Hijacking this thread since I didn't see the causing patch to be posted to lkml. From linux-next:
net/netlink/af_netlink.c: In function 'netlink_queue_mmaped_skb': net/netlink/af_netlink.c:663:14: error: incompatible types when assigning to type '__u32' from type 'kuid_t' net/netlink/af_netlink.c:664:14: error: incompatible types when assigning to type '__u32' from type 'kgid_t' net/netlink/af_netlink.c: In function 'netlink_ring_set_copied': net/netlink/af_netlink.c:693:14: error: incompatible types when assigning to type '__u32' from type 'kuid_t' net/netlink/af_netlink.c:694:14: error: incompatible types when assigning to type '__u32' from type 'kgid_t'
for a config with CONFIG_UIDGID_STRICT_TYPE_CHECKS enabled.
Looks like it's coming from f9c2288837ba ("netlink: implement memory mapped recvmsg()"). Patrick?
