+Contributing
+============
+We gratefully accept bug reports and contributions from the community. There are some requirements we need to fulfill in order to be able to integrate contributions:
+
+ - As with any open source project, contributions will be reviewed by the project team and community and may need some modifications to be accepted.
+ - The contribution should not break API or ABI, unless there is a real justification for that. If there is an API change, the contribution, if accepted, will be merged only when there will be a major release.
+
+Contributor License Agreement (CLA)
+-----------------------------------
+- All contributions, whether large or small, require a Contributor's License Agreement (CLA) to be accepted. This is because source code can possibly fall under copyright law and we need your consent to share in the ownership of the copyright.
+- To accept the Contributor’s License Agreement (CLA), individual contributors can do this by creating an Mbed account and [accepting the online agreement here with a click through](https://developer.mbed.org/contributor_agreement/). Alternatively, for contributions from corporations, or those that do not wish to create an Mbed account, a slightly different agreement can be found [here](https://www.mbed.com/en/about-mbed/contributor-license-agreements/). This agreement should be signed and returned to Arm as described in the instructions given.
+
+Coding Standards
+----------------
+- We would ask that contributions conform to [our coding standards](https://tls.mbed.org/kb/development/mbedtls-coding-standards), and that contributions are fully tested before submission, as mentioned in the [Tests](#tests) and [Continuous Integration](#continuous-integration-tests) sections.
+- The code should be written in a clean and readable style.
+- The code should be written in a portable generic way, that will benefit the whole community, and not only your own needs.
+- The code should be secure, and will be reviewed from a security point of view as well.
+
+Making a Contribution
+---------------------
+1. [Check for open issues](https://github.com/ARMmbed/mbedtls/issues) or [start a discussion](https://tls.mbed.org/discussions) around a feature idea or a bug.
+1. Fork the [Mbed TLS repository on GitHub](https://github.com/ARMmbed/mbedtls) to start making your changes. As a general rule, you should use the ["development" branch](https://github.com/ARMmbed/mbedtls/tree/development) as a basis.
+1. Write a test which shows that the bug was fixed or that the feature works as expected.
+1. Send a pull request (PR) and work with us until it gets merged and published. Contributions may need some modifications, so a few rounds of review and fixing may be necessary. We will include your name in the ChangeLog :)
+1. For quick merging, the contribution should be short, and concentrated on a single feature or topic. The larger the contribution is, the longer it would take to review it and merge it.
+1. Mbed TLS is released under the Apache license, and as such, all the added files should include the Apache license header.
+
+Backports
+---------
+Mbed TLS maintains some legacy branches, which are released as LTS versions. Mbed TLS should follow backwards compatibility rules, to fit with existing users. As such, backporting to these branches should be handled according to the following rules:
+  
+1. If the contribution is a new feature or enhancement, no backporting is needed.
+1. Bug fixes should be backported to the legacy branches containing these bugs.
+1. Changes in the API do not require backporting. If a bug fix introduced a new API, such as new error codes, the bug fix should be implemented differently in the legacy branch.
+
+It would be highly appreciated if a contribution would be backported to a legacy branch in addition to the [development branch](https://github.com/ARMmbed/mbedtls/tree/development).
+At the moment, the legacy branches are:
+  
+1. [mbedtls-1.3](https://github.com/ARMmbed/mbedtls/tree/mbedtls-1.3)
+1. [mbedtls-2.1](https://github.com/ARMmbed/mbedtls/tree/mbedtls-2.1)
+
+Tests
+-----
+As mentioned, tests that show the correctness of the feature or bug fix should be added to the pull request, if no such tests exist.  
+Mbed TLS includes an elaborate test suite in `tests/` that initially requires Perl to generate the tests files (e.g. `test_suite_mpi.c`). These files are generated from a `function file` (e.g. `suites/test_suite_mpi.function`) and a `data file` (e.g. `suites/test_suite_mpi.data`). The function file contains the test functions. The data file contains the test cases, specified as parameters that will be passed to the test function.
+
+Sample applications, if needed, should be modified as well.
+
+Continuous Integration Tests
+----------------------------
+Once a PR has been made, the Continuous Integration (CI) tests are triggered and run. You should follow the result of the CI tests, and fix failures. 
+It is advised to enable the [githooks scripts](https://github.com/ARMmbed/mbedtls/tree/development/tests/git-scripts) prior to pushing your changes, for catching some of the issues as early as possible.
+
+Documentation
+-------------
+Mbed TLS should be well documented. If documentation is needed, speak out!
+
+1. All interfaces should be documented through Doxygen. New APIs should introduce Doxygen documentation.
+1. Complex parts in the code should include comments.
+1. If needed, a Readme file is advised.
+1. If a [Knowledge Base (KB)](https://tls.mbed.org/kb) article should be added, write this as a comment in the PR description.
+1. A [ChangeLog](https://github.com/ARMmbed/mbedtls/blob/development/ChangeLog) entry should be added for this contribution.

