From 374e7b59498ce0785b3727794b351221528a5159 Mon Sep 17 00:00:00 2001 From: Octavian Purdila Date: Thu, 3 Jul 2008 03:31:21 -0700 Subject: [PATCH] tcp: fix a size_t < 0 comparison in tcp_read_sock should be of type int (not size_t) since recv_actor can return negative values and it is also used in a < 0 comparison.
