[Unbound-users] Compile ldns 1.6.16/unbound 1.4.19 on Solaris 10.

HI again,

Sorry to get back at this... I wrongly said it was all ok...

I did the change, recompile, and got it working, but on Solaris 11... 
Not 10...

So on Solaris 11, with these options :

./configure --prefix=/opt/unbound --disable-gost --disable-sha2 
--disable-ecdsa

  and the fixed #ifdefs in dane.c. It works... (Compiles, run, all ok)_.


But on Solaris 10, with the same options to configure, I get an error 
for X509_check_ca used in dane.c :

./libtool --tag=CC --quiet --mode=compile cc -I. -I. -DHAVE_CONFIG_H -O2 
-g -xc99 -D__EXTENSIONS__ -D_BSD_SOURCE -D_POSIX_C_SOURCE=200112 
-D_XOPEN_SOURCE=600 -D_ALL_SOURCE -I/usr/sfw/include -c ./dane.c -o dane.lo
"./dane.c", line 295: warning: implicit function declaration: X509_check_ca

and at the end:

./libtool --tag=CC --quiet --mode=link cc -O2 -g -xc99 -D__EXTENSIONS__ 
-D_BSD_SOURCE -D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600

gmake: *** [libldns.la] Error 2

So, again, any help, some ifdef missing  ?

IN dane.c, I can see two calls to X509_check_ca,

    281    /* Pop n+1 certs and return the last popped.
    282     */
    283    static ldns_status
    284    ldns_dane_get_nth_cert_from_validation_chain(
    285            X509** cert, STACK_OF(X509)* chain, int n, bool ca)
    286    {
    287        if (n >= sk_X509_num(chain) || n < 0) {
    288            return LDNS_STATUS_DANE_OFFSET_OUT_OF_RANGE;
    289        }
    290        *cert = sk_X509_pop(chain);
    291        while (n-- > 0) {
    292            X509_free(*cert);
    293            *cert = sk_X509_pop(chain);
    294        }
    295        if (ca && ! X509_check_ca(*cert)) {
    296            return LDNS_STATUS_DANE_NON_CA_CERTIFICATE;
    297        }
    298        return LDNS_STATUS_OK;
    299    }

And:

    555    /* Return whether any certificate from the chain with 
selector/matching_type
    556     * matches data.
    557     * ca should be true if the certificate has to be a CA 
certificate too.
    558     */
    559    static ldns_status
    560    ldns_dane_match_any_cert_with_data(STACK_OF(X509)* chain,
    561            ldns_tlsa_selector    selector,
    562            ldns_tlsa_matching_type matching_type,
    563            ldns_rdf* data, bool ca)
    564    {
    565        ldns_status s = LDNS_STATUS_DANE_TLSA_DID_NOT_MATCH;
    566        size_t n, i;
    567        X509* cert;
    568
    569        n = (size_t)sk_X509_num(chain);
    570        for (i = 0; i < n; i++) {
    571            cert = sk_X509_pop(chain);
    572            if (! cert) {
    573                s = LDNS_STATUS_SSL_ERR;
    574                break;
    575            }
    576            s = ldns_dane_match_cert_with_data(cert,
    577                    selector, matching_type, data);
    578            if (ca && s == LDNS_STATUS_OK && ! 
X509_check_ca(cert)) {
    579                s = LDNS_STATUS_DANE_NON_CA_CERTIFICATE;
    580            }
    581            X509_free(cert);
    582            if (s != LDNS_STATUS_DANE_TLSA_DID_NOT_MATCH) {
    583                break;
    584            }
    585            /* when s == LDNS_STATUS_DANE_TLSA_DID_NOT_MATCH,
    586             * try to match the next certificate
    587             */
    588        }
    589        return s;
    590    }
    591


Thank's.
