an SSL_CTX's session cache, it is necessary to compare the ssl_version at
the same time (a conflict is defined, courtesy of SSL_SESSION_cmp(), as a
matching id/id_length pair and a matching ssl_version). However, the
SSL_SESSION that will result from the current negotiation does not
necessarily have the same ssl version as the "SSL_METHOD" in use by the
SSL_CTX - part of the work in a handshake is to agree on an ssl version!

This is fixed by having the check function accept an SSL pointer rather
than the SSL_CTX it belongs to.

really see why we need to define these function pointers with MS_FAR
if it's not done cosistently everywhere.

If we decide to support MS_FAR modifiers, it's better to have the

Define the OPENSSL_NO_* macros as NO_* macros for the sake of applications thathaven't yet been changed

The reason is that some parts are only included when certain other

Also, it seems that the rest of the OpenSSL code assumes that all

SSL_add_dir_cert_subjects_to_stack is not implemented on WIN32 and

Rebuild ASN1 error codes to remove unused function and reason codes.

the ID will be padded out to 16 bytes if the callback attempted to generate
a shorter one. The problem is that the uniqueness checking function used in
callbacks may mistakenly think a 9-byte ID is unique when in fact its
padded 16-byte version is not. This makes the checking function detect
SSLv2 cases, and ensures the padded form is checked rather than the shorter
one passed by the callback.

of session IDs. Namely, passing "-id_prefix <text>" will set a
generate_session_id() callback that generates session IDs as random data
with <text> block-copied over the top of the start of the ID. This can be
viewed by watching the session ID s_client's output when it connects.

This is mostly useful for testing any SSL/TLS code (eg. proxies) that wish
to deal with multiple servers, when each of which might be generating a
unique range of session IDs (eg. with a certain prefix).

SSL/TLS session IDs in a server. According to RFC2246, the session ID is an
arbitrary value chosen by the server. It can be useful to have some control
over this "arbitrary value" so as to choose it in ways that can aid in
things like external session caching and balancing (eg. clustering). The
default session ID generation is to fill the ID with random data.

The callback used by default is built in to ssl_sess.c, but registering a
callback in an SSL_CTX or in a particular SSL overrides this. BTW: SSL
callbacks will override SSL_CTX callbacks, and a new SSL structure inherits
any callback set in its 'parent' SSL_CTX. The header comments describe how
this mechanism ticks, and source code comments describe (hopefully) why it
ticks the way it does.

Man pages are on the way ...

need reversing.

Also, I personally find line breaks during parameter lists (ie a line
ending in a comma) easier to read at a glance than line breaks at the end
of a function call and before a dereference on the return value (ie a line
ending in a closed-bracket followed by a line starting with "->").
