Kees Cook 46d30cb104 net: ip6_gre: Distribute switch variables for initialization ... Variables declared in a switch statement before any case statements cannot be automatically initialized with compiler instrumentation (as they are not part of any execution flow). With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain. To avoid these problems, move such variables into the "case" where they're used or lift them up into the main function body. net/ipv6/ip6_gre.c: In function ‘ip6gre_err’: net/ipv6/ip6_gre.c:440:32: warning: statement will never be executed [-Wswitch-unreachable] 440 | struct ipv6_tlv_tnl_enc_lim *tel; | ^~~ net/ipv6/ip6_tunnel.c: In function ‘ip6_tnl_err’: net/ipv6/ip6_tunnel.c:520:32: warning: statement will never be executed [-Wswitch-unreachable] 520 | struct ipv6_tlv_tnl_enc_lim *tel; | ^~~ [1] https://bugs.llvm.org/show_bug.cgi?id=44916 Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: David S.
