In openvpn-2.0.9 socket_connect() (socket.c), print_sockaddr()
consumes memory without bounds if the server is permanently down or
unreachable becauses gc_free() is not called from within the loop.
Memory is consumed at 72 bytes every 5 seconds or 1.2 megabytes for each
24 hours (plus malloc overhead). That's enough to bring my openwrt box
to its knees within a week or so.
Proposed solution (untested):
msg (D_LINK_ERRORS | M_ERRNO_SOCK,
"TCP: connect to %s failed, will try again in %d seconds",
print_sockaddr (remote, &gc),
connect_retry_seconds);
+ gc_free (&gc);
+ gc = gc_new ();
