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 ] + + *) 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" ] + + *) 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 + type-specific callbacks. + [Geoff Thorpe] + + *) Use better test patterns in bntest. + [Ulf Möller] + + *) Added Kerberos Cipher Suites to be used with TLS, as written in + RFC 2712. + [Veers Staats , + Jeffrey Altman , via Richard Levitte] + + *) rand_win.c fix for Borland C. + [Ulf Möller] + + *) BN_rshift bugfix for n == 0. + [Bodo Moeller] + + *) Reformat the FAQ so the different questions and answers can be divided + in sections depending on the subject. + [Richard Levitte] + + *) Have the zlib compression code load ZLIB.DLL dynamically under + Windows. + [Richard Levitte] + + *) New function BN_mod_sqrt for computing square roots modulo a prime + (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 , Bodo Moeller] + *) Store verify_result within SSL_SESSION also for client side to avoid potential security hole.