    * Add support for ARIA cipher (RFC 5794) and associated TLS ciphersuites
      (RFC 6209). Disabled by default, see MBEDTLS_ARIA_C in config.h
 
-= mbed TLS 2.7.x branch released 2018-xx-xx
+API Changes
+   * Extend the platform module with a util component that contains
+     functionality shared by multiple Mbed TLS modules. At this stage
+     platform_util.h (and its associated platform_util.c) only contain
+     mbedtls_platform_zeroize(), which is a critical function from a security
+     point of view. mbedtls_platform_zeroize() needs to be regularly tested
+     against compilers to ensure that calls to it are not removed from the
+     output binary as part of redundant code elimination optimizations.
+     Therefore, mbedtls_platform_zeroize() is moved to the platform module to
+     facilitate testing and maintenance.
+
+= mbed TLS 2.9.0 branch released 2018-04-30
+
+Security
+   * Fix an issue in the X.509 module which could lead to a buffer overread
+     during certificate validation. Additionally, the issue could also lead to
+     unnecessary callback checks being made or to some validation checks to be
+     omitted. The overread could be triggered remotely, while the other issues
+     would require a non DER-compliant certificate to be correctly signed by a
+     trusted CA, or a trusted CA with a non DER-compliant certificate. Found by
+     luocm. Fixes #825.
+   * Fix the buffer length assertion in the ssl_parse_certificate_request()
+     function which led to an arbitrary overread of the message buffer. The
+     overreads could be caused by receiving a malformed message at the point
+     where an optional signature algorithms list is expected when the signature
+     algorithms section is too short. In builds with debug output, the overread
+     data is output with the debug data.
+   * Fix a client-side bug in the validation of the server's ciphersuite choice
+     which could potentially lead to the client accepting a ciphersuite it didn't
+     offer or a ciphersuite that cannot be used with the TLS or DTLS version
+     chosen by the server. This could lead to corruption of internal data
+     structures for some configurations.
+
+Features
+   * Add an option, MBEDTLS_AES_FEWER_TABLES, to dynamically compute smaller AES
+     tables during runtime, thereby reducing the RAM/ROM footprint by ~6KiB.
+     Suggested and contributed by jkivilin in pull request #394.
+   * Add initial support for Curve448 (RFC 7748). Only mbedtls_ecp_mul() and
+     ECDH primitive functions (mbedtls_ecdh_gen_public(),
+     mbedtls_ecdh_compute_shared()) are supported for now. Contributed by
+     Nicholas Wilson in pull request #348.
+
+API Changes
+   * Extend the public API with the function of mbedtls_net_poll() to allow user
+     applications to wait for a network context to become ready before reading
+     or writing.
+   * Add function mbedtls_ssl_check_pending() to the public API to allow
+     a check for whether more more data is pending to be processed in the
+     internal message buffers.
+     This function is necessary to determine when it is safe to idle on the
+     underlying transport in case event-driven IO is used.
+
+Bugfix
+   * Fix a spurious uninitialized variable warning in cmac.c. Fix independently
+     contributed by Brian J Murray and David Brown.
+   * Add missing dependencies in test suites that led to build failures
+     in configurations that omit certain hashes or public-key algorithms.
+     Fixes #1040.
+   * Fix C89 incompatibility in benchmark.c. Contributed by Brendan Shanks.
+     #1353
+   * Add missing dependencies for MBEDTLS_HAVE_TIME_DATE and
+     MBEDTLS_VERSION_FEATURES in some test suites. Contributed by
+     Deomid Ryabkov. Fixes #1299, #1475.
+   * Fix the Makefile build process for building shared libraries on Mac OS X.
+     Fixed by mnacamura.
+   * Fix parsing of PKCS#8 encoded Elliptic Curve keys. Previously Mbed TLS was
+     unable to parse keys which had only the optional parameters field of the
+     ECPrivateKey structure. Found by Jethro Beekman, fixed in #1379.
