     (found by Fabio Solari) (#256)
   * Fix bug in mbedtls_rsa_public() and mbedtls_rsa_private() that could
     result trying to unlock an unlocked mutex on invalid input (found by
     Fredrik Axelsson) (#257)
   * Fix -Wshadow warnings (found by hnrkp) (#240)
   * Fix unused function warning when using MBEDTLS_MDx_ALT or

   * The benchmark program also prints heap usage for public-key primitives
     if POLARSSL_MEMORY_BUFFER_ALLOC_C and POLARSSL_MEMORY_DEBUG are defined.
   * New script ecc-heap.sh helps measuring the impact of ECC parameters on
     speed and RAM (heap only for now) usage.
   * New script memory.sh helps measuring the ROM and RAM requirements of two
     reduced configurations (PSK-CCM and NSA suite B).
   * Add config flag POLARSSL_DEPRECATED_WARNING (off by default) to produce
     warnings on use of deprecated functions (with GCC and Clang only).

     errors on use of deprecated functions.

Bugfix
   * Fix compile errors with PLATFORM_NO_STD_FUNCTIONS.
   * Fix compile error with PLATFORM_EXIT_ALT (thanks to Rafał Przywara).
   * Fix bug in entropy.c when THREADING_C is also enabled that caused

   * Fix memory leak when gcm_setkey() and ccm_setkey() are used more than
     once on the same context.
   * Fix bug in ssl_mail_client when password is longer that username (found

     doing it at runtime (using uname) rather that compile time.
   * Fix handling of symlinks by "make install" (found by Gaël PORTAY).
   * Fix potential NULL pointer dereference (not trigerrable remotely) when
     ssl_write() is called before the handshake is finished (introduced in
     1.3.10) (first reported by Martin Blumenstingl).
   * Fix bug in pk_parse_key() that caused some valid private EC keys to be
     rejected.
   * Fix bug in Via Padlock support (found by Nikos Mavrogiannopoulos).
   * Fix thread safety bug in RSA operations (found by Fredrik Axelsson).
   * Fix hardclock() (only used in the benchmarking program) with some
     versions of mingw64 (found by kxjhlele).

   * Add missing dependency on SHA-256 in some x509 programs (reported by
     Gergely Budai).
   * Fix bug related to ssl_set_curves(): the client didn't check that the
     curve picked by the server was actually allowed.

Changes
   * Remove bias in mpi_gen_prime (contributed by Pascal Junod).
   * Remove potential sources of timing variations (some contributed by Pascal
     Junod).
   * Options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 are deprecated.
   * Enabling POLARSSL_NET_C without POLARSSL_HAVE_IPV6 is deprecated.
   * compat-1.2.h and openssl.h are deprecated.
   * Adjusting/overriding CFLAGS and LDFLAGS with the make build system is now
     more flexible (warning: OFLAGS is not used any more) (see the README)
     (contributed by Alon Bar-Lev).
   * ssl_set_own_cert() no longer calls pk_check_pair() since the
     performance impact was bad for some users (this was introduced in 1.3.10).
   * Move from SHA-1 to SHA-256 in example programs using signatures
     (suggested by Thorsten Mühlfelder).
   * Remove some unneeded inclusions of header files from the standard library
     "minimize" others (eg use stddef.h if only size_t is needed).
   * Change #include lines in test files to use double quotes instead of angle
     brackets for uniformity with the rest of the code.
   * Remove dependency on sscanf() in X.509 parsing modules.

= mbed TLS 1.3.10 released 2015-02-09
Security
   * NULL pointer dereference in the buffer-based allocator when the buffer is
     full and polarssl_free() is called (found by Mark Hasemeyer)
     (only possible if POLARSSL_MEMORY_BUFFER_ALLOC_C is enabled, which it is
     not by default).
   * Fix remotely-triggerable uninitialised pointer dereference caused by
     crafted X.509 certificate (TLS server is not affected if it doesn't ask for a
     client certificate) (found using Codenomicon Defensics).
   * Fix remotely-triggerable memory leak caused by crafted X.509 certificates
     (TLS server is not affected if it doesn't ask for a client certificate)
     (found using Codenomicon Defensics).

