It is similar to -WWW, but requires + that the file contains a complete HTTP response. + [Richard Levitte] + + *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl + change the def and num file printf format specifier from "%-40sXXX" + to "%-39s XXX". The latter will always guarantee a space after the + field while the former will cause them to run together if the field + is 40 of more characters long. + [Steve Henson] + + *) Constify the cipher and digest 'method' functions and structures + and modify related functions to take constant EVP_MD and EVP_CIPHER + pointers. + [Steve Henson] + + *) Implement ssl23_peek (analogous to ssl23_read), which previously + did not exist. + [Bodo Moeller] + + *) Replace rdtsc with _emit statements for VC++ version 5. + [Jeremy Cooper ] + + *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them + in . Also further increase BN_CTX_NUM to 24. + [Bodo Moeller] + + *) Modify EVP_Digest*() routines so they now return values. Although the + internal software routines can never fail additional hardware versions + might. + [Steve Henson] + + *) Clean up crypto/err/err.h and change some error codes to avoid conflicts: + + Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 + (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. + + ASN1 error codes + ERR_R_NESTED_ASN1_ERROR + ... + ERR_R_MISSING_ASN1_EOS + were 4 .. 9, conflicting with + ERR_LIB_RSA (= ERR_R_RSA_LIB) + ... + ERR_LIB_PEM (= ERR_R_PEM_LIB). + They are now 58 .. 63 (i.e., just below ERR_R_FATAL). + + Add new error code 'ERR_R_INTERNAL_ERROR'. + [Bodo Moeller] + + *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock + suffices. + [Bodo Moeller] + + *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This + sets the subject name for a new request or supersedes the + subject name in a given request. Formats that can be parsed are + 'CN=Some Name, OU=myOU, C=IT' + and + 'CN=Some Name/OU=myOU/C=IT'. + + Add options '-batch' and '-verbose' to 'openssl req'. + [Massimiliano Pala ] + + *) Make it possible to reuse SSLv2 sessions. + [Richard Levitte] + + *) Introduce the possibility to access global variables through + functions on platform were that's the best way to handle exporting + global variables in shared libraries. To enable this functionality, + one must configure with "EXPORT_VAR_AS_FN" or defined the C macro + "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter + is normally done by Configure or something similar). + + To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL + in the source file (foo.c) like this: + + OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; + OPENSSL_IMPLEMENT_GLOBAL(double,bar); + + To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL + and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: + + OPENSSL_DECLARE_GLOBAL(int,foo); + #define foo OPENSSL_GLOBAL_REF(foo) + OPENSSL_DECLARE_GLOBAL(double,bar); + #define bar OPENSSL_GLOBAL_REF(bar) + + The #defines are very important, and therefore so is including the + header file everywere where the defined globals are used. + + The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition + of ASN.1 items, but that structure is a bt different. + + The largest change is in util/mkdef.pl which has been enhanced with + better and easier to understand logic to choose which symbols should + go into the Windows .def files as well as a number of fixes and code + cleanup (among others, algorithm keywords are now sorted + lexicographically to avoid constant rewrites). + [Richard Levitte] + + *) In copy_email() check for >= 0 as a return value for + X509_NAME_get_index_by_NID() since 0 is a valid index. + [Steve Henson reported by Massimiliano Pala ] + + *) In BN_div() keep a copy of the sign of 'num' before writing the + result to 'rm' because if rm==num the value will be overwritten + and produce the wrong result if 'num' is negative: this caused + problems with BN_mod() and BN_nnmod(). + [Steve Henson] + + *) Function OCSP_request_verify(). This checks the signature on an + OCSP request and verifies the signer certificate. The signer + certificate is just checked for a generic purpose and OCSP request + trust settings. + [Steve Henson] + + *) Add OCSP_check_validity() function to check the validity of OCSP + responses. OCSP responses are prepared in real time and may only + be a few seconds old. Simply checking that the current time lies + between thisUpdate and nextUpdate max reject otherwise valid responses + caused by either OCSP responder or client clock innacuracy. Instead + we allow thisUpdate and nextUpdate to fall within a certain period of + the current time. The age of the response can also optionally be + checked. Two new options -validity_period and -status_age added to + ocsp utility. + [Steve Henson] + + *) If signature or public key algorithm is unrecognized print out its + OID rather that just UNKOWN. + [Steve Henson] + + *) Avoid coredump with unsupported or invalid public keys by checking if + X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when + PKCS7_verify() fails with non detached data. + [Steve Henson] + + *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and + OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate + ID to be generated from the issuer certificate alone which can then be + passed to OCSP_id_issuer_cmp(). + [Steve Henson] + + *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new + ASN1 modules to export functions returning ASN1_ITEM pointers + instead of the ASN1_ITEM structures themselves. This adds several + new macros which allow the underlying ASN1 function/structure to + be accessed transparently. As a result code should not use ASN1_ITEM + references directly (such as &X509_it) but instead use the relevant + macros (such as ASN1_ITEM_rptr(X509)). This option is to allow + use of the new ASN1 code on platforms where exporting structures + is problematical (for example in shared libraries) but exporting + functions returning pointers to structures is not. + [Steve Henson] + + *) Add support for overriding the generation of SSL/TLS session IDs. + These callbacks can be registered either in an SSL_CTX or per SSL. + The purpose of this is to allow applications to control, if they wish, + the arbitrary values chosen for use as session IDs, particularly as it + can be useful for session caching in multiple-server environments. A + command-line switch for testing this (and any client code that wishes + to use such a feature) has been added to "s_server". + [Geoff Thorpe, Lutz Jaenicke] + + *) Modify mkdef.pl to recognise and parse prprocessor conditionals + of the form '#if defined(...) || defined(...) || ...' and + '#if !defined(...) && !defined(...) && ...'. This also avoids + the growing number of special cases it was previously handling. + [Richard Levitte] + + *) Don't use getenv in library functions when run as setuid/setgid. + New function OPENSSL_issetugid(). + [Ulf Moeller] + + *) Make all configuration macros available for application by making + sure they are available in opensslconf.h, by giving them names starting + with "OPENSSL_" to avoid conflicts with other packages and by making + sure e_os2.h will cover all platform-specific cases together with + opensslconf.h. + Additionally, it is now possible to define configuration/platform- + specific names (called "system identities"). In the C code, these + are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another + macro with the name beginning with "OPENSSL_SYS_", which is determined + from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on + what is available. + [Richard Levitte] + + *) New option -set_serial to 'req' and 'x509' this allows the serial + number to use to be specified on the command line. Previously self + signed certificates were hard coded with serial number 0 and the + CA options of 'x509' had to use a serial number in a file which was + auto incremented. + [Steve Henson] + + *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c) + due to incorrect handling of multi-threading: + + 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl(). + + 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on(). + + 3. Count how many times MemCheck_off() has been called so that + nested use can be treated correctly. This also avoids + inband-signalling in the previous code (which relied on the + assumption that thread ID 0 is impossible). + [Bodo Moeller] + + *) New options to 'ca' utility to support V2 CRL entry extensions. + Currently CRL reason, invalidity date and hold instruction are + supported. Add new CRL extensions to V3 code and some new objects. + [Steve Henson] + *) Add "-rand" option also to s_client and s_server. [Lutz Jaenicke] @@ -71,6 +283,9 @@ *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent Bleichenbacher's DSA attack. + Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits + to be set and top=0 forces the highest bit to be set; top=-1 is new + and leaves the highest bit random.