+   * Return the plaintext data more quickly on unpadded CBC decryption, as
+     stated in the mbedtls_cipher_update() documentation. Contributed by
+     Andy Leiserson.
+   * Fix overriding and ignoring return values when parsing and writing to
+     a file in pk_sign program. Found by kevlut in #1142.
+   * Restrict usage of error code MBEDTLS_ERR_SSL_WANT_READ to situations
+     where data needs to be fetched from the underlying transport in order
+     to make progress. Previously, this error code was also occasionally
+     returned when unexpected messages were being discarded, ignoring that
+     further messages could potentially already be pending to be processed
+     in the internal buffers; these cases led to deadlocks when event-driven
+     I/O was used. Found and reported by Hubert Mis in #772.
+   * Fix buffer length assertions in the ssl_parse_certificate_request()
+     function which leads to a potential one byte overread of the message
+     buffer.
+   * Fix invalid buffer sizes passed to zlib during record compression and
+     decompression.
+   * Fix the soversion of libmbedcrypto to match the soversion of the
+     maintained 2.7 branch. The soversion was increased in Mbed TLS
+     version 2.7.1 to reflect breaking changes in that release, but the
+     increment was missed in 2.8.0 and later releases outside of the 2.7 branch.
+
+Changes
+   * Remove some redundant code in bignum.c. Contributed by Alexey Skalozub.
+   * Support cmake builds where Mbed TLS is a subproject. Fix contributed
+     independently by Matthieu Volat and Arne Schwabe.
+   * Improve testing in configurations that omit certain hashes or
+     public-key algorithms. Includes contributions by Gert van Dijk.
+   * Improve negative testing of X.509 parsing.
+   * Do not define global mutexes around readdir() and gmtime() in
+     configurations where the feature is disabled. Found and fixed by Gergely
+     Budai.
+   * Harden the function mbedtls_ssl_config_free() against misuse, so that it
+     doesn't leak memory if the user doesn't use mbedtls_ssl_conf_psk() and
+     instead incorrectly manipulates the configuration structure directly.
+     Found and fix submitted by junyeonLEE in #1220.
+   * Provide an empty implementation of mbedtls_pkcs5_pbes2() when
+     MBEDTLS_ASN1_PARSE_C is not enabled. This allows the use of PBKDF2
+     without PBES2. Fixed by Marcos Del Sol Vives.
+   * Add the order of the base point as N in the mbedtls_ecp_group structure
+     for Curve25519 (other curves had it already). Contributed by Nicholas
+     Wilson #481
+   * Improve the documentation of mbedtls_net_accept(). Contributed by Ivan
+     Krylov.
+   * Improve the documentation of mbedtls_ssl_write(). Suggested by
+     Paul Sokolovsky in #1356.
+   * Add an option in the Makefile to support ar utilities where the operation
+     letter must not be prefixed by '-', such as LLVM. Found and fixed by
+     Alex Hixon.
+   * Allow configuring the shared library extension by setting the DLEXT
+     environment variable when using the project makefiles.
+   * Optimize unnecessary zeroing in mbedtls_mpi_copy. Based on a contribution
+     by Alexey Skalozub in #405.
+   * In the SSL module, when f_send, f_recv or f_recv_timeout report
+     transmitting more than the required length, return an error. Raised by
+     Sam O'Connor in #1245.
+   * Improve robustness of mbedtls_ssl_derive_keys against the use of
+     HMAC functions with non-HMAC ciphersuites. Independently contributed
+     by Jiayuan Chen in #1377. Fixes #1437.
+   * Improve security of RSA key generation by including criteria from
+     FIPS 186-4. Contributed by Jethro Beekman. #1380
+   * Declare functions in header files even when an alternative implementation
+     of the corresponding module is activated by defining the corresponding
+     MBEDTLS_XXX_ALT macro. This means that alternative implementations do
+     not need to copy the declarations, and ensures that they will have the
+     same API.
+   * Add platform setup and teardown calls in test suites.

