+Subject: [PATCH] networking: fix uninitialized memory when displaying IPv6
+ addresses
+
+After commit 8e74adab0107658e3dc04ed342206272a284f43e
+("libbb: make INET[6]_rresolve use sockaddr2{host,dotted}_noport")
+INET_sprint6 uses more than just sin6_addr, it also tries to display the
+scope id, which is uninitialized when called from ife_print6.
