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.

a5224c3420 Changes to the Kerberos SSL code by Jeffrey Altman <jaltman@columbia.edu>
His comments are:

 . adds use of replay cache to protect against replay attacks

 . adds functions kssl_tgt_is_available() and
   kssl_keytab_is_available() which are used within s3_lib.c
   and ssl_lib.c to determine at runtime whether or not
   KRB5 ciphers can be supported during the current session.

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.

130832150c Fixes for Win32 build.
This is mostly a work around for the old VC++ problem
that it treats func() as func(void).

Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.

The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.

Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)

26a3a48d65 There have been a number of complaints from a number of sources that names
like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.

e11f0de67f Copy DH key (if available) in addition to the bare parameters
in SSL_new.
If SSL_OP_SINGLE_DH_USE is set, don't waste time in SSL_[CTX_]set_tmp_dh
on computing a DH key that will be ignored anyway.

ssltest -dhe1024dsa (w/ 160-bit sub-prime) had an unfair performance
advantage over -dhe1024 (safe prime): SSL_OP_SINGLE_DH_USE was
effectively always enabled because SSL_new ignored the DH key set in
the SSL_CTX.  Now -dhe1024 takes the server only about twice as long
as -dhe1024dsa instead of three times as long (for 1024 bit RSA
with 1024 bit DH).

d3442bc780 Move the registration of callback functions to special functions
designed for that.  This removes the potential error to mix data and
function pointers.

Please note that I'm a little unsure how incorrect calls to the old
ctrl functions should be handled, in som cases.  I currently return 0
and that's it, but it may be more correct to generate a genuine error
in those cases.

a9188d4e17 Compaq C 6.2 for VMS will complain when we want to convert
non-function pointers to function pointers and vice versa.
The current solution is to have unions that describe the
conversion we want to do, and gives us the ability to extract
the type of data we want.

The current solution is a quick fix, and can probably be made
in a more general or elegant way.

15d21c2df4 Add a bunch of SSL_xxx() functions for configuring the temporary RSA and DH
private keys and/or callback functions which directly correspond to their
SSL_CTX_xxx() counterparts but work on a per-connection basis. This is needed
for applications which have to configure certificates on a per-connection
basis (e.g. Apache+mod_ssl) instead of a per-context basis (e.g.
s_server).

For the RSA certificate situation is makes no difference, but for the DSA
certificate situation this fixes the "no shared cipher" problem where the
OpenSSL cipher selection procedure failed because the temporary keys were not
overtaken from the context and the API provided no way to reconfigure them.

The new functions now let applications reconfigure the stuff and they are in
detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback.  Additionally a new
non-public-API function ssl_cert_instantiate() is used as a helper function
and also to reduce code redundancy inside ssl_rsa.c.
