+Subject: [PATCH] Zero-initialize sockaddr_storage in inet_parse()
+
+inet_parse() only sets sin6_family, sin6_addr, and sin6_port, leaving
+sin6_scope_id and sin6_flowinfo uninitialized. When the caller's
+inet_addr_t is on the stack, these fields contain garbage which the
+kernel may interpret - e.g., a non-zero sin6_scope_id causes bind() to
+fail with ENODEV when the garbage value doesn't match any interface
+index.
+
+Zero the entire struct before populating it.
