Subject: No cmsg for SOCK_STREAM?

Hello everybody,

'man 7 ip' sais that IP_RECVOPTS is not supported for SOCK_STREAM  

But what if for debugging/measuring purposes I wanted to record the  
route of the datagrams containing the stream segments? Are there any  
other ways to get the IP options? Like a second raw socket to deliver  
cmsgs to user space and later resubmit for kernel TCP processing and  
normal delivery to application -- if that is possible at all.

Or any other way?

Thanks in advance,
