mbed TLS ChangeLog (Sorted per branch, date)
= mbed TLS 2.14.0 branch released 2018-11-19
Security
* Fix overly strict DN comparison when looking for CRLs belonging to a
particular CA. This previously led to ignoring CRLs when the CRL's issuer
name and the CA's subject name differed in their string encoding (e.g.,
one using PrintableString and the other UTF8String) or in the choice of
upper and lower case. Reported by Henrik Andersson of Bosch GmbH in issue
#1784.
* Fix a flawed bounds check in server PSK hint parsing. In case the
incoming message buffer was placed within the first 64KiB of address
space and a PSK-(EC)DHE ciphersuite was used, this allowed an attacker
to trigger a memory access up to 64KiB beyond the incoming message buffer,
potentially leading to an application crash or information disclosure.
* Fix mbedtls_mpi_is_prime() to use more rounds of probabilistic testing. The
previous settings for the number of rounds made it practical for an
adversary to construct non-primes that would be erroneously accepted as
primes with high probability. This does not have an impact on the
security of TLS, but can matter in other contexts with numbers chosen
potentially by an adversary that should be prime and can be validated.
For example, the number of rounds was enough to securely generate RSA key
pairs or Diffie-Hellman parameters, but was insufficient to validate
Diffie-Hellman parameters properly.
See "Prime and Prejudice" by by Martin R. Albrecht and Jake Massimo and
Kenneth G. Paterson and Juraj Somorovsky.
Features
* Add support for temporarily suspending expensive ECC computations after
some configurable amount of operations. This is intended to be used in
constrained, single-threaded systems where ECC is time consuming and can
block other operations until they complete. This is disabled by default,
but can be enabled by MBEDTLS_ECP_RESTARTABLE at compile time and
configured by mbedtls_ecp_set_max_ops() at runtime. It applies to the new
xxx_restartable functions in ECP, ECDSA, PK and X.509 (CRL not supported
yet), and to existing functions in ECDH and SSL (currently only
implemented client-side, for ECDHE-ECDSA ciphersuites in TLS 1.2,
including client authentication).
* Add support for Arm CPU DSP extensions to accelerate asymmetric key
operations. On CPUs where the extensions are available, they can accelerate
MPI multiplications used in ECC and RSA cryptography. Contributed by
Aurelien Jarno.
* Extend RSASSA-PSS signature to allow a smaller salt size. Previously, PSS
signature always used a salt with the same length as the hash, and returned
an error if this was not possible. Now the salt size may be up to two bytes
shorter. This allows the library to support all hash and signature sizes
that comply with FIPS 186-4, including SHA-512 with a 1024-bit key.
* Add support for 128-bit keys in CTR_DRBG. Note that using keys shorter
than 256 bits limits the security of generated material to 128 bits.
API Changes
* Add a common error code of `MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED` for
a feature that is not supported by underlying alternative
implementations implementing cryptographic primitives. This is useful for
hardware accelerators that don't implement all options or features.
New deprecations
* All module specific errors following the form
MBEDTLS_ERR_XXX_FEATURE_UNAVAILABLE that indicate a feature is not
supported are deprecated and are now replaced by the new equivalent
platform error.
* All module specific generic hardware acceleration errors following the
form MBEDTLS_ERR_XXX_HW_ACCEL_FAILED that are deprecated and are replaced
by the equivalent plaform error.
* Deprecate the function mbedtls_mpi_is_prime() in favor of
mbedtls_mpi_is_prime_ext() which allows specifying the number of
Miller-Rabin rounds.
Bugfix
* Fix wrong order of freeing in programs/ssl/ssl_server2 example
application leading to a memory leak in case both
MBEDTLS_MEMORY_BUFFER_ALLOC_C and MBEDTLS_MEMORY_BACKTRACE are set.
Fixes #2069.
* Fix a bug in the update function for SSL ticket keys which previously
invalidated keys of a lifetime of less than a 1s. Fixes #1968.
* Fix failure in hmac_drbg in the benchmark sample application, when
MBEDTLS_THREADING_C is defined. Found by TrinityTonic, #1095
* Fix a bug in the record decryption routine ssl_decrypt_buf()
which lead to accepting properly authenticated but improperly
padded records in case of CBC ciphersuites using Encrypt-then-MAC.
* Fix memory leak and freeing without initialization in the example
program programs/x509/cert_write. Fixes #1422.
* Ignore IV in mbedtls_cipher_set_iv() when the cipher mode is
MBEDTLS_MODE_ECB. Found by ezdevelop. Fixes #1091.
* Zeroize memory used for buffering or reassembling handshake messages
after use.
* Use `mbedtls_platform_zeroize()` instead of `memset()` for zeroization
of sensitive data in the example programs aescrypt2 and crypt_and_hash.
* Change the default string format used for various X.509 DN attributes to
UTF8String. Previously, the use of the PrintableString format led to
wildcards and non-ASCII characters being unusable in some DN attributes.
Reported by raprepo in #1860 and by kevinpt in #468. Fix contributed by
Thomas-Dee.
* Fix compilation failure for configurations which use compile time
replacements of standard calloc/free functions through the macros
MBEDTLS_PLATFORM_CALLOC_MACRO and MBEDTLS_PLATFORM_FREE_MACRO.
Reported by ole-de and ddhome2006. Fixes #882, #1642 and #1706.
Changes
* Removed support for Yotta as a build tool.
* Add tests for session resumption in DTLS.
* Close a test gap in (D)TLS between the client side and the server side:
test the handling of large packets and small packets on the client side
in the same way as on the server side.
* Change the dtls_client and dtls_server samples to work by default over
IPv6 and optionally by a build option over IPv4.
* Change the use of Windows threading to use Microsoft Visual C++ runtime
calls, rather than Win32 API calls directly. This is necessary to avoid
conflict with C runtime usage. Found and fixed by irwir.
* Remember the string format of X.509 DN attributes when replicating
X.509 DNs. Previously, DN attributes were always written in their default
string format (mostly PrintableString), which could lead to CRTs being
created which used PrintableStrings in the issuer field even though the
signing CA used UTF8Strings in its subject field; while X.509 compliant,
such CRTs were rejected in some applications, e.g. some versions of
Firefox, curl and GnuTLS. Reported in #1033 by Moschn. Fix contributed by
Thomas-Dee.
* Improve documentation of mbedtls_ssl_get_verify_result().
Fixes #517 reported by github-monoculture.
* Add MBEDTLS_MPI_GEN_PRIME_FLAG_LOW_ERR flag to mbedtls_mpi_gen_prime() and
use it to reduce error probability in RSA key generation to levels mandated
by FIPS-186-4.
= mbed TLS 2.13.1 branch released 2018-09-06
API Changes
* Extend the platform module with an abstraction mbedtls_platform_gmtime_r()
whose implementation should behave as a thread-safe version of gmtime().
This allows users to configure such an implementation at compile time when
the target system cannot be deduced automatically, by setting the option
MBEDTLS_PLATFORM_GMTIME_R_ALT. At this stage Mbed TLS is only able to
automatically select implementations for Windows and POSIX C libraries.
Bugfix
* Fix build failures on platforms where only gmtime() is available but
neither gmtime_r() nor gmtime_s() are present. Fixes #1907.

