From: Dan Carpenter Date: Fri, 9 Jul 2010 23:51:54 +0000 (+0000) Subject: 9p: strlen() doesn't count the terminator X-Git-Tag: MMI-PSA29.97-13-9~23092^2~259 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5c4bfa17f3ec46becec4b23d12323f7605ebd696;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git 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.
