Changes from upstream functions?

[Julien ÉLIE]

Hi,

While reading nnrpd/tls.c, I found the following check:

    if (ok==0)
    {
      syslog(L_NOTICE, "verify error:num=%d:%s", err,
             X509_verify_cert_error_string(err));

        if (verify_depth >= depth) {
            ok = 0;
            verify_error = X509_V_OK;
        } else {
            ok = 0;
            verify_error = X509_V_ERR_CERT_CHAIN_TOO_LONG;
        }
    }


It looked weird to me that "ok = 0" was used twice.

As this function is taken from OpenSSL apps/s_cb.c, I checked it
and there is "ok = 1" for X509_V_OK.


My question is:  how can we *easily* catch bug-fixes or improvements
for all the code we have in INN taken from other projects?
I do not see any obvious solution which is not very time-consuming...
