From 50b42d1c5bb19e3a5050d7d23ac96e273d3974ee Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Mon, 4 Mar 2013 14:07:38 +1100 Subject: s4-lib/socket: Return the original EMSGSIZE when sendto() and setsockopt() both fail This ensures that should we be unable to increase the socket size, we return an error that the application layer above might expect and be able to make as reasonable response to (such as switching to a stream-based transport). This fixes up c692bb02b039ae8fef6ba968fd13b36ad7d62a72.
