Subject: io-uring and tcp sockets
Date: Mon, 2 Nov 2020 18:56:59 -0700	[thread overview]
Message-ID: <[email protected]> (raw)

Hi:

New to io_uring but can't find this answer online, so reaching out.

I was trying out io_uring with netperf - tcp stream sockets - and
noticed a submission is called complete even with a partial send
(io_send(), ret < sr->len). Saving the offset of what succeeded (plus
some other adjustments) and retrying the sqe again solves the problem.
But the issue seems fundamental so wondering if is intentional?

Thanks,
David
