Segfault in HSPOST control command
A segfault occurs in the HSPOST command if node->rs->is_hs_dir
is checked but the router_status entry for the node does not exist. I have a fix for this issue on my Github - https://github.com/DonnchaC/tor/commit/27f006bcad4a1a27339130ffb09637f4baaf7dbe
if (!node->rs->is_hs_dir) {
connection_printf_to_buf(conn, "552 Server \"%s\" is not a HSDir"
"\r\n", server);
goto done;
}
