Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Rework the system to generate shared libraries:
- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.so.0
to libcrypto.so.0.9.7. There is extended info in Configure for
that.
- Make as few rebuilds of the shared libraries as possible.
- Still avoid linking the OpenSSL programs with the shared libraries.
- When installing, install the shared libraries separately from the
static ones.
[Richard Levitte]
*) Fix for non blocking accept BIOs. Added new I/O special reason
BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
with non blocking I/O was not possible because no retry code was
implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
this case.
[Steve Henson]
*) Added the beginnings of Rijndael support.
[Ben Laurie]
*) Fix for bug in DirectoryString mask setting. Add support for
X509_NAME_print_ex() in 'req' and X509_print_ex() function
to allow certificate printing to more controllable, additional
'certopt' option to 'x509' to allow new printing options to be
set.
*) Clean old EAY MD5 hack from e_os.h.
[Richard Levitte]
*) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
and not in SSL_clear because the latter is also used by the
accept/connect functions; previously, the settings made by
SSL_set_read_ahead would be lost during the handshake.
[Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
*) Correct util/mkdef.pl to be selective about disabled algorithms.
Previously, it would create entries for disableed algorithms no
matter what.
[Richard Levitte]
Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
*) In ssl23_get_client_hello, generate an error message when faced
with an initial SSL 3.0/TLS record that is too small to contain the
first two bytes of the ClientHello message, i.e. client_version.
(Note that this is a pathologic case that probably has never happened
in real life.) The previous approach was to use the version number
should not depend on that one because it is not authenticated
by the Finished messages.
[Bodo Moeller]
*) More robust randomness gathering functions for Windows.
[Jeffrey Altman <jaltman@columbia.edu>]
*) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
not set then we don't setup the error code for issuer check errors
to avoid possibly overwriting other errors which the callback does
handle. If an application does set the flag then we assume it knows
what it is doing and can handle the new informational codes
appropriately.
[Steve Henson]
*) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
a general "ANY" type, as such it should be able to decode anything
including tagged types. However it didn't check the class so it would
wrongly interpret tagged types in the same way as their universal
counterpart and unknown types were just rejected. Changed so that the
tagged and unknown types are handled in the same way as a SEQUENCE:
that is the encoding is stored intact. There is also a new type
"V_ASN1_OTHER" which is used when the class is not universal, in this
case we have no idea what the actual type is so we just lump them all
together.
[Steve Henson]
*) On VMS, stdout may very well lead to a file that is written to
in a record-oriented fashion. That means that every write() will
write a separate record, which will be read separately by the
programs trying to read from it. This can be very confusing.
The solution is to put a BIO filter in the way that will buffer
text until a linefeed is reached, and then write everything a
line at a time, so every record written will be an actual line,
not chunks of lines and not (usually doesn't happen, but I've
seen it once) several lines in one record. BIO_f_linebuffer() is
the answer.
Currently, it's a VMS-only method, because that's where it has
been tested well enough.
[Richard Levitte]
*) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
(Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
but it was in 0.9.6-beta[12].)
*) Disable the check for content being present when verifying detached
signatures in pk7_smime.c. Some versions of Netscape (wrongly)
include zero length content when signing messages.
[Steve Henson]
*) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
BIO_ctrl (for BIO pairs).
*) Add DSO method for VMS.
[Richard Levitte]
*) Bug fix: Montgomery multiplication could produce results with the
wrong sign.
[Ulf Möller]
*) Add RPM specification openssl.spec and modify it to build three
packages. The default package contains applications, application
documentation and run-time libraries. The devel package contains
include files, static libraries and function documentation. The
doc package contains the contents of the doc directory. The original
openssl.spec was provided by Damien Miller <djm@mindrot.org>.
[Richard Levitte]
*) Add a large number of documentation files for many SSL routines.
[Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
*) Add a configuration entry for Sony News 4.
[NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
*) Don't set the two most significant bits to one when generating a
random number < q in the DSA library.
*) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
the underlying transport is blocking) if a handshake took place.
(The default behaviour is needed by applications such as s_client
and s_server that use select() to determine when to use SSL_read;
but for applications that know in advance when to expect data, it
just makes things more complicated.)
[Bodo Moeller]
*) Add RAND_egd_bytes(), which gives control over the number of bytes read
from EGD.
[Ben Laurie]
*) Add a few more EBCDIC conditionals that make `req' and `x509'
work better on such systems.
[Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
*) Add two demo programs for PKCS12_parse() and PKCS12_create().
Update PKCS12_parse() so it copies the friendlyName and the
keyid to the certificates aux info.
[Steve Henson]
*) Fix bug in PKCS7_verify() which caused an infinite loop
if there was more than one signature.
[Sven Uszpelkat <su@celocom.de>]
*) Major change in util/mkdef.pl to include extra information
about each symbol, as well as presentig variables as well
as functions. This change means that there's n more need
to rebuild the .num files when some algorithms are excluded.
[Richard Levitte]
*) Allow the verify time to be set by an application,
rather than always using the current time.
[Steve Henson]
*) Phase 2 verify code reorganisation. The certificate
verify code now looks up an issuer certificate by a
number of criteria: subject name, authority key id
and key usage. It also verifies self signed certificates
by the same criteria. The main comparison function is
X509_check_issued() which performs these checks.
Lot of changes were necessary in order to support this
without completely rewriting the lookup code.
Authority and subject key identifier are now cached.
The LHASH 'certs' is X509_STORE has now been replaced
by a STACK_OF(X509_OBJECT). This is mainly because an
LHASH can't store or retrieve multiple objects with
the same hash value.
As a result various functions (which were all internal
use only) have changed to handle the new X509_STORE