+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.

 There are many different build modes available within the CMake buildsystem. Most of them are available for gcc and clang, though some are compiler-specific:
 
--   Release. This generates the default code without any unnecessary information in the binary files.
--   Debug. This generates debug information and disables optimization of the code.
--   Coverage. This generates code coverage information in addition to debug information.
--   ASan. This instruments the code with AddressSanitizer to check for memory errors. (This includes LeakSanitizer, with recent version of gcc and clang.) (With recent version of clang, this mode also instruments the code with UndefinedSanitizer to check for undefined behaviour.)
--   ASanDbg. Same as ASan but slower, with debug information and better stack traces.
--   MemSan. This instruments the code with MemorySanitizer to check for uninitialised memory reads. Experimental, needs recent clang on Linux/x86\_64.
--   MemSanDbg. Same as MemSan but slower, with debug information, better stack traces and origin tracking.
--   Check. This activates the compiler warnings that depend on optimization and treats all warnings as errors.

 Switching build modes in CMake is simple. For debug mode, enter at the command line:
 
-    cmake -D CMAKE_BUILD_TYPE=Debug .
+    cmake -D CMAKE_BUILD_TYPE=Debug /path/to/mbedtls_source
 
 To list other available CMake options, use:
 
     cmake -LH
 
-Note that, with CMake, if you want to change the compiler or its options after you already ran CMake, you need to clear its cache first, e.g. (using GNU find):
+Note that, with CMake, you can't adjust the compiler or its flags after the
+initial invocation of cmake. This means that `CC=your_cc make` and `make
+CC=your_cc` will *not* work (similarly with `CFLAGS` and other variables).
+These variables need to be adjusted when invoking cmake for the first time,
+for example:
+
+    CC=your_cc cmake /path/to/mbedtls_source
+
+If you already invoked cmake and want to change those settings, you need to
+remove the build directory and create it again.
+
+Note that it is possible to build in-place; this will however overwrite the
+provided Makefiles (see `scripts/tmp_ignore_makefiles.sh` if you want to
+prevent `git status` from showing them as modified). In order to do so, from
+the Mbed TLS source directory, use:
+
+    cmake .
+    make
+
+If you want to change `CC` or `CFLAGS` afterwards, you will need to remove the
+CMake cache. This can be done with the following command using GNU find:
 
     find . -iname '*cmake*' -not -name CMakeLists.txt -exec rm -rf {} +
-    CC=gcc CFLAGS='-fstack-protector-strong -Wa,--noexecstack' cmake .
+
+You can now make the desired change:
+
+    CC=your_cc cmake .
+    make
+
+Regarding variables, also note that if you set CFLAGS when invoking cmake,
+your value of CFLAGS doesn't override the content provided by cmake (depending
+on the build mode as seen above), it's merely prepended to it.

+ *                   been only e.g. duplicated messages or a renegotiation request.

+ *                   when reacting to an incoming-data event from the underlying transport.
+ *                 - On success, the datagram of the underlying transport that is currently

+ * Percival's blog article at:
+ *
+ * http://www.daemonology.net/blog/2014-09-04-how-to-zero-a-buffer.html
+ *
+ * It uses a volatile function pointer to the standard memset(). Because the
+ * pointer is volatile the compiler expects it to change at
+ * any time and will not optimize out the call that could potentially perform
+ * other operations on the input buffer instead of just setting it to 0.
+ * Nevertheless, as pointed out by davidtgoldblatt on Hacker News
+ * (refer to http://www.daemonology.net/blog/2014-09-05-erratum.html for
+ * details), optimizations of the following form are still possible:
+ *
+ * if( memset_func != memset )
+ *     memset_func( buf, 0, len );
+ *
+ * Note that it is extremely difficult to guarantee that
+ * mbedtls_platform_zeroize() will not be optimized out by aggressive compilers
+ * in a portable way. For this reason, Mbed TLS also provides the configuration
+ * option MBEDTLS_PLATFORM_ZEROIZE_ALT, which allows users to configure
+ * mbedtls_platform_zeroize() to use a suitable implementation for their
+ * platform and needs.

