+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.

 mbed TLS ChangeLog (Sorted per branch, date)
 
-= mbed TLS 2.7.x branch released 2018-xx-xx
+= 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.

+ *      - mbedtls_rsa_deduce_private_exponent

+ *                 does not imply that a subsequent call to
+ *                 \c mbedtls_ssl_read will provide any data;

+ *                 If the SSL/TLS module successfully returns from an
+ *                 operation - e.g. a handshake or an application record

+ *                 must not immediately idle on the underlying transport
+ *                 to have data ready, but you need to check the value
+ *                 of this function first. The reason is that the desired
+ *                 data might already be read but not yet processed.
+ *                 If, in contrast, a previous call to the SSL/TLS module

+ *                   initially available on the underlying transport, as this data may have
+ *                   been only e.g. duplicated messages or a renegotiation request.
+ *                   Therefore, you must be prepared to receive MBEDTLS_ERR_SSL_WANT_READ even
+ *                   when reacting to an incoming-data event from the underlying transport.
+ *                 - On success, the datagram of the underlying transport that is currently

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

+ * 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)
