From cff6b8a9b81b404e8ce0257b26007c3afe625212 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 10 Jul 2010 11:51:54 +0200 Subject: [PATCH] 9p: strlen() doesn't count the terminator This is an off by one bug because strlen() doesn't count the NULL terminator. We strcpy() addr into a fixed length array of size UNIX_PATH_MAX later on. The addr variable is the name of the device being mounted.
