From 6a86bb6c25376f0358478219fa28d7c84dd01ed0 Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Mon, 1 Dec 2008 16:29:38 -0600 Subject: [PATCH] net: Fix TftpStart() ip:filename bug The TftpStart() function modifies the 'BootFile' string when 'BootFile' contains both an IP address and filename (eg 1.2.3.4:/path/file). This causes subsequent calls to TftpStart to incorrectly parse the TFTP filename and server IP address to use. For example: => tftp 0x100000 10.52.0.62:/home/ptyser/non_existant Speed: 100, half duplex Using eTSEC1 device TFTP from server 10.52.0.62; our IP address is 10.52.253.79 ^^^^^^^^^^ CORRECT Filename '/home/ptyser/non_existant'. ^^^^^^^^^^^^^^^^^^^^^^^^^ CORRECT Load address: 0x100000 Loading: * TFTP error: 'File not found' (1) Starting again eTSEC2: No link. Speed: 100, half duplex Using eTSEC1 device TFTP from server 10.52.0.33; our IP address is 10.52.253.79 ^^^^^^^^^^ WRONG Filename '10.52.0.62'. ^^^^^^^^^^ WRONG Load address: 0x100000 Loading: * TFTP error: 'File not found' (1) Starting again TftpStart() was modified to not modify the 'BootFile' string.
