From 49c794e94649020248e37b78db16cd25bad38b4f Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Tue, 4 Aug 2009 07:28:28 +0000 Subject: net: implement a SO_PROTOCOL getsockoption Similar to SO_TYPE returning the socket type, SO_PROTOCOL allows to retrieve the protocol used with a given socket. I am not quite sure why we have that-many copies of socket.h, and why the values are not the same on all arches either, but for where hex numbers dominate, I use 0x1029 for SO_PROTOCOL as that seems to be the next free unused number across a bunch of operating systems, or so Google results make me want to believe. SO_PROTOCOL for others just uses the next free Linux number, 38. Signed-off-by: Jan Engelhardt Signed-off-by: David S.
