Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ *) Add a 'copy_extensions' option to the 'ca' utility. This copies
+ extensions from a certificate request to the certificate.
+ [Steve Henson]
+
+ *) Allow multiple 'certopt' and 'nameopt' options to be separated
+ by commas. Add 'namopt' and 'certopt' options to the 'ca' config
+ file: this allows the display of the certificate about to be
+ signed to be customised, to allow certain fields to be included
+ or excluded and extension details. The old system didn't display
+ multicharacter strings properly, omitted fields not in the policy
+ and couldn't display additional details such as extensions.
+ [Steve Henson]
+
+ *) Fix memory leaks in err.c: free err_data string if necessary;
+ don't write to the wrong index in ERR_set_error_data.
+ [Bodo Moeller]
+
+ *) Function EC_POINTs_mul for simultaneous scalar multiplication
+ of an arbitrary number of elliptic curve points, optionally
+ including the generator defined for the EC_GROUP.
+ EC_POINT_mul is a simple wrapper function for the typical case
+ that the point list has just one item (besides the optional
+ generator).
+ [Bodo Moeller]
+
+ *) First EC_METHODs for curves over GF(p):
+
+ EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
+ operations and provides various method functions that can also
+ operate with faster implementations of modular arithmetic.
+
+ EC_GFp_mont_method() reuses most functions that are part of
+ EC_GFp_simple_method, but uses Montgomery arithmetic.
+
+ [Bodo Moeller; point addition and point doubling
+ implementation directly derived from source code provided by
+ Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
+
+ *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
+ crypto/ec/ec_lib.c):
+
+ Curves are EC_GROUP objects (with an optional group generator)
+ based on EC_METHODs that are built into the library.
+
+ Points are EC_POINT objects based on EC_GROUP objects.
+
+ Most of the framework would be able to handle curves over arbitrary
+ finite fields, but as there are no obvious types for fields other
+ than GF(p), some functions are limited to that for now.
+ [Bodo Moeller]
+
+ *) Add the -HTTP option to s_server. 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 <jeremy@baymoo.org>]
+
+ *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
+ in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
+ [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 <madwolf@hackmasters.net>]
+
+ *) 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 <madwolf@opensca.org>]
+
+ *) 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]
+
+ *) New function EVP_CIPHER_CTX_set_padding() this is used to
+ disable standard block padding (aka PKCS#5 padding) in the EVP
+ API, which was previously mandatory. This means that the data is
+ not padded in any way and so the total length much be a multiple
+ of the block size, otherwise an error occurs.
+ [Steve Henson]
+
+ *) Initial (incomplete) OCSP SSL support.
+ [Steve Henson]
+
+ *) Fix CPU detection on Irix 6.x.
+ [Kurt Hockenbury <khockenb@stevens-tech.edu> and
+ "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
+
+ *) New function OCSP_parse_url(). This splits up a URL into its host,
+ port and path components: primarily to parse OCSP URLs. New -url
+ option to ocsp utility.
+ [Steve Henson]
+
+ *) New nonce behavior. The return value of OCSP_check_nonce() now
+ reflects the various checks performed. Applications can decide
+ whether to tolerate certain situations such as an absent nonce
+ in a response when one was present in a request: the ocsp application
+ just prints out a warning. New function OCSP_add1_basic_nonce()
+ this is to allow responders to include a nonce in a response even if
+ the request is nonce-less.
+ [Steve Henson]
+
+ *) Use the cached encoding of an X509_NAME structure rather than
+ copying it. This is apparently the reason for the libsafe "errors"
+ but the code is actually correct.
+ [Steve Henson]
+
+ *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
+ skipped when using openssl x509 multiple times on a single input file,
+ e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
+ [Bodo Moeller]
+
+ *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
+ set string type: to handle setting ASN1_TIME structures. Fix ca
+ utility to correctly initialize revocation date of CRLs.
+ [Steve Henson]
+
+ *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
+ the clients preferred ciphersuites and rather use its own preferences.
+ Should help to work around M$ SGC (Server Gated Cryptography) bug in
+ Internet Explorer by ensuring unchanged hash method during stepup.
+ [Lutz Jaenicke]
+
+ *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
+ to aes and add a new 'exist' option to print out symbols that don't
+ appear to exist.
+ [Steve Henson]
+
+ *) Additional options to ocsp utility to allow flags to be set and
+ additional certificates supplied.
+ [Steve Henson]
+
+ *) Add the option -VAfile to 'openssl ocsp', so the user can give the
+ OCSP client a number of certificate to only verify the response
+ signature against.
+ [Richard Levitte]
+
+ *) 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.
+ [Ulf Moeller, Bodo Moeller]
+
+ *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
+ handle the new API. Currently only ECB, CBC modes supported. Add new
+ AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
+ for TLS" draft-ietf-tls-ciphersuite-03.txt.