There are currently four active build systems used within Mbed TLS releases:
There are currently three active build systems used within Mbed TLS releases:
- yotta
- GNU Make
- CMake
- Microsoft Visual Studio (Microsoft Visual Studio 2010 or later)
The main systems used for development are CMake and GNU Make. Those systems are always complete and up-to-date. The others should reflect all changes present in the CMake and Make build system, although features may not be ported there automatically.
Yotta, as a build system, is slightly different from the other build systems:
- it provides a minimalistic configuration file by default
- depending on the yotta target, features of Mbed OS may be used in examples and tests
The Make and CMake build systems create three libraries: libmbedcrypto, libmbedx509, and libmbedtls. Note that libmbedtls depends on libmbedx509 and libmbedcrypto, and libmbedx509 depends on libmbedcrypto. As a result, some linkers will expect flags to be in a specific order, for example the GNU linker wants `-lmbedtls -lmbedx509 -lmbedcrypto`. Also, when loading shared libraries using dlopen(), you'll need to load libmbedcrypto first, then libmbedx509, before you can load libmbedtls.
### Yotta
[yotta](http://yottabuild.org) is a package manager and build system developed by Mbed, and is the build system of Mbed OS 16.03. To install it on your platform, please follow the yotta [installation instructions](http://docs.yottabuild.org/#installing).
Once yotta is installed, you can use it to download the latest version of Mbed TLS from the yotta registry with:
yotta install mbedtls
and build it with:
yotta build
If, on the other hand, you already have a copy of Mbed TLS from a source other than the yotta registry, for example from cloning our GitHub repository, or from downloading a tarball of the standalone edition, then you'll first need to generate the yotta module by running:
yotta/create-module.sh
This should be executed from the root Mbed TLS project directory. This will create the yotta module in the `yotta/module` directory within it. You can then change to that directory and build as usual:
cd yotta/module
yotta build
In any case, you'll probably want to set the yotta target before building unless it has already been set globally. For more information on using yotta, please consult the [yotta documentation](http://docs.yottabuild.org/).
For more details on the yotta/Mbed OS edition of Mbed TLS, including example programs, please consult the [Readme at the root of the yotta module](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/README.md).
### Make
We require GNU Make. To build the library and the sample programs, GNU Make and a C compiler are sufficient. Some of the more advanced build targets require some Unix/Linux tools.

Setting the variable `SHARED` in your environment will build shared libraries in addition to the static libraries. Setting `DEBUG` gives you a debug build. You can override `CFLAGS` and `LDFLAGS` by setting them in your environment or on the make command line; compiler warning options may be overridden separately using `WARNING_CFLAGS`. Some directory-specific options (for example, `-I` directives) are still preserved.
Please note that setting `CFLAGS` overrides its default value of `-O2` and setting `WARNING_CFLAGS` overrides its default value (starting with `-Wall -W`), so it you just want to add some warning options to the default ones, you can do so by setting `CFLAGS=-O2 -Werror` for example. Setting `WARNING_CFLAGS` is useful when you want to get rid of its default content (for example because your compiler doesn't accept `-Wall` as an option). Directory-specific options cannot be overriden from the command line.

Depending on your platform, you might run into some issues. Please check the Makefiles in `library/`, `programs/` and `tests/` for options to manually add or remove for specific platforms. You can also check [the Mbed TLS Knowledge Base](https://tls.mbed.org/kb) for articles on your platform or issue.

* If more operations are needed to complete a computation,

* caller's responsibility to either call again with the same
* parameters until it returns 0 or an error code; or to free
* the restart context if the operation is to be aborted.
*
* It is strictly required that all input parameters and the
* restart context be the same on successive calls for the
* same operation, but output parameters need not be the
* same; they must not be used until the function finally
* returns 0.
*
* This only applies to functions whose documentation
* mentions they may return #MBEDTLS_ERR_ECP_IN_PROGRESS (or
* #MBEDTLS_ERR_SSL_CRYPTO_IN_PROGRESS for functions in the
* SSL module). For functions that accept a "restart context"
* argument, passing NULL disables restart and makes the
* function equivalent to the function with the same name
* with \c _restartable removed. For functions in the ECDH
* module, restart is disabled unless the function accepts
* an "ECDH context" argument and
* mbedtls_ecdh_enable_restart() was previously called on
* that context. For function in the SSL module, restart is
* only enabled for specific sides and key exchanges
* (currently only for clients and ECDHE-ECDSA).
*
* \param max_ops Maximum number of basic operations done in a row.
* Default: 0 (unlimited).
* Lower (non-zero) values mean ECC functions will block for
* a lesser maximum amount of time.
*
* \note A "basic operation" is defined as a rough equivalent of a
* multiplication in GF(p) for the NIST P-256 curve.
* As an indication, with default settings, a scalar
* multiplication (full run of \c mbedtls_ecp_mul()) is:
* - about 3300 basic operations for P-256
* - about 9400 basic operations for P-384
*
* \note Very low values are not always respected: sometimes
* functions need to block for a minimum number of
* operations, and will do so even if max_ops is set to a
* lower value. That minimum depends on the curve size, and
* can be made lower by decreasing the value of
* \c MBEDTLS_ECP_WINDOW_SIZE. As an indication, here is the
* lowest effective value for various curves and values of
* that parameter (w for short):
* w=6 w=5 w=4 w=3 w=2
* P-256 208 208 160 136 124
* P-384 682 416 320 272 248

* should make sure this is seen by the application as a new
* context (as it has been reset internally). Either way, you
* must make sure this is seen by the application as a new
* connection: application state, if any, should be reset, and
* most importantly the identity of the client must be checked
* again. WARNING: not validating the identity of the client
* again, or not transmitting the new identity to the
* application layer, would allow authentication bypass!

* - If the function returns MBEDTLS_ERR_SSL_WANT_READ, no datagram
* - If the function returns #MBEDTLS_ERR_SSL_WANT_READ, no datagram
* from the underlying transport layer is currently being processed,
* and it is safe to idle until the timer or the underlying transport
* signal a new event.

