Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Finish off removing the remaining LHASH function pointer casts.
There should no longer be any prototype-casting required when using
the LHASH abstraction, and any casts that remain are "bugs". See
the callback types and macros at the head of lhash.h for details
(and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
[Geoff Thorpe]
*) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
If an EGD or PRNGD is running and enough entropy is returned, automatic
seeding like with /dev/[u]random will be performed.
Positions tried are: /etc/entropy, /var/run/egd-pool.
[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.
[Richard Levitte]
*) Move OCSP client related routines to ocsp_cl.c. These
provide utility functions which an application needing
to issue a request to an OCSP responder and analyse the
response will typically need: as opposed to those which an
OCSP responder itself would need which will be added later.
OCSP_request_sign() signs an OCSP request with an API similar
to PKCS7_sign(). OCSP_response_status() returns status of OCSP
response. OCSP_response_get1_basic() extracts basic response
from response. OCSP_resp_find_status(): finds and extracts status
information from an OCSP_CERTID structure (which will be created
when the request structure is built). These are built from lower
level functions which work on OCSP_SINGLERESP structures but
wont normally be used unless the application wishes to examine
extensions in the OCSP response for example.
Replace nonce routines with a pair of functions.
OCSP_request_add1_nonce() adds a nonce value and optionally
generates a random value. OCSP_check_nonce() checks the
validity of the nonce in an OCSP response.
[Steve Henson]
*) Change function OCSP_request_add() to OCSP_request_add0_id().
This doesn't copy the supplied OCSP_CERTID and avoids the
need to free up the newly created id. Change return type
to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
This can then be used to add extensions to the request.
Deleted OCSP_request_new(), since most of its functionality
is now in OCSP_REQUEST_new() (and the case insensitive name
clash) apart from the ability to set the request name which
will be added elsewhere.
[Steve Henson]
*) Update OCSP API. Remove obsolete extensions argument from
various functions. Extensions are now handled using the new
OCSP extension code. New simple OCSP HTTP function which
can be used to send requests and parse the response.
[Steve Henson]
*) Fix the PKCS#7 (S/MIME) code to work with new ASN1. 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 <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.
*) 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.
*) 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.