+ [Ben Laurie, Steve Henson]
+
+ *) In the NCONF_...-based implementations for CONF_... queries
+ (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
+ a temporary CONF structure with the data component set to NULL
+ (which gives segmentation faults in lh_retrieve).
+ Instead, use NULL for the CONF pointer in CONF_get_string and
+ CONF_get_number (which may use environment variables) and directly
+ return NULL from CONF_get_section.
+ [Bodo Moeller]
+
+ *) Fix potential buffer overrun for EBCDIC.
+ [Ulf Moeller]
+
+ *) New function OCSP_copy_nonce() to copy nonce value (if present) from
+ request to response.
+ [Steve Henson]
+
+ *) Functions for OCSP responders. OCSP_request_onereq_count(),
+ OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
+ extract information from a certificate request. OCSP_response_create()
+ creates a response and optionally adds a basic response structure.
+ OCSP_basic_add1_status() adds a complete single response to a basic
+ reponse and returns the OCSP_SINGLERESP structure just added (to allow
+ extensions to be included for example). OCSP_basic_add1_cert() adds a
+ certificate to a basic response and OCSP_basic_sign() signs a basic
+ response with various flags. New helper functions ASN1_TIME_check()
+ (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
+ (converts ASN1_TIME to GeneralizedTime).
+ [Steve Henson]
+
+ *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
+ in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
+ structure from a certificate. X509_pubkey_digest() digests tha public_key
+ contents: this is used in various key identifiers.
+ [Steve Henson]
+
+ *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
+ keyUsage if basicConstraints absent for a CA.
+ [Steve Henson]
+
+ *) Make SMIME_write_PKCS7() write mail header values with a format that
+ is more generally accepted (no spaces before the semicolon), since
+ some programs can't parse those values properly otherwise. Also make
+ sure BIO's that break lines after each write do not create invalid
+ headers.
+ [Richard Levitte]
+
+ *) Make sk_sort() tolerate a NULL argument.
+ [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
+
+ *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
+ passed by the function are trusted implicitly. If any of them signed the
+ reponse then it is assumed to be valid and is not verified.
+ [Steve Henson]
+
+ *) Zero the premaster secret after deriving the master secret in
+ DH ciphersuites.
+ [Steve Henson]
+
+ *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
+ to data. This was previously part of the PKCS7 ASN1 code. This
+ was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
+ [Steve Henson, reported by Kenneth R. Robinette
+ <support@securenetterm.com>]
+
+ *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
+ routines: without these tracing memory leaks is very painful.
+ Fix leaks in PKCS12 and PKCS7 routines.
+ [Steve Henson]
+
+ *) Fix for Irix with NO_ASM.
+ ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
+
+ *) Add some EVP_add_digest_alias registrations (as found in
+ OpenSSL_add_all_digests()), to SSL_library_init()
+ aka OpenSSL_add_ssl_algorithms(). This provides improved
+ compatibility with peers using X.509 certificates
+ with unconventional AlgorithmIdentifier OIDs.
+ [Bodo Moeller]
+
+ *) ./config script fixes.
+ [Ulf Moeller, Richard Levitte]
+
+ *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
+ Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
+ effectively meant GeneralizedTime would never be used. Now it
+ is initialised to -1 but X509_time_adj() now has to check the value
+ and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
+ V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
+ [Steve Henson, reported by Kenneth R. Robinette
+ <support@securenetterm.com>]
+
+ *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
+ result in a zero length in the ASN1_INTEGER structure which was
+ not consistent with the structure when d2i_ASN1_INTEGER() was used
+ and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
+ to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
+ where it did not print out a minus for negative ASN1_INTEGER.
+ [Steve Henson]
+
+ *) Fix 'openssl passwd -1'.
+ [Bodo Moeller]
+
+ *) Add summary printout to ocsp utility. The various functions which
+ convert status values to strings have been renamed to:
+ OCSP_response_status_str(), OCSP_cert_status_str() and
+ OCSP_crl_reason_str() and are no longer static. New options
+ to verify nonce values and to disable verification. OCSP response
+ printout format cleaned up.
+ [Steve Henson]
+
+ *) Add additional OCSP certificate checks. These are those specified
+ in RFC2560. This consists of two separate checks: the CA of the
+ certificate being checked must either be the OCSP signer certificate
+ or the issuer of the OCSP signer certificate. In the latter case the
+ OCSP signer certificate must contain the OCSP signing extended key
+ usage. This check is performed by attempting to match the OCSP
+ signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
+ in the OCSP_CERTID structures of the response.
