[ Upstream commit bc5b6c0b62b932626a135f516a41838c510c6eba ] 'protocol' is a user-controlled value, so sanitize it after the bounds check to avoid using it for speculative out-of-bounds access to arrays indexed by it. This addresses the following accesses detected with the help of smatch: * net/netlink/af_netlink.c:654 __netlink_create() warn: potential spectre issue 'nlk_cb_mutex_keys' [w] * net/netlink/af_netlink.c:654 __netlink_create() warn: potential spectre issue 'nlk_cb_mutex_key_strings' [w] * net/netlink/af_netlink.c:685 netlink_create() warn: potential spectre issue 'nl_table' [w] (local cap) Cc: Josh Poimboeuf <jpoimboe@redhat.com> Signed-off-by: Jeremy Cline <jcline@redhat.com> Reviewed-by: Josh Poimboeuf <jpoimboe@redhat.com> Signed-off-by: David S.
