Description Rich Megginson 2008-07-09 16:03:37 EDT
Platform tested: Fedora 8 i386 - latest updates
Testing with fedora-ds-admin 1.1.6 (pre-release)

When fedora-ds-admin starts up, I get the following errors in
[Wed Jul 09 13:49:26 2008] [notice] child pid 7621 exit signal Segmentation
fault (11)
[Wed Jul 09 13:49:27 2008] [error] SSL_InheritMPServerSIDCache failed
[Wed Jul 09 13:49:27 2008] [error] SSL Library Error: -8191 Library Failure

The code in nss_init_Module() does the following:
    ap_mpm_query(AP_MPMQ_MAX_THREADS, &threaded);
    if (!threaded)
        SSL_ConfigMPServerSIDCache(mc->session_cache_size, (PRUint32)
mc->session_cache_timeout, (PRUint32) mc->ssl3_session_cache_timeout, NULL);
        SSL_ConfigServerSessionIDCache(mc->session_cache_size, (PRUint32)
mc->session_cache_timeout, (PRUint32) mc->ssl3_session_cache_timeout, NULL);

fedora-ds-admin uses multi-threaded mode.  But because of the way Apache works,
it always forks child processes, which calls into this function:
void nss_init_Child(apr_pool_t *p, server_rec *base_server)
    if (SSL_InheritMPServerSIDCache(NULL) != SECSuccess) {

The problem is that you cannot call SSL_InheritMPServerSIDCache() unless you
have first called SSL_ConfigMPServerSIDCache().

I suppose the best thing to do would be to init the SSL caches for both mp and
mt modes.  Barring that, it's probably safe to just skip
SSL_InheritMPServerSIDCache in nss_init_Child if mt mode.

I'm also having a core dump problem.  I think the problem is that none of the
SSL init stuff in nss_init_Child() should be done if ssl is not enabled,
similar to the way nss_init_Module works.  Attached is a patch.
