The msk sk_shutdown flag is set by a workqueue, possibly introducing some delay in user-space notification. If the last subflow carries some data with the fin packet, the user space can wake-up before RCV_SHUTDOWN is set. If it executes unblocking recvmsg(), it may return with an error instead of eof.Address the issue explicitly checking for eof in recvmsg(), when no data is found.
