Hello Michael S. Tsirkin, The patch e999d6ea2a4f: "tun: add VNET_LE flag" from Nov 18, 2014, leads to the following static checker warning: drivers/net/tun.c:1694 tun_set_iff() warn: 0x17100 is larger than 16 bits drivers/net/tun.c 1692 1693 tun->flags = (tun->flags & ~TUN_FEATURES) | 1694 (ifr->ifr_flags & TUN_FEATURES); 1695 It's complaining because the "ifr->ifr_flags" variable is a short (should it be unsigned?). The new define: #define IFF_VNET_LE 0x10000 doesn't fit in two bytes. Other suspect looking code could be: return __virtio16_to_cpu(q->flags & IFF_VNET_LE, val); regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
