Summary	0001629: Memory issue with upnp.c
Description	There is a line that causes some error messages in upnp.c, already marked by a // BADNESS! comment. It would seem that the line should be something like upnp->iface = GNUNET_strdup(name); On some systems the upnp->iface points to random data at a later point in execution, specifically when UPNP_discover_ is called.
Additional Information	static int process_if (void cls, const char name, int isDefault, const struct sockaddr addr, socklen_t addrlen) { struct GNUNET_NAT_UPNP_Handle upnp = cls; if (addr && GNUNET_NAT_cmp_addr (upnp->addr, addr) == 0) { upnp->iface = name; // BADNESS! return GNUNET_SYSERR; } return GNUNET_OK; }
Tags	No tags attached.

Christian Grothoff 2011-06-10 09:11 manager ~0004352	Based on various discussions, I'm now pretty convinced that this entire upnp code will just go away. So no point in fixing this one.