+ [Steve Henson]
+
+ *) Initial OCSP certificate verification added to OCSP_basic_verify()
+ and related routines. This uses the standard OpenSSL certificate
+ verify routines to perform initial checks (just CA validity) and
+ to obtain the certificate chain. Then additional checks will be
+ performed on the chain. Currently the root CA is checked to see
+ if it is explicitly trusted for OCSP signing. This is used to set
+ a root CA as a global signing root: that is any certificate that
+ chains to that CA is an acceptable OCSP signing certificate.
+ [Steve Henson]
+
+ *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
+ extensions from a separate configuration file.
+ As when reading extensions from the main configuration file,
+ the '-extensions ...' option may be used for specifying the
+ section to use.
+ [Massimiliano Pala <madwolf@comune.modena.it>]
+
+ *) Change PKCS12_key_gen_asc() so it can cope with non null
+ terminated strings whose length is passed in the passlen
+ parameter, for example from PEM callbacks. This was done
+ by adding an extra length parameter to asc2uni().
+ [Steve Henson, reported by <oddissey@samsung.co.kr>]
+
+ *) New OCSP utility. Allows OCSP requests to be generated or
+ read. The request can be sent to a responder and the output
+ parsed, outputed or printed in text form. Not complete yet:
+ still needs to check the OCSP response validity.
+ [Steve Henson]
+
+ *) New subcommands for 'openssl ca':
+ 'openssl ca -status <serial>' prints the status of the cert with
+ the given serial number (according to the index file).
+ 'openssl ca -updatedb' updates the expiry status of certificates
+ in the index file.
+ [Massimiliano Pala <madwolf@comune.modena.it>]
+
+ *) New '-newreq-nodes' command option to CA.pl. This is like
+ '-newreq', but calls 'openssl req' with the '-nodes' option
+ so that the resulting key is not encrypted.
+ [Damien Miller <djm@mindrot.org>]
+
+ *) New configuration for the GNU Hurd.
+ [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
+
+ *) Initial code to implement OCSP basic response verify. This
+ is currently incomplete. Currently just finds the signer's
+ certificate and verifies the signature on the response.
+ [Steve Henson]
+
+ *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
+ value of OPENSSLDIR. This is available via the new '-d' option
+ to 'openssl version', and is also included in 'openssl version -a'.
+ [Bodo Moeller]
+
*) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
call failed, free the DSA structure.
[Bodo Moeller]
- *) Add another call level for memory allocation routines, thereby
- allowing memory allocation callbacks that can be given file
- name and line number information. The basic functionality
- remains, as well as the original possibility to just replace
- malloc(), realloc() and free(). The new functions that can be
- registered help users provide variants of malloc(), realloc()
- and free() that take two extra arguments, a const char* and an
- int. To register and find out the current settings for those
- hooks, the following functions are provided:
+ *) Allowing defining memory allocation callbacks that will be given
+ file name and line number information in additional arguments
+ (a const char* and an int). The basic functionality remains, as
+ well as the original possibility to just replace malloc(),
+ realloc() and free() by functions that do not know about these
+ additional arguments. To register and find out the current
+ settings for extended allocation functions, the following
+ functions are provided:
CRYPTO_set_mem_ex_functions
CRYPTO_set_locked_mem_ex_functions
CRYPTO_get_mem_ex_functions
CRYPTO_get_locked_mem_ex_functions
- They work the same way as the corresponding CRYPTO_set_mem_functions
- and friends with one exception: giving NULL as arguments will restore
- the internal hooks to internal routines and will still make the above
- functions return 1 and not 0.
-
- This functionality was created as a direct request to add the
- possibility to interface with the Windows debugging routines
- _malloc_dbg, _realloc_dbg and _free_dbg.
- [Richard Levitte]
+ These work the same way as CRYPTO_set_mem_functions and friends.
+ CRYPTO_get_[locked_]mem_functions now writes 0 where such an
+ extended allocation function is enabled.
+ Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
+ a conventional allocation function is enabled.
+ [Richard Levitte, Bodo Moeller]
*) Fix to uni2asc() to cope with zero length Unicode strings.
These are present in some PKCS#12 files.
[Lutz Jaenicke]
*) Change the Unix RAND_poll() variant to be able to poll several
- random devices and only read data for a small fragment of time
- to avoid hangs. Also separate out the Unix variant to it's own
- file, rand_unix.c. For VMS, there's a currently-empty rand_vms.c.
+ random devices, as specified by DEVRANDOM, until a sufficient amount
+ of data has been collected. We spend at most 10 ms on each file
+ (select timeout) and read in non-blocking mode. DEVRANDOM now
+ defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
+ (previously it was just the string "/dev/urandom"), so on typical
+ platforms the 10 ms delay will never occur.
+ Also separate out the Unix variant to its own file, rand_unix.c.
+ For VMS, there's a currently-empty rand_vms.c.
[Richard Levitte]
*) Move OCSP client related routines to ocsp_cl.c. These
projects / openssl.git / blobdiff
