Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ *) New function X509V3_add1_i2d(). This automatically encodes and
+ adds an extension. Its behaviour can be customised with various
+ flags to append, replace or delete. Various wrappers added for
+ certifcates and CRLs.
+ [Steve Henson]
+
+ *) Fix to avoid calling the underlying ASN1 print routine when
+ an extension cannot be parsed. Correct a typo in the
+ OCSP_SERVICELOC extension. Tidy up print OCSP format.
+ [Steve Henson]
+
+ *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
+ Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
+ when writing a 32767 byte record.
+ [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
+
+ *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
+ obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
+
+ (RSA objects have a reference count access to which is protected
+ by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
+ so they are meant to be shared between threads.)
+ [Bodo Moeller, Geoff Thorpe; original patch submitted by
+ "Reddie, Steven" <Steven.Reddie@ca.com>]
+
+ *) Make mkdef.pl parse some of the ASN1 macros and add apropriate
+ entries for variables.
+ [Steve Henson]
+
+ *) Fix a deadlock in CRYPTO_mem_leaks().
+ [Bodo Moeller]
+
+ *) Add functionality to apps/openssl.c for detecting locking
+ problems: As the program is single-threaded, all we have
+ to do is register a locking callback using an array for
+ storing which locks are currently held by the program.
+ [Bodo Moeller]
+
+ *) Use a lock around the call to CRYPTO_get_ex_new_index() in
+ SSL_get_ex_data_X509_STORE_idx(), which is used in
+ ssl_verify_cert_chain() and thus can be called at any time
+ during TLS/SSL handshakes so that thread-safety is essential.
+ Unfortunately, the ex_data design is not at all suited
+ for multi-threaded use, so it probably should be abolished.
+ [Bodo Moeller]
+
+ *) Added Broadcom "ubsec" ENGINE to OpenSSL.
+ [Broadcom, tweaked and integrated by Geoff Thorpe]
+
+ *) Move common extension printing code to new function
+ X509V3_print_extensions(). Reorganise OCSP print routines and
+ implement some needed OCSP ASN1 functions. Add OCSP extensions.
+ [Steve Henson]
+
+ *) New function X509_signature_print() to remove duplication in some
+ print routines.
+ [Steve Henson]
+
+ *) Add a special meaning when SET OF and SEQUENCE OF flags are both
+ set (this was treated exactly the same as SET OF previously). This
+ is used to reorder the STACK representing the structure to match the
+ encoding. This will be used to get round a problem where a PKCS7
+ structure which was signed could not be verified because the STACK
+ order did not reflect the encoded order.
+ [Steve Henson]
+
+ *) Reimplement the OCSP ASN1 module using the new code.
+ [Steve Henson]
+
+ *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
+ for its ASN1 operations. The old style function pointers still exist
+ for now but they will eventually go away.
+ [Steve Henson]
+
+ *) Merge in replacement ASN1 code from the ASN1 branch. This almost
+ completely replaces the old ASN1 functionality with a table driven
+ encoder and decoder which interprets an ASN1_ITEM structure describing
+ the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
+ largely maintained. Almost all of the old asn1_mac.h macro based ASN1
+ has also been converted to the new form.
+ [Steve Henson]
+
+ *) Change BN_mod_exp_recp so that negative moduli are tolerated
+ (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
+ so that BN_mod_exp_mont and BN_mod_exp_mont_word work
+ for negative moduli.
+ [Bodo Moeller]
+
+ *) Fix BN_uadd and BN_usub: Always return non-negative results instead
+ of not touching the result's sign bit.
+ [Bodo Moeller]
+
+ *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
+ set.
+ [Bodo Moeller]
+
*) Changed the LHASH code to use prototypes for callbacks, and created
macros to declare and implement thin (optionally static) functions
that provide type-safety and avoid function pointer casting for the
[Richard Levitte]
*) New function BN_mod_sqrt for computing square roots modulo a prime
- (Tonelli-Shanks algorithm unless p == 3 (mod 4) or p == 5 (mod 8)).
+ (using the probabilistic Tonelli-Shanks algorithm unless
+ p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
+ be handled deterministically).
[Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
*) Store verify_result within SSL_SESSION also for client side to
*) Disable ssl2_peek and ssl3_peek (i.e., both implementations
of SSL_peek) because they both are completely broken.
- They will be fixed RSN by adding an additional 'peek' parameter
- to the internal read functions.
+ For fixing this, the internal read functions now have an additional
+ 'peek' parameter, but the actual peek functionality has not
+ yet been implemented.
[Bodo Moeller]
*) New function BN_kronecker.
