From 9eb5c94ef217d61d974f384b29b7298490b0a4d9 Mon Sep 17 00:00:00 2001 From: Patrick Caulfield Date: Fri, 11 Nov 2005 12:04:28 -0800 Subject: [PATCH] [DECNET]: fix SIGPIPE Currently recvmsg generates SIGPIPE whereas sendmsg does not; for the other stacks it seems to be the other way round! It also fixes the bug where reading from a socket whose peer has shutdown returned -EINVAL rather than 0. Signed-off-by: Patrick Caulfield Signed-off-by: David S.
