From: Hendrik Brueckner Date: Tue, 6 Jan 2009 02:07:07 +0000 (-0800) Subject: af_iucv: New error return codes for connect() X-Git-Tag: v3.0~11453^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=55cdea9ed9cf2d76993e40ed7a1fc649a14db07c;p=platform%2Fkernel%2Flinux-amlogic.git af_iucv: New error return codes for connect() If the iucv_path_connect() call fails then return an error code that corresponds to the iucv_path_connect() failure condition; instead of returning -ECONNREFUSED for any failure. This helps to improve error handling for user space applications (e.g. inform the user that the z/VM guest is not authorized to connect to other guest virtual machines). The error return codes are based on those described in connect(2). Signed-off-by: Hendrik Brueckner Signed-off-by: Ursula Braun Signed-off-by: David S.
