Hi everybody,
I just wanted to point out a trap, which I encountered. I am developing an SSL
enhancement
for our SMTP interface and I am using
OpenSSL. I start testing under Win2000 and everything worked fine. After that I tried
it
out under NT4.0 (SP6) and the application hang up
on SSL_connect and SSL_accept. As I debugged the whole thing, I found out that the
critical line was in rand_win.c.
while (rc == ERROR_MORE_DATA)
{
buf = realloc(buf,bufsz+8192);
if (!buf)
break;
bufsz += 8192;
length = bufsz;
rc = RegQueryValueEx(HKEY_PERFORMANCE_DATA, "Global",
TRAP LINE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
NULL, NULL, buf, &length);
}
A view lines above there is a comment to use this only under WinNT. Funny it works the
opposite way for me. I removed the critical part and
everything works fine again. I am not sure, whether this applies general to WinNT or
just
on my computer, but I tried the application on another
NT computer, and there it also hung up.
Let me know your comments (but please reply direct, as I am not on the openssl_dev
list).
Cheers,
Wolfgang Marczy.