     (TLS server is not affected if it doesn't ask for a client certificate)
     (found using Codenomicon Defensics).
   * Fix timing difference that could theoretically lead to a
     Bleichenbacher-style attack in the RSA and RSA-PSK key exchanges
     (reported by Sebastian Schinzel).

     length of an X.509 verification chain.
   * Support for renegotiation can now be disabled at compile-time
   * Support for 1/n-1 record splitting, a countermeasure against BEAST.
   * Certificate selection based on signature hash, preferring SHA-1 over SHA-2
     for pre-1.2 clients when multiple certificates are available.
   * Add support for getrandom() syscall on recent Linux kernels with Glibc or
     a compatible enough libc (eg uClibc).
   * Add ssl_set_arc4_support() to make it easier to disable RC4 at runtime
     while using the default ciphersuite list.
   * Added new error codes and debug messages about selection of
     ciphersuite/certificate.

Bugfix
   * Stack buffer overflow if ctr_drbg_update() is called with too large
     add_len (found by Jean-Philippe Aumasson) (not triggerable remotely).
   * Possible buffer overflow of length at most POLARSSL_MEMORY_ALIGN_MULTIPLE
     if memory_buffer_alloc_init() was called with buf not aligned and len not
     a multiple of POLARSSL_MEMORY_ALIGN_MULTIPLE (not triggerable remotely).
   * User set CFLAGS were ignored by Cmake with gcc (introduced in 1.3.9, found
     by Julian Ospald).

     Peter Vaskovic).
   * Fix assembly selection for MIPS64 (thanks to James Cowgill).
   * ssl_get_verify_result() now works even if the handshake was aborted due
     to a failed verification (found by Fredrik Axelsson).
   * Skip writing and parsing signature_algorithm extension if none of the
     key exchanges enabled needs certificates. This fixes a possible interop
     issue with some servers when a zero-length extension was sent. (Reported
     by Peter Dettman.)
   * On a 0-length input, base64_encode() did not correctly set output length
     (found by Hendrik van den Boogaard).

Changes
   * Use deterministic nonces for AEAD ciphers in TLS by default (possible to
     switch back to random with POLARSSL_SSL_AEAD_RANDOM_IV in config.h).
   * Blind RSA private operations even when POLARSSL_RSA_NO_CRT is defined.
   * ssl_set_own_cert() now returns an error on key-certificate mismatch.
   * Forbid repeated extensions in X.509 certificates.
   * debug_print_buf() now prints a text view in addition to hexadecimal.
   * A specific error is now returned when there are ciphersuites in common
     but none of them is usable due to external factors such as no certificate
     with a suitable (extended)KeyUsage or curve or no PSK set.
   * It is now possible to disable negotiation of truncated HMAC server-side
     at runtime with ssl_set_truncated_hmac().
   * Example programs for SSL client and server now disable SSLv3 by default.
   * Example programs for SSL client and server now disable RC4 by default.
   * Use platform.h in all test suites and programs.

= PolarSSL 1.3.9 released 2014-10-20
Security
   * Lowest common hash was selected from signature_algorithms extension in
     TLS 1.2 (found by Darren Bane) (introduced in 1.3.8).

     (server is not affected if it doesn't ask for a client certificate)
     (found using Codenomicon Defensics).
   * Remotely-triggerable memory leak when parsing crafted ClientHello
     (not affected if ECC support was compiled out) (found using Codenomicon

     are defined but not POLARSSL_HAVE_TIME (found by Stephane Di Vito).
   * Remove non-existent file from VS projects (found by Peter Vaskovic).
   * ssl_read() could return non-application data records on server while
     renegotation was pending, and on client when a HelloRequest was received.
   * Server-initiated renegotiation would fail with non-blocking I/O if the
     write callback returned WANT_WRITE when requesting renegotiation.
   * ssl_close_notify() could send more than one message in some circumstances
     with non-blocking I/O.
   * Fix compiler warnings on iOS (found by Sander Niemeijer).
   * x509_crt_parse() did not increase total_failed on PEM error
   * Fix compile error with armcc in mpi_is_prime()
   * Fix potential bad read in parsing ServerHello (found by Adrien
     Vialletelle).

