Date: Tue, 18 Dec 2012 11:05:50 +0800	[thread overview]
Message-ID: <50CFDD8E.2050003@oracle.com> (raw)

Hello,

Here is quick fix for btrfs set lable ioctl(2) based on v5, it does label length check up with
strnlen() to avoid searching a zero could go beyond the page limit touching an un-mapped page
and raising an segmentation fault with strlen().


V6->v5:
- Improve the input label string validation with strnlen().


The old versions can be found at:
v5:

v4:

v3:

v2:
http://permalink.gmane.org/gmane.comp.file-systems.btrfs/12877

v1:
