Subject: Mount failure caused by colon/comma characters in the path of lower/upper dirs
Date: Wed, 23 Jun 2021 00:15:14 +0800	[thread overview]
Message-ID: <17a34811bb1.ca67d1a36094.7925246580859918166@mykernel.net> (raw)

Hello,

Today I got a mount failure report from a docker developer about special characters in overlayfs lower/upper path.
The root cause is quite straightforward  because overlayfs uses colon/comma as seperator of lowerdir layers and module options.
However, Colon/Comma characters are valid for directory name on linux so some people(especially container users) hope overlayfs
could correctly recognize and handle those directories.

Strengthen option parsing seems a right solution for fixing the issue, what do think for this?



Thanks,
Chengguang Xu