Mbed TLS sample programs
========================
This subdirectory mostly contains sample programs that illustrate specific features of the library, as well as a few test and support programs.
## Symmetric cryptography (AES) examples
* [`aes/aescrypt2.c`](aes/aescrypt2.c): file encryption and authentication with a key derived from a low-entropy secret, demonstrating the low-level AES interface, the digest interface and HMAC.
Warning: this program illustrates how to use low-level functions in the library. It should not be taken as an example of how to build a secure encryption mechanism. To derive a key from a low-entropy secret such as a password, use a standard key stretching mechanism such as PBKDF2 (provided by the `pkcs5` module). To encrypt and authenticate data, use a standard mode such as GCM or CCM (both available as library module).
* [`aes/crypt_and_hash.c`](aes/crypt_and_hash.c): file encryption and authentication, demonstrating the generic cipher interface and the generic hash interface.
## Hash (digest) examples
* [`hash/generic_sum.c`](hash/generic_sum.c): file hash calculator and verifier, demonstrating the message digest (`md`) interface.
* [`hash/hello.c`](hash/hello.c): hello-world program for MD5.
## Public-key cryptography examples
### Generic public-key cryptography (`pk`) examples
* [`pkey/gen_key.c`](pkey/gen_key.c): generates a key for any of the supported public-key algorithms (RSA or ECC) and writes it to a file that can be used by the other pk sample programs.
* [`pkey/key_app.c`](pkey/key_app.c): loads a PEM or DER public key or private key file and dumps its content.
* [`pkey/key_app_writer.c`](pkey/key_app_writer.c): loads a PEM or DER public key or private key file and writes it to a new PEM or DER file.
* [`pkey/pk_encrypt.c`](pkey/pk_encrypt.c), [`pkey/pk_decrypt.c`](pkey/pk_decrypt.c): loads a PEM or DER public/private key file and uses the key to encrypt/decrypt a short string through the generic public-key interface.
* [`pkey/pk_sign.c`](pkey/pk_sign.c), [`pkey/pk_verify.c`](pkey/pk_verify.c): loads a PEM or DER private/public key file and uses the key to sign/verify a short string.
### ECDSA and RSA signature examples
* [`pkey/ecdsa.c`](pkey/ecdsa.c): generates an ECDSA key, signs a fixed message and verifies the signature.
* [`pkey/rsa_encrypt.c`](pkey/rsa_encrypt.c), [`pkey/rsa_decrypt.c`](pkey/rsa_decrypt.c): loads an RSA public/private key and uses it to encrypt/decrypt a short string through the low-level RSA interface.
* [`pkey/rsa_genkey.c`](pkey/rsa_genkey.c): generates an RSA key and writes it to a file that can be used with the other RSA sample programs.
* [`pkey/rsa_sign.c`](pkey/rsa_sign.c), [`pkey/rsa_verify.c`](pkey/rsa_verify.c): loads an RSA private/public key and uses it to sign/verify a short string with the RSA PKCS#1 v1.5 algorithm.
* [`pkey/rsa_sign_pss.c`](pkey/rsa_sign_pss.c), [`pkey/rsa_verify_pss.c`](pkey/rsa_verify_pss.c): loads an RSA private/public key and uses it to sign/verify a short string with the RSASSA-PSS algorithm.
### Diffie-Hellman key exchange examples
* [`pkey/dh_client.c`](pkey/dh_client.c), [`pkey/dh_server.c`](pkey/dh_server.c): secure channel demonstrators (client, server). This pair of programs illustrates how to set up a secure channel using RSA for authentication and Diffie-Hellman to generate a shared AES session key.
* [`pkey/ecdh_curve25519.c`](pkey/ecdh_curve25519.c): demonstration of a elliptic curve Diffie-Hellman (ECDH) key agreement.
### Bignum (`mpi`) usage examples
* [`pkey/dh_genprime.c`](pkey/dh_genprime.c): shows how to use the bignum (`mpi`) interface to generate Diffie-Hellman parameters.
* [`pkey/mpi_demo.c`](pkey/mpi_demo.c): demonstrates operations on big integers.
## Random number generator (RNG) examples
* [`random/gen_entropy.c`](random/gen_entropy.c): shows how to use the default entropy sources to generate random data.
Note: most applications should only use the entropy generator to seed a cryptographic pseudorandom generator, as illustrated by `random/gen_random_ctr_drbg.c`.
* [`random/gen_random_ctr_drbg.c`](random/gen_random_ctr_drbg.c): shows how to use the default entropy sources to seed a pseudorandom generator, and how to use the resulting random generator to generate random data.
* [`random/gen_random_havege.c`](random/gen_random_havege.c): demonstrates the HAVEGE entropy collector.
## SSL/TLS examples
### SSL/TLS sample applications
* [`ssl/dtls_client.c`](ssl/dtls_client.c): a simple DTLS client program, which sends one datagram to the server and reads one datagram in response.
