Description Jeremy Harris 2016-10-22 18:04:50 EDT

Description of problem:

 The kernel supports TCP_FASTOPEN (the system include files have it, the
/proc/sys/net/ipv4/tcp_fastopen magic file exists) but there is no definition
of MSG_FASTOPEN (required for applications using the feature to build).

Version-Release number of selected component (if applicable):
  glibc-headers-2.17

How reproducible:
 100%


Additional info:
 F24, with glibc-headers-2.23.1  has it present in /usr/include/bits/socket.h

Comment 3 Jeremy Harris 2016-10-24 06:09:47 EDT

I was attempting to compile a (bleeding-edge development version) of an
application which can use TCP Fast Open (RFC 7413).  The specific application,
Exim, is not delivered by Red Hat but is the globally dominant internet-facing MTA
according to one scanning site.

TCP Fast Open is also expected to be of interest for general web access
(it can remove one roundtrip time; important for shortlived connections).
