections respectively.
+
+**Warning!** Block ciphers do not yet achieve full protection. For
+details and workarounds see the [Block Ciphers](#block-ciphers) section.
+
+#### Local non-timing side channels
+
+The attacker code running on the platform has access to some sensor capable of
+picking up information on the physical state of the hardware while Mbed TLS is
+running. This could for example be an analogue-to-digital converter on the
+platform that is located unfortunately enough to pick up the CPU noise.
+
+Mbed TLS doesn't make any security guarantees against local non-timing-based
+side channel attacks. If local non-timing attacks are present in a use case or
+a user application's threat model, they need to be mitigated by the platform.
+
+#### Local fault injection attacks
+
+Software running on the same hardware can affect the physical state of the
+device and introduce faults.
+
+Mbed TLS doesn't make any security guarantees against local fault injection
+attacks. If local fault injection attacks are present in a use case or a user
+application's threat model, they need to be mitigated by the platform.
+
+### Physical attacks
+
+In this section, we consider an attacker who has access to physical information
+about the hardware Mbed TLS is running on and/or can alter the physical state
+of the hardware (e.g. power analysis, radio emissions or fault injection).
+
+Mbed TLS doesn't make any security guarantees against physical attacks. If
+physical attacks are present in a use case or a user application's threat
+model, they need to be mitigated by physical countermeasures.
+
+### Caveats
+
+#### Out-of-scope countermeasures
+
+Mbed TLS has evolved organically and a well defined threat model hasn't always
+been present. Therefore, Mbed TLS might have countermeasures against attacks
+outside the above defined threat model.
+
+The presence of such countermeasures don't mean that Mbed TLS provides
+protection against a class of attacks outside of the above described threat
+model. Neither does it mean that the failure of such a countermeasure is
+considered a vulnerability.
+
+#### Block ciphers
+
+Currently there are four block ciphers in Mbed TLS: AES, CAMELLIA, ARIA and
+DES. The pure software implementation in Mbed TLS implementation uses lookup
+tables, which are vulnerable to timing attacks.
+
+These timing attacks can be physical, local or depending on network latency
+even a remote. The attacks can result in key recovery.
+
+**Workarounds:**
+
+- Turn on hardware acceleration for AES. This is supported only on selected
+  architectures and currently only available for AES. See configuration options
+  `MBEDTLS_AESCE_C`, `MBEDTLS_AESNI_C` and `MBEDTLS_PADLOCK_C` for details.
+- Add a secure alternative implementation (typically hardware acceleration) for
+  the vulnerable cipher. See the [Alternative Implementations
+Guide](docs/architecture/alternative-implementations.md) for more information.
+- Use cryptographic mechanisms that are not based on block ciphers. In
+  particular, for authenticated encryption, use ChaCha20/Poly1305 instead of
+  block cipher modes. For random generation, use HMAC\_DRBG instead of CTR\_DRBG.

-Regarding libmbedcrypto, outside of the RNG subsystem, for modules that
-currently depend on other legacy crypto modules, this can be achieved without
-backwards compatibility issues, by using the software implementation if
-available, and "falling back" to PSA only if it's not. The compile-time
-dependency changes from the current one (say, `MD_C` or `AES_C`) to "the
-previous dependency OR PSA Crypto with needed algorithms". When building
-without software implementation, users need to call `psa_crypto_init()` before
-calling any function from these modules. This condition does not constitute a
-break of backwards compatibility, as it was previously impossible to build in
-those configurations, and in configurations were the build was possible,
-application code keeps working unchanged. An work-in-progress example of
-applying this strategy, for RSA PKCS#1 v2.1, is here:
-<https://github.com/Mbed-TLS/mbedtls/pull/6141>
-
-There is a problem with the modules used for the PSA RNG, as currently the RNG
-is initialized before drivers and the key store. This part will need further
-study, but in the meantime we can proceed with everything that's not the
-entropy module of one of the DRBG modules, and that does not depend on one of

-the ability to "fall back" to using PSA if the legacy dependency isn't
-available. Data related to a certain hash (OID, sizes, translations) should
-only be included in the build if it is possible to use that hash in some way.
+As much as possible, we're trying to create for each algorithm a single new

+code that should always use `PSA_WANT`). For example, for hashes this is the
+`MBEDTLS_MD_CAN_xxx` family. For ECC algorithms, we have similar
+`MBEDTLS_PK_CAN_xxx` macros.
 
-In order to cater to these new needs, new families of macros are introduced in
-`legacy_or_psa.h`, see its documentation for details.
-
-It should be noted that there are currently:
-- too many different ways of computing a hash (low-level, MD, PSA);
-- too many different ways to configure the library that influence which of
-  these ways is available and will be used (`MBEDTLS_USE_PSA_CRYPTO`,
-  `MBEDTLS_PSA_CRYPTO_CONFIG`, `mbedtls_config.h` + `psa/crypto_config.h`).

-As a result, we need more families of dependency macros than we'd like to.
-This is a temporary situation until we move to a place where everything is
-based on PSA Crypto. In the meantime, long and explicit names where chosen for
-the new macros in the hope of avoiding confusion.
-
-Note: the new macros supplement but do not replace the existing macros:
-- code that always uses PSA Crypto (for example, code specific to TLS 1.3)
-  should use `PSA_WANT_xxx`;
-- code that always uses the legacy API (for example, crypto modules that have
-  not undergone step 1 yet) should use `MBEDTLS_xxx_C`;
-- code that may use one of the two APIs, either based on
-  `MBEDTLS_USE_PSA_CRYPTO` (X.509, TLS 1.2, shared between TLS 1.2 and 1.3),
-  or based on availability (crypto modules after step 1), should use one of
-  the new macros from `legacy_or_psa.h`.
+Note that in order to achieve that goal, even for code that obeys
+`USE_PSA_CRYPTO`, it is useful to impose that all algorithms that are
+available via the legacy APIs are also available via PSA.
 
 Executing step 3 will mostly consist of using the right dependency macros in
 the right places (once the previous steps are done).
