Hello Jiri Benc, The patch 54bfd872bf16: "vxlan: keep flags and vni in network byte order" from Feb 16, 2016, leads to the following static checker warning: ./include/net/vxlan.h:340 vxlan_vni() warn: potential shift truncation. '0xffffff00 << 8' include/net/vxlan.h 335 static inline __be32 vxlan_vni(__be32 vni_field) 336 { 337 #if defined(__BIG_ENDIAN) 338 return (__force __be32)((__force u32)vni_field >> 8); 339 #else 340 return (__force __be32)((__force u32)(vni_field & VXLAN_VNI_MASK) << 8); Are you sure this is correct? VXLAN_VNI_MASK already has an << 8 shift so this feels like maybe it is a double shift. 341 #endif 342 } 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
