 mbed TLS ChangeLog (Sorted per branch, date)
 
+= mbed TLS x.x.x branch released xxxx-xx-xx
+
+Security
+   * Fix a potential heap buffer overflow in mbedtls_ssl_write. When the (by
+     default enabled) maximum fragment length extension is disabled in the
+     config and the application data buffer passed to mbedtls_ssl_write
+     is larger than the internal message buffer (16384 bytes by default), the
+     latter overflows. The exploitability of this issue depends on whether the
+     application layer can be forced into sending such large packets. The issue
+     was independently reported by Tim Nordell via e-mail and by Florin Petriuc
+     and sjorsdewit on GitHub. Fix proposed by Florin Petriuc in #1022. Fixes #707.
+
+Features
+   * Allow comments in test data files.
+
+Bugfix
+   * Fix ssl_parse_record_header() to silently discard invalid DTLS records
+     as recommended in RFC 6347 Section 4.1.2.7.
+   * Fix memory leak in mbedtls_ssl_set_hostname() when called multiple times.
+     Found by projectgus and jethrogb, #836.
+   * Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.
+   * Parse signature algorithm extension when renegotiating. Previously,
+     renegotiated handshakes would only accept signatures using SHA-1
+     regardless of the peer's preferences, or fail if SHA-1 was disabled.
+   * Fix leap year calculation in x509_date_is_valid() to ensure that invalid
+     dates on leap years with 100 and 400 intervals are handled correctly. Found
+     by Nicholas Wilson. #694
+   * Fix out-of-memory problem when parsing 4096-bit PKCS8-encrypted RSA keys.
+     Found independently by Florian in the mbed TLS forum and by Mishamax.
+     #878, #1019.
+   * Fix variable used before assignment compilation warnings with IAR
+     toolchain. Found by gkerrien38.
+   * Fix unchecked return codes from AES, DES and 3DES functions in
+     pem_aes_decrypt(), pem_des_decrypt() and pem_des3_decrypt() respectively.
+     If a call to one of the functions of the cryptographic primitive modules
+     failed, the error may not be noticed by the function
+     mbedtls_pem_read_buffer() causing it to return invalid values. Found by
+     Guido Vranken. #756
+   * Include configuration file in md.h, to fix compilation warnings.
+     Reported by aaronmdjones in #1001
+   * Correct extraction of signature-type from PK instance in X.509 CRT and CSR
+     writing routines that prevented these functions to work with alternative
+     RSA implementations. Raised by J.B. in the Mbed TLS forum. Fixes #1011.
+   * Don't print X.509 version tag for v1 CRT's, and omit extensions for
+     non-v3 CRT's.
+   * Fix bugs in RSA test suite under MBEDTLS_NO_PLATFORM_ENTROPY. #1023 #1024
+   * Fix net_would_block to avoid modification by errno through fcntl call.
+     Found by nkolban. Fixes #845.
+   * Fix handling of handshake messages in mbedtls_ssl_read in case
+     MBEDTLS_SSL_RENEGOTIATION is disabled. Found by erja-gp.
+   * Add a check for invalid private parameters in mbedtls_ecdsa_sign.
+     Reported by Yolan Romailler.
+   * Fix word size check in in pk.c to not depend on MBEDTLS_HAVE_INT64.
+   * Fix incorrect unit in benchmark output. #850
+
+Changes
+   * Extend cert_write example program by options to set the CRT version
+     and the message digest. Further, allow enabling/disabling of authority
+     identifier, subject identifier and basic constraints extensions.
+
+= mbed TLS 2.6.0 branch released 2017-08-10
+
+Security
+   * Fix authentication bypass in SSL/TLS: when authmode is 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
+     (default: 8) intermediates, even when it was not trusted. This could be
+     triggered remotely from either side. (With authmode set to 'required'
+     (the default), the handshake was correctly aborted).
+   * Reliably wipe sensitive data after use in the AES example applications
+     programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
+     Found by Laurent Simon.
+
+Features
+   * Add the functions mbedtls_platform_setup() and mbedtls_platform_teardown()
+     and the context struct mbedtls_platform_context to perform
+     platform-specific setup and teardown operations. The macro
+     MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT allows the functions to be overridden
+     by the user in a platform_alt.h file. These new functions are required in
+     some embedded environments to provide a means of initialising underlying
+     cryptographic acceleration hardware.
+
+API Changes
+   * Reverted API/ABI breaking changes introduced in mbed TLS 2.5.1, to make the
+     API consistent with mbed TLS 2.5.0. Specifically removed the inline
+     qualifier from the functions mbedtls_aes_decrypt, mbedtls_aes_encrypt,
+     mbedtls_ssl_ciphersuite_uses_ec and mbedtls_ssl_ciphersuite_uses_psk. Found
+     by James Cowgill. #978
+   * Certificate verification functions now set flags to -1 in case the full
+     chain was not verified due to an internal error (including in the verify
+     callback) or chain length limitations.
+   * With authmode set to optional, the TLS handshake is now aborted if the
+     verification of the peer's certificate failed due to an overlong chain or
+     a fatal error in the verify callback.
+
+Bugfix
+   * Add a check if iv_len is zero in GCM, and return an error if it is zero.
+     Reported by roberto. #716
+   * Replace preprocessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
+     to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
+     always be implemented by pthread support. #696
+   * Fix a resource leak on Windows platforms in mbedtls_x509_crt_parse_path(),
+     in the case of an error. Found by redplait. #590
+   * Add MBEDTLS_MPI_CHK to check for error value of mbedtls_mpi_fill_random.
+     Reported and fix suggested by guidovranken. #740
+   * Fix conditional preprocessor directives in bignum.h to enable 64-bit
+     compilation when using ARM Compiler 6.
+   * Fix a potential integer overflow in the version verification for DER
+     encoded X.509 CRLs. The overflow could enable maliciously constructed CRLs
+     to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
+     KNOX Security, Samsung Research America
