From 4f7d54f59bc470f0aaa932f747a95232d7ebf8b1 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Mon, 5 Jan 2009 00:00:12 -0800 Subject: tcp: don't mask EOF and socket errors on nonblocking splice receive Currently, setting SPLICE_F_NONBLOCK on splice from a TCP socket results in masking of EOF (RDHUP) and error conditions on the socket by an -EAGAIN return. Move the NONBLOCK check in tcp_splice_read() to be after the EOF and error checks to fix this. Signed-off-by: Lennert Buytenhek Signed-off-by: David S.
