>Description:
While debugging a problem with IPSEC on my 6.4 box, I noticed that libipsec uses the wrong constant, as per subject. This occurs in lib/libipsec/pfkey.c:665 in pfkey_send_register in both my 6.4 version as in the HEAD version (http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libipsec/pfkey.c?annotate=1.9.10.1.2.1):

    if (satype == PF_UNSPEC) {

Line 1389 and this snippet from sbin/setkey/setkey.c show that it should indeed be SADB_SATYPE_UNSPEC

    if (pfkey_send_register(so, SADB_SATYPE_UNSPEC) < 0)
        return -1;                                                         

Since these constants both have the value 0, this wrong constant has never caused any problems, but for clarity and to prevent possible future bugs, it's probably best to change it?