+   * Fix potential integer overflow in the version verification for DER
+     encoded X.509 CSRs. The overflow could enable maliciously constructed CSRs
+     to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
+     KNOX Security, Samsung Research America
+   * Fix a potential integer overflow in the version verification for DER
+     encoded X.509 certificates. The overflow could enable maliciously
+     constructed certificates to bypass the certificate verification check.
+   * Fix a call to the libc function time() to call the platform abstraction
+     function mbedtls_time() instead. Found by wairua. #666
+   * Avoid shadowing of time and index functions through mbed TLS function
+     arguments. Found by inestlerode. #557.
+
+Changes
+   * Added config.h option MBEDTLS_NO_UDBL_DIVISION, to prevent the use of
+     64-bit division. This is useful on embedded platforms where 64-bit division
+     created a dependency on external libraries. #708
+   * Removed mutexes from ECP hardware accelerator code. Now all hardware
+     accelerator code in the library leaves concurrency handling to the
+     platform. Reported by Steven Cooreman. #863
+   * Define the macro MBEDTLS_AES_ROM_TABLES in the configuration file
+     config-no-entropy.h to reduce the RAM footprint.
+   * Added a test script that can be hooked into git that verifies commits
+     before they are pushed.
+   * Improve documentation of PKCS1 decryption functions.
+
+= mbed TLS 2.5.1 released 2017-06-21
+
+Security
+   * Fixed unlimited overread of heap-based buffer in mbedtls_ssl_read().
+     The issue could only happen client-side with renegotiation enabled.
+     Could result in DoS (application crash) or information leak
+     (if the application layer sent data read from mbedtls_ssl_read()
+     back to the server or to a third party). Can be triggered remotely.
+   * Removed SHA-1 and RIPEMD-160 from the default hash algorithms for
+     certificate verification. SHA-1 can be turned back on with a compile-time
+     option if needed.
+   * Fixed offset in FALLBACK_SCSV parsing that caused TLS server to fail to
+     detect it sometimes. Reported by Hugo Leisink. #810
+   * Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
+     potential Bleichenbacher/BERserk-style attack.
+
+Bugfix
+   * Remove size zero arrays from ECJPAKE test suite. Size zero arrays are not
+     valid C and they prevented the test from compiling in Visual Studio 2015
+     and with GCC using the -Wpedantic compilation option.
+   * Fix insufficient support for signature-hash-algorithm extension,
+     resulting in compatibility problems with Chrome. Found by hfloyrd. #823
+   * Fix behaviour that hid the original cause of fatal alerts in some cases
+     when sending the alert failed. The fix makes sure not to hide the error
+     that triggered the alert.
+   * Fix SSLv3 renegotiation behaviour and stop processing data received from
+     peer after sending a fatal alert to refuse a renegotiation attempt.
+     Previous behaviour was to keep processing data even after the alert has
+     been sent.
+   * Accept empty trusted CA chain in authentication mode
+     MBEDTLS_SSL_VERIFY_OPTIONAL.
+     Found by jethrogb. #864
+   * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
+     fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
+     reflect bad EC curves within verification result.
+   * Fix bug that caused the modular inversion function to accept the invalid
+     modulus 1 and therefore to hang. Found by blaufish. #641.
+   * Fix incorrect sign computation in modular exponentiation when the base is
+     a negative MPI. Previously the result was always negative. Found by Guido
+     Vranken.
+   * Fix a numerical underflow leading to stack overflow in mpi_read_file()
+     that was triggered uppon reading an empty line. Found by Guido Vranken.
+
+Changes
+   * Send fatal alerts in more cases. The previous behaviour was to skip
+     sending the fatal alert and just drop the connection.
+   * Clarify ECDSA documentation and improve the sample code to avoid
+     misunderstanding and potentially dangerous use of the API. Pointed out
+     by Jean-Philippe Aumasson.
+
+= mbed TLS 2.5.0 branch released 2017-05-17
+
+Security
+   * Wipe stack buffers in RSA private key operations
+     (rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt). Found by Laurent
+     Simon.
+   * Add exponent blinding to RSA private operations as a countermeasure
+     against side-channel attacks like the cache attack described in
+     https://arxiv.org/abs/1702.08719v2.
+     Found and fix proposed by Michael Schwarz, Samuel Weiser, Daniel Gruss,
+     Clémentine Maurice and Stefan Mangard.
+
+Features
+   * Add hardware acceleration support for the Elliptic Curve Point module.
+     This involved exposing parts of the internal interface to enable
+     replacing the core functions and adding and alternative, module level
+     replacement support for enabling the extension of the interface.
+   * Add a new configuration option to 'mbedtls_ssl_config' to enable
+     suppressing the CA list in Certificate Request messages. The default
+     behaviour has not changed, namely every configured CAs name is included.
+
+API Changes
+   * The following functions in the AES module have been deprecated and replaced
+     by the functions shown below. The new functions change the return type from
+     void to int to allow returning error codes when using MBEDTLS_AES_ALT,
+     MBEDTLS_AES_DECRYPT_ALT or MBEDTLS_AES_ENCRYPT_ALT.
+     mbedtls_aes_decrypt() -> mbedtls_internal_aes_decrypt()
+     mbedtls_aes_encrypt() -> mbedtls_internal_aes_encrypt()
+
+Bugfix
+   * Remove macros from compat-1.3.h that correspond to deleted items from most
+     recent versions of the library. Found by Kyle Keen.
+   * Fixed issue in the Threading module that prevented mutexes from
+     initialising. Found by sznaider. #667 #843
+   * Add checks in the PK module for the RSA functions on 64-bit systems.
+     The PK and RSA modules use different types for passing hash length and
+     without these checks the type cast could lead to data loss. Found by Guido
+     Vranken.

