Despite the man page not changing, the d2i_SSL_SESSION() prototype changed
between OpenSSL 0.9.7e and 0.9.7g:
0.9.7e:
SSL_SESSION *d2i_SSL_SESSION(
SSL_SESSION **a,
unsigned char **pp,
long length);
0.9.7g:
SSL_SESSION *d2i_SSL_SESSION(
SSL_SESSION **a,
const unsigned char * const *pp,
long length);
This causes gcc 2.96 to generate a spurious warning for the following
code (Postfix 2.2.x tls/tls_session.c line 171):
tls_session.c: In function `tls_session_activate':
tls_session.c:171: warning: passing arg 2 of `d2i_SSL_SESSION' from
incompatible pointer type
SSL_SESSION *tls_session_activate(char *session_data, int session_data_len)
{
SSL_SESSION *session;
unsigned char *ptr;
/*
* Activate the SSL_SESSION object.
*/
ptr = (unsigned char *) session_data;
session = d2i_SSL_SESSION((SSL_SESSION **) 0, &ptr, session_data_len);
if (!session)
tls_print_errors();
return (session);
}
I don't see why the compiler objects to passing a pointer to a pointer
to a constant character, to a function that expects a pointer to a constant
pointer to a constant character, anyway just in case anyone asks, this is
not a real problem.
Still, if the interface changes, the documentation should probably
change also.