-     * The logic should be streamlined here:
-     *
-     * Instead of
-     *
-     * - Manually checking whether ssl->in_offt is NULL
-     * - Fetching a new record if yes
-     * - Setting ssl->in_offt if one finds an application record
-     * - Resetting keep_current_message after handling the application data

-     * one should
-     *
-     * - 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
-     * ssl->keep_current_message = 0 below.

+ *  3. for trusted roots, the signature is correct

+ * If there's a suitable candidate which is also time-valid, return the first

+ *
+ * The rationale for this rule is that someone could have a list of trusted
+ * roots with two versions on the same root with different validity periods.
+ * (At least one user reported having such a list and wanted it to just work.)
+ * The reason we don't just require time-validity is that generally there is
+ * only one version, and if it's expired we want the flags to state that
+ * rather than NOT_TRUSTED, as would be the case if we required it here.
+ *
+ * The rationale for rule 3 (signature for trusted roots) is that users might
+ * have two versions of the same CA with different keys in their list, and the
+ * way we select the correct one is by checking the signature (as we don't
+ * rely on key identifier extensions). (This is one way users might choose to
+ * handle key rollover, another relies on self-issued certs, see [SIRO].)
+ *
+ * Arguments:
+ *  - [in] child: certificate for which we're looking for a parent
+ *  - [in] candidates: chained list of potential parents
+ *  - [in] top: 1 if candidates consists of trusted roots, ie we're at the top
+ *         of the chain, 0 otherwise
+ *  - [in] path_cnt: number of intermediates seen so far
+ *  - [in] self_cnt: number of self-signed intermediates seen so far
+ *         (will never be greater than path_cnt)

+This file is part of Mbed TLS (https://tls.mbed.org)
+
+Copyright (c) 2018, Arm Limited, All Rights Reserved
+
+Purpose
+
+This script is a small wrapper around the abi-compliance-checker and
+abi-dumper tools, applying them to compare the ABI and API of the library
+files from two different Git revisions within an Mbed TLS repository.
+The results of the comparison are formatted as HTML and stored at
+a configurable location. Returns 0 on success, 1 on ABI/API non-compliance,
+and 2 if there is an error while running the script.
+Note: must be run from Mbed TLS root.

+#
+# This file is part of Mbed TLS (https://tls.mbed.org)
+#
+# Copyright (c) 2018, Arm Limited, All Rights Reserved
+#
+# Purpose
+#
+# Run a test using the debugger to check that the mbedtls_platform_zeroize()
+# function in platform_util.h is not being optimized out by the compiler. To do
+# so, the script loads the test program at programs/test/zeroize.c and sets a
+# breakpoint at the last return statement in main(). When the breakpoint is
+# hit, the debugger manually checks the contents to be zeroized and checks that
+# it is actually cleared.
+#
+# The mbedtls_platform_zeroize() test is debugger driven because there does not
+# seem to be a mechanism to reliably check whether the zeroize calls are being
+# eliminated by compiler optimizations from within the compiled program. The
+# problem is that a compiler would typically remove what it considers to be
+# "unecessary" assignments as part of redundant code elimination. To identify
+# such code, the compilar will create some form dependency graph between
+# reads and writes to variables (among other situations). It will then use this
+# data structure to remove redundant code that does not have an impact on the
+# program's observable behavior. In the case of mbedtls_platform_zeroize(), an
+# intelligent compiler could determine that this function clears a block of
+# memory that is not accessed later in the program, so removing the call to
+# mbedtls_platform_zeroize() does not have an observable behavior. However,
+# inserting a test after a call to mbedtls_platform_zeroize() to check whether
+# the block of memory was correctly zeroed would force the compiler to not
+# eliminate the mbedtls_platform_zeroize() call. If this does not occur, then
+# the compiler potentially has a bug.
+#
+# Note: This test requires that the test program is compiled with -g3.
+#
+# WARNING: There does not seem to be a mechanism in GDB scripts to set a
+# breakpoint at the end of a function (probably because there are a lot of
+# complications as function can have multiple exit points, etc). Therefore, it
+# was necessary to hard-code the line number of the breakpoint in the zeroize.c
+# test app. The assumption is that zeroize.c is a simple test app that does not
+# change often (as opposed to the actual library code), so the breakpoint line
+# number does not need to be updated often.