 -------------
 
-mbed TLS should build out of the box on most systems. Some platform specific options are available in the fully documented configuration file `include/mbedtls/config.h`, which is also the place where features can be selected. This file can be edited manually, or in a more programmatic way using the Perl script `scripts/config.pl` (use `--help` for usage instructions).

This file can be edited manually, or in a more programmatic way using the Perl script `scripts/config.pl` (use `--help` for usage instructions).
 
 Compiler options can be set using conventional environment variables such as `CC` and `CFLAGS` when using the Make and CMake build system (see below).

+-   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.

-We intentionally only use the minimum of `Make` functionality, as a lot of `Make` features are not supported on all different implementations of Make or on different platforms. As such, the Makefiles sometimes require some manual changes or export statements in order to work for your platform.
+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; if you do so, essential parts such as `-I` will still be preserved. Warning options may be overridden separately using `WARNING_CFLAGS`.

+ *
+ * The platform lacks support for double-width integer division (64-bit
+ * division on a 32-bit platform, 128-bit division on a 64-bit platform).
+ *
+ * Used in:
+ *      include/mbedtls/bignum.h
+ *      library/bignum.c
+ *
+ * The bignum code uses double-width division to speed up some operations.
+ * Double-width division is often implemented in software that needs to
+ * be linked with the program. The presence of a double-width integer
+ * type is usually detected automatically through preprocessor macros,
+ * but the automatic detection cannot know whether the code needs to
+ * and can be linked with an implementation of division for that type.
+ * By default division is assumed to be usable if the type is present.
+ * Uncomment this option to prevent the use of double-width division.
+ *
+ * Note that division for the native integer type is always required.
+ * Furthermore, a 64-bit type is always required even on a 32-bit
+ * platform, but it need not support multiplication or division. In some
+ * cases it is also desirable to disable some double-width operations. For
+ * example, if double-width division is implemented in software, disabling
+ * it can reduce code size in some embedded targets.