Changes
   * Ciphersuites using SHA-256 or SHA-384 now require TLS 1.x (there is no
     standard defining how to use SHA-2 with SSL 3.0).
   * Ciphersuites using RSA-PSK key exchange new require TLS 1.x (the spec is
     ambiguous on how to encode some packets with SSL 3.0).
   * Made buffer size in pk_write_(pub)key_pem() more dynamic, eg smaller if
     RSA is disabled, larger if POLARSSL_MPI_MAX_SIZE is larger.
   * ssl_read() now returns POLARSSL_ERR_NET_WANT_READ rather than
     POLARSSL_ERR_SSL_UNEXPECTED_MESSAGE on harmless alerts.
   * POLARSSL_MPI_MAX_SIZE now defaults to 1024 in order to allow 8192 bits
     RSA keys.
   * Accept spaces at end of line or end of buffer in base64_decode().
   * X.509 certificates with more than one AttributeTypeAndValue per
     RelativeDistinguishedName are not accepted any more.

= PolarSSL 1.3.8 released 2014-07-11
Security
   * Fix length checking for AEAD ciphersuites (found by Codenomicon).

   * Support for CCM and CCM_8 ciphersuites
   * Support for parsing and verifying RSASSA-PSS signatures in the X.509

   * Add example config.h for PSK with CCM, optimized for low RAM usage.
   * Optimize for RAM usage in example config.h for NSA Suite B profile.
   * Add POLARSSL_REMOVE_ARC4_CIPHERSUITES to allow removing RC4 ciphersuites
     from the default list (inactive by default).
   * Add server-side enforcement of sent renegotiation requests
     (ssl_set_renegotiation_enforced())
   * Add SSL_CIPHERSUITES config.h flag to allow specifying a list of
     ciphersuites to use and save some memory if the list is small.

Changes
   * Add LINK_WITH_PTHREAD option in CMake for explicit linking that is
     required on some platforms (e.g. OpenBSD)
   * Migrate zeroizing of data to polarssl_zeroize() instead of memset()
     against unwanted compiler optimizations
   * md_list() now returns hashes strongest first

   * Very small records were incorrectly rejected when truncated HMAC was in
     use with some ciphersuites and versions (RC4 in all versions, CBC with
     versions < TLS 1.1).
   * Very large records using more than 224 bytes of padding were incorrectly
     rejected with CBC-based ciphersuites and TLS >= 1.1
   * Very large records using less padding could cause a buffer overread of up
     to 32 bytes with CBC-based ciphersuites and TLS >= 1.1
   * Restore ability to use a v1 cert as a CA if trusted locally. (This had
     been removed in 1.3.6.)
   * Restore ability to locally trust a self-signed cert that is not a proper
     CA for use as an end entity certificate. (This had been removed in
     1.3.6.)
   * Fix preprocessor checks for bn_mul PPC asm (found by Barry K. Nathan).
   * Use \n\t rather than semicolons for bn_mul asm, since some assemblers
     interpret semicolons as comment delimiters (found by Barry K. Nathan).
   * Fix off-by-one error in parsing Supported Point Format extension that
     caused some handshakes to fail.
   * Fix possible miscomputation of the premaster secret with DHE-PSK key
     exchange that caused some handshakes to fail with other implementations.
     (Failure rate <= 1/255 with common DHM moduli.)
   * Disable broken Sparc64 bn_mul assembly (found by Florian Obser).
   * Fix base64_decode() to return and check length correctly (in case of
     tight buffers)
   * Fix mpi_write_string() to write "00" as hex output for empty MPI (found

     checked and filled in the relevant module headers
   * Debug module only outputs full lines instead of parts
   * Better support for the different Attribute Types from IETF PKIX (RFC 5280)
   * AES-NI now compiles with "old" assemblers too

   * Add option 'use_dev_random' to gen_key application
   * Enable verification of the keyUsage extension for CA and leaf
     certificates (POLARSSL_X509_CHECK_KEY_USAGE)
   * Enable verification of the extendedKeyUsage extension
     (POLARSSL_X509_CHECK_EXTENDED_KEY_USAGE)

Changes
   * x509_crt_info() now prints information about parsed extensions as well
   * pk_verify() now returns a specific error code when the signature is valid

   * Reject certificates with times not in UTC, per RFC 5280.

Security
   * Avoid potential timing leak in ecdsa_sign() by blinding modular division.
     (Found by Watson Ladd.)
   * The notAfter date of some certificates was no longer checked since 1.3.5.
     This affects certificates in the user-supplied chain except the top
     certificate. If the user-supplied chain contains only one certificates,
     it is not affected (ie, its notAfter date is properly checked).
   * Prevent potential NULL pointer dereference in ssl_read_record() (found by
     TrustInSoft)

Bugfix
   * The length of various ClientKeyExchange messages was not properly checked.

   * oid_get_numeric_string() used to truncate the output without returning an
     error if the output buffer was just 1 byte too small.
   * dhm_parse_dhm() (hence dhm_parse_dhmfile()) did not set dhm->len.
   * Calling pk_debug() on an RSA-alt key would segfault.
   * pk_get_size() and pk_get_len() were off by a factor 8 for RSA-alt keys.
   * Potential buffer overwrite in pem_write_buffer() because of low length
     indication (found by Thijs Alkemade)
   * EC curves constants, which should be only in ROM since 1.3.3, were also
     stored in RAM due to missing 'const's (found by Gergely Budai).

     testing against GnuTLS
   * Deprecated ssl_set_own_cert_rsa() and ssl_set_own_cert_rsa_alt()
   * Improvements to tests/Makefile, contributed by Oden Eriksson.

Security
   * Forbid change of server certificate during renegotiation to prevent
     "triple handshake" attack when authentication mode is 'optional' (the
     attack was already impossible when authentication is required).
   * Check notBefore timestamp of certificates and CRLs from the future.
   * Forbid sequence number wrapping
   * Fixed possible buffer overflow with overlong PSK
   * Possible remotely-triggered out-of-bounds memory access fixed (found by

     client certificate.
   * ssl_srv was leaking memory when client presented a timed out ticket
     containing a client certificate
   * ssl_init() was leaving a dirty pointer in ssl_context if malloc of

Features
   * Added ssl_session_reset() to allow better multi-connection pools of
     SSL contexts without needing to set all non-connection-specific
	 data and pointers again. Adapted ssl_server to use this functionality.
   * Added ssl_set_max_version() to allow clients to offer a lower maximum

     a consequence in library code and programs
   * Moved all examples programs to use the new entropy and CTR_DRBG
   * Added permissive certificate parsing to x509parse_crt() and
     x509parse_crtfile(). With permissive parsing the parsing does not stop on
     encountering a parse-error. Beware that the meaning of return values has
     changed!
   * All error codes are now negative. Even on mermory failures and IO errors.

Bugfix
   * Fixed faulty HMAC-MD2 implementation. Found by dibac. (Closes
     ticket #37)
   * Fixed a bug where the CRL parser expected an EXPLICIT ASN.1 tag
     before version numbers
   * Allowed X509 key usage parsing to accept 4 byte values instead of the
     standard 1 byte version sometimes used by Microsoft. (Closes ticket #38)
   * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
     smaller than the hash length. (Closes ticket #41)

     appended with '....' after first 28 octets
   * Improved build support for s390x and sparc64 in bignum.h

     (AES CTR, Camellia CTR, XTEA CBC) including the option to
     enable and disable individual modes when needed
   * Functions requiring File System functions can now be disabled
     by undefining POLARSSL_FS_IO
   * A error_strerror function() has been added to translate between
     error codes and their description.
   * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
     functions.
   * Added ssl_mail_client and ssl_fork_server as example programs.

Changes
   * Major argument / variable rewrite. Introduced use of size_t
     instead of int for buffer lengths and loop variables for
     better unsigned / signed use. Renamed internal bigint types
     t_int and t_dbl to t_uint and t_udbl in the process
   * mpi_init() and mpi_free() now only accept a single MPI
     argument and do not accept variable argument lists anymore.
   * The error codes have been remapped and combining error codes
     is now done with a PLUS instead of an OR as error codes
     used are negative.
   * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
     net_recv() now returns 0 on EOF instead of
     POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
     POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
     ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
     after the handshake.
   * Network functions now return POLARSSL_ERR_NET_WANT_READ or
     POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
     POLARSSL_ERR_NET_TRY_AGAIN

= Version 0.99-pre4 released on 2011-04-01

     functionality as well.
   * Added mpi_fill_random() for centralized filling of big numbers
     with random data (Fixed ticket #10)

Changes
   * Debug print of MPI now removes leading zero octets and 
     displays actual bit size of the value.
   * x509parse_key() (and as a consequence x509parse_keyfile()) 
     does not zeroize memory in advance anymore. Use rsa_init()
     before parsing a key or keyfile!

Bugfix
   * Debug output of MPI's now the same independent of underlying
     platform (32-bit / 64-bit) (Fixes ticket #19, found by Mads
     Kiilerich and Mihai Militaru)
   * Fixed bug in ssl_write() when flushing old data (Fixed ticket
     #18, found by Nikolay Epifanov)
