OpenSSL CHANGES
_______________
- Changes between 0.9.8g and 0.9.9 [xx XXX xxxx]
+ Changes between 0.9.8i and 0.9.9 [xx XXX xxxx]
+
+ *) Add support for policy mappings extension.
+
+ This work was sponsored by Google.
+ [Steve Henson]
+
+ *) Fixes to pathlength constraint, self issued certificate handling,
+ policy processing to align with RFC3280 and PKITS tests.
+
+ This work was sponsored by Google.
+ [Steve Henson]
+
+ *) Support for name constraints certificate extension. DN, email, DNS
+ and URI types are currently supported.
+
+ This work was sponsored by Google.
+ [Steve Henson]
+
+ *) To cater for systems that provide a pointer-based thread ID rather
+ than numeric, deprecate the current numeric thread ID mechanism and
+ replace it with a structure and associated callback type. This
+ mechanism allows a numeric "hash" to be extracted from a thread ID in
+ either case, and on platforms where pointers are larger than 'long',
+ mixing is done to help ensure the numeric 'hash' is usable even if it
+ can't be guaranteed unique. The default mechanism is to use "&errno"
+ as a pointer-based thread ID to distinguish between threads.
+
+ Applications that want to provide their own thread IDs should now use
+ CRYPTO_THREADID_set_callback() to register a callback that will call
+ either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer().
+
+ (This new approach replaces the functions CRYPTO_set_idptr_callback(),
+ CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in
+ OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an
+ application was previously providing a numeric thread callback that
+ was inappropriate for distinguishing threads, then uniqueness might
+ have been obtained with &errno that happened immediately in the
+ intermediate development versions of OpenSSL; this is no longer the
+ case, the numeric thread callback will now override the automatic use
+ of &errno.)
+ [Geoff Thorpe, with help from Bodo Moeller]
+
+ *) Initial support for different CRL issuing certificates. This covers a
+ simple case where the self issued certificates in the chain exist and
+ the real CRL issuer is higher in the existing chain.
+
+ This work was sponsored by Google.
+ [Steve Henson]
+
+ *) Removed effectively defunct crypto/store from the build.
+ [Ben Laurie]
+
+ *) Revamp of STACK to provide stronger type-checking. Still to come:
+ TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE,
+ ASN1_STRING, CONF_VALUE.
+ [Ben Laurie]
+
+ *) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer
+ RAM on SSL connections. This option can save about 34k per idle SSL.
+ [Nick Mathewson]
+
+ *) Revamp of LHASH to provide stronger type-checking. Still to come:
+ STACK, TXT_DB, bsearch, qsort.
+ [Ben Laurie]
+
+ *) Initial support for Cryptographic Message Syntax (aka CMS) based
+ on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility,
+ support for data, signedData, compressedData, digestedData and
+ encryptedData, envelopedData types included. Scripts to check against
+ RFC4134 examples draft and interop and consistency checks of many
+ content types and variants.
+ [Steve Henson]
+
+ *) Add options to enc utility to support use of zlib compression BIO.
+ [Steve Henson]
+
+ *) Extend mk1mf to support importing of options and assembly language
+ files from Configure script, currently only included in VC-WIN32.
+ The assembly language rules can now optionally generate the source
+ files from the associated perl scripts.
+ [Steve Henson]
+
+ *) Implement remaining functionality needed to support GOST ciphersuites.
+ Interop testing has been performed using CryptoPro implementations.
+ [Victor B. Wagner <vitus@cryptocom.ru>]
*) s390x assembler pack.

- *) In addition to the numerical (unsigned long) thread ID, provide
- for a pointer (void *) thread ID. This helps accomodate systems
- that do not provide an unsigned long thread ID. OpenSSL assumes
- it is in the same thread iff both the numerical and the pointer
- thread ID agree; so applications are just required to define one
- of them appropriately (e.g., by using a pointer to a per-thread
- memory object malloc()ed by the application for the pointer-type
- thread ID). Exactly analoguous to the existing functions
-
- void CRYPTO_set_id_callback(unsigned long (*func)(void));
- unsigned long (*CRYPTO_get_id_callback(void))(void);
- unsigned long CRYPTO_thread_id(void);
-
- we now have additional functions
-
- void CRYPTO_set_idptr_callback(void *(*func)(void));
- void *(*CRYPTO_get_idptr_callback(void))(void);
- void *CRYPTO_thread_idptr(void);
-
- also in <openssl/crypto.h>. The default value for
- CRYPTO_thread_idptr() if the application has not provided its own
- callback is &errno.
- [Bodo Moeller]
-
*) Change the array representation of binary polynomials: the list
of degrees of non-zero coefficients is now terminated with -1.
Previously it was terminated with 0, which was also part of the
*) Change 'Configure' script to enable Camellia by default.
[NTT]
- Changes between 0.9.8g and 0.9.8h [xx XXX xxxx]
+ Changes between 0.9.8h and 0.9.8i [xx XXX xxxx]
+
+ *) Add support for Local Machine Keyset attribute in PKCS#12 files.
+ [Steve Henson]
+
+ *) Fix BN_GF2m_mod_arr() top-bit cleanup code.
+ [Huang Ying]
+
+ *) Expand ENGINE to support engine supplied SSL client certificate functions.
+
+ This work was sponsored by Logica.
