Vasily Averin 08b11eaccf scsi: libiscsi: fall back to sendmsg for slab pages ... In "XFS over network block device" scenario XFS can create IO requests with slab-based XFS metadata. During processing such requests tcp_sendpage() can merge skb fragments with neighbour slab objects. If receiving side is located on the same host tcp_recvmsg() can trigger BUG_ON in hardening check and crash the host with following message: usercopy: kernel memory exposure attempt detected from XXXXXXXX (kmalloc-512) (1024 bytes) This patch redirect such requests from sednpage to sendmsg path. The problem is similar to one described in recent commit 7e241f647d ("libceph: fall back to sendmsg for slab pages") Signed-off-by: Vasily Averin <vvs@virtuozzo.com> Acked-by: Chris Leech <cleech@redhat.com> Signed-off-by: Martin K.
