From c29c3f70c9eb6f18090da5af9dbe9dcb4adece8c Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Tue, 20 Apr 2010 17:58:24 -0400 Subject: tipc: Abort excessive send requests as early as possible Adds checks to TIPC's socket send routines to promptly detect and abort attempts to send more than 66,000 bytes in a single TIPC message or more than 2**31-1 bytes in a single TIPC byte stream request. In addition, this ensures that the number of iovecs in a send request does not exceed the limits of a standard integer variable.
