Two new + ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN + uses the special reorder version of SET OF to sort the attributes + and reorder them to match the encoded order. This resolves a long + standing problem: a verify on a PKCS7 structure just after signing + it used to fail because the attribute order did not match the + encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: + it uses the received order. This is necessary to tolerate some broken + software that does not order SET OF. This is handled by encoding + as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) + to produce the required SET OF. + [Steve Henson] + + *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and + OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header + files to get correct declarations of the ASN.1 item variables. + [Richard Levitte] + + *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many + PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: + asn1_check_tlen() would sometimes attempt to use 'ctx' when it was + NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). + New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant + ASN1_ITEM and no wrapper functions. + [Steve Henson] + + *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These + replace the old function pointer based I/O routines. Change most of + the *_d2i_bio() and *_d2i_fp() functions to use these. + [Steve Henson] + + *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor + lines, recognice more "algorithms" that can be deselected, and make + it complain about algorithm deselection that isn't recognised. + [Richard Levitte] + + *) New ASN1 functions to handle dup, sign, verify, digest, pack and + unpack operations in terms of ASN1_ITEM. Modify existing wrappers + to use new functions. Add NO_ASN1_OLD which can be set to remove + some old style ASN1 functions: this can be used to determine if old + code will still work when these eventually go away. + [Steve Henson] + + *) New extension functions for OCSP structures, these follow the + same conventions as certificates and CRLs. + [Steve Henson] + + *) 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 ] + + *) 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.
