mod_geoip crashes lighttpd 1.5.x on FreeBSD 7.2 AMD64
The backtrace will look something like this:
#0 0x0000000801809660 in _GeoIP_addr_to_num () from /usr/local/lib/libGeoIP.so.5
Looking further into this, this function is passed the addr from mod_geoip.c:228:
remote_ip = inet_ntop_cache_get_ip(srv, &(con->dst_addr));
remote_ip here is what is passed to the above function that fails. I am not quite sure why we are calling inet_ntop_cache_get_ip() since this is already called in connections.c, and the dst_addr_buf field is populated with the results. Changing the above line (mod_geoip.c:228) to:
remote_ip = con->dst_addr_buf->ptr;
fixes this and saves a few cycles. There may be a similar problem in mod_trigger_b4_dl, but I do not use that module.
(add to default build to reduce distributor package maintenance)
