Subject: [zebra 19080] suspected memory leakage upon static route deletion upon deletion of a static route entry, at the end of zebra/zebra_rib.c/static_delete_ipv4(), there's a call to XFREE to deallocate the 'struct static_ipv4'. However, in the case of a static with ifname as nexthop (type==STATIC_IPV4_IFNAME), this struct holds a pointer to a dynamically allocated ifname string buffer (si->gate.ifname, see its allocation within static_add_ipv4() using XSTRDUP). IMO, the attached patch is required. Notes: the same applies to IPv6 statics as well (fix included in patch); and, I admit I haven't yet tested that, but it seems simple enough to be working... ;->