+ [Steve Henson]
+
+ *) Add CryptoAPI ENGINE to support use of RSA and DSA keys held in Windows
+ keystores. Support for SSL/TLS client authentication too.
+ Not compiled unless enable-capieng specified to Configure.
+
+ This work was sponsored by Logica.
+ [Steve Henson]
+
+ Changes between 0.9.8g and 0.9.8h [28 May 2008]
+
+ *) Fix flaw if 'Server Key exchange message' is omitted from a TLS
+ handshake which could lead to a cilent crash as found using the
+ Codenomicon TLS test suite (CVE-2008-1672)
+ [Steve Henson, Mark Cox]
+
+ *) Fix double free in TLS server name extensions which could lead to
+ a remote crash found by Codenomicon TLS test suite (CVE-2008-0891)
+ [Joe Orton]
+
+ *) Clear error queue in SSL_CTX_use_certificate_chain_file()
+
+ Clear the error queue to ensure that error entries left from
+ older function calls do not interfere with the correct operation.
+ [Lutz Jaenicke, Erik de Castro Lopo]
+
+ *) Remove root CA certificates of commercial CAs:
+
+ The OpenSSL project does not recommend any specific CA and does not
+ have any policy with respect to including or excluding any CA.
+ Therefore it does not make any sense to ship an arbitrary selection
+ of root CA certificates with the OpenSSL software.
+ [Lutz Jaenicke]
+
+ *) RSA OAEP patches to fix two separate invalid memory reads.
+ The first one involves inputs when 'lzero' is greater than
+ 'SHA_DIGEST_LENGTH' (it would read about SHA_DIGEST_LENGTH bytes
+ before the beginning of from). The second one involves inputs where
+ the 'db' section contains nothing but zeroes (there is a one-byte
+ invalid read after the end of 'db').
+ [Ivan Nestlerode <inestlerode@us.ibm.com>]
+
+ *) Add TLS session ticket callback. This allows an application to set
+ TLS ticket cipher and HMAC keys rather than relying on hardcoded fixed
+ values. This is useful for key rollover for example where several key
+ sets may exist with different names.
+ [Steve Henson]
+
+ *) Reverse ENGINE-internal logic for caching default ENGINE handles.
+ This was broken until now in 0.9.8 releases, such that the only way
+ a registered ENGINE could be used (assuming it initialises
+ successfully on the host) was to explicitly set it as the default
+ for the relevant algorithms. This is in contradiction with 0.9.7
+ behaviour and the documentation. With this fix, when an ENGINE is
+ registered into a given algorithm's table of implementations, the
+ 'uptodate' flag is reset so that auto-discovery will be used next
+ time a new context for that algorithm attempts to select an
+ implementation.
+ [Ian Lister (tweaked by Geoff Thorpe)]
+
+ *) Update the GMP engine glue to do direct copies between BIGNUM and
+ mpz_t when openssl and GMP use the same limb size. Otherwise the
+ existing "conversion via a text string export" trick is still used.
+ [Paul Sheer <paulsheer@gmail.com>, Geoff Thorpe]
+
+ *) Zlib compression BIO. This is a filter BIO which compressed and
+ uncompresses any data passed through it.
+ [Steve Henson]
+
+ *) Add AES_wrap_key() and AES_unwrap_key() functions to implement
+ RFC3394 compatible AES key wrapping.
+ [Steve Henson]
+
+ *) Add utility functions to handle ASN1 structures. ASN1_STRING_set0():
+ sets string data without copying. X509_ALGOR_set0() and
+ X509_ALGOR_get0(): set and retrieve X509_ALGOR (AlgorithmIdentifier)
+ data. Attribute function X509at_get0_data_by_OBJ(): retrieves data
+ from an X509_ATTRIBUTE structure optionally checking it occurs only
+ once. ASN1_TYPE_set1(): set and ASN1_TYPE structure copying supplied
+ data.
+ [Steve Henson]
+
+ *) Fix BN flag handling in RSA_eay_mod_exp() and BN_MONT_CTX_set()
+ to get the expected BN_FLG_CONSTTIME behavior.
+ [Bodo Moeller (Google)]
+
+ *) Netware support:
+
+ - fixed wrong usage of ioctlsocket() when build for LIBC BSD sockets
+ - fixed do_tests.pl to run the test suite with CLIB builds too (CLIB_OPT)
+ - added some more tests to do_tests.pl
+ - fixed RunningProcess usage so that it works with newer LIBC NDKs too
+ - removed usage of BN_LLONG for CLIB builds to avoid runtime dependency
+ - added new Configure targets netware-clib-bsdsock, netware-clib-gcc,
+ netware-clib-bsdsock-gcc, netware-libc-bsdsock-gcc
+ - various changes to netware.pl to enable gcc-cross builds on Win32
+ platform
+ - changed crypto/bio/b_sock.c to work with macro functions (CLIB BSD)
+ - various changes to fix missing prototype warnings
+ - fixed x86nasm.pl to create correct asm files for NASM COFF output
+ - added AES, WHIRLPOOL and CPUID assembler code to build files
+ - added missing AES assembler make rules to mk1mf.pl
+ - fixed order of includes in apps/ocsp.c so that e_os.h settings apply
+ [Guenter Knauf <eflash@gmx.net>]
*) Implement certificate status request TLS extension defined in RFC3546.
A client can set the appropriate parameters and receive the encoded