+ * \note        A clarification on what is called 'record layer' here
+ *              is in order, as many sensible definitions are possible:
+ *
+ *              The record layer takes as input an untrusted underlying
+ *              transport (stream or datagram) and transforms it into
+ *              a serially multiplexed, secure transport, which
+ *              conceptually provides the following:
+ *
+ *              (1) Three datagram based, content-agnostic transports
+ *                  for handshake, alert and CCS messages.
+ *              (2) One stream- or datagram-based transport
+ *                  for application data.
+ *              (3) Functionality for changing the underlying transform
+ *                  securing the contents.
+ *
+ *              The interface to this functionality is given as follows:
+ *
+ *              a Updating
+ *                [Currently implemented by mbedtls_ssl_read_record]
+ *
+ *                Check if and on which of the four 'ports' data is pending:
+ *                Nothing, a controlling datagram of type (1), or application
+ *                data (2). In any case data is present, internal buffers
+ *                provide access to the data for the user to process it.
+ *                Consumption of type (1) datagrams is done automatically
+ *                on the next update, invalidating that the internal buffers
+ *                for previous datagrams, while consumption of application
+ *                data (2) is user-controlled.
+ *
+ *              b Reading of application data
+ *                [Currently manual adaption of ssl->in_offt pointer]
+ *
+ *                As mentioned in the last paragraph, consumption of data
+ *                is different from the automatic consumption of control
+ *                datagrams (1) because application data is treated as a stream.
+ *
+ *              c Tracking availability of application data
+ *                [Currently manually through decreasing ssl->in_msglen]
+ *
+ *                For efficiency and to retain datagram semantics for
+ *                application data in case of DTLS, the record layer
+ *                provides functionality for checking how much application
+ *                data is still available in the internal buffer.
+ *
+ *              d Changing the transformation securing the communication.
+ *
+ *              Given an opaque implementation of the record layer in the
+ *              above sense, it should be possible to implement the logic
+ *              of (D)TLS on top of it without the need to know anything
+ *              about the record layer's internals. This is done e.g.
+ *              in all the handshake handling functions, and in the
+ *              application data reading function mbedtls_ssl_read.
+ *
+ * \note        The above tries to give a conceptual picture of the
+ *              record layer, but the current implementation deviates
+ *              from it in some places. For example, our implementation of
+ *              the update functionality through mbedtls_ssl_read_record
+ *              discards datagrams depending on the current state, which
+ *              wouldn't fall under the record layer's responsibility
+ *              following the above definition.

+     * - Fetching a new record if yes

+     * - Adapt read_record to set ssl->in_offt automatically
+     *   when a new application data record is processed.
+     * - Always call mbedtls_ssl_read_record here.
+     *
+     * This way, the logic of ssl_read would be much clearer:
+     *
+     * (1) Always call record layer and see what kind of record is on
+     *     and have it ready for consumption (in particular, in_offt
+     *     properly set for application data records).
+     * (2) If it's application data (either freshly fetched
+     *     or something already being partially processed),
+     *     serve the read request from it.
+     * (3) If it's something different from application data,
+     *     handle it accordingly, e.g. potentially start a
+     *     renegotiation.
+     *
+     * This will also remove the need to manually reset

+Newer test files have been generated through commands in the Makefile. The
+resulting files are committed to the repository so that the tests can
+run without having to re-do the generation and so that the output is the

+README for git hooks script
+===========================
+git has a way to run scripts, which are invoked by specific git commands.
+The git hooks are located in `<mbed TLS root>/.git/hooks`, and as such are not under version control
+for more information, see the [git documentation](https://git-scm.com/docs/githooks).
+
+The mbed TLS git hooks are located in `<mbed TLS root>/tests/git-scripts` directory, and one must create a soft link from `<mbed TLS root>/.git/hooks` to `<mbed TLS root>/tesst/git-scripts`, in order to make the hook scripts successfully work.
+
+Example:
+
+Execute the following command to create a link on linux from the mbed TLS `.git/hooks` directory:  
+`ln -s ../../tests/git-scripts/pre-push.sh pre-push`
+
+**Note: Currently the mbed TLS git hooks work only on a GNU platform. If using a non-GNU platform, don't enable these hooks!**
+
+These scripts can also be used independently.

+# Purpose

+# Called by "git push" after it has checked the remote status, but before anything has been
+# pushed.  If this script exits with a non-zero status nothing will be pushed.
+# This script can also be used independently, not using git.

+# This hook is called with the following parameters:

+# $1 -- Name of the remote to which the push is being done
+# $2 -- URL to which the push is being done
+#
+# If pushing without using a named remote those arguments will be equal.
+#
+# Information about the commits which are being pushed is supplied as lines to
+# the standard input in the form:
