TCP: sendmsg/recvmsg/ioctl(SIOCINQ/SIOCOUTQ)

["James R. Leu" <jleu@xxxxxxxxxxxxxx>]

It seems that TCPs recvmsg/sendmsg and ioctl for SIOCINQ/SIOCOUTQ do not
check to make sure the socket is connected.

I was unable to find a place that does check to make sure the socket is
connected before doig the above socket ops.

Is it adequte to do:

                if (sk->state != TCPF_ESTABLISHED)
                        return(-ENOTCONN);

to determin if a TCP socket is connected?  Where should this check (or another
more appropriate check) be made?

Thanks,
Jim

PS I'm working with 2.4.0
