Subject: [Virtio-fs] [virtiofsd] MR opened: Draft: enabling a non-root user to set the UID/GID mappings inside a sandbox
Date: Thu, 8 Sep 2022 20:50:04 +0000 (UTC) [thread overview]
Message-ID: <91993.122090816500001879@us-mta-447.us.mimecast.lan> (raw)
This patch enables a non-root user to map a set of UID/GID mappings from a namespace to another set outside the namespace. Since unshare is used on the main thread of the virtiofsd, once the thread goes inside a namespace it is not able to map a range of UID/GID other than the current user/group that is running the virtiofsd. This patch enables a non-root user with CAP_SETUID, CAP_SETGID capabilities to set multiple mappings and then drop those capabilities. The UID/GID ranges can be specified using virtiofsd command line parameters.
