Message-Id: <C63E4CE2-57E4-446C-B7B0-80D9E506A83C@mac.com> Date: Sat, 14 Jul 2007 11:53:20 +0200 From: Daniel Schaffrath <daniel.schaffrath@....com> To: linux-net@...r.kernel.org, Linux NetDev <netdev@...r.kernel.org> Subject: No cmsg for SOCK_STREAM? Hello everybody, 'man 7 ip' sais that IP_RECVOPTS is not supported for SOCK_STREAM sockets. 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?