* [`ssl/dtls_server.c`](ssl/dtls_server.c): a simple DTLS server program, which expects one datagram from the client and writes one datagram in response. This program supports DTLS cookies for hello verification.
* [`ssl/mini_client.c`](ssl/mini_client.c): a minimalistic SSL client, which sends a short string and disconnects. This is primarily intended as a benchmark; for a better example of a typical TLS client, see `ssl/ssl_client1.c`.
* [`ssl/ssl_client1.c`](ssl/ssl_client1.c): a simple HTTPS client that sends a fixed request and displays the response.
* [`ssl/ssl_fork_server.c`](ssl/ssl_fork_server.c): a simple HTTPS server using one process per client to send a fixed response. This program requires a Unix/POSIX environment implementing the `fork` system call.
* [`ssl/ssl_mail_client.c`](ssl/ssl_mail_client.c): a simple SMTP-over-TLS or SMTP-STARTTLS client. This client sends an email with fixed content.
* [`ssl/ssl_pthread_server.c`](ssl/ssl_pthread_server.c): a simple HTTPS server using one thread per client to send a fixed response. This program requires the pthread library.
* [`ssl/ssl_server.c`](ssl/ssl_server.c): a simple HTTPS server that sends a fixed response. It serves a single client at a time.
### SSL/TLS feature demonstrators
Note: unlike most of the other programs under the `programs/` directory, these two programs are not intended as a basis for writing an application. They combine most of the features supported by the library, and most applications require only a few features. To write a new application, we recommended that you start with `ssl_client1.c` or `ssl_server.c`, and then look inside `ssl/ssl_client2.c` or `ssl/ssl_server2.c` to see how to use the specific features that your application needs.
* [`ssl/ssl_client2.c`](ssl/ssl_client2.c): an HTTPS client that sends a fixed request and displays the response, with options to select TLS protocol features and Mbed TLS library features.
* [`ssl/ssl_server2.c`](ssl/ssl_server2.c): an HTTPS server that sends a fixed response, with options to select TLS protocol features and Mbed TLS library features.
In addition to providing options for testing client-side features, the `ssl_client2` program has options that allow you to trigger certain behaviors in the server. For example, there are options to select ciphersuites, or to force a renegotiation. These options are useful for testing the corresponding features in a TLS server. Likewise, `ssl_server2` has options to activate certain behaviors that are useful for testing a TLS client.
## Test utilities
* [`test/benchmark.c`](test/benchmark.c): benchmark for cryptographic algorithms.
* [`test/selftest.c`](test/selftest.c): runs the self-test function in each library module.
* [`test/ssl_cert_test.c`](test/ssl_cert_test.c): demonstrates how to verify X.509 certificates, and (for RSA keys only) how to check that each certificate matches the corresponding private key. This program requires some test data which is not provided.
* [`test/udp_proxy.c`](test/udp_proxy.c): a UDP proxy that can inject certain failures (delay, duplicate, drop). Useful for testing DTLS.
* [`test/zeroize.c`](test/zeroize.c): a test program for `mbedtls_platform_zeroize`, used by [`tests/scripts/test_zeroize.gdb`](tests/scripts/test_zeroize.gdb).
## Development utilities
* [`util/pem2der.c`](util/pem2der.c): a PEM to DER converter. Mbed TLS can read PEM files directly, but this utility can be useful for interacting with other tools or with minimal Mbed TLS builds that lack PEM support.
* [`util/strerror.c`](util/strerror.c): prints the error description corresponding to an integer status returned by an Mbed TLS function.
## X.509 certificate examples
* [`x509/cert_app.c`](x509/cert_app.c): connects to a TLS server and verifies its certificate chain.
* [`x509/cert_req.c`](x509/cert_req.c): generates a certificate signing request (CSR) for a private key.
* [`x509/cert_write.c`](x509/cert_write.c): signs a certificate signing request, or self-signs a certificate.
* [`x509/crl_app.c`](x509/crl_app.c): loads and dumps a certificate revocation list (CRL).
* [`x509/req_app.c`](x509/req_app.c): loads and dumps a certificate signing request (CSR).

Two intermediate CAs are signed by them:
- test-int-ca.crt "C=NL, O=PolarSSL, CN=PolarSSL Test Intermediate CA"
uses RSA-4096, signed by test-ca2
- test-int-ca-exp.crt is a copy that is expired
