a661b65357 New functions SSL[_CTX]_set_msg_callback().
New macros SSL[_CTX]_set_msg_callback_arg().

Message callback imlementation for SSL 3.0/TLS 1.0 (no SSL 2.0 yet).

New '-msg' option for 'openssl s_client' and 'openssl s_server'
that enable a message callback that displays all protocol messages.


In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert if
client_version is smaller than the protocol version in use.
Also change ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0
if the client demanded SSL 3.0 but only TLS 1.0 is enabled; then the
client will at least see that alert.

Fix SSL[_CTX]_ctrl prototype (void * instead of char * for generic
pointer).

Add/update some OpenSSL copyright notices.

882e891284 More Kerberos SSL changes from Jeffrey Altman <jaltman@columbia.edu>
His comments are:

First, it corrects a problem introduced in the last patch where the
kssl_map_enc() would intentionally return NULL for valid ENCTYPE
values.  This was done to prevent verification of the kerberos 5
authenticator from being performed when Derived Key ciphers were
in use.  Unfortunately, the authenticator verification routine was
not the only place that function was used.  And it caused core dumps.

Second, it attempt to add to SSL_SESSION the Kerberos 5 Client
Principal Name.

acdf4afb91 More Kerberos SSL patches from Vern Staats <staatsvr@asc.hpc.mil>.
His comments are:

This patch fixes the problem of modern Kerberos using "derived keys"
to encrypt the authenticator by disabling the authenticator check
for all derived keys enctypes.

I think I've got all the bugfixes that Jeffrey and I discussed rolled
into this.  There were some problems with Jeffrey's code to convert
the authenticator's Kerberos timestring into struct tm (e.g. Z, -1900;
it helps to have an actual decryptable authenticator to play with).
So I've shamelessly pushed in my code, while stealing some bits from
Jeffrey.

2a1ef75435 Patches from Vern Staats <staatsvr@asc.hpc.mil> to get Kerberos 5 in
SSL according to RFC 2712.  His comment is:

This is a patch to openssl-SNAP-20010702 to support Kerberized SSL
authentication.  I'm expecting to have the full kssl-0.5 kit up on
sourceforge by the end of the week.  The full kit includes patches
for mod-ssl, apache, and a few text clients.  The sourceforge URL
is http://sourceforge.net/projects/kssl/ .

Thanks to a note from Simon Wilkinson I've replaced my KRB5 AP_REQ
message with a real KerberosWrapper struct.  I think this is fully
RFC 2712 compliant now, including support for the optional
authenticator field.  I also added openssl-style ASN.1 macros for
a few Kerberos structs; see crypto/krb5/ if you're interested.

323f289c48 Change all calls to low level digest routines in the library and
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

745c70e565 Move MAC computations for Finished from ssl3_read_bytes into
ssl3_get_message, which is more logical (and avoids a bug,
in addition to the one that I introduced yesterday :-)
and makes Microsoft "fast SGC" less special.
MS SGC should still work now without an extra state of its own
(it goes directly to SSL3_ST_SR_CLNT_HELLO_C, which is the usual state
for reading the body of a Client Hello message), however this should
be tested to make sure, and I don't have a MS SGC client.

b56bce4fc7 New structure type SESS_CERT used instead of CERT inside SSL_SESSION.
While modifying the sources, I found some inconsistencies on the use of
s->cert vs. s->session->sess_cert; I don't know if those could
really have caused problems, but possibly this is a proper bug-fix
and not just a clean-up.

9d5cceac6f No actual change, but the cert_st member of struct ssl_session_st is now
called sess_cert instead of just cert.  This is in preparation of further
changes: Probably often when s->session->sess_cert is used, we should
use s->cert instead; s->session->sess_cert should be a new structure
containing only the stuff that is for just one connection (e.g.
the peer's certificate, which the SSL client implementations currently
store in s->session->[sess_]cert, which is a very confusing thing to do).
